Problems solved by technology

[0003] Traditional anti-corrosion coatings usually use organic solvents such as benzene, ketones, and esters, which have certain pungent odors and biological toxicity. However, resins that use water as a solvent need to add a large amount of water due to the defects of water, such as high surface tension and poor volatility. Co-solvent and other issues, there are many defects
In addition, pure organic polymer resins have defects in mechanical properties, heat resistance and aging resistance in the use of coatings.

Abstract

The invention discloses alcohol-soluble organic-inorganic hybrid resin and a preparation method thereof. The alcohol-soluble organic-inorganic hybrid resin is prepared from an organic phase componentand an inorganic phase component; the inorganic phase component is prepared from the following components in percentage by mass: 30-50 wt% of tetraethoxysilane, 1-5 wt% of gamma-glycidoxypropyltrimethoxysilane, 0.65-18 wt% of deionized water, 30-50 wt% of absolute ethyl alcohol and 0.2-0.5 wt% of acetic acid; and the organic phase component is prepared from the following components in percentage by mass: 50-70 wt% of an acrylate monomer mixture, 1-5 wt% of an initiator, 0.5-2 wt% of a chain transfer agent and 25-45 wt% of propylene glycol methyl ether acetate. According to the invention, absolute ethyl alcohol with low toxicity is used as a solvent, so that harm to human bodies is small. In addition, zinc powder functional fillers are added into the prepared alcohol-soluble organic-inorganic hybrid resin, so that the prepared alcohol-soluble organic-inorganic hybrid resin can be widely applied to the fields of high temperature resistance or heavy corrosion resistance.

Description

technical field [0001] The invention relates to the field of anticorrosion coatings, in particular to an alcohol-soluble organic-inorganic hybrid resin and a preparation method thereof. Background technique [0002] Anti-corrosion is to take various means to protect metal objects that are easy to rust, so as to achieve the purpose of prolonging their service life. There are many kinds of anti-corrosion paint, which can be generally divided into: epoxy anti-corrosion paint, polyurethane anti-corrosion paint, acrylic anti-corrosion paint, inorganic anti-corrosion paint, perchlorethylene anti-corrosion paint, chlorinated rubber anti-corrosion paint, high chlorinated polyethylene anti-corrosion paint. It can be used under harsh conditions, and has good durability and weather resistance. It can be used for more than 10 years or 15 years under harsh conditions such as oceans and underground, even in acid, alkali, salt and solvent media, and in Under certain temperature conditions...
