Rubber oil can be divided in rubber filling oil, rubber processing oil, and rubber softener according to the object of use. The main role of rubber processing oil is to improve the reclaimed rubber operation process, and most of them consist of complex hydrocarbon compounds with a molecular weight of 300-600. Common aromatic oils, naphthenic oils, and paraffin oils, different types of rubber operations have different effects on the reclaimed rubber processing technology, and there are differences in the types of processing oils used in the production of different reclaimed rubber products.
1. Effect of rubber processing oil on processing performance of reclaimed rubber
Adding rubber oil in the mixing process will increase the plasticity of reclaimed rubber, reduce the hardness of reclaimed rubber compound, and improve the mixing process of reclaimed rubber products: the lower the viscosity, the higher the aromatic content, the faster the absorption, and can reduce the heat generated by reclaimed rubber. , Reduce the energy consumption in the production process; Adding rubber oil to the reclaimed rubber compound can soften the rubber material, help the surface of the reclaimed rubber semi-finished product to be smooth and smooth, and improve the extrusion performance of the reclaimed rubber products; rubber oil to a certain extent It can also slow down the speed of reclaimed rubber vulcanization. This is because the increase in oil will cause the concentration of vulcanizing agents and accelerators in the reclaimed rubber formula to decrease in the reclaimed rubber, and the vulcanization speed will slow down. Therefore, the rubber product manufacturers are considering reclaimed rubber processing technology. At the same time, the effect of the operating oil on the vulcanization speed of reclaimed rubber products must also be affected.
2. What kind of rubber oil is best for different kinds of reclaimed rubber products?
The reclaimed rubber products mainly include latex reclaimed rubber, tire reclaimed rubber, butyl reclaimed rubber, nitrile reclaimed rubber, and EPDM reclaimed rubber. They can replace the corresponding raw rubber to produce rubber products and significantly reduce the cost of raw materials, among which: Recycled rubber products can choose naphthenic oil or paraffin oil with low viscosity; EPDM reclaimed rubber products do not use aromatic oil, usually paraffin oil or naphthenic oil; nitrile reclaimed rubber is the best raw material for oil-resistant rubber products. Generally, no operating oil is used, and synthetic plasticizers are often used.
3. Different effects of different types of rubber processing oil on the properties of reclaimed rubber products
The compatibility of aromatic oil and rubber is good, can significantly improve the processing performance of reclaimed rubber products, but the pollution is greater; naphthenic oil pollution is less, can be used to produce a variety of light colored, colored rubber products; paraffin oil pollution is minimal, However, the compatibility with reclaimed rubber is poor, and it is mostly used in the production of light-colored reclaimed rubber products and odorless reclaimed rubber products.
The rubber processing oil can significantly improve the reclaimed rubber processing technology and reduce the energy consumption during the processing of rubber products. It is an indispensable compounding agent in the production of reclaimed rubber products.
