ものの満足すべきものが得られていない。Flame-retardant paper is widely used as a base paper for various types of wallpaper, and is also frequently used as backing paper for vinyl wallpaper. Examples of flame-retardant paper include paper coated or impregnated with a flame-retardant substance, or paper made by wet paper-making and containing flame-retardant organic or inorganic substances in cellulose bulbs. Aluminum hydroxide-containing paper containing aluminum hydroxide in the range of 8 to 90% by weight per paper is also commonly used as a flame-retardant paper for lining vinyl wallpaper (Japanese Patent Application Laid-Open No.
-61200 and JP-A-1-266298). However, the yield rate of aluminum hydroxide in paper machines is poor, and if the content is too high, the strength of the paper (paper strength) as a flame-retardant paper is insufficient, and if the content is too low, the flame retardancy is poor, and the backing paper There is a problem that the opacity of the paper is low. Generally, vinyl wallpaper is made into a product by processing the surface of flame-retardant paper with vinyl chloride using a paste method or calendar method, and then goes through processes such as printing and embossing.
Since heat treatment at 150 to 250°C is performed during this process, if the flame retardant paper has poor heat resistance, problems such as discoloration and deformation will occur. When manufacturing wallpaper backing paper made of aluminum hydroxide-containing paper as described above, conventional methods were used to solve the problems of improving aluminum hydroxide retention, heat resistance, opacity, etc., and reducing flame retardant in paper making. Various studies have been conducted on papermaking raw materials, aluminum hydroxide, flame retardants, etc., but nothing satisfactory has been obtained.

に行うことかできる。In the present invention, a flame retardant composition is applied to a base paper having an aluminum hydroxide content of 40 to 60% by weight, which is produced by wet paper-making by mixing at least two types of aluminum hydroxide with different average particle diameters, and a flame retardant composition of 5 to 10% by weight per base paper. This is a flame-retardant paper for lining vinyl wallpaper that is coated with The raw material for base paper is bleached softwood kraft pulp (NBK).
P), hardwood bleached kraft pulp (LBKP), softwood bleached sulfide pulp (NBSP), thermomechanical pulp (TMP), and other wood valves, and one or more of these valves may be selected and mixed as appropriate. Can be used. Furthermore, dimensional stability can be improved by blending one or more types of synthetic fibers such as polyester fibers or inorganic fibers such as glass fibers into the pulp. The aluminum hydroxide used in the present invention has a purity of 99%.
It is a white powder as described above, and it is self-extinguishing because it releases crystal water and decomposes endothermically when heated. In order to impart opacity to paper, the smaller the average particle size of aluminum hydroxide, the more effective it is. However, if the average particle size is made smaller, the retention in the base paper during base paper making will decrease, and the freeness will further decrease. make worse. On the other hand, when the aluminum hydroxide content in the base paper decreases, the flame retardance of the base paper decreases. In order to solve both of these problems, in the present invention,
At least two aluminum hydroxides with different average particle sizes
Wet paper is made by mixing more than one type of paper. That is, as a result of studying the particle size of aluminum hydroxide, the following was discovered. (2) Regarding opacity, even if the average particle diameter is the same, the opacity will be improved if there are two or more peaks in the particle size distribution. 2) Furthermore, regarding the aluminum hydroxide yield and freeness in the papermaking process, even if the average particle diameter is the same, the yield and freeness are improved when there are two or more peaks in the particle size distribution. As for the aluminum hydroxide with different particle sizes used in the present invention, those with small particle sizes have an average particle size of 0.6 to
8μ■, preferably 06 to 1.0μ. If it is more than 8 μm, the opacity of the paper will be poor, and if it is less than 0.6 μm, the yield and freeness will be extremely poor, which is not desirable. On the other hand, those with a large average particle diameter are 15 to 25μ, preferably 1
It is 5 to 17μ so. If the particle size is less than 15 μm, it is undesirable because it becomes difficult to obtain a clear difference in particle size distribution when mixed with particles having a smaller particle size. however,
When mixing small and large particle sizes for the purpose of providing three or more peaks in the particle size distribution, aluminum hydroxide with an intermediate particle size, for example 8 to 15 μm, may be used in combination. Use of particles with a large particle size of 25 μm or more is undesirable in terms of surface smoothness. The mixing ratio of these aluminum hydroxides with different particle sizes is 1:1 to 1:1 by weight of those with small particle sizes and those with large particle sizes.
The ratio is 1:5, preferably 1:2 to 1:4. By increasing the ratio of particles with large particle diameters within this range, it is possible to improve the yield and freeness during paper making. On the other hand, increasing the ratio of particles with small diameters can improve the opacity of paper. The reason for limiting the aluminum hydroxide content to 40 to 60% by weight is that if it exceeds 60% by weight, the strength of the base paper will decrease rapidly. This is because flame retardancy cannot be maintained unless the amount of added substances is significantly increased. The flame retardant composition used in the present invention is a mixture of a flame retardant and a binder, and examples of flame retardants that can be used include guanidine methylol sulfamate, ammonium phosphate, red phosphorus, molybdenum, borax, and boric acid. As the binder, for example, starch, PVA, latex emulsion, etc. are used. This flame retardant composition is applied to base paper as an aqueous solution with a concentration of 5 to 20% by weight, and the amount applied is 5 to 1% per base paper.
0 weight 96 (as solid content). Application amount: 5% by weight
In the following cases, even if aluminum hydroxide is contained in an amount of 40 to 60% by weight, the flame retardance and heat resistance of the paper cannot be improved, and the paper is not suitable as a vinyl wallpaper lining paper. On the other hand, add 10 flame retardants
Applying more than % by weight is undesirable as it increases costs. The method of applying the flame retardant composition is not particularly limited as long as it can be applied uniformly, but gate roll coater-blade coater,
This can be done when making base paper on-machine using a size press or the like.
