Small particles have an impact, and the softening effect of lauric acid and oleic acid is also very good. However, excessive unsaturation of oleic acid will interfere with the rubber processing process, and oleic acid also tends to increase rubber aging. The acid value of lauric acid is very high, which will greatly delay the vulcanization of rubber. The factory needs to change the formula and adjust the process parameters. Due to formula restrictions and certain parameter considerations, companies basically only use stearic acid.
In practical applications, various application manufacturers and research institutions do not have a unified view on what specifications of stearic acid should be used: Regarding the content: some think that a higher content should be used, while others think that an ordinary grade can be used. Regarding iodine value: the lower the iodine value, the better. Regarding the acid value: The acid value of stearic acid should be controlled within a corresponding reasonable range, and this amplitude value should be as small as possible. It is appropriate to control the acid value content at -.
Although domestic enterprises have not done enough research on the effects of stearic acid, the quality requirements for stearic acid have become higher and higher, especially with the increasing production of radial tires. In order to adapt to various road conditions, the requirements for tires Quality requirements are becoming more and more stringent, and the quality requirements for various raw materials (including stearic acid) are also constantly improving. The same goes for regular bias tires. With the continuous improvement of production technology of various enterprises, the quality management system of enterprises is becoming more and more standardized, and the quality requirements for stearic acid are becoming more and more detailed. In this case, standardized, stable, large-volume, and high-quality products should be used instead of the opposite. When the various functions of stearic acid are not fully understood, using high-quality stearic acid to produce high-quality and high-end tires, and using better stearic acid to make ordinary tires is not only a guarantee for user safety, but also an enterprise On the premise of ensuring quality, enterprises will feel more at ease in production and sales.
