Abstract

The invention belongs to the technical field of anti-adhesive agents and in particular relates to an ultraviolet curable high-performance anti-adhesive agent used in the electronic field. The anti-adhesive agent comprises the following raw materials in parts by weight: 50-60 parts of acrylate modified polysiloxane prepolymer, 15-20 parts of aromatic polyurethane acrylate, 5-10 parts of dimethylaminoethyl acrylate, 1-6 parts of photoinitiators, 0.2-0.5 part of levelling agent, 0.5-1 part of pigment and 20-25 parts of graphene. The anti-adhesive agent has the beneficial effects that the anti-adhesive agent has high performances in various aspects by preparing the acrylate modified polysiloxane prepolymer by adopting dihydroxyl-terminated polysiloxane and gamma-methacryloxypropyltrimethoxysilane as single main bodies; the anti-adhesive agent has the effects of saving energy, simplifying the process and improving the product quality, is beneficial to environmental protection and has an extensive development prospect.

Description

technical field [0001] The invention belongs to the technical field of anti-adhesive agents, in particular to an ultraviolet-curable high-performance anti-adhesive agent used in the electronic field. Background technique [0002] In pressure-sensitive substrates, just as important as pressure-sensitive adhesives are release agents. Among anti-adhesive products, polyorganosiloxane is the most widely used and relatively mature technology. Its development has roughly gone through three stages: solvent-based, emulsion-based and solvent-free (both heat-cured and radiation-cured). The first type consumes a lot of energy and resources, and is extremely dangerous in the production process. Currently, developed countries basically no longer use it; The quality is not stable. The heat-cured solvent-based anti-adhesive agent avoids the defects of the former good general type and has excellent product performance, but it is not suitable for the production requirements of heat-sensiti...
