Abstract
The invention provides a tyre rubber composition suitable for wet slippery ground. The tyre rubber composition is prepared from the following raw materials in parts by weight: 50-70 parts of modified natural rubber, 20-30 parts of cis-butadiene rubber, 4-8 parts of an antioxidant, 8-16 parts of emery, 3-5 parts of zinc oxide, 10-24 parts of a wet-slip resistance additive and 0-6 parts of a plasticizer.
Description
Technical field
The present invention relates to a kind of rubber composition for tire, particularly relate to a kind of rubber composition for tyre being applicable to wet and slippery ground.
Background technology
In order to improve at the safe application performance of tire at ice and snow road, some tiremakers arrange safety stud on tire, but this method has very large shortcoming, it is easy to cause tread surface to damage, greatly shorten the work-ing life of tire, meanwhile, very large destruction can be caused to road when travelling on road surface with the tire that the method is produced, and cause environmental pollution.
In order to improve tire at wet and slippery ground earth-catching property, there is the Young's modulus thus the method for raising tractive force that reduce low temperature place.Such as, the method by using the content comprising the oil of increase to reduce rubber hardness.But there is the problem reducing tire operation stability in the method.
Patent JP2007-169431A discloses a kind of rubber combination using natural rubber and epoxy natural rubber to produce.But rubber combination still also has the space of improving fuel economy, wear resistance and wet and slippery ground use properties in well balanced mode.
Summary of the invention
Unresolved the problems referred to above, the invention provides a kind of rubber composition for tyre being applicable to wet and slippery ground, have excellent adherence properties, and environmental pollution is little simultaneously.
The following technical scheme of concrete employing:
Be applicable to the rubber composition for tyre on wet and slippery ground, raw material comprises by mass parts, modified natural rubber 50 ~ 70 parts, along divinyl rubber 20 ~ 30 parts, 4 ~ 8 parts, anti-aging agent, 8 ~ 16 parts, silicon carbide, 3 ~ 5 parts, zinc oxide, anti-slippery auxiliary agent 10 ~ 24 parts, 0 ~ 6 part, softening agent.
The rubber composition for tyre being applicable to wet and slippery ground provided by the invention, preferred raw material comprises by mass parts, modified natural rubber 70 parts, along divinyl rubber 28 parts, 5 parts, anti-aging agent, 12 parts, silicon carbide, 4 parts, zinc oxide, anti-slippery auxiliary agent 20 parts, 5 parts, softening agent.
The rubber composition for tyre being applicable to wet and slippery ground provided by the invention, the phosphorus content of described modified natural rubber is 120 ~ 200mg/Kg.
The rubber composition for tyre being applicable to wet and slippery ground provided by the invention, described anti-slippery auxiliary agent is the mixture of carbon black and white carbon black 3 ~ 5:1 in mass ratio.
The rubber composition for tyre being applicable to wet and slippery ground provided by the invention, described anti-aging agent is the mixture of antioxidant 4020 and anti-aging agent RD 1:1 in mass ratio.
The rubber composition for tyre being applicable to wet and slippery ground provided by the invention, described softening agent is common plasticizers in rubber for tire preparation, as aromatic hydrocarbons wet goods.
Compared to prior art, tire composition provided by the invention, is more suitable for the traveling on wet and slippery ground, especially improve ice and snow road by property and security.Tire tread material prepared by tire composition provided by the invention is soft, thus can produce larger frictional force, and the handling and security of vehicle on glare ice face is improved greatly.
