Abstract

The invention relates to a flame retardant tri-(tribromophenoxy) halogen propoxy silane compound and a preparation method thereof. A structural formula of the compound is as follows as shown in the specification, wherein R is 2-chlorine-1-propyl, 1-chlorine-2-propyl, 3-chlorine-1-propyl, 2-bromine-1-propyl, 1-bromine-2-propyl or 3-bromine-1-propyl. The preparation method comprises the steps that equimolar halogenated propyl alcohol is dropwise added to an organic solution of silicon tetrachloride, and reacts at 30 DEG C for 1h; three times of mole of tribromphenol is added, and reacts at 70-100 DEG C for 6-9h; a solvent is removed by reduced pressure distillation; and tri-(tribromophenoxy) halogen propoxy silane is obtained. Tri-(tribromophenoxy) halogen propoxy silane is good in flame retardancy and plasticity, has charring and dripping prevention functions, has good compatibility with a high polymer material, can serve as a flame retardant of polyvinyl chloride, unsaturated polyester, polyurethane, epoxy resin and the like, raw materials of tri-(tribromophenoxy) halogen propoxy silane are 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)halopropoxysilane compound and a preparation method thereof. The compound can be used as a flame retardant for materials such as polyvinyl chloride, unsaturated polyester, polyurethane and epoxy resin. Fuel. Background technique [0002] With the development of the polymer industry, polymer materials such as plastics, rubber and fibers have gradually been widely used. Because of their flammability, they often cause fires, which pose a serious threat to people's lives and property, thus promoting the development of anti-corrosion The rapid development of flame retardant science and technology and flame retardant industry. Among them, silicon-based flame retardants have excellent properties of suppressing smoke and promoting carbon formation, and have attracted people's attention. However, the high price of silicon-based flame retardants generally limits their application. The development ...
