Abstract

The invention discloses epoxy resin acrylic ester copolymerization pressure-sensitive adhesive. The epoxy resin acrylic ester copolymerization pressure-sensitive adhesive is prepared from the following components in parts by weight: 10 to 40 parts of hard monomer, 25 to 70 parts of soft monomer, 10 to 50 parts of epoxy resin, 0.2 to 1.8 part of composite emulsifier, 0.2 to 2.5 parts of ammonium sulfate, 7 to 15 parts of isocyanate and an adjusting amount of acid-binding agent and dispersing medium. The monomer and the epoxy resin of the epoxy resin acrylic ester copolymerization pressure-sensitive adhesive have excellent compatibility, emulsification, initiation and crosslinking of the system are ideal, the triethylamine acid-binding agent is excessive relative to an initiator, the reaction can be promoted effectively, and a terminal point can be indicated. The pressure-sensitive adhesive has excellent adhesive strength, permanent adhesion and high bonding strength with a matrix, and still has excellent peeling strength under the thermal action.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to an epoxy resin acrylate copolymerized pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is a kind of adhesive that is sensitive to pressure. It does not need to add other additives or heat. It only needs to apply a small pressure to be firmly bonded to the substrate to be adhered. It will have an impact on the surface of the base material, and its characteristics are that it is easy to stick, easy to remove, peeling without damage, and the adhesive layer will not dry up in a long period of time, so the pressure-sensitive adhesive is also called self-adhesive. Pressure-sensitive adhesive products are used in various fields such as packaging, automobiles, transportation, communications, electrical appliances, building materials, machinery, aviation, light industry, and hygiene. Because of their convenie...
