Problems solved by technology

[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.

Embodiment 2

[0028] A water-emulsion type reclaimed rubber modified asphalt waterproof coating is composed of the following raw materials:

[0029]

[0030] The method for preparing the water-emulsion type reclaimed rubber modified asphalt waterproof coating of the present invention comprises the following process steps:

[0031] a. Add the water in the raw material into the mixing mixer according to 50% of the formula amount, then heat it to boiling, then add the caustic soda in the raw material, and stir until it dissolves.

[0032] b. After the caustic soda in step a is dissolved, continue to stir, put the soap box water glass in the raw material into the mixing mixer according to the formula amount, then raise the temperature to 40-50°C, and stir well to obtain A clear anionic emulsifier, stored at a temperature between 60-80°C for future use.

[0033] c. Select a melting tank, add the petroleum pitch in the raw material into the melting tank according to the formula amount, heat a...
