Embodiment 1
[0017] A low rolling resistance semi-steel radial tire tread compound formulation, characterized in that the formulation comprises the following components: 23.1 parts of emulsion polystyrene butadiene rubber, 101 parts of solution polystyrene butadiene rubber, 7.8 parts of new technology carbon black, white carbon black 67 parts, super silane coupling agent Si7476 parts, environmental protection oil 4.2 parts, zinc oxide 2.5 parts, stearic acid 1.8 parts, sulfur 1.6 parts, accelerator NS1.6 parts.
Embodiment 2
[0019] A low rolling resistance semi-steel radial tire tread compound formulation, characterized in that the formulation includes the following components: 24 parts of emulsion polystyrene butadiene rubber, 102 parts of solution polystyrene butadiene rubber, 8.7 parts of new technology carbon black, white carbon black 69 parts, super silane coupling agent Si7478 parts, environmental protection oil 6 parts, zinc oxide 2.8 parts, stearic acid 2.2 parts, sulfur 2 parts, accelerator NS 2 parts.
Embodiment 3
[0021] A low rolling resistance semi-steel radial tire tread compound formulation, characterized in that the formulation includes the following components: 25 parts of emulsion polystyrene butadiene rubber, 103 parts of solution polystyrene butadiene rubber, 10 parts of new technology carbon black, white carbon black 70 parts, super silane coupling agent Si7477 parts, environmental protection oil 5 parts, zinc oxide 3 parts, stearic acid 2 parts, sulfur 2.2 parts, accelerator NS1.8 parts.
[0022] As the above-mentioned preferred scheme, when the reinforcing agent white carbon black and the super silane coupling agent Si747 are mixed with the common coupling agent, the rebound rate of the rubber produced is increased by 20%, and the loss factor (tanδ) at 60°C Reduced by 40%, Payne effect (△G) reduced by 50%, volatile matter reduced by 80%, at the same time can reduce the Mooney viscosity, improve the dispersion performance of silica and improve the mixing efficiency.
