Description
Technical Field
The invention belongs to the field of tires, and particularly relates to a rubber composition for protecting rubber at the end part of a belt speed layer of a tire, a low rolling resistance tire tread and the tire.
Background
The disclosure of this background section is only intended to increase the understanding of the general background of the invention and is not necessarily to be construed as an admission or any form of suggestion that this information forms the prior art already known to those of ordinary skill in the art.
The belt speed layer is a key component of the radial tire, bears about 70% of internal stress, and realizes smooth transition at the same time, and avoids the phenomenon of void between the belt speed layer and the tire shoulder, so that the belt speed layer structure and the rubber formula are important points of tire design. In general, the belt speed layer compounds are required to have high strength, fatigue resistance, heat resistance and good adhesion properties. However, in the long-time practical use process of the tire, the belt speed layer end part often causes the phenomena of degumming and void removal of the shoulder part due to the defects of shearing resistance, fatigue resistance and heat resistance, and finally affects the service life of the tire.
Therefore, there is a need for a rubber composition for belt speed layer end protection, which has excellent fatigue resistance, shear resistance and heat resistance, and also has the requirements of high adhesion and high strength, and the prepared tire has excellent durability.
On the other hand, the load of the heavy-duty tire is higher and the condition is more complex in the use process. Under the condition of long-time running, the temperature of the crown part can be continuously increased, heat accumulation of the rubber material and thermal oxidation aging are accelerated, and cracks caused by fatigue of the rubber material can also directly cause disease symptoms such as shoulder void, crown void and the like. In addition, excessive heat generation of the tire means that the mechanical energy loss of the tire is large during running, and the fuel consumption of the vehicle is increased. At present, the technical means adopted for reducing the heat generation of the tire can bring adverse effects on the tire such as poor cutting resistance, puncture resistance and the like, which seriously affect the usability and safety of the tire. Therefore, the method has very far-reaching significance in reducing heat accumulation and improving the durability and the safety of the tire under the condition of ensuring the high mechanical strength, the high cutting resistance and the high puncture resistance of the tire.
At present, the common heat conducting filler can improve the dynamic heat generation of the sizing material on one hand and sacrifice the mechanical property of the sizing material on the other hand. However, the mechanical properties of the rubber material are negatively affected by the common low-heat-generation materials. Therefore, a novel low-heat-generation filler and a novel heat-conducting filler are required to perform a synergistic effect on the rubber composite material matrix, so that the heat-conducting property of the composite material is effectively improved, the dynamic heat generation is ensured to be lower, and the mechanical property of the rubber material is not lost, thereby further improving the durability and the use safety of the tire product.
In addition, it is known to reduce the rolling resistance of a tire as a technical means for reducing the fuel consumption of a tire. At present, the method adopted from the formula mainly comprises the following steps: (1) raw rubber system: natural rubber and butadiene rubber are beneficial to reducing rolling resistance, but have poor wet skid resistance and handling performance; styrene-butadiene rubber can improve the wet skid resistance and handling properties of the tire, but increases rolling resistance. The general rubber is difficult to simultaneously meet all the required performances, and the solution polymerized styrene-butadiene rubber can balance three performances, but has less industrial application in the heavy duty tires. (2) Filling system: white carbon black is adopted or the dosage of carbon black is reduced. However, when white carbon black is adopted to reduce the rolling resistance of the tire, the defects of poor processability of rubber materials, multi-stage mixing, high mixing energy consumption, strict control of mixing time and temperature and the like are faced. (3) Other auxiliary agents: such as short fibers, which, although reducing the heat build up of the compound, increase the viscosity of the compound, with poor dispersibility and poor processability of the compound. Therefore, there is a need for a high performance tread rubber composition that has low heat build up, high mechanical properties, high cut resistance, and a tire made therefrom that has excellent puncture resistance, fast drop resistance, and durability, and is more environmentally friendly at lower carbon.
