This heat-sensitive delay type pressure-sensitive adhesive is a pressure-sensitive adhesive that is not tacky at room temperature, but becomes tacky by heating and lasts for a considerable period after cooling. Usually, the dry coating film (thin film layer) of this pressure-sensitive adhesive is not tacky, and release paper is unnecessary.

After once dissolved, it does not crystallize easily, so that the adhesive holding time after heat activation can be prolonged. Examples of the solid plasticizer include diphenyl phthalate, dihexyl phthalate, dicyclohexyl phthalate, dihydroabietyl phthalate, sucrose benzoate, ethylene glycol dibenzoate, tribenzoic acid glyceride, sucrose octaacetate, tricyclohexyl citrate, N An organic compound that is solid at room temperature, such as cyclohexyl-P-toluenesulfonamide.

On the other hand, the tackifier is added in an amount of 0 to 100 parts, and the solid plasticizer is added in an amount of 50 to 100 parts to prepare a heat-sensitive delay type adhesive composition. This composition is applied to the back side of the decorative sheet and dried to form the heat-sensitive delay type pressure-sensitive adhesive layer 10. Usually, the pressure-sensitive adhesive layer has a thickness of 5 to 30 μm. The heat-delayable pressure-sensitive adhesive can be applied by a known coating device such as gravure coating, knife coating, lip coating and roll coating.

ルジョンを利用して合成樹脂層１２としたものである。Further, the conventional wallpaper has P as a synthetic resin layer.
PVC wallpaper using a VC resin layer was the mainstream, but a plasticizer such as phthalic acid-based DOP is used to impart flexibility, and this plasticizer is used as a plasticizer for the heat-sensitive delay type pressure-sensitive adhesive layer. It is integrated and activates the adhesive to weaken the peeling (the peel strength becomes stronger and peeling occurs between the backing paper of the wallpaper when peeling). Therefore, the synthetic resin layer uses a resin that does not use a plasticizer, such as an aqueous acrylic resin, an acrylic / ethylene vinyl acetate copolymer (EVA) mixed resin, or an emulsion of an acrylic ester-EVA resin. Then, the synthetic resin layer 12 is formed.

A water-resistant layer was provided on the surface of the backing paper in order to prevent the so-called waving phenomenon, which is a problem that the backing paper absorbs moisture and stretches. This layer is obtained by dispersing an inorganic powder such as aluminum hydroxide in a synthetic resin emulsion such as acrylic resin (for example, TT base paper, manufactured by Tokushu Paper Co., Ltd.).

能となる。In the wallpaper or the like provided with the heat-sensitive delay type pressure-sensitive adhesive layer 10, the heat-sensitive delay type pressure-sensitive adhesive is heated by heating the entire wallpaper from the surface of the wallpaper with a heating device such as an iron or a jet dryer at the time of replacement. When the solid plasticizer of the layer is activated, this adhesive layer acts as an adhesive. That is, the adhesive bonds two objects when solidified, but it is also possible to peel the two objects before completely solidified, that is, in a liquid system. Therefore, the wallpaper can be peeled from the adhesive layer from the wall surface without destroying the backing paper.

優れた化粧シートを得ることができる。In order to prevent the migration of the plasticizer from the synthetic resin layer, the decorative sheet is manufactured by using the aqueous emulsion. Therefore, from production-construction-indoor environment-waste material treatment to waste material treatment, conventional PVC is used. It is more ecological than resin wallpaper. That is, at the time of manufacturing, since it is water-based, there is no concern about air pollution, explosion, fire, poisoning, etc. due to the solvent. Therefore, there is no need to make the machine explosion-proof and no solvent recovery facility is required. In addition, the construction and indoor environment are free of plasticizers, organic flame retardants, etc. that volatilize and pollute the room.
Safety can be guaranteed for residents. Further, when the waste agent is treated, the resin layer is made of C 2 H 2 O, and halogenated gas such as HCl is not generated even if incinerated.
An excellent decorative sheet can be obtained.
