Title:

REACTIVE PHOSPHORUS-SILICON SYNERGISTIC FLAME RETARDANT, POLYMERIC PHOSPHORUS-SILICON SYNERGISTIC FLAME RETARDANT, PREPARATION METHODS THEREFOR AND APPLICATIONS THEREOF

Document Type and Number:

WIPO Patent Application WO/2022/089459

Kind Code:

A1

Abstract:

Disclosed are a reactive phosphorus-silicon synergistic flame retardant, a polymeric phosphorus-silicon synergistic flame retardant, preparation methods therefor and applications thereof. The reactive phosphorus-silicon synergistic flame retardant can react with a reactive group in an added system to obtain a required flame-retardant component product. A polymeric flame retardant can be obtained by means of self-polymerization or copolymerization of the reactive phosphorus-silicon synergistic flame retardant, to directly provide an excellent flame-retardant additive for a polymer material. The reactive phosphorus-silicon synergistic flame retardant and the polymeric phosphorus-silicon synergistic flame retardant provided by the present application are low in addition amount in the system and good in flame retardant property, such that the added system is free of dripping during combustion and low in smoke generation amount. The preparation processes of the flame retardants provided by the present application are simple, resource-saving, and green and environment-friendly.
