Abstract

The invention relates to a halogen-free flame-retardant PP composite material and a preparation method thereof and belongs to the field of high polymer materials. The halogen-free flame-retardant PP composite material comprises, by weight, 73-83 parts of polypropylene, 6-10 parts of flame retardant, 1.5-2 parts of antioxidant, 3.5-4.5 parts of lubricating agent, 6-8 parts of toughening agent and 1-2 parts of smoke inhibitor, wherein the flame retardant comprises phosphorus-based flame retardant, nitrogen-based flame retardant and inorganic flame retardant, and the weight ratio of the phosphorus-based flame retardant to the nitrogen-based flame retardant to the inorganic flame retardant is (5-15):(25-40):(6-9). The halogen-free flame-retardant PP composite material is good in flame-retardant effect and environmentally friendly.

Description

technical field [0001] The invention relates to a PP composite material and a preparation method thereof, in particular to a halogen-free flame-retardant PP composite material and a preparation method thereof. Background technique [0002] As a general-purpose plastic, polypropylene (PP) has light weight, excellent comprehensive performance, simple production process and wide application. It has become one of the fastest-growing plastics in general-purpose plastics. Although polypropylene has many advantages, due to its low oxygen index and flammability, its application in the fields of electronics, electrical appliances and automobiles has been greatly restricted. In recent years, the country has paid more and more attention to the flame retardancy of plastics, especially for plastic accessories used in household appliances, aviation, automobiles and other industries. [0003] In addition, polypropylene also has defects such as large molding shrinkage, low temperature brit...
