Description

[Detailed Description of the Invention] The present invention provides an interior material suitable for flooring and wall materials.
In recent years, there has been a strong demand for interior materials with a transparent wear-resistant layer on the surface to have a matte surface. on the other hand,
When used as a flooring material in the home, there is a need to improve the feeling of walking barefoot or with slippers. In other words, when you walk barefoot on polyvinyl chloride (PVC) soft sheet flooring such as conventional cushion floors, the surface of the flooring sticks to your feet and feels sticky, and even when you walk in slippers, the flooring sticks to your feet. The flooring lifted up every time I walked, making it difficult and uncomfortable to walk on.

As a matting method, a method in which a matting agent is mixed and dispersed in a transparent resin may produce a matting effect, but it cannot eliminate the discomfort caused by the flooring material clinging to bare feet.

In addition, as a matting method, a method of applying grain to a transparent film with a grain roll and laminating it on the surface, or a method of finally adding grain to the surface layer, but in the former, the grain disappears when foaming after lamination, and in the latter In this case, even if the foam is embossed, the embossment is weak, and these methods do not solve the above-mentioned drawbacks.

The present invention provides an interior material that is matte and provides a good walking feel, and includes a pattern layer on a base material, a transparent resin layer laminated on the pattern layer, and an average grain size on the surface of the transparent resin layer. Diameter 10~70μ and 0.1~
The gist is a matte interior material characterized by a mixture of polyvinyl chloride powder consisting of 5μ and containing a plasticizer being fixed in a semi-molten state, and a pattern layer being transparent.

This will be explained below based on the drawings.

FIG. 1 is a sectional view of the interior material of the present invention.

1 is asbestos and is a backing material of paper or non-asbestos sheet, glass mat or other woven or non-woven fabric. 2 is a foam such as PVC with a thickness of 1 to 5 mm, and the base material 3 is formed by the backing material and the foam. Note that the base material does not need to be a foam as long as it is flexible, and a non-foaming synthetic resin or the like can be used. 4 is a pattern layer. The foam may be chemically embossed using a blowing agent suppressing ink as appropriate in the printed pattern. A transparent PVC base sol is applied onto the printing layer. In order for the PVC powder 6 to be fixed to the transparent resin layer 5 in a semi-molten state, the PVC powder is sprinkled on the surface of the paste sol before the paste sol is solidified.
Next, it is efficient and desirable to heat the paste sol to form the transparent resin layer 5 and at the same time turn the PVC powder 6 into a semi-molten state, followed by cooling.

PVC powder 6 used in this invention is vinyl chloride homopolymer, vinyl chloride and vinyl acetate, (meth)
A copolymer with an acrylic ester or the like can also be used, and the powder is composed of an aggregate of a mixture of PVC powder with an average particle size of 10 to 70μ and 0.1 to 5μ, and is impregnated with a plasticizer. Powders with an average particle size of 10 to 70μ can be obtained by the suspension method, and powders with an average particle size of 0.1 to 5μ can be obtained by the latex spray drying method.The average degree of polymerization is
700-2000, the weight ratio of 10-70μ powder to 0.1-5μ powder is 1/4-4. The above PVC powder mixture is preferably sprinkled on the PVC paste at a rate of 30 to 500 g/m ² . This PVC powder can also be used in the form of a powder coating.

In the present invention, when the base material includes a foam layer formed by chemical foaming, a transparent paste is applied to the foam sheet in a pregel state, and a mixture of PVC powder is sprinkled on the foam sheet.
The foamable sheet is heated to foam, the transparent paste is heated and solidified, and the PVC powder is brought into a semi-molten state and fixed to the surface of the transparent resin layer.

Further, the pattern layer 4 can be seen through the transparent resin layer 5 from the surface, and transparency is not impaired in any way.

Since the present invention has the above configuration, it has the following effects.

1. The transparency of the transparent resin layer does not change and the decorative properties are not impaired.

2. Since the thermoplastic synthetic resin powder is adhered to the surface of the transparent resin layer in a semi-molten state, the powder will not peel off from the flooring material and the effect will be permanent.

3. Since it is matte, light reflects diffusely and is not irritating to the eyes.

4. Even when walking barefoot on the invented flooring material, the sticky feeling on the feet is eliminated and the feet feel smooth, and the soles of the slippers do not cling to the soles of the slippers and lift up, providing a pleasant barefoot feel, making walking comfortable, especially in the summer. It provides a good feel and also provides some slip resistance.

5. In the present invention, even when the base material contains a foam, a good matte effect and a comfortable barefoot feel can be obtained.

6. Powders with different average particle sizes are combined and stuck together in a semi-molten state, and as a result, the surface of the interior material is difficult to stain.

Example A 0.3 mm PVC foamable paste sol was coated on a 0.5 mm asbestos paper and heated to pre-gel, and a pattern layer was provided by thermally transferring a transfer paper printed with an ink partially containing a foam inhibitor. Further, a transparent PVC paste sol was applied onto the pattern layer, a composition having the following formulation was stirred with a ribbon blender, and the obtained powder was sprinkled on the above transparent PVC paste sol.

PVC suspension powder (average particle size 30μ)
50 parts by weight PVC powder (average particle size 1.5 μ) 50 parts by weight D O P 40 Ba-Zn stabilizer 2.0 Next, the obtained sheet material was heated to foam the foamable layer and give chemical embossing. , transparent
While the PVC paste sol was cured, a semi-molten PVC powder mixture was adhered to its surface. The resulting product is sufficiently transparent through the transparent resin layer to allow the pattern layer to be seen through, and since it is matte, it is less irritating to the eyes and does not cling to bare feet when walking, making it smooth and smooth. An excellent flooring material that is comfortable and stain-resistant was obtained.
