Abstract

The invention discloses a high-temperature-resistant acrylic ester pressure sensitive adhesive. The pressure sensitive adhesive is prepared from raw materials in percentage by weight as follows: 4%-8% of hard monomers, 18%-28% of soft monomers, 2%-8% of functional monomers, 1%-3% of heat-resisting monomers and 65% of a solvent. The pressure sensitive adhesive has higher heat resistance and smaller stripping resistance and does not have residues when cooled to the room temperature after being treated at the high temperature of 180 DEG C, adhesive water does not get yellow under the high temperature condition, and the pressure sensitive adhesive is easy to strip and good in damp heat resistance and well solves the problem of use under high-temperature conditions in all industries. Besides, an actual solution is provided for the fields such as electronic technology, medical treatment, military affairs, aerospace and the like.

Description

technical field [0001] The invention relates to the technical field of adhesives, in particular to a high-temperature-resistant acrylate pressure-sensitive adhesive and a preparation method thereof. Background technique [0002] The full name of pressure-sensitive adhesive is pressure-sensitive adhesive, also commonly known as self-adhesive. Requires a lot of pressure, heat, or the action of a solvent. Therefore, the pressure-sensitive adhesive is called a self-adhesive substance, which is mainly bonded to the surface of the adherend by van der Waals force, and there is no physical and chemical change during the bonding process. Pressure-sensitive adhesive has four main characteristics: ①The bonding process is easy to carry out; ②It is relatively easy to peel off; ③When the pressure-sensitive adhesive is peeled off from the bonding surface, it does not damage the structure of the bonding surface; ④The adhesive layer is very stable, The bonding time is longer, and it will n...
