Description
Technical field
The invention belongs to a kind of solid lubrication slide block in solid lubricant field and preparation method thereof, more particularly, to
A kind of molybdenum disulfide-bismaleimide solid lubrication slide block and preparation method thereof.
Background technique
The fretting wear of material is to cause the major reason of material failure, and friction can make the material surface temperature liter of material
High, energy consumption increases；Abrasion can destroy material surface shape and size, so that the stability of material reduces, eventually lead to workpiece
It destroys.China every year due to fretting wear caused by economic loss be up to hundred billion yuan.Extend part and mechanical service life, drop
The fretting wear of low material is an extremely urgent problem.
The ability for reducing fretting wear, the rub resistance abrasion for improving material is a weight for becoming engineering material in recent years
Want research field.Wherein, grease lubrication is the most common mode for reducing fretting wear, and grease lubrication is honest and clean in most cases
The settling mode that valence is easy to get, however in more demanding production environment, grease is since its lubrication contamination is big, top load under high temperature
Lower greasy property decline, it is difficult to meet requirement.Solid self-lubricating composite material is wide using temperature, bearing capacity is strong, physics
Stable chemical performance breaches the operating limit of conventional lubrication material, is widely used in heavy industry, electronics and aerospace etc.
Field is an important directions of lubrication technical field development.
Solid self-lubricating composite material can be divided into metallic based solid self-lubricating composite, inorganic non-solid self-lubricating is answered
Condensation material and polymer matrix solid self-lubricating composite material.Metallic based solid self-lubricating composite has good mechanics strong
Degree, but corrosion-vulnerable in use process；The hardness of inorganic non-solid self-lubricating composite is big, wearability is strong, but prepares
It is at high cost, post-production difficulty is big.The density low-friction coefficient of polymer matrix solid self-lubricating composite material is low and corrosion-resistant energy
Power is strong, however its heat resistance urgently improves.
Bismaleimide is with its excellent heat resistance, radiation hardness, anti-flammability, dimensionally stable, and good mechanical performance is wide
It is general to be applied in the industrial circles such as Aeronautics and Astronautics, machinery, electronics, as the resin matrix of advanced composite material, however its toughness
Difference, high intensity operate easy embrittlement；After general toughener is added, it is easy high temperature wear.
Molybdenum disulfide has unique sandwich structure, compares table as a kind of important two-dimensional layer nano material
Area is big, and thermal stability and chemical stability are good；Due to being combined between layers mainly by Van der Waals force for its layer structure, key
Can be low, it easily slides, reduces the fretting wear of itself and other materials；In addition, the multilayer chip structure easily slided is in shearing masterpiece
With the lower mobility that can effectively increase polymeric fluid, the processable type of reinforced polymeric material.However, molybdenum disulfide and its
His Material cladding, especially with polymeric matrix compound tense, interface compatibility is bad, and material fragility is caused to enhance and material
At elevated pressures fretting wear aggravation.Therefore, molybdenum disulfide is mainly used as composite lubricating film at present, and selects and do solid sliding block
Material is less.
Summary of the invention
In order to solve the problems, such as background technique, the invention proposes a kind of molybdenum disulfide-bismaleimide is solid
Body lubricates sliding block and preparation method thereof, by solid sliding block prepared by this method, has good intensity and toughness, has good
Furthermore good rub resistance and corrosion resistance has good wear resistance.
