Rubber oil Usage And Synthesis
Chemical Properties
1. Thickened aromatic hydrocarbons content There are many international methods to determine the content of thick aromatic hydrocarbons, such as IP346, high-pressure liquid chromatography (HPLC) and gas chromatography (GC). The results are different for different methods. The widely used method IP346 is the determination of substances dissolved in dimethyl sulfoxide (DMSO), which dissolves all thick and some monocyclic aromatic hydrocarbons as well as cycloalkanes, especially six-membered rings. IP346 has been linked to skin cancer in rat smear tests. According to European law, when the mass fraction of PAHs in oil is not less than 0.03, it must be labeled. For environmentally friendly, non-polluting high-grade rubber oil products, the use of IP346 to determine its thickened aromatic hydrocarbons content is very necessary.
2. Light stability Rubber product manufacturers usually pay more attention to the light stability of rubber oil. The double bond contained in rubber is sensitive to light, heat and oxygen, especially under ultraviolet light irradiation, yellowing, cross-linking, hardening and deterioration. Rubber oil light stability is medium and high-grade rubber in the processing and production process must be examined as an important indicator. China Petroleum Lubricants Research and Development Center Karamay Research Institute of rubber oil light stability of technical research, basically solved the problem of light stability of rubber oil, rubber oil color can be stabilized in the factory at a better level, and the development of a rapid detection of light stability of rubber oil test methods.
3. Thermal stability SR manufacturers pay more attention to the thermal stability of rubber oil. Elevated temperature will increase the rate of oxidation reaction, rubber in high-temperature processing due to molecular degradation of rubber properties decline, the thermal stability of the rubber oil has become an important factor to be considered in the rubber processing and production process. At present, China's petroleum production of rubber oil products, its thermal stability has been greatly improved, in 160 ℃ × 4h under the conditions of the rubber oil color change range is small, thermal stability is better than similar foreign products.
