Abstract

The invention relates to waterproof paint. In a process, waste polystyrene foam plastics are used for being made into water emulsion waterproof paint. The invention provides flat, smooth and high-stability waterproof paint. A recipe of the waterproof paint comprises 12g of polystyrene (PS) foam, 20.1g of mixed solvents, 0.8g of plasticizers (dimethyl terephthalate), 2.88g of emulsifying agents, 1.2g of maleic anhydride and 3g of rosin, wherein the volume ratio of the water phase to the oil phase is 2:1.

Description

Technical field: [0001] The invention relates to a waterproof coating. The process uses waste polystyrene foam plastic to make a water-emulsion waterproof coating. Background technique: [0002] Polystyrene foam is a molded foam of expandable polystyrene vinyl body. It has excellent characteristics such as heat insulation, sound insulation, shockproof, waterproof, acid and alkali resistance, and has the advantages of light weight and beautiful appearance. It is widely used It is used in the packaging of household appliances, precision instruments, electronic products and food, but most of them are disposable and become waste products after use. According to statistics from relevant departments, the current annual demand for polystyrene foam in my country is about 1.5 million tons, and it is increasing at an annual rate of 10%, of which about 23% is abandoned. At present, the annual waste of polystyrene foam packaging materials for TV sets alone is more than 15,000 tons, and the ...
