Environmental-friendly thermal insulation waterproof nanometer water-based coating

Abstract

The invention relates to an environmental-friendly thermal insulation waterproof nanometer water-based coating, which comprises the following substances in parts by weight: 20-50 parts of ethylene-vinyl acetate copolymer EVA and acrylic copolymer emulsion, 10-30 parts of kieselguhr, 10-30 parts of nanometer SiO2, 0.1-1 part of pH value regulator and 5-20 parts of water. The coating, provided by the invention, has the advantages of strong weather resistance and adhesion force, good environmental-friendly property, good thermal insulation water resistance, and wide application range, and can be used in multiple fields.

Description

technical field [0001] The invention relates to a water-based paint, in particular to an environment-friendly heat-insulating and waterproof nanometer water-based paint. Background technique [0002] With the development of economy, aerospace, automobile, military industry, petroleum and petrochemical, metallurgy, electric power, construction and other system technologies are constantly innovating, and are used in chimney flue, high temperature steam pipe, heat exchanger, high temperature furnace, high temperature desulfurization equipment, The thermal insulation requirements for pyrolysis equipment, engine parts, exhaust pipes, buildings, high-temperature tools and high-temperature equipment are becoming more and more stringent, so the requirements for the performance of metal materials are getting higher and higher. In order to work in a harsh corrosive environment, it must also have properties such as thin layer, anti-vibration, anti-fatigue, anti-temperature sudden chang...

[0002] With the development of economy, aerospace, automobile, military industry, petroleum and petrochemical, metallurgy, electric power, construction and other system technologies are constantly innovating, and are used in chimney flue, high temperature steam pipe, heat exchanger, high temperature furnace, high temperature desulfurization equipment, The thermal insulation requirements for pyrolysis equipment, engine parts, exhaust pipes, buildings, high-temperature tools and high-temperature equipment are becoming more and more stringent, so the requirements for the performance of metal materials are getting higher and higher. In order to work in a harsh corrosive environment, it must also have properties such as thin layer, anti-vibration, anti-fatigue, anti-temperature sudden change, and anti-scouring properties. Traditional heat insulation materials have been difficult to meet the requirements of use. Development, high temperature thermal insulation coatings came into being
