[0002] Waterproof coating refers to the coating used to prevent water intrusion and leakage. The waterproof film formed after curing of the waterproof coating has certain extensibility, elasticity, crack resistance, impermeability and weather resistance, which can play a role in waterproofing and waterproofing. Infiltration and protection, waterproof coatings have good temperature adaptability, easy operation, and easy repair and maintenance. There are two types of waterproof materials on the market: one is polyurethane waterproof coatings, which are generally made of polyurethane and coal. Tar is made as a raw material, and the tar gas it volatilizes is highly toxic and not easy to re...

Embodiment 2

[0025] A polystyrene elastic waterproof coating is characterized in that it is made up of the raw materials of the following components:

[0026]

[0027]

[0028] The method for preparing polystyrene elastic waterproof coating of the present invention comprises the following processing steps:

[0029] a. Weigh the polystyrene foam according to the formula quantity, and then cut it to a length of 2-4cm.

[0030] b. choose a reactor that is provided with a jacket, put all the polystyrene foam plastics after cutting in step a into it, then add rosin, ethyl acetate, toluene, solvent naphtha and toluene in the above-mentioned raw materials according to the formula amount Diisocyanate is added to it, under constant stirring and heated to 48-58°C, react for 4-5h.

[0031] c. After the reaction in the above step b is completed, add the regenerated rubber industry in the above solution into the reaction kettle according to the formula amount, and stir evenly.

[0032] d. The m...

Abstract

The invention discloses a preparation method for a polystyrene elastic waterproof coating, and relates to the technical field of chemical engineering. The coating is composed of the following raw materials: 95-105 parts of polystyrene foam, 10-14 parts of rosin, 56-60 parts of ethyl acetate, 30-40 parts of toluene, 50-60 parts of solvent naphtha, 3-5 parts of toluene diisocyanate and 25-35 parts of a reclaimed rubber solution. The beneficial effects comprise that the preparation method is convenient and simple, easily available in raw materials, less in equipment investment and convenient to operate, and the prepared polystyrene elastic waterproof coating is environment-friendly, free of pollution, high in purity, good in usage effect, strong in high-temperature resistance, safe and reliable.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a preparation method of polystyrene elastic waterproof coating. Background technique [0002] Waterproof coating refers to the coating used to prevent water intrusion and leakage. The waterproof film formed after curing of the waterproof coating has certain extensibility, elasticity, crack resistance, impermeability and weather resistance, which can play a role in waterproofing and waterproofing. Infiltration and protection, waterproof coatings have good temperature adaptability, easy operation, and easy repair and maintenance. There are two types of waterproof materials on the market: one is polyurethane waterproof coatings, which are generally made of polyurethane and coal. Tar is made as a raw material, and the tar gas it volatilizes is highly toxic and not easy to remove, so it was banned in China in 2000. The polyurethane waterproof coating that is still on the mar...
