Problems solved by technology

[0003] However, polypropylene material has the disadvantage of low elastic modulus, which is difficult to meet the application requirements in industry
The main modification method is to add talcum powder, which has an obvious effect on improving the rigidity of polypropylene, but at the same time increases the density of polypropylene, which is not conducive to lightweight requirements in some application fields

Abstract

The invention discloses a polypropylene composite and a preparation method thereof and belongs to a polypropylene material. The polypropylene composite is prepared by compounding the following components: 80-95 parts of polypropylene, 5-20 parts of inorganic powder, 0.02-0.2 part of coupling agent and 0.1-0.3 part of antioxidant. The preparation method comprises the steps: (1) drying the inorganicpowder; (2) adding polypropylene, the inorganic powder, the coupling agent and the antioxidant into a mixer to mix until polypropylene, the inorganic powder, the coupling agent and the antioxidant are sufficiently mixed; and (3) adding the mixture into an extruder to carry out melt blending and extrusion, cooling and pelletizing to obtain the polypropylene composite with low density and high modulus. The polypropylene composite disclosed by the invention is capable of keeping the low density of polypropylene while improving the rigidity and strength of polypropylene.

Description

technical field [0001] The invention relates to a polypropylene material, in particular to a low-density and high-modulus polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene has a wide range of sources, its relative density is small, and its processing performance is excellent. Moreover, polypropylene has good heat resistance and can be used for a long time under the condition of 100-120 °C. In addition, polypropylene also has excellent chemical corrosion resistance, electrical insulation and low dielectric rate, good rigidity and folding resistance, and its products are non-toxic, tasteless, and glossy. Therefore, polypropylene is widely used in automobiles, home appliances, machinery, packaging and other fields. [0003] However, polypropylene material has the disadvantage of low elastic modulus, which makes it difficult to meet the application requirements in industry. The main modification method is to add talc...
