It is widely used because of its overall good balance of performance, such as paper strength and retention of paper strength.

Ｉ・も高い、等の問題点があった。(Problem to be Solved by the Invention) Among the above-mentioned various types of paper, it is particularly used for wallpaper as a straight paper for PVC wallpaper, but for the purpose of improving productivity and streamlining, it is necessary to process it at high temperatures and for a short time. This trend is becoming stronger. That is, in addition to flame retardancy, severe heat curing conditions in the production process, e.g. 200 to 220'C
There is a need for a flame retardant that is inexpensive and has good thermal stability that can withstand the high heat of the process, and that there is little deterioration in paper strength that can lead to step 1-rubble. Although guanidine sulfamate, which has a relative performance halance as described in item 2, has almost all of these properties, it has poor thermal stability and is easily colored or discolored during the heat treatment process, which reduces its commercial value. In addition, there were problems such as high cost I.

工程が採られる。(Function) The case where the flame retardant of the present invention is used as a flame retardant for wallpaper will be described. The second stage of the "general production of wallpaper" is to roll press and dry the paper after it is made, and then roll it up as a flame-retardant paper after the drying process, and then roll the flame-retardant paper out and coat its surface with a resin. The process involves putting the material in a heat curing furnace, performing embossing, etc., and then winding it up as a product.

量部以下とするのが望ましい。The flame retardant is applied in the size press step, where the flame retardant of the present invention is impregnated and then dried to adhere and fix the flame retardant to the surface of the paper and between the fibers. Thus, flame-retardant paper treated in this manner exhibits sufficient flame retardancy. In particular, in any case, the tenth embodiments ■ to ■ are
Shows flame retardancy comparable to when guanidine sulfamate is used alone. A flame-retardant paper using potassium sulfamate alone (Aspect ①) has inferior flame retardancy than one using quanidine salt, but is superior in heat discoloration. Furthermore, when used in combination with guanisine salt, heat discoloration can be improved due to the synergistic effect without reducing flame retardancy. When used in combination, the heat discoloration is improved as the amount of potassium sulfamate increases, but there is a limit to the heat discoloration even if 100 parts by weight or more of potassium sulfamino acid is used in combination per 100 parts by weight of guanidine salt. However, since the flame retardance tends to decrease, it is preferable to use it in an amount of 100 parts by weight or less, and in particular, 5 to 60 parts by weight is most desirable because both heat discoloration and flame retardance are good and stable. Although the flame retardancy of sodium sulfamate is better than that of potassium sulfamate, its heat discoloration property is slightly inferior, but when used in combination with quanidine salt, a synergistic effect is exhibited as in the case of potassium sulfamate, and good performance can be obtained. However, since sodium sulfamate is hygroscopic, it is not preferable to use a large amount, and the amount should preferably be 80 parts by weight or less. When the kings of guanidine salt, potassium sulfamate, and helium sulfamate are used together, potassium sulfamate, which has better heat discoloration than sodium sulfamate, improves heat discoloration compared to guanidine salt alone. In addition, sodium/lium sulfamate, which has better flame retardancy than potassium sulfamate, exhibits a synergistic effect that maintains performance equivalent to that of guanidine salt alone. It is desirable that the total amount of potassium sulfamate and sodium sulfamate be 100 parts by weight or less based on 100 parts by weight of guanidine salt.

の如く特定すわば一層良好な熱安定性が得られる。In addition, in the above-mentioned PVC wallpaper production process, the wallpaper is then heated in a heat curing furnace, but discoloration or discoloration is prevented by the presence of potassium sulfamate or its methylol compound and/or sodium sulfamate or its methylol compound. In particular, when these and guanidine salts are used in combination (Aspects 1 to 2), the heat discoloration property is improved due to a synergistic effect, and the commercial value is increased. In particular, if the merging ratio is specified as described above, even better thermal stability can be obtained.

に紙が破断するようなことがない。Furthermore, in the manufacturing process mentioned above, a take-up process is unavoidable, and tensile force is applied to the paper in each process. However, when the flame retardant of the present invention is used, it is particularly effective in the dry state during high-temperature operation of a heat curing furnace. Compared to guanidine sulfamate, which exhibits excellent tear resistance, the tear resistance hardly decreases, and the paper does not break during production.

。Examples 5 and 6 are cases in which guanidine sulfamate and sodium sulfamate are used in combination, and the heat discoloration property is superior to that of Comparative Example 1, and the tear property is maintained at approximately the same level. Comparative Example 2 uses sodium sulfamate to sodium sulfamate alone, but in this case, the heat discoloration property is significantly worse. From this, it is understood that the heat discoloration property is improved due to the synergistic effect of both.

４は加熱変色性及び耐引裂性共劣る。Comparative Examples 3 and 4 used conventionally well-known magnesium sulfamate and ammonium sulfamate as flame retardants. Comparative Example 3 has excellent heat discoloration properties but is poor in tear resistance. Although not described as data, it also has high hygroscopicity, and when used in combination with guanidine sulfamate, heat discoloration property is significantly reduced. Comparative example-
No. 4 is inferior in heat discoloration and tear resistance.

ることができる。Of the above samples, potassium sulfamate and sodium sulfamate alone have inferior flame retardancy than guanidine sulfamate alone, but when used in combination with conventionally used flame retardants such as ammonium salts, It is capable of imparting sufficient flame retardancy. Furthermore, it was confirmed that the above-mentioned properties were further improved when potassium sulfamate and sodium sulfamate were converted into methylol. Other additives that can be used in combination with the flame retardant of the present invention include nitrogen-containing organic compounds such as dicyandiamide, melamine, and urea, and their methylol compounds, as well as hexamethylenetetramine.
By using these in appropriate combination, the heat discoloration property can be further improved.

て大である。(Effects of the Invention) As described above, the flame retardant of the present invention has better overall suitability than the conventional guanidine sulfamate, and potassium sulfamate and sodium sulfamate are available at low cost. By using it in combination with guanidine salt, the cost of 1-1-1 can be reduced. The present invention, which has such remarkable effects, has extremely great practical value.
以上that's all
