Abstract

The invention provides an acrylic ester pressure-sensitive adhesive for a window film. Raw materials of the adhesive are composed of an acrylate monomer, a functional monomer, a polymerizing surface active monomer, an initiating agent and an organic solvent, and the adhesive is mainly used as automobile films. A preparation method of the adhesive is adding the acrylate monomer, the functional monomer, the polymerizing surface active monomer and the initiating agent into the solvent slowly to be polymerized. The adhesive is good in anti-static effect and transparent performance, strong in adhesion and high in peel strength.

Description

technical field [0001] The invention relates to an adhesive and a preparation method thereof, in particular to an acrylate pressure-sensitive adhesive for an antistatic window film and a preparation method thereof, which is mainly used as an adhesive for an automobile window film. Background technique [0002] Acrylate pressure-sensitive adhesives are a large category of adhesives. Their polymers have excellent weather resistance, UV resistance, heat resistance, water resistance, chemical resistance, transparent color, and good compatibility with dyes. Therefore, this year get rapid development. At present, the domestic window film [0003] The transparency is not high, the weather resistance and high temperature resistance are poor, and when it is pasted on the car glass plate, the static electricity is relatively large, and it is easy to absorb dust, resulting in impurities on the pasting surface, which affects the appearance and visual effect, and the static electricity ...
