Abstract

The invention discloses a polystyrene plastic coating. The polystyrene plastic coating is prepared from polystyrene plastic, a butyl acetate solution, a cyclohexanone solution, a methylbenzene solution, active nano-calcium carbonate, polyoxypropylene glycerol ether, an antioxidant DNP, epoxy resin adhesive, water, a DEHP plasticizer, OP-10 and sodium dodecyl benzene sulfonate. The preparation method of the polystyrene plastic coating comprises the following steps: (a) crushing the polystyrene plastic until the volume of the polystyrene plastic is 0.1 to 0.25cm<3> and then washing and drying; (b) adding the crushed polystyrene plastic into a stirring vessel which holds the butyl acetate solution, the cyclohexanone solution and the methylbenzene solution, heating and stirring; (c) filteringmaterials obtained in the (b), adding the active nano-calcium carbonate, the polyoxypropylene glycerol ether, the antioxidant DNP, the epoxy resin adhesive, the water, the DEHP plasticizer, the OP-10and the sodium dodecyl benzene sulfonate, heating, stirring and then cooling, thus obtaining a finished product. According to the polystyrene plastic coating disclosed by the invention, secondary useand multiple use of the plastics are realized; in addition, the coating has the advantages of excellent waterproof property, toughness, stability, smoothness and adhesion.

Description

technical field [0001] The invention relates to a polystyrene plastic paint and belongs to the field of paint. Background technique [0002] Polystyrene (PS) is a thermoplastic resin that is widely used due to its low price and easy processing and molding. However, due to its small quality (especially the foam type) and low residual value, polystyrene is not easy to recycle, and generally polystyrene cannot be recycled by the kerbside method. Discarded polystyrene cannot enter the biogeochemical cycle through biodegradation and photolysis. Due to the low specific gravity of expanded polystyrene (polystyrene), it floats on the water surface or drifts with the wind, causing subjective landscape damage. Styrene is also a major ocean flotsam. For marine organisms that eat this type of plastic by mistake, it will cause damage to their digestive system. Therefore, the processing prospect of polystyrene plastic is very broad, and recycling is the only way for the sustainable dev...
