A WALL TILE WITH POROUS COMPOSITE
FIELD OF THE INVENTION
The present invention provides porous composite for the manufacturing of wall tile. It also provides the process for making said porous composite.
BACKGROUND OF THE INVENTION
We spend majorly of our time living in spaces surrounded by bordering walls usually covered with chemical paint or tiles of various types. It is a minimum expectation that where we spend more time in the area it should be pollution free, heat-insulated to control the room temperature in all seasons as well as it should be sound insulated also. Most importantly opting to products that are produced through polluting process always contribute to degrading nature. Some products like chemical paints generate harmful and toxic fumes after usage for several weeks or rather months which affects the user at major level and the environment in micro level, however the aspect that across the world a large number of chemical paints being opted makes it a serious concern whether the fumes that exit a living space might possibly cause an after effect to the environment in near future.
As stated by Environmental Protection Agency (EPA), the effects of evaporating paint are far stronger indoors than out. The (EPA) estimates that indoor volatile organic compounds (VOCs) are normally two to five times higher than outdoor levels. During activities like stripping paint, indoor levels can be 1,000 times the outdoor levels. Some VOCs are harmless, even in a confined space like a home. Others are potentially lethal carcinogens. Most of the off-gassing of interior paint takes place in the early days after painting but the paint can continue emitting VOCs for years, posing an ongoing threat to health. For someone who makes the mistake of applying an exterior paint to an interior surface, the potentially dangerous offgassing can continue for far longer. According to the EPA, some of the health dangers of VOC exposure include:
Irritation of the eyes, nose, and throat Headaches
» Organ damage
» Allergic skin reactions
" Fatigue
Nausea and/or vomiting
Visual disorders
» Impaired memory
» Some compounds are suspected or known to cause cancer
At present the products available in form of tile that apply or cover wall are such as foam-based tiles, ceramic, porcelain, stone, metal, or even glass material. The said tiles materials usually have some advantages and disadvantages. Advantages, having to be easy to maintain, water-resistant, and durable. Whereas, disadvantages having, not working as a heat insulator means being unable to maintain the room temperature constant in all seasons, and the manufacturing process contributes to air or water pollution directly or indirectly. The existing available alternates also require skilled labour to apply and needs time to install.
Living in a suburb with so many residents, always have complained about illness as stated in the list above and noise emanating from several sources. The disturbance has made it almost impossible to find total peace in our residence or our working area. Soundproofing of the working place can change the quality of life for the better. Reducing sound in leaving the area is the surest way to give maximum relaxation to the person who stays in that area. So, heat insulation and soundproofing working areas are being today’s utmost need.
The problem has motivated us to invent a solution that can replace polluting effect of chemical paints, Polyurethane, pvc foam-based tiles and is easier to install and replace than ceramic, glass tiles etc. The present porous composite is completely organic, recyclable, manufactured chemically free, is affordable and abundant, has very less or no effect on environment for production, application and maintenance, is easy to install and replace.
The present innovation comes up with a porous composite that can be shaped into desired form to function as furniture, indoor articles, flooring overlays or tiles that can be applied to cover new and existing wall surfaces that surround indoor spaces. The porous composite is made up of organic bio-friendly materials selected from bagasse, pulpwood, and wheat in combination with suitable filler(s) and binder that can absorb the sound to reduce reverb and is also able to dampen heat in the internal space of the working area.
The present invention is mitigating the above-mentioned problems. The present invention provides the porous composite for the manufacturing of wall tile to replace currently available said products that generate pollution, dampen heat transfer from external environment along with soundproofing advantageous.

Tests for air pollutants emission, volatile organic compounds (VOC): Volatile organic compounds have lower boiling point and tend to create fumes easily. These fumes typically consist of n-Butanol, Styrene, (1 -Methylethyl) benzene, Propylbenzene, Benzaldehyde, Ethyl- 1 -hexanol, Ethylhexyl acetate, 2- Ethylhexyl acrylate, Octyl propionate etc. which cause harmful effects when human skin is exposed and or breathed.
The objective is to simulate a prototype indoor room/space and compare between painted and inventive material samples applied with respect to amount of VOC emitted by each sample specimen.
To conduct the tests, 40 pieces of cement sheet were taken to form the walls of testing cube, the size of each cement sheet is 12 inches x 12 inches x 9mm. The 40 pieces of cement sheet are separated in a group of 8 each group consisting 5 pieces of cement sheet.
The first group (group 1) of 5 sheets were painted with single coat of “solar half’ shade plastic paint, the paint was applied on one side of each sheet.
The second group (group 2) of 5 sheets were painted with single coat of “orange spark” shade plastic paint, the paint was applied on one side of each sheet.
Group 3, group 4, group 5, group 6, group 7, group 8 were coated with single layer inventive sample material A, B, C, D, E, F respectively by gluing over one side of every sheet using casein glue.
After drying, the first group of paint coated sheets was assembled by joining edge to edge using silicon glue such that each sheet is perpendicular to adjoining sheet in order to form a cube with one side open. While assembling the cube, the coated surface of each group is chosen to form the internal surface and non-coated surface form the external surface. The cube now includes a bottom side SC5, three perpendicular sides SC2, SC3, SC4, one top side SCI and one side CSO. This open side represents window(s) and door(s) that cause air exchange across the room. Refer figure 10, illustrating cube specimen made from five cement sheets and one side is kept open. The first group of sheets (group 1) assembled into a cube with one side open is hereafter called as cube Pl. Similarly, the group 2, group 3, group 4, group 5, group 6, group 7, group 8 are assembled into cube P2, cube U, cube V, cube W, cube X, cube Y, cube Z.
The cube specimens with respect to samples applied are stated as follows
To determine the VOC content, a portable Total VOC measuring meter OC-904 PID Sensor (MVOC) is used. The figure 10 illustrates the setup arrangement of the tests Testing data
Each cube was placed over a bench of height 3 feet from ground, the cube samples were rested on bottom side defined as SC5. The test started on 17th January 2021 in the outdoor, the ambient temperature was measured 27 Deg C and Relative humidity was 80% RH during the test. The reading from MVOC was recorded every day at 12pm noon for continuous 11 days to understand the variance in VOC peak and saturation level. The MVOC meter was pre calibrated before collecting the data. The measuring tip of handheld MVOC meter was holded at center of cube through the open side of cube CSO.
Conclusion: As observed from data, VOCs evolved from chemical paint are found to be up to 1344PPB. Whereas as per the standards of OSHA occupational safety and health administration and EPA the safe limits are 0-300ppb. Referring to the trials the paint samples space A and space B emit up to 4.5 times the values indicated as safe limit and continues to be out of safe limit for 11 days. Whereas the test was carried for only single coat of sample 1 and sample 2 over surface area equivalent to 5*12*12 = 720sqin eq to 0.4645sqm only.
Referring to the tests it can be concluded that application of material can reduce pollution effect on indoor space if chemical-based paint is replaced by proposed inventive material. Also, the material in the form of tile is equally aesthetic when compared with chemical paint-based wall surface. The material can thus be concluded as a viable and pollution free alternative for chemical paints.
The porous composite for a wall tile wherein the porous composite(s) has ability to reduce the pollution effect on indoor space by replacing the chemical-based paint.
Testing of particulate matter absorption:
The test is carried out to compare inventive material with ceramic tiles & painted samples to determine the ability to arrest particulate matter contents from air. For carrying out tests, a cylindrical glass beaker of 100mm internal diameter and 200mm height 2mm thickness is used as enclosure. Within the enclosure the sample, particulate matter generating source and particulate monitoring sensor is placed. The source of particulate matter selected is an incense stick Loban Dhoop (10 grams incense) each of the incense burned for 2 hours continuously. A weighing device used was Glass enclosed MS Semi-Micro Balances of MT make with measuring capacity of 220gm and measurability of O.Olmg change in weight.

Testing of recyclability of invented material (additional test)
The objective of this test is to check the recyclability aspect of proposed inventive material. The test Sample C is selected in this test. Following steps are performed
1. The sample C is cut into 1 inch pieces and put into a grinder along with 100ml water. The aim is to grind the paper mass for 20-25 minutes until a smooth paste is obtained.
2. The pulp once ready is transferred to a tray out from the grinding vessel.
3. The pulp mass is made to evenly lay over female press area and the male dye piece is placed over the pulp content. A pressure equivalent to 280-290 KPA was applied through a Weight-force of 1500Kg evenly across the surface of dye plate gradually using screw press assembly to compress both male and female plates causing the pulp to compress. The force is continually added until a point arrives where the pulp has compressed upto 50-60% of its volume. This compression rate can be tracked by simply marking the initial and final displacement of female plate before and after compression. The temperature during this compression process is constant, ambient initially and after the process.
4. After compression of pulp, let the free water completely drain from release pores of mold. At this point of time, the compressed tile still has 25-30% moisture and the tile is delicate
5. For complete drying, an oven is preheated at 140Deg C, the sample is kept inside the oven for 15 minutes at 140Deg C.
6. After complete drying, the tile acoustic resonance makes wood like resemblance when knocked on indicating that it is fairly dry enough to be used for.
7. The re-processed tile depicts physical properties exactly similar to actual sample C tile
Testing of re-processed tile in comparison of original tile
Conclusion: The test depicts the ability of proposed inventive material to be easily recycled. Due to limitations in access to machinery that involve recyclability test of comparative materials we have not performed the tests, however currently available products like Chemical paint, Ceramic wall tiles, PVC foam tiles no-where state recyclability of respective materials.
The porous composite for a wall tile wherein the porous composite(s) is recyclable.
The present wall tile(s) consist majority of a base material that can also support growth of genetically designed plants. Due to its porous nature, roots can well develop across the material and hence it can be possible to achieve vertical plantation in indoors with replaceable section tiles. Due to technological limitation, it is difficult to develop the end result but plants/creepers that survive in low ambient light, able to transpire, have surface ability to generate wax or hairy structures like silver birch, can emit illuminating effect through bioluminescence. These features when achieved in future can allow us to have a breathing wall material that naturally absorb CO2 and emit oxygen, the surface structures can enhance that ability of settling particulate matter, the illuminating bioluminescence can add lighting to the indoors.
The inventive material is proposed to be alternative to laminates, veneers etc. which are applied over wooden furniture for aesthetic purpose.
