AI Technical Summary

Problems solved by technology

Although the latter has acceptable performance in a broad sense, its inherent characteristics are that it is easy to age or dry under the combined effects of sunlight, air and water, and it is also not resistant to alkali corrosion. The effect is not long-lasting, which is an important reason why the roof of our country is prone to water leakage accidents after a long time
[0003] The waterproof and anti-cracking coatings in the prior art are limited by the lack of technical field and practical experience, and the waterproof and anti-drying coatings in a complete sense have not really appeared. , green and environmental protection, long-lasting waterproof and anti-drying coating

Abstract

The invention discloses a waterproof anti-dry-cracking coating material for roofs, and a manufacturing method thereof. The waterproof anti-dry-cracking coating material comprises, by weight, 100 partsof an acrylic resin, 160-175 parts of cement powder with the grade of 52.5R, and 15-18 parts of an anti-dry-cracking component, wherein the anti-dry-cracking component is alkalized fibers and enzymolysis saccharide-based organic matters prepared from sawdust and green Dendrocalamus latiflorus Munro. According to the present invention, the waterproof anti-dry-cracking coating material has functions of water immersion resistance, alkali corrosion resistance, dry cracking resistance, environmental protection and long-lasting effect.

Description

technical field [0001] The invention relates to the field of environmental protection coatings, in particular to a waterproof and anti-cracking coating applied to roofs and a manufacturing method thereof. Background technique [0002] There are two main types of waterproof materials used for roofs on the market today: one is polyurethane waterproof coatings. Such materials are generally made of polyurethane and coal tar as raw materials. 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 sale uses asphalt instead of coal tar as a raw material. However, when using this kind of coating, it is generally diluted with organic solvents such as toluene and xylene, so it also contains toxicity; the other type is polymer cement-based waterproof coating. It is composed of a variety of water-based polymer emulsions and high-quality cement mixed with various additives. The flexibil...
