Technical field

The invention belongs to the technical field of chemical equipment, and is specifically an efficient production device for polyurethane waterproof coating.

Background technique

Polyurethane waterproof coating, also known as polyurethane coating waterproof material, is a type of polymer waterproof coating with polyurethane resin as the main film-forming substance. It is made of a mixture of isocyanate-based curing agent and other additives in a certain proportion, without tar and Asphalt and other additives are a one-component environmentally friendly waterproof coating constructed in a liquid state. It solidifies upon contact with moisture in the air, forming a strong and tough seamless overall waterproof membrane on the surface of the base layer.

For this kind of material, it has very good ductility and elasticity, and it is also a colorless and odorless product. It is relatively good in terms of environmental protection, but it has very good viscosity before drying. If it is accidentally bumped or contacted, it will cause damage to the waterproof film. After drying, it is basically transparent, which is very good from a visual point of view.

Based on the many characteristics of polyurethane, it has an extremely wide range of applications. The preparation of rolling paper is relatively simple.
