Abstract
The invention provides a preparing method for an automobile interior trim plate, wherein a base plate is made of hemp fiber polymer composites through the single molding process, a surface cladding is arranged on the outer surface, and an integrated interior trim plate with a plastic insert is arranged on the inside. The preparing method comprises the following specific steps that: fabrics are chucked at the lower end of an upper die, the plastic insert is arranged in the lower die, the hemp fiber polymer composites are heated to plasticizing state, the binding face of the plastic insert is heated to a surface molten state, and the heated hemp fiber polymer composites are immediately laid on the lower die so as to be subjected to the compound extrusion forming. The preparing method can be used for overcoming the defects of the prior production of the automobile interior trim that the procedures are complex, the cost is high, and the environment is easy to pollute.
Description
Technical field
The present invention relates to the preparation method of automotive trim plate, especially a kind of being prepared in promptly has the facial ornament layer, inboard has the method for the integrated interior trim plate of plastics inserts again on its substrate.
Background technology
The continuous enhancing of consciousness such as Along with people's protection environment, energy savings, cost performance, to automobile and automotive trim require increasingly high, the market competition more and more fierce.Client has higher requirement for main engine plants and each supporting enterprise to the pursuit of high performance-price ratio, environment-friendly products.Should make product satisfy client's requirement, product cost is minimized.The lightweight of interior material, environmental protectionization, low noiseization, high strength has become a kind of trend, under the equal crudy of equivalent material, changes processing technology and becomes the most directly method.At present; The automotive trim plate made from polymer base linen fiber composite fiber plate like the production process of door-plate, A, B, C, D post plaque, left and right sides gusset plaque, ceiling plaque, trunk ornamental plate etc. is: polymer base linen fiber composite fiber template die is molded, profiled member spray glue, to paste skin material, side cut, inserts brush coating, inserts and molding bonding.Various with this explained hereafter operation, required human and material resources is big, and beat is slow, and cost is high, and spray glue and brush coating process are prone to cause environmental pollution.
Summary of the invention
The objective of the invention is to that the operation that present production automotive upholstery exists is various, cost is high in order to overcome, be prone to cause shortcoming such as environmental pollution, a kind of improved method for preparing the automotive trim plate is provided.
The inventive method is that to make with polymer base linen fiber composite be substrate through once molding formed, has the integrated interior trim plate that facial ornament layer, inboard have the plastics inserts at its outer surface, and specific practice may further comprise the steps:
A. lining is installed in the patrix lower end; The plastics inserts is placed counterdie, and the binding face of itself and substrate protrudes in the drag surface;
B. the binding face that respectively polymer base linen fiber composite felt material is heated to plastifying state, plastics inserts is heated to the melt surface state; Polymer base linen fiber composite felt material shop after will heating immediately overlays on carries out compound extrusion forming on the bed die; The demoulding; Promptly obtaining with polymer base linen fiber composite is substrate, has the integrated interior trim plate that facial ornament layer, inboard have the plastics inserts at its outer surface.
The present invention prepares the method for automotive trim plate; Traditional multiple operation is become single operation production; Once accomplish hot-forming, side cut, inserts technique for sticking; Reduce traditional handicraft processes such as glue spreading of base plate, substrate and epidermis are compound, joint product is cut edge, the annex gluing is bonding, simplified the production technology that polymer base linen fiber composite fiber plate is produced automotive upholstery greatly, improved production efficiency; And strengthened the combined strength bination of skin material and polymer base linen fiber composite fiber plate, improved environmental-protecting performance simultaneously.
The inventive method can be adaptable across preparation automobile multiple inside gadget product, as: like vehicle door interior trim panel, A, B, C, D post plaque, left and right sides gusset plaque, ceiling plaque, trunk ornamental plate etc.
Description of drawings
Fig. 1 is an embodiment of the present invention method compression molding sketch map;
Fig. 2 is the automobile A column trim panel modular construction figure of embodiment 1 said preparation;
Fig. 3 is the cutaway view of A-A shown in Fig. 2.
The specific embodiment
The embodiment that provides below in conjunction with accompanying drawing does further explain to the present invention.
Adopt the inventive method to prepare automobile A column trim panel parts.
As shown in Figure 1, a. will be installed as the lining 2 of facial ornament layer in patrix 1 lower end; Plastics inserts 4 is placed counterdie 5, and the binding face of itself and substrate protrudes in the drag surface;
B. polymer base linen fiber composite felt material 3 is heated on board-like heater, it is 50～200 seconds that temperature of heating plate is controlled at 170～250 ℃, heat time heating time, is heated to plastifying state; With the contactless heating of electric heater, heater temperature is that 280～350 ℃, heat time heating time are 80～100 seconds, is heated to the melt surface state with the binding face of plastics inserts; Polymer base linen fiber composite felt material shop after will heating immediately overlays on carries out compound extrusion forming on the bed die, pressure is 20～30kg/cm
2, the dwell time is 30～50 seconds, promptly obtains like Fig. 2 after the demoulding, shown in 3 is substrate with polymer base linen fiber composite, has the integrated trim panel parts of A post that facial ornament layer, inboard have the plastics inserts at its outer surface.
Described lining 2 adopts nonwoven, fabric, PVC material or TPO material.
