Description

technical field [0001] The invention relates to a pressure-sensitive adhesive, more specifically to a liquid rubber type temperature-resistant pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive, the abbreviation of pressure-sensitive adhesive, is a type of adhesive that is sensitive to pressure. It is mainly used to prepare pressure-sensitive tapes. Its function is to make the tape have pressure-sensitive adhesive properties. According to the composition of the main resin, pressure-sensitive adhesives can be divided into two types: rubber type and resin type. The rubber type can be divided into natural rubber and synthetic rubber; the resin type mainly includes acrylic, silicone and polyurethane. [0003] Among them, rubber-type pressure-sensitive adhesives, also known as elastomer-type pressure-sensitive adhesives, are widely used in various fields because of their good bonding strength and low environmen...
