Abstract

A pasty copolymer resin of chloroethylene-vinyl acetate is prepared through under the protection of surfactant dispersing the chloroethylene monomer and vinyl acetate monomer in water by use of high-speed pump or slowly stirring to form fine liquid drips, polymerizing at 40-65 deg.C under the action of trigger system to obtain copolymer latex with 0.1-2.0 microns glanularity, and spray drying. Its advantages are better paste-forming performance and good low-temp plasticity.

Description

technical field

[0001] The invention belongs to the technical field of macromolecule chemical industry, in particular to prepare vinyl chloride-vinyl acetate copolymerization paste resin through microsuspension or emulsion copolymerization method. Background technique

[0002] At present, there are polyvinyl chloride (PVC) paste resin products produced in China. The main methods of preparation are emulsion polymerization and microsuspension polymerization. The primary particle size of the product is 0.1-2.0 μm, the shape is spherical, and it is applied in the form of a paste (plasticized paste) with a plasticizer. The plasticized paste only needs to be heated. It can be made into solid products after plasticizing, and the plasticizing temperature is 140-230°C. Its main application areas are as follows: (1) Coating products: clothing and outerwear, gloves, raincoats, automotive interior decoration, wallpaper, floor leather, luggage bags, interior decoration of trains and bus...
