2/ PA matrix material and preparation method thereof.
Background technology
Nylon has good mechanical property, and wear-resisting, oil resistant, resistance to solvent, self-lubricity, be one of broad-spectrum engineering plastics.Conventionally the volume specific resistance of polymeric amide is all greater than 10
15Ω, along with constantly increasing in the application aspect electronic apparatus, improves constantly the requirement of its conductivity.Due to the market requirement, much require material itself to have good antistatic effect, or conductive effect, so that material can be used in electromagnetic shielding field or require anlistatig occasion.
The preparation of polyamide electroconductive matrix material mainly realizes by adding various conductive filler materials, the most frequently used conductive filler material is graphitized carbon black at present, electrically conductive graphite or carbon fiber, conventional method is all to improve the electroconductibility of polymeric amide as filler by adding graphitized carbon black or electrically conductive graphite.Although added in addition other materials as additional conductive agent, graphitized carbon black plays a major role in system the inside.Along with Nano-technology Development, carbon nanotube and Graphene are also applied to electrically conductive polyamide matrix material as a kind of filler, but normal and other electro-conductive materials mixing uses such as carbon black and carbon fiber could obtain good electroconductibility.Above-mentioned electrically conductive polyamide material, although there is good electroconductibility, its inevitable shortcoming be exactly color can only be that black and processing characteristics are poor.Another kind of conventional conductive filler material is surfactant-based or high score subclass additive, as application number be CN200710172871.1 a kind of flame-retardant antistatic reinforced nylon 6 composition and preparation method, CN201110298092.2 Antistatic nylon material and preparation method thereof, has added high score subclass static inhibitor.In use there are a lot of shortcomings in this class static inhibitor, as antistatic effect lack permanent, add decomposes in man-hour, and the feature such as conduction rate variance.
