Abstract

The invention discloses acrylate emulsion for plastic base materials. The acrylate emulsion comprises, by weight, 40-60 parts of deionized water, 10-20 parts of butyl acrylate, 25-35 parts of methyl methacrylate, 5-10 parts of styrene, 2-5 parts of hydrophilic unsaturated organic acid, 1-3 parts of functional monomers, 1-3 parts of surfactants, 0.1-1 part of initiators and 1-3 parts of pH (potential of hydrogen) regulators. The invention further provides a method for preparing the acrylate emulsion. The acrylate emulsion and the method have the advantage that the acrylate emulsion prepared bythe aid of the method is excellent in adhesion, solvent resistance, chemical resistance, water resistance, gloss fullness and paint preparation tolerance.

Description

technical field [0001] The invention relates to an acrylate emulsion, in particular to an acrylate emulsion used for plastic substrates with excellent performance and a preparation method thereof. Background technique [0002] With the continuous improvement of people's living standards, the types of coatings used for industrial plastics are also increasing. Coating on plastics can protect and decorate plastic products, improve product performance, and prolong their service life. At present, the plastic coatings widely used in the market are solvent-based. In solvent-based coatings, solvent-based resins play a key and decisive role. In these solvent-based resin systems, the oily system has serious environmental pollution and irritation during the film-forming process. Strong smell, high VOC content, etc., but the two-component system is not conducive to storage stability, and needs to be prepared and used immediately, and has a strong pungent smell, high VOC content. [000...
