Abstract

The invention discloses a special impact-resistant aging-resistant material for a bumper. The special impact-resistant aging-resistant material is prepared from the following raw materials in parts by mass: 88-95 parts of polypropylene, 8-10 parts of ethylene-propylene diene copolymer rubber, 2-3 parts of nanometer rubber, 3-8 parts of a vulcanizing agent, 5-8 parts of a styrene-butadiene copolymer, 0.1-2 parts of an antioxidant 1010, 18-22 parts of a mineral filler and 1-2 parts of a foaming agent. The special material disclosed by the invention has the beneficial effects that the special material has high impact resistance, corrosion resistance, high rigidity and strength and is difficult to age, the used polypropylene is low in density, and the development of automobile lightweight at the present stage is met.

Description

technical field [0001] The invention relates to the technical field of chemical polymer materials, in particular to an impact-resistant and aging-resistant bumper special material. Background technique [0002] In addition to the function of absorbing collision energy and protecting pedestrians, the automobile bumper is mainly used as an exterior decoration, so the requirements for its appearance, impact resistance and corrosion resistance are relatively high. [0003] In recent years, the demand for lightweight automobiles has become higher and higher, and the call for replacing steel with plastic is also increasing. Therefore, the demand for replacing steel with plastic for bumper materials has become increasingly obvious. However, today's bumper materials have relatively high impact and corrosion resistance. Poor, easy to age under wind and sun. Contents of the invention [0004] The purpose of the present invention is to provide a special impact-resistant and aging-re...
