2, 0.9～1.5kgf/mm particularly preferably
2
Tensile elasticity rate when strengthening 180 ℃ of plane materiel is less than 0.8kgf/mm
2The time, though the rigidity of formability and dimensional stability are good, the extensibility of the reinforcement plane materiel when being shaped reduces, easy cracking when being shaped is not suitable for.
On the other hand, strengthen the tensile elasticity rate of plane materiel above 2.0kgf/mm
2The time, formability is good, but the change in size of the formed body in the process that the shaping strain relaxes in time and shape avalanche become large, therefore are not suitable for.
(foaming body)
There is no particular limitation for the resin of formation foaming body among the present invention, uses thermoplastic resin material.From cost and carry out deep drawing shaping aspect, preferably use the resin of the TPO of non-crosslinked.Particularly preferably use the resin of high, the inexpensive PP type of heat resistance and rigidity in the polyolefin resin.As polypropylene-based resin, melt flow rate (MFR) (MFR, 230 ℃) preferred 5～30g/10 minute, be more preferably 5～20g/10 minute.
There is no particular limitation for wire harness boundling foaming body among the present invention, can obtain by the wire harness continuous extrusion foaming method that spues from a plurality of mouthfuls of mould nozzles.For example, it is that 0.5～3mm, opening number are the extruder of 50～5000 porous type mouth mould that foaming body can have opening diameter by use, 160～250 ℃ melt extrude under the temperature, the discharge-amount V of each opening of mouthful mould is made as 0.03～0.5kg/h, will close on mouthful resin pressure of mould peristome is released into the method for carrying out extrusion foaming under the atmosphere with 3～20MPa and obtains.
But, high to the tensile elongation of its vertical direction with respect to the tensile elongation of extruding direction to foaming body when foaming body uses wire harness boundling foaming body, for having anisotropic material.
Among the present invention, the expansion ratio of foaming body is preferably 10～40 times, preferred 13～30 times.Expansion ratio is during less than 10 times, and it is good that plane materiel is strengthened the rigidity of foaming body, but diminish light weight, therefore is not suitable for.When expansion ratio surpasses 40 times, though strengthen aspect the light weight of foaming body and the cost well at plane materiel, can't give rigidity, diminish dimensional stability, therefore be not suitable for.
(plane materiel reinforcement foaming body)
Plane materiel reinforcement foaming body among the present invention is made by two surperficial laminated reinforcement plane materiels at foaming body, and its shape can adopt tabular or sheet.
There is no particular limitation for the laminating method of foaming body and reinforcement plane materiel, having on one side makes thermoplastic resin be impregnated in glass fibre non-woven, make thermoplastic resin moderately ooze out into the inner surface of glass fibre non-woven on one side, take this to use the cementability of thermoplastic resin, will strengthen plane materiel and the laminated method of foaming body; Prepare in advance glass fibre non-woven contain the reinforcement plane materiel that is soaked with thermoplastic resin and, the foaming body laminated with it, in subsequent processing, utilize hot-rolling to make both laminated methods; The method of both being fitted with the laminated method of hot air type etc.
As make thermoplastic resin and non-woven fabric compounded in the laminated method of foaming body, have the extruding layer platen press and, injecting type hot melt layer platen press.The extruding layer platen press exists device large, needs larger place, the very high shortcoming of device price, but advantage is the thermoplastic resin that can be coated with easily high mass area ratio with the mass area ratio than homogeneous.Injecting type hot melt layer platen press can be processed with lower cost, but shortcoming is the mass area ratio heterogeneity of thermoplastic resin, or is unsuitable for the coating of the resin of high mass area ratio.
Also have, prepare in advance when strengthening plane materiel and also can suitably process by above-mentioned extruding layer platen press or injecting type hot melt layer platen press.
The method that preprepared reinforcement plane materiel is fitted with hot-rolling is under the state of two surperficial stacked reinforcement plane materiels of foaming body, the method for using the roller through heating to pressurize to fit.
When utilizing hot-rolling to fit, have the easy advantage of processing method, but shortcoming is to strengthen the thickness of plane materiel when thick, the thermoplastic resin melting for can be fully bonding with foaming body needs to consume a large amount of heats.Consequently have following shortcoming: promote hot-rolling heat, increase hot-rolling size, need a plurality of hot-rollings, cause reducing process velocity.
The method that preprepared reinforcement plane materiel is fitted with the hot air type laminating be to foaming body with strengthen simultaneously blowing hot-air of plane materiel, make the softening melting of resin on surface separately after, the limit is with chill roll pressurization cooling, the method that the limit is fitted surface separately.
The hot air type laminating is deposited the in design complicated and shortcoming for making the fully softening melting of material must blow the hot blast of high temperature of device.But advantage is device cheaply and not limited by the place, easily control when wanting to make the heating-up temperature homogenization of goods width with becoming more meticulous, can simultaneously foaming body be fitted with being impregnated in the thermoplastic resin heating and melting of strengthening plane materiel, even therefore in the fast situation of process velocity, also can fit fully processing.
The plane materiel that obtains is as mentioned above strengthened foaming body can also carry out stamping or vacuum forming in subsequent handling.
When stamping, make base material soften melting by preheating, utilize cooling to be compressed and molded into certain given shape, can be in advance at the surperficial stacked adhesive linkage of formed body, pressurization time, be the ornament materials such as the olefin type elastomer of representative (TPO) sheet material at the surface of base material applying felt and ethylene propylene diene rubber (EPDM), EP rubbers (EPR), butyl rubber grafted polyethylene etc.In addition, also can be in advance, in the manufacturing procedure of strengthening plane materiel, make the high resin meltings of transfer printing such as the olefine kind resins such as polypropylene or polyethylene or above-mentioned olefin type elastomer, cast in the glass fibre non-woven surface, make the reinforcement plane materiel, use it to make plane materiel and strengthen foaming body, when compressing, make the concaveconvex shape of mould be transferred to the surface of formed products, give outward appearance.
Also as aforementioned, at the formed products ornament materials of fitting, or the high resin of compound transfer printing in the manufacturing procedure of strengthening plane materiel in advance takes this to carry out the transfer printing of mold shape, can give outward appearance in the time of shaping during vacuum forming.
The content that plane materiel is strengthened the glass fibre of foaming body is preferably 10～20 quality % in the gross mass of plane materiel reinforcement foaming body, be more preferably 12～18 quality %.The content of glass fibre is during less than 10 quality %, diminish the thermal dimensional stability of formed products, for example under the severe cruel situation of built-in material isothermal humidity environment of automobile, use at that time, the size shrink that plane materiel is strengthened foaming body can occur, therefore the unfavorable conditions such as shape avalanche are not suitable for.Particularly, in the situation of the large deep drawing formed products of distortion that becomes second nature, it is large that residual stress becomes, so size shape stability and shape stability are damaged significantly.
On the other hand, if when the content of glass fibre surpasses 20 quality %, can improve the dimensional stability that plane materiel is strengthened foaming body, but diminish light weight, or cracking when strengthening the too high and moulding of the tensile elasticity rate of plane materiel, therefore be not suitable for.
Among the present invention, various physics values are following tries to achieve.
