The rubber composition is characterized by comprises the following components in parts by weight: 30-50 parts of emulsion polymerized butadiene styrene rubber, 10-25 parts of polybutadiene rubber, 10-20 parts of environment-friendly aromatic hydrocarbon oil, 10-20 parts of H-resin, 3-8 parts of high-dispersion white carbon black, 5-10 parts of cis-butadiene rubber, 3-5 parts of protective wax, 2-5 parts of an inorganic foaming agent, 1-5 parts of an activating agent, and 1-5 parts of a hardening agent. The rubber composition disclosed by the invention is good in wet-skid resistance, good in bulging resistance and high in wetland gripping force, and provides balanced performances of wetland gripping force, rolling resistance and wear resistance for loading radial tires; besides, the rubber composition disclosed by the invention can improve the wear resistance, the tear resistance and the chunking resistance of the treads of the tires.
Description
Technical field
The present invention relates to a kind of truck radial tire tread composition, belong to tire manufacturing techniques field.
Background technology
As the doughnut of automobile important component part, be that automobile bears gravity, transmitting tractive power, damping force, steering force and bears the vitals of road surface reaction, its quality, is directly involved in personal safety as well as the property safety.Being accustomed to car tires to be divided into car tyre (Passenger Car Tire) and light card tire (LightTruck Tire) in the world, is exactly lorry and bus tire (Truck & Bus Tire) in addition; And according to the difference of tire process structure, be divided into again bias tire (Bias) and radial-ply tyre (Radil), and radial-ply tyre is divided into all steel and half steel two kinds, the lorry of more than 9.00 specifications, bus radial-ply tyre claim all-steel radial tyre substantially, and the lorry below 9.00 specifications, bus tire and car radial-ply tyre claim semi-steel radial tire.
Heavy load radial tire has the advantages such as wear-resisting, fuel-economizing, work-ing life is high, and its superior performance is subject to the favor of consumers in general day by day.Heavy load radial tire crown formula not only has direct relation with the wear resistance of tire, and also has relation with thorn resistance, rolling resistance, dry, wet and ice and snow road anti-skid etc., also plays a key effect to the security of tire, the feature of environmental protection, energy saving.Abrasion, wet and slippery, roll resistive can rational Match, heavy load radial tire can be improved and use over-all properties.Existing tire tread glue wear hardness, tire drag performance and the wet and slippery performance of tire are not very desirable; Complicated process of preparation simultaneously.
The quality of tyre performance is extremely important to automobile, and especially, under the condition that weather conditions are bad, the safety of performance to automobile of tire has vital meaning, and therefore, the doughnut that research and development have high wet-sliding resistant has demand widely.
Summary of the invention
The object of the invention is to the deficiency overcoming prior art existence, and a kind of truck radial tire tread composition is provided, there is excellent anti-slippery, agitate resistance and high wetland gripping power, give tire and give the balance quality of tire wetland gripping power/rolling resistance/wear resistance, the wear resistance of tire tread, tear resistance can be improved simultaneously and anti-ly collapse flower, fall block performance.
The present invention is achieved through the following technical solutions:
A kind of truck radial tire tread composition, comprises the component of following weight part:
Emulsion polymerized styrene butadiene rubber 40-55 part, polybutadiene rubber 5-10 part, environment-friendly aromatic oil 15-25 part, H-resin 5-15 part, high-dispersion white carbon black 5-10 part, cis-butadiene cement 3-8 part, protection wax 2-6 part, inorganic foaming agent 3-6 part, activator 2-5 part, solidifying agent 1-5 part.
Preferably, described H-resin is H-103 resin and/or H-615 resin.
Preferably, described inorganic foaming agent is any one in sodium bicarbonate, bicarbonate of ammonia.
Preferably, described activator is the mixture of zinc oxide, stearic acid, Zinic stearas, and its weight ratio is 1:1:1.
Preferably, described solidifying agent is any one in vulkacit H, hexamethoxy methyl cyanuramide or Resorcinol-vulkacit H complex compound.
The invention provides a kind of truck radial tire tread, it adopts above-mentioned rubber combination to make.
Truck radial tire tread composition of the present invention, not only has excellent anti-slippery, rolling resistance, high wetland gripping power, and has certain resistance to crack expansibility.
