Abstract

The invention relates to the technical field of high polymer materials, and concretely relates to a high-strength flame-retardant PP composite material and a preparation method thereof. The high-strength flame-retardant PP composite material is prepared from, by weight, 80 to 110 parts of PP, 16 to 24 parts of polyethylene, 10 to 15 parts of an ethylene-vinyl acetate copolymer, 6 to 12 parts of aninorganic filler, 5 to 10 parts of a glass fiber, 4 to 7 parts of a cross-linking agent, 0.1 to 1.5 parts of an antioxidant and 9 to 15 parts of a flame retardant. The flame retardance is improved byadding the flame retardant to the high-strength flame-retardant PP composite material, the prepared PP composite material has good impact strength and tensile strength, the preparation method is simple and efficient to operate, convenient to control and beneficial to industrial production, and the prepared product is stable in quality.

Description

technical field [0001] The invention relates to the technical field of polymer materials, in particular to a high-strength flame-retardant PP composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a thermoplastic synthetic resin with excellent performance. It is a colorless and translucent thermoplastic lightweight general-purpose plastic. It has good chemical resistance, heat resistance, electrical insulation and good high wear-resistant processing performance, etc. advantage. With the development of science and technology and the progress of society, polypropylene is widely used in machinery, automobiles, electronic appliances, construction, textiles, packaging and many other fields. Pay attention to. Existing flame retardant polypropylene is basically added with flame retardant, which has a certain flame retardant effect, but too much flame retardant is often easy to cause a greater impact on the mechanical properties an...
