Description

Superhigh temperature special greases and preparation method
Technical field
Hmp grease drop point is up to 320 DEG C in the world at present, and temperature in use is 400 DEG C, this product superhigh temperature Grease dropping point temperature is 400 DEG C, and temperature in use is 1200 DEG C, and JDGWZ-5 type superhigh temperature special greases is a kind of high-end height Scientific and technological production technology, it is used under ultra-high temperature condition made of the mineral synthetic oil with specialist additive and thickening agent phase-polymerization Special greases, product used the solid-state liquifying method of unique innovation, high molecular nanometer compatibility new technology and nanometer polymerization Product new preparation process makes the drop point of product be increased to leading in the world 400 quickly by 320 DEG C of international most advanced level DEG C, product temperature in use is increased to leading in the world 1200 DEG C quickly by 300 DEG C of international most advanced level.
Technical background
Hmp grease dropping point is up to 320 DEG C both at home and abroad at present, and this product dropping point is up to 400 DEG C, high temperature resistant 1200 DEG C, which, using proving there is long lifespan, does not tie carbon, noncoking, radiation hardness, energy-saving and environmental protection, cost-effective through user It is a series of super to be widely used in machine-building, military project, guided missile, satellite, smelting, aviation, petrochemical industry, high-speed railway etc. for good characteristic The mechanical lubrication run under high temperature industrial and mineral.
The content of the invention
1st, technical formula component
2nd, production technology
By 1/2 mineral oil and synthetic oil, i.e. 150 BS and PA010, aliphatic acid and lithium hydroxide are anti-in 100 DEG C of progress saponification Should, reaction process answers strict temperature control, should fully react.Heating oil is added in after having reacted, by remaining 1/2 mineral oil and synthesis Oil is added in reaction kettle, is fully reacted, and reaction temperature control is 200 DEG C, when the reaction time is 1 small, including reaction With temperature control processing, temperature is then made to be cooled to 180 DEG C, carry out constant temperature processing, cool to 110 DEG C, add antioxidant, curing Molybdenum powder agent, oil-soluble graphite, are then sufficiently stirred, and are post-processed using homogenizer or circulation shear unit, filter, pack.
Specific embodiment
1st, JDGWZ-5 superhigh temperature special greases technical solution determine, mineral synthetic oil+multifunction additive+more work( It can thickening agent+high molecular polymer+inorganic solidified object+anti-particle ray polymer.
Raw material proportioning → raw material metering → charge ratio → heating supercharging → thickening reaction → temperature control reaction → isothermal reaction → high-efficiency polymerization → time is constant → and additive reaction → semi-finished product polymerization → constant temperature is constant → chemical examination → finished product → inspection → bag Dress → storage
2nd, operation process condition and its process innovation
Process conditions：Superhigh temperature special greases is under the jurisdiction of pole high-end product, produces each link and is in carefully controlled state It must strictly monitor.
Monitoring point：
1st, reaction temperature control 2, reaction speed control 3, reaction mass control
4th, Grade Control 5, reaction time control are reacted
Process choice Journal of Sex Research is the great innovation of ultra high temperature lubricating grease.This research and the research of constitution element consistency condition are tight The close research being connected, the purpose is to suitable product preparation process is selected according to the consistency condition of constitution element.This research bag Include the research of the special equipment of amplification production.This is determined by the characteristics of fine chemistry industry class product.General high temperature lubricating Fat preparation process is using more method preparation processes, still, in the research of this product, it has been found that due to newly adding " member Element ".It since its characteristic is apparent, can not be completed only with traditional handicraft, therefore, we carry out the innovation of technique, work out To mix more method superhigh temperature new processes.
In entire process procedure, processing step associated with temperature and time has been enriched so that preparation process increases New content, has reached the requirement of process for producing.Add corresponding technological equipment and detecting instrument simultaneously.
