Chemically modified chlorinated polyether resin and anticorrosive coating thereof

Abstract

The invention relates to a chemically modified chlorinated polyether resin and an anticorrosive coating thereof. The chemically modified chlorinated polyether resin is modified by chemical reaction between a monomer containing carbon-carbon double bond and a chlorinated polyether resin, with viscosity of 1000-2500MPa.s. The use level of the reactants in the chemical reaction is as follows based onpart by weight: 1 part of chlorinated polyether resin, 2-4 parts of monomer containing carbon-carbon double bond, 3-5 parts of xylene and 0.03-0.05 part of mixed initiator; wherein, the monomer containing carbon-carbon double bond is one or more of ethyl acrylate, butyl acrylate, acrylic acid 2-ethylhexyl ester, methyl methacrylate, butyl methacrylate and styrene; the mixed initiator is the mixture of benzoperoxide and azodiisobutyronitrile, with weight ratio of 0.5-3 to 1. The anticorrosive coating with the chemically modified chlorinated polyether resin of the invention and the chlorinatedpolyether resin as base materials has obviously better storage stability, coating film gloss, mechanical property and various anticorrosion properties than the physically blended and modified chlorinated polyether resin coating.

Description

Chemically modified chloroether resin and its anticorrosion coating technical field The invention relates to a chemically modified chloroether resin and its anticorrosion paint. Background technique Chlorine ether resin is a copolymer of 75% vinyl chloride and 25% vinyl isobutyl ether (vinyl chloride-vinyl isobutyl ether), and its performance is relatively stable. The anti-corrosion coating made of this base material has certain properties such as ozone resistance, light aging resistance, and atmospheric aging resistance, and has good anti-corrosion properties against water, sea water, salt water, chemical atmosphere, acid, alkali, salt, etc. In order to obtain better comprehensive properties of coatings and meet the requirements of engineering construction, it is necessary to modify the chloroether resin. At present, the method of physically mixing other resins and / or plasticizers is usually used to modify the chloroether resin. Other resins used for physical blending i...

Problems solved by technology

However, the compatibility and stability of chloroether resins and other resins that are physically blended still need to be improved, and the coating film of anti-corrosion coatings formed by this physically blended modified chloroether resins has a high performance in terms of durability, corrosion resistance, and corrosion resistance. etc., can not meet the requirements of long-term protection
