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
The invention belongs to lubricating grease field, particularly a kind of castor-oil plant base degradable plastic cement compound lithium base grease composite.
Background technology
The features such as plastics and matrix material tool light weight, inexpensive, rotational noise is little, production process is few, its intensity, close to metallic substance, can substitute non-ferrous metal and alloy use under many circumstances.Compared with common metal, plastics have special rubbing characteristics.Because the mechanical property variation range of plastics is very wide, and with intensity, rate of deformation and the failure procedure susceptibility to envrionment conditions, therefore comparatively metal is much complicated for the wear process of plastics.The interaction process of this complexity it has been generally acknowledged that: adhesive wear, chemical abrasion, abrasive wear and fatigue wear.Plastics also have certain self-lubricating property.The self-lubricating theory of engineering plastics has fully been confirmed and has been applied in engineering practice.But at present in the application scenario of many oil-free lubricatoins, engineering plastics exist that some are significantly not enough.As plastic gear mechanism etc. often cannot reach the work-ing life of expection, thus have impact on the application of plastic paste.This selection mainly due to plastic paste is improper, or lubricating grease select improper caused by.Plastic friction pair nearly all except only a few special plastic needs proper lubrication material to lubricate, otherwise the serious wearing and tearing of generation is even lost efficacy.Therefore, use lubricating grease to be harmful to very much indiscriminately.Therefore, be necessary to develop a kind of have good with plasthetics consistency, oilness, stability, weather resistance, low diffustivity, stability, wider use temperature scope, the castor-oil plant base degradable plastic cement compound lithium base grease composite of the loose contact corrosion-free to metallic substance, point of contact can not be caused.
Summary of the invention
The technical problem to be solved in the present invention be to provide a kind of have good with plasthetics consistency, oilness, stability, weather resistance, low diffustivity, stability, wider use temperature scope, the castor-oil plant base degradable plastic cement compound lithium base grease composite of the loose contact corrosion-free to metallic substance, point of contact can not be caused.
For solving the problems of the technologies described above, the present invention adopts following technical scheme:
