Embodiment Construction

[0032] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0033] Jute fiber composite board is composed of jute fiber and polypropylene fiber. The proportion of fibers used in the two materials is: jute fiber 45%, polypropylene fiber 55%. The jute long fiber bundles are cut into 80mm fibers by cutting machine.

[0034] Composite hemp board preparation process such as figure 1 As shown, the required fibers are firstly pretreated in proportion to make the fibers achieve preliminary opening and mixing effects, and the initially mixed fibers are transported to the opener through the mixing disc through the air flow pipeline for further opening treatment. The bin opener is fully mixed, and after the required mixing effect is achieved, the uniformly mixed fiber layer is fed to the carding machine for carding, and the fiber layer after carding by th...

Abstract

The present invention relates to a method for preparing a long vegetable fiber composite material, a long vegetable fiber composite board and purpose thereof. Jute fiber and polypropylene fiber are mixed according to certain proportionality and are implemented with an opening treatment, so as to reach a mixing effect required by products, then carding to form nets by a carding machine, and folding on a net placing machine according to gram weight of product requirement; the outputted fiber net is then needled into a fiber felt by a needle machine, and is thermal pressed and molded by a roll squeezer to obtain the jute fibre composite material sheet material. The technical scheme of the invention shortens the technological process, improves the production efficiency, and protects environment and reduces the cost.

Description

technical field [0001] The invention belongs to the technical field of automobile polymer materials, and relates to a preparation method of hemp fiber composite material, and also relates to a hemp fiber composite board and its application. Background technique [0002] At present, green environmental protection has been mentioned in the sustainable development strategy worldwide. Actively producing green, natural and easily degradable fibers is an inevitable requirement for reducing environmental pollution and rationally utilizing resources. As far as the automotive field is concerned, with the With the awakening of "ecological awareness", people pay more and more attention to environmental protection and health, and the requirements for automobiles such as environmental protection, light weight, fuel consumption reduction, and cost reduction are also getting higher and higher. The growing role of natural fibers in the manufacture of automotive components as thermal insulat...
