Acrylic ester pressure sensitive adhesive, pressure sensitive adhesive tape and preparation method of acrylic ester pressure sensitive adhesive

Abstract

The invention relates to the technical field of a pressure sensitive adhesive, in particular to an acrylic ester pressure sensitive adhesive, a pressure sensitive adhesive tape and a preparation method of the acrylic ester pressure sensitive adhesive. The acrylic ester pressure sensitive adhesive provided by the invention is prepared from the following raw materials in parts by weight: 8 to 12 parts of 2-ethylhexyl acrylate, 7 to 10 parts of butyl acrylate, 3 to 4 parts of acrylic acid, 4 to 6 parts of vinyl acetate, 3 to 4.5 parts of methyl methacrylate, 3 to 4 parts of hydroxyethyl methylacrylate, 2 to 3 parts of trimethylolpropane triacrylate, 4 to 6 parts of isoprene rubber with double bonds, 4 to 6 parts of SBS elastomers with double bonds, 45 to 60 parts of solvents and 0.3 to 0.6 part of initiating agents. The acrylic ester pressure sensitive adhesive provided by the invention uses the isoprene rubber and the SBS elastomers for modifying the acrylic ester pressure sensitive adhesive, so that the acrylic ester pressure sensitive adhesive has the advantages of acrylic ester, and also has the electrolyte-resistant and high-temperature-resistant performance of rubber; the defectof poor electrolyte-resistant and high-temperature-resistant performance of the existing acrylic ester pressure sensitive adhesive can be effectively overcome.

Description

technical field [0001] The invention relates to the technical field of pressure-sensitive adhesives, in particular to an acrylate pressure-sensitive adhesive, a pressure-sensitive adhesive tape and a preparation method of the acrylate pressure-sensitive adhesive. Background technique [0002] Traditional acrylate pressure-sensitive adhesives do not contain unsaturated bonds in their molecular structure and have the advantages of aging resistance, light resistance, wide bonding surface, and colorless and transparent. However, the high-temperature resistance of traditional acrylate pressure-sensitive adhesives is not good. The final acrylate pressure-sensitive adhesive can only be used in a short-term environment at 150°C, and the electrolyte resistance of traditional acrylic pressure-sensitive adhesives is not good, and the adhesive layer will be soaked in the electrolyte environment for 3 to 4 hours. Osmotically swells, thereby losing viscosity. Therefore, how to effectivel...
