Abstract

The invention provides a flame treatment free polypropylene material for an automobile bumper and a preparation method of the polypropylene material, wherein the polypropylene material comprises the following components in parts by weight: 60-80 parts of polypropylene, 5-10 parts of an elastomer, 10-30 parts of a filler, 2-5parts of a polar additive, 0-0.3 part of an antioxidant and 0-0.5 part ofa lubricant. According to the preparation method, the surface polarity of the polypropylene material is increased by adding a certain proportion of the polar additive, thereby realizing the flame-freespraying process.

Description

technical field [0001] The invention relates to material modification, in particular to a flame-free treated polypropylene material for automobile bumpers and a preparation method thereof. Background technique [0002] At present, the front and rear bumpers of domestic automobiles generally use polypropylene (PP) materials. Polypropylene material has high melting point, heat resistance, low density (currently the lightest one among general-purpose plastics), and high corrosion resistance. However, because polypropylene is a non-polar material with low surface energy, it has poor compatibility with most polymers, is not easy to infiltrate, bond and print, has poor coating performance, and has low bonding strength with paint. Therefore, ordinary polypropylene The material is not suitable for use in car bumpers. In order to improve the paint adhesion of polypropylene, surface treatment is usually carried out before painting. First, the dust and oil stains adsorbed on the surf...
