Abstract

The invention provides a carboxyl-containing viscosity-reducing glue composition as well as a preparation method and application thereof. The carboxyl-containing viscosity-reducing adhesive composition comprises the following components in parts by weight: 89-96 parts of a carboxyl-containing unsaturated acrylate adhesive, 1-5 parts of a photoinitiator and 1-3 parts of a curing agent, the carboxyl-containing unsaturated acrylate adhesive comprises an acrylate adhesive containing carboxyl and a carbon-carbon double bond; the carboxyl-containing unsaturated acrylate adhesive comprises the following raw materials in parts by weight: 45-55 parts of a carboxyl-containing acrylate polymer and 4-10 parts of an unsaturated monomer containing an epoxy group; according to the carboxyl-containing viscosity-reducing glue composition, UV active monomers or low polymers do not need to be added, through cooperative use of the specific carboxyl-containing unsaturated acrylate adhesive, the photoinitiator and the curing agent, the peeling strength is high before UV illumination, and direct crosslinking curing can be achieved after UV illumination, so that the viscosity-reducing effect is achieved, and the carboxyl-containing viscosity-reducing glue composition is easy to fall off, free of residual glue and good in high temperature resistance.

Description

Technical field [0001] The present invention belongs to the technical field of chip protective film, and more particularly to a carboxyl-containing susceptor composition and a method and use thereof. Background technique [0002] The UV mounted tape has a high adhesive force before the UV irradiation, the attachment is good, after separation, after a short time UV irradiation, the adhesive force is greatly reduced, easy to tear without residual rubber, widely used In the field of semiconductor wafer cutting, mobile glass surface protective layer, fixed, protective and bonding the action in the manufacturing process of the semiconductor wafer, but in some steps have passed high temperature steps, general The UV mounted tape is difficult to achieve this process. [0003] At present, the formulation of UV split gel on the market is mostly mixed with hydroxyl unsaturated acrylate polymers, multifunctional acrylate low polymers, photoinitiators and curing agents, but in this method sy...
