Problems solved by technology
[0004] However, because nylon material is a flammable material, electrical fittings have been used outdoors for a long time, especially in hot summer and dry winter, which is easy to cause fire, and the improvement of the material's flame retardancy, cold resistance, and aging resistance has not been elaborated in the literature. Therefore, the development of a multi-functional, high-efficiency, energy-saving and flame-retardant modified composite nylon material for electric power fittings has a good application prospect

Abstract
The invention discloses a flame retardant nylon composite material for anti-impact electric power fittings. The flame retardant nylon composite material is prepared from, by weight, 75-79 parts of nylon 66, 23-25 parts of ABS resin, 21-22 parts of carbon fiber, 10-12 parts of basalt fiber, 8.6-9.2 parts of melamine cyanurate, 20-24 parts of beryllium oxide, 2.2-2.6 parts of hexamethyldisilazane, 3.1-3.4 parts of ethylene bisstearamide, 8-10 parts of methyl triacetoxyborohydride silane, 1.8-2.1 parts of nano bamboo charcoal powder and 4-5 parts of soybean concentrated protein powder. Melamine cyanurate is used as fire retardant, beryllium oxide obtained after silane modification is used as heat conducting filler, carbon fiber is used as a reinforcing material and matched with other effective components for mutual compounding, and the manufactured electric power fittings have the advantages of being resistant to impact and heat, flame retardant, long in service life and the like.
Description
technical field [0001] The invention relates to the technical field of composite materials, in particular to a flame-retardant nylon composite material for impact-resistant electric fittings 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. As an indispensable part of the power transmission line, its power loss has always been the focus of the power sector question. In addition to improving the casting process of electric power fittings, the selection of its materials is particularly important. At present, the main preparation materials are non-magnetic aluminum alloys. 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 a metal conductor, eddy current loss still exists, and electric ...
