Abstract

The invention relates to a halogenated organic silicate ester flame-retardant plasticizer, namely a methyl silicate tri(2-chloroethyl) ester compound, and a preparation method thereof. The structure of the compound is shown as CH3Si(OCH2CH2Cl)3. The preparation method comprises the following steps of: introducing undersurface epoxy ethane with a certain molar ratio into methyl trichlorosilane under the cooling condition; reacting at the constant temperature for a certain period of time after the introduction; and removing excessive epoxy ethane and a small quantity of low-boiling-point substances by distilling to obtain colorless liquid methyl silicate tri(2-chloroethyl) ester. The methyl silicate tri(2-chloroethyl) ester has high flame retardance, high plasticity, a simple production process, small equipment investment and low cost, is environment-friendly and is easy for realizing industrial production.

Description

technical field

[0001] The invention relates to a halogenated organosilicate flame retardant plasticizer compound and a preparation method thereof. Specifically relates to a methyl silicate tris (2-chloroethyl) ester compound and a preparation method thereof. Tris(2-chloroethyl)methylsilicate is a silicon-halogen-containing synergistic flame-retardant plasticizer, which is suitable for flame-retardant plasticizing additives of polyvinyl chloride, polyurethane, epoxy resin, unsaturated resin, etc. Background technique

[0002] With the wide application of polymer materials, because of its flammability, it often causes fires and poses a serious threat to people's lives and property, thus promoting the research of flame retardant technology and the rapid development of flame retardant plasticizer industry. Flame retardant plasticizer is a plastic processing aid with flame retardant function and plasticizing effect. It can overcome the problem of making polymer materials more f...
