Abstract

The invention discloses an optical solidifying cyanacrylate binder, which comprises the following parts: 65. 00-90.00% alpha-cyanacrylate, 5. 00-30.00% (methyl) acrylate, 0.10-4. 00% adhesion accelerant, 0.01-2. 00% stabilizer and 0.10-5. 00% optical initiator. the invention is fit for binding metal, plastic, rubber, wood, polyolefin and fluorine product, which possesses excellent binding effect.

Description

technical field [0001] The present invention relates to an ester copolymer binder, especially an acrylate copolymer; wherein it also relates to its raw material cyanoacrylate monomer. In addition, the present invention also relates to the fact that the adhesive can adopt dual curing technologies of light curing and moisture curing. Background technique [0002] When the α-cyanoacrylate adhesive is applied to the surface of the adherend, it can quickly polymerize and solidify in the presence of traces of water, and it can be used in a very short period of time for certain inert materials such as polyethylene and Teflon. Almost all materials can be bonded. Due to such a superior property, α-cyanopropylene carboxylate adhesive is widely used as a room temperature curing one-component instant adhesive for bonding metal, plastic, rubber, wood, etc. Generally, cyanoacrylate adhesives do not cure well when the surface is exposed to air. They rely on the surface moisture of the ma...
