Abstract

The invention relates to a microwave self-repairable polypropylene carbon-based composite material and a preparation method thereof. The polypropylene carbon-based composite material capable of beingself-repaired by microwave is prepared from the following raw materials in parts by weight: 100 parts of polypropylene resin; 0.3-1.2 parts of an antioxidant; 0.3-1.2 parts of a lubricant; 2-5.5 partsof a self-repairing polypropylene master batch; wherein the melt index of the polypropylene resin is 15-55 g / 10 min; wherein the self-repaired polypropylene master batch is obtained by melt extrusionand granulation of a carbon-based material, a silane coupling agent and polypropylene powder through a double-screw extruder; wherein the carbon-based material is at least one of carbon black, carbonnanotubes and graphene. The polypropylene carbon-based composite material with the microwave self-repairing function has excellent self-repairing performance, mechanical performance and processability in a microwave environment, and can be applied to the fields of automobiles and household appliances such as automobile exterior decorations, air conditioner decoration strips and small household appliance exterior decoration structures.

Description

technical field [0001] The invention relates to the technical field of polymer composite materials, in particular to a microwave self-repairable polypropylene-carbon-based composite material and a preparation method thereof. Background technique [0002] Polypropylene (PP) has the advantages of non-toxicity, low odor, low cost, chemical corrosion resistance, and good mechanical properties. It has a very wide range of applications in household appliances, sanitary ware, and electronics. [0003] However, in actual use, polypropylene materials also have many challenges, and the biggest problem is the scratching problem during actual use. Polypropylene is used as a material for a large number of appearance parts in the field of home appliances and automobiles. In the process of production, assembly, transportation and actual use, it will face cleaning, collision, scratching and other processes. These processes will make the surface of polypropylene materials Produces scratches...
