Description
Technical Field
The invention relates to the technical field of steel rolling oil, in particular to steel rolling oil and a preparation method thereof.
Background
With the continuous forward development of modern society, the living standard of people, especially the material condition, has changed with the ground, and stainless steel products are more and more widely applied to the fields of kitchen utensils, transportation, medical treatment, building industry and the like because of good performances such as corrosion resistance, high temperature resistance, high strength, exquisite surface and the like, and the stainless steel products become one of the indispensable main products in daily life of people, and steel rolling oil is often needed when high-quality steel is rolled.
However, in the face of increasingly severe processing conditions and process quality requirements, higher requirements are put forward on the performance of steel rolling oil, for example, high-quality steel needs better lubrication due to hardness higher than that of common carbon steel, and the steel rolling oil in the prior art often has insufficient lubrication, so that the plate surface has defects of scratches, color difference and the like, and therefore, improvement is needed.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provides steel rolling oil and a preparation method thereof.
In order to achieve the purpose, the invention adopts the following technical scheme: the steel rolling oil comprises the following components in percentage by weight:
50-70% of base oil, 10-20% of oiliness agent, 1-3% of extreme pressure antiwear agent, 0.1-0.5% of antioxidant, 0.2-1% of antirust agent, 0.1-0.2% of defoaming agent and 0.5-0.8% of emulsifier.
In order to improve the oil film strength, the invention improves that the base oil is three types of 60N base oil, and the oiliness agent is any one of cocoate, methyl palmitate and ethyl laurate.
In order to provide extreme pressure antiwear lubrication, the invention improves that the extreme pressure antiwear agent is any one or two of phosphite ester, phosphate amine salt, dibenzyl disulfide and sulfurized olefin cottonseed oil.
In order to slow down the oxidation of oil products, the invention improves that the antioxidant is any one of 2, 6-di-tert-butyl-p-cresol, dialkyl diphenylamine T534 and butyl octyl diphenylamine.
In order to avoid rusting, the invention improves that the antirust agent is any one of barium dinonylnaphthalene sulfonate, oil-soluble sulfonate, barium petroleum sulfonate T701 and alkenyl succinic acid half ester T747.
In order to reduce the generation of bubbles in the circulating process, the invention improves that the defoaming agent is any one of organic siloxane copolymer defoaming agent, polyether defoaming agent, dimethyl silicone oil and polyether modified organic silicon.
In order to increase the surface tension, the invention improves that the emulsifier is at least one of sorbitan fatty acid ester, cationic surfactant and nonionic surfactant.
A preparation method of steel rolling oil comprises the following steps:
s1, a preparation step, which is to prepare base oil, an oiliness agent, an extreme pressure antiwear agent, an antioxidant, an antirust agent, a defoaming agent and an emulsifier in percentage by weight and ensure that no impurity is doped in the base oil, the oiliness agent, the extreme pressure antiwear agent, the antioxidant, the antirust agent, the defoaming agent and the emulsifier;
s2, stirring, and then stirring the base oil and the oiliness agent, slowly raising the temperature to 50-60 ℃ in the stirring process, after the temperature is raised, increasing the stirring speed to 600-900r/min and stirring for 20-30min, so as to obtain a mixed solution A;
s3, reacting, namely injecting the mixed solution A into a reaction kettle, heating to 65-85 ℃, stirring for 40-50min, cooling to 35-40 ℃, adding an extreme pressure antiwear agent and an antioxidant, stirring for 10-15min, and cooling to room temperature;
s4, removing bubbles, then introducing the solution in the reaction kettle into a vacuum bubble removing machine for removing bubbles, wherein the vacuum degree of the vacuum bubble removing machine is between-0.02 and-0.04 MPa, the bubble removing time is 10-15min, and after the bubbles are removed, the solution is introduced back into the reaction kettle again;
and S5, finishing the processing, opening the reaction kettle for stirring, slowly adding the antirust agent after stirring for 5-10min, continuously stirring, simultaneously heating to 60-65 ℃, adding the defoaming agent and the emulsifier again after the heating is finished, and stirring for 1-2h to obtain the finished steel rolling oil.
