Impact-resistant plastic electric power fitting composite material and making method thereof

Abstract

The invention discloses an impact-resistant plastic electric power fitting composite material. The composite material is made from, by weight, 100 parts of waste nylon 66 plastic, 2.1-2.4 parts of o-cresol formaldehyde epoxy resin, 20-21 parts of glass fibers, 1.1-1.4 parts of nanometer magnesium oxide, 18-20 parts of carbon black, 6-8 parts of a silane coupling agent KH550, 3-5 parts of chlorinated paraffin, 6-8 parts of a polyurethane emulsion and 4-6 parts of wheat straw fiber micro-powder. Nylon is modified with the epoxy resin to form a matrix, modified glass fibers are adopted as a reinforcement material, the nanometer magnesium oxide grafted and modified with the polyurethane emulsion is added to a material, and other effective components are adopted to prepare the composite material, so the composite material has the advantages of solving of hysteresis loss and eddy current loss, no electric energy loss, high impact resistance, high mechanical strength and long ageing resistance.

Description

technical field [0001] The invention relates to the technical field of composite materials, in particular to an impact-resistant plastic 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 econ...

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
