    1477416 A flame resistant rubber-textile product TAURUS GUMIIPARI VALLALAT 18 April 1975 [19 April 1974] 16069/75 Heading D1P A process for the production of flameproof rubber product comprises impregnating a textile material with a 9-16% of an aqueous solution of an alkali metal monophosphate salt such as sodium hydroxide phosphate representing a flame resisting substance at preferably 50-60‹C, drying the textile material and preferably stretching it simultaneously to prevent shrinkage, applying an organic solution of a fire-proofing polychloroprene mixture preferably comprising magnesium oxide and the combination of di-benzthiazil-disulphide and tetramethyl thiuroammono sulphide as cross-linking agents, whereby the textile material is cross-linked to the polychloroprene. The textile material is a transport cord. A blend of nitryl-butadiene and PVC may be used in the polychloroprene mixture wherein condensation of the nitryl-butadiene and PVC mixture takes place. The aqueous impregnation the rate of which can be adjusted to between 3-9 m/min, may also include the use of borax, and the subsequent drying can be carried out in any impregnation device used in the rubber industry or in any impregnating unit provided with a drying stage. The application of the flameproof substance can be achieved by spraying. A thin layer of the phosphate salt solution may be applied to the textile surface with the aid of rollers representing a roller stretching process. For impregnating thicker textile materials with the polychloroprene mixture a thinner and two-fold impregnation is used, while for thinner textiles a single impregnation with a concentrated solution can be used.

    The invention relates to the rubber industry, in particular to the development of a method for producing a flame retardant rubber-fabric material.
    A known method for producing flame retardant-5 of a rubber-fabric material by applying a coating based on polychloroprene rubber l on artificial silk fabric, drying and vulcanization. About
    However, this method does not allow to obtain a rubber-fabric material with high fire resistance (after removing the material from the flame, it burns for more than 2 s) while maintaining it (ad-15 hesion properties (adhesion 6–9 kg / cm).
    The purpose of the invention is to improve the fire resistance of the material. While maintaining its adhesive properties.
    The goal is achieved by the fact that, in the method of producing fire-resistant rubber-fabric material, applying a coating based on polychloroprene rubber on artificial silk fabric by drying and vulcanizing before 25 coating the fabric is treated with a 15% aqueous solution of sodium phosphate at 50-60 0 before the weight gain drying, 10-12 wt.% / m.30
    Example. In this way the fabric is belt; Artificial silk with 120 kg / cm strength is impregnated at 15% solution of 12 H, jO.
    The impregnated fabric is passed through a 15% solution at a speed of 3 m / min, and then, after weak squeezing, is dried continuously at 110-120 ° C until the moisture content is below 1%. The amount applied is 80-100 g / m, i.e. to weight gain after drying 10-12 wt.% / m.
    The fabric is initially impregnated and, as a result, becoming non-flammable in a conventional rubber industry setting, with the aim of secondary impregnation, the polychloroprene mixture is worked out at a rate of 5 m / min. After squeezing lOO-llO c and draining, the solvent is removed from the fabric.
    Further processing and vulcanization of the product is carried out in accordance with conventional production technology for belt conveyors.

    Example2. In this method, fabric of artificial silk conveyor belt with a strength of 15% growth of L, iU KG / CM is mixed by a thief Naj NRO X 12. X UN.O. () 41H.jO-, Nci,.,. 10HjO a. 1J. The fabric to be impregnated at 60 at a speed of 4 m / min is passed through a 15% solution, and then, after a slight squeeze, dried to a moisture content below 1%. The applied amount is 90-100 g / m, i.e. to gain 10-12 wt.% / m. The initially impregnated and non-flammable fabric is treated in a conventional rubber industry setting to re-impregnate with a 20% organic solution of polychloroprene mixture at a speed of 5 m / min. The solvent is removed from the fabric after squeezing at 100-110 ° C and draining. Further processing and curing is carried out according to the usual production technology for belt conveyors. With this method, the use of borax along with phosphate can have its advantage, since the borax forms solid crystals with a large surface on the surface of the fibers, with which it can improve the cross between the fibers of the fabric and the rubber systems. Example 3. Based on the economic possibilities, after the initial impregnation with an en tipiren solution according to examples 1 and 2, a mixture of nitrile-butadiene, rubber and polyvinyl chloride is used instead of polychloroprene adhesion mixture. The lining or friction mixture applied to this layer is prepared on a base of polychloroprene. Thus, the solution used according to the invention makes it possible to connect two systems, namely in such a way that the applicability of conventional tapes is not reduced, but the combination of rubber and textile fiber is very advantageous, taking into account adhesiveness and resistance to burning. The resulting laminate is characterized by high fire resistance (burning stops after the material is removed from the flame in less than 1 s) with high adhesion between the layers of 6-9 kg / cm. The invention of the method for producing a flame retardant rubber-fabric material by applying a coating based on polychloroprene rubber on a fabric of artificial silk, drying and vulcanizing, such that, in order to increase the fire resistance of the material while maintaining its adhesive properties, before coating the fabric treated with 15% aqueous solution of secondary sodium phosphate at 50-60 ° C to weight gain after drying 10-12 wt.% / m.
