Abstract

The invention relates to a chlorinated polypropylene / acrylate hybrid water dispersion, a preparation method and application thereof. The preparation method can realize good compatibility between chlorinated polypropylene and acrylic resin, and the obtained water dispersion Good storage stability, excellent adhesion and water resistance on PP and other substrates, can be used for PP substrate primers to achieve good adhesion between PP substrates and topcoats, and can also be used with water-based isocyanate curing agents. Use topcoats that give excellent adhesion to PP substrates.

Description

technical field [0001] The invention relates to the field of acrylate emulsions, in particular to a chlorinated polypropylene / acrylate hybrid aqueous dispersion and a preparation method and application thereof. [0002] technical background [0003] Polypropylene material has excellent properties such as light weight, good toughness, non-toxic and tasteless, and low price. At the same time, it has good molding and processing performance, and is widely used in the fields of automobiles, electronics and toys. However, due to its own characteristics of polypropylene material, such as non-polar material, high crystallinity, low surface energy, etc., it is difficult to wet and adhere to its surface. At present, PP water (a solvent-based chlorinated polypropylene solution with a content of about 20%) is usually used to enhance the adhesion ability of the polypropylene material surface and improve the compatibility with other resins. However, a large amount of organic solvents will...
