Problems solved by technology

[0003] Although the glass fiber reinforced polypropylene composite material has many advantages, because the molecular chain of polypropylene itself is non-polar, the surface resistivity reaches 10 when used. 15 ~10 18 order of magnitude (Ω), it is easy to generate static electricity in the application, which limits the application range of polypropylene to a large extent

Abstract

The invention belongs to the technical field of high polymer materials and relates to a polypropylene composite material and a preparation method thereof. The material is prepared from the following components in parts by weight: 100 parts of polypropylene, 5-25 parts of glass fiber, 5-30 parts of zinc oxide whiskers, 0.3-1.5 parts of antioxidant, 0.2-1.5 parts of lubricating agent, 0.1-1 part of coupling agent and 0.1-1 part of nucleating agent. The zinc oxide whiskers and the glass fibers are compounded according to a certain ratio, so that the mechanical performance of the polypropylene is improved, and the antistatic performance of the polypropylene is enhanced. In addition, the zinc oxide whiskers are added into the system, so that the surface smoothness and dimensional stability of the products can be effectively improved, and the application range of the polypropylene modified material is widened. Moreover, by utilizing a simple preparation process, the polypropylene composite material with excellent mechanical performance and a certain antistatic performance is obtained.

Description

technical field [0001] The invention belongs to the technical field of polymer materials, and relates to a polypropylene composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) is a polymer material with low cost, excellent performance and wide application. In the research and development of general plastic engineering, polypropylene is one of the materials with the most development potential. By strengthening polypropylene Modification is higher than commonly used engineering plastics such as polyester and polyamide in terms of cost performance. Among them, glass fiber reinforced polypropylene composite materials are widely used in engineering fields. [0003] Although the glass fiber reinforced polypropylene composite material has many advantages, because the molecular chain of polypropylene itself is non-polar, the surface resistivity reaches 10 when used. 15 ~10 18 Order of magnitude (Ω), it is easy to generate static elect...
