The base rubber compound for tires prepared according to the three formulations in example 2 was vulcanized at a positive vulcanization time of 150 ℃, and then performance tests were performed to examine various performance values of the tread rubber, and the test results are shown in fig. 1.
As can be seen from figure 1, the physical properties of the tire base rubber compound prepared by the invention meet the requirements of tires, the rolling resistance is low, and the tire base rubber compound is applied to tire production and effectively reduces the rolling resistance of the tires.
Example 4
Physical property test of finished products prepared by base rubber formula
The finished tire base rubber prepared according to the three formulations in example 2 was tested according to the testing methods specified by the national testing standards, such as: the durability of the finished product of the tire base rubber is detected according to GB/T4501-2016; the rolling resistance of the finished tire base rubber product is tested according to ISO 28580. The test results are shown in FIG. 2.
As can be seen from FIG. 2, the durability value of the finished tire base rubber prepared by the invention is 89, which is in the national standard of 47 h; the rolling resistance value is 4.5, which is lower than the requirement of European Union REACH regulation of 6.5. Therefore, the all-steel radial tire base rubber developed by the invention not only has lower tire rolling resistance, but also has higher wear resistance.
At present, in the mainstream tire formulation process research, in order to reduce the rolling resistance of the tire, the common scheme is to increase the use amount of the white carbon black, but the increase of the use amount of the white carbon black not only reduces the abrasion performance, but also reduces the processing performance, such as the expansion rate is increased and the size fluctuation is increased when the extrusion process is carried out.
In the invention, through experimental research, the low rolling resistance auxiliary agent is added in the formula of the base rubber of the all-steel radial tire, so that the rolling resistance of the tire can be obviously reduced, and the abrasion performance can be improved; it is known that in the formula design, the wear resistance can be well improved by increasing the carbon black dosage and using the carbon black with larger specific surface area, and the rolling resistance can be improved; however, in the present invention, by using a low rolling resistance aid in the formulation, the rolling resistance increase due to increased amounts or types of carbon black can be balanced.
Further studies have found that the principle of the low rolling resistance aid acting in the tire base stock formulation is as follows:
(1) the low rolling resistance auxiliary agent can react with surface chemical groups of the carbon black to help promote the dispersion of the carbon black, namely, the friction between the carbon black and the carbon black is reduced, the payne effect is reduced, the heat generation is reduced, and further the rolling resistance is reduced;
(2) the low rolling resistance auxiliary agent can also react with rubber molecules and is grafted on a rubber molecular chain, so that the free movement of rubber is reduced, the heat generation of the rubber is reduced, and the rolling resistance is reduced; after the rubber reacts with the rubber, the molecular weight of the rubber is increased, so that the wear resistance and the aging resistance are improved;
(3) the low rolling resistance auxiliary agent reacts with the rubber and the carbon black simultaneously, so that the movement of the carbon black is reduced, and the heat generation caused by the movement of the carbon black and the carbon black is further reduced, so that the rolling resistance reducing effect is further enhanced;
the design principle of the preparation process of the base rubber formula of the all-steel radial tire is as follows:
(1) the low rolling resistance auxiliary agent reacts with rubber and carbon black to really reduce rolling resistance, and in order to guarantee real reaction, firstly, the reaction environment needs to be 'pure', so the type of materials added in a section of mixing process is very critical; researches show that rolling resistance can be reduced only by mixing at least 10% of carbon black with a rolling resistance auxiliary agent in advance, and the filling amount of one-section mixed carbon black is increased as much as possible according to the actual carbon black dosage of a formula;
according to the above, 100% of rubber and 10% -100% of carbon black are required to be added in the first-stage process, and the addition of other materials except the two materials can have negative effects on the reaction, so that the materials added in the first-stage mixing process are rubber and carbon black, and the addition of other materials is not allowed;
(2) secondly, the low rolling resistance auxiliary agent is inactivated due to overhigh and overlow reaction temperature and reaction time; meanwhile, the reaction needs a certain time, and the reaction effect can be influenced by the duration of the mixing at high temperature; through research, the rubber discharging temperature is controlled at 160 ℃ with low rolling resistance after the low rolling resistance additive is added, the actually measured rubber discharging temperature is not allowed to exceed 160 ℃, the constant temperature keeping time cannot be less than 40S and cannot exceed 120S at the mixing temperature of 160 ℃ with 130 ℃, the rubber is degraded due to long-time reaction at high temperature, the low rolling resistance additive is consumed in advance during rubber degradation, the rolling resistance reducing effect is reduced, and the rolling resistance is increased due to heat generation caused by degradation.
In conclusion, the process design of the low rolling resistance additive is very important for the success of the formula, the low rolling resistance additive cannot play a role in reducing rolling resistance and can play a reverse role, and therefore, the design of the one-section mixing process using the low rolling resistance additive is the core of the whole process in the patent.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
