Abstract

The invention relates to a visbreaking adhesive tape, in particular to an adhesive composition, an adhesion-reducing adhesive tape applied to optical filter cutting and a preparation method of the adhesion-reducing adhesive tape. In order to solve the problem that an existing adhesion-reducing adhesive tape is not easy to peel off after an optical filter is cut, the invention provides an adhesivecomposition and an adhesion-reducing adhesive tape applied to optical filter cutting. The adhesive composition comprises 100 parts by mass of a (meth) acrylate copolymer, 30 parts by mass of urethaneacrylate oligomer containing 10 unsaturated double-bond functional groups, 5.0-10.0 parts of polyfunctional acrylate monomer containing 6 unsaturated double-bond functional groups, 1.5 parts of a curing agent and 1.5 parts of a photoinitiator. The adhesive composition forms an adhesive layer after being cured, the prepared adhesion-reducing adhesive tape is subjected to UV dispergation after an optical filter is cut, the stripping force is low after UV dispergation, the adhesion-reducing adhesive tape is easily separated from the optical filter, and the problem that an existing adhesion-reducing adhesive tape is not easy to peel off after an optical filter is cut is solved.

Description

technical field [0001] The invention relates to an adhesive tape, in particular to an adhesive composition and an adhesive tape applied to cut filters. Background technique [0002] Camera modules are an important part of mobile devices such as smartphones or tablets, and are developing in the direction of miniaturization, integration and functionality. In order to eliminate the impact of infrared light on solid-state electronic devices CCD (Charge Coupled Device, which is a charge-coupled device image sensor) or CMOS (Complementary Metal Oxide Semiconductor, originally meant to refer to complementary metal oxide semiconductors, a large-scale application in the manufacture of integrated circuit chips The raw material is a readable and writable RAM chip on the motherboard of the microcomputer, which is used to save the hardware configuration of the current system and the user's setting of certain parameters) and other imaging effects, usually by adding an infrared cut filter ...
