Abstract

The invention discloses a solution-polymerized styrene-butadiene tread rubber and a mixing process thereof. The tread rubber comprises the components by weight: 40-220 parts of a solution-polymerized styrene-butadiene rubber, 10-60 parts of natural rubber, 5-20 parts of tread rubber powder, 1-4 parts of stearic acid, 1-2 parts of sulphur powder, 20-40 parts of white carbon black, 5-10 parts of carbon black, 2-30 parts of an aromatic hydrocarbon oil, 1-8 parts of zinc oxide, 4-7 parts of an anti-aging agent, 1-4 parts of a pine tar oil, 1-4 parts of an accelerant, 0.2-1 part of an anti-reversion agent and 2-5 parts of a bonding agent. A three-stage mixing process is employed. The tread rubber has good anti-aging performance and high wear-resistant property, can prolong service life of an automobile tyre, and has a high safety factor.

Description

technical field [0001] The invention belongs to the technical field of tire manufacture, and in particular relates to a solution-polymerized styrene-butadiene tread rubber and a mixing process thereof. Background technique [0002] Car tires generally adopt the structure of semi-steel radial tires. Semi-steel radial tires refer to radial tires whose tread parts or all use steel cords as reinforcing materials, and the carcass is made of fiber materials such as nylon and polyester. Composition of car tires: tread, cap ply, belt ply, sidewall, rim wear-resistant rubber, carcass, inner liner, bead, apex, rim protector, etc. The running speed of the tire is high, the rigidity of the crown part is high, and the thickness is thin. The tread is the part where the tire directly contacts with the road surface and bears the most severe external stress of the tire. The creep between the tread and the ground is very small, and the traction force and lateral force Higher, the frequently ...
