Background
On a cement mill, a grinding roller is arranged at one end of a grinding material bin, and a grinding head of the grinding roller is positioned in the grinding material bin for grinding materials. A rubber sealing ring is arranged between the grinding roller shaft and the grinding material bin, so that dust in the grinding material bin can be prevented from escaping, and the movement of the grinding roller is not influenced. A material for producing cement throws into the mill feed bin after heating in, grinds into the likepowder back through the bistrique extrusion, is gone out by the suction of negative pressure adsorption equipment with the cement powder in mill feed bin, consequently, the operational environment in the mill feed bin is in the abominable state of negative pressure, high temperature, dust are densely covered, leads to rubber seal extremely easily to warp, wearing and tearing, has to frequently shut down the machine and changes, has increased manufacturing cost, has reduced production efficiency.
In order to solve the problem of serious deformation and abrasion of the rubber sealing ring, the industry personnel continuously research and discuss, on one hand, the structure of the sealing ring is improved, on the other hand, the material is improved, but the results are not ideal, especially on the material aspect, most of the sealing rings can only be made of common rubber materials, and the deformation resistance and the abrasion resistance are difficult to be obviously improved.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provide a synthetic rubber material which has good fatigue resistance and wear resistance and high temperature resistance.
The technical scheme adopted by the invention is as follows:
a wear-resistant anti-fatigue synthetic rubber material comprises the following components in percentage by mass: 35-45.5% of natural rubber, 19-30% of styrene-butadiene rubber, 2-4.5% of zinc oxide, 1-4% of stearic acid, 2-3% of paraffin, 1-2% of sulfur, 0.8-1.2% of accelerator CZ, 26-33% of carbon black and 2.2-4.3% of anti-aging agent.
Further, the anti-aging agent comprises 1-2% by mass of rubber anti-aging agent 4010NA, 1-2% by mass of anti-aging agent TMQ and 0.1-0.3% by mass of anti-aging agent 4020.
Compared with the material of the rubber sealing ring on the existing cement mill, the synthetic rubber material of the invention has obviously improved fatigue resistance and wear resistance, and has better high temperature resistance. The sand blasting test is carried out at the temperature of 70-100 ℃, and basically no abrasion is caused in 72 hours. Folding tests are carried out, the folding is not damaged after ten thousand times, and the anti-fatigue performance is very good. The rubber sealing ring material on the existing cement mill is subjected to a sand blasting test under the same condition as the material of the invention, the material is abraded by half the thickness within 24 hours, and the material is damaged after 3000 times of folding tests.
Through practical production tests, the cement mill sealing ring made of the synthetic rubber material can be well suitable for severe conditions of cement production, can resist a high-temperature environment during cement grinding, still has good wear resistance and fatigue resistance at high temperature, and can be used for 6-8 months. The rubber sealing ring of the cement mill in the prior art is seriously deformed and worn after 20 days to 2 months and must be replaced. The machine is stopped for 3-5 days during each replacement, and the normal production is seriously influenced.
