The situation that China's high-end synthetic lubricants have been severely restricted by people is expected to change. The reporter learned from Xi'an Aim Polymer Material Co., Ltd. yesterday that a new generation of fully synthetic lubricant (base oil) independently developed by the company not only has a viscosity index higher than the current international average, but also has a low pour point and oxidation resistance. , corrosion resistance, environmental protection and other advantages. At present, this product has entered the pilot stage of industrialization. Aim company is debugging the pilot test equipment. It will refine and improve the product application field and product variety to prepare for industrialization. Lubricants are widely used in industry. China's annual demand for lubricants is about 9.5 million tons, and most of them are traditional mineral oils produced by petroleum refining. Due to the mixture of traditional lubricating oils, the molecular size is different, the material composition is different, and the lubrication effect is poor. Synthetic lubricants as a new high-end product, the core technology has been monopolized by the developed countries such as the United Kingdom and the United States. At present, synthetic lubricants in Europe and America account for more than 50% of the market, while China only 15%. Base oils are still heavily dependent on imports, and the localization rate is less than 3%. According to the company's technical director Wang Jing, after more than one year of trial and research, the new generation of synthetic lubricants (base oil) technology has been successfully applied. This lubricating oil is made of olefins with a viscosity index of 140 to 180 and a maximum of 210. This is not only higher than the 90 to 100 percent of fossil lubricants, but it also meets or exceeds the American Petroleum Institute (API) and the American Society of Automotive Engineers (SAE) lubricant international standards. At the same time, the lubricant has superior low temperature performance and a pour point of -60°C to -50°C, ensuring fluidity at low temperatures, thus protecting the engine from normal operation at extremely low temperatures. By gel permeation chromatography and nuclear magnetic resonance testing of Northwestern University and Shaanxi Provincial Petroleum Products Quality Supervision and Inspection Center, the product has a homogeneous base oil molecule, which can greatly reduce the friction coefficient. “These are just the test results of the base oil. If the additives are used to reconcile, the viscosity index and other indicators will be higher. They can be applied to aviation, automobiles, military, machinery, precision instruments and other fields.†Cao Jiangyu told reporters, such as nano materials The technology is applied in this lubricant product. Nanomaterials act on the surface of the machine parts with the lubricant, and the sliding friction becomes rolling friction, and the friction coefficient will be greatly reduced. At the same time, the nano-particles penetrate into the dents and pores of the metal surface to form a protective film, which has extremely strong mechanical anti-wear properties, and the physical properties of the nano-materials can also be effectively exerted. He said that foreign synthetic lubricants also use polymerization technology, but the company's process is even more simplified. At present, the company has obtained 5 national invention patents for preliminary examination.
