Embodiment 2

[0025] The technical solution adopted in this embodiment is: it contains the following mass fraction components: 115 parts of vinyl chloride-vinyl acetate copolymer resin, 190 parts of vinyl ester resin, 2 parts of emulsifier sodium lauryl sulfate), catalyst (sulfurized acetic acid Dimethyl ester) 25 parts, modifier (silica sol) 15 parts.

[0026] The K value in the vinyl chloride-vinyl acetate copolymer resin is 70±2, and the vinyl ester content is 4%.

[0027] The preparation method of the present invention is as follows:

[0028] 1. Put the above-mentioned mass fraction of vinyl chloride-vinyl acetate copolymer resin and vinyl ester resin into the reaction kettle, and heat up to 65°C;

[0029] 2. Put the sodium lauryl sulfate of the above mass fraction into the reaction kettle for dissolution, and heat up to 70°C after dissolution;

[0030] 3. At the temperature of step 2, add the modifier dropwise at a constant temperature. After adding half of the silica sol dropwise, s...

Abstract

The invention provides a vinyl chloride-vinyl acetate-vinyl ester ternary polymer water-based resin, relating to the technical field of paints. The vinyl chloride-vinyl acetate-vinyl ester ternary polymer water-based resin comprises the following components in parts by mass: 80-120 parts of vinyl chloride-vinyl acetate copolymer resin, 150-200 parts of vinyl ester resin, 1-2 parts of emulsifier, 20-50 parts of catalyst and 10-30 parts of modifier. The water-based resin can solve the problem of over-rust rust prevention in the water-based paint, can obtain the paint film with the maximum crosslinking density, and can be mixed with most water-based resins on the market to obtain different modified resins.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a vinyl chloride-vinyl acetate-vinyl ester terpolymer water-based resin. Background technique [0002] At present, water-based resins cannot solve all the problems of metal band rust, rust prevention, high penetration and anti-rust, etc. The market is in urgent need of an anti-rust and waterproof resin with high penetration for parts that are difficult to remove rust. Contents of the invention [0003] The purpose of the present invention is to address the defects and deficiencies of the prior art, to provide a rationally designed vinyl chloride-vinyl acetate-vinyl ester terpolymer water-based resin, which can solve the problem of water-based paint with rust and rust prevention, and can achieve The paint film with the highest crosslinking density can be mixed with most of the water-based resins on the market to obtain different modified resins. [0004] In order to achieve th...
