Problems solved by technology

Since the European Union announced in 1986 that polybrominated diphenyl ether flame retardants produced carcinogen dioxin when burned, the use of halogenated flame retardants has been restricted. Therefore, research and development of high-efficiency halogenated flame retardants to reduce the amount of flame retardants and reduce their toxicity has become an important research direction for halogenated flame retardants

Abstract

The invention relates to a flame retardant tri-(tribromophenoxy) dichloro propoxy silane compound and a preparation method thereof. A structural formula of the compound is as follows as shown in the specification, wherein when R1 is H, R2 is CH2Cl, and when R1 is CH2Cl, R2 is H. The preparation method comprises the steps that equimolar dichloropropanol is dropwise added to an organic solution of silicon tetrachloride, and reacts at 35 DEG C for 1h; three times of mole of tribromphenol is added, and reacts at 80-110 DEG C for 7-9h; a solvent is removed by reduced pressure distillation; and tri-(tribromophenoxy) dichloro propoxy silane is obtained. Tri-(tribromophenoxy) dichloro propoxy silane is an excellent antiflaming plasticizer, has charring and dripping prevention functions, has good compatibility with a high polymer material, and can serve as a flame retardant of polyvinyl chloride, unsaturated polyester, polyurethane, epoxy resin and the like, raw materials of tri-(tribromophenoxy) dichloro propoxy silane are low in cost and easy to obtain, the production cost is low, the equipment investment is low, a production technology is simple, and the scale production is facilitated.

Description

technical field [0001] The invention relates to a flame retardant tris(tribromophenoxy)dichloropropoxysilane compound and a preparation method thereof. The compound can be used as a compound for materials such as polyvinyl chloride, unsaturated polyester, polyurethane and epoxy resin flame retardant. Background technique [0002] With the advancement of science and technology, people's living standards continue to improve, and the awareness of safety and fire prevention continues to increase, which promotes the rapid development of the flame retardant industry. Since the European Union announced in 1986 that polybrominated diphenyl ether flame retardants produced carcinogen dioxin when burned, the use of halogenated flame retardants has been restricted. The research and development of high-efficiency halogenated flame retardants to reduce the amount of flame retardants and reduce their toxicity has become an important research direction of halogenated flame retardants.
