Abstract

The invention discloses aminosilyl acrylate and a preparation method thereof, and belongs to the technical field of organic synthesis. Needed aminosilyl acrylate is obtained by stirring amino silane and allyl methacrylate at a temperature of 50-100 DEG C for 3-6 h at presence of a catalyst. Aminosilyl acrylate is a product with a composite function group structure, and contains both acyloxy and amino which mutually coexist. When being applied to a glass fiber impregnating compound, aminosilyl acrylate possesses the strength improved by 20% compared with a silane product separately employing acyloxy and amino, and is obviously improved in strength compared with a singly-employed product containing one group.

Description

technical field [0001] The invention relates to the technical field of organic synthesis, and more specifically relates to an acryloxyaminosilane and a preparation method thereof. Background technique [0002] Silane coupling agent is a kind of organosilicon compound containing two kinds of different chemical properties groups in the molecule at the same time, and its classic product can be used with the general formula YSiX 3 express. In the formula, Y is a non-hydrolyzable group, including alkenyl (mainly vinyl), and a terminal with Cl, NH 2 , SH, epoxy, N 3 , (meth)acryloyloxy, isocyanate and other functional groups of hydrocarbon groups, that is, carbon functional groups; X is a hydrolyzable group. Due to this special structure, there are reactive groups in its molecule that can chemically bond with inorganic materials (such as glass, silica sand, metal, etc.) and chemically bond with organic materials (synthetic resins, etc.). for surface treatment. [0003] The ap...
