Problems solved by technology

The vinyl compounds in this type of adhesive are (meth)acrylate compounds, allyl compounds or vinyl compounds. For special substrates, especially inert substrates and metal oxide substrates such as polytetrafluoroethylene, indium oxide Tin (ITO), etc., but still does not provide sufficient bonding performance

Abstract

The invention discloses a sulfydryl / cyano acrylic ester UV curable adhesive composition, which comprises: 5 to 60 percent of sulfydryl compound which is selected from a sulfydryl alkyl acid ester and alkyl hydrosulfide; 5 to 60 percent of alpha-cyanoacrylate of a formula below; 0 to 60 percent of a prepolymer selected from polyester acrylate prepolymers, epoxy acrylate prepolymers and urethane acrylate prepolymers; 0 to 50 percent of active monomer which is selected from acrylic esters having a mono-functional group, double functional groups and multiple functional groups, allyl compounds and ethenyl compounds; 1 to 10 percent of photoinitiator; and 0 to 10 percent of assistant. The UV curable adhesive composition has a quick curing capability, high adhesive strength and low internal stress; and the obtained cured layer is flexible and can be widely to bond metal, metal oxides, plastics, rubber, glass, polyester and other substrate materials.

Description

technical field The invention relates to a UV photocurable adhesive, in particular to a UV photocurable adhesive comprising a polymerization system of a mercapto compound and a cyanoacrylate. Background technique Since the advent of UV light-curing adhesives in the 1960s, they have achieved rapid development and are widely used in various fields such as medical and health care, aviation, electronics, printing, and optical instruments. The advantages of UV curing adhesives are that the adhesives formulated on demand have very high transmittance, excellent reliability in high temperature and high humidity environments, and good water resistance. The UV curing adhesive is 100% cured to form a film, no solvent volatilization pollution problem, fast curing speed, energy saving, and high production efficiency. Acrylate UV curing adhesives are mixed with various modified acrylate resins (or prepolymers) and acrylate monomers, together with various additives such as adhesion promo...
