Anti-rust primer for elementary surface treatment of steel material, and manufacturing method thereof

Abstract

The invention relates to an antirust primer with rust and with elementary surface treatment used for steel materials and a manufacturing method, wherein, fluid A is made by mixing, agitating and grinding bisphenol-A epoxy resin, dimethylbenzene, n-butyl alcohol, tannin, precipitated barium sulfate, zinc phosphate, saponite, iron oxide red, simethicone, polyester modified polyphosphonate compound and polyamide wax micropowder, while fluid B is made from polyamide resin, the dimethylbenzene and the n-butyl alcohol; when in use, mix and cure the fluid A and the fluid B to form the coating film. The antirust primer with rust and with elementary surface treatment has excellent adhesion and corrosion resistance, which can be coated on steel surfaces with uneven rust, solid oxide scale residuals or old paint, and can be directly used and matched as a primer with other finish paints without using any other primers.

Description

technical field

[0001] The invention relates to a low-surface-treated anti-rust primer for steel materials and a manufacturing method thereof, which are used for anti-corrosion of steel surfaces with uneven corrosion, residual solid scale or old paint. Background technique

[0002] Existing rust-bearing coatings can be divided into conversion type, stable type, and chelation-to-rust type. The advantage of the conversion type rust coating is that it can convert heavy rust and the conversion speed is fast. The disadvantage is that it is difficult to grasp the relationship between the thickness of the rust layer and the amount of coating, and it cannot be used as a real primer; the advantage of the stable rust coating is that it can be widely used and can It can be used on the steel surface with uneven corrosion, residual solid scale or old paint, and can be directly used as a primer with other topcoats. The disadvantage is that it can only be applied to steel surfaces with lig...
