Abstract

The invention relates to a zero degree belt compound of all-steel radial tire, which is characterized by being prepared from a plurality of raw materials. The raw materials in formula comprises 10# natural rubber, carbon black N375, carbon black N660, hydrated silica, zinc oxide, modified alkylphenol- formaldehyde resin TKM-M, N-(1,3-dimethylbutyl)-N'-phenyl p phenylenediamine, resorcinol formaldehyde resin, cobalt boroacylate, hexamethoxy methyl melamine, N-t butyl-2-benzothiazolesulfenamide, insoluble sulfur HD OT20 and N-cyclohexylthiophthalimide. The invention is used as zero degree belt compound in all-steel radial tire production. The rubber compound of the invention has the advantages of reducing extrusion temperature of the zero degree belt, improving extrusion speed, increasing surface viscosity of the zero degree belt, prolonging holding time of viscosity, improving rubber-coating effect, and effectively solving the quality problems of point-like copper exposition and poor surface viscosity.

Description

Technical field [0001] The invention relates to a rubber compound for a zero degree belt layer of an all-steel radial tire, which is used in the production of an all-steel radial tire. Background technique [0002] The production of the zero-degree belt, the key component of all-steel radial tires, mainly adopts the extrusion method. The extrusion method is to plasticize the rubber material through the extruder screw, and rely on the mechanical force generated by the extruder head to squeeze the rubber material into the steel cord, so that the rubber material and the steel cord are organically combined into a zero degree. Belt layer. In actual use, the extrusion temperature of ordinary rubber is high, the extrusion speed is slow, the surface of the extruded zero-degree belt is not smooth, the viscosity is poor, and the phenomenon of copper exposed, which requires the production of zero-degree belt rubber should be It has lower Mooney viscosity, better fluidity, excellent self-a...
