Abstract

The invention provides a layered-hypophosphite flame-retardant and reinforced polypropylene composite material and a preparation method thereof and relates to the technical field of high polymer materials. The layered-hypophosphite flame-retardant and reinforced polypropylene composite material is prepared by polypropylene resin, layered hypophosphite, a toughening agent, antioxidant, a light stabilizer and a lubricating agent. The preparation method has the advantages that the layered hypophosphite is synthesized through a hydrothermal method, layered hypophosphite nanosheets are well combined with a polypropylene matrix and are evenly distributed in the polypropylene matrix and good in dispersity, influence on material mechanical performance is low, and polypropylene composite material prepared by adding the layered hypophosphite is high in strength and good in thermal stability.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a layered hypophosphite flame-retardant reinforced polypropylene composite material and a preparation method thereof. Background technique [0002] Hypophosphite is a halogen-free and non-toxic flame retardant with excellent performance and environmental friendliness. It has the advantages of high phosphorus content (41.89%), good thermal stability and excellent flame retardant properties. As a new type of flame retardant used in polymer materials, it has received very good results. Wang Yuzhong et al. used the aluminum hypophosphite synthesized by the coprecipitation method in the flame retardant of polystyrene (PS). The results show that adding 25 parts of aluminum hypophosphite can make the composite material reach the UL-94V0 level, and the limiting oxygen index can reach 33.3. %, which can effectively improve the flame retardant properties of PS composites and re...
