What does the rubber softener used in the reclaimed rubber regeneration process affect
The main components of coal tar are phenols, alkyl aromatic hydrocarbons, naphthalene, bismuth, pyridine, and asphalt. It is the most commonly used softener in the production of early reclaimed rubber.Shanxi reclaimed rubber manufacturersIt is said that high-temperature coal tar is suitable for the production of ordinary reclaimed rubber, and solid coal tar can be used for the production of high-strength reclaimed rubber; however, the reclaimed rubber produced by coal tar as a softener is highly polluting and has a pungent smell, and has been banned by the state.
The main component of pine tar is resin acid, which is the product of the distillation of pine roots and trunks, which helps to increase the viscosity of the glue. Shanxi reclaimed rubber manufacturers said that in the regeneration process of vulcanized rubber and waste rubber products, the processing performance and physical and mechanical properties of recycled rubber can be improved; pine tar is mainly used to produce odorless recycled rubber.
The main components of rosin, which is processed by a special process, are resin acid and pinic acid glycosides, which can improve the viscosity and aging resistance of reclaimed rubber in the production process of reclaimed rubber.
The resin acids and fatty acids in tall oil each account for about 40%. They are by-products of the paper industry and are prone to stratification and precipitation of rosin during storage. When vulcanized rubber is regenerated as a softener, it needs to be heated, and the degree of pollution is low. It is mostly used for the production of environmentally friendly recycled rubber.
Shanxi reclaimed rubber manufacturers said that the rubber softener used in the regeneration process of recycled rubber will not only affect the quality of recycled rubber, but also affect the quality of rubber products containing recycled rubber. If inferior softeners and pollution softeners are used in the production process of recycled rubber, the produced rubber products are prone to quality problems, or low mechanical strength, or discoloration and migration, or do not meet relevant environmental protection and tasteless standards.
