Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wood grain wall covering material for building interiors.

[0002]

2. Description of the Related Art Conventionally, a wood grain wall covering material, in which a polyvinyl chloride foam layer, a wood grain pattern, a wood grain conduit ink portion, and a transparent protective layer are sequentially provided on a flame-retardant paper, has been used. There is also utilized a technique of adding a foaming inhibitor to the above to suppress foaming of the portion.

However, in the above-mentioned conventional wood grain wall covering material, since the wood grain pattern and the wood grain conduit ink portion are provided on the same surface, the three-dimensional effect of the wood grain pattern is lacking and the design is not good. However, for example, even if a recess for suppressing foaming is provided by using an ink for printing a wood grain conduit portion with an expansion inhibitor added, it is not possible to form a sharp recess close to the conduit.

[0004]

DISCLOSURE OF THE INVENTION An object of the present invention is to provide a wood grain wall covering material which is improved in designability of the conventional wood grain wall covering material.

[0005]

[Means for Solving the Problems] A wood grain having an improved design effect by sequentially providing a polyvinyl chloride foam layer, a wood grain pattern, a transparent protective layer, and a wood grain conduit ink portion in synchronization with the wood grain pattern on one surface of a flame-retardant paper. It is a handle wall material.

A polyvinyl chloride foam layer on one side of the flame-retardant paper,
A woodgrain pattern, part of which is printed with an ink containing a foam suppressor,
This is a wood grain wall covering material in which a design effect is enhanced by sequentially providing a transparent protective layer and a wood grain conduit ink portion in synchronization with the wood grain pattern.

[0007]

With the transparent protective layer, a wood grain pattern is provided on one side of the transparent protective layer and a wood grain conduit ink portion is provided on the other side of the transparent protective layer in synchronization with the wood grain pattern. With such an arrangement, it is possible to reproduce a three-dimensional deep grain design.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. FIG. 1 is a laminated sectional view of a wood grain wall covering material of Example 1, and FIG. 2 is a laminated sectional view of a wood grain wall covering material of Example 2, where 1 is flame retardant paper and 2 is polyvinyl chloride foam. Layer, 3 is wood grain pattern, 3a
Is a pattern containing a foaming inhibitor, 4 is a transparent protective layer, and 5 is a wood grain conduit ink portion.

The flame-retardant paper 1 has a basis weight of 70 to 80 g / m ² and is impregnated with a water-soluble flame retardant such as guanazine sulfamate and guanazine phosphate.

The polyvinyl chloride foam layer 2 is made of polyvinyl chloride paste resin containing a vinyl chloride sol containing a foaming agent, a coloring agent such as titanium oxide, and an extender such as calcium carbonate.
It is applied to a thickness of 50 to 200 μm and heat-foamed.

The wood grain pattern 3 is printed with a commonly used ink, for example, an ink made of vinyl chloride resin.
When it is desired to form a part of the pattern in a concave shape, the pattern 3a may be formed by adding a foaming inhibitor such as trimellitic acid to the pattern of the corresponding portion. In that case, it is effective to add a foaming inhibitor to a predetermined ink forming the grain pattern to partially form a shallow recess.

As the resin used for the transparent protective layer 4,
An acrylic-urethane type two-component room temperature curing type resin is most suitable as long as it has good leveling property and excellent physical strength, and the thickness of the coating film is suitably 5 to 15 μm. The surface gloss of the transparent protective layer 4 can be arbitrarily set by adding an inorganic powder to the transparent protective layer.

The wood grain conduit ink portion 5 is preferably formed of a matte ink using an acrylic-vinyl chloride type two-liquid room temperature curing type resin and containing 30 to 50% of inorganic fine powder such as silica. .

Polyvinyl chloride foam layer 2 according to the present invention
The method for forming the wood grain pattern 3, the pattern 3a containing the foam suppressing agent, the transparent protective layer 4, and the wood grain conduit ink part 5 is an in-line by the gravure printing method, and the wood grain pattern 3 and the pattern 3a containing the foam suppressing agent It is preferable to perform printing in synchronization with the conduit ink section 5.

Example 1 70 g of flame-retardant paper (WK-ADS, Kojin) was coated with a vinyl sol having the following composition to a thickness of 150 μm, and 190
Heat at 0 ° C for 1 minute to semi-gelate. After forming a wood grain pattern, a transparent protective layer, and a wood grain conduit ink part consisting of the following wood grain conduit ink on the surface of the polyvinyl chloride sol by in-line printing by a gravure printing method, the vinyl chloride sol layer is heated at 220 ° C. for about 1 minute. The foaming was completed to produce a wood grain wall covering material. Composition of PVC sol Unit is by weight PVC paste resin (Kaneka, PSL-280) 100 Plasticizer (DOP) 60 Titanium oxide 15 Calcium carbonate 50 Foaming agent (Otsuka Chemical, AZ-L30) 3 Stabilizer (Kyodo Chemical, KF-) 838) 1 Composition of wood grain ink (Showa ink, G & M type) Resin (acrylic-vinyl chloride) 36 Curing agent (isocyanate) 10 Silica 18 Carbon black 8 Wax 0.2 Solvent (ethyl acetate, MIBK) 37.8

Example 2 In Example 1, when a wood grain pattern was printed, a foaming inhibitor was added to the ink for printing a part of the conduit pattern to form a shallow concave part of the conduit pattern for printing. A wall covering was produced.
