Abstract
The invention relates to an automobile tire rubber composition comprising the following components in parts by weight: 100-120 parts of natural epoxy rubber, 20-40% of butadiene rubber, 0-10 parts of butadiene styrene rubber, 2-8 parts of zinc stearate, 30-35 parts of silicon dioxide, 1-2 parts of silane coupling agent, 0.5-1 part of carbon black, 1-3 parts of age resister, 0.5-8 parts of vulcanizing agent and 1-2 parts of vulcanization accelerator. The invention also provides a pneumatic tire produced from the rubber composition. The rubber composition provided by the invention can be used for inhibiting sulfurizing reduction and improving the mechanical strength and the wear resistance in a favorable balance way.
Description
Technical field
The invention belongs to doughnut, the pneumatic tyre that is specifically related to a kind of doughnut rubber combination and uses this rubber combination to produce.
Background technology
As the doughnut of automobile important component part, be the vitals that automobile bears gravity, transmitting tractive power, damping force, steering force and bears road surface reaction, its quality quality directly relates to personal safety as well as the property safety.In order to improve the earth-catching property of rubber composition for tyre, people use the rubber after the natural rubber modification, and wherein using more is epoxy natural rubber.Yet when using epoxy natural rubber to make doughnut, because epoxy natural rubber is subjected to thermal ageing easily, produce reversion, make tyre performance deterioration gradually in use.
Summary of the invention
In order to address the deficiencies of the prior art, the pneumatic tyre that the object of the present invention is to provide a kind of doughnut rubber combination and use this rubber combination to produce, described rubber combination can suppress reversion, has improved physical strength and wear resistance in well balanced mode simultaneously.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of doughnut rubber combination, component by following weight part is formed: epoxy natural rubber 100-120 part, divinyl rubber 20-40 part, styrene-butadiene rubber(SBR) 0-10 part, Zinic stearas 2-8 part, silicon-dioxide 30-35 part, silane coupling agent 1-2 part, carbon black 0.5-1 part, antiager 1-3 part, vulcanizing agent 0.5-8 part, vulcanization accelerator 1-2 part.
Preferably, described composition is made up of the component of following weight part: epoxy natural rubber 100-110 part, divinyl rubber 30-40 part, 5 parts in styrene-butadiene rubber(SBR), Zinic stearas 2-5 part, silicon-dioxide 30-35 part, silane coupling agent 1-2 part, carbon black 0.5-1 part, antiager 1-3 part, vulcanizing agent 0.5-5 part, vulcanization accelerator 1-2 part.
Described vulcanizing agent is sulphur, organo-peroxide or resin cure agent.
Described vulcanization accelerator is dithiocarbamate(s) or Thiourea vulcanization accelerator.
The present invention also provides a kind of pneumatic tyre that uses above-mentioned rubber combination to produce.
Wherein Zinic stearas can suppress the reversion of rubber combination, and further improves rubbery intensity and heat-resistant aging after the sulfuration; Silicon-dioxide and silane coupling agent can improve the rubber intensity after the sulfuration.
The invention has the beneficial effects as follows: rubber combination provided by the invention, can suppress reversion, improved physical strength and wear resistance in well balanced mode simultaneously.
