Preparation method of solvent-type polystyrene modified asphalt waterproof paint

Abstract

The invention discloses a preparation method of a solvent-type polystyrene modified asphalt waterproof paint, and relates to the technical field of chemical engineering. The paint is composed of the following raw materials in parts by weight: 7.9 to 8.1 parts of polystyrene, 24.0 to 24.2 parts of petroleum asphalt, 14.0 to 14.2 parts of xylene, 22.0 to 22.2 parts of dichloropropane, 1.1 to 1.3 parts of methylphenol, 14.0 to 14.2 parts of talcum powder, 2.3 to 2.5 parts of plasticizer, 5.9 to 6.1 part of stuffing material, and 7.9 to 8.1 parts of solvent oil. The preparation method has the advantages of simpleness, convenience, available raw materials, little equipment investment, and convenient operation. The prepared solvent-type polystyrene modified asphalt waterproof paint has the advantages of environment-friendliness, no pollution, high purity, good using effect, strong high-temperature resistant performance, safety, and reliability.

Description

technical field [0001] The invention relates to the technical field of chemical industry, in particular to a method for preparing a solvent-based polystyrene modified asphalt 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 ...

[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 market uses pitch instead of coal tar as a raw material, but When using this kind of paint, it is generally diluted with organic solvents such as toluene and xylene, so it is also toxic; at the same time, it is inconvenient to construct, the overall cost is high, the construction period is short and long, and the environmental protection is relatively poor, but even with so many However, due to the lack of technology for the production of waterproof coatings at present, the degree of choice is very low. Most of the waterproof coatings used in the market are still this type of waterproof coatings.
