Abstract

The invention discloses a room temperature self-crosslinking acrylic ester emulsion. The emulsion comprises deionized water, an initiator, an emulsifier, a vinyl aromatic compound, carboxyl-containing olefin monomers, alkyl acrylate unsaturated monomers of C4-C12, methacrylate unsaturated monomers of C4-C20 and functional monomers. The emulsion is prepared with an emulsion polymerization method by adding a pH regulator, a curing agent and a metallic cross linker. The emulsion has the advantages of high glossiness, good abrasive resistance, water resistance and alcohol resistance, has good dryness under high humidity, can be applied to different coating fields and is also suitable for floor wax formulas of polishing-free wax, spray cleaning, cleaning wax polish and the like. The emulsion can be applied to various rigid base materials such as PVC (Polyvinyl Chloride), boards and composite boards and has good balance between detergent resistance and removability.

Description

technical field

[0001] The present invention relates to a polymer, specifically a room temperature self-crosslinking acrylate emulsion, especially an acrylate emulsion with good wear resistance, water resistance and chemical resistance to vinyl substrates, PVC boards and other substrates . Background technique

[0002] Water-based paint and water-based paint with styrene-acrylic emulsion as the main component have high gloss and color retention, anti-fouling and low cost, so they are the main products in the domestic water-based paint market; , Insufficient wear resistance and chemical resistance are also common problems of styrene-acrylic emulsions. In response to the above problems, many studies have been carried out in recent years to find countermeasures. The first method is to use reactive emulsifiers. However, reactive emulsifiers are expensive and have limited sources; gel slagging is prone to occur when preparing emulsions, so the development is slow. The second ...
