Embodiment 1

[0060] The ozone aging-resistant sidewall rubber for heavy trucks is composed of the following raw materials in proportions by weight:

[0061] Butadiene rubber 43 parts

[0062] Polyisoprene rubber 54 parts

[0063] Sulfur 2.1 parts

[0064] Carbon black N66020 parts

[0065] Aromatic oil 6.5 parts

[0066] 0.8 parts of stearic acid

[0067] Zinc oxide 2.9 parts

[0068] 1.9 parts of N-1,4-dimethylphenyl-p-phenylenediamino-5-triazine

[0069] 2.9 parts of N-1,3-dimethylbutyl-p-phenylenediamine.

[0070] The ozone aging-resistant sidewall rubber for heavy trucks described in Example 1 is used to reduce the rolling resistance of the tire by 35%, improve the wet skid resistance by 5%, increase the wear resistance by 11%, and reduce the fuel consumption by 8%. The side rubber is resistant to ozone aging and prolongs the service life of the tire by 9.5 years.

Embodiment 2

[0072] The ozone aging-resistant sidewall rubber for heavy trucks is composed of the following raw materials in proportions by weight:

[0073] Butadiene rubber 46 parts

[0074] Polyisoprene rubber 56 parts

[0075] Sulfur 2.0 parts

[0076] Carbon black N66021 parts

[0077] Aromatic oil 7.0 parts

[0078] Stearic acid 1.0 parts

[0079] Zinc oxide 3.0 parts

[0080] 2.1 parts of N-1,4-dimethylphenyl-p-phenylenediamino-5-triazine

[0081] 3.1 parts of N-1,3-dimethylbutyl-p-phenylenediamine.

[0082] The ozone aging-resistant sidewall rubber for heavy trucks described in Example 2 is used to reduce the rolling resistance of the tire by 36%, improve the wet skid resistance by 4.6%, increase the wear resistance by 12.3%, and reduce the fuel consumption by 9.3%. The side rubber is resistant to ozone aging, prolonging the service life of the tire by 12.5 years.

Embodiment 3

[0084]The ozone aging-resistant sidewall rubber for heavy trucks is composed of the following raw materials in proportions by weight:

[0085] Butadiene rubber 45 parts

[0086] Polyisoprene rubber 57.5 parts

[0087] Sulfur 1.9 parts

[0088] Carbon black N66019 parts

[0089] Aromatic oil 7.2 parts

[0090] 0.9 parts of stearic acid

[0091] Zinc oxide 3.1 parts

[0092] 1.8 parts of N-1,4-dimethylphenyl-p-phenylenediamino-5-triazine

[0093] 2.8 parts of N-1,3-dimethylbutyl-p-phenylenediamine.

[0094] The ozone aging-resistant sidewall rubber for heavy trucks described in Example 3 is used, so that the rolling resistance of the tire is reduced by 34%, the wet skid resistance is improved by 5.1%, the wear resistance is increased by 13.3%, and the fuel consumption is reduced by 8.3%. The side rubber is resistant to ozone aging and prolongs the service life of the tire for 10 years.

Abstract

The invention belongs to the technical field of rubber production, and specifically relates to an ozone and aging resistant sidewall rubber for heavy trucks. The ozone and aging resistant sidewall rubber for heavy trucks is composed of the following raw materials: butadiene rubber, polyisoprene rubber, sulfur, carbon black N660, aromatic hydrocarbon oil, stearic acid, zinc oxide, N-1,4-dimethylphenyl-p-phenylamino-5-triazine and N-1,3-dimethylethyl-p-phenylenediamine. The sidewall rubber has excellent properties of ozone resistance, anti-aging property, and cracking resistance, does not contain any wax, and thus avoids the problems of rubber adhesiveness decrease and over blooming on the surface.

Description

technical field [0001] The invention belongs to the technical field of rubber production, and in particular relates to an ozone aging-resistant sidewall rubber for heavy trucks. Background technique [0002] A tire is a ring-shaped elastic body assembled on a rim or a wheel axle, which is a connecting body between a vehicle and a road, and is used for the running and sliding of a vehicle or an aircraft. A set of tires with an inner tube usually consists of 3 pieces: the outer tire, the inner tube, and the pad. Among them, the outer tire is the outer shell of the tire used to withstand various forces; the inner tube is used to maintain the internal pressure of the tire, and has a circular elastic body with a tire valve; the pad belt is used to protect the inner tire from the wear of the rim. ring belt. The tread is the driving surface, which is the crown part of the tire, that is, the rubber layer of the tire on the belt layer or the buffer layer. It has a certain cross-sec...
