Structural plastics, mostly general modified plastics, such as modified polyolefin, ABS, polystyrene, etc., are used in automotive parts such as door interiors, instrument panels, and device housings. In the application process of structural plastics, there seem to be few applications that require a lot of lubrication, but during the sliding and connection of parts, proper lubrication can reduce noise, vibration and the feeling of movement. In this case, checking the compatibility of structural plastics and lubricants is more important than functional plastics, and lubricants that will dissolve or corrode plastics cannot be selected. In addition, beware of chemicals that can cause cracks and cracks in the plastic. If these factors are ignored, there will be problems with the appearance or function of the parts, such as a brake system failure.
Appearance is an important consideration when choosing a lubricant. Where lubricants can be seen, transparent or translucent products are often required, and lubricants that will not stick to the body when the driver and passengers are in contact are often required. Dry film and semi-dry film lubricants can meet this requirement. After coating the lubricating film and before curing it, it is necessary to check the compatibility, because many dry film lubricants contain solvents that discolor and crack the plastic.
At present, poly-α-olefin base oil is a popular choice as a substitute for mineral oil and is very suitable for many plastics. Perfluoropolyether is a chemically inert lubricant that will not corrode plastics and can be applied to many types of plastics. However, due to the high price, its use is subject to certain restrictions. However, with the continuous development of new lubricants, the lubrication problem of automotive plastic parts will be satisfactorily resolved.
