布の使用等が試みられている。2. Description of the Related Art Many decorative papers are formed by applying a surface decoration with a vinyl chloride resin paste to the surface of a backing paper made of cellulose fibers. Vinyl chloride resin is economically available, has excellent processing properties, is easy to handle, and has many properties superior to other resins in terms of weather resistance, abrasion resistance, adhesion, and the like. However, plasticizers that are blended in large amounts at the time of use are easy to bleed, which bleeds and promotes contamination of the surface of the decorative paper, and is a flammable substance similar to kerosene. It also promotes the generation of harmful halogen gas, which is problematic in that it is a carcinogenic substance. Therefore, there is a demand for decorative paper that does not use a vinyl chloride resin, that is, a vinyl chloride-free product. As a method for obtaining a vinyl chloride-free product, use of acrylic resin paste, emulsion latex, polyolefin resin, pulp / cellulose fiber nonwoven fabric, etc. instead of vinyl chloride resin paste has been attempted.

されて難燃性化粧用紙は得られない。The acrylic resin paste as a substitute for the vinyl chloride resin paste does not generate a halogen gas, but requires a large amount of a plasticizer like the vinyl chloride resin paste. It is costly and its use is not economical. In addition, a tough coating film is not formed depending on the emulsion latex, and a decorative paper satisfying the durability cannot be obtained. The polyolefin resin emits a very small amount of smoke at the time of combustion and is suitable for making a decorative paper flame-retardant. However, it is not practical in that it has no adhesiveness, is difficult to print, and is easily deteriorated by light. And even if the pulp / cellulose fiber non-woven fabric can be reinforced with an emulsion latex or other resin, the amount of smoke generated at the time of combustion increases due to the resin used, and flame retardancy is inhibited, so that a flame-retardant decorative paper cannot be obtained. .

Is hot melted and extruded from a blow extruder or a T-die extruder to be molded. By doing so, a resin film containing no plasticizer is obtained. It is preferable to use a nylon resin, a polyester resin, or a polyacrylate resin for the resin film. If a polyacrylate or nylon resin is used, it is extruded from the extruder and heat fused to the flame retardant backing paper. Therefore, it is not necessary to use an adhesive for bonding the resin film and the flame-retardant backing paper.
In that case, print is applied to the surface of the flame-retardant backing paper.
When the thickness of the resin film is 10 to 30 μm, the unevenness by the embossing roller can be sharpened thereafter, and the color of a print that appears on the surface through the resin film can be made vivid. for that purpose,

反応を完結させる。Polyester resin has a higher softening point than polyacrylate resin and nylon resin. However, when the film is made 25 to 100 μm in thickness and bonded with a cross-linking adhesive, the embossed roller can sharpen unevenness. Also, since the polyester resin has a lower refractive index than the polyacrylate resin and nylon resin, even if the film is relatively thick, the color of the print is not damaged by the polyester resin film, On the contrary, it is convenient because the color is deepened and the color becomes deeper. After laminating the resin film and the flame-retardant backing paper, the film is wound into a roll and cured by heating to complete the crosslinking reaction of the adhesive.

A vehicle such as polyacrylate, nitrocellulose, polyester, or melamine is applied to adjust the gloss of the surface. Among them, when a fluorine-based gloss modifier or a polyurethane-based gloss modifier is used, the feel of the surface of the resin film becomes natural as in the case of cellulose fiber paper. Gloss modifiers include mica, silica, alumina, diatomaceous earth, silica sand,

地調地模様をプリントする場合も同様である。The concavo-convex pattern by the embossing roller may be a solid color pattern such as a wood pattern, a stone pattern, a marbled pattern, a cloth pattern, a spot pattern, and a satin pattern. It is convenient for these solid-colored tones to be formed by engraving a resin film bonded to a flame-retardant backing paper through a plurality of embossing rolls, since fine and fine irregularities are formed on the entire surface. In the case where the unevenness due to the embossing roller is made into a solid color pattern, it is preferable that the print pattern is similarly made a solid color pattern. Then, for example, when embossing a satin pattern on a pipe wood grain print pattern, those plain coloration patterns are compounded, and even if the unevenness by the embossing roll and the wood grain of the printed pipe do not overlap, did the wood grain of the pipe be carved by the embossing roll? Thus, decorative paper having a three-dimensional effect can be obtained. Therefore, when the pipe grain pattern is printed, the uneven pattern by the embossing roller does not need to be the pipe grain pattern like the print, and other plain patterns such as a stone pattern, a marbled pattern, a cloth pattern, a spot pattern, and a satin pattern are used. Fine pattern is fine. The same applies to the case of printing a solid color pattern such as a stone pattern, a marbled pattern, a cloth pattern, a spot pattern, and a satin pattern.

推奨される。In the present invention, the water-containing inorganic compound is preferably 50 to
The reason for using papermaking paper containing 90% by weight is that a hydrous inorganic compound such as aluminum hydroxide is a kind of flame retardant,
Thereby, a flammable resin film of nylon, polyester, polyacrylate or the like is made flame-retardant to obtain a flame-retardant decorative paper. That is, the flame-retardant backing paper is used as a flame retardant for the resin film. For that purpose, the weight ratio of the flame-retardant backing paper in the decorative paper is as much as possible than the weight ratio of the resin film, and the weight ratio of both is such that the weight of the resin film is 50 or less of the resin film with respect to the flame-retardant backing paper 100. Preferably, it is set to 10 to 40.
Specifically, the basis weight of the flame-retardant backing paper is 120 to 200 g.
f / m 2 , while the thickness of the resin film is 10 to 1
Set to 00 μm. The basis weight of the flame-retardant backing paper is 200 gf / m 2
The reason for this is that if the basis weight of the flame-retardant backing paper exceeds 200 gf / m 2 , in-layer peeling is likely to occur, and the durability of the decorative paper will be impaired. Also, in order to make the uneven pattern by the embossing roller fine and dense, and to engrave sharply so deeply that the unevenness appears on the back side, the basis weight of the flame-retardant backing paper is 200 gf / m 2 or less, and the thickness of the resin film is 80 μm. The following is assumed. On the other hand, in order to secure the shape stability of the uneven pattern and the concealability of the decorative paper, the basis weight of the flame-retardant backing paper should be 60 gf / m 2 or more, and the thickness of the resin film should be 10 g / m 2 or more.
μm or more. The basis weight of the flame-retardant backing paper is 60 g
When f / m 2 or more, the decorative paper has excellent concealing properties,
It is also suitable for wall-covered grounds, and its adhesive construction hides the groundwork of the wall surface, allowing the wall surface to be beautifully dressed. Therefore, it is recommended that the basis weight of the flame-retardant backing paper be 120 to 200 gf / m 2 in order to use the decorative paper as the wall covering.

られる。The hydrated inorganic compound which occupies the majority of the flame-retardant backing paper as the base of the decorative paper of the present invention is a mineral fine particle having no adhesive property, and is entangled with cellulose fibers which maintain the shape of the flame-retardant backing paper. Is low. For this reason, when passing through an embossing roll, mineral fine particles such as aluminum hydroxide are separated from each other, and the cellulose fibers are also separated from the mineral fine particles, so that fine cracks are easily generated in the flame-retardant backing paper. Therefore, the embossed roller can be finely and finely carved on the decorative paper so that the concavo-convex pattern is fine and dense and the concavity and convexity appear on the back surface. However, the resin film does not contain a plasticizer, and is resin-rich and tough. Therefore, even when the thickness is 30 μm or less, the flame-retardant backing paper does not crack even when it passes through an embossing roll, and a decorative paper suitable for a wall-covered material having a tough surface and high abrasion resistance can be obtained. .

化粧用紙が得られる。Even if the surface of the flame-retardant backing paper is covered with a resin-rich resin film, the front and back surfaces are carved, and the surface is also formed of a thin film of a gloss modifier. Because it is covered, it does not have the glossy luster peculiar to the resin film, and it is possible to obtain a decorative paper suitable for a wall-covered fabric having a soft touch like pulp fiber paper.

着して剥離・展開が不能になることはない。Since a tough, water-impermeable resin film is interposed inside the decorative paper, the application glue is applied to be applied to a wall or the like for application, and even when folded and cured, the application adhesive is applied. There is no possibility that the applied surfaces (back surfaces) adhere to each other after drying and peeling / deployment becomes impossible.

性を妨げるような不都合も生じない。The resin film does not contain a plasticizer, and the plasticizer does not promote the burning of decorative paper. Also, since the weight of the flame-retardant backing paper is higher than that of the resin film, the decorative paper becomes flame-retardant, and the plasticizer oozes out on the surface to promote contamination, and oozes out on the back side to adhere the glue. There is no inconvenience that hinders the performance.

The amount of decorative paper does not increase due to the adhesive, the flame-retardant backing paper and the resin film do not come off, the production process yield is good, and the cost of decorative paper can be reduced.

The extruded surface can be embossed at the same time as the extrusion when the film is in the heat-melted state, and no adhesive is required for bonding the flame-retardant backing paper and the resin film, and the resin film can be made extremely thin with a thickness of 10 to 30 μm. As a result, the flame-retardant performance of the flame-retardant backing paper is not affected by the resin film, and a flame-retardant decorative paper can be easily obtained.
