Abstract
An aluminium strip material with an insulating coating is characterized by comprising a base material bottom layer and a special coating material surface course for the insulating coating. The surface course comprises the following components in proportion by weight: 55-65 percent of solvent-based polyester resin, 15-25 percent of saturated polyester resin, 4-8 percent of assistant, 0.5-1.5 percent of catalyst, 0.5-1.5 percent of delusterant, 0.4-0.8 percent of levelling agent, and solvent accounting for the rest percentage. The chemical composition of the solvent-based polyester resin as well as of the saturated polyester resin is polyethylene glycol terephthalate; the solvent is butyl ether solvent, butanol solvent or solvent gasoline; the assistant is composed of unsaturated fatty acid polyamine amide salt and acidic polyester; the catalyst is high polymer supported catalyst; the delusterant is composed of active hydroxymethyl; and the levelling agent is composed of polysilicone-polyether copolymer. The practice shows that the aluminium strip material still has a favorable insulating property after being formed by stamping on the housing of an electrolytic capacitor, the insulating resistance of a surface course film reaches 1.1 to 1.5 megohm, and the surface course film is free of the phenomena of color changing, layering and bubbling during a test under 250 DEG C in one minute.
