Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a decorative board having a coarse woven fabric such as cheesecloth adhered to its surface, and a method for manufacturing the same.

Conventionally, a decorative board having a coarse woven fabric such as cheesecloth adhered to the surface of the substrate and a printed pattern on it is known.

However, in this type of decorative board, the texture between coarse threads such as kanrei gauze forms recesses that are lower than the height of the threads.
When a printed pattern is printed using a printing roll or the like, printing ink cannot be applied between the coarse threads, and the printing ink is applied only to the threads, resulting in skipped stitches in the printed pattern.

The present invention aims to eliminate these drawbacks of the prior art.

That is, the present invention, as detailed below, compresses a foamable synthetic resin paint between coarse woven fabrics and then foams it.
This method mainly bulges out the grain of the fabric and forms an uneven pattern to create a printed pattern with a three-dimensional effect, as well as to eliminate skipped stitches in the printed pattern.

Embodiments of the present invention illustrated in the drawings will be described below.

(1) Paper 2 is adhered to the surface of substrate 1 such as plywood, hardboard, particle board, etc. via adhesive 9.

As the paper 2, colored virgin pulp, laminated paper with a pattern printed thereon, etc. are used.

Next, the woven fabric 3 is pasted onto the paper 2.

Note that the paper 2 does not necessarily need to be used.

Alternatively, the woven fabric 3 may be adhered to the paper 2 in advance and then adhered onto the substrate 1.

The woven fabric 3 is made of coarse mesh such as cheesecloth, lace-knitted fabric, or mesh fabric that allows the base material to be exposed between the grains.

(2) Next, the screen printer 7 is pressed onto the woven fabric 3 as shown in FIG. 1 (in the drawing, there is a space between the screen printer 7 and the woven fabric 3 for ease of understanding).

) Press-fit the foamed synthetic resin paint 4 onto the woven fabric 3 using the blade b on the printing machine 7, aligning it with the mesh 5 of the printing machine.

The foamed synthetic resin paint 4 includes resins such as vinyl chloride resin, urethane resin, and vinyl acetate resin, as well as plastics such as nitroso-based, sulfonic acid hydrazide-based, and ab-di-azo-based, foaming agents, pigments, stabilizers, plasticizers, etc. are mixed.

Further, the mesh of the screen printing machine 7 is shaped to match a desired pattern.

After removing the screen printer 7 from above the woven fabric 3, the paint 4 is heated and foamed.

By the way, when the paint 4 is press-fitted onto the woven fabric 3 using the screen printing machine 7, most of it is applied between the threads a and b of the woven fabric 3, and the lower surface of the printing machine 7 comes into contact with the threads a and b. Because of this, it is only applied thinly (Fig. 6).
During this period, the paint 4 mainly applied will foam.

As a result, as shown in FIG. 2, the paint 4 swells between the threads a and b, forming recesses 6 and 8.

The recess 6 is a recess in a portion corresponding to the mesh of the screen printing machine 7, and the recess 8 is a recess in a portion corresponding to the threads a and b.

In this way, an uneven pattern of the paint 4 is formed on the surface of the decorative board 1.

(6a and 8a in FIG. 6 indicate the portions that will become the recesses 6 and 8.

) (3) In addition, instead of using a screen printing machine,
A reverse roll r provided with a cut 5a as shown in the figure may be used.

In this case as well, a large amount of paint 4 is applied between the yarns a and b of the woven fabric 3, and a very thin layer is applied on the yarns a and b, so that the paint 4 is Recesses 6, 8 are formed along the roll r portion 5a which is not roughened.

(4) Furthermore, if the cloth 3 is colored or dyed in advance for makeup, or treated with clear resin to make it easier to scrape off the top coat of foamed resin paint, the amount of foamed paint between the cloth color and the grain of the cloth can be reduced. The colors can be contrasted and exposed, making it look like luxurious embroidery on the fabric using thick thread.

Furthermore, after forming the foamed coating film, if a transparent or colored transparent topcoat containing gold powder, aluminum scales, etc. is applied to the entire surface, it will not only provide optical selectivity but also make it easier to remove stains from the surface.

Furthermore, if the exposed fabric is replaced with a non-woven fabric whose bulges are integrally formed using a press, there will be no bending or shifting of the fabric, and the thickness of the vertical and horizontal threads and special weaving methods can be adjusted freely using the press mold.

Furthermore, patterns may be printed on the surface of the coating film after foaming using a gravure offset or a rubber convex roll, or the concave areas 6 and 8 of the coating film 4 may be printed.
You can also add depth to your look by adding valley print or Spanish finishing to your look.

Further, pattern matching becomes easier if the woven fabric 3 is painted or printed on the substrate 1 after the woven fabric 3 is attached to the substrate 1 rather than before the woven fabric 3 is attached.

Since the present invention has the above-mentioned principles, its functions and effects will be described as follows.

(2) Unlike the conventional method, skipping of the printed pattern between the threads a and b of the woven fabric 3 does not occur, and the printed pattern becomes a concave-convex pattern, giving it a three-dimensional design.

■ Since the manufacturing method does not require any changes to the conventional painting process, conventional equipment can be used as is.

Example 18 pieces of thin paper 2 with a light brown striped pattern printed on a light yellow-green background and treated with light purple dyeing and foaming paint penetration prevention treatment. Virgin pulp shaped into a twill weave with a grain spacing of 2 in2. The nonwoven fabric 3 is adhered with a urea adhesive.

Next, the nonwoven fabric 3 is glued onto the thin paper 2, and then applied to the surface of a 5 m/m thick plywood board 1 using a spretzer with a vinyl acetate adhesive 9.
170g/in2 and adhere.

Next, 60 pieces of pale pink unfoamed PVC plastisol 4/(
After forming a floral pattern in the coating film with uncoated areas and lightly coated areas that match the mesh of the screen by press-fitting the coating into the fabric using a mesh screen printing machine 7 of 2 inch), When the coating film is heated, since the upper part of the foamed coating film has uneven lines, a deep cloth-like decorative surface appears, which looks like a floral pattern embroidered with thick threads on the multicolored woven fabric 3.

Next, a urethane-based top clear mixed with aluminum and gold vapor-deposited flakes is applied to the entire surface of the decorative surface to provide light selection and stain prevention treatment to obtain a high-quality cloth-like decorative board. Ta.
