    Abstract: 1,131,695. Rubber textile laminates. DEUTSCHE GOLDUND SILBERSCHEIDEANSTALT. 27 April, 1967 [6 July, 1966], No. 19434/67. Heading B5N. [Also in Division C3] To improve the adhesion of natural or synthetic rubber to textile fabrics, resin-forming components comprising an aldehyde or aldehyde donor and a phenol or amine are intimately mixed with a filler comprising extremely finely divided active silica and/or aluminium silicate and/or calcium silicate and/or calcium carbonate by grinding or adsorptively by applying the resin-forming components in solution in a solvent, working the resultant mixture into a rubber sheet and vulcanizing the thus prepared rubber sheet on to a textile fabric. The resinforming components are preferably resorcinol and hexamethylene tetramine, the weight ratio of resin-forming components to fillers being from 1: 5 to 5:1. Resorcinol may be ground with the filler, preferably silica, on a mill and the resulting master batch worked into a rubber mixture containing the hexamethylene tetramine. Alternatively resorcinol is applied in solution to the finely divided fillers and the resulting product is worked into the rubber mixture. The hexamethylene tetramine is either ground with the filler or applied by adsorption in the form of an aqueous solution, and the resulting product is worked into rubber with the master batch of resorcinol and silica.
