Abstract
An acid stabilized latex of natural or synthetic rubber is acidified, mixed with formaldehyde and a mixture of urea and melamine, and the resin components are then fully condensed in the latex; the rubber-resin product is separated and, if desired, vulcanized. The vulcanized product may be suitable for the manufacture of motor-car tyres. In examples the latices used are of natural rubber or of butadienestyrene copolymers, and they are stabilized by the addition of 10 per cent by volume of 20 per cent "Emulphor O" (Registered Trade Mark) solution. The weight ratio of rubber to resin preferred is 70-75 to 30-25 and of urea to melamine 75 to 25. In order to prevent premature condensation or coagulation, three separate solutions are prepared, a solution of melamine in formaldehyde of pH 10 and temperature 80-90 DEG C., a solution of urea in formaldehyde of pH 7-8 and temperature 30-50 DEG C., and an acid-stabilized latex of pH 3-7 and temperature not greater than 50 DEG C.; these three solutions are then mixed and maintained at pH 3-4 and 80-85 DEG C. for 2 hours. After being cooled, neutralized, washed and dried, the rubber-resin product may be vulcanized by such mixtures as zinc oxide, stearic acid, N-cyclo hexyl-2 benzothiazole-sulphenamide, and sulphur with Agerite Alba, phenyl-b -naphthylamine, or styphen V, for times ranging from 1/4 to 1 hour and at temperatures from 127 DEG to 142 DEG C.ALSO:An acid-stabilized latex of natural or synthetic rubber is acidified, mixed with formaldehyde and a mixture of urea and melamine, and the resin components are then fully condensed in the latex: the rubber-resin product is separated, and if desired, vulcanized.
