Abstract

The invention discloses a method to make silane coupler that contains cyan and secondary amino group. The molecular structure is (R1O)3-xSiR2xR3NHR4NHy(C2H4CN)z that is made up from the reaction of 1-2mol acrylonitrile and 1mol amino silane that has the molecular of (R1O)3-xSiR2xR3NHR4NH2. Comparing to traditional amino silane coupler, it has good restoring stability could be make into other coupler. The mechanical property and strength of bond to the base material would be greatly improved.

Description

technical field

[0001] The present invention relates to a silane coupling agent containing cyano group and secondary amino group and its preparation method and application Background technique

[0002] Silane coupling agent is a kind of low-molecular-weight organosilicon compound with special structure. It also has reactive groups that can combine with inorganic materials and organic materials. The materials are coupled together, increasing the bond strength of the interfacial layer. Therefore, the mechanical properties and hydrolysis resistance of composite materials can be improved by pretreating fillers and glass fibers with silane coupling agents or directly doping silane coupling agents into resins, fillers, and fibers, or directly silane coupling The agent is added to the adhesive or used as a primer to improve the bonding strength of the adhesive to the substrate. Work in this area has been reported as early as the 1950s. Amino silane coupling agents have been wide...
