Abstract

The invention discloses a high-performance polyurethane pressure-sensitive adhesive. The polyurethane pressure-sensitive adhesive is prepared from the following raw materials in parts by weight: 70-90 parts of neoprene, 60-80 parts of methyl methacrylate, 60-80 parts of hydroxy terminated polydimethylsiloxane, 30-50 parts of xylene resin, 30-50 parts of polyisocyanate, 20-40 parts of carbon fibers, 20-40 parts of olefine resin, 10-18 parts of azo-compound foaming agent, 10-18 parts of rosin resin, 5-10 parts of triethylamine, 5-10 parts of methylpentynol, 5-10 parts of polybutadiene, 4-8 parts of triethylamine, 1-2 parts of dibutyltin dilaurate and 0.5-1 part of N-hydroxymethyl acrylamide. The preparation method comprises the following steps: S1, weighing 70-90 parts of neoprene, 60-80 parts of methyl methacrylate, 60-80 parts of hydroxy terminated polydimethylsiloxane, 30-50 parts of xylene resin and 30-50 parts of polyisocyanate according to the weight proportion, adding into a reaction kettle, heating the reaction kettle to 60-80 DEG C, and sufficiently stirring. The high-performance polyurethane pressure-sensitive adhesive is simple in preparation, has good performance and environmental friendliness, and is suitable for large-scale production.

Description

technical field [0001] The invention relates to the technical field of polyurethane pressure-sensitive adhesives, in particular to a high-performance polyurethane pressure-sensitive adhesive. Background technique [0002] Pressure-sensitive adhesives and their products are widely used in the fields of office, packaging, electrical engineering, electrical appliances, etching, paint and home decoration, and are closely related to people's lives. Pressure-sensitive adhesives are used in consumer goods and are used in large quantities in various industries. Ordinary pressure-sensitive tape and label technology is very mature, and its output exceeds demand, but the pressure-sensitive adhesive used in the automotive, electronic industry and other fields requires good cohesion and adhesion. The adhesive layer will not be damaged when the force is cut, and the adhesive force ensures that the pressure-sensitive adhesive has a high peel strength. The balance between the cohesive forc...
