Abstract

The invention discloses a heat conduction type polyacrylate pressure-sensitive adhesive and a preparation method thereof. A polyacrylate emulsion is prepared from components in parts by weight as follows: 40-58 parts of lauryl acrylate, 50-70 parts of ethyl methacrylate, 24-36 parts of 3-methacryloxypropyltrimethoxysilane, 10-15 parts of N-tert-octylacrylamide, 6-9 parts of N-acryloylmorpholine, 6-8 parts of methyl myristate alpha-sodium sulfonate, 9-14 parts of sodium polyoxyethylene lauryl ether carboxylate, 30-50 parts of itaconic acid and 32-45 parts of acrylic acid. The heat conduction type polyacrylate pressure-sensitive adhesive has good heat conduction performance, can transfer heat rapidly, has good initial adhesion and strong holding power, can keep stable performance for a long time and is non-toxic, environmentally friendly and wider in application range.

Description

technical field [0001] The invention relates to the field of textile auxiliaries, in particular to a heat-conductive polyacrylate pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesives refer to pressure-sensitive adhesives that can be firmly bonded to the adhered object without resorting to solvents, heating or light, and are not easily damaged when peeled off, only by applying light finger pressure during use. Features that don't dry out for a longer period of time. Most of the pressure-sensitive adhesives are made into pressure-sensitive adhesive products such as tapes and films. Pressure-sensitive adhesive products are widely used in the fields of automobiles, packaging, building materials, electronic appliances, daily necessities, and medical and health care. They can play various connection functions such as binding, sealing, insulating, protecting, and fixing. is constantly expanding. Polyacrylate pre...
