Abstract

The invention discloses a high-filling high-heat distortion temperature polypropylene composite material, which is prepared from the following raw materials in percentage by weight: 30 to 70 percent of co-polypropylene, 5 to 10 percent of powder polypropylene, 10 to 50 percent of talcpowder, 0.5 to 1.5 percent of composite antioxidant, 0.1 to 0.5 percent of nucleating agent, 0.1 to 1 percent of processing aid and 0 to 20 percent of elastomer, wherein the composite antioxidant is a mixture of an antioxidant with multipolar functional group and a common antioxidant; and the functionality of theantioxidant with the polar functional group is more than or equal to 3. A method for preparing the composite material comprises the following steps of: mixing the power polypropylene, the elastomer, the talcpowder, the nucleating agent and partial processing aid to form talcpowder masterbatches; and uniformly mixing the talcpowder masterbatches and the rest components, and performing melt extrusion and granulation. The polypropylene composite material disclosed by the invention has good mechanical properties, also has higher heat distortion temperature, and is suitable for manufacturing automotive interior and exterior parts, parts of air conditioner and the like.

Description

technical field [0001] The invention belongs to the technical field of modified materials, and in particular relates to a high-filling and high-heat-distortion-temperature polypropylene composite material and a preparation method thereof, which are mainly used in the manufacture of interior and exterior trim parts of automobiles, air conditioners and other components. Background technique [0002] Polypropylene (PP) is a thermoplastic synthetic resin with excellent performance. It has the advantages of small specific gravity, non-toxicity, easy processing, anti-disturbance warp and good electrical insulation. and so on have a wide range of applications. However, polypropylene also has some shortcomings, such as large molding shrinkage, low-temperature brittleness, insufficient wear resistance, and low heat distortion temperature. Many parts, such as automobile engines and air conditioners, have high requirements on the heat resistance of materials. If the heat distortion te...
