Antistatic plastic composite material for electric power fitting and preparation method of antistatic plastic composite material

Abstract

The invention discloses an antistatic plastic composite material for an electric power fitting. The antistatic plastic composite material is prepared from the following raw materials in parts by weight: 100 parts of junked and abandoned nylon 66 plastic, 2.5 to 2.8 parts of polybutadiene epoxy resin, 23 to 27 parts of glass fiber, 9 to 10 parts of aluminum nitride, 1.7 to 1.9 parts of nano calcium carbonate, 6 to 8 parts of dimethyl formamide, 2.6 to 2.9 parts of triethylene glycol diisooctoate, 7 to 9 parts of silane coupling agent KH560, 11 to 13 parts of sericite powder, 1.4 to 1.7 parts of secondary-alkyl sulfonate and 4 to 6 parts of polyethylene wax. Nylon is modified into a matrix through the epoxy resin; the modified glass fiber is used as a reinforcing material; the nano calcium carbonate is added into the material after being subjected to graft modification treatment through the dimethyl formamide; afterwards, the composite material prepared by matching with other effective components is used for better solving the problems of magnetic hysteresis loss and eddy current loss, avoids electric energy loss, and has the advantages of being antistatic, resistant to wear and high in mechanical strength, and the like.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an antistatic plastic electric power fitting composite material and a manufacturing method thereof. Background technique [0002] Power fittings are metal accessories that connect and combine various devices in the power system to transmit mechanical loads, electrical loads and some kind of protection. They are important components in the power transmission process. At present, non-magnetic aluminum alloys are mainly used. Although compared with the ferromagnetic materials used before, they play a certain role in energy saving and emission reduction of the power grid, but as metal conductors, eddy current losses still exist, and power loss is still unavoidable. Products must be obtained through high energy consumption and high pollution processes such as ore dressing, mining, electrolysis, and smelting. They are industries restricted by the state and cannot meet the e...

Problems solved by technology

[0004] However, due to the high crystallinity of nylon and the gap in grain size, there are many microscopic defects in the nylon structure, resulting in poor creep performance, dimensional stability and notched impact strength. These shortcomings limit the application of nylon. Therefore, it is necessary to modify nylon to destroy the regularity of its molecular structure and reduce crystallization, and because electric fittings have been used outdoors for a long time and the environment is harsh, in addition to requiring the material to be resistant to water and aging, its wear resistance, antistatic, and electric resistance Performance such as halo and lightning protection also needs to be improved
