Abstract
The present invention relates to a high rigidity light weight board for the vehicle inner material, such as trunk cover on which laying heavy or chair back, as well as a method for manufacturing the board; especially, relates to a high rigidity light weight board and its production apparatus, wherein taking light weight material with inanition structure of the hollow part such as comb board, ripple piece or foam piece as substrate, and setting light weight plastic pieces on the upper/lower of the substrate, the light weight plastic piece is complex material piece with prescribed thickness.
Description
Technical field
The present invention relates to the light weight board that in requiring the automotive interior material of high rigidity, uses, as the luggage-boot lid or the chair back that has weight to place on it, and the manufacture method of described plate; More particularly, the present invention relates to a kind of light weight board and manufacture method thereof, wherein, by the light material of hollow structure such as honeycomb plate, corrugated plate or foam piece with hollow sectors as substrate layer, have the light plastic sheet of the composite material sheet work of predetermined thickness on the substrate with substrate, to improve rigidity such as fracture strength, hot strength and the impact strength etc. of plate, pile up the top layer and the bottom of non-weaving cloth again in top and bottom, make plate in die for molding then, thereby make the weight saving of finished product, and rigidity improves.
Background technology
As shown in figure 11, in conventional art, heavy material is positioned at the upper strata of plate 100 ', the plate 15 that 8-12mm is thick or be used to support the weight of institute's load by the substrate 10 ' that medium density fibre board (MDF) (MDF) is formed, with bonding agent top layer 40 ' and bottom 50 ' are bonded at the quality that substrate 10 ' is gone up with the raising product surface, this way makes cost rise, and because the heavy weight of plate 100 ' makes the fuel ratio of automobile descend.Especially, when adhering to non-weaving cloth as top layer 40 ' and bottom 50 ' with bonding agent on substrate of being made up of MDF 10 ' or plate 15, along with bonding agent absorbs moisture, adhesion descends, it is heavy that the weight of product becomes, and finally cause product situations such as mouldy, smelly and distortion to occur.For addressing the above problem; the thistle board of use hollow structure such as hollow template, the plastic composite with high rigidity, corrugated plate, foam piece etc. are used as substrate in product; this product is partly scale also; but only use the words of above-mentioned material; when product during as automotive interior material that needs high rigidity such as luggage-boot lid; can not reach the rigidity that needs, production board in use may warpage or fracture.Especially, though people attempt plate is construed as such structure: in this structure, the plastic sheet of specific thicknesses is stacked and is bonded on the skin of substrate, and described substrate adopts the plate of being made up of hollow space and dividing plate, as hollow template, corrugated plate or foam piece etc.; But, when will go up/when the plastic sheet of lower part piles up/joins on the substrate, the hollow space of substrate make described on/plastic plate of lower part is pressed in the described hollow space, this makes the composition surface injustice, and finally can cause the disengaging in use of plastic sheet and substrate.
Summary of the invention
Therefore, the present invention is devoted to provide a kind of light weight board and manufacture method thereof, and product of the present invention and method have fully overcome because the restriction of prior art and one or more problems that shortcoming is caused.
An object of the present invention is to provide a kind of light weight board and manufacture method thereof, wherein, adopt the material of hollow structure such as plastics or resin molding compound product, honeycomb plate, corrugated plate or foam piece etc. as substrate with hollow sectors; The top layer of plastic sheet, polyester non-woven fabric and bottom are stacked on the upside and the downside of substrate; Above each of piling up is layer molded in mould, obtain lightweight production board, simultaneously, and needed sustained rigidity when described plate has as automotive interior parts such as luggage-boot lid, and connected structure is firm and easy moulding; The invention solves aforementioned problems of the prior art, improved performance such as the rigidity and the water proofing property etc. of product, and provide a kind of light, mould and light weight board that connected structure is firm easily.
First purpose of the present invention is to provide a kind of manufacture method that is used as the plate of automotive interior parts.
For achieving the above object, the present invention has taked following technical scheme:
