Embodiment Construction

[0016] Such as figure 1 As shown, a two-component polyurethane waterproof coating structure of the present invention includes a base layer 1, an adhesive layer 2, a spacer layer 3 and a waterproof layer 4; the base layer 1 is arranged at the bottom, and the adhesive layer 2 is arranged on the base layer 1, the spacer layer 3 is set on the adhesive layer 2, and the waterproof layer 4 is set on the spacer layer 3. The base layer 1 is made of metal or non-metal material. The adhesive layer 2 is a modified epoxy resin material. The spacer layer 3 is a nano-material with a double-layer protrusion structure on the surface. The waterproof layer 4 is a two-component polyurethane coating composed of two main components: prepolymer and coal tar-free asphalt paste, and other auxiliary agents and additives.

[0017] The base layer 1 is made of metal or non-metal material, which broadens the installation scope of this structure. Adhesive layer 2 is a modified epoxy resin material. The ...

Abstract

The invention provides a double-component polyurethane waterproof coating structure. The double-component polyurethane waterproof coating structure comprises a base layer, a bonding layer, a spacing layer and a waterproof layer, wherein the base layer is arranged at the bottommost portion, the bonding layer is arranged above the base layer, the spacing layer is arranged above the bonding layer and the waterproof layer is arranged above the spacing layer; the base layer is made of a metallic or nonmetallic material, the bonding layer is made of a modified epoxy resin material, the spacing layer is made of a nano material with a double-layer protruding structure on the surface, and the waterproof layer is a double-component polyurethane coating consisting of two main components, i.e., prepolymer and asphalt paste containing no coal tar, catalyst and other additives. The double-component polyurethane waterproof coating structure has the advantages of simple structure, high practicability, strong impact resistance, high water-tightness and strong waterproof and anti-seepage performance.

Description

technical field [0001] The invention belongs to the technical field of building waterproof materials, in particular to a two-component polyurethane waterproof coating structure. Background technique [0002] With the advancement of science and technology and the development of the chemical building materials industry in our country, polyurethane waterproof coatings have also developed rapidly. Among the waterproof coatings in our country, the most widely used and the largest amount is polyurethane waterproof coating. Because traditional asphalt waterproof coatings and tar-based polyurethane waterproof coatings contain a large amount of volatile substances such as naphthalene, anthracene, and quinones, they will seriously endanger people's health and cause serious pollution to the environment. With the progress of society and the improvement of people's living standards, environmental protection and health have attracted more attention. Under the environment of rapid develop...
