The tread rubber composition comprises an upper layer rubber composition and a lower layer rubber composition, wherein the upper layer rubber composition also comprises the following components in parts by weight by taking 100 parts by weight of butadiene styrene rubber as a reference: 3-5 parts of nano zinc oxide, 1-3 parts of stearic acid, 1-3 parts of protective wax, 1-3 parts of ketoamine anti-ageing agent, 1-3 parts of p-phenylenediamine anti-ageing agent, 60-70 parts of medium-super abrasion resistant carbon black, 8-12 parts of aromatic oil, 2-4 parts of post-vulcanization stabilizer, 1-2 parts of sulphur, 0.5-1.5 parts of sulphonamide promoter and 0-0.5 part of N-(Cyclohexylthio)phtalimide; and the lower layer rubber composition comprises the following components in parts by weight: 20-40 parts of butadiene styrene rubber, 60-80 parts of natural rubber, 5-10 parts of nano zinc oxide, 1-3 parts of stearic acid, 0.5-1.5 parts of protecting wax, 1-3 parts of ketoamine anti-ageing agent, 1-3 parts of p-phenylenediamine anti-ageing agent, 2-4 parts of post vulcanization stabilizer, 55-65 parts of medium-super abrasion resistant carbon black, 5-15 parts of aromatic oil, 1-2 parts of sulphur, 1-2 parts of sulphonamide promoter and 0-0.5 part of N-(Cyclohexylthio)phtalimide.
Description
Technical field
The present invention relates to a kind of rubber technology field, specifically scraper tire tread rubber combination for a kind of underground mining.
Background technology
As everyone knows, underground mining is that place environment is severe, working conditions is harsh, lifting capacity is large by the handling characteristics of racing slick.Therefore require racing slick tread rubber to have resistance to cutting, antifatigue, wear-resisting, low-heat-generation, feature that hardness is high, racing slick tread thickness is thicker simultaneously, under long-term continuous operation, often occurs the problems such as racing slick tyre surface delamination for this reason.
Summary of the invention
Object of the present invention is exactly in order to overcome above-mentioned the deficiencies in the prior art, scraper tire tread rubber combination for a kind of underground mining is provided, adopt compound tyre surface, upper strata tyre surface adopts thorn resistance energy, initial be full of cracks performance, thermotolerance, styrene-butadiene rubber(SBR) that ageing-resistant performance is good, lower floor's glue adopts natural rubber and styrene-butadiene rubber(SBR) and uses, heat-dissipating is low, and bond properties is good.
The technical scheme that the present invention solves the problems of the technologies described above employing is: scraper tire tread rubber combination for a kind of underground mining, comprise upper strata rubber combination and lower floor's rubber combination,
Upper strata rubber combination, the styrene-butadiene rubber(SBR) of 100 weight parts of take is benchmark, in weight part, also comprises:
Nano zine oxide 3-5,
Stearic acid 1-3,
Protection wax 1-3,
Ketoamine anti-aging agent 1-3,
Ursol D anti-aging agent 1-3,
Intermediate super abrasion furnace black 60-70,
Aromatic hydrocarbon oil 8-12,
Postcure stablizer 2-4,
Sulphur 1-2,
Sulphenamide promotor 0.5-1.5,
N-cyclohexyl-sulfo-phthalic imidine 0-0.5;
Lower floor's rubber combination, comprises in weight part:
Styrene-butadiene rubber(SBR) 20-40,
Natural rubber 60-80,
Nano zine oxide 5-10,
Stearic acid 1-3,
Protection wax 0.5-1.5,
Ketoamine anti-aging agent 1-3,
Ursol D anti-aging agent 1-3,
Postcure stablizer 2-4,
Intermediate super abrasion furnace black 55-65,
Aromatic hydrocarbon oil 5-15,
Sulphur 1-2,
Sulphenamide promotor 1-2,
N-cyclohexyl-sulfo-phthalic imidine 0-0.5.
The invention has the beneficial effects as follows, adopt compound tyre surface, upper strata tyre surface adopts thorn resistance energy, initial be full of cracks performance, thermotolerance, styrene-butadiene rubber(SBR) that ageing-resistant performance is good, and lower floor's glue adopts natural rubber and styrene-butadiene rubber(SBR) use, and heat-dissipating is low, and bond properties is good.
Embodiment
Below in conjunction with embodiment, the invention will be further described:
Natural rubber of the present invention is 20# standard rubber; it is N-(1 that styrene-butadiene rubber(SBR) adopts styrene butadiene rubber sbr 1502, Ursol D anti-aging agent; 3-dimethylbutyl)-N '-diphenyl-para-phenylene diamine, ketoamine anti-aging agent be 2; 2; 4-trimethylammonium-dihyaroquinoline polymer, sulphenamide promotor are N tert butyl benzothiazole 2 sulfenamide; postcure stablizer is hexa-methylene-1, the two sulfuration of 6-sulfuric acid disodium salt.Intermediate super abrasion furnace black is N220 carbon black.Scorch retarder is N-cyclohexyl-sulfo-phthalic imidine.
Natural rubber described in formula has that strength and extension property is high, the feature of good combination property; Butylbenzene SBR1502 rubber has resistance to puncture, feature that ageing-resistant performance is good; N220 carbon black has the feature wear-resisting, tear strength is high, by scientific matching, develops wear-resisting, the resistance to puncture in upper strata, lower floor's low-heat-generation, the tire tread glue that bond properties is good.
Embodiment: (Ben Biaozhongge material content unit is: weight part)
Embodiment physical property is as following table:
After adjusting as seen from upper table, the heat-dissipating of upper strata glue is higher than former composition, but abrasion are better than former composition, the heat-dissipating of lower floor's glue is lower than former composition, but abrasion are higher than former composition, hierarchial design can be taken into account the low-heat-generation of lower layer sizing and the wear resisting property of upper strata glue excellence, thereby obtains excellent over-all properties.
After tested, its performance range is as following table for formulated rubber material performance:
The invention has the advantages that: by adopting compound tyre surface, make underground mining take into account the requirement that wear-resisting, resistance to puncture, low-heat-generation etc. give mutually shield, the work-ing life of greatly having improved tire with the tread rubber of racing slick.
Adopt the compound tyre surface of this invention and common single tyre surface to produce respectively 10.00-20-16PR cover tire and carried out indoor machine test and actual road(wear)test, finished tire testing data is as follows:
Shop experiment | Compound tyre surface | Single tyre surface |
Endurance quality/h | 88 | 56 |
Actual road(wear)test (mean life) | 1 year six months | Seven months |
