Embodiment 1

[0038] (1) The jute / polypropylene composite material is composed of jute fiber and polypropylene fiber, wherein the mass percentage of the two fibers is: jute fiber 50%, polypropylene fiber 50%, jute fiber and polypropylene fiber are cut by a cutting machine into 60mm chopped fiber; the preparation process of jute / polypropylene composite material is as follows figure 1 As shown, earlier the cut jute fiber and polypropylene fiber are layered successively according to the above-mentioned ratio, and the jute fiber and polypropylene fiber are respectively laid in 20 layers, and the feed is carried out continuously.

[0039] (2) Then send it to the opening machine for one opening, and then send it to the next opening machine through the automatic feeding device for the second opening;

[0040] (3) carding through a carding machine to obtain fluffy and uniformly mixed fibers, each fiber is distributed in a monofilament shape;

[0041] (4) Send the mixed fibers into the web-laying m...

Embodiment 2

[0045] The difference between the present embodiment and Example 1 is: the mass percent of two kinds of fibers is: jute fiber 40%; Polypropylene fiber 60%, jute fiber layer number is 16 layers, and polypropylene fiber is 24 layers, one deck or Multiple layers of jute fibers alternate with one or more layers of polypropylene fibers.

Embodiment 3

[0047] The difference between the present embodiment and Example 1 is: the mass percent of two kinds of fibers is: jute fiber 60%; Polypropylene fiber 40%, jute fiber layer number is 24 layers, and polypropylene fiber is 16 layers, one deck or Multiple layers of jute fibers alternate with one or more layers of polypropylene fibers.

Abstract

The invention belongs to the technical field of composite materials, and relates to a thermoplastic composite material and a preparation method and application thereof. The thermoplastic composite material comprises the following components in percentage by mass: 40-60% of jute fiber and 40-60% of polypropylene fiber. Compared with the prior art, the composite material provided by the invention is environment-friendly and can be degraded naturally; with certain mechanical strength, the composite material can meet the requirement of the automotive trim material for strength; moreover, the composite material also has excellent processing performance and safety performance; and through the invention, the technological flow is shortened, the production efficiency is improved, and more importantly, the green and light automotive trim material is realized. Through the invention, the technological flow is simple, the composite material is easy to manufacture, and the raw materials are widely available and low in price, thereby being favorable for lowering the cost of the composite material; and moreover, a composite board has perfect toughness and does not form an acute-angle section after being broken, thereby being safe and reliable.

Description

technical field [0001] The invention belongs to the technical field of composite materials, and relates to a thermoplastic composite material and its preparation method and application. Background technique [0002] In recent years, with the gradual enhancement of people's awareness of environmental protection and the popularization of sustainable development strategies, the demand for environmentally friendly, degradable and recyclable materials has become more and more vigorous, and the application fields have become wider and wider. Research on this aspect is also getting more and more attention. [0003] As far as the automobile field is concerned, the automobile industry is developing rapidly, the production is changing with each passing day, and the models are constantly being updated. There are also clear requirements for various indicators such as automobile environmental protection, lightweight, fuel consumption reduction, and cost reduction. Existing automotive i...
