Abstract

The invention discloses a titanium / copper laminated composite plate used for insoluble anode and a preparation method thereof, belonging to the fields of nonferrous metal extraction, chlorine alkali industry and the like. The titanium / copper laminated composite plate with the inner core being copper and an outer layer being coated with titanium is prepared by adopting an electric arc spraying method, a fusion casting method or a spray deposition method. The three methods have simple preparation technique and easy operation, and adapt to industrial production; the prepared titanium / copper laminated composite plate has excellent interface coherency, conductivity and corrosion resistance, a coating titanium anode prepared by adopting the laminated composite plate as a substrate leads the internal resistance of electrode to be reduced, the current distribution to be even and the product purity to be high; and the bath voltage is reduced by 0.1 to 0.8V, compared with that of the coating titanium electrode, thus achieving the effects of saving energy and reducing consumption.

Description

technical field [0001] The invention relates to a preparation method for an insoluble anode substrate titanium / copper layered composite plate used in fields such as nonferrous metal extraction and chlor-alkali industry. Background technique [0002] Titanium electrodes are widely used in non-ferrous metal extraction and chlor-alkali industry due to their excellent corrosion resistance and dimensional stability. However, traditional coated titanium electrodes use titanium or titanium alloys as substrates, which have defects such as large internal resistance and low current efficiency. At present, the research focus at home and abroad is mainly on the alloy system and coating to improve the performance of the electrode, but this method has no obvious effect on reducing the internal resistance of the electrode. [0003] The titanium / copper layered composite material integrates the excellent corrosion resistance of titanium and the good conductivity of copper. When applied to ti...
