Abstract

The invention discloses a copolymer resin of chloroethylene-isobutyl vinyl ether-glycidyl acrylate and a preparation method thereof. The copolymer resin is obtained by copolymerization of 65-85 mass parts of chloroethylene, 15-30 mass parts of isobutyl vinyl ether and 0.5-5.0% (corresponding to the total mass of chloroethylene and isobutyl vinyl ether) of glycidyl acrylate. The preparation method comprises the following steps: adding the chloroethylene, isobutyl vinyl ether and glycidyl acrylate into aqueous phase containing emulsifier, a water-soluble redox initiation system and pH regulator, and carrying out emulsion polymerization for 3-10 hours at the temperature of 35-60 DEG C. The invention adds glycidyl acrylate into chloric ether resin to improve the heat stability of chloric ether resin and adhesion with metal; and meanwhile, copolymer has uniform composition and has high dissolving speed in solvent, such as sundex and the like.

Description

Vinyl chloride-isobutyl vinyl ether-glycidyl acrylate copolymer resin and preparation method technical field The invention relates to a compound and a preparation method thereof, in particular to a vinyl chloride-isobutyl vinyl ether-glycidyl acrylate copolymer resin and a preparation method thereof. Background technique Vinyl chloride-isobutyl vinyl ether (VC-IBVE) copolymer resin, referred to as chloroether resin, is a kind of binder resin with excellent comprehensive performance for coatings and inks. It can be dissolved in many solvents, including aromatic hydrocarbons commonly used in coating production. and ester solvents; it can be miscible with alkyd resin, acrylic resin, dry oil, tar, asphalt and plasticizer; chlorine ether resin has strong saponification resistance, and because the combined chlorine atoms are very stable, the coating has Water resistance and chemical corrosion resistance, its anti-corrosion ability is 2 to 3 times that of ordinary anti-corrosion ...
