Embodiment 1

[0027] A kind of rubber for tires, the rubber includes the following components in weight percentage: 6% of natural rubber, 11.25% of butadiene rubber, 12% of styrene-butadiene rubber, 13% of carbon black N339, 12% of carbon black N220, and 0.5% of tackifying resin , Antiaging agent RD 0.5%, Antiaging agent BLE 0.5%, Antiaging agent 7F 1%, Microcrystalline wax 0.5%, Vulcanizing agent accelerator 2%. The remaining additives are 40.75%. The additives are various components commonly used in the rubber field, mainly zinc oxide, stearic acid, processing aids, reclaimed rubber powder, and a mixture of one or more of aromatic oils. It is an additive mainly used to improve the processing performance and use performance of rubber. It can increase the plasticity of the rubber, reduce the viscosity of the rubber and the temperature during mixing, improve the dispersion and mixing, and increase the tensile strength of the vulcanized rubber. elongation and abrasion resistance.

Abstract

Tire rubber comprises the (by weight percentage) natural rubber 6-10, polybutadiene rubber 11.25-18.85, styrene-butadiene rubber 12-20, black N339 13-17, black N220 12-17, tackifying resin 0.5-1.5%, anti-aging agent RD 0.5-1.5, anti-aging agent BLE 0.5-1.5, anti-aging agent 7F 1-3, microcrystalline wax 0.5-1.2, and curing agent accelerator 2-4. The product has high tensile strength properties and wear resistance at the same time, excellent flex fatigue resistance, prolonged the service life of the product, and reduced use cost. In addition, tackifying resin is added, to ensure the rubber adhesion, for further increasing tensile strength coefficient.

Description

technical field [0001] The invention relates to a rubber, in particular to a tire rubber and a preparation method thereof. Background technique [0002] Tires are often used under complex and harsh conditions, and they are subjected to various deformations, loads, forces, and high and low temperature effects during driving, so they must have high load-bearing performance, traction performance, and cushioning performance. At the same time, it is also required to have high wear resistance and flex resistance, as well as low rolling resistance and heat generation. Half of the world's rubber consumption is used for tire production. In order to ensure the bearing capacity and service life of tires, vehicle tires are generally required to have good wear resistance and tensile properties. [0003] The characteristics that tire rubber should have include good wear resistance, good flexibility and good adhesion to fiber materials, etc. Previously, the performance of this type of pro...
