Abstract

The invention relates to a high temperature solvent resistant acrylate pressure sensitive adhesive which comprises the following components in parts by weight: 150-250 parts of 2-ethylhexyl acrylate, 50-100 parts of butyl acrylate, 3-10 parts of acrylic acid, 3-10 parts of hydroxyethyl acrylate, 10-20 parts of vinyl acetate, 15-35 parts of bornyl isoacrylate, 0.5-3 parts of azobisisobutyronitrile, 0.3-2 parts of N-hydroxymethyl acrylamide and 400-600 parts of ethyl acetate. The mechanical property, high temperature resistance and weather resistance of the emulsion type acrylate pressure sensitive adhesive are improved, so that the application range of the emulsion type acrylate pressure sensitive adhesive is widened, and the pressure sensitive adhesive has the characteristics of high viscidity, high temperature resistance, damp-heat aging resistance and low cost.

Description

technical field [0001] The invention belongs to the technical field of pressure-sensitive adhesives, and relates to a preparation method and application of a high-temperature-resistant solvent-type acrylate pressure-sensitive adhesive. Background technique [0002] At present, the adhesive tape used on the microwave oven door is mainly acrylic pressure-sensitive adhesive, and its main purpose is to protect the door body, and has the functions of explosion-proof and microwave radiation-proof. The main requirement is high temperature resistance. Ordinary microwave oven door stickers usually require a high temperature resistance of 180°C, while high-end microwave ovens with a high-power barbecue function require a high temperature resistance of 210°C. Therefore, one development direction of solvent-based acrylate pressure-sensitive adhesives is high temperature resistance. [0003] Patent CN 102516892 A relates to solvent-based acrylate pressure-sensitive adhesives for high-t...
