Anticorrosion coating composition for steel, especially for reinforcement steel in concrete

摘要

The invention preferably relates to a means of protecting reinforcement steel against corrosion in building materials and constructional elements made of silicate concrete, in which permanent passivation of the reinforcement steel is not ensured. By reducing the number of components in the formulation, especially those components which may damage human health, the intention is to develop an economically advantageous anticorrosion coating composition which, as a dipping lacquer, has improved rheological properties. This is achieved using known anti-rusting pigments, fillers, drying oils, drying agents (siccatives) and oxidised bitumen (blown bitumen) by a composition having the following mixing ratios in accordance with the invention: 6-13 M-% of linseed oil-tung oil (wood oil) stand oil or linseed oil stand oil (calorised linseed oil) 2-6 M-% of calcium stearate 15-30 M-% of aluminium silicate 8-14 M-% of red lead oxide (minium)
