Abstract
The invention relates to the field of vehicle tires, in particular to a tread rubber compound and a tire thereof. The tread rubber compound disclosed by the invention comprises an upper layer tread rubber compound and a low layer tread rubber compound, wherein the upper layer tread rubber compound comprises the following components in parts by weight of 100 parts of first rubber, 10-50 parts of first carbon black, 20-60 parts of first white carbon black, and 10-50 parts of first environmental-friendly operating oil; the lower layer tread rubber compound comprises the following components in parts by weight of 100 parts of second rubber, 50-80 parts of second carbon black, 10-30 parts of second white carbon black and 5-30 parts of second environmental-friendly operating oil; the first rubber comprises first natural rubber, first butadiene rubber and solution polymerized styrene nutadiene rubber; and the second rubber comprises second natural rubber, second butadiene rubber and styrene-butadiene rubber. The tread rubber compound and the tire thereof provided by the invention effectively solve the technical problems that for a conventional winter tire, endurance passing properties, wear-resisting properties and operating properties are difficult to realize.
Description
technical field [0001] The invention relates to the field of vehicle tires, in particular to a tread rubber compound and a tire thereof. Background technique [0002] In order to improve the driving safety of vehicles in winter, many countries have introduced regulations for the mandatory use of winter tires. However, after winter tires come into contact with ice and snow roads, a layer of water film is usually formed, which increases the hardness of the tires, reduces the friction between the tires and the road surface, and causes the tires to slip, thereby reducing the driving safety of the vehicle. Therefore, existing winter tires reduce skidding and improve safety by reducing the tread hardness of winter tires to increase the frictional force between tires and ice and snow road surfaces. When the hardness of winter tires is low, the durability and handling of the tires will be reduced, which will affect the driving safety of the vehicle. [0003] Therefore, how to make...
