Now the use of recycled rubber production cost of rubber products is the general trend, of which the largest variety, the largest amount of tire reclaimed rubber is made in the rubber products industry indelible contribution. The use of tire reclaimed rubber production of rubber products, usually need to add a formula called aromatic oil material which is why? Tire reclaimed rubber production of rubber products when adding aromatic oil What is the point?

The so-called aromatic oil is often said that aromatic hydrocarbons or aromatic hydrocarbons, a benzene ring structure of hydrocarbons, including benzene, toluene, xylene and ethylbenzene, rubber production and processing of the excipients. This is because aromatic oil with various types of rubber compatibility, and high temperature, low volatility, can significantly improve the processing performance of rubber and rubber products to improve weather resistance, oxidation resistance, friction, anti-aging properties, and promote A variety of complexing agents in the rubber evenly dispersed.

Tire reclaimed rubber is based on its own characteristics and the use of more aromatic compounds, the main component with a benzene ring structure, the purpose is to significantly improve the plasticity of rubber and filler dispersion, improve vulcanizate elongation, good resilience, wear Strong performance, improve the reclaimed rubber tire processing performance and performance.

Among them, the viscosity of aromatic oil will affect the performance of reclaimed rubber products. The viscosity not only affects the plasticity of rubber compound but also affects the physical and mechanical properties of vulcanizates. Using low viscosity aromatic oil can make vulcanizates have lower hardness and low temperature elasticity, But the loss of volatility is large. The use of high viscosity aromatic oil can improve the tensile strength, elongation at break and decrease the constant tensile stress of vulcanizates, but reduce the cold resistance and elasticity. Different viscosity aromatic oil different role, each have their own advantages.

Tire Recycled Rubber The addition of aromatic oil to rubber products improves the softening performance, dynamic modulus and viscoelastic properties of recycled rubber compounds to improve the aging properties of rubber compounds to a great extent to reduce heat generation and greatly improve the physical properties of rubber compounds And dynamic performance. However, it is important to note that aromatic hydrocarbon oils are commonly used only for ordinary tire reclaimed rubber products. The EU ROHS directive explicitly requires that rubber products not contain polycyclic aromatic hydrocarbons. Therefore, it is essential not to use aromatic oil in the export-oriented reclaimed rubber products. The use of recycled rubber tire manufacturer of rubber products should also pay attention to export, in the choice of tire reclaimed rubber must not buy the tire reclaimed rubber containing aromatic oil, otherwise it is "lost at the starting line."

Arene oil plays an important role in the production of reclaimed rubber products. Tire reclaimed rubber products manufacturers should decide whether to use aromatic oil according to their own needs and how much?
