Abstract

The invention discloses an anti-rusting and anticorrosive paint for steel and iron and a preparation method thereof. Solid red lead, vinylacetylene, ethylenediamine, aluminum powder, dibutyl phthalate, acetone, anthracene oil, coal pitch, talcum powder, mica powder, iron oxide red, zinc chrome, wollastonite powder and cyclohexanone are weighed and taken; the raw materials are agitated, and then are ground, so as to prepare the anti-rusting and anticorrosive paint for the steel and the iron. The anti-rusting and anticorrosive paint for the steel and the iron has favorable bonding strength to metal of the steel, the iron and the like, adapts to cold contraction, does not fall off, does not crack, has bonding strength of 4.2MPa to 4.6MPa, viscosity of 20s to 60s, flexibility of 1mm to 3mm, adhesive force of level 1, heat resistance which does not change within 8h to 12h at 100 DEG C, shock strength of 50kg / cm to 90kg / cm, fineness of 20 to 30 microns, solid content of 40 to 60 percent and good durability, has quite good acid resistance, alkali resistance and chemical corrosion resistance, and has quite good heat resistance and mechanical properties.

Description

technical field [0001] The invention relates to a coating for iron and steel surfaces, in particular to an antirust and anticorrosion coating for iron and steel and a preparation method thereof. Background technique [0002] Antirust coatings are coatings that protect metal surfaces from chemical or electrochemical corrosion from the atmosphere, sea dibutyl phthalate, etc. Coating anti-rust coatings on the metal surface can effectively prevent the direct invasion of various corrosive substances in the atmosphere, so as to maximize the extension of the service life of the metal. It can be divided into two categories: 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 red Dan, anthracene oil antirust p...
