JPH02160600A - Relief forming method for pressure sensitive adhesive sheet - Google Patents

Abstract

PURPOSE:To enable a speedy and inexpensive working by a method wherein a relief cut sheet cut in a shape of a pattern, character or the like is adhered to a checkered surface, a finishing pressure sensitive adhesive sheet is adhered thereto in the manner of covering wholly the checkered surface, and a heat is applied to the surface of the finishing sheet to readjust edges according to the shape of a relief. CONSTITUTION:A relief cut sheet 2 cut in a shape of a pattern, character or the like desired to be expressed in relief is adhered to a checkered surface 1, using a pressure sensitive adhesive sheet or a shaped material. Next, a finishing pressure sensitive adhesive sheet 3 greater than the sheet 2 is adhered thereto in the manner of covering wholly the checkered surface 1, and heat is applied to the surface of the sheet 3 to readjust edges according to the shape of the relief. As a result, a level gap is generated between the checkered surface 1 and the relief cut sheet 2, whereby the relief pattern can be developed on the surface of the finishing sheet 3. Therefore, it is possible to select a design freely and to achieve a speedy and inexpensive working.

Description

Detailed Description of the Invention (Field of Industrial Application) The present invention uses an adhesive sheet or a shaped material to cut a relief cut sheet into the shape of the desired relief and a finishing adhesive sheet onto a base surface. This is a method of creating a relief by double bonding, and it relates to a relief processing method for adhesive sheets used for walls, doors, fixtures, etc. of buildings.

(Prior Art) Conventional relief methods include methods that use harmful corrosive liquid, methods that make a mold and press, and methods that carve out each piece one by one.

(Problem that the invention seeks to solve) However, all of these methods require complex technology and many work processes, making them not only time-consuming but also extremely expensive.Moreover, the work is always highly dangerous. It was something that haunted me.

Therefore, the present invention was created to solve the above-mentioned conventional problems.Compared to the conventional relief processing method, each design can be freely selected, and it is possible to reduce the time and cost. Furthermore, the number of places where relief processing can be used is increasing, and it has the potential to become popular as a universal wall covering material or finishing material in the future.This provides an extremely interesting relief processing method for adhesive sheets.

(Means for Solving the Problems) In order to achieve the above-mentioned objects, the present invention uses an adhesive sheet or a shaped material to create a relief that is cut into the shape of a desired relief design or character, etc. After adhering the cut sheet to the base surface and adhering the finishing adhesive sheet over the relief cut sheet so as to cover the entire base surface, heat processing is applied to the surface of the finishing adhesive sheet to form an edge according to the shape of the relief. It is intended to arrange the

(Function) By using the above-mentioned technical means, a level difference is created between the base surface and the relief cut sheet, and the relief shape is made to stand out on the surface of the finishing adhesive sheet. The purpose is to complete the relief while increasing the shrinkage performance and adhesive strength of the material.

(Example) Hereinafter, one embodiment of the present invention will be described based on the drawings.

The relief processing method of the adhesive sheet of the present invention is as follows: First, as shown in FIG. The sheet 2 is adhered to the base surface 1.

Next, as shown in Fig. 2, a finishing adhesive sheet 3 of about 0°3 mm, which is larger than the relief cut sheet 2 glued in Fig. 1, is glued so as to cover the entire base surface 1. do.

Thereafter, as shown in FIG. 3, the surface of the finishing pressure-sensitive adhesive sheet 3 adhered in FIG. 2 is thermally processed to adjust the edges according to the shape of the relief.

(Effects of the Invention) The present invention uses the above-mentioned processing method and uses an adhesive sheet or a shaped material to cut the relief cut sheet 2 into the shape of the relief design or character that is desired to be expressed, and then cuts the relief cut sheet 2 onto the base surface 1.
Since the finishing adhesive sheet 3 was glued on top of this relief cut sheet 2 so as to cover the entire base surface 1, a level difference was created between the base surface 1 and the relief cut sheet 2, A relief shape can be made to appear on the surface of the adhesive sheet 3. In addition, since the surface of the finishing adhesive sheet 3 is thermally processed to adjust the edges according to the shape of the relief, the shrinkage performance and adhesive strength of the finishing adhesive sheet 3 are not further increased, and the leaf can be completed. be able to.

According to the processing method of the present invention, the following effects can be obtained.

(a) The material of the base surface 1 to which the relief is applied can be selected, and there is no need to directly process the board surface.

(b) Since relief can be expressed only by sheet processing, construction time can be shortened.

(c) Can be constructed on site using existing walls and doors as they are.

(d) On the one hand, it is possible to mass produce it in a factory, but on the other hand, it is also possible to easily process each relief into a free and original design unlike any other.

(e) Compared to conventional relief processing, it can be produced at a lower cost.

(F) Since a flexible adhesive sheet is used, relief processing can be applied to base surfaces with complex shapes, including curved surfaces.

(g) Fire prevention certification can be obtained by using noncombustible materials for the adhesive sheet.

Therefore, compared to the conventional relief processing method, each design can be freely selected, and construction can be done in a short time and at a low cost.Furthermore, the number of places where relief processing can be used will increase, and it will become a universal wall covering material in the future. It is an extremely interesting processing method, as it has the potential to become popular as a finishing material.
