The main application of wear-resisting carbon-fibre composite is that substituted metal material does the element parts such as gear, bearing, pulley, mechanical pump rotor, this requires that wear-resisting carbon-fibre composite has good mechanical strength and rigidity (modulus), therefore doing wear-resisting carbon-fibre composite preferably selects the better engineering plastics of mechanical property as polyether-ether-ketone (PEEK), polyphenylene sulfide (PPS), polyoxymethylene (POM), polymeric amide (nylon, PA) etc.; Secondly, though add tensile strength, the mechanical property such as flexural strength and modulus that carbon fiber significantly can improve matrix material, but too increase frictional coefficient and the wearing and tearing of material, therefore also need to add the less antiwear assistant of frictional coefficient when preparing wear-resisting carbon-fibre composite, conventional antiwear assistant has polytetrafluoroethylene (PTFE) resin, molybdenumdisulphide, graphite, silicone oil etc.The element parts such as gear, bearing, pulley, mechanical pump rotor are stressed members, and also need material to have good resistance to fatigue, this generally needs material to have higher shock strength.Traditional by adding impact modifying agent ［ graft copolymer (MBS), maleic anhydride grafted ethene-propylene diene copolymerized thing (EPDM) as methyl methacrylate-styrene-butadiene rubber ］ although to improve shock strength effectiveness comparison obvious, but the mechanical strength of composition and rigidity (modulus) decline obviously, also can increase frictional coefficient and the wearing and tearing of material simultaneously.As US Patent No. 20100120972 discloses a kind of method of fibre reinforced semiaromatic polyamide composition composition, embodiment 2 adds 5 parts of maleic anhydride grafted ethenes-propylene diene copolymerized thing (EPDM), the tensile strength of 40% fibre reinforced semiaromatic polyamide composition is 228MPa, and breach Izod is 7.21kJ/m
2, and the tensile strength that embodiment 1 does not add EPDM30% fibre reinforced semiaromatic polyamide composition is 272MPa, breach Izod is 5.95kJ/m
2though adding of visible impact modifying agent improves shock strength, and tensile strength greatly reduces.Therefore find that can to improve the method that material impact intensity do not reduce material mechanical performance be yet the target that researchist pursues.

In order to solve the problems of the technologies described above two, the technical solution used in the present invention is as follows: a kind of preparation method of wear-resisting carbon fiber reinforced nylon 66 resin combination, comprises the following steps:
I) Nylon 66, Nylon 6 is 80 ~ 100 DEG C of vacuum-dryings 8 ~ 12 hours;
II) dried Nylon 66, Nylon 6 and teflon resin and auxiliary agent are added melting mixing in twin screw extruder by required part by weight, twin-screw extruder barrel temperature is 250 ~ 300 DEG C;
III) continuous carbon fibre is from twin screw extruder intermediate openings introducing resin system, and continuous carbon fibre is sheared fragmentation in twin screw extruder, extrudes together with resin, and then pelletizing obtains described wear-resisting carbon fiber reinforced nylon 66 resin combination.
More specifically introduce the method for making of each component, technical requirements and compositing range below.
Component A: component A is Nylon 66, it is the polycondensate ［ poly-(hexamethylene adipamide) of hexanodioic acid and hexanediamine, PA66 ］, the mol ratio of hexanodioic acid and hexanediamine is generally 1: 1 in the course of the polymerization process, the molecular weight of polymkeric substance is by adding a small amount of acetic acid or hexanodioic acid regulates, also by the incompatible adjustment of the solid polycondensation after pelletizing, concrete production process can with reference to Chemical Industry Press (calendar year 2001) " engineering plastics " P43-65.The Nylon 66 that the present invention uses is poly-(hexamethylene adipamide) that can be used as the use of engineering plastics plastics, with intermediate molecular weight or high molecular as well, high molecular PA66 also can be taked to add the mode of a small amount of lower molecular weight PA66 to regulate the processing fluidity of composition.Nylon 66 content in the compositions of the present invention counts 45 ~ 70 parts with parts by weight, preferably 50 ~ 65 parts.
B component: B component is Nylon 6, i.e. polycaprolactam (PA6), industrial polycaprolactam is generally make hexanolactam ring-opening polymerization obtain in the presence of water, by regulating the molecular weight of the adjustable polycaprolactam of water-content in polymerization system, also increase the molecular weight of polycaprolactam by the method for solid state polymerization.The Nylon 6 that the present invention uses preferably adopts the polycaprolactam of high molecular, i.e. the relative viscosity polycaprolactam that is greater than 3.0.Nylon 6 content in the compositions of the present invention counts 1 ~ 20 part with parts by weight, preferably 2 ~ 15 parts.
Component C: component C is a kind of polytetrafluoroethylene (PTFE) powdex, in the compositions of the present invention the effect of main landing low-friction coefficient, because PTFE is the kind that in all plastics, frictional coefficient is minimum.Another reason that the present composition selects PTFE to make antifriction auxiliary agent is PTFE is that a kind of polymkeric substance is less on impacts such as the shock strengths of composition.This PTFE resin can be produced with suspension polymerization, has lower molecular weight, and powder diameter is at 1 ~ 20 micron, better with 2 ~ 10 microns.PTFE resin content in the compositions of the present invention counts 5 ~ 25 parts with parts by weight, preferably 5 ~ 20 parts.
Component D: component D is a kind of continuous carbon fibre, by being distributed in composition after the specific technique fragmentation of the present invention.This carbon fiber can pass through the operational paths such as polyacrylonitrile (PAN) spinning, drawing-off, oxidation, carbonization and produce (PAN base carbon fibre), also can produce (asphalt base carbon fiber) with special bituminous resins through operational paths such as spinning, oxidation, carbonizations.Carbon fiber is generally divided into different grades according to tensile strength and tensile modulus, there are standard modulus type carbon fiber (as T300, AS4, T700 etc.), middle model carbon fiber (as IM6, IM7 etc.), high model carbon fiber (as M55J, M60J, M65J etc.), the present invention mainly reduces the fragmentation of carbon fiber thus the performance of raising matrix material by specific technique, therefore has no particular limits carbon fiber grade.The carbon content of carbon fiber is very high, generally be greater than 90%, so its surface energy is lower, with other material in conjunction with poor, in order to improve this deficiency, the carbon fiber surface of business is generally coated with through special process (as anodic oxidation, strong acid corrosion etc.) resin (as epoxy resin etc.) that a small amount of (in 0.5 ~ 3% scope) improves cementability, and this is favourable often to raising composite property.Carbon fiber content in the compositions of the present invention counts 10 ~ 40 parts with parts by weight, preferably 15 ~ 40 parts.
Component E: component E is some auxiliary agents added to improve the impacts that contingent performance reduces in high temperature working processes such as Nylon 66, as prevented the oxidation inhibitor of Nylon 66 oxidative degradation, it also may be the compatilizer improving Nylon 66 and carbon fiber associativity.Oxidation inhibitor can be all kinds of hindered phenolic antioxidant (as Irganox1076, Irganox1010 etc.), phosphite ester kind antioxidant (as irgasfos 168,626,852 etc.) or their mixture.Compatilizer has styrene-maleic anhydride copolymer, ethylene-acrylate copolymer, epoxy resin etc.Component E content in the compositions of the present invention counts 0.01 ~ 5 part with parts by weight, preferably 0.1 ~ 2 part.
The present invention adopts and adds a small amount of Nylon 6 when fibre reinforced wear resistant nylon 66, the shock strength of wear-resisting carbon fiber reinforced nylon 66 resin combination can be improved, the simultaneously not mechanical property such as the tensile strength of loss portfolio thing and modulus in flexure, obtained wear-resisting carbon fiber reinforced nylon 66 resin combination has low frictional coefficient and wearing and tearing, shows to have good wearability.Why there is so good effect, we think because Nylon 6 is better than Nylon 66 with the bonding force of carbon fiber, Nylon 6 is also crystalline resin simultaneously, a small amount of Nylon 6 add the crystal density that can improve whole Nylon 66, therefore shock strength and wear resistance are improved.On the other hand, traditional carbon fiber of milling destroys serious to fibrous texture, and many carbon fibers are ground into Powdered, thus weaken the reinforced effects of engineering plastics; In addition, carbon fiber of milling is general all without good surface treatment, therefore neither be fine with the bonding force of engineering plastics.The present invention uses the fine surface-treated continuous carbon fibre of the obtainable process of business, in the course of processing, reduced the structure deteriorate of carbon fiber by adjustment screw rod block combiner as far as possible, thus obtain good wear-resisting carbon fiber reinforced nylon 66 resin combinations of mechanical property such as tensile strength, flexural strength and modulus.
Adopt technical scheme of the present invention, the wear-resisting carbon fiber reinforced nylon 66 resin combination notched Izod impact strength of gained reaches as high as 126 joules per meter, and unnotched impact strength can reach 1045 joules per meter, and wearing and tearing in 2 hours only 3.3 milligrams, achieve good technique effect.
Below by embodiment, the present invention is further elaborated.
