Abstract

The present invention discloses a bromine base fire retardation agent and a preparation method thereof. The bromine base fire retardation agent comprises, by weight, 20-27% of decabromodiphenyl oxide, 7-19% of 2,2-bis(bromomethyl)propane-1,3-diol, 5-11% of ammonium nitrate, 8-11% of magnesium sulfate, 2-5% of oxalic acid, the balance of urea. Compared with the bromine base fire retardation agent in the prior art, the bromine base fire retardation agent of the invention has good fire retardation and good practicality, and the required addition amount is less and the effect is excellent during use in the actual production.

Description

technical field [0001] The invention belongs to the field of flame retardants, in particular to a brominated flame retardant and a preparation method thereof. Background technique [0002] The production and use of brominated flame retardants has a history of more than 30 years. At present, there are more than 70 kinds of brominated flame retardants, the most important of which are decabromodiphenyl ether (DBDPO), tetrabromobisphenol A ( TBBPA) and hexabromocyclododecane (HBCD), among which the output of the former two accounts for about 50% of the brominated flame retardants. Brominated flame retardants have high flame retardant efficiency, wide application area, good heat resistance, and excellent hydrolytic stability. accept. Their decomposition temperature is mostly around (200-300) ° C, which matches the decomposition temperature of various polymers, so brominated flame retardants can prevent combustion at the best time when the gas phase and condensation are the same...
