Technical field
The invention belongs to carbon-fibre composite technical field, be specifically related to excellent carbon fiber reinforced nylon 66 composite material of a kind of heat resistance aging resistance and preparation method thereof.
Background technology
Nylon66 fiber (polyhexamethylene adipamide) is a kind of broad-spectrum engineering plastics, formed by hexanediamine, hexanodioic acid polycondensation, compared with Other Engineering plastics, there is excellent mechanical property, as high strength, high-modulus, high rigidity, good thermal characteristics, higher heat-drawn wire, excellent self lubricity, antifatigue, creep resistant, good oil resistant and solvent borne etc.Be widely used in fields such as automotive industry, electronics, precision instruments.In recent years, along with the high performance in these fields, had higher requirement in the aspect such as intensity, hardness, rigidity, thermotolerance of the nylon66 fiber as structural material.But due to the wetting ability of amide group in nylon66 fiber molecule, the water-absorbent of nylon66 fiber is strong, easily by hydrothermal aging, thus can not meet the service requirements of association area.
In order to improve the wet and heat ageing resistant performance of nylon66 fiber, prior art mainly contains two kinds: 1, by the method for acid amides and other monomer block copolymerization is prepared the aging multipolymer of heat resistance (as patent CN101024695A), but the method can lose the mechanical strength of nylon66 fiber itself.2, the wet and heat ageing resistant performance (as patent CN101914289A) of nylon66 fiber is improved by adding glass fibre, but glass fibre belongs to mineral filler, they and organic nylon 66 material consistency are poor, the bonding interface of glass fibre and nylon66 fiber is not strong, cause the strength and modulus of nylon66 fiber itself to improve not obvious, thus limit the application of nylon 66 composite material.
Carbon fiber is the tencel material of the high strength of carbon content more than 95%, high-modulus.The advantages such as have density low, heat resistance is aging, and superhigh temperature resistant is corrosion-resistant, and thermal expansivity is little.Therefore can carry out reinforced PA66 with carbon fiber, improve the heat resistance aging resistance of nylon66 fiber.Compared with prior art, instant invention overcomes the shortcoming that in conventional art, nylon 66 composite material heat resistance aging resistance, both mechanical properties can not be taken into account, extend the Application Areas of Nylon 66.

3.
For the content of carbon fiber, body series has strict regulation, when short carbon fiber content is less than 20 parts, not remarkable to the raising of the mechanical property of nylon66 fiber, heat resistance aging resistance.Carbon fiber content is higher, and mechanical property and the heat resistance aging resistance of nylon66 fiber are better.But when the mass percent of carbon fiber is too high, when its content is greater than 80 parts, to the serious wear of mixing equipment, shorten the work-ing life of screw rod.In addition, too high levels can make that the melt viscosity of matrix material is high, fluidity of molten declines, and it is unfavorable thus to bring forming process, is especially unfavorable for the shaping of thin-walled, complex construction goods.
