specific Embodiment approach 1

[0013] Specific embodiment one: a peroxysilane coupling agent of this embodiment is 1,1-diperoxy tert-butyl, 4-hydroxycyclohexyl 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 stirring tank, 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, an...

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

The invention relates to peroxy-silane coupling agents and a preparation method of the peroxy-silane coupling agents in order to resolve the technical problems that an existing process of surface grafting of high polymer on the surface of inorganic materials is complex and high in cost. The peroxy-silane coupling agents are 1,1-di-tert-butyl peroxide,4-hydroxyl cyclohexyl trimethoxy silane, and please see the structural formula in the specifications. The preparation method includes the steps that hydrogen peroxide tertiary butanol and 4- hydroxyl cyclohexanone are put into a reaction still, concentrated sulfuric acid is added at the temperature of minus 10-20 DEG C and stirred for reaction, and 1,1-di-tert-butyl peroxide,4- hydroxyl cyclohexane is obtained; the 1,1-di-tert-butyl peroxide,4- hydroxyl cyclohexane and quadri-methoxy silane are stirred at the temperature of minus 10-50 DEG C for reaction, and the peroxy-silane coupling agents are obtained. The peroxy-silane coupling agents both have the functions of initiator and coupling agents, and can be used for the reaction of surface grafting of 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...
