JPS5812860B2 - Replaceable decorative plaster board - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a removable decorative gypsum board.

The conventional manufacturing method for decorative boards is to laminate a plastic sheet onto a gypsum board. A plastic sheet with arbitrary designs, designs, patterns, characters, etc. printed on the surface is directly coated with ethylene acetate vinyl on the surface of the gypsum board. Gypsum boards with decorative sheets were manufactured by laminating and bonding them using adhesives.

In other words, since the decorative sheet is laminated and integrated with the surface of the gypsum board by applying adhesive directly, if the decorative sheet becomes damaged or dirty after adhesion, it cannot be replaced and must be disposed of. If the board was subsequently bumped into, stained, or damaged, it would have to be re-installed from the base plaster board itself, which was a major undertaking.

On the other hand, unlike wheat bran paper, the upper sheet cannot be replaced as desired, which poses the problem of how to replace it when it gets old and dirty, or when changing the appearance.

In view of the above-mentioned circumstances, the present invention has been devised so that the printed upper sheet 2 can be simply and easily peeled off and replaced without requiring special skill for any reason. This decorative sheet is made by laminating and adhering a decorative sheet 1 on the surface of a gypsum board 6 with an adhesive 5 that does not harden the adhesive between the upper sheet 2 and lower thin paper 3 so that the adhesive 4 does not harden and peels off between them. It is plasterboard.

In other words, the upper decorative sheet is in a state similar to vinyl tape, and is processed so that it can be easily removed by peeling off the release layer, and special skill is required for partial or complete replacement. Anyone can do it without much effort or expense.

In this case, common rubber-based adhesives that do not harden,
Acrylic material is sufficient.

Next, to explain an example of a decorative board that can be replaced, a decorative sheet 1 with a weight of 200 g/m2 is made by adhering a vinyl chloride sheet 2 printed and embossed using a rubber adhesive 4 to a thin paper 3 using a laminator. Apply vinyl acetate adhesive (solid content: 50 g) to the surface of a 9 mm flat gypsum board 6.
/m2) 5 was adhesively laminated to produce a decorative sheet-covered gypsum board.

Next, after using this board as part of a partition wall on a trial basis to partition the wall, the upper decorative sheet was removed and replaced, but it was sufficient and easy for the average person to do without damaging the base plasterboard. Moreover, without any skill, by simply peeling off the decorative sheet from the edge, only the upper printed sheet could be peeled off in 1 to 2 minutes.

Next, a removable decorative sheet was placed on top of this using vinyl acetate adhesive to restore it to its original state.

Two to three weeks later, the same re-sticking test was repeated again to check for any problems, but no problems were found.

Claims (1)

[Claims] 1. A non-hardening adhesive 4 is placed between the upper sheet 2 and the lower thin paper 3 so that the upper sheet 2, which has any design, pattern, pattern, character, etc. printed on its surface, can be reattached freely and is peeled off between these sheets. This repositionable decorative gypsum board is made by laminating and adhering a decorative sheet 1 as described above to the surface of a gypsum board 6 with an adhesive 5 that does not peel off.
