Preparation method of coated titanium electrode

Abstract

The invention discloses a preparation method of a coated titanium electrode, which comprises the following steps: step 1, preparing chloroplatinic acid coating liquid by using sponge platinum, step 2, preparing ruthenium iridium titanium coating liquid by using ruthenium chloride, chloroiridic acid, alcohol liquid and butyl titanate, step 3, pretreating the surface of a titanium substrate, and step 4, preparing the coated titanium electrode. The method comprises the following steps of 1, pre-treating a titanium base material, 2, coating the titanium base material with a platinum coating, 3, coating the titanium base material with a platinum coating, 4, coating the pre-treated titanium base material with a chloroplatinic acid coating solution, sintering, and cooling, 5, coating the titanium base material with the platinum coating with a ruthenium iridium titanium coating solution, sintering, and cooling, 6, repeating the step 5 for 8-20 times, and 7, detecting the service life of a finished product. The invention provides a preparation method of a coated titanium electrode, which effectively solves the problems that the service life of the existing coated titanium electrode cannot meet the requirements of users and the production and use cost of enterprises is high, and has the advantages that the service life of the coated titanium electrode can be prolonged, the product effect is ensured, the cost performance of the coated titanium electrode used by the enterprises is improved, and the service life of the coated titanium electrode is prolonged. The cost is reduced, and the energy efficiency is improved.

Description
