Abstract
The invention relates to a method for preparing a composite type interior trimming panel part of an automobile. The composite type interior trimming panel part of the automobile is composed of a base plate, a facing layer and a plastic insert, wherein a polymer matrix fibrilia composite material is taken as the base plate, the facing layer is arranged on the outer side surface of the base plate, and the plastic insert is arranged on the inner side surface of the base plate. The preparation method comprises the following steps: the polymer matrix fibrilia composite mat material is taken as the raw material and is heated under the temperature of 170-250 DEG C for 50-200s to be a plasticization state, so as to obtain the base plate through compression molding; two components of polyurethane glue are sprayed on the outer surface of the base plate; the glue body on the surface can be activated through heating, and the facing layer is composited on the base plate through mould pressing; and the plastic insert is stuck on the inner side surface of the base plate through hot-melting glue. According to the method, the prepared composite type interior trimming panel part of the automobile has the characteristics that the part is light and environmentally-friendly, the sound-insulation property and the heat-insulation property are excellent, the part is easily molded, and the investment cost in equipment is low.
Description
Technical field
The present invention relates to a kind of method for preparing compound vehicle trim panel parts.
Background technology
Along with the continuous enhancing of the consciousness such as people's protection of the environment, energy savings, cost performance, more and more higher to the requirement of automobile and automotive trim, market competition is more and more fierce.Client has higher requirement to 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, cost of product is minimized.The lightweight of interior material, environmental protection, low noise, high strength have become a kind of trend, change processing technology and become the most direct the most effective method under the equal crudy of equivalent material.At present, mainly make the automotive trim plate with injection mo(u)lding, its production process is with skeleton substrate and inboard inserts integrated injection molding, pastes skin material again.This product injection mo(u)lding frock is complicated, cost of manufacture is higher, and product weight is large, sound isolating and heat insulating performance is relatively poor.
Summary of the invention
The object of the invention is to provides a kind of novel method for preparing compound vehicle trim panel parts for overcoming the shortcomings such as the cost that present production automotive upholstery exists is high, weight is large, sound isolating and heat insulating performance is relatively poor.
Compound vehicle trim panel parts of the present invention, be by with Polymers flaxen fiber composite material as substrate, consist of at the topcoat on the substrate lateral surface and the plastic insert on the substrate medial surface, its preparation method may further comprise the steps:
A, take Polymers flaxen fiber composite felt material as raw MAT'L, under 170 ~ 250 ℃ of temperature, heat 50 ~ 200 seconds to plastifying state, make described substrate by compression molding;
B, with the two component Polyurethane glues of the outside face of aforesaid substrate spraying;
C, with the above-mentioned base plate heating that makes to surperficial colloid active state, described topcoat mold pressing is compounded on the substrate;
D, described plastic insert is combined in by melt viscosity on the medial surface of substrate, namely obtains compound vehicle trim panel parts product.
Described Polymers flaxen fiber composite felt material is by natural ramie fiber 45 ~ 50%, polypropylene fibre 50 ~ 55%(mass ratio) or natural ramie fiber 45 ~ 50%, polypropylene fiber 20 ~ 35%, polyster fibre 10 ~ 20%(mass ratio) make.
Described topcoat is nonwoven fabrics, fabric, PVC material or TPO material.
Adopt the compound vehicle trim panel parts of the inventive method preparation, have that light weight, environmental protection, sound isolating and heat insulating performance are superior, easy-formation, the characteristics that the equipment investment cost is low.
Description of drawings
Fig. 1 is the compound vehicle hat rack trim panel block construction External view that adopts the inventive method preparation;
Fig. 2 is the cutaway view of A-A shown in Fig. 1;
The specific embodiment

This compound vehicle hat rack trim panel parts are to make by following process:
A, take Polymers flaxen fiber composite felt material as raw MAT'L, under 170 ~ 250 ℃ of temperature, heat 50 ~ 200 seconds to plastifying state, make described substrate (2) by compression molding;
B, with the two component Polyurethane glues of the outside face of aforesaid substrate (2) spraying;
C, the above-mentioned substrate that makes (2) is heated to surperficial colloid active state, described topcoat (1) mold pressing is compounded on the substrate (2);
D, described plastic insert (3) is combined in by melt viscosity on the medial surface of substrate (2), namely obtains compound vehicle hat rack trim panel parts product.
Described Polymers flaxen fiber composite felt material is by natural ramie fiber 45 ~ 50%, polypropylene fibre 50 ~ 55%(mass ratio) or natural ramie fiber 45 ~ 50%, polypropylene fiber 20 ~ 35%, polyster fibre 10 ~ 20%(mass ratio) make.
Described topcoat (1) is nonwoven fabrics, fabric, PVC material or TPO material.
Employing the inventive method can be widely used in preparing other the many trim panel parts on the automobile, such as door inner decoration board, A, B, C, D post trim panel etc.
Claims (3)
