Abstract

The invention discloses a high temperature-resisting high-hardness waterproof wall coating which comprises portland cement, imvite, cellulose ether, polyoxyethylene polyoxypropylene glycol ethers, KH-560, polyquaternary amine modified sulfonated polyether amine-hyperbranched polypyrrolone copolymer, 1,3-dibromopropane, graphene oxide and chitosan. The invention also discloses a preparation method for the high temperature-resisting high-hardness waterproof wall coating.

Description

technical field [0001] The invention belongs to the technical field of coatings, and more specifically, the invention relates to a high-temperature-resistant high-hardness waterproof wall coating and a preparation method thereof. Background technique [0002] With the progress of society, the development of science and technology, and the continuous enhancement of people's awareness of environmental protection, people's requirements for house decoration are getting higher and higher, not only needing to be beautiful and beautiful, but also requiring environmental protection and health. However, most of the interior and exterior decoration materials on the market are organic materials or organic-inorganic composite materials, which contain a large amount of volatile organic compounds (VOC), such as formaldehyde, benzene and other toxic substances, and are easy to fade, yellow, mold, and fall off after being exposed to moisture. And there are problems of easy aging and flammab...
