Method for preparing high performance water proof anti-corrosive paint

Abstract

The present invention discloses a method for preparing high performance water-proofing and anti-corrosion paint. The components of the water-proofing and anti-corrosion paint take waste polystyrene plastic foams as a basal material. The water-proofing and anti-corrosion paint also comprises rubber, colophony, ethyl acetate, toluene, solvent and toluene di-isocyanate. According to weight portion mixture ratio, the basal material is weighted by 100 weight portion, and other components by weight portion of the water-proofing and anti-corrosion paint are: 30 to 60 weight portions of rubber, 10 to 20 weight portions of colophony, 30 to 60 weight portions of ethyl acetate, 30 to 60 weight portions of toluene, 50 to 70 weight portions of solvent and 1 to 5 weight portions of toluene toluene di-isocyanate. The preparing method comprises the following steps: firstly, placing fragments of the waste polystyrene plastic foams used as the basal material in a reactor; secondly, adding the colophony, the ethyl acetate, the toluene, the solvent and the toluene toluene di-isocyanate according to the mixture ratio, heating and dissolving the form plastics to be foamless; and finally, adding the rubber, mixing the components to be pasty, pulling out filaments and filtering. The paint prepared by the method has the advantages of high dispersity and penetrability, good weather resistance, acid, base and high temperature resistance, low preservation requirement, stable performance, simple preparing process, low process condition and low integrated cost. In addition, the method uses the waste polystyrene plastic foams as the basal material, thereby making waste into valuable and reducing the white pollution.

Description

technical field [0001] The invention relates to a preparation method of a high-performance waterproof and anti-corrosion paint mainly using waste polystyrene foam as a base material. Background technique [0002] Leakage and waterproofing of buildings has always been a major problem in the construction industry. Some existing coatings, such as polyvinyl chloride (PVC) elastic waterproof coatings, waterproof coatings with coal tar and asphalt, waterproof coatings using neoprene, 851 tar polyurethane, etc., have high engineering costs and high costs. , complex process, pollute the environment, endanger human health and other issues. In addition, there is a large amount of waste polystyrene foam that seriously pollutes the environment. CN1107869A patent application discloses a colorful elastic waterproof coating, which is based on vinyl acetate-ethylene copolymer emulsion and added with alkaline regulator, modifier, composite dispersant, filling material, colorant, stabilizer...
