Abstract

The invention discloses a high-performance jute fiber reinforced polypropylene composite and a prepration method thereof. The high-performance jute fiber reinforced polypropylene composite comprises the following raw materials of, by weight, 20-60 parts of jute fibers, 30-80 parts of polypropylene, 1-10 parts of a compatilizer, 0.5-2 parts of a coupling agent, 0.1-1 part of antioxidants, and 0.2-1 part of lubricants. The polypropylene composite used for vehicles is prepared by adoption of the jute fibers which are low in price, rich in source, high in specific modulus, low in density and small in effect on the environment, the production cost can be lowered, and the composite accords with the development trend of low-weight, environment-friendly and recyclable automobiles; and meanwhile, the natural fibers are treated by adoption of an alkaline solution, the coupling agent and the compatilizer, the hygroscopicity of the jute fibers is reduced, and the bonding force between the jute fibers and polypropylene particles is increased at the same time.

Description

technical field

[0001] The invention belongs to the technical field of fiber composite materials, and relates to a high-performance jute fiber reinforced polypropylene composite material and a preparation method thereof. Background technique

[0002] With the rapid development of the automobile industry and the increasingly severe environmental and energy issues, greening, recyclability, light weight, and low energy consumption have obviously become the themes of the development of automotive materials. As a renewable ecological and environmental protection material, natural fiber is more environmentally friendly than glass fiber and synthetic fiber due to its abundant sources, easy to degrade, low price, and outstanding specific performance. Natural fiber reinforced resin composites are also used as a Green composite materials are getting more and more attention in automotive materials. For example, natural fiber reinforced polypropylene composite materials can be used to m...
