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 a kind of underground mining is with scraper tire tread rubber combination.
Background technology
As everyone knows, underground mining is that the place environment is abominable, working conditions is harsh, lifting capacity is big with the handling characteristics of racing slick.Therefore require the racing slick tread rubber to have anti-cutting, antifatigue, wear-resisting, low-heat-generation, characteristics that hardness is high, the racing slick tread thickness is thicker simultaneously, under long-term continuous operation, problems such as racing slick tyre surface delamination often occur 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; Provide a kind of underground mining with scraper tire tread rubber combination; Adopt compound tyre surface, the upper strata tyre surface adopts thorn resistance ability, initial be full of cracks performance, thermotolerance, styrene-butadiene rubber(SBR) that ageing-resistant performance is good, and lower floor's glue adopts also usefulness of tree elastomer and styrene-butadiene rubber(SBR); It is low to give birth to heat, and bond properties is good.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of underground mining comprises upper strata rubber combination and lower floor's rubber combination with scraper tire tread rubber combination,
The upper strata rubber combination is a benchmark with the styrene-butadiene rubber(SBR) of 100 weight parts, also comprises in weight part:
Nano zine oxide 3-5,
Triple Pressed 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,
Tree elastomer 60-80,
Nano zine oxide 5-10,
Triple Pressed Stearic Acid 1-3,

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, the upper strata tyre surface adopts thorn resistance ability, initial be full of cracks performance, thermotolerance, styrene-butadiene rubber(SBR) that ageing-resistant performance is good, and lower floor's glue adopts tree elastomer and styrene-butadiene rubber(SBR) and usefulness, and life is hot low, and bond properties is good.
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 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, Ursol D anti-aging agent, 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.Intermediate super abrasion furnace black is the N220 carbon black.Scorch retarder is N-cyclohexyl-sulfo-phthalic imidine.
Tree elastomer described in the prescription has the characteristics of strength and extension property height, good combination property; Butylbenzene SBR1502 rubber has anti-puncture, characteristics that ageing-resistant performance is good; The N220 carbon black has the characteristics wear-resisting, that tear strength is high, through scientific matching, develops wear-resisting, the anti-puncture in upper strata, lower floor's low-heat-generation, the tire tread glue that bond properties is good.
Embodiment: (each material content unit is in this table: weight part)
Embodiment physical property such as following table:
The living heat of glue is higher than former compsn from upper strata, last table visible adjustment back; But abrasion are better than former compsn; The living heat of lower floor's glue is lower than former compsn; But abrasion are higher than former compsn, and hierarchial design can be taken into account down the low-heat-generation and the upper strata glue excellent abrasive ability of layer sizing, thereby obtains the excellent comprehensive performance.
The formulated rubber material performance is through testing its performance range such as following table:
The invention has the advantages that:, make underground mining take into account the requirement that wear-resisting, anti-puncture, low-heat-generation etc. give shield mutually, the work-ing life of having improved tire greatly with the tread rubber of racing slick through adopting compound tyre surface.
Adopt compound tyre surface and the common single tyre surface of this invention to produce the 10.00-20-16PR cover tire respectively and carried out indoor machine test and actual road(wear)test, the finished tire testing data is following:
| 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 |
