Abstract

An antistatic high-temperature resistant acrylate pressure-sensitive adhesive, and a preparation method and application thereof are disclosed. The pressure-sensitive adhesive includes a component (A)and a component (B). The component (A) is prepared from, by weight, 4-8% of a hard monomer, 18-28% of a soft monomer, 2-8% of a functional monomer, 1-3% of a heat-resistant monomer, 65% of a solvent,and an initiator the weight of which is 0.1-0.5% of the total weight of the hard monomer, the soft monomer, the functional monomer and the heat-resistant monomer. The component (B) includes one or more selected from a curing agent, an auxiliary agent and an antistatic agent. The weight of the curing agent, the weight of the auxiliary agent and the weight of the antistatic agent account for 2-5%, 0.1-1% and 0.1-1% respectively of the total weight of the component (A). The pressure-sensitive adhesive has good heat resistance and good antistatic performance and is free of softening, yellowing andresidual adhesive at high temperature.

Description

technical field [0001] The invention relates to the field of pressure-sensitive adhesives, in particular to an antistatic high-temperature-resistant acrylate pressure-sensitive adhesive, a preparation method and application 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 bon...
