Description
Technical field
The present invention relates to a kind of band epidermis plate and manufacture method and applying blow molding method of making through blow molding that uses as dress plate in the motor vehicle.Band epidermis plate is the interior finishing panel for vehicle that the cover plate, refractory slab as motor vehicle luggage casees such as floor panel, luggage boxboard, shelf etc. etc. uses, and has the epidermis thin plate is sticked into one two layers of walls structure of hollow of making through blow molding.The epidermis thin plate is formed by stacked nonwoven on resin sheet, and resin sheet is formed with the space pattern of being made up of thermoplastic resin.
Background technology
The floor panel of motor vehicle, luggage boxboard etc., the cover plate of motor vehicle luggage case etc., for make its surface touch good, have design effect, use always the epidermis thin plate of on the surface of plate, pasting nonwoven etc. material (with reference to the spy open flat 1-34720 communique, the spy opens the 2000-289095 communique).Yet,, outside the existing plate of pasting nonwoven, increase day by day having applied demand space patterns such as textured pattern, that resin sheet is welded the plate that forms for one on the market along with the variation of the using method of motor vehicle luggage case etc.
For example, it is described to open flat 9-39078 communique according to the spy, on the table wall of plain cotton fabric hollow forming product (plate), when blow molding, make the bunting stickup of 3 layers of structure of epidermis thin plate, foaming body, thin fiber board be one, thin fiber board is that order pays weight 50～250g/m
2Nonwoven.It is described to open flat 9-39079 communique according to the spy, on the table wall of plain cotton fabric hollow forming product (plate), when blow molding, the epidermis thin plate of adhering resin thin plate and thin fiber board and its stickup is integral, and resin sheet is tensile elasticity rate 3000～12000kg/cm
2Polypropylene or PET resin.
In addition, the spy opens when recording blow molding in the clear 62-255117 communique all-in-one-piece manufacturing process is pasted in coating (epidermis thin plate) heating back, and the epidermis thin plate forms the relief pattern of roller mould for pasting nonwoven at flexible PVC.In addition, open in the flat 10-235720 communique the spy, record be used for motor vehicle the cargo floor panelling, the cloth (nonwoven) that has fur is pasted be the band epidermis plate of one, this plate has internal-rib.Also have in addition, opening 2001-277342 communique and spy according to the spy, to open the 2004-74660 communique described respectively, form hinge (hinge) portion after the part compression thinning with parison during blow molding with groove, viewpoint from the adhesive strength that improves the epidermis thin plate sandwiches nonwoven between epidermis thin plate and parison.
The band epidermis plate that blow molding is made is the parison of epidermis thin plate and molten condition to be fit together to form when being shaped.Use the situation of the resin sheet of non-gas permeability, have the problem that air retains between the resin sheet be configured in the mould and the parison as the epidermis thin plate.In order to prevent this problem, the general resin sheet that accompanies foaming body or nonwoven etc. that uses.
Yet, in interior finishing panel for vehicle etc., form concavo-convex space patterns such as trickle textured pattern or well-regulated burr shape on the outer surface of expectation epidermis thin plate.But when using the resin sheet with concavo-convex space pattern to carry out blow molding, under the effect of the heat that pressure when blow molding and parison send, concavo-convex space pattern produces broken and distortion.In addition,, particularly extremely stretched, cause aesthetic appearance to be badly damaged at the concavo-convex space pattern of its end portion because resin sheet is stretched.
In addition, as the method that on the outer surface of epidermis thin plate, forms concavo-convex space pattern, can adopt along the chamber of mould makes concavo-convex space pattern carry out methods such as transfer printing, but the resin sheet thickness that accompanies foaming body or nonwoven etc. generally speaking is big, and the transfer printing of the space pattern that carries out according to the chamber of mould becomes insufficient.Especially from the viewpoint of formability, exist not resin sheet is carried out can not forming the space pattern with good appearance under the situation that preheating makes it to soften.
In addition, in interior finishing panel for vehicle, in order to improve the rigidity of hollow two double wall tectosomes, formation welds the rib into one from the outstanding back side with the table wall of back wall, when using as floor box, the floor box that correspondence is classified, in order to make it the part folding, formation will be shown wall and back wall and weld hinge part into the thin shape of one.At this moment, because rib and hinge partly are table wall and back wall to be welded to one form, there are differences with the corresponding molding condition that welds the part and the part of the hollow bulb that is not welded of table wall and back wall, produce depression or transfer printing generation inequality in the space pattern that causes occurring on the resin sheet surface.As a result, space pattern causes part blunt or damage the low problem of aesthetic appearance that produces owing to transfer printing is insufficient.
In addition, the band epidermis plate that blow molding is made, exist on thin plate end and the hinge part and be easy to generate the problem that the epidermis thin plate is peeled off, in order to prevent peeling off and projection etc. of epidermis thin plate, need take with sliding mould is one with the back-welding shape that the end of epidermis thin plate involves in plate, and the recess that forms wide cut from epidermis thin plate one side on the hinge part is to enlarge the countermeasure of bond area etc.
Summary of the invention
Therefore, between the first wall and second wall, form in the interior finishing panel for vehicle of the hollow two double walls structure that the surrounding wall of hollow bulb constitutes, be made as on resin sheet bonding order to pay weight be 80～250g/m sticking on epidermis thin plate on the first wall
