Problems solved by technology

The polyurethane waterproof coatings that are still on the market use asphalt instead of coal tar as the raw material, but they need to be melted at high temperature in the production process, and then mixed with organic solvents such as benzene after a period of cooling. The process is backward and the operation is very cumbersome. , and the performance is poor, the service life is short, and the leakage phenomenon of the building is quite common.
In addition, asphalt is recognized as poisonous in the world, and the benzene used in processing is a strong carcinogen, which is very toxic, causing great harm to the human body and polluting the environment.

Description

technical field [0001] The invention relates to a waterproof coating and its preparation process, in particular to an environment-friendly colored polyurethane waterproof coating and its preparation process. technical background [0002] Polyurethane waterproof coatings are widely used waterproof materials at present. The first generation of polyurethane waterproof coatings is made of polyurethane and coal tar as raw materials, but because coal tar will cause poison to the human body, in It was banned in my country in 2000. The polyurethane waterproof coatings that are still on the market use asphalt instead of coal tar as the raw material. However, during the production process, it needs to be melted at high temperature, and then mixed with organic solvents such as benzene after a period of cooling. The process is backward and the operation is very cumbersome. , and poor performance, short service life, resulting in building leakage is quite common. In addition, asphalt is...
