Embodiment 1

[0011] Step 1: Mixing

[0012] Each take 10kg of brown silk and hemp fiber, 40kg of polyester fiber and 50kg of polypropylene fiber and mix evenly to make a mixture;

[0013] Step 2: laying the net

[0014] Spread the mixture made in the first step to make an intermediate substrate, and then lay non-woven fabric and PP film on the upper and lower sides of the intermediate substrate to make a composite substrate semi-finished product

[0015] The third step: blanking, heating and pressing and molding

[0016] The composite substrate semi-finished product is blanked, heated and pressurized and molded to form a composite substrate finished product.

Embodiment 2

[0018] Respectively get brown silk and hemp fiber 30kg, polyester fiber 30kg and polypropylene fiber 40kg and mix homogeneously to make compound, all the other are the same as Example 1.

Embodiment 3

[0020] Respectively get brown silk and hemp fiber 25kg, polyester fiber 35kg and polypropylene fiber 40kg and mix homogeneously to make compound, all the other are the same as Example 1.

Abstract

The environment protecting thermoplastic composite palm and hemp fiber base material is used mainly in automobile inside decoration parts. It consists of middle base plate, facing non-woven fabric and bottom PP film compounded together, and features that the middle base plate is prepared with palm and hemp fiber in 10-30 wt%, dacron fiber in 30-40 wt% and polypropylene fiber in 40-50 wt% and through mixing and netting. The present invention is non-toxic, environment friendly, light, moisture absorbent and low in cost.

Description

Technical field: [0001] The invention relates to a composite substrate. In particular, it relates to an environment-friendly thermoplastic natural palm hemp fiber automotive interior trim composite base material. It is mainly used as a composite base material for automotive interior parts. It can also be used as a base material for furniture, building materials, and packaging. It belongs to the technical field of composite panels. Background technique: [0002] With the rapid development of the automotive industry, the quality requirements for automotive interior parts are also getting higher and higher. The quality of an interior part depends critically on its composite substrate. The current composite substrates for automotive interior parts are usually PU board (polyurethane board) or PP wood powder board. PU boards are used to produce car roofs. PP wood powder board is used in the production of automobile door inner panels, etc. Its advantages are good formability...
