The sustainable development strategy of the global economy places more emphasis on the harmonious relationship between "people and nature", which in turn determines that the main direction of future technology research and development in the automotive industry is inseparable from the theme of "safety, environmental protection, and energy conservation." As a supporting material for automobiles, automotive greases can play an important role in the safety, environmental protection and energy saving of automobiles. We must grasp this general direction when developing new automotive grease products. And Jia Dan Kermo also carried out major technical research and development in the automotive grease.

    When it comes to safety, the most important thing about grease is reliability. As a component of a mechanical part, it must be reliable in itself. That is to say, it does not deteriorate in the natural environment, it is not easy to deteriorate under the action of temperature, load, medium and machinery or current in the working environment, and it should maintain the performance it should have within the time limit specified in the design of the part, and leave room for it. Just like the safety factor of other mechanical parts. In order to achieve this, at the beginning of new product development, it is necessary to fully analyze and use all the information that can be collected, including text information and physical information, combined with China's resource conditions, carefully design the development route according to the use requirements, and use the required performance tests. Means to screen and evaluate samples. It is worth emphasizing that in addition to physical and chemical performance testing, special attention should be paid to simulated mechanical tests, component tests, bench tests, and road driving tests. The friction and wear lubrication mechanism of any automobile component is extremely complicated, especially for grease lubrication which is mainly in the boundary lubrication condition. These tests are gradually approaching actual use, the more difficult and the higher the cost. Generally, do as much physical and chemical performance testing and simulated mechanical testing as possible, and accumulate the relationship between the two and the bench test before finally performing the road driving test.

    As far as environmental protection is concerned, the grease itself should try to use components that do not pollute the environment to avoid pollution to soil and water sources after leakage or discard. The minimum requirements are (or low toxicity) and biodegradable. For example, lead compounds used to increase the extreme pressure and water resistance of greases are potentially toxic to nerves and reproduction, and lead-free components have not been used in lubricating greases since the 1970s. The "green" extreme pressure element that replaces lead is bismuth, which does not cause ecological problems. The lead-free additive is a lead-free additive of the parathion type. This lead-free additive is also an alternative to chlorinated paraffin, as chlorinated paraffin with a chain length of C12 was found to be a carcinogen in biological tests. From a biodegradable point of view, it is necessary to use biodegradable components of the grease components, especially vegetable oils, ester oils, some polyethers, and polyalphaolefins. Environmental protection is also concerned with more efficient use of raw materials, energy and water, including the basic use of recycled and reused materials; production processes, sales and products are safer; products minimize emissions and waste, and the ultimate goal is zero emissions, etc. . This involves the entire process of product production, packaging, transportation, use and disposal.

    Reduce friction to save power consumption and reduce wear to save material consumption are energy saving. A considerable part of the mechanical work of the automobile engine is lost in the internal friction and the friction of the transmission system, which include grease-lubricated wheel bearings, shaft drives, auxiliary mechanisms (generators, hydraulic steering, air pumps, fans, water pumps), etc. Losses account for approximately 10.5% of the fuel's thermal energy, and the potential for energy savings by reducing friction is considerable. Fluid lubricating and elastic fluid lubricating parts have the best viscosity (low viscosity, multi-grade oil) under various working conditions, and the boundary lubricating parts have excellent anti-friction and anti-wear properties (anti-friction agents). Direct energy savings. Lubricants that reduce part wear and extend component life can indirectly save energy. To further improve the lubricating performance, extreme pressure anti-wear performance and service life of grease, not only to develop new additives, but also to work on base oils, thickeners, fillers and their combinations to continuously develop new materials. The use of synthetic lubricants has proven to be an effective way to save energy and extend life.

    For a specific grease development project, we must first do a good job of investigation and research, understand the specific requirements of the customer or the market, make full use of the written information, physical information and existing experience, do a good test design, and then conduct laboratory development and simulation tests. , Use test, etc. During this period, the cooperation between the grease industry and the automotive industry is very important.
