Problems solved by technology

Anti-aging agent 4020 is widely used in the formula of existing carcass rubber. Anti-aging agent 4020 has high price, poor adhesion performance, low hardness and tensile strength of the rubber compound, and meanwhile, the melting point of anti-aging agent 4020 is relatively high. The low is 45-51°C, prone to agglomeration

Abstract

The present invention discloses an all-steel load-carrying radial tire body rubber material composition comprising the following components: by weight, 100 parts of natural rubber, 56 parts of carbon black N326, 1 part of antioxidant 4020, 0.9-1.5 parts of antioxidant TMQ, 4.5 parts of insoluble sulfur 7020, 1.25 parts of accelerator DZ, 0.2 part of antiscorching agent CTP, 5 parts of adhesive RA65, 3 parts of adhesive GLR, and 8 parts of an active agent. The all-steel load-carrying radial tire body rubber material composition adopts the technical scheme, by combination use of the antioxidant 4020 and the antioxidant TMQ, the Mooney viscosity of the rubber material is increased, the adhesion property is enhanced, and the adhesion property is better in a ratio of antioxidant 4020 : antioxidant TMQ of 1:1.05; the melting point is improved by use of the optimized type antioxidant 4020, the agglomeration phenomenon can be effectively avoided, and the compounding and weighing operation is convenient.

Description

technical field [0001] The invention relates to a rubber material for tires, in particular to an improved all-steel radial tire carcass rubber material and a mixing method thereof. Background technique [0002] All-steel radial tires are made of steel cord for the belt layer and carcass layer, and are generally medium-duty truck tires [0003] and light duty tires. It mainly has the following advantages: 1. Wear-resistant, puncture-resistant, durable, high mileage and long service life; 2. Small rolling resistance, low fuel consumption, low heat generation, and less exhaust emissions; Comfortable vibration and stable handling. Steel wire has been widely used as a skeleton material in the belt layer and carcass layer of radial tires. In order to improve the adhesion between steel wire and rubber, it is generally plated with brass on its surface. During vulcanization, the sulfur in the compound reacts with zinc oxide and copper oxide on the surface of the coating to form Z...
