Abstract

The invention provides a flame-retardant polypropylene material and a preparation method, and aims to improve the flame-retardant system and improve the flame retardation of the flame-retardant polypropylene material on the premise of keeping and improving the mechanical property of PP. The invention adopts the technical scheme that the flame-retardant polypropylene material comprises the following components in part by mass: 60 to 70 parts of polypropylene, 0.3 to 0.5 part of antioxidant, 22 to 28 parts of halogen-free intumescent flame retardant, 2 to 6 parts of grafted polypropylene, 0.5 to 0.7 part of lubricant and 12 to 17 parts of filler. Experiments show that the mechanical property of the flame-retardant polypropylene material is improved and the flame retardation is excellent.

Description

technical field [0001] The invention relates to plastic materials, in particular to a flame-retardant polypropylene material and a preparation method. Background technique [0002] Polypropylene is a thermoplastic with light specific gravity, high surface hardness, high elasticity, good heat resistance, chemical stability, and good insulation. It is widely used in many fields of production and life. It is the most promising general-purpose plastic engineering One of the most popular plastic varieties. However, PP is extremely flammable, with a limiting oxygen index (LOI) of only 17.4 to 18.5, and severe melting and dripping during combustion, which is easy to spread flames and cause fires, making its application unsafe. This limits the application of PP in electronics, communication equipment, household appliances, automotive appliances, building materials and other industries. In order to meet the requirements of flame retardancy, PP must be modified. Improving the flame ...
