Abstract

The invention relates to a 2-(3-broMopropoxy)-2(2-dicholoropropoxy) silane compound used as a fire retardant and the preparation method thereof. The structural formula of the compound is shown in the specification, wherein when R1equals to H, R2 equals to CH2C1; when R1 equals to CH2C1, R2 equals to H. The preparation method comprises the following steps: dripping dichloropropanol of which the mole is the same as that of silicon tetrachloride into silicon tetrachloride organic solution, reacting for 1 hour at the temperature of 35 DEG C, then adding tribromophenol of which the mole doubles that of silicon tetrachloride, reacting for 4-6 hours at the temperature of 65-90 DEG C, dripping dichloropropanol of which the mole is equal to that of silicon tetrachloride, reacting for 5-7 hours at the temperature of 70-95 DEG C, and reducing pressure and distilling to remove solvent to obtain the 2-(3-broMopropoxy)-2(2-dicholoropropoxy) silane compound. The silane compound is an excellent fire retardant plasticizer, has carbon-forming and anti-dripping functions, can be used as fire retardant made of polyvinyl chloride, unsaturated polyester, polyurethane, epoxy resin and the like, and is easy to access in raw material, low in production cost, small in equipment investment, simple in production technology, and easy for large-scale production.

Description

technical field

[0001] The invention relates to a flame retardant bis(tribromophenoxy)bis(dichloropropoxy)silane compound and a preparation method thereof, the compound can be used as polyvinyl chloride, unsaturated polyester, polyurethane and epoxy resin Flame retardant for other materials. 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. Among them, ...
