Abstract

The invention discloses a polypropylene material suitable for manufacturing automobile interior decorations, a preparation method and a use thereof. The polypropylene material suitable for manufacturing automobile interior decorations is prepared from the following raw materials in parts by weight: 1-3 parts of lubricant, 0.5-2.5 parts of dispersant, 1-5 parts of antioxidant, 2-6 parts of inorganic filler, 3-8 parts of glass fiber and 30-80 parts of polypropylene. The preparation method is simple, the cost is low, the rigidity, stability, formability, mechanical property, anti-aging property and the like of the polypropylene material are improved by the mutual cooperation of the components; at the same time, it also has good yellowing resistance, and the obtained polypropylene material suitable for manufacturing automobile interior decorations can be used for preparing automobile bumpers, rear-view mirrors, lamps, automobile roofs, glove boxes, automobile seat back plates, door platesand other automobile decorations, and the balance between impact strength and mechanical properties can be obtained.

Description

technical field [0001] The invention relates to the field of plastics, in particular to a polypropylene material suitable for manufacturing automotive interior parts and its preparation method and application. Background technique [0002] As my country has become the world's largest automobile production and consumption country, automobile lightweight, safety, environmental protection and energy saving have become the only way for its industrial adjustment. In the prior art, some parts of automobiles that require high wear resistance are usually made of polyoxymethylene or glass fiber reinforced nylon engineering plastics with polytetrafluoroethylene, but the prices of these two materials Expensive. With the increasing cost pressure of the automobile manufacturing industry, the market urgently needs to find a low-cost wear-resistant material to replace polyoxymethylene and nylon. [0003] Polypropylene, referred to as PP, is a thermoplastic polypropylene produced by the po...
