Abstract

(57) 【Abstract】 PROBLEM TO BE SOLVED: An interior material made of a resin containing halogen such as PVC generates a toxic gas when incinerated, and as a countermeasure, even if the interior material is simply made of a non-halogen resin, Since it contained a plasticizer, it became a cause of indoor environment pollution, and further warpage occurred and dimensional stability was poor. A halogen-free resin transparent surface layer, a printing layer, and a glass fiber woven or non-woven fabric layer are formed directly under the printing layer, and a halogen-free resin foam layer is formed under the glass fiber layer. An interior material characterized in that the surface layer and the foam layer do not contain a plasticizer.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

 The present invention relates to an interior material such as a floor material and a wall material which has a cushioning property and does not generate a toxic gas when incinerated.

[0002]

[Prior art]

 Conventionally, flooring materials and wall materials obtained from halogen-containing resins such as PVC have been known.

[0003]

[Problems to be solved by the device]

 Interior materials made of a resin containing halogen such as PVC generate toxic gases such as chlorine gas and dioxins when incinerated, and countermeasures have been required. Therefore, in a structure in which a non-halogen resin was used instead of PVC, warpage occurred and dimensional stability was poor. In addition, the plasticizer is present in the interior material and evaporates from the surface, polluting the indoor environment.

[0004]

[Means for Solving the Problems]

 According to the present invention, a resin transparent surface layer containing no halogen, a printing layer, and a glass fiber woven or non-woven fabric layer are formed directly under the printing layer, and a resin foam layer containing no halogen is formed under the glass fiber layer. The gist is an interior material characterized in that the surface layer and the foam layer do not contain a plasticizer.

A description will be given below with reference to the drawings. Reference numeral 1 denotes a surface layer, which is a transparent resin layer, and is preferably a thin film of polyethylene (PE), polypropylene (PP), polyethylene terephthalate (PET), polyurethane (PU) having a thickness of 0.05 to 0.5 mm. The embossing 2 may be appropriately provided on the surface of the layer. The printing layer 3 is formed immediately below the transparent film 1. The printing layer is preferably halogen-free, for example, acrylic resin binder ink. No. 4 is a glass fiber woven or non-woven fabric, and the basis weight is 10 to 100 g / m ² .

Reference numeral 5 denotes a resin foam which does not contain halogen, and PP, PE and ethylene-vinyl acetate copolymer (EVA) foams are preferable, and polyolefin cross-linked foams are particularly preferable. The foam thickness is preferably 1.0 to 5.0 mm, and the expansion ratio is preferably 2 to 15 times. The interior material 7 of the present application is obtained by laminating a woven cloth or a non-woven cloth 6 obtained from a polyurethane resin or a synthetic fiber such as PP, PE, PET, rayon, nylon or vinylon on the back surface of the non-halogen foam. can get.

[0007]

[Form of actual state of invention]

 Since the interior material of the present invention is composed of a resin that does not contain halogen, it does not generate toxic gases such as chlorine gas and dioxin when incinerated, and further, a glass fiber woven fabric or a non-woven fabric is provided immediately below the printing layer, and By laminating a woven or non-woven fabric such as synthetic fiber on the lowermost layer of the interior material, there was no occurrence of warpage or deterioration of dimensional stability like existing non-halogen interior materials. Furthermore, since no plasticizer is contained in the surface layer and the foamed layer, it is resistant to various types of pollution and does not pollute the indoor environment with plasticizer vapor.

【Example】

 Examples and comparative examples are shown below.

First Embodiment A manufacturing process diagram of the present invention of FIG. 2 will be described. A 0.1 mm-thick PP back print film 8 having a print layer formed on the back surface thereof and a glass fiber nonwoven fabric 9 of 50 g / m ² were laminated on the surface of a large heating roll (gelling roll) 10. The obtained laminated body is heated by the heater 11, the hot melt adhesive is applied by the hot melt adhesive application device 12, and the laminated body 13 and the laminated roll 14 of the polyester non-woven fabric having a thickness of 2 mm and the PE electronic crosslinked foam are applied. Then, the PE crosslinked foam was laminated on the inside to obtain an interior material 15.

[0009]

Example 2 The same interior material as in Example 1 was obtained except that EVA foam was used instead of the PE electron-crosslinked foam of Example 1 as the foam.

[0010]

[Comparative Example 1] A PVC paste foam layer was formed on a 50 g / m ² glass fiber non-woven fabric, pregelled, and then a printed layer was formed by transfer, and a PVC transparent paste having the same thickness as in Example 1 was applied. And foamed by heating. An interior material having a PVC foam layer of 2 mm was obtained. The performances of the obtained Examples 1 and 2 and Comparative Example 1 are shown in "Table 1".

[0011]

[Table 1] Example 1 Example 2 Comparative example 1 No toxic gas during incineration No generation No generation Surface contamination rubber ○ ○ × Copy transfer ○ ○ × Alcohol ○ ○ △ Soybean oil ○ ○ △ Lubricating oil ○ ○ △ Stickiness ○ ○ × Water absorption whitening ○ ○ × Environmental pollution ○ ○ × Warpage prevention ○ ○ ○ ○ Good △ Not good × Bad

The obtained interior materials of Examples 1 and 2 did not generate toxic gases such as hydrogen chloride and dioxin at the time of incineration, were not contaminated by various pollution sources, and were neither sticky nor whitened by water absorption. On the other hand, since the comparative example uses PVC resin, it emits toxic gases such as hydrogen chloride and dioxin when incinerated, and since it contains a plasticizer, it is vulnerable to contamination and causes stickiness and water whitening by absorption. It was a trigger.

[0013]

[Effect of device]

 1. According to the present invention, an interior material which has a clear printed pattern and cushioning property and which does not generate toxic gas when incinerated is obtained. 2. Since the plasticizer did not migrate, the vapor did not pollute the indoor environment, resulting in great environmental safety. 3. There was no rubber pollution, and there was no possibility that the surface of the newspaper would look like a picture and would be contaminated. 4. The gloss did not change without being contaminated with alcohol, soybean oil or lubricating oil. 5. The plasticizer did not migrate and the surface of the interior material was not sticky. 6. Even if the rag was left alone, there was no whitening by water absorption. 7. Despite being made of non-halogen resin foam resin, glass fiber woven cloth or non-woven cloth is interposed, so that warpage does not occur and dimensional stability is improved.
