(Industrial Application Field) The present invention relates to improvements in flame retardant treatment agents. The flame retardant treatment agent of the present invention is used for flame retardant treatment of mainly cellulose materials such as wallpaper, fusuma paper, shoji paper and other paper materials, wood plywood, wood, cellulose fibers, etc. (Prior Art) Ammonium sulfamate, guanidine sulfamate, and the like are used as softening agents and flameproofing agents for paper materials such as wallpaper, fusuma paper, and shoji paper. (Problems to be Solved by the Invention) However, paper materials treated with ammonium sulfamate tend to become colored when heated, and guanidine sulfamate does not have sufficient flame retardant ability. It is an object of the present invention to provide a flame retardant treatment agent that imparts flame retardant properties to cellulosic materials, and another object of the present invention is to provide a flame retardant treatment agent that imparts flame retardant properties to cellulosic materials. Another object of the present invention is to provide a flame retardant treatment agent that does not cause coloring. (Means for Solving the Problems) The flame retardant treatment agent for cellulosic materials of the present invention is characterized in that it is prepared by adding methylolmelamine to an aqueous solution of aluminum sulfamate and heating it. The objects to which the flame retardant treatment agent of the present invention is applied are materials made of cellulose and processed products thereof,
Examples include paper, wood, fibers, and processed products thereof such as wallpaper, fusuma paper, shoji paper, and wood plywood. An aqueous solution of aluminum sulfamate can be easily obtained not only by dissolving aluminum sulfamate in water but also by dissolving sulfamic acid and aluminum powder in water. The molar ratio of sulfamic acid to aluminum in this aqueous solution was 3.0:1. When the aqueous solution of aluminum sulfamate is obtained by dissolving sulfamic acid and aluminum in water, by dissolving both components in the above molar ratio,
Sulfamic acid is precipitated by concentrating an aqueous solution containing an excess of sulfamic acid with a molar ratio of 3 or more and is removed from the solution, or sulfamic acid is added to an aqueous solution lacking sulfamic acid with a molar ratio of 3 or less. It can be easily obtained by dissolving it. The aqueous solution of aluminum sulfamate is usually preferably used as a 5 to 40% by weight solution. Methylolmelamine is easily obtained in a conventional manner, for example by reacting melamine with formaldehyde in water, and is usually used as an aqueous solution. The amount of methylolmelamine added to the aqueous solution of aluminum sulfamate is preferably about 100 to 200 parts by weight of methylolmelamine solid content per 100 parts by weight of aluminum solid content. The flameproofing agent of the present invention can be obtained by adding methylolmelamine to an aqueous solution of aluminum sulfamate and heating the solution as described above. The heating temperature is about 50 to 80°C, and usually within several hours. (Effect) This heating yields a stable flame retardant, but it is likely that the methylol group of methylolmelamine reacts with the -NH2 group of sulfamic acid, and -
This is thought to be due to the formation of an addition compound due to the NH--CH 2 -- bond. In addition, the atomic group of methylolmelamine has a high affinity for cellulose materials, and the adhesion of the flame retardant treated to cellulose materials to cellulose improves, thereby achieving a preferable flame retardant treatment. Conceivable. (Example) 1030g of water, 105g of sulfamic acid and 10.8
g of aluminum powder was added and heated at 60 to 70° C. with stirring to obtain an aqueous solution (2) having a molar ratio of sulfamic acid groups to aluminum ions of 2.7:1. Next, by further dissolving 3 g of sulfamic acid in 300 g of the above aqueous solution (), the molar ratio of sulfamic acid groups to aluminum ions was adjusted to 3.0:
An aqueous solution of aluminum sulfamate (1) was obtained. Separately, 39.4 g of an aqueous solution of 55.8% by weight methylol melamine adjusted at a molar ratio of melamine:formaldehyde of 1:3 and 289 g of the above aluminum sulfamate aqueous solution () were mixed and stirred,
The flameproofing agent of the present invention was obtained by heating at 60°C for 2.5 hours. Next, a filter paper for chemical experiments was immersed in the above flameproofing agent and then dried to obtain a filter paper subjected to flameproofing treatment. The flexibility of the filter paper obtained here was almost the same as before soaking. Next, the coating amount, flame retardance and heat resistance were tested according to the following test methods, and the results shown in Table 1 were obtained. (1) Flame retardant test method Based on JIS-Z-2150 method. However, the heating time was 10 seconds. (2) Heat resistance test method After heating at 170℃ for 5 minutes in a hot air circulation dryer, take it out and visually observe the degree of coloration. (3) Amount of treatment agent attached Calculated from the difference in weight of each filter paper before and after treatment. In Table 1, ◎ indicates that almost no coloring is observed; ◯ indicates light yellow coloring; and × indicates brown coloring. Comparative Example A test was conducted in the same manner as in the example except that a 10% by weight aqueous solution of ammonium sulfamate (treatment agent A), a 10% by weight aqueous solution of guanidine sulfamate (treatment agent B), and the above aqueous aluminum sulfamate solution () were used. However, the results shown in Table 1 were obtained. From the test results in Table 1, it is recognized that the flame retardant treatment agent of the present invention imparts excellent flame retardant performance to paper materials.

[Table] (Effects of the Invention) When the treatment agent of the present invention is applied to cellulose-based materials, high flame retardant performance can be imparted to the cellulose materials. The treatment method is also simple, and is usually carried out by a spray method, a size press method, a dipping method, etc., but it is not particularly limited to these methods and any method may be used. By adhering, adsorbing or impregnating about 5 to 50% by weight, preferably 15 to 35% by weight, and drying, a flameproofed material can be obtained.
