Description

[Detailed description of the invention] The present invention relates to a novel decorative material.

Various decorative materials such as flooring materials have been proposed in the past, and some of them have been put into practical use. The main ones are those that are printed on the surface of a synthetic resin sheet such as vinyl chloride, and those that are printed on a similar sheet using foaming ink and heated and foamed to give an uneven pattern. , a combination of a foamable resin composition and a foaming suppressor or foaming accelerator. However, decorative materials manufactured by this method have problems with durability, and when used for flooring in places where many people come and go, such as department stores, supermarkets, and coffee shops, the surface of the flooring material may wear out. However, there were drawbacks such as severe loss of pattern.

The present invention has been made in order to eliminate the drawbacks of the conventional products, and it is possible to punch, press cut, or otherwise cut a decorative base material made of synthetic resin, cloth, cardboard, etc., or a composite thereof. To provide a decorative material manufactured by forming through-holes in the shape of letters or patterns using a method, pouring a resin composition colored in a desired color of the same type or different from the material into the through-holes, and then solidifying the resin composition into one piece. It is something. Next, the process of manufacturing the decorative material of the present invention will be explained in detail according to the drawings.

As shown in FIGS. 1 and 2, through holes 2 are formed in the shape of letters or patterns in a material 1 by punching, punching, or other methods.

Next, as shown in FIG. 3, a resin composition 3 colored in a desired color, which is the same as or different from the material 1, is poured into the through-hole 2, and the colored resin composition 3 remaining outside the through-hole 2 is poured into the through-hole 2. After scraping off with a squeeze 6 or other means, it is dried and solidified, and is bonded and integrated with the material 1. Material 1 can be synthetic resin such as vinyl chloride resin or polyester resin, fabric, cardboard, or a composite thereof, and its thickness is 0.3 to 5.0 W.
It is desirable to have a value around fL, but it is not limited to this range.

As a method for forming through holes 2 in the shape of letters or patterns,
Examples of methods that can be used include a method of punching using a blanking board, a method of punching with a male die and a female die, a method of cutting with a rotary blade, a method of burning out with a heated punching board, a method using a laser, and others. The resin composition 3 colored in a desired color, which is the same as or different from the material 1, is not particularly limited as long as it adheres to the material 1, such as vinyl chloride resin, polyester resin, polypropylene resin, and other synthetic resins. Examples include resin and others.

This colored resin composition 3 is colored in a different color from that of the material 1, and the same design effect as a printed pattern can be obtained depending on the color. The colored resin composition 3 may be poured into the through holes 2 using a roll coater, a gravure coater, a flow coater, or any other arbitrary method, and the colored resin composition 3 remaining outside the through holes 2 may be Scrape by squeezing or any other method.

The colored resin composition 3 is poured to fill the entire through hole 2 as shown in FIG. 4, but since the solvent and the like are removed when it dries, it is actually poured into the middle of the through hole 2 as shown in FIG. It will begin to fill up to. Next, as shown in FIG. 6, a colored resin composition 3 is applied to the middle of the through hole 2, and then a colored resin composition 3'' is applied in a different color from the colored material. If a plurality of layers with different colors are formed in the same through-hole, such as applying resin composition 3'' colored in a different color from 3'' and 3'', the upper layer can be peeled off in response to wear of the decorative material. By this, a product having several sets of color combinations can be obtained.Until the colored resin composition 3 is poured and solidified and integrated, the material 1 with the through holes formed therein is placed between a metal roll and a resin composition. Each process is carried out by placing the material in close contact with a roll or a belt coated with silicone or fluorine.Also, by repeating the above steps several times, a multi-colored, multi-tiered decorative material with good design can be obtained. You can also do it.

Further, for the purpose of reinforcement, a backing of the same kind or a different kind to the material 1 can be applied via an adhesive or the like, and depending on the performance of the backing sheet, water resistance or other performance can be added.
The decorative material of the present invention as described above has the following various effects. (1) The pattern on the surface of the decorative material is not simply applied to the surface of the material, but is formed to the same thickness as the material, so the surface has very good abrasion resistance, such as flooring. Even when used as a decorative material, both the surface pattern and surface properties of the decorative material are worn away. Continue until finished.

(2) By repeating the steps of forming through-holes and pouring the colored resin composition, the same effect as in the case of multicolor printing can be obtained.

(3) Since a plurality of layers of different colors are formed in the same through hole, by peeling off the upper layer in response to wear of the decorative material, it is possible to obtain a material having several color combinations.

(Example) A cream-colored metal drum with a thickness of 37V coated with hard chrome plating to withstand rotary blades.
! of vinyl chloride sheet is continuously supplied, and after cutting out a part of the vinyl chloride sheet in the shape of a rose flower using a rotary blade in the through hole and removing the scraps, the vinyl chloride resin colored red is removed. Apply it on the sheet and scrape off the resin other than the through holes with a Teflon squeezer 1
Heated at 80-200°C for 2 minutes.

Next, a yellow colored vinyl chloride resin was applied in the same manner to form a two-layer structure. In the same way, cut out the parts corresponding to the rose branches and pour in the vinyl chloride resin colored brown twice, then cut out the parts corresponding to the rose leaves and pour the vinyl chloride resin colored green twice in the same way. After pouring the mixture several times and finally heating it to integrate, it was lined with a 2 Tnm thick vinyl chloride sheet to obtain a decorative material.

Claims (1)

[Claims] 1. A decorative base material made of synthetic resin, fabric, cardboard, etc., or a composite thereof, and a through-hole formed in the material are filled to form a plurality of layers, which is different from the above-mentioned material, and a plurality of resin compositions each colored differently.
