The specific embodiment
The interior dress plate of an embodiment of the present invention and the manufacture method of core and core thereof are described.
The core material structure of expression present embodiment in Fig. 1.As shown in Figure 1, sheet material 2 two faces (surface and the back side) of being adhesively fixed on honeycomb structure 1 are respectively gone up and are constituted core 7.Bonding agent as on being used for being bonded in above two of honeycomb structure 1 to sheet material 2 can use non-aqueous bonding agent.The moisture owing to can not shed during non-aqueous adhesive hardens is not so after sheet material 2 was fixed on two faces of honeycomb structure 1, moisture can be closed in the inside of honeycomb structure 1.
In the present embodiment, the structure and material of sheet material 2 is not particularly limited.For example pass through non-aqueous adhesive applicating on whole of sheet material 2, can be non-aqueous bond layer as damp course, perhaps not non-aqueous bond layer as damp course, and use material as sheet material 2 with moisture resistance, also can realize the moisture resistance of core.Like this, irrelevant with the structure and material of sheet material 2, the core 7 that can obtain having moisture resistance.As a result, even between the inside (inside of honeycomb structure) of interior dress plate and outside, produce temperature difference, also can prevent from dewfall to take place in the inside of the honeycomb structure 1 of core 7.In order further to improve the moisture resistance of core, preferably non-aqueous bond layer as damp course, and adopt and have the material of moisture resistance as sheet material 2.
Secondly, an example of the structure of expression sheet material 2 in Fig. 2.The sheet material 2 of the structure example shown in Fig. 2 lamination between two paper substrate parts 3 has the intermediate member 4 of synthetic resin sheet materials such as polyethylene sheets or metal forming etc.And the best non-retractility of sheet material 2.By the sheet material 2 that uses non-retractility, when the direction that makes core 7 bendings applies power, can suppress the bending of core 7 owing to the non-retractility of sheet material 2, and the rigidity of core 7 is improved.
As non-aqueous bonding agent, can use hot-melt adhesive, biliquid response type bonding agent and solvent based bonding agent etc.Particularly as these bonding agents, the bonding agent of moisture-curable type preferably.
The hot-melt adhesive of moisture-curable type is the bonding agent of sclerosis with airborne moisture (moisture) reaction, as the one example, to PUR (polyurethane reactant: Poly Urethane Reactive) set forth.PUR is that the resin with polyurethane kind is the bonding agent of primary raw material, after the heating for dissolving with airborne moisture (moisture) reaction and harden.During with bonding honeycomb structure 1 of moisture-curable type hot-melt adhesive and sheet material 2, owing to the reaction of moisture of moisture-curable type hot-melt adhesive and honeycomb structure 1 inner space is hardened, the amount of moisture that remains in honeycomb structure 1 inner space is descended.Dewfall takes place in the inside that therefore can further be suppressed at core 7.When particularly using PUR, and reaction of moisture, after the PUR sclerosis, even heating is not melted yet again.Therefore, even under the situation of core 7 in being exposed to a little environment of slight heat, sheet material 2 can not peel off from honeycomb structure 1 yet, can keep the rigidity of core 7.If sheet material 2 peels off from honeycomb structure 1, then honeycomb structure 1 (fuse) becomes free state, and to the resistance forfeiture of bending, the rigidity of core 7 will descend.
Biliquid response type bonding agent is by curing agent being mixed with host, utilize the bonding agent of chemical reaction sclerosis, for example can using polyurethanes bonding agent etc.The solvent based bonding agent is the bonding agent that gasifies, sheds and harden by the solvent in the bonding agent.These all are non-aqueous adhesives, can be used in core of the present invention.
Secondly, the manufacture method to above-mentioned core 7 describes.Fig. 3 represents to make continuously an example of the method for core 7.Sheet material 2 is rolled into tubular and can supplies with continuously.Afterwards, the origination side from the back side of sheet material 2 applies non-aqueous bonding agent 5 in turn.The part that is coated with non-aqueous bonding agent 5 in the sheet material 2 overleaf is placed on the surface of the honeycomb structure 1 that ships continuously, with backer roll 10 pressurizations.Thus, sheet material 2 is close on the surface of honeycomb structure 1.Afterwards, cut off sheet material 2 with the size that does not have the corresponding honeycomb structure 1 of illustrated cutter.Make core 7 by bonding agent 5 sclerosis.
When using hot-melt adhesive as non-aqueous bonding agent 5, as shown in Figure 3, both can be about to bonding before the lysed hot-melt adhesive of coating, also can use the thing (hot-melt adhesive of sclerosis) that is coated with hot-melt adhesive in advance overleaf.Under the latter event, heater is set,, just can be adhesively fixed on sheet material 2 on the honeycomb structure 1 by heating simultaneously with pressurization in the inside of backer roll 10.
With the core 7 that such manufacture method can be tackled various sizes, long core 7 is also made easily.And then, can carry out the continuous production of core 7, and stay-in-grade core 7 can be provided.Also can be the size cut-out in accordance with regulations of the core 7 of the length that produces.Cutting off size can change arbitrarily.
Interior dress plate to present embodiment describes below.The structure and the manufacturing process of the interior dress plate of present embodiment are shown in Fig. 4.At first, preparing the framework corresponding with the size of the interior dress plate of making 6 reaches corresponding with the size of framework 6 inboards and core 7 that produce.At this moment, core 7 can be the monomer that has with the roughly the same size of the size of framework 6 inboards.Perhaps as shown in Figure 4, also can make the roughly the same size of size to a plurality of core 7 combinations with framework 6 inboards.The combination of core 7 is freely, both can be along the length direction of framework 6 a plurality of cores 7 arranged side by side, and also can broad ways a plurality of cores 7 arranged side by side.Can also can use suitable core 7 corresponding to the structure choice of interior dress plate respectively along length direction and width a plurality of cores 7 arranged side by side of framework 6.
And when core 7 is filled in framework 6 inboard, just wooden decorative plate 8 is attached on its two sides (surface and the back side) and fixes with bonding agent etc.Also can go up at a face (back side) of framework in advance and paste fixedly wooden decorative plate 8.
The interior dress plate that produces like this can be used for the side plate of door, spaced walls, inwall, casing etc.Should interiorly adorn in the plate, owing to use the core 7 that by non-aqueous bonding agent sheet material 2 is bonded in the surface and the back side of honeycomb structure 1 as mentioned above, even so do not give moisture resistance, also can further suppress crooked generation, make stay in grade to wooden decorative plate 8.
Certainly, the present invention also can't help above-mentioned embodiment and limits, much less the structure of the shape of honeycomb structure 1, material, structure and sheet material 2, material, also have the details such as structure of wooden decorative plate 8 that variety of way can be arranged.
