A kind of ageing-resistant enamel insulated wire, including metal core and it is wrapped in the insulating layer of metal core outer layer, insulating layer is made of the insulating lacquer layer for being attached to the polyurethane insulating layer of metal wire wicking surface and brushing in polyurethane insulating layer outer surface, polyurethane insulating layer is made of polyether polyol, toluene di-isocyanate(TDI), epoxy resin, propylene glycol and modified filler I, and modified filler I is mixed by sepiolite cashmere powder, diatomite, modified manometer silicon dioxide and additive；The modified manometer silicon dioxide is to be mixed to get commercially available nano silica and the surface modifier of its weight 3-5%.The present invention is by successively wrapping up polyurethane insulating layer and insulating lacquer layer in metal wire wicking surface, so that ageing-resistant, the wear-resisting and corrosion resistance of enameled wire be greatly improved. |
