In the time of T mould extruder, extrusion molding for example, by be used to form (i) the first non-foamed resin layer, (ii) containing the resin bed of blowing agent and (iii) each resin combination of three layers of the second non-foamed resin layer add respectively in independent barrel, use T mould to extrude three kinds of resins simultaneously.As this T mould, can enumerate branch manifold formula and feed block formula.
In addition, as the multilayer while extrusion molding of cylinder pattern extruder, first, same with T mould extruder, after extruding, obtain laminated body cylindraceous, then in laminated body, carve the otch parallel with extruding direction and open film, just can obtain flat membranaceous laminated body.
The above-mentioned laminated body that above-mentioned coextrusion is shaped, the mode contacting with base material with the first non-foamed resin layer, is stacked on base material directly or indirectly, can manufacture thus foaming wallpaper laminated body of the present utility model.Particularly, both can the resin combination of extruding from extruder (comprise formation the first non-foamed resin layer, contain the resin bed of blowing agent, the composition of the second non-foamed resin layer) be directly stacked on base material, also can be by the cooling rear masking of the resin combination of extruding from extruder, resulting laminated body is overlapped and on base material, carries out heat lamination.No matter be in any situation, the first non-foamed resin layer is all stacked on base material under the state of melting, therefore good with the tack of base material.
In addition, for foaming wallpaper laminated sheet of the present utility model, also can, in the front and back that are stacked on base material, to above-mentioned laminated body, carry out electron beam irradiation as required.Electron beam irradiation is by the resinous principle containing the resin bed of blowing agent is cross-linked to adjust the melting tension force of resin, thereby can improve foam characteristics.In addition, electron beam irradiation can improve the surface strength of above-mentioned laminated body.With regard to the illuminate condition of electron beam, accelerating potential is 150～250kV left and right preferably, more preferably 175～200kV left and right.Exposure is 10～100kGy left and right preferably, more preferably 10～50kGy left and right.As electron beam source, can use known electron beam illuminating device.In addition, this electron beam irradiation also can carry out after forming floral designs layer, protective layer.
foaming wallpaper
Foaming wallpaper of the present utility model can be by obtaining the foaming of the resin bed containing blowing agent of above-mentioned laminated sheet.For example; as shown in Figure 2; utilize 1 coextrusion on base material of multilayer extrusion machine be shaped the first non-foamed resin layer 2, containing resin bed 3 and the second non-foamed resin layer 4 of blowing agent; on the second non-foamed resin layer 4, form after floral designs layer 5; on floral designs layer 5, form protective layer 6 producing foamed wallpaper laminated sheets, then, by heat treatment; to become foamed resin layer 10 containing the resin bed 3 of blowing agent, the foaming wallpaper shown in thus can shop drawings 3.Heating condition during for foaming, so long as form the condition of foamed resin layer by the decomposition of thermal decomposition type blowing agent, does not just limit.Heating-up temperature is 210～240 ℃ of left and right preferably, and the heat time is preferably about 20～80 seconds.In addition, according to same step, can be used by the foaming wallpaper of Fig. 6 and Fig. 9 the foaming wallpaper of laminated sheet shop drawings 7 and Figure 10.In addition, Fig. 3,7 and 10 foaming wallpaper also can, at the foaming wallpaper that makes Fig. 1 after resin bed 3 foaming containing blowing agent with laminated sheet, form floral designs layer 5 grade and manufacture on the second non-foamed resin layer 4.
In the utility model, heating during foaming by containing the resin bed of blowing agent, resin melting, (foaming welding) melted at the interface of the interface of the first non-foamed resin layer and foamed resin layer and foamed resin layer and the second non-foamed resin layer.That is,, in foaming wallpaper of the present utility model, except because above-mentioned coextrusion is shaped the tack obtaining, can also obtain the tack that the fusing because of above-mentioned two interfaces obtains.Therefore,, in foaming wallpaper of the present utility model, the tack of the tack of base material and the first non-foamed resin layer, the first non-foamed resin layer and foamed resin layer and the tack of foamed resin layer and the second non-foamed resin layer are good.
Foaming wallpaper of the present utility model as shown in Figure 3, also can apply the embossed pattern 11 being obtained by embossing processing above most surface layer.Embossing processing can utilize the known methods such as embossing plate to implement.For example, in the situation that most surface layer is above-mentioned protective layer, by after protective layer thermoplastic, press embossing plate, thus, can give the embossed pattern of expection.As embossed pattern, such as having, grain board conduit trough, stone plate surface are concavo-convex, cloth superficial makings, pear-skin texture pattern sample, sand streak, hairline, ten thousand ducts (ten thousand Line bar Ditch) etc.
Foaming wallpaper of the present utility model, as shown in Fig. 4,8 and 11, also can have from foaming wallpaper surface and connect a plurality of holes (through hole) 9 to base material 1.Foaming wallpaper there is through hole, thus, can guarantee with by the gas permeability of wall covering surface.Therefore, the bonding agent that can promote to construct dry, also can reduce and mildew etc.In addition, when foaming wallpaper is bonded on metope, be difficult for producing bubble between metope and foaming wallpaper, can access the attractive in appearance effect that completes.
As the perforation processing that forms through hole in foaming in wallpaper, can enumerate: the method puncturing with pin etc., perforation processing, the processing of laser decorated fire etc.As the method puncturing with pin etc., for example, can enumerate the crimping with porcupine roller.As perforation processing, for example, can enumerate the method for utilizing perforating press.As the processing of laser decorated fire, for example, can enumerate the method for utilizing laser beam perforation machine.
As the pattern of implementing perforation processing, for foaming wallpaper, can be according to required selection clathrate, zigzag, irregularly shaped etc.
In the situation that implementing cancellate perforation and being processed to form through hole, preferably 1～20mm spacing, more preferably 2～10mm spacing.Above-mentioned " spacing " is the interval of adjacent Kong Yukong.
In addition, as the size of through hole, from inconspicuous reason, consider, preferably the through hole in 40～250 μ m apertures, the more preferably through hole of 50～150 μ m.
Invention effect
Foaming wallpaper laminated sheet of the present utility model, particularly utilize the coextrusion of multilayer extrusion machine to be shaped above-mentioned the first non-foamed resin layer that comprises vinylite, the above-mentioned resin bed containing blowing agent and above-mentioned the second non-foamed resin layer, therefore, cementability between each layer is good, and production is good.In addition, the kind of the blowing agent that can use unlike emulsion method for making is restricted, therefore, easily according to desired foaminess, adjusts blowing agent.In addition, the tack of the tack of first of foaming wallpaper of the present utility model the non-foamed resin layer and foamed resin layer and foamed resin layer and the second non-foamed resin layer is good.In addition, foaminess is good, therefore, is applicable to embossing processing.
