Abstract

The invention discloses a multi-functional building exterior wall environment-friendly nano-coating. The multi-functional building exterior wall environment-friendly nano-coating is prepared from the following components in parts by weight: 20-50 parts of water-based acrylic emulsion, 4-8 parts of butyl acrylate, 1-2 parts of nano TiO2, 1-1.5 parts of pearl mica powder, 0.5-1 part of hollow glass beads, 0.8-1.2 parts of sodium hexametaphosphate, 1.1-1.5 parts of ethoxylated alkylphenol sulfate, 0.5-1 part of propyltrimethoxysilane, 2-3 parts of pH regulator, 2-5 parts of other aids and 10-20 parts of deionized water. The invention further discloses a preparation method of the coating. The coating has the advantages of high coating performance, excellent weather resistance, excellent erosion resistance, high adhesion, non-toxicity and environmental friendliness; moreover, the preparation method is simple, is mild in process conditions, is easy to control, and is low in production cost.

Description

Technical field: [0001] The invention relates to the field of paint preparation, in particular to a multifunctional nanometer building exterior wall environmental protection green paint. Background technique: [0002] At present, my country's building energy consumption accounts for about 28% of the total energy consumption. With the improvement of people's living standards, the proportion of building energy consumption will continue to increase. Architectural coatings are more and more used in buildings because of their advantages of economy, light weight and convenient construction. However, the application environment of architectural coatings, especially exterior wall coatings, is relatively harsh. Ultraviolet rays, heat energy, microorganisms, water, and heavy air pollutants can all cause the aging of polymers in coatings. [0003] The current building exterior wall coatings are mainly manifested in poor anti-aging ability, easy chalking, easy discoloration, poor adhes...
