The present invention relates primarily to flame retardants for use in paper. Conventional flame retardants for paper include guanidine sulfamate. However, these flame retardants do not exhibit their effects unless added in large amounts, and there is a problem in that flame retardant-treated paper becomes colored when heated. On the other hand, the polyethylene polyamine or ethylene diamine phosphate described in Japanese Patent Publication No. 49-32754 exhibits excellent flame retardancy, but when paper coated with the amine phosphate is heat-treated, its coloration is reduced. There were some notable drawbacks. The present inventors have conducted various studies in order to solve the above-mentioned drawbacks of amine phosphates, and have found that amine phosphates contain hydrazine compounds and/or boric acid compounds, or even formic acid, phosphorous acid, and hypophosphorous acid. The present invention has been completed by discovering that by mixing one or more of these salts, the coloration during heat treatment can be suppressed to a level that is minimal or minimal and poses no problem in practical use, without reducing flame retardancy. I've reached it. The amine phosphate in the present invention is ethylenediamine or its condensate, for example, H 2 N-(CH 2 CH 2 NH) o -H (in terms of flame retardancy, n=
1-5 is good. ) HN-(C 2 H 4 ) 2 NH, HN(C 2 H 4 ) 2 NC 2 H 4 NH 2 and one or more amines are reacted with phosphoric acid. The reaction ratio of amine and phosphoric acid is not particularly limited, but PH7 is recommended because it has little effect on paper and has high solubility in water.
Preferably, it is adjusted back and forth. Examples of the hydrazine compound used in the present invention include hydrazine hydrate, hydrazine sulfate, and hydrazine acetate. These may be used alone or in combination of two or more. The mixing amount of these hydrazine compounds is 1
It is preferably 0.1 part by weight or more. Examples of boric acid compounds include boric acid and sodium borate, which may be used alone or in combination of two or more. The amount of the boric acid compound to be mixed is preferably 0.2 parts by weight or more per 1 part by weight of the amine phosphate, but if more than 0.8 parts by weight is mixed, the paper will harden and its texture will deteriorate. Addition of formic acid, phosphorous acid, hypophosphorous acid, or a salt thereof has the effect of reducing the amount of hydrazine compound mixed, and when used together with a boric acid compound, coloring can be further suppressed. Salts with high solubility in water, such as sodium salts, are preferred, and the mixing amount is approximately 1 part by weight of the amine phosphate.
It is preferably 0.1 part by weight or more. The adhesion rate of the above flame retardant is sufficiently effective even at 10%, compared to 18% or more for conventional guanidine sulfamate. This flame retardant can be produced as follows. That is, one method is to dissolve or mix a hydrazine compound and/or a boric acid compound in an aqueous phosphoric acid solution or slurry of an amine to form a slurry, or to add formic acid, phosphorous acid,
Hypophosphorous acid or a salt thereof is added to form a liquid or slurry.Another method is to separate the amine phosphate crystals precipitated from a solvent such as water or alcohol, and then dry the crystals, which are then mixed with hydrazine sulfate, etc. A solid hydrazine compound and/or a boric acid compound, or a salt of formic acid, phosphorous acid, or hypophosphorous acid is mixed to form a powder.
There is no discernible difference in the effectiveness of these three types of flame retardants: liquid, slurry, and powder. The present invention will be specifically explained below using Examples. Example 1 134 ml of water and 75 wt% phosphoric acid in a 500 ml flask
While stirring, 49 g of an aqueous solution of ethylenediamine with a concentration of 50 wt% was gradually added dropwise. The reaction was completed in about 20 minutes while cooling the solution so that the temperature did not exceed 60°C. To this were added 13 g of hydrazine hydrate (NH 2 NH 2 .H 2 O) manufactured by Wako Pure Chemical Industries, Ltd. and 39 g of boric acid (H 3 BO 3 ) manufactured by Kanto Chemical Co., Ltd. 25 g of the resulting transparent liquid was taken, diluted with 60 ml of water, and 5A paper manufactured by Toyo Shi Co., Ltd. was immersed in the liquid, followed by drying in a dryer kept at 70° C. for 30 minutes. The paper was heated at 180℃ and 200℃ for 3 times each.
The mixture was heated for a minute and its colorability was observed. Furthermore, its flame retardant effect was also investigated. The results are shown in Table-3. Examples 2 to 6 Coloring properties and flame retardant effects were tested in the same manner as in Example 1, except that the flame retardant was adjusted as shown in Table 1. The results are shown in Table-3. In each case, a 50 wt% aqueous solution of the amine was used.
