面等に貼着することにより施工され、施工が簡単なため
広く使用されている。Conventionally, for the interior decoration of buildings, vinyl chloride resin decorative sheets (hereinafter simply referred to as vinyl chloride sheets) that have been colored, printed, embossed, etc. are pasted on walls and other surfaces. PVC sheets for wall coverings and facings that are commonly used today are pre-tacked. Tack processing refers to forming an adhesive layer on one side of a PVC sheet and laminating a separator on the layer. This tack-processed PVC sheet is constructed by peeling off the separator at the construction site and pasting the adhesive side onto a wall surface, etc., and is widely used because of its easy construction.
しかしこのようなタック加工塩ビシートにおいては、塩
ビに添加された可塑剤その他の添加剤が経時的に粘着剤
層中に移行し、粘着剤の接着性能か劣化する。However, in such tack-processed PVC sheets, plasticizers and other additives added to the PVC migrate into the adhesive layer over time, degrading the adhesive performance of the adhesive.
従って、タック加工後の製品の長期間保存は困難であり
、かつ製造後（または出荷後）の品質管理も困難である
。Therefore, it is difficult to store the product after tack processing for a long period of time, and it is also difficult to control the quality after manufacturing (or after shipping).
現在、この種のタックシートは多品種少ロット生産が一
般的であり、商品の受注後、短期間でタック加工を行い
、製品を出荷しなければならず、製造者は納期対応に苦
慮している。Currently, this type of tack sheet is generally produced in small lots of a wide variety of products, and after receiving an order for the product, tack processing must be performed and the product shipped within a short period of time, and manufacturers are struggling to meet delivery dates. There is.
さらに従来のタックシートでの施工において、施工面が

あり、改善が望まれている。Furthermore, in construction using conventional tack sheets, if the construction surface is rough, a smoothing process such as putty treatment or primer treatment is required. In such a case, there are problems such as an increase in the number of work steps, making it complicated, and a long work time, so improvements are desired.
従って本発明の目的は前記した塩ビタックシートにおけ

シートの施工方法を提供することである。Therefore, an object of the present invention is to provide a method for constructing a PVC sheet that solves the above-mentioned problems with the PVC tack sheet, allows easy storage of the product, facilitates quality control, and can be carried out using simple means. That's true.
本発明者は、上記目的を達成するため鋭意研究しこれま

。In order to achieve the above object, the present inventor conducted extensive research and departed from the idea of using a tack-processed PVC sheet, which has been common knowledge in this technical field, and, on the contrary, developed a method using a PVC sheet and an adhesive. It has been found that the above object can be achieved by separating the adhesive layer until construction is completed and then applying the adhesive layer to the construction surface or PVC sheet at the construction site.
本発明はこの知見に基づくもので、化粧シートを粘着剤

る化粧シートの施工方法である。The present invention is based on this knowledge, and in a method of applying a decorative sheet using an adhesive layer, the vinyl chloride resin decorative sheet and the adhesive layer are separated until installation, and at the time of installation, first of all, After applying the adhesive layer to the surface to be applied, the vinyl chloride resin decorative sheet is applied to the exposed surface of the adhesive layer, or the vinyl chloride resin decorative sheet is first applied to the exposed surface of the adhesive layer. This method of constructing a decorative sheet is characterized in that after an adhesive layer is attached to one side, the vinyl chloride resin decorative sheet is attached to the construction surface using the exposed surface of the adhesive layer.

工程を省略できる。The adhesive layer is preferably used as a so-called double-sided adhesive sheet, and in this case, it is particularly preferable to have a support layer as an intermediate layer. Preferably, the support layer is fabric or foam. By using a double-sided pressure-sensitive adhesive sheet having this type of support layer, the smoothing step can be omitted even when applying to rough surfaces.

好ましい。(2) Adhesive layer The thickness of the adhesive layer used in conventional products is 10-1
008m1 is generally 25 to 60 μm in particular, and an adhesive layer having this general thickness can be used in the present invention. However, in order to improve adhesion to rough surfaces, the thickness of the adhesive layer is preferably 100 μm or more. If the adhesive layer alone constitutes a thick film of 100 μm or more, adhesive physical properties such as holding power will deteriorate, so it is particularly advantageous to use a suitable support layer as an intermediate layer. For this reason, as the support layer of the double-sided pressure-sensitive adhesive sheet, for example, a flat fiber structure such as paper, nonwoven fabric, cloth, knitted fabric, etc., as well as a film, foam, etc. can be used. Or preferable.

It also has excellent tensile strength and dimensional stability, making it suitable for the present invention. Among various cloths, cotton cloth, vinylon cloth, etc. are particularly preferable because they have excellent properties.

体上のセパレーターを離型するとよい。As a method for forming the foam layer, it is desirable to form an adhesive layer on a separator, further coat a foamable resin layer thereon, and then foam the foamable resin layer. The reason is that when a foamed resin sheet is used, the tension and
This is because it tends to stretch or swell due to the effects of heat, solvents, etc., and it is difficult to coat and dry adhesive on top of it. As the foamable resin, a liquid composition is used in which a foaming agent such as water, sodium bicarbonate, azodicarbonamide, or oxybisbenzenesulfonyl hydrazide is added to the resin composition such as the polyurethane, and foaming is performed by heating. is preferred. In order to keep the thickness of the foam at a constant value, a separator is layered on top of the foamable resin coating, and after being pressed with a roller plate with a certain gap, the separator is heated and foamed. It is recommended to release the mold.

It may be μm. However, it is preferable to use a double-sided adhesive sheet provided with an intermediate support layer as described above, in which case the thickness of the adhesive layer facing the PVC sheet side and the construction side may each generally be about 25 to 60 μm. In addition, the total thickness of the adhesive layer depends on the roughness of the construction surface.
00μ or more is preferable. The adhesive layer can be formed by a known method.

効果か奏され、産業上きわめて有用である。[Effects of the Invention] According to the method of the present invention, since the PVC sheet and the adhesive are brought into contact for the first time at the construction site, there is no risk of deterioration of the adhesive layer due to migration of plasticizers and other additives, and it is not possible to use the conventional PVC sheet. Compared to tack sheets, it eliminates the complexity of the manufacturing process due to its ability to handle a wide variety of products in small lots, and it also makes quality control after manufacturing easier, and it also has the advantage of omitting the process of smoothing the construction surface. It is extremely useful industrially.
