Title:
METHOD FOR PREPARING HYDROPHOBIC AND OLEOPHYLIC MARINE CONCRETE CAPABLE OF DEGRADING OIL
Document Type and Number:
WIPO Patent Application WO/2020/200169
Kind Code:
A1
Abstract:
Disclosed is a method for preparing hydrophobic and oleophylic marine concrete capable of degrading oil. The method comprises: choosing cement, sand, absolute ethyl alcohol, water and stearic acid as raw materials; first stirring the stearic acid and the absolute ethyl alcohol to form a mixed solution by using a magnetic stirrer; then mixing the mixed solution with the cement, the sand and the water to make fresh concrete; covering an inner side wall and a bottom wall of a mold with a red copper mesh, then placing the fresh concrete in the mold, also adding bacillus-coated microcapsules into the mold, vibrating the concrete, scraping the surface of the concrete to be flat after the vibration is finished, and finally covering the top of the concrete with a copper mesh; and hardening and demolding the concrete at room temperature, removing the copper mesh, and placing the concrete in a standard curing box for curing to obtain the hydrophobic and oleophylic marine concrete capable of degrading oil. The hydrophobic and oleophylic marine concrete capable of degrading oil has a surface that not only has a hydrophobic performance, but can also absorb oil leaked into the sea and automatically degrade the oil, thereby relieving the problem of marine oil pollution.
