Abstract

The invention discloses a castor-based biodegradable plastic composite lithium base lubricating grease composition. Poly-internal-olefin and castor-based diisodecyl sebacate are compounded to serve as base oil, and multiple composite additives including 12-hydroxystearic acid, an antioxidant, aids, lithium hydrate, a viscosity-temperature characteristic modifier, a light stabilizer, a mildew preventive, an antistatic agent, a light screener and a reinforcing agent are also used. The lubricating grease composition disclosed by the invention has good compatibility with plastic products, lubricating property, stability, durability, low diffusivity, stability and wide application temperature range, does not corrode metal materials, and does not cause bad contact of contact points.

Description

technical field [0001] The invention belongs to the field of lubricating grease, in particular to a castor-based degradable plastic composite lithium-based lubricating grease composition. Background technique [0002] Plastic and composite materials have the characteristics of light weight, low price, low transmission noise, and few production processes. Their strength is close to that of metal materials, and they can replace non-ferrous metals and alloys in many cases. Compared with ordinary metals, plastics have special friction characteristics. The wear process of plastics is much more complex than that of metals due to the wide range of mechanical properties of plastics, which are related to the strength, deformation rate, and sensitivity of the failure process to environmental conditions. This complex interaction process is generally considered to include: adhesive wear, chemical wear, abrasive wear and fatigue wear. Plastics also have certain self-lubricating propert...
