    Rubber filling oil alias rubber matching oil。It is an oil compound with rubber and similar materials。It is used to reduce the ductility of rubber and the internal sliding friction between rubber molecular structures, improve its softness and aging resistance, and can yield high rubber。Commonly used are: ① p-xylene filling oil, the by-product extracted oil in the production process of petroleum lubricating oil organic solvent, the main components are p-xylene and cyclohexanol。② naphthenic filling oil, naphthenic base oil lubricating oil organic solvent production in the whole process of by-product extraction oil。③ Paraffin filling oil, such as white wax oil containing a lot of ethane, hydrorefined lubricating oil。

Rubber filling oil

    Rubber filling oil type and use
    The types of rubber filling oil are aliphatic oil, paraffin oil, naphthenic oil and so on。We often say that the production of white oil is actually filled with naphthane oil or paraffin oil, and China's SBS oil glue is mainly filled with naphthane oil。Note that naphthenic oil and paraffin oil can not be filled in addition, that is, after the paraffin oil can not be filled with naphthenic oil, the opposite is the same。Therefore, we need to pay attention to the case of filling oil, when selecting oil, we should choose a low cold filter point, open flash point high white oil, so that the oil flow performance is good, and the production and processing characteristics are good。
    The following is a practical introduction to paraffin oil, naphthenic oil and paraxylene oil and their uses。
    Paraffin oil (white oil)
    KP200#, KP300#, KP500#, KP6025#, KP6030#, paraffin-based rubber professional oil, with high paraffin hydrocarbon composition, low paraxylene composition, high opening flash point, small evaporation and other characteristics。Suitable for ethylene-propylene rubber, butyl rubber and other formulations。The molecular formula of paraffin base oil is dominated by straight chain hydrocarbon, the compatibility is poor, easy to exosmosis, and wax evolution at ultra-low temperature。
    Paraffin based oil can improve the fluidity, flexibility and light reliability of SEBS, and good coloring reliability, this is because the paraffin oil in the chain ethane molar quality is high, the paraxylene molar quality is very low, so this is why SEBS choose paraffin oil instead of paraxylene oil with good compatibility。Ethane oil with network structure is more flexible than naphthene oil and paraxylene oil, which is beneficial to improve the flexure of specimens。
    Naphthenic oil
    Naphthenic oil has naphthenic structure similar to that of paraxylene carbon and carbon bond structure similar to that of straight-chain carbon,Has stronger rubber compatibility than paraffin based oils,In addition, the ring structure is dominated by saturated hydrocarbons,Good anti-aging performance,And free from the pollution of the fragrant base oil,Have excellent physical and mental health coefficient,Generally suitable for all kinds of rubber。
    Note: One of the more critical items in the quality standard of oil-filled rubber for naphthenic oil is the paraxylene component, which harms the yellowing of the product. The lower the paraxylene component, the slower the yellowing rate of the product and the higher the product quality。
    P-xylene oil
    The key role of p-xylene oil is to improve the production and processing characteristics of rubber, assist the mixing and dispersing of the filler in the plastic pellet, reduce the viscosity of the plastic pellet and the energy consumption of the mixing rubber, and adjust the physical and physical properties of the vulcanized rubber。
Be generally applicable to...Rubber and rubber products from which rubber is derived;Widely used in actual operation oil, filling oil;The production and processing characteristics are better than chain ethane。Paraxylene oil has good compatibility with rubber, can improve tire grip and braking system, and is widely used in tire production and manufacturing, which is beneficial to filling and reducing rubber mixing temperature。适用...Rubber, styrene-butadiene rubber, butadiene rubber and compound formula, the compatibility between the two is good, and the compression ductility and extrusion production and processing of plastic pellets have excellent effects。
