Description
Technical field
Secondary composition of friction and its preparation method and application is repaired the present invention relates to a kind of.
Background technology
Liquid ceramics are a kind of new materials, it can substitute used in current lube product have larger dirt to environment
Dye, anti-wear and wear-resistant performance be general, with sulphur, phosphorus, chlorine element it is compound based on organic matter lubricating oil antiwear and friction-reducing additive, be tradition
The core technology product of the cross-centennial upgrading of lube product.
The performance of mechanical equipment and the precision of constitution equipment component are closely related.By taking automobile as an example, the performance and hair of automobile
The precision of the components such as motivation, gearbox, differential mechanism, transmission mechanism, hydraulic system and traveling mechanism is closely related.Since machinery is transported
Dynamic component there are intermetallic friction and wear, causes incomplete combustion, fuel consumption increase, vibration and noise to increase, automobile
It is short of power, exhaust emissions is exceeded, safety coefficient declines.
The friction and wear of machinery is the main reason for causing the excessively high mechanical energy consumption of all operatings and damage.According to relevant information
Statistics：The expenses such as maintenance, repair, stop work and production of the modern industry because rubbing, wearing generation account for gross national product
15%~30%.
Calculate according to related authoritative institution：In friction loss, machinery is set for 30%~50% consumption of the disposable energy in the world
Standby to damage and failure about 80% is as caused by friction abrasion, and the serious accident of more than 50% mechanical equipment is all due to
Excessive wear caused by lubrication failure.
The secondary abrasion of reduction friction is the most frequently used and most simple effective method is lubricated using lubriation material, lubricating oil
Or lubricating grease is the lubriation material generally used at present, since most of lubricating oil or lubricating grease are to generate one between friction is secondary
The thin lubricating oil film of layer, reduces coefficient of friction and abrasion, but this layer of oil film is more easily damaged in use, and easily becomes
Matter and fail, easily generate deposit, therefore lubricant effect is difficult to the requirement for meeting many application scenarios.
The defects of in order to make up lubricating oil, often adds in various organic matters or inorganic matter to increase in lubricating oil or lubricating grease
The greasy property of strong lubricant grease improves the bearing capacity of lubricating film and reduces coefficient of friction.
Since conventional lubrication is theoretical and lubrication product is established in the forties in last century and gradual perfection gets up, when so far
Day, antiwear additive on sale is mainly to use using sulphur, phosphorus, chlorine compound as component, lubrication based on chemical membrane mechanism in the market
Product.The secondary oil film temperature of friction be more than 130 DEG C, mechanical cold start-up, under stress alternation and overload condition, conventional lubrication product
Protection cannot be provided for friction pair.

Preferably, the condition of the drying is：The power of microwave drier is 8~15KW, the frequency of microwave for 800~
1000MHz, drying time are 5~10 minutes, and drying temperature is 80~120 DEG C.
It is a further object of the present invention to provide a kind of application of the secondary composition of reparation friction, the combinations
Object is added to as additive in lubricating oil.
It is added in lubricating oil, is filled into engine using the present composition as additive, normally transported in engine
During turning, the industrial sintering process for oozing pottery technique is substituted using friction pressure and frictional heat, it is former that metal occurs in metal surface
Sub- substitution reaction, soft dusty material are transformed into the cermet coating that hardness is high, wear-resistant, coefficient of friction is low, rub in metal
Wipe the interstitial solid solution of secondary surface generation ceramet.The infiltration of ceramic particle make common metal have ceramic material high temperature resistant,
Characteristic corrosion-resistant, with high hardness.The infiltration of ceramic particle makes surfaces of metallic rubbing pairs expand contact area, increase enabling capabilities,
It improves the finish of surface of friction pair, reduce coefficient of friction, complete the in-situ immobilization to engine friction pair.
In application process, the additive amount of the composition is adjusted according to the degree of wear of engine, preferably,
The addition weight percent of the composition is 5~15 ‰.
Preferably, other additives are further included in the lubricating oil, such as detersive, dispersant, viscosity modifier, anti-corrosion
Agent, antioxidant etc..
Fluid present invention ceramics repair materials use oiliness activator, and liquid ceramics ion surface atomicity ratio is big, table
Face can be high, has excellent adsorptivity, adhesiveness and chemical reactivity under frictional heat electrophoretic action, can be in related lubricating oil
Other additives are adsorbed onto in friction pair and form thickness up to the elastic oil film of 20 microns or more of activation together, and oil film thickness is
10~20 times of common oil film thickness add the elasticity and leakproofness of lubricating oil oil film, and various additives effect is made to be able to most
It gives full play to.
Compared with prior art, the invention has the advantages that：
(1) present invention changes the theory that conventional lubrication oil is protected with high viscosity, film lubrication, realizes surface of friction pair
Self-lubricating, selfreparing, from strengthen.Solve equipment cold start-up, stress alternation, impact load, the profit of full speed full load formation
