    The invention relates to the production of non-combustible press materials, in particular, to a composition for impregnating cellulosic material serving to produce non-combustible press materials. The closest to the proposed technical essence and the achieved result is a composition for impregnation of cellulosic material, containing in the presence of ammonia rezol phenol-formaldehyde resin with a solids content of 50 - 80% and mol. 250-900, a plasticizer, e.g. diphenylcresyl phosphate, a hardener, e.g. hexamethylenetetramine, and a flame retardant, e.g. tetrabromobisphenol or pentabromociphenyl ether. A disadvantage of the known composition for impregnating cellulosic material is the fact that the punching strength of the pulping material is impregnated with impregnation of cellulosic material, for example, tetrabromobisphenol or pentabromociphenyl ether the basis of the press material is unsatisfactory. The purpose of the invention is to increase the ability for cold stamping of a press material obtained on the basis of the proposed composition. This goal is achieved by the fact that a composition for impregnating cellulosic material containing a resol phenol-resin-dehydrated resin obtained in the presence of ammonia with a solids content of 50-80% and mol. M., .250-900, plasticizer - diphenylcresyl phosphate, hardener - hexamethylenetetramine and flame retardant agent - tetrabromobisphenol A or penta bromodiphenyl ether, additionally contains the product of the interaction poly (ethylene glycol), polypropylene glycol and P nonylphenol with toluene-2, a-2-a, I-a, I-a, I-a, I-a, I-a, I-a, I-a, I-a, I-a, I-2 a, I-2 a, I-a, I-2, I-2, a-2, a-2. .%: ethylene glycol units 15-20; propylene glyph units 55-60; l-nonylphenol 11-15; toluene-2,4-diisocyanate 10-12, and resole-type phenol-formaldehyde resin with a molecular weight of 130,350 in the following ratio of components in terms of solid matter, wt.%: Resole-phenol-formaldehyde resin with a solids content of 50-80% and mol. m. 250-900 35-50 Diphenylcresylphosphate 20-35 - Hexamethylenetetramine 1-6 Tetrabromobisphenol A or pentabromodiphenyl ether 1-8 Interaction product of poly (glyceryl glycol), polypropylene glycol and if | -but nilphenol with toluene-2,4diisocyanatom5-20 Phenol-formaldehyde resin of the resol resolver type mol.m. 130-3501-12 The formulation is prepared by simply mixing the components. The product of the interaction of polyethylene glycol, polypropylene glycol and nilphenol | 1-foot with toluene-2,4-diisocyanate is a blocked polyetherurethane with a mol. 3000-7000 m. Press materials are made by known techniques. When this cellulosic material, preferably paper, impregnated with the proposed composition. and then the resin is condensed. Then, a few of the processed material is superimposed on each other and is pressed under the action of heat and pressure. In the case of using press materials as an electrically insulating material, for example, dL of printed circuits, separate layers are supplied with a metal foil, preferably copper, with an adhesive for hot bonding. Examples Six layers of paper impregnate specified in the table. 1 composition and then dried. The paper layers thus treated are superimposed on each other and pressed at a pressure of 120 bar at 90 bar and at a pressure of 120 bar. A 1.5 mm thick copper foil is glued onto the press material thus obtained. The properties of the press material are summarized in table. 2.. . The product of the interaction And contains, wt%: ethylene glycol units 21); propylene glycol units 57; P-nonylphenol 11; toluene-2,4-diisocyanate 12. The product of interaction B contains, in wt.%: ethylene glycol units 15; propylene glycol units 60; and nonylphenol 15; toluene2, 4-diisocyanate 10. The product of the interaction B contains, in wt.%: ethylene glycol units 20;

    propylene glycol units 55; C - nonylphenol 15; toluene-2,4-diisocyanate 10.
    Properties A, B, E and G are determined according to the German Standard DIN 40 802, property C according to the standard D 96/23. Property D is determined using a needle to make holes with a diameter of 0.8 mm. A pull force is used to force the needle to pull the needle out of the press material. Due to less punching and pulling forces, the life of the needle increases (property E).
    Ox instability is determined as follows. A sample of 12.7x102 mm vertically along the longitudinal axis is positioned so that the front edge is at a distance of 9.5 mm from the end of a Bunsen burner with a diameter of 9.5 mm. The burner is mounted on a blue flame with a length of 19 mm and for 10 s is centrically held under the lower end of the sample. After removing the flame
    182904
    the duration of afterburning or dropping is determined. After complete attenuation, the sample is re-ignited for 10 s. Duration 5 of the second afterburning or dosing is determined. Non-combustible materials are evaluated in two classes:
     class 1 - the average duration of burnout should be
    25 s; the maximum value should not exceed 30 s;
    class O - the average duration of burning out should be
    5c; maximum value should not exceed 10 s.
    As can be seen from the table. 2, the press materials treated with the composition of the invention have an increased ability to stamp in the cold state due to less stamping and output forces. Along with this, the durability of press materials during soldering is achieved.
