Abstract

The invention discloses a polypropylene composite material, which is composed of polypropylene, high-density polyethylene, polyolefin elastomer, talcum powder, antioxidant, light stabilizer, inorganic surface modifier, organic surface modifier, lubricating prepared from agent and toner, wherein the inorganic surface modifier is a modified montmorillonite surface modifier, and the organic surface modifier is a modified polytetrafluoroethylene surface modifier. After the polypropylene composite material in the invention is treated with the organic surface modifier and the inorganic surface modifier, while maintaining the normal appearance of the workpiece, the composite material has excellent resistance to gasoline solvents. The invention also discloses a preparation method of the polypropylene composite material and the application of the polypropylene composite material in automobile interior and exterior decoration parts.

Description

technical field [0001] The invention belongs to the field of polymer materials, and in particular relates to a polypropylene composite material and its preparation method and application. Background technique [0002] Polypropylene material is widely used in various fields due to its low cost, abundant raw materials, large output, and good mechanical balance. At present, polypropylene materials have been widely used in interior and exterior materials of automobiles. However, the solvent resistance of conventional polypropylene materials is poor. When used in the automotive field, they are often exposed to different types of solvents. The surface of the parts exposed to solvents will undergo significant changes such as softening and stickiness, which will affect the use of the parts. [0003] Mainstream automobile OEMs have clear experimental requirements for this kind of problem, and the usual test item is color fastness to solvent rubbing. The solvent resistance performan...
