Abstract

The invention discloses a polypropylene composition for spray-free bumpers and a preparation method thereof. The polypropylene composition comprises the following components in percentage by weight: 20-60% of copolymer polypropylene resin, 10-40% of homopolymer polypropylene resin, 10-20% of toughener, 1-4% of antiaging system aid, 1-5% of scratch-resistant agent, 0.1-0.5% of nucleator, 0.5-3% of lubricant, 0.2-0.5% of coupling agent, 1-15% of high-polymer antistatic agent and 1-3% of master batch. The spray-free bumper prepared from the composition has the advantages of favorable washability, favorable permanent antistatic property, favorable long-term aging resistance and low dependence on the environment. The preparation method comprises the following steps: (1) weighing the materials in percentage by weight; (2) stirring and mixing the raw materials to obtain a premix; and (3) carrying out extrusion granulation on the premix to obtain the polypropylene composition. The method has the advantages of simple production technique and low cost.

Description

technical field

[0001] The invention relates to the technical field of material chemistry, in particular to a polypropylene composition for a spray-free bumper and a preparation method thereof. Background technique

[0002] With the continuous development of automobile lightweight requirements, polypropylene composite materials with many advantages such as low cost, good comprehensive mechanical properties, non-toxic, light weight, corrosion resistance, good electrical properties, easy processing, and easy recycling are widely used in Production of auto parts, among which auto bumpers are the most representative parts. Nowadays, the development trend of bumper requires not only protective function, but also decorative function, which should be harmonious and unified with the shape of the car body. The spraying of automobile bumpers can meet the increasingly colorful decorative needs of the automobile industry for bumpers. At the same time, the paint can protect the bumper b...
