Salt-fog-resistant and leakage-trace-resistant epoxy formula material for electric appliance insulating part and preparation method of epoxy formula material

The invention discloses a salt-fog-resistant and leakage-trace-resistant epoxy formula material for an electric appliance insulating part and a preparation method. The salt-fog-resistant and leakage-trace-resistant epoxy formula material for the electric appliance insulating part is prepared from the following components in parts by weight: 100 parts of epoxy resin; 80-85 parts of a curing agent; 420 to 550 parts of 400-mesh silica powder; 1 to 3 parts of nano Al2O3; and 2-7 parts of a toughening agent. The electric appliance insulating part prepared from the formula material can resist salt mist and electric leakage traces. 本发明公开了一种耐盐雾耐漏电痕的电器绝缘件用环氧配方材料及制备方法，耐盐雾耐漏电痕的电器绝缘件用环氧配方材料由以下组分按重量份组成：环氧树脂100份；固化剂80-85份；400目硅微粉420-550份；纳米Al2O31-3份；增韧剂2-7份。使用该配方材料制备的电器绝缘件，能够耐盐雾、耐漏电痕。
