The processing of used tires into recycled rubber and the re-use of rubber products can be a milestone in the treatment of waste tires; the low price of tire reclaimed rubber products is not the source of raw materials, and is the main raw material for reducing the production cost of the rubber products industry. One. When rubber products manufacturers choose tire reclaimed rubber, strength, fineness, and Mooney are all important considerations, but some customers will ask: How many degrees of high temperature can tire reclaimed rubber resist? This is a difficult question for the salesperson.
What is the raw material for tire reclaimed rubber? Of course it is a waste tire! There are many reasons why car tires "change" into waste tires, including temperature. Generally, 80 degrees Celsius will accelerate tire aging, and when the temperature reaches 150 degrees Celsius, it will accelerate the tire cracking.
Secondly, we look at the rubber composition of tires: general automobile tires are made of natural rubber, styrene-butadiene rubber and butadiene rubber. The use temperature of natural rubber ranges from -60 °C to +80 °C. The temperature range of styrene-butadiene rubber is between -50 °C and +100 °C, and the temperature range of butadiene rubber is between -60 °C and +100 °C. The tire reclaimed rubber is processed from waste tires. The main components are natural rubber and butyl. Benzene glue, etc., as well as softeners, regenerating activators, etc. added during the production process, but the use temperature of the tire reclaimed rubber should not be too high.
Tests have shown that the tire reclaimed rubber has the best vulcanization temperature between 130-140 °C during use.
The raw materials and production processes of different kinds of rubber products are very different, such as the type of vulcanizing agent, the choice of reinforcing agent filler, the softener plasticizer, the design of anti-aging system, the mixing conditions in the production process, and the vulcanization conditions. The use temperature of rubber products, so even the use temperature of rubber products produced by the same kind of tire reclaimed rubber is very different. There is no clear value for the use temperature of rubber products with tire reclaimed rubber as the main raw material. Rubber product manufacturers can only meet their own needs by adjusting the formula and process conditions of tire reclaimed rubber products according to actual needs.
When tire rubber is used to produce rubber products, the tensile strength and tear strength of rubber products are directly related to the use temperature. If the temperature is too high, the tensile strength and tear strength of rubber products will decrease significantly. Filling a certain proportion of carbon black and white carbon can significantly improve this problem. By the end of last year, the number of motor vehicles in the country reached 301 million, including 217 million cars in the middle, which will inevitably lead to the continuous increase in the number of used tires. The increase in the number of used tires will promote the development of the tire reclaimed rubber industry to a certain extent. In the future rubber products industry, tire reclaimed rubber will play a greater role.
Finally, Xiaobian wants to ask: Are you going to use tire reclaimed rubber to produce rubber products with a high temperature resistance?
