Problems solved by technology

[0004] Chinese patents CN102516665A, CN101781424A and CN102417660A respectively disclose a PP automobile bumper material, but its components are completely derived from petroleum-based materials, and there are deficiencies in low carbon, green environmental protection and price
Chinese patents CN101747560B and CN102827425A respectively report a modified polypropylene for automobiles filled with talcum powder. Although the impact resistance of polypropylene is improved and its cost is reduced, the advantage of low density of polypropylene is weakened.
Although plant fibers are used in this technical solution, the compatibility between the components is poor, and its mechanical properties are not good
[0006] The existing polymer materials for automobiles have the following disadvantages: 1. The components of polymer materials for automobiles are almost all derived from petrochemical resources, which is not conducive to low-carbon, green and sustainable development
3. As a typical non-polar crystalline polymer material, polypropylene has the problems of poor dimensional stability, poor colorability, difficulty in painting and poor color stability

Abstract

The invention discloses a plant fiber-reinforced polypropylene composite material and a preparation method thereof, and an application of the plant fiber-reinforced polypropylene composite material in preparation of automobile components. The composite material is prepared from the following raw materials in percentage by weight: 40%-77% of polypropylene, 20%-40% of a plant fiber, 1%-10% of vegetable oil, 1%-10% of a flexibilizer and 0.1%-5% of an assistant, wherein the plant fibers and the vegetable oil are from renewable biomass, and conform to the requirements of low-carbon, environment-friendly and sustained economic development. In addition, a low-density biomass material is capable of further promoting light weight of automobiles, and is of great significance in energy conservation and emission reduction. The plant fiber-reinforced polypropylene composite material for automobiles can be prepared by extrusion once, so that the method is simple, easy to operate and suitable for industrialized production.

Description

technical field [0001] The invention relates to the field of polypropylene composite materials, in particular to a plant fiber-reinforced polypropylene composite material and its preparation method and application in the preparation of automobile parts. Background technique [0002] In order to solve the challenges brought by "energy shortage" and "environmental pollution" to the global economy and people's living environment, and to promote the progress of automobile products, protect the environment, promote energy conservation and sustainable development, automobile energy saving and emission reduction are more and more popular among people. focus on. In recent years, the development of new material modification technology has promoted the miniaturization and light weight of automobiles, and has become another important new way to promote energy saving and emission reduction of automobiles. Developed countries in the automobile industry have taken the amount of plastics ...
