Abstract

The invention provides a water-boiling-resistant and flame-retardant polypropylene composite material with a high glow-wire ignition temperature and a preparation method. The water-boiling-resistant and flame-retardant polypropylene composite material with the high glow-wire ignition temperature is composed of the following materials: 72-76 parts of PP resin, 24-28 parts of a nitrogen phosphorus intumescent-type flame retardant, 0.1-0.2 part of an anti-dripping agent, 0.2-0.3 part of an antioxidant, 0.4-0.6 part of a lubricant, and 0.1-0.2 part of a high-efficiency synergist. The flame-retardant polypropylene composite material prepared by the method guarantees the material to pass a UL94 1.6mm-V0 test and achieve high-efficiency flame retardance, and at the same time the flame-retardant polypropylene composite material has performance such as a high glow-wire ignition temperature (875 DEG C, GWIT), water boiling resistance (100 DEG C), precipitation resistance, low smoke and thermal oxygen ageing and discoloring resistance (150 DEG C).

Description

technical field [0001] The invention relates to the technical field of polymers, in particular to a high-glow wire, boiling-resistant and flame-retardant polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene has rich sources of raw materials, cheap prices, easy processing and molding, and excellent product comprehensive performance. It is widely used in automobiles, home appliances, electronic appliances and other industries, and has become the fastest-growing variety of general-purpose resins. However, polypropylene itself is a flammable material, its oxygen index is only 17.4-18.5%, and its char formation rate is low. When it is burned, it will produce molten droplets, which can easily spread flames and cause fires. With the rapid development of social economy, the application of polypropylene has become more and more in-depth, and flame-retardant polypropylene has been greatly developed, especially in the fields of ...
