Abstract

The invention relates to a peroxide silane coupling agent and its preparation method. Technical problems of single function, and needing of a two step reaction of cladding and polymerization in the use of inorganic particle modified polymers of present silane coupling agents are solved. The peroxide silane coupling agent is a gamma-t-butylperoxypropyltrimethoxy silane coupling agent, and the structural formula of the peroxide silane coupling agent is shown in the specification. The preparation method comprises the following steps: 1, preparing t-butyl hydroperoxide sodium; 2, reacting t-butyl hydroperoxide sodium with 3-chloropropyltrimethoxysilane; 3, washing to remove t-butyl hydroperoxide sodium, sodium chloride and toluene in the obtained product; and 4, extracting by using an n-hexane and ethyl acetate mixed solution as an extractant, carrying out low temperature storage, filtering, and carrying out rotary evaporation to obtain the peroxide silane coupling agent. One end of the coupling agent is a hydrolysable methoxy group, and the other end of the coupling agent is a peroxide group capable of initializing polymerization, so the coupling agent can be used in an inorganic particle surface modification and polymer grafting combined reaction.

Description

technical field [0001] The invention relates to a silane coupling agent and a preparation method thereof. Background technique [0002] The silane coupling agent is made of silicon chloroform (HSiCl 3 ) and unsaturated olefins with reactive groups are added under the catalysis of primary chlorine acid, followed by alcoholysis. In recent years, the application of silane coupling agent, a polymer material additive, to coat inorganic particles has become more and more extensive. By using silane coupling agent, a "molecular bridge" can be built between the interface of inorganic substances and organic substances, and the two Materials with different properties are connected together to improve the performance of composite materials and increase the bonding strength. [0003] At present, the combined application of inorganic particle surface modification and graft polymer has achieved good results in the modification of polymer matrix. In order to graft and polymerize polymers...
