Novel building roof waterproof coating

Abstract

The invention discloses a novel building roof waterproof coating which is prepared by the following raw materials by weight: 2.5-5 parts of polyurethane acrylate, 3.5-7 parts of toluene diisocyanate, 1.2-2.7 parts of ethylene glycol phenylate, 0.8-2.4 parts of iron oxide red, 1.2-3.4 parts of polyoxyethylene fatty acid amide, 2.2-3.8 parts of polyoxyethylene-polyoxypropylene block copolymer, 3.5-4 parts of 2,4-dimethyl p-toluidine, 0.8-1.6 parts of azobisisoheptonitril, and 1.2-2.3 parts of phenolic resin. The coating of the invention is rich in flexibility, can adapt to a certain degree of vibration and displacement of building structures, can form a homogeneous and waterproof sealing layer which is seamless as one body, and forms no stress point; the coating of the invention has good bonding strength, has good adhesive performance with base materials such as wood, metal materials, tiles, various stone, cement and the like, and can seal loose substrates, special-shaped parts, and prepouring joints.

AI Technical Summary

Benefits of technology

This technology allows for flexible construction that forms strong layers without any cracks or damage from external factors like impact force or changes caused by temperature differences between different materials used together. It also provides an effective way to prevent leakage due to imperfections during installation.

Problems solved by technology

This patented technical solution for creating strong but durable films with good adherence properties against moist environments such as rain or snow can be used in building construction materials like cement blocks.
