Description

A kind of anti-aging self-locking nut molybdenum bisuphide dry lubricant and preparation method thereof
Technical field
The present invention relates to technical field of lubricant preparation, more particularly to a kind of anti-aging self-locking nut molybdenum bisuphide dry film Lubricant and preparation method thereof.
Background technology
In addition to the fastening effect with plain nut, also with locking property, its operation principle is usually self-locking nut Frictionally self-locking, can prevent tightening member in use from loosening, obscission occurring, and be widely used in Aeronautics and Astronautics and fly The fastening of the mechanical movable parts such as row device.Fretting wear is in industrial circle generally existing, ＂ cancers ＂ being referred to as in industry, self-locking Nut is not only due to various vibration environments during assembling or use and fretting wear damage easily occurs, and because many It is secondary be screwed into, back-out Jing often with occur parent metal phase mutual friction, bonding phenomenon, so as to the locking property for causing nut fails, And then impact is produced on the structure of overall machinery, and the reliability and service life of machinery are reduced, spraying lubricant is to reduce One of effective way of friction and reduction abrasion.
Dry lubricant is that kollag, anti-wear additive etc. are scattered in organic or inorganic binder system by one kind In, by the techniques such as spraying, brushing, dip-coating on friction means surface film forming reducing a kind of new profit of its friction and wear Sliding technology, especially organic binding dry film lubricant, using simple, easy construction, being applied to self-locking nut can be in height Effectively lubricate under the environment such as temperature, high load capacity, ultrahigh vacuum, Strong oxdiative reduction and intense radiation, be that current kind is most, apply most A wide class dry lubricant.For example《The Aero-Space development of thermosetting molybdenum bisuphide dry lubricant》The acid of one literary grace The thermosetting curing that the blending epoxy of acid anhydride, 601 and 618, colloid molybdenum bisuphide and special solvent and additive etc. are prepared into Molybdenum dry lubricant, as a result shows, not only adhesive force, anti-corrosive properties, resistant of high or low temperature and resistant to liquid medium are good for its film layer, and Stable work in work, coefficient of friction be low under hot vacuum environment, friction durability is long.
But, the protrusion of the molybdenum bisuphide dry film for using at present has the disadvantage the easy oxygen in air (especially in moist atmosphere) Change and lubrication failure occurs.Molybdenum bisuphide resolves into Mo and S at 1100 DEG C in vacuum；In atmosphere, when temperature is more than 400 DEG C When, significantly oxidation is produced, and generate molybdenum trioxide, affect its lubricity and its adhesive attraction to metal surface, therefore Molybdenum bisuphide can use to 350 DEG C in air, and fretting wear when temperature is high again all can increase, and the humidity for improving dry film is needed for this Property and resistance to elevated temperatures, additionally, the epoxy resin adhesive heat resistance that obtained dry lubricant is used in document is poor, It is one of the reason for causing dry lubricant heat resistance relatively poor, and the dry lubricant structure function in text is all more It is single, only with lubrication, be coated in self-locking nut surface and do not have a rust inhibition, and low bearing capacity, anticorrosive property it is poor, It is difficult to remove.
The content of the invention
The object of the invention is exactly to make up the defect of prior art, there is provided a kind of anti-aging self-locking nut molybdenum bisuphide Dry lubricant and preparation method thereof.
The present invention is achieved by the following technical solutions：
A kind of anti-aging self-locking nut molybdenum bisuphide dry lubricant, is prepared by the raw materials in：601 epoxy resin 89-90,618 epoxy resin 29-31, neoprene 10-11, molybdenum bisuphide 27-29, methyl hexahydrophthalic anhydride 3.1-3.4, nano-sized carbon It is SiClx 4.1-4.6, rare earth fluoride 5-7, alum 0.1-0.2, alumina silicate fibre 2-4, ethyl trimethoxy silane 0.2-0.4, sweet Oily triacetate 3-4, age resistor TPPD0.1-0.2, mixed solvent 56-59, described mixed solvent be by ethylene glycol monoethyl ether, Dimethylbenzene is mixed with acetone according to mass percent 1: 5: 4.
The described a kind of anti-aging self-locking nut preparation method of molybdenum bisuphide dry lubricant, comprises the following steps：
（1）By rare earth fluoride in drying box 100-120 DEG C of preheating and drying 1-2 hour, add mass fraction for 5-8% alum Solution ultrasonic grinding 20-30 minutes at 60-90 DEG C, it is spray-dried, it is cold in 1000-1100 DEG C of temperature lower calcination 15-20 minute But alumina silicate fibre grinding 20-30 minutes are added to obtain modified fluorinated rare earth to room temperature；
（2）By nanometer silicon carbide in drying box 100-120 DEG C of preheating and drying 1-2 hour, keeping temperature add ethyl trimethoxy Base silane stirs 10-15 minutes, is vacuum dried to obtain modified Nano carborundum；
（3）In 601 epoxy resin, 618 epoxy resin, neoprene input high mixer mixed solvent will be added to be warming up to 85-95 DEG C stir to whole dissolvings, add step（2）Material high-speed stirring 20-30 minutes obtain inorganic nanometer modified blending epoxy Liquid；
（4）By molybdenum bisuphide in 740-840 DEG C of calcination processing 30-40 minute, it is cooled to 110-120 DEG C and adds TG acid Ester, step（1）Material grinds 1-2 hours, and in 75-85 DEG C step is added（3）Material and other residual components ultrasonic disperse grindings 2-4 hours, discharging.
It is an advantage of the invention that：With molybdenum bisuphide as lubricant, S atom is exposed to molybdenum bisuphide to the present invention in molybdenum bisuphide The surface of crystal layer, chemical bond is formed so as to produce very strong adhesive attraction to metal surface with metal surface atom, is easily formed Transfer membrane, under various friction conditions, transfer membrane of the molybdenum bisuphide on metal is in obvious orientations, and its base surface is put down Row reduces fretting wear in metal surface, 601 epoxy resin, 618 epoxy resin is carried out into composite nano inoganic and is modified Afterwards as organic binder bond, the resistance to elevated temperatures and ageing resistace of binding agent is improved, finally again the modified fluorination of compatibility is dilute Soil is used as filler and other effective additives, hence it is evident that improve the lubricity and antirust anti-moisture performance of dry lubricant, obtained Dry lubricant and conventional fat lubrication ratio are compared with four large effects such as antirust, anti-aging, lubrication, cleaning, can allowing self-locking nut Excellent working condition is kept for a long time, is increased the service life.
