Strength-toughness waterproof coating applied in indoor decoration and manufacturing method thereof

Abstract

The invention discloses a strength-toughness waterproof coating applied in indoor decoration and a manufacturing method thereof. The waterproof coating comprises two parts, one part is a viscous suspension obtained from heating concentration of a suspension composed of acidified modified methacryloxy light curing resin, chitin micro-powder, lignin decomposed polysaccharide, trace useless organic matters and minerals and water, wherein the acidified modified methacryloxy light curing resin is obtained from lobster shells, methacryloxy light curing resin and sawdust under the combined action oflysase, ligninase and dilute hydrochloric acid; the other part is a hydroxylated bisphenol A epoxy acrylate and hydroxylated 2-hydroxyl-1,2-diphenyl ethyl ketone aqueous solution obtained by dissolving bisphenol A epoxy acrylate and 2-hydroxy-1,2-diphenyl acetone in absolute ethyl alcohol, then undergoing a reaction with sodium hydroxide and then carrying out heating evaporation to remove ethyl alcohol. The strong-tough waterproof coating has the advantages of wide source, detailed and easily realized manufacturing process, quick effect, lasting effect, green and environmental protection, no pollution, high strength, good toughness and self-hydrophobicity.

Description

technical field [0001] The invention relates to the field of environmental protection coatings, in particular to a tough waterproof coating applied to interior decoration and a manufacturing method thereof. Background technique [0002] Environmentally friendly coatings in the prior art mainly refer to synthetic polymer waterproof materials, which are waterproof coating materials formulated with synthetic rubber or contract resin as the main film-forming substance and other auxiliary materials. At present, the ones that are widely used in the market are specially developed for home decoration, using high-quality modified acrylate emulsion as the base material, adding various additives and filling materials, and scientifically processing to become a single-component high-performance waterproof material. However, because it is a one-component coating, it has poor flexibility and difficult quality control, which leads to high production threshold, difficult quality control, and...

Problems solved by technology

However, because it is a one-component coating, it has poor flexibility and difficult quality control, which leads to high production threshold, difficult quality control, and limited self-curing ability

Existing technologies, including waterproof coatings in patented technologies, generally pursue their waterproof performance, but the chemical stability and other mechanical properties (such as scratch resistance and corrosion resistance) of the coating itself are poor.
