Straight carbon steel cold-rolled sheet anti-rust oil combination

Abstract

The invention discloses straight carbon steel cold-rolled sheet anti-rust oil combination which comprises the following components by weight percent: 15 to 17 percent of magnesium petroleum sulfonate, 8 to 10 percent of zinc naphthenate, 12 to 14 percent of N-oleoyl amino-acid octadecylamine, 6 to 7 percent of nonyl phenol polyoxyethylene ether, 16 to 18 percent of natural animal and vegetable oil, 4 to 6 percent of 2,6-di-tert-butyl-4-methylphenol, 3 to 5 percent of 2,6-di-tert-butyl phenol and mineral oil in balancing amount, wherein the kinematic viscosity of the mineral oil is 33 to 35 mm<2> / s at 45 DEG C.

Description

technical field [0001] The invention relates to the technical field of antirust oil compositions for iron and steel, in particular to antirust oil compositions for common carbon steel cold-rolled plates. Background technique [0002] The surface anti-rust protection technology of metal plates and strips has always been a field of research by countries all over the world. There are some problems in the process of strip anti-rust protection. The reasons are various. In addition to insufficient research on anti-rust materials and the overall level is not high, another main reason is poor anti-rust process equipment and low automation. The traditional antirust treatment of metal sheets and strips is to use a roller oiler to apply antirust oil, spray the antirust oil on the felt roller through the nozzle, and then roll it onto the surface of the sheet and strip. This method of coating anti-rust oil mainly has the following disadvantages: ① often occur phenomenon such as missing ...

AI Technical Summary

Problems solved by technology

This method of coating anti-rust oil mainly has the following disadvantages: ① often occur phenomenon such as missing coating, uneven oiling, etc., the oiling effect is poor, and the anti-rust purpose cannot be achieved; ② the amount of oil applied is large and If it cannot be controlled accurately, it will cause a lot of waste of anti-rust oil, collapse and environmental pollution, and will increase the workload of subsequent processes and increase its production cost

③The life of the felt roller in contact with the moving strip is very short, which not only increases the production cost, but also reduces the operating rate

The composition has poor lubricating performance, and during the steel plate coiling process, due to the large tension, interlayer slippage is caused, resulting in scratches on the steel plate, and this scratch can affect the antirust performance of the composition and the surface quality of the steel plate

[0005] CN101486945A discloses a classic anti-rust oil sprayed and its production method, although its lubricating performance is better, but practice shows that its anti-rust performance is not very ideal
