Abstract

The invention discloses a carbon nanotube-reinforced cyano carbon nanotube composite polyarylene ether nitrile composite material which is prepared from the following raw materials in parts by weight: 1.7-2 parts of 4-nitrophthalonitrile, 18-20 parts of multiwalled carbon nanotubes, 0.6-1 part of p-aminophenol, 58-70 parts of thionyl chloride, 100-130 parts of arylene ether nitrile, 0.1-0.3 part of ethylenebistearamide, 1-2 parts of triglycidyl Isocyanurate, 0.1-0.4 part of diphenyl imidazoline, 0.8-1 part of dodecyl propyl trimethoxysilane, 1-2 parts of zinc pyrithione, 4-6 parts of bone black, 2-3 parts of ammonium polyphosphate, 1-3 parts of alkenyl succinic anhydride, dimethylformamide, sulfuric acid, nitric acid and a proper amount of acetone. By virtue of the added carbon nanotubes, the hardness and the anti-impact strength of a finished product material can be effectively improved. The composite material is good in oxidation resistance, high in ageing resistance, good in storage stability and excellent in overall performance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to a carbon nanotube reinforced cyanocarbon nanotube composite polyarylether nitrile composite material and a preparation method thereof. Background technique [0002] Polyarylene ether nitrile is a kind of semi-crystalline polymer with excellent comprehensive performance, which has the advantages of high mechanical strength, flame retardancy, heat resistance and creep resistance, etc. It is expected to be used in the automotive industry, electronic appliances and aerospace play an important role in other fields. The main problem that has limited the application of PEN in special functional materials for a long time is the synthesis cost and processing fluidity of polymer PEN. Through years of research, our research group has mastered the low-cost synthesis technology of PEN, developed a series of PEN polymers to meet different needs, and developed the prepolymer phthal...
