Description
Technical field
The present invention relates to Ti electrode technical field, especially a kind of environment-friendly water-soluble platinum salt Ti electrode masking liquid.
Background technology
After coated titanium electrode comes out, the performance of incomparable brilliance is shown, extensive use is obtained in many electrolytic industries quickly,
Very big benefit is brought to national economy.
Coated titanium electrode is to put into pass through high temperature sintering in Muffle furnace after coating masking liquid on the Titanium base by preceding processing
Obtained, wherein masking liquid and coating processes are the most important things of whole Ti electrode production technology, and the quality of masking liquid directly affects electricity
The outward appearance and quality of pole, coating processes directly affect coating binding force and electrode performance.Existing many platinum salt masking liquids are produced
The platinum adhesion difference and the outward appearance of electrode that the electrode come easily causes electrode are yellow, black, grey and uneven, electrode outward appearance conduct
The index of a most direct most convenient of electrode performance is weighed, outward appearance is bad, mean that coating is uneven and coating structure everywhere
It is different, and coating is uneven, structure is different and coating can have a great impact with reference to bad to the performance of electrode；It is existing in addition
Masking liquid many poisonous and hazardous materials are often added in masking liquid, such as methanol, phenols, hydrazine are not environmentally friendly enough.
The content of the invention
In view of the deficiencies of the prior art, it is an object of the invention to provide a kind of uniform clean white bright, performance is good, adhesion
Strong environment-friendly water-soluble platinum salt Ti electrode masking liquid.
To achieve the above object, the technical solution adopted in the present invention is：
A kind of environment-friendly water-soluble platinum salt Ti electrode masking liquid, is made up of, wherein each group dispersant, reactive adhesive, water and platinum salt
Part percentage by weight is respectively：Platinum salt 6-12%, dispersant 25-40%, water 30-60%, reactive adhesive 5-10%.
It is preferred that, the platinum salt be chloroplatinic acid, hydroxyl platinic acid, P salt, the ammino platinum of dichloro two, one kind in divalence class platinum salt or
Two kinds.
It is preferred that, the dispersant is one or both of ethanol, ethylene glycol, polyethylene glycol, propane diols, n-butanol.
It is preferred that, the water is high alkalinity pure water.
It is preferred that, the reactive adhesive is one or both of vitamin C, tartaric acid, acetic acid.
Compared with the platinum salt masking liquid of currently the majority, environment-friendly water-soluble platinum salt Ti electrode masking liquid of the invention has platinum
Coating uniform, clean, Bai Liang, the advantage that platinum adhesion is strong, electrode performance is good.
