Abstract

The invention discloses a fibrilia-reinforced polypropylene engineering composite, a preparation method thereof and application of the fibrilia-reinforced polypropylene engineering composite to preparation of automobile parts. The composite is prepared from the following raw materials in percentage by weight: 59-80% of polypropylene, 19-30% of fibrilia, 1-5% of epoxy furan, 1-10% of a toughening agent and 0.1-3% of lauroyl peroxide, wherein both the fibrilia and epoxy furan are from renewable biomasses and meet the requirements of low carbon, environment friendliness and sustainable economic development. According to the fibrilia-reinforced polypropylene engineering composite, epoxy furan can reactively improve the interfacial compatibility of polypropylene and fibrilia under the initiating action of lauroyl peroxide, so that the composite is kept to have excellent mechanical property and processability and can be used for preparing the automobile parts. The preparation method of the composite, disclosed by the invention, can be used for preparing the composite through one-step extrusion and is simple, easy to operate and suitable for industrial production.

Description

technical field [0001] The invention relates to the technical field of polypropylene composite materials, in particular to a hemp fiber-reinforced polypropylene engineering composite material, a preparation method thereof, and an application in preparing automobile parts. Background technique [0002] With the "energy shortage" and "air pollution" becoming more and more serious, especially in recent years, the automobile market has developed rapidly, and the energy saving and emission reduction of automobiles has become urgent. In order to promote the progress of automobile products, protect the environment, promote energy conservation and sustainable development, the miniaturization and light weight of automobiles has attracted people's attention. [0003] Developed countries in the automobile industry have taken the amount of plastics and their composite materials as an important indicator to measure the level of modern automobile design and manufacturing technology. As o...
