1. a kind of electrolytic aluminium pre-roasting anode antioxidizing paint, which is characterized in that the component and mass percent of the coating are as follows:

  • Ceramic base continuous phase;

    by α

    -Al2O3And γ

    -Al2O3Composition, accounts for the 25% ~ 40% of coating gross mass;

    Ceramic base continuous catalysis phase;

    it is made of mica powder, feldspar in powder, rare earth ore concentrate fergusonite, accounts for the 20% of coating gross mass~40%;

    Alkali and alkaline-earth metal auxiliary catalysis phase;

    it is made of potassium hydroxide, sodium hydroxide, magnesium fluoride, water, accounts for the 5% of coating gross mass~10%;

    Ceramic base reinforcement phase;

    being made of calcined diatomite, montmorillonite, accounts for the 2% ~ 5% of coating gross mass;

    Stable phase;

    being made of silane coupling agent, aluminate coupling agent, is respectively used to ceramic base reinforcement phase, ceramic base continuous phaseSurface is modified, accounts for the 0.1% ~ 0.4% of coating gross mass;

    Film forming phase;

    it is made of methylcellulose, accounts for the 0.5% ~ 2% of coating gross mass;

    Water phase;
