Height, automotive trim product lightweight, environmental protection, attractive in appearance has become development trend.Flaxen fiber is natural reproducible fiber, and resource is rich
Rich, cheap, it is combined with phenolic resin as raw material by the use of flaxen fiber and be prepared into automobile inner door scaleboard, gusset plate, ceiling etc.
Inside gadget, product weight is light, and intensity is good, indeformable, and attractive in appearance, has the good feature of environmental protection and economy.
This kind of product is generally glass fibre foaming part, glass fibre and polypropylene mixing molding etc., its feature at present
It is that dimensional thickness is big, glass cannot be degraded, polypropylene based material deformation is greatly it is difficult to adapt to current automobile industry environmental protection, lightweight
Requirement.
Flaxen fiber substitutes traditional glass fibre as organic material, not only alleviates weight, solves glass fibre again
The environmental problem that cannot degrade.Application in automotive trim for the flaxen fiber reinforcing material at present is concentrated mainly on polypropylene hybrid guided mode
Bear down on one the products such as paulin, the composite hemp felt described by patent CN200610039121.2, Corchorus olitorius L. as described in CN200910116808.5
Fiber and polypropylene fiber pierce the numb felt of eedle thorn, polymer matrix flaxen fiber enhancing composite described in CN201210588373.6
Deng, be thermoplasticity flaxen fiber composite need heated rear compression molding again.This kind of product density is still larger, and product
Thickness is big, yielding, and production cost is high.
Content of the invention
For deficiency present in existing automotive trim product technology, it is an object of the present invention to provide a kind of flaxen fiber compound die
The manufacture method of pressure automotive upholstery is so as to the flaxen fiber composite coining automotive upholstery product that obtains has lightweight, environmental protection, easily
In the strong advantage of molding, combination property.
In order to solve the above problems, present invention employs following technical scheme：A kind of flaxen fiber composite coining automotive trim
The manufacture method of part, comprises the steps：
1）After flaxen fiber combing, carry out lapping and form 15-25mm thickness continuously numb felt；When carrying out lapping, can adopt parallel
Lapping or cross-lapped method carry out lapping；
2）Numb felt is impregnated in the phenolic resin adhesive having configured；In described phenolic resin adhesive, each constituent content is：
The urea modified phenolic resin of 15-35wt%, the water of the mimosa extract of 5-10wt%, 5-10wt% sodium hydroxide and 55-65wt%；
3）Numb felt after dipping is taken out, dries to moisture content 8-10%, form band compound blank material felt, drying temperature is 50-60 DEG C；
During the numb felt of dipping, the spread of phenolic resin adhesive is 10-25wt%；
4）It is laid on after band compound blank material felt cutting in mould, at 150-200 DEG C, suppressed with the pressure of 3-5MPa,
Dwell time 120-180s, the thickness of workpiece after compacting is 3-4mm；
5）Take out workpiece after die sinking, through repair cut unnecessary rim charge, automotive trim product is made in perforate, application.
Above-mentioned flaxen fiber can mix for one or more of natural Corchorus olitorius L., ambary, Caulis et Folium Lini.
Present invention also offers a kind of a kind of flaxen fiber composite coining automotive upholstery product being obtained according to the method described above.
Compared to the prior art, its remarkable advantage is the present invention：
（1）Using natural ramie fiber as material, flaxen fiber is renewable, degradable, environmental protection；
（2）Carry out gluing using with phenolic resin adhesive, deform little after formed product, in-car organic volatile VOCs is low；Urine
Plain phenol-formaldehyde resin modified is prior art, after its polyreaction, forms carbamide-P-F copolymer resinses, have intensity big,
The good advantage of elasticity, and be easily obtained, low cost；
（3）Mechanical property and weight can be taken into account：The present invention can meet product mechanical property according to different types of gadget product thickness
Can require, reduce product weight；During compacting, numb felt is in layer structure, and phenolic resin adhesive mutually merges, the layer of product and layer
Between be tightly combined, intensity is big, and overall tearing strength in all directions is all very big；
（4）The present invention can be used for manufacturing the interior products such as automobile inner door scaleboard, gusset plate, inner decorative ceiling, after numb felt impregnation directly
Compression molding, molding time is short, low cost.
