Problems solved by technology

However, the traditional formula needs to spray a large amount of water to improve the cooling performance during the process, which not only consumes a large amount of energy but also produces a large amount of waste liquid, which causes certain environmental pollution, and also makes the oil used in the process only one-time use.
For many years, people have tried to find its substitutes: su

Embodiment Construction

[0011] A kind of preparation of stainless steel rolling oil, which is composed of the following raw materials by weight: 76.2% white oil, 12% neopentyl glycol ester, 6% pentaerythritol fatty acid ester, 2% isooctyl stearate , 0.8% mixed high temperature antioxidant, 0.2% 2.6 di-tert-butyl-p-cresol, 0.1% dipotassium EDTA, 0.5% T711, 0.2% T551, 2% T306.

[0012] Among them: the mixed high-temperature antioxidant is compounded by diisooctyldiphenylamine and mono-tert-octyl-α-naphthylamine, and the ratio of the two is diisooctyldiphenylamine:mono-tert-octylphenyl-α - Naphthylamine = 1.7:1.0. The white oil adopts 7#-10# white oil; the viscosity of the neopentyl polyol ester is 40°C (6.0~22mm 2 / s).

[0013] The blending process is as follows: firstly, the white oil of the formula quantity is put into a stainless steel (non-magnetic) blending kettle, and then the temperature is gradually raised to 80°C. During the heating process, the mixed antioxidant, 2.6 di-tert-butyl-p-cresol...

Abstract

The invention relates to a rolling oil for a stainless steel, which is prepared by the following raw materials by weight: 64.5-79.9% of white oil, 5-15% of neopentyl polyol ester, 5-10% of pentaerythritol aliphatic ester, 2-5% of isooctyl stearate or butyl stearate, 0.5-1.2% of mixed-type high temperature antioxygen, 0.05-0.2% of phenol-type antioxygen, 0.05-0.1% of ethylenediaminetetraacetic acid (EDTA) dipotassium salt, 0.4-0.8% of antirust additive, 0.1-0.5% of metal passivator and 2-3% of antiwear agent. The invention uses synthetic ester to replace chlorinated paraffin, which prevents environmental pollution of chlorinated paraffin, meanwhile avoids using large quantity of water for cooling, saves massive water source and also converts the processing oil into recyclable oil, thereby prolonging the service life of the processing oil greatly. The invention has the features of excellent lubrication performance, cooling performance, rust resistance, cleanness, energy conservation andenvironmental friendliness. The waste liquid is less in volume and can be recycled. Therefore the rolling oil provided by the invention is the preferred processing oil for finishing rolling of stainless steel to obtain high-gloss surface.

Description

technical field [0001] The present invention relates to a liquid composition used for lubricating, cooling, rust-proofing and cleaning in the processing of stainless steel finish rolling bright plate. Background technique [0002] Stainless steel plate (strip) processing is an important process in metal processing. As stainless steel products enter the civilian daily life (kitchen supplies) from the industrial field (such as decorative engineering), the application of this processing technology is becoming more and more extensive. This drives the continuous development and technological innovation of process oils that match this process. Traditional stainless steel rolling oils are manufactured with chlorine-containing additives such as chlorobenzene, hexachloroethane, chlorinated fatty acids, chlorinated paraffins, etc. Among them, chlorinated paraffin is the most commonly used because of its low price and good process quality. The reason why chlorine-containing products...
