Anti-corrosion, cold-resistant and self-cleaning coating and preparation method thereof

Abstract

The invention discloses an anti-corrosion, cold-resistant and self-cleaning coating. The anti-corrosion, cold-resistant and self-cleaning coating is characterized by being prepared from the following raw materials in parts by weight: 30-35 parts of an acrylic resin emulsion, 24-28 parts of a polyvinyl chloride resin emulsion, 0.5-1.0 part of zinc naphthenate, 0.3-0.6 part of ethoxy modified trisiloxane, 1-2 parts of ferrocene, 0.4-0.5 part of sodium lignin sulfonate, 2-3 parts of fine-denier mica powder, 2-3 parts of graphite powder, 1-2 parts of stearic acid, 1-2 parts of aluminum oxide powder, 0.1-0.3 part of potassium persulfate, 1-2 parts of gamma-aminopropyl trimethoxysilane, 0.2-0.4 part of a polyacrylate leveling agent, 0.2-0.4 part of white oil, 2-3 parts of n-butyl methacrylate, 3-5 parts of propanediol, 6-9 parts of self-cleaning slurry and 14-20 part of deionized water. The coating disclosed by the invention has excellent water resistance, corrosion resistance, cold resistance, freezing resistance, fire resistance and a self-cleaning effect, the added fine-denier mica powder enhances the fire resistance of the coating, the graphite powder enhances the wear resistance of the coating, propanediol improves the cold resistance and the freezing resistance of the coating, and the coating has the advantages of convenience in taking the raw materials, low cost, a simple operation process and convenience in coating, and is suitable for decoration in a variety of places.

Description

technical field [0001] The invention relates to a coating and a preparation method thereof, in particular to an anti-corrosion and cold-resistant self-cleaning coating and a preparation method thereof. Background technique [0002] The air quality in my country is generally poor and the pollution conditions vary from place to place. Smog, dust, acid rain, etc. often erode our environment, which puts forward higher requirements for the anti-fouling performance of exterior wall coatings. Traditional stain-resistant technologies have certain limitations, which requires us to seek new stain-resistant technologies. Since self-cleaning coatings do not require special maintenance, are low-carbon and environmentally friendly, and have huge market potential, they have become the research of many researchers. development focus. Since photocatalytic self-cleaning glass was developed, Japan and some European countries have successfully developed some corresponding self-cleaning coating...

Problems solved by technology

However, due to some technical problems, photocatalytic self-cleaning coatings cannot be widely used. If these technical problems can be solved, photocatalytic self-cleaning coatings will surely meet the requirements of building exterior wall coatings for stain resistance
