Abstract
The invention relates to the technical field of rubber, in particular to an aging resistant and cracking resistant tread rubber composition of an engineering tyre. The aging resistant and cracking resistant tread rubber composition comprises the following ingredients by weight: 50-70 parts of butadiene styrene rubber, 1-3 parts of tear resistant resin, 20-30 parts of natural rubber, 50-70 parts of intermediate super abrasion furnace black, 10-20 parts of cis-butadiene rubber, 5-10 parts of aromatic oil, 3-6 parts of nanometer zinc oxide, 1-3 parts of stearic acid, 1-3 parts of p-phenylenediamine antioxidant, 1-3 parts of ketoamine antioxidant, 0.5-1.5 parts of paraffin wax, 1-2 parts of microcrystalline wax, 1.5-2.5 parts of sulfur, 1-2 parts of sulfenamide accelerator and 1-2 parts of an additional vulcanization stabilizer. According to the invention, a protection system is changed, the aging resistance of tread rubber is improved, a rubber system is adjusted to reduce the glass-transition temperature of the tread rubber, and the flexibility of the tread rubber at low temperature is improved.
Description
Technical field
The present invention relates to the rubber technology field, specifically a kind of ageing-resistant, anti-be full of cracks engineering tire tread rubber combination.
Background technology
As everyone knows; The handling characteristics of off-the-road tyre is to use environment abominable; Working conditions is harsh, and lifting capacity is big, and the environment for use temperature is between-30 ℃-40 ℃; Therefore in the problem of northern extremely frigid zones breach at the bottom of groove appears in regular meeting in winter, must improve the ageing-resistant and low temperature elasticity of tread rubber for this reason.
Summary of the invention
The object of the invention is exactly in order to overcome the deficiency of above-mentioned prior art; A kind of ageing-resistant, anti-be full of cracks engineering tire tread rubber combination is provided; Change the ageing-resistant performance that protection system improves tread rubber; Adjustment rubber system reduces the second-order transition temperature of tread rubber, improves the low temperature elasticity of tread rubber.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of ageing-resistant, anti-be full of cracks engineering tire tread rubber combination comprises in weight part:
Styrene-butadiene rubber(SBR) 50-70, anti tear resin 1-3,
Tree elastomer 20-30, intermediate super abrasion furnace black 50-70,
Cis-1,4-polybutadiene rubber 10-20, aromatic hydrocarbon oil 5-10,
Nano zine oxide 3-6, Triple Pressed Stearic Acid 1-3,
Ursol D anti-aging agent 1-3, ketoamine anti-aging agent 1-3,
Paraffin 0.5-1.5, Microcrystalline Wax 1-2,
Sulphur 1.5-2.5, sulphenamide promotor 1-2,
Postcure stablizer 1-2.
The invention has the beneficial effects as follows, change the ageing-resistant performance that protection system improves tread rubber, adjustment rubber system reduces the second-order transition temperature of tread rubber, improves the low temperature elasticity of tread rubber.
Embodiment
Below in conjunction with embodiment the present invention is done further description:
Tree elastomer of the present invention is a 20# standard glue; it is that TYC0500, Ursol D anti-aging agent are that N-(1; the 3-dimethylbutyl)-N '-diphenyl-para-phenylene diamine, ketoamine anti-aging agent are 2,2 that styrene-butadiene rubber(SBR) adopts styrene butadiene rubber sbr 1502, anti tear resin, and 4-trimethylammonium-dihyaroquinoline polymer, sulphenamide promotor are N tert butyl benzothiazole 2 sulfenamide; the postcure stablizer is a hexa-methylene-1, the two sulfuration of 6-sulfuric acid disodium salt.
The technical scheme that technical problem adopted that the present invention solves is: compare with common mining tyres tyre surface formula, and used a certain amount of cis-1,4-polybutadiene rubber, to improve the low temperature elasticity of tread rubber; Adopt paraffin and Microcrystalline Wax and usefulness simultaneously, ozone-resistant aging property when improving tread rubber low temperature.
