Embodiment 1

[0017] This embodiment provides a high-strength low-temperature resistant pneumatic tire, such as figure 1 It includes an annular tread 1 and sidewalls 2 surrounding both sides of the inner wall of the tread. The tread and the sidewalls form an inner tube accommodating cavity; an annular pneumatic inner tube 3 is arranged in the inner tube accommodating cavity. The inner side of the inner tube is also provided with an elastic buffer layer 4, the inner wall of the elastic buffer layer is flush with the inner edge of the sidewall.

[0018] The thickness ratio of the pneumatic inner tube to the elastic buffer layer is 1:0.9.

[0019] The tread and the sidewall are made of commercially available vulcanized rubber by injection molding.

[0020] The pneumatic inner tube and the elastic buffer layer are made of commercially available styrene-butadiene rubber.

Embodiment 2

[0022] This embodiment provides a high-strength low-temperature-resistant pneumatic tire, which includes an annular tread and sidewalls surrounding both sides of the inner wall of the tread, and the tread and sidewalls form an inner tube accommodation cavity; the inner tube accommodation cavity A ring-shaped pneumatic inner tube is arranged in the inner tube, and an elastic buffer layer is provided on the inner side of the pneumatic inner tube, and the inner wall of the elastic buffer layer is flush with the inner edge of the sidewall.

[0023] The thickness ratio of the pneumatic inner tube to the elastic buffer layer is 1:1.1.

[0024] The tread and the sidewall are made of commercially available vulcanized rubber by injection molding.

[0025] The pneumatic inner tube and the elastic buffer layer are made of commercially available styrene-butadiene rubber.

Embodiment 3

[0027] This embodiment provides a high-strength low-temperature-resistant pneumatic tire, which includes an annular tread and sidewalls surrounding both sides of the inner wall of the tread, and the tread and sidewalls form an inner tube accommodation cavity; the inner tube accommodation cavity A ring-shaped pneumatic inner tube is arranged in the inner tube, and an elastic buffer layer is provided on the inner side of the pneumatic inner tube, and the inner wall of the elastic buffer layer is flush with the inner edge of the sidewall.

[0028] The thickness ratio of the pneumatic inner tube to the elastic buffer layer is 1:0.9.

[0029] The raw materials of the elastic buffer layer include 62 parts by weight of styrene-butadiene rubber, 0.25 parts of potassium hydroxide, 0.9 parts of p-nitrophenol, 8 parts of polycarbonate, 0.6 parts of copper oxide powder, disodium edetate 4 parts, 6 parts of glycidyl methacrylate, 0.151 parts of sodium nitrite and 3 parts of ferrous hydroxi...

Abstract

The invention provides a high-strength and low temperature-resistance pneumatic tire. The structure and the material of the tire are both optimized; as an elastic buffer layer is arranged, and components thereof are optimized, the pneumatic tire obtains the wear resistance, the impact resistance and the cold resistance far exceeding a traditional pneumatic tire; the tire still keeps higher stability and longer service life in the extreme environment; and the driving safety in the extreme environment is effectively improved.

Description

technical field [0001] The invention relates to a tire, in particular to a high-strength low-temperature resistant pneumatic tire. Background technique [0002] In order to obtain high mechanical strength and strong anti-wear performance, existing pneumatic tires usually modify and thicken the tread to protect the high-pressure pneumatic inner tube from being damaged by external influences, and realize The purpose of maintaining the working stability of the pneumatic inner tube and ensuring driving safety. However, after the strength and thickness of the tread reach a certain range, it cannot be improved again, otherwise the too hard and thick tread will reduce the ride comfort of the vehicle. In essence, even with the reinforced tread, the inner tube is still prone to wear and tear when working in a long-term, high-strength and extreme environment. An explosion occurred, seriously affecting driving safety. Contents of the invention [0003] In view of this, the present...
