Abstract

The invention relates to a polypropylene microcellular foam composite material and a preparation method thereof. The polypropylene microcellular foam composite material is prepared from, by weight, 85-95 parts of polypropylene, 5-10 parts of carbon fibers and 3-5 parts of foaming masterbatch, wherein the foam masterbatch is prepared from, by weight, 60-70 parts of polyethylene, 20-30 parts of a foaming agent, 3-5parts of a nucleating agent, 0.5-1.5 parts of zinc oxide, 0.5-1 part of a titanate coupling agent NDZ-201, 3-5 parts of PE wax and 0.5-1 part of zinc stearate. According to the polypropylene microcellular foam composite material prepared through the method, the mechanical property is superior, the tensile strength reaches 35.9 MPa, the impact strength reaches 56.1 kJ / m<2>, and the bending modulus reaches 1,620 MPa.

Description

technical field [0001] The invention relates to a polypropylene composite material, in particular to a polypropylene microfoam composite material and a preparation method thereof. Background technique [0002] In the first ten years of the 21st century, the research and development of new energy and new materials in China and other economies around the world have reached a new and higher level. The development of the material field provides a new starting point, a new opportunity, and the requirements for polymers tend to be multi-functional. In the 1980s, the new technology of micro-foaming polymers proposed by the Massachusetts Institute of Technology has significantly improved the performance of materials. At the same time, endowing polymers with excellent new properties has become a new field and new direction for many researchers. Generally speaking, the diameter of microcellular foamed materials is relatively small, about 1 μm to 100 μm. The holes are evenly distribut...
