Abstract

The invention relates to a high-toughness polypropylene composite material and a preparation method, belonging to the technical field of polymers. The polypropylene composite product of the present invention comprises the following raw material components in mass percentage: 20-35% polyether ester, 0.3-2.5% nano-Al powder, 0.5-1.0% antioxidant, 0.8-1.3% lubricant, and the balance It is polypropylene; the preparation method of the present invention comprises the following steps: after mixing the raw material components of the polypropylene composite material product, melt spinning is performed to form polypropylene fibers, and then the polypropylene fibers are added to a mold to be heated and pressurized to form, that is Made of polypropylene material. The polypropylene composite material prepared by the invention has higher mechanical properties, especially toughness.

Description

technical field [0001] The invention relates to polymer materials, in particular to a high-toughness polypropylene composite material and a preparation method. Background technique [0002] Polypropylene is a thermoplastic resin produced by the polymerization of propylene. According to the position of the methyl group, it is divided into three types: isotactic polypropylene, atactic polypropylene and syndiotactic polypropylene. Polypropylene is an inexpensive and widely used plastic that can be processed according to the properties of the finished product. It has the advantages of low density, high tensile strength, good chemical resistance, and recyclability, and has many advantages in use. However, the poor toughness of polypropylene, especially low temperature toughness, limits its further application and development. In the prior art, various elastomers are often used to toughen polypropylene, such as ethylene-propylene rubber, ethylene-propylene-diene rubber, and sty...
