Description

  The present invention relates to a decorative sheet for wall covering that is excellent in stain resistance and also excellent in decontamination.

  In the past, pigment-based oily stains such as lipsticks and crayons and dye-based stains such as curry and soy sauce on wall decorative sheets are stains that are difficult to remove even if they are wiped off with force. As a result, the surface condition of the decorative sheet was soiled. Moreover, the surface strength of the foamed wall covering decorative sheet is low, and there is a case where damage due to a spatula occurs during construction on the wall surface.

  In order to solve the above problems, it has been proposed to form an antifouling layer with an antifouling agent on the surface of the decorative sheet for wall covering, but both water-based and oily stains are not obtained with the conventional antifouling agent. It was difficult to achieve both removal performance and scratch resistance. For example, the use of ordinary room temperature liquid silicone oil or paraffin wax can provide slipperiness to the surface of a decorative sheet for wall covering, but it has low oil stain resistance and is an antifouling treatment agent comprising a room temperature solid paraffin wax. When applied to a foaming wall decorative sheet, the foaming temperature often exceeds the melting point, and it is difficult to impart good slipperiness to the wall decorative sheet surface. Moreover, if an antifouling treatment agent containing general acrylic resin beads that can withstand the temperature during foaming is used, the removal of contamination is good, but sufficient slipperiness is imparted to the surface of the decorative sheet for wall covering. This is difficult, and the surface of the decorative sheet for wall decoration is easily damaged during the removal of contamination, and the scratch resistance is insufficient (see Patent Documents 1 to 3 above).

Particularly preferable acrylic resins are those having a solid content of 20 to 50% by mass and a glass transition temperature of 30 to 60 ° C.

  The rubber film-forming silicone emulsion is an emulsion that forms a silicone rubber film by evaporating water. For example, X-51-1309, X-51-1300, X- 51-1319, Polon MF40, etc. can be obtained and used. These emulsions can be used at a solid content of 20 to 50% by mass. The rubber film-forming silicone used in the present invention preferably has an elongation after drying of 200 to 1000%, a hardness of 10 to 100, and a tensile strength of 0.5 MPa or more. The use of such a rubber film-forming silicone is considered to be a factor in improving the scratch resistance of the coated product by giving the effect of reducing the force on the coated surface due to elasticity and imparting slipperiness due to the release property derived from silicone rubber. It is done.

  The spherical silicone rubber beads having an average particle diameter of 1 to 10 μm used above are those in which silicone rubber fine particles are dispersed in water.

Moreover, the application | coating method of the said slipping antifouling processing agent is not specifically limited, You may apply by any methods, such as spray application and roller application. The slippery antifouling layer surface thus formed maintains the high decontamination property of the substrate and has slipperiness.

[Embossing]
In the present invention, it is preferable to perform an embossing treatment after the above-mentioned slipping antifouling layer is formed. In the embossing process, a foamed wall covering decorative sheet is passed between a metal roll (embossed plate) and a rubber roll (impression cylinder) having protrusions and depressions to form protrusions and depressions on the surface of the wall covering decorative sheet. At the time of the embossing treatment, it is preferable to circulate cooling water inside the embossing roll and the impression cylinder to cool the wall covering decorative sheet simultaneously with the embossing. The heating temperature of the decorative sheet for wall decoration varies depending on the resin forming the resin layer, and is appropriately set. If the embossing temperature is too low, an appropriate uneven pattern is not formed on the surface of the decorative sheet for wall decoration, and if the embossing temperature is too high, the thickness of the decorative sheet for wall decoration after embossing is reduced, and the decorative sheet for wall decoration becomes insufficient in volume. . It is desirable that the heating during embossing be performed around the melting temperature of the resin forming the resin layer.
