Abstract

The invention relates to an anaerobic adhesive for photovoltaic resin board cutting and a preparation method and application thereof. The anaerobic adhesive comprises anaerobic adhesive liquid and a surface accelerant. According to the invention, vinyl resin in the anaerobic adhesive is used for improving the strength of the anaerobic adhesive after curing; epoxy resin and polyester resin are usedfor improving the adhesive strength of the adhesive; after active components are uniformly mixed, the viscosity of an anaerobic agent is improved so as to reduce the fluidity; then, tert-butyl peroxybenzoate, N,N-dimethylaniline and o-benzoylsulfonimide, which are taken as an initiator and an accelerant, are added in the anaerobic adhesive, and a polymerization inhibitor and a coupling agent areused as optimizers; the anaerobic adhesive for photovoltaic resin board cutting, prepared by the preparation method provided by the invention, has the advantages of high curing strength, high adhesive-removing speed and the like; next, the anaerobic adhesive is stable in storage performance, and after coating and curing, a gap is not formed between the anaerobic adhesive and a photovoltaic resin board or the anaerobic adhesive does not break away from the photovoltaic resin board; and in addition, after removing the adhesive by soaking in acidic liquid, the anaerobic adhesive is not adhered tothe photovoltaic resin board.

Description

technical field [0001] The invention relates to an anaerobic adhesive, in particular to an anaerobic adhesive for cutting photovoltaic resin panels and its preparation method and application. Background technique [0002] With the development of science and technology, the photovoltaic industry has gradually replaced some of the functions of petrochemical energy; the raw materials used most in the photovoltaic industry are polycrystalline silicon wafers and monocrystalline silicon wafers; and the cutting and production of monocrystalline silicon wafers and polycrystalline The most important link. During the cutting process of crystal silicon wafers, adhesives are needed to fix the crystal holder, glass and ingot, so adhesives are indispensable auxiliary materials in the cutting process of vigilant silicon wafers. [0003] A kind of epoxy resin adhesive for photovoltaic cutting and its preparation method disclosed in the Chinese patent whose application publication number is...
