specific Embodiment approach 1

[0013] Specific embodiment one: a kind of peroxysilane coupling agent of this embodiment is 1,1-diperoxy tert-butyl, 4-oxycyclohexyl trimethoxysilane (PTMOSi-1), its structural formula is:

[0014]

specific Embodiment approach 2

[0015] Specific embodiment two: the preparation method of the described peroxysilane coupling agent of specific embodiment one, carry out according to the following steps:

[0016] 1. According to the molar ratio of tert-butanol hydroperoxide and 4-hydroxycyclohexanone as 1: (0.1~10.0), put tert-butanol hydroperoxide and 4-hydroxycyclohexanone into the reaction kettle and stir, the temperature Control it at -10°C~20°C, then add concentrated sulfuric acid, stir for 4~50h, the obtained product is washed with water, filtered out, and then dried at low temperature to obtain 1,1-diperoxy-tert-butyl, 4-hydroxyl Cyclohexane;

[0017] 2. According to the molar ratio of 1,1-diperoxy-tert-butyl, 4-hydroxycyclohexane and tetramethoxysilane as 1:(0.2~5.0), the 1,1-diperoxide obtained in step 1 Add tert-butyl, 4-hydroxycyclohexane and tetramethoxysilane into the reaction kettle, add toluene as solvent at the same time, stir and react at the temperature of -10°C to 50°C for 3 to 48 hours, ...

specific Embodiment approach 3

[0018] Specific embodiment 3: The difference between this embodiment and specific embodiment 2 is that the molar ratio of tert-butanol hydroperoxide to 4-hydroxycyclohexanone in step 1 is 1: (1-5). Others are the same as in the second embodiment.

Abstract

A peroxysilane coupling agent and a preparation method thereof, the invention relates to a silane coupling agent and a preparation method thereof. The invention aims to solve the technical problems of cumbersome process and high cost of grafting high polymer on the surface of existing inorganic materials. The peroxysilane coupling agent of the present invention is 1,1-diperoxy tert-butyl, 4-oxycyclohexyl trimethoxysilane, and its structural formula is: Preparation method: tert-butyl hydroperoxide and 4-hydroxyl Cyclohexanone is put into a reaction kettle, and concentrated sulfuric acid is added at a temperature of -10°C to 20°C, and the reaction is stirred to obtain 1,1-diperoxy-tert-butyl, 4-hydroxycyclohexane; then 1 , 1-diperoxy-tert-butyl, 4-hydroxycyclohexane and tetramethoxysilane are stirred and reacted at -10°C to 50°C to obtain a peroxysilane coupling agent. The peroxysilane coupling agent has the functions of initiator and coupling agent at the same time, and can be used in the reaction of grafting high polymer on the surface of inorganic materials.

Description

technical field [0001] The invention relates to a silane coupling agent and a preparation method thereof. Background technique [0002] As a "bridge" to improve the interface between inorganic materials and organic materials, coupling agents are used more and more widely. Among them, the silane coupling agent is the one with the largest amount and the most varieties at present. Silane coupling agent is a silicone monomer with two or more different reactive groups in the molecule, which can chemically bond with organic and inorganic materials to increase the adhesion of the two materials. The general structural formula of silane coupling agent is RSiX 3 , where X represents an alkoxy group that can be hydrolyzed, such as halogen, alkoxy, acyloxy, etc.; R represents an active functional group that has affinity or reactivity with polymer molecules, such as oxygen, mercapto, vinyl, epoxy, etc. group, amido group, aminopropyl group, etc. [0003] In recent years, with the dev...
