Abstract

The invention discloses micaceous iron antirust paint for metals. Raw materials are micaceous iron, iron oxide red, aluminum paste, talc powder, zinc stearate, carbon black, tung oil, stillingia oil, polyacrylamide and potassium dichromate. The corrosion resistance is good, the viscosity is 85-125 s, and the covering powder is 260-300 g / cm<2>. The strength is high, adhesive force is at a first class, the micaceous iron antirust paint resists water for 20-40 d and has no abnormalities; and the micaceous iron antirust paint resists saline water for 10-30 d and does not bubble or drop. The surface dry requires 2-6 h, the hard dry requires 18-22 h, and the fineness is 10-30 microns. A preparation method is simple, the raw materials are simple and easy to obtain, and the micaceous iron antirust paint can be produced widely and replace existing materials continuously.

Description

technical field [0001] The invention relates to the technical field of metal materials, in particular to an antirust paint of mica iron for metal. Background technique [0002] Antirust paint is a coating that protects metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea water, etc. Mainly divided into two categories of physical and chemical antirust paint. The former relies on the proper coordination of pigments and paints to form a dense paint film to prevent the intrusion of corrosive substances, such as iron red, aluminum powder, graphite antirust paint, etc.; the latter relies on the chemical antirust effect of antirust pigments, such as cloud Iron, zinc yellow antirust paint, etc. Used for rust prevention of bridges, ships, pipelines and other metals. Anti-rust paint of cloud iron is a kind of paint mixed with cloud iron and drying oil. It has good permeability and wettability, soft paint film and strong adhesion, but it dries slowly. ...
