Description
Technical field
The invention belongs to high-temperature nylon material technical field, more particularly to a kind of nylon composite materials and preparation method thereof.
Background technology
High-temperature nylon resin refers generally to nylon engineering plastic of the modified long-term use of temperature more than 150 DEG C, at present work
The major product of industry includes amorphous nylon PA46 and semi-aromatic nylon PA4T, PA6T, PA9T and PA10T etc..High temperature Buddhist nun
Imperial resin has the advantages that good mechanical performance, wearability, heat resistance and the chemically-resistant property of medicine, semi-aromatic high-temperature nylon resin
Also overcome the shortcomings that nylon resin water absorption rate is high.High-temperature nylon resin can be used for sliding part and the structures such as gear, bearing, valve
Part, fuel conduit etc., but if using unmodified high-temperature nylon resin as high-abrasive material, especially lubricating condition compared with
Under poor or larger load working condition, its bearing capacity is inadequate, and self lubricity is poor, and wear extent is big in high-speed friction, it is difficult to
Meet the requirement of the self-lubricating structural timber for a long time with surface abrasion resistance damage and low frictional property under high loads.One
As for, addition carbon fiber and antiwear assistant can lift the performance of nylon resin.
Carbon fiber is high strength and modulus fiber of the phosphorus content more than 90%, is with a kind of strengthening material of excellent performance
Material.Carbon fiber and carbon fibre composite have high intensity, high-modulus, high temperature resistant, light weight, wear-resisting, creep resistant and thermal expansion
The advantages such as coefficient is low, are widely used in field of compound material.But carbon fiber surface is in chemical inertness, with thermoplastic
Compatibility is poor between property resin matrix, and carbon fiber is difficult to, with matrix resin Nian Jie poor, shadow dispersed in matrix resin difficulty
Ring the performance of composite material combination property.
The selection of antiwear assistant to improve high-abrasive material coefficient of friction and reduce high-abrasive material wear extent suffer to
Close important effect.It is generally acknowledged that the filler of soft, particularly Mohs' hardness be less than 2 filler, as graphite, molybdenum disulfide,
Talcum, mica and ptfe micropowder etc., abrasion of the coefficient of friction and can reduction of material to mating material can be reduced.But
Under larger load, when these high-abrasive materials occur to rub with respect to slip with the bigger mating material of hardness, part can be caused
Overheat, causes high temperature, and high-abrasive material can form adhesive wear because high temperature softens and is sheared and comes off.
Patent document CN101343409B discloses a kind of fibre reinforced thermoplas tic resin composite, using through surface
The thermoplastics such as carbon fiber reinforced nylon, makrolon, PET, polypropylene and ABS after processing, and
