Title:
INSULATION COMPOSITE PANEL
Document Type and Number:
WIPO Patent Application WO/2013/173889
Kind Code:
A2
Abstract:
Utility model in the field of construction products and refers to the construction of a composite insulation panel. The composite panel consists of a single layer of polyurethane foam (1) with a thickness of more than 20 mm. The second layer is a fiberglass cloth (2) with a thickness of not more than 2 mm. The two layers are glued to one another. On the periphery of the panel a glab (6 and 7) to the two neighboring sides and a tooth respectively (5 and 8) to the opposite of these sides are made to eliminate any thermal bridge during installation. In this case the fiberglass cloth (2) extends beyond the dimensions of the polyurethane foam (1) with not more than 40 mm. in the two neighboring sides.

Description:
INSULATION COMPOSITE PANEL

FIELD OF THE MODEL

The utility model is in the field of construction products and refers to the construction of the composite insulation panel.

BACKGROUND OF THE UTILITY MODEL

Known is panel [1] representing an insulating decorative plate which is composed of a layer of polyurethane foam and fiber concrete layer on one side of the layer of polyurethane foam.

The other side of the fiber concrete layer has edges connecting layer which is a layer of cement glue or a line of polyurethane adhesive.

Summary of utility model

The object is to create a panel in which production wet processes lack whereas there is no drying or evaporation.

This object is achieved by a composite panel consisting of a layer of insulating material having a closed cell structure and a layer of non-flammable fabric.

The insulating layer is a polyurethane foam or polyisocyanurate foam, or EPS, or XPS- with a thickness of more than 20 mm.

The second layer is a fiberglass cloth with a thickness of not more than 2 mm.

The two layers are glued to one another.

On the periphery of the panel are made a glab to two adjacent sides and an opposing tooth to these two sides.

Fiberglass cloth extends beyond the dimensions of polyurethane foam with no more than 40 mm. in the two neighboring sides 2

For complete coverage a decorative polymer coating is used with a thickness of less than 3 mm.

The above-described panel is intended for external and internal uses.

The utility model has advantages for easy construction, combination of thermal insulation and decorative effects, perfect thermal insulating effect, non-toxic, fire-proved and has a wide applicability.

In addition, the utility model has the capability to adapt to large-scale and continuous industrial production and has a stable quality. DESCRIPTION OF THE DRAWINGS

Figure N° 1 shows the composite panel of polyurethane foam and fiberglass cloth.

N° Figure 2 shows a composite panel of polyisocyanurate foam and fiberglass cloth.

Figure N° 3 shows the composite panel of polyisocyanurate foam and decorative polymer coating.

Figure N° 4 shows a composite panel of polyurethane foam and decorative polymeric coating.

EXAMPLES OF EMBODIMENT OF THE UTILITY MODEL

One embodiment of the utility model is shown in Figure 1. In this case, the composite panel comprises a layer of insulating material having a closed cell structure and a layer of nonflammable fabric.

The insulating layer is a polyurethane foam 1 with a thickness of more than 20 mm.

The second layer is a fiberglass cloth 2 with a thickness of less than 2 mm.

The two layers are glued to one another.

On the periphery of panel 3 a glab 6 and 7 is made to both neighboring sides and a tooth respectively 5 and 8 to the opposite of these sides, which eliminates any thermal bridge during installation.

In this case the fiberglass fabric 2 extends beyond the dimensions of the polyurethane foam 1 with not more than 40 mm. in the two neighboring sides.

In another embodiment shown in Figure 2 the insulation material with a closed cell structure is polyisocyanurate foam 4.

In this case, the other layer is a fiberglass cloth 2 with a thickness of not more than 2 mm.

Another embodiment of the utility model is shown in Figure 3. This panel consists of an insulating material with closed cell structure of polyisocyanurate foam 4 and finishing decorative polymer coating 3 with a thickness less than 3 mm.

Implementation the utility model

Technological equipment necessary for the use of composite panels is as follows: knife; silicone cups 100ml.; mixers; dosing system; leveling system and plumbing; scaffolding platform; foam gun; airless spray glue machine; wallpaper cutting table; airless facade paint spray machine. Necessary raw materials for the installation of composite panels: polyurethane foam system - retainer; one-component polyurethane foam adhesive; polyurethane or epoxy glue; wallpaper for exterior use and a cleaner.

The preparation for the installation of composite panels on a facade of a building includes: standing of a scaffold around the building or mounting a platform; making measurements of the facade and making an action plan.

Installation of composite panels starts from the corners. The surface and the cracks in the walls are cleaned from dust, grease, spray, fatty spots and salting.

After cleaning the polluted areas are washed and dried. Prior to washing with water, the fatty stains are treated with 2% hydrochloric acid solution.

Resurfaced salting is removed completely.

Salt cleaned areas are washed and dried to a moisture content of not more than 8%.

In both cases, upon application of the polyurethane foam glue with a gun in strips on the back of the panel and on the wall the surrounding temperature and the temperature of the basis must be between +5 ° C and +40 ° C.

The base, especially for metal surfaces must be dry and free of oil, as the integrity and load capacity of the base (especially for application on walls) is revised.

Steps for installation.

The bottle of glue is shaken for about 30 seconds, turned upside down and screwed to the gun for polyurethane foam.

Vial is held in an upright position during application.

Composite panels must be applied within a maximum of 10 minutes after the adhesive is applied.

Curing time of the adhesive depends on the temperature and humidity.

Therefore moisture is measured before the start of the workflow.

In dry weather conditions the curing time of the adhesive can be reduced by spraying water onto the strips of polyurethane adhesive.

Before placing the adjacent panel, the side which is to be closed is covered with a polyurethane adhesive prior to installation.
