Technical field
The invention belongs to preparation of greases technical fields, and in particular to a kind of heavy duty high/low temperature preparation of greases side Method.
Background technique
The fast development of modern society, market heave-load device is more and more, excavator, Mining machinery, crane etc., this A little equipment require the protection of lubricating grease in the process of running, equipment can be made to operate normally.And these equipment are run Most of environment be all it is outdoor, environment is more severe, have high temperature, have low temperature, and load is also bigger, used lubrication The necessary extreme pressure property of rouge is preferable, and north and south environmental difference is also bigger, and the lubricating grease extreme pressure property used now on the market is not Very well, the frequent grease up of heat source using equipment is needed, is wasted time, and influence the service life of equipment.Therefore it needs A lubricating grease suitable for these heave-load device running environment is developed, makes equipment lubrication protection in place, can normally make With raising working efficiency.
Summary of the invention
Against the above technical problems, the present invention provides a kind of each reasonable raw material proportioning and product comprehensive performance it is higher heavy High/low temperature preparation of greases method is carried, which not only can satisfy high and low temperature alternative variation, the severe ring such as sleet, sand and dust The long-acting lubrication and protection of counterweight load equipment bearing under border, can also be to having worn, and the friction part of spot corrosion is transported Dynamic restoring during row, solves the current limited technical problem of heave-load device Grease's lifetime, and the lubricating grease and The compatibility of other lubricating grease is preferable, is a kind of multifunctional multi-effect lubricating grease, has biodegradability, has very to environmental protection Big effect.
The present invention adopts the following technical scheme that solve above-mentioned technical problem, a kind of heavy duty high/low temperature preparation of greases side Method, it is characterised in that specific steps are as follows: the base oil of 60-65 parts by weight and the fatty acid of 5-10 parts by weight are mixed 1 in 80 DEG C Hour, it is warming up to the alkoxytitanium of 80-100 DEG C of addition 3-5 parts by weight and is saponified 1 hour, add the water and liter of 1-3 parts by weight Temperature to 100-210 DEG C thickening 4-6 hours, after water evaporating completely be added 10-15 parts by weight base oil and 0.5-1.5 parts by weight Antioxidant, stirring be cooled to 90 DEG C hereinafter, carry out it is cooling, grind to obtain heavily loaded height temperature lubricating grease, the base oil is low The poly alpha olefin mineral oil of viscosity and the miscella of synthetic oil, alkoxytitanium are one in four different oxygroup titaniums or four isopropyl ester of metatitanic acid The mixture of kind or both, fatty acid are one of ten dihydroxystearic acids, stearic acid or decanedioic acid or a variety of, and antioxidant is Phenyl-β-naphthylamine.
Heavy duty high/low temperature preparation of greases method of the present invention, it is characterised in that specific steps are as follows: by 65 weight The base oil of part and the fatty acid of 8 parts by weight mix 1 hour in 80 DEG C, are warming up to the alkoxytitanium of 90 DEG C of 4 parts by weight of addition simultaneously Saponification 1 hour adds the water of 3 parts by weight and is warming up to 180 DEG C of thickening 5 hours, 13 parts by weight are added after water evaporating completely Base oil and 1 parts by weight antioxidant, stirring be cooled to 90 DEG C hereinafter, carry out it is cooling, grind to obtain heavily loaded high/low temperature lubrication Rouge.
Heavy duty height temperature lubricating grease produced by the present invention has following excellent properties:
1, the high-temperature behavior of lubricating grease: the heavily loaded height temperature lubricating grease of preparation is that one kind is able to satisfy the multi-functional lubricating grease of high temperature, And have higher dropping point and lipid phase transition temperature, and the dropping point of heavily loaded height temperature lubricating grease are as follows: 294 DEG C, common compound lithium base lubrication The dropping point of rouge are as follows: 263 DEG C.
2, the low temperature torque of lubricating grease: the heavily loaded height temperature lubricating grease of preparation does -30 in low temperature torque testing machine of the same race DEG C two kinds of lubricating grease low-temperature tests, the staring torque 3500N/m of heavily loaded height temperature lubricating grease, operate torque 500N/m, commonly Complex lithium grease staring torque be 3125N/m, operate torque 237N/m.
3, environmental protection property: heavy duty height temperature lubricating grease obtained belongs to degradability lubricating grease, to the producer and user It is all safe, so heavily loaded height temperature lubricating grease is environmentally friendly friendly lubricating grease.
4, the describing property of lubricating grease: the compatibility of the heavily loaded height temperature lubricating grease and other lubricating grease of preparation is preferable, and The structure of lubricating grease is not also destroyed after heavily loaded height temperature lubricating grease addition organic additive, and additive effect has apparent dash forward Out, using effect is very good.
