Description
Technical field
The invention belongs to new-energy automobile parts process industry technical field, and in particular to a kind of new-energy automobile seat
Backrest composite sheet and preparation method thereof.
Background technology
Required as automobile industry product is light-weighted, client it is also proposed more strict requirements to the weight of product.
The backrest frames overwhelming majority is metal backrest used in the automobile chair of in the market, and manufacturing procedure is complicated, spends more
In terms of man-hour, energy resource consumption, production raw materials for plastics production can save more energy than production raw material metal.Reuse
Cost is smaller, and environment is hardly polluted.The density that it has is small, the linear expansion coefficient of thermoplastic composite compared with
It is small, the advantages such as the shrinkage factor (precision that product size can be improved) during product molding can be reduced and greatly expand composite wood
Metal parts on material use in daily life, gradually alternative metals and timber, such as car.But the intensity of plastics
Specific strength, specific modulus and shock resistance be not strong, and often service life is shorter for the product of preparation.The applying date is November 27 in 2009
Day, the Chinese patent of Application No. 200910199483.1 discloses a kind of car seat back frame of plastic material, described
Skeleton is integrally formed by plastic material, and the skeleton has the shell along its circumferentially extending, the horizontal sentence of the shell
Section is " n " type, and the inner side of the shell of the n tee sections has cellular reinforcement.Although reinforcement is arranged on one
Determine to improve the service life of product in degree, but plastics are also differed very compared with the intensity and impact property of metallic article
Far.
The content of the invention
For defect present in prior art, the invention provides a kind of new-energy automobile backrest composite sheet
And preparation method thereof, new-energy automobile backrest light weight prepared by this method, the stable molding time is short, surfacing and relaxes
Adaptive is high.
To achieve these goals, the technical solution adopted by the present invention is as follows：
The invention provides a kind of new-energy automobile backrest composite sheet, it includes plastic sheet, plastic sheet
Side be compounded with fiber reinforced thermolplastic composite material sheet material, the opposite side of plastic sheet is compounded with resin sheet, resin sheet
Material is made up of matrix resin with fibrous layer, and matrix resin is integrated with fibrous layer, and matrix resin is coated with fibrous layer；Institute
Stating fibrous layer includes warp-wise glass fiber bundle and broadwise carbon glass fibre bundle, and warp-wise glass fiber bundle and broadwise carbon glass fibre bundle are mutual
Intersection is reticulated, and warp-wise glass fiber bundle has 1000~2000 filaments are twisted to form with broadwise carbon glass fibre bundle.
According to above-mentioned new-energy automobile backrest composite sheet, the plastic sheet is polyethylene, polypropylene, gathered
Vinyl chloride, polystyrene, polyformaldehyde, makrolon, polyamide, polymethyl methacrylate, polysulfones, polyphenylene oxide, terephthaldehyde
Sour glycol ester or acrylonitrile-butadiene-styrene (ABS).
According to above-mentioned new-energy automobile backrest composite sheet, the fiber reinforced thermolplastic composite material sheet material
In fiber be glass fibre, carbon fiber, aramid fiber, natural plant fibre or mineral fibres.
According to above-mentioned new-energy automobile backrest composite sheet, the average fiber footpath of the glass fiber is 5
~8 μm, glass fibre list beam diameter is 0.4~1.0mm.
According to above-mentioned new-energy automobile backrest composite sheet, the average fiber footpath of the carbon fiber is 1~3 μ
M, carbon fiber list beam diameter is 0.3~0.7mm.
According to above-mentioned new-energy automobile backrest composite sheet, described matrix resin is thermoplastic resin.
The preparation method of above-mentioned new-energy automobile backrest composite sheet, comprises the following steps：
(1) plastic sheet and fiber reinforced thermolplastic composite material sheet material are entered in baking oven by conveyer belt respectively, shape
Into two superimposed structure up and down, heating, baking oven heating-up temperature is 100~200 DEG C, standby after heating；
(2) preparation of resin sheet：First matrix resin is heated and softened, heating-up temperature is 150~250 DEG C；Then by fibre
Dimension layer is impregnated into the matrix resin after heating, and then 10~20min of dip time dries naturally, standby；
(3) die treatment：New-energy automobile backrest mould is cleared up, releasing agent is then sprayed；
(4) preparation of new-energy automobile backrest：The two superimposed structure and step (2) that step (1) is processed
To resin sheet insert in new-energy automobile backrest mould, compression molding, 1500~1800T/M2 of die pressure, upper mould
30~80 DEG C of temperature, lower 30~80 DEG C of mould temperature, 40~90s of dwell time, the demoulding；
(5) conveyer belt is continued on in steel belt pressing machine, is applied pressure by steel belt pressing machine, is become a table
