Abstract

The invention discloses a rubber tire tread and a milling process thereof. The rubber tire tread comprises the following components in parts by weight: 70-110 parts of natural rubber, 0-15 parts of styrene-butadiene rubber, 5-20 parts of tread rubber powder, 1.5-2.5 parts of stearic acid, 1-2 parts of sulfur powder, 2-18 parts of white carbon black, 12-15 parts of carbon block, 2-30 parts of aromatic oil, 1-8 parts of zinc oxide, 4-7 parts of an anti-aging agent, 1-4 parts of pine tar, 1-4 parts of an accelerating agent, 0.2-1 part of an anti-reversion agent and 2-5 parts of a binding agent. A three-section milling process is adopted, and the milling process can improve the abrasive resistance, tear resistance and chunking and chipping resistance of the tire tread.

Description

technical field [0001] The invention belongs to the technical field of tire manufacturing, and in particular relates to a rubber tire tread and a mixing process thereof. Background technique [0002] As an important part of the car, the car tire is an important part of the car to bear gravity, transmit traction force, braking force, steering force and bear the reaction force of the road surface. Its quality is directly related to personal and property safety. [0003] It is customary in the world to divide car tires into passenger car tires (Passenger Car Tire) and light truck tires (LightTruck Tire), in addition to truck and bus tires (Truck&Bus Tire); ) and radial tires (Radil), and radial tires are divided into two types: all-steel and semi-steel. Generally, truck and bus radial tires with specifications above 9.00 are called all-steel radial tires, and trucks, bus tires and cars with specifications below 9.00 Radial tires are called semi-steel radial tires. [0004] Ge...
