点を有している。2. Description of the Related Art Fireproofing is required for building interior materials such as wallpaper from the viewpoint of fire safety, and there are many cases where a certain level of fireproofing is required by the Building Standards Law. Also,
Architectural interior materials are required to have high design properties in order to enhance the comfort as a living space in the room. Particularly, in order to have a three-dimensional design, materials that can not only be flexible but also highly foamable are advantageous. Becomes As a material that can meet such demands, a material using a vinyl chloride resin has been widely used. However, resin compositions containing halogens, such as vinyl chloride resins, have the drawback of generating harmful gases during fires and incineration.

発泡特性が損なわれ、発泡倍率の小さいボリューム感の
少ないものであった。[0003] For this reason, building interior materials made of a resin containing no halogen have been developed. In such a case, the resin itself is not flame-retardant, so it is necessary to impart flame retardancy, and the resin is toxic at the time of fire or combustion. Metal hydroxides such as aluminum hydroxide and magnesium hydroxide are generally used as low-smoke, non-polluting flame retardants that do not generate any gas. However, these metal hydroxides need to be highly filled in order to increase the flame retardancy, so that the fluidity of the resin during the hot melt extrusion processing is low, and a sheet with a good surface state cannot be obtained. . In addition, it is conceivable to increase the processing temperature to mold the resin in order to increase the fluidity of the resin.However, since the foaming agent starts to decompose during processing by increasing the processing temperature, there is a problem in the stability of the production process. In addition, the original foaming characteristics of the resin were impaired, and the foaming ratio was small and the volume feeling was small.

There is a problem that the surface properties are weakened and the surface of the decorative sheet is easily broken.

られる。Means for Solving the Problems To achieve the above object, a solution of the present invention is to provide a decorative sheet having a foamed resin layer, a non-foamed resin layer and a decorative layer sequentially provided on a base material layer.

A melt flow rate (hereinafter, referred to as MFR) containing a foaming agent and a silicone-based flame retardant on the base material layer 2 is 10 to 7
A silicone-based flame retardant and at least 10 to 30 parts by weight of mica were added to a foamed resin layer 3 mainly composed of an olefin-based thermoplastic resin of 0 g / 10 min and an olefin-based thermoplastic resin having an MFR of 10 to 70 g / 10 min. The non-foamed resin layer 4 and the decorative layer 5 are sequentially laminated, and the uneven pattern 6 is applied from the decorative layer 5 side to the foamed resin layer 3. By forming the foamed resin layer 3 and the non-foamed resin layer 4 in this manner, since the foamed layer does not appear, the foaming efficiency of the foamed resin layer can be increased, and the uniformity of the foamed cells is small with little variation. A foam layer having a shape can be obtained. Further, the non-foamed resin layer 4 can provide a decorative sheet having excellent physical properties such as surface scratch resistance and abrasion resistance.

でき良好な加工性を得られる。Next, the foamed resin layer 3 and the non-foamed resin layer 4 will be described. As the olefinic thermoplastic resin forming the foamed resin layer 3 and the non-foamed resin layer 4, for example, one kind of polyolefin such as polyethylene, polypropylene, polybutene, polybutadiene, polyisoprene or ethylene, propylene, butene, butadiene, isoprene, etc. A copolymer of two or more olefins, a copolymer of α-olefins having 4 or more carbon atoms (linear low-density polyethylene), an ethylene-acrylic acid copolymer, and an ethylene-methyl acrylate copolymer , Ethylene-
Ethyl acrylate copolymer, ethylene-methacrylic acid copolymer, ethylene-vinyl acetate copolymer, saponified ethylene-vinyl acetate copolymer, or ionomer,
Alternatively, a mixed resin composed of one or more of these may be used. Among them, in particular, the ethylene-vinyl acetate copolymer has a different oxygen index depending on the vinyl acetate content, and the higher the vinyl acetate content, the higher the oxygen index. Therefore, as the olefinic thermoplastic resin forming the foamed resin layer 3 and the non-foamed resin layer 4 of the decorative sheet 1 of the present invention, an ethylene-vinyl acetate copolymer is preferable, and the content of vinyl acetate is 5% or more. By doing so, the heat of combustion of the resin is reduced, which is preferable in terms of flame retardancy. Also,
By setting the content to 45% or less, the adhesion to a processing machine can be appropriately suppressed, and good workability can be obtained.

The processing temperature of 0 g / 10 min when it is heated and melt-extruded by a T-die extruder can be made lower than the decomposition temperature of the foaming agent used in the present invention, and the production process is stable, which is preferable. Further, when the MFR value is 10 g / 10 minutes or less, the compounded resin becomes hard, and even if it is a foamed resin layer, it is easily broken when bent. On the other hand, if it is more than 70 g / 10 minutes, it will be too soft, resulting in stickiness of the surface, crushing of the foam cell layer, and insufficient strength of the surface.

Azodicarbonamide, azobisformamide, etc., because they have a small heat of decomposition, are excellent in flame retardancy and self-extinguishing properties, are stable in water, are non-toxic, and can impart flame retardancy to the foamed resin layer 3. The thermal decomposition type foaming agent of the azo compound is suitable. Azodicarbonamide has a high decomposition temperature,
The combined use of a foaming accelerator is preferable because the decomposition temperature can be lowered. As the foaming accelerator, inorganic salt-based, metal soap-based, and acids are used. The amount of the foaming agent to be added may be appropriately determined depending on the required design properties, but it is generally appropriate to use 2 to 10 parts by weight based on 100 parts by weight of the ethylene-vinyl acetate copolymer forming the foamed resin layer 3.

It is preferable that a flame retardant can be effectively imparted with a small amount by adding a flame retardant, and a silicone flame retardant is extremely effective. This is preferable because the melt tension during the resin foaming) is stable and the foam cell becomes dense, and specifically, a polydimethylsiloxane alone or a mixture of a polydimethylsiloxane derivative having an epoxy group or a methacrylate group and silicon dioxide is preferred. preferable. Also, by using 100% of a silicone-based flame retardant,
The flame retardancy can be sufficiently imparted by 30 parts by weight with respect to 100 parts by weight of the resin forming the flame retardant layer. However, since the silicone flame retardant is expensive, one silicone flame retardant is used.
It cannot be used at 00% and must be used in combination with other environmentally friendly flame retardants. As the flame retardant used in combination with the silicone flame retardant, inorganic flame retardants, specifically, mica,
It is appropriate to use a mixture of one or more of inorganic substances such as aluminum hydroxide, magnesium hydroxide and calcium carbonate for the above reason.
