Description
Technical Field
The invention relates to the technical field of lubricating grease, in particular to anti-ultraviolet and anti-tarnishing lubricating grease.
Background
The lubricating grease is a thick grease-like semisolid used for a friction part of machinery to play roles of lubrication and sealing, is also used for a metal surface to play roles of filling gaps and preventing rust, is mainly prepared from mineral oil and a thickening agent, can be attached to a vertical surface at normal temperature without loss, can work at a friction part with opening or poor sealing, and has a holding point which cannot be replaced by other lubricants.
The grease can keep the shape of the grease without flowing, can be adhered to metal without sliding off, and when the grease is at high temperature or is subjected to external force exceeding a certain limit, it can generate flow like liquid, when the lubricating grease is sheared by moving parts in the machine, it can generate flow and lubricate, reduce friction and abrasion between moving surfaces, when the shearing action ceases, it returns to a certain consistency, the particular fluidity of the grease, which determines that it can be lubricated in areas not suitable for use with lubricating oils, and, moreover, because it is a semisolid substance, the sealing effect and the protection effect of the lubricating grease are better than those of lubricating oil, so the lubricating grease is widely applied, but the existing lubricating grease does not have the effects of ultraviolet resistance and discoloration resistance, the ultraviolet ray can accelerate the oxidation of the lubricating grease, the lubricating grease is easy to discolor, the deterioration of the lubricating grease is caused, and the using effect of the lubricating grease is influenced.
Disclosure of Invention
The invention aims to provide a grease with ultraviolet resistance and tarnish resistance, which solves the problem that the grease is easy to deteriorate due to the fact that the grease does not have ultraviolet resistance and tarnish resistance effects in the background technology.

2-4 parts of defoaming agent
Preferably, the base oil is any one of paraffin oil, polyalphaolefin base oil, synthetic ester oil or polyether synthetic base oil, and the lithium hydroxide is an inorganic substance, is white monoclinic fine crystal, has pungent taste and has strong basicity.
Preferably, the fatty acid is a compound composed of three elements of carbon, hydrogen and oxygen, and is a main component of neutral fat, phospholipid and glycolipid, the graphite is an allotrope of carbon and is a gray black opaque solid, the graphite belongs to a hexagonal crystal system and has complete lamellar cleavage, and the cleavage plane is mainly molecular bonds and has weak molecular attraction.
Preferably, the molybdenum disulfide is an inorganic substance, is a black solid powder with metallic luster, and the carbon black is amorphous carbon, is a light, loose and extremely fine black powder.
Preferably, the glycerol is colorless, odorless, sweet and clear and viscous liquid in appearance, is an organic substance, and the ultraviolet absorbent can strongly absorb ultraviolet rays with the wavelength of 290-400 nm.
Preferably, the light stabilizer is white crystal powder, the melting point is 95-98 ℃, and the decomposition temperature is above 280 ℃.
Preferably, the high-temperature-resistant auxiliary agent is a coating auxiliary agent capable of resisting more than 250 ℃.
The invention also provides a preparation method of the anti-ultraviolet and anti-tarnish lubricating grease, which comprises the following steps:
the method comprises the following steps: adding lithium hydroxide, fatty acid, a defoaming agent, glycerol and water into a saponification kettle, stirring for 2 hours at the temperature of 70-100 ℃ to perform saponification reaction, and continuously heating and dehydrating to obtain a solid;
step two: putting the solid in the step one into a drying device, and drying at 100-105 ℃ to obtain lithium stearate soap;
step three: putting the lithium stearate soap into a mixing kettle, heating and stirring to melt the lithium stearate soap into a soap solution;
step four: adding base oil, graphite, molybdenum disulfide, carbon black, an antioxidant, an ultraviolet absorbent, a light stabilizer and a high-temperature resistant auxiliary agent into the soap solution, cooling, and blending to obtain a mixture;
step five: the blended mixture is put into a homogenizer, and the mixture flows through a high-pressure homogenizing cavity with a special internal structure at a high speed under the action of ultrahigh pressure, so that the mixture generates a series of changes of physical, chemical, structural properties and the like, and the homogenizing effect is achieved;
step six: and finally, degassing the homogenized mixture.
Compared with the prior art, the invention has the beneficial effects that: the anti-ultraviolet anti-tarnishing lubricating grease can strongly absorb ultraviolet rays with the wavelength of 290-400 nm through the use of the ultraviolet absorber and the antioxidant, effectively prevents the lubricating grease from being oxidized and discolored, and the light stabilizer is used together with the antioxidant and the ultraviolet absorber, so that the anti-ultraviolet performance of the lubricating grease is further improved.
