Embodiment 1

[0018] The steel material of present embodiment 1 uses the manufacture method of the rust-proof antirust primer with low surface treatment. In a stainless steel bucket, first add 0.3 parts by weight xylene and 0.3 parts by weight n-butanol and mix uniformly, then add 1 Parts by weight of bisphenol A type epoxy resin was dissolved in advance, then stirred and added 0.3 parts by weight of tannic acid, after high-speed stirring for 0.5h, added 0.2 parts by weight of precipitated barium sulfate, 0.2 parts by weight of zinc phosphate, 0.2 parts by weight of Parts by weight of talcum powder, 0.2 parts by weight of iron oxide red, 0.01 parts by weight of ZBH-201 dimethyl silicone oil, 0.1 parts by weight of AFCONA-5010 polyester modified polyphosphate compound, and then circularly grind for 1 hour with a sand mill to make the Liquid A of the primer; add 0.4 parts by weight of xylene and 0.2 parts by weight of n-butanol to 1 part by weight of 651 polyamide resin, and mix evenly to make...

Embodiment 2

[0024] The steely material of present embodiment 2 mixes 0.01 weight part polymer in the rusty antirust primer A liquid with low surface treatment of the steely material identical with the manufacture method of the band rust-proof primer of low surface treatment with embodiment 1 Amide wax is made into the rust-proof primer A liquid with low surface treatment for steel materials; in the 651 polyamide resin of 1 weight part, add the xylene of 0.3 weight part and the n-butyl alcohol of 0.3 weight part, mix homogeneously Make the B liquid in this primer; During use, the A liquid of 1 weight part, the B liquid of 0.2 weight part are mixed and made the rust-proof primer with low surface treatment for steel materials.

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...
