The final mixes obtained in examples 1 to 3 and comparative examples 1 to 4 were examined for vulcanization characteristics, and the results of the examination are shown in Table 1. The instruments tested were commercially available MZ-4000D (Jiangsu Mingzhu tensile machine), GT-7080S2 (Dongguan high-speed rail instruments) and GT-M2000A (Dongguan high-speed rail instruments). The detection method is described in GB7036.2/2007. The properties of the rubber are tested according to national or industry standards.
TABLE 1
As can be seen from the data in table 1, the shore hardness in examples 1-3 was between 67 and 71 and the tear strength was between 117 and 122, wherein the shore hardness in comparative example 1 was increased by 3%, the tear strength was increased by 1.7%, the shore hardness in comparative example 2 was decreased by 4.5% and the tear strength was decreased by 2.6% as compared with the shore hardness in example 1. It can be seen that the ratio of the ethylene propylene diene monomer to the chlorinated butyl rubber is lower than the preferred range of the invention, the hardness and the tearing strength of the rubber are both increased, and the ratio of the ethylene propylene diene monomer to the chlorinated butyl rubber is higher than the preferred range of the invention, so that the hardness and the tearing strength of the rubber are both reduced, which is not beneficial to the improvement of the safety and the service life of the tire. Comparative example 3 has a 1.5% increase in Shore hardness compared to example 1, a 0.85% increase in tear strength, and comparative example 4 has a 7.5% decrease in Shore hardness compared to example 1, and a 3.4% decrease in tear strength. It can be seen that after the ratio of the AC foaming agent to the total number of the chlorinated butyl rubber and the ethylene propylene diene monomer is smaller than the preferred range of the invention, the hardness and the tearing strength of the rubber are both increased, and after the ratio of the AC foaming agent to the total number of the chlorinated butyl rubber and the ethylene propylene diene monomer is higher than the preferred range of the invention, the hardness and the tearing strength of the rubber are both reduced, which is not beneficial to the improvement of the safety and the service life of the tire.
The final mixes obtained in examples 1-3 and comparative examples 1-4 were tested for sound absorption properties using the GBT18696.2-2002 national standard test method. The test results are shown in Table 2. All performances are tested according to national or industry standards.
TABLE 2
As can be seen from the data in Table 2, the ratio of the ethylene propylene diene monomer to the chlorinated butyl rubber in comparative example 1 was lower than the preferred range of the present invention, the sound absorption coefficient was decreased at different frequencies, the ratio of the ethylene propylene diene monomer to the chlorinated butyl rubber in comparative example 2 was higher than the preferred range of the present invention, the sound absorption coefficient was increased, the ratio of the AC foaming agent to the total ethylene propylene diene monomer in comparative example 3 was smaller than the preferred range of the present invention, the sound absorption coefficient was decreased at different frequencies, and the ratio of the AC foaming agent to the total ethylene propylene diene monomer in comparative example 4 was higher than the preferred range of the present invention. Among them, the sound absorption coefficient of comparative example 3 was most reduced in magnitude and the silencing effect was worst.
Tires were prepared from the final mixtures obtained in examples 1 to 3 and comparative examples 1 to 4, and then performance tests were conducted on the tires using GBT18505-2013, and the test results are shown in Table 3.
TABLE 3 Table 3
As can be seen from the data in Table 3, the X-ray, dynamic balance and uniformity of the tire prepared from the silent rubber of the present invention all meet the factory inspection requirements of the tire, and the silent rubber material prepared by the present invention can reduce the noise of the tire without affecting the performance of the tire in other aspects and without interfering with the normal use of the tire.
The tires prepared in examples 1 to 3 and comparative examples 1 to 4 were subjected to noise reduction and silence performance test in an environment of expressway at a running speed of 100km/h using a Starry noise tester in an automobile. Wherein the original tire is a tire carried by an automobile, noise of the original tire was first tested, and then noise test was performed by replacing the original tire with the tires prepared in examples 1 to 3 and comparative examples 1 to 4, and the test results are shown in table 4.
TABLE 4 Table 4
As is clear from examples 1-3, the rubber materials treated according to the formulation of the present invention have significant noise reduction properties, and in comparative examples 1-2, the noise reduction properties of the tires are significantly reduced by 38% and 9.5% respectively, after the ratio of ethylene propylene diene monomer rubber to chlorinated butyl rubber is lower or higher than the preferred range of the present invention. The noise reduction performance of the tire was reduced by 54.8% after the ratio of the AC blowing agent to the total amount of chlorinated butyl rubber and ethylene propylene diene monomer rubber in comparative example 3 was lower than the preferred range in the present invention, and the noise reduction performance of the tire was increased by 23.8% after the ratio of the AC blowing agent to the total amount of chlorinated butyl rubber and ethylene propylene diene monomer rubber in comparative example 4 was higher than the preferred range in the present invention.
In summary, the addition of the ethylene propylene diene monomer and the AC foaming agent can improve the noise reduction performance of the rubber and achieve the effect of silence, but the ratio of the ethylene propylene diene monomer to the chlorinated butyl rubber and the ratio of the AC foaming agent to the total number of the chlorinated butyl rubber and the ethylene propylene diene monomer have influence on the hardness, the tearing strength and the noise reduction performance of the rubber, and the hardness and the supporting performance of the rubber material can be ensured and the effect of silence can be achieved by controlling the two ratios within the preferred range of the invention.
The present embodiment is illustrative of the present invention, but not limiting, and variations, modifications, additions or substitutions within the spirit and scope of the invention are possible, and any person skilled in the art who has read the present description can make modifications without creative contribution to the embodiment as required, but are protected by the patent laws within the scope of the claims of the present invention.
