Abstract
The invention provides a rubber composite for wear-resistant tire treads. The rubber composite is prepared from, by weight, 4-30 parts of natural rubber, 4-40 parts of butadiene rubber, 4-40 parts of styrene butadiene rubber, 35-75 parts of high-dispersion white carbon black, 3-10 parts of white mineral oil, 1.0-2.5 parts of indirect zinc oxide, 1.0-2.0 parts of stearic acid, 1.0-2.0 parts of rubber protecting wax, 1.0-2.8 parts of silane coupling agent, 1.0-2.0 parts of anti-aging agent, 1.0-2.0 parts of tackifying resin, 1.0-2.0 parts of dispersing agent, 1.0-2.8 parts of common sulphur, 0.5-2.0 parts of accelerant CZ, 1.0-2.0 parts of accelerant DPG and 0.1-1.0 part of accelerant DM, by proportioning according to the formula prior to mixing via an internal mixer. The rubber composite is mixed via the internal mixer by means of blending the natural rubber and the synthetic rubber as main materials which are matched with the high-dispersion white carbon black as a reinforcing agent and through unique anti-aging system design, and accordingly tire treads produced by the rubber composite are excellent in wear-resisting property, good in tear resistance and high in tensile strength, and service lives of tires for taxies, family cars and the like can be prolonged.
Description
Technical field
The present invention relates to doughnut, specifically a kind of wear-resistant tyre rubber composition for tire tread.
Background technology
Existing tyres for passenger cars ubiquity wear resisting property is poor, and tire tread is easily given the shortcoming of environment after wearing and tearing come off.How to improve the tire tread wear resisting property, the requirement that assurance tire mask meets environmental protection is an important topic of tyre industry.
Application number: 200710050386.7 applyings date: 2007-11-01 provides formula of high wear-resistant aviation tire tread glue, its tread rubber be take natural rubber as main material, with addition of the high structure high wear-resistant carbon black of novel process, the polymolecularity white carbon black, silane coupling agent, thermo-stabilizer is main subsidiary material, then, with addition of raw materials such as zinc oxide, stearic acid, p phenylenediamine type antioxidant, ketoamine class anti-aging agent, protection wax, insoluble sulfur, sulfenamide type acceleratorss, by mixer mixing, forms.
Due to this patent application, in design process, use natural rubber for material of main part, the natural rubber price is high, and if loss of properties on aging, in the middle and later periods of tire used process, there will be the abnormal tyre wear pattern, is unfavorable for the life-time service of tire; Moreover, because its price is higher, do not have to popularize use in an all-round way.
Summary of the invention
The present invention, in order to increase ageing resistance, extends the work-ing life of tire, a kind of wear-resistant tyre rubber composition for tire tread of special proposition.
Technical scheme of the present invention is for this reason, a kind of wear-resistant tyre rubber composition for tire tread, comprise natural rubber, it is characterized in that: be by weight, natural rubber is 4-30 part, cis-1,4-polybutadiene rubber is 4-40 part, styrene-butadiene rubber(SBR) is 4-40 part, high-dispersion white carbon black is 35-75 part, white mineral oil is 3-10 part, indirect process zinc oxide is 1.0-2.5 part, stearic acid is 1.0-2.0 part, Wax-for preventing rubber is 1.0-2.0 part, silane coupling agent is 1.0-2.8 part, anti-aging agent is 1.0-2.0 part, tackifying resin is 1.0-2.0 part, dispersion agent is 1.0-2.0 part, common sulphur 1.0-2.8 part, accelerant CZ is 0.5-2.0 part, vulkacit D PG is 1.0-2.0 part, altax is 0.1-1.0 part, after above-mentioned formulation ratio, use mixer mixing to form.
Beneficial effect:
The present invention adopts the rubber system of three kinds of rubber blendings, use cis-1,4-polybutadiene rubber and styrene-butadiene rubber(SBR) to replace the part natural rubber, because the synthetic rubber price is low, can greatly reduce material cost, and the characteristics of synthetic rubber ageing resistance excellence and wear resisting property number, combine the excellent properties of various rubber, carry the tyre surface formula wear resisting property and guarantee again the smooth and easy of complete processing.
Use high-dispersion white carbon black to substitute common black wood charcoal black, by adding of white carbon black, realized that tire tread becomes brown by common black, the production of tire has realized specializing, the combination synergistic effect that adds silane coupling agent by white carbon black, also guaranteed the wear resistance of tire, the aromatic hydrocarbon oil that simultaneously by white mineral oil, replaces tyre industry generally to use, stopped the absorption of the carcinogenic substances such as polycyclic aromatic hydrocarbons, guaranteed that the tire tread rubber combination meets environmental requirement.
Embodiment
Application example 1:
The present invention according to weight part basic recipe in a batch is: natural rubber is 30 parts, and cis-1,4-polybutadiene rubber is 35 parts, and styrene-butadiene rubber(SBR) is 35 parts, high-dispersion white carbon black is 63 parts, and white mineral oil is 10 parts, and indirect process zinc oxide is 2.5 parts, stearic acid is 1 part, and Wax-for preventing rubber is 2 parts, and silane coupling agent is 2.8 parts, anti-aging agent is 1-2 part, and tackifying resin is 2 parts, and dispersion agent is 1 part, 1.5 parts, common sulphur, accelerant CZ is 1 part, and vulkacit D PG is 2 parts, and altax is 0.1 part.
Application example 2:
By basic recipe, be: natural rubber is 35 parts, and cis-1,4-polybutadiene rubber is 30 parts, and styrene-butadiene rubber(SBR) is 35 parts, high-dispersion white carbon black is 63 parts, and white mineral oil is 10 parts, and indirect process zinc oxide is 2.5 parts, stearic acid is 1 part, and Wax-for preventing rubber is 2 parts, and silane coupling agent is 2.8 parts, anti-aging agent is 1-2 part, and tackifying resin is 2 parts, and dispersion agent is 1 part, 1.5 parts, common sulphur, accelerant CZ is 1 part, and vulkacit D PG is 2 parts, and altax is 0.1 part.
Above-mentioned formula is used mixer mixing to form.
The testing data contrast:
| Rubber is used | Application example 1 | Application example 2 |
| Tensile strength MPa | 26 | 24 |
| Tensile yield % | 450 | 480 |
| Shao Er hardness | 69 | 68 |
| Tear strength KN/m | 96 | 90 |
| Akron abrasion decrement M 3 | 0.230 | 0.250 |
By contrast, can reach a conclusion, at all the other Synergist S-421 95s under certain prerequisite, the tread mix of selecting example 1 to manufacture, its tensile strength, tear strength, Akron abrasion are all higher than example 2.
The tire that usage example 1 is produced, wear resisting property the best.
