Abstract

Belonging to the technical field of preparing high thermostable materials by adding specific thermostable components into ordinary eight bromo ether, the invention relates to a preparation method of high thermostable eight bromo ether. The method of the invention employs a composite thermostable auxiliary agent of zine stearate / barium stearate or zine stearate / calcium stearate in a specific amount and a specific proportion, a composite anti-oxidant in a specific amount and a specific proportion, adds a specific kind of coupling agent, and adopts a high-speed mixer for high-speed stirring and blending so as to prepare a high thermostable eight bromo ether material, the 1% weight loss temperature of which is increased by 20-30DEG C.

Description

technical field [0001] The invention relates to a preparation method of highly thermally stabilized octabromoether, which belongs to the technical field of obtaining high thermal stability materials by adding specific stable components to common octabromoether. Background technique [0002] The full name of octabromoether is tetrabromobisphenol A-bis(2,3-dibromopropyl) ether, which is a commonly used brominated flame retardant, which is added to polypropylene, polystyrene and other materials and combined with antimony compounds When used in combination, the material can obtain excellent flame retardant properties. Since octabromoether has a bromine content of more than 67% and a melting point of more than 105°C, it has good compatibility with polyolefin materials. [0003] However, as a flame retardant additive material, the octabromoether molecule contains eight bromine atoms in the aliphatic chain. During the processing of the material, the bromine atom is prone to underg...
