Title:
P-N-B FLAME-RETARDANT PBS PLASTIC AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/060560
Kind Code:
A1
Abstract:
A P-N-B and PBS composite flame-retardant plastic, which is formed by sequentially mixing and extruding a P-N-B flame retardant and polybutylene succinate as raw materials, wherein the P-N-B flame retardant is obtained by reacting a phosphonitrilic chloride trimer and 2-aminoethyl diphenylborinate as main raw materials. The P-N-B flame retardant is prepared by the reaction of the phosphonitrilic chloride trimer and 2-aminoethyl diphenylborinate, and is applied to the preparation of a PBS plastic product, thus both good mechanical properties and excellent flame retardant properties can be effectively achieved, the problems, such as smoke production and burning droplets, of the material can be greatly reduced, effectively improving the fire escape rate, and the P-N-B and PBS composite flame-retardant plastic is suitable for popularization for application.
