Abstract

The invention discloses a preparation method of a silane coupling agent containing allyl sulfydryl and amino and a usage thereof. The molecular structural formula of the silane coupling agent is (R1O)3-xSiR2xR3(NHR4)yNHz(SHCNH2NHCH2CH=CH2)m. The silane coupling agent is obtained through addition reaction of 1-2 mole allylthiourea and 1 mole silane coupling agent with the molecular formula of (R1O)3-xSiR2xR3(NHR4)yNH2, wherein R1 and R2 are straight chain or branched alkyl of same or different 1-6 carbon atoms, R3 is alkylidene and aryl of 1-6 carbon atoms or aryl alkylidene and alkyl arylene of 6-10 carbon atoms, and R4 is alkylidene of 1-6 carbon atoms, x is 0 or 1, y is 0, 1 or 2, z is 0 or 1, and m is 2-z. Compared with the traditional allyl monomer, the silane coupling agent can be used as active diluent monomer of ultraviolet curing prepolymer, the sulfydryl is contained in the molecule, the inhibition of the oxygen to the ultraviolet curing process can be effectively reduced, the ultraviolet curing speed is improved, the function of the silane coupling agent can be brought into play, and the adhesion function of the coating adhesive and the matrix is improved.

Description

technical field

[0001] The invention relates to a preparation method and application of a silane coupling agent containing allyl mercapto and amino groups. Background technique

[0002] In the UV curing system, the monofunctional monomer mainly acts as a diluent in the system, but it has a great influence on the dissolution of the photoinitiator, the curing rate, the flexibility, hardness, durability of the cured film, and the sensitivity to various substrates. Adhesion, etc. have a great influence. The silane coupling agent is a kind of low-molecular-weight organosilicon compound with a special structure. It also has a reactive group that can combine with inorganic materials and organic materials. It can build a molecular bridge between the interfaces and combine two materials with different properties. Coupled together to improve the bonding strength of the interface layer. Therefore, the mechanical properties and hydrolysis resistance of composite materials can be impro...
