Abstract

The invention relates to a special semi-steel radial tire for a snow field and a preparation method thereof. The special semi-steel radial tire comprises, in parts by weight, 30 to 43 parts of natural rubber, 17 to 23 parts of butadiene rubber, 5 to 9 parts of styrene-butadiene rubber, 11 to 20 parts of white carbon black, 3 to 5 parts of a silane coupling agent, 12 to 20 parts of aromatic oil, 1.2 to 1.8 parts of an anti-aging agent, 1 to 1.6 parts of microcrystalline wax, 8 to 14 parts of functional resin, 2 to 3.6 parts of a white carbon black dispersant, 1 to 1.4 parts of an accelerator, 2 to 2.6 parts of Tall oil, 1.3 to 3.3 parts of cut 4 distillate oil, 1.5 to 2.5 parts of spindle oil, 0.8 to 1.2 parts of cut 3 distillate oil and 0.1 to 0.13 part of paraffin oil. The special semi-steel radial tire for the snow field provided by the invention is still extremely soft under the condition that the temperature is lower than 10 DEG C, and has large tire friction force and good road holding performance, so controllability and safety on smooth ice surface are greatly improved; meanwhile, the braking performance in the snow field and on the ice surface is improved; the braking distance is shortened; and an ideal traction force is brought.

Description

technical field [0001] The invention relates to a special semi-steel radial tire for snow and a preparation method thereof, belonging to the technical field of semi-steel radial tires. Background technique [0002] Tires suitable for use in snowy days can increase the grip. In colder and snow-prone places, people will use this kind of tires in winter, such as the three northeastern provinces, Russia and other European countries. [0003] It is best to use snow tires when driving on snowy roads. The tread of snow tires has more fine lines to enhance grip. Compared with ordinary tires, snow tires have a special formula to increase the friction with ice and snow roads. Its advantage is that it improves the passability and safety of ice and snow roads. [0004] However, the current special semi-steel radial tires for snow will become hard when the temperature is lower than 10°C, the tire friction will decrease, the grip will decrease, and the handling and safety on slippery ic...
