Abstract

The invention discloses a preparation method of emulsion type adhesion promoter for polyolefin plastics. The emulsion type adhesion promoter for polyolefin plastics is obtained through dispersing and emulsifying chlorinated polyolefin, organic solvent, emulsifying agent and water under a proper condition. A small quantity of organic solvent facilitates dispersing chlorinated polyolefin resin in the emulsion preparation process; and the swelling role of organic solvent to polyolefine also ensures good adhesive attraction of a coating layer to a substrate when the emulsion is formed into a film. Compared with a similar solvent based product, the emulsion type polyolefine adhesion promoter lowers the use amount of the organic solvent and has the adhesion property which can be compared with the similar solvent based product. The emulsion type adhesion promoter for polyolefin plastics has simple preparation process, low price, favorable construction property, small environment pressure andwide market prospect.

Description

technical field

[0001] The invention relates to a preparation method of an emulsion-type adhesion promoter, in particular to a preparation method of an emulsion-type adhesion promoter for polyolefin plastics. Background technique

[0002] Polyolefins can generally refer to alpha-olefins such as ethylene, propylene, 1-butene, 1-pentene, 1-octene and homopolymers or copolymers of certain cycloolefins (the present invention mainly relates to polyethylene, polypropylene, Copolymers of ethylene and propylene), which have good properties such as low price, easy processing, and corrosion resistance, are widely used as product processing materials in industries such as automobiles, home appliances, and construction. In order to make the product beautiful and durable, it is often necessary to coat polyolefin plastics. However, polyolefin plastics have low surface energy and high crystallinity, resulting in poor solubility and wettability, and poor adhesion to coatings. In order to ...
