Embodiment 1

[0029] The raw materials and weight percentages are as follows: polyethylene glycol 10-14%, glycerin 16-20%, ethylene glycol 1-3%, sulfonated castor oil 3-5%, benzotriazole 0.4-0.6%, Industrial ethanol 2-3%, isothiazolinone 0.05-0.15%, deionized water 60-62%.

[0030] Each raw material can be selected within the weight range, so that the weight sum is 100%.

[0031] The production method is as follows:

[0032] a. First dissolve the benzotriazole with the calculated amount of industrial ethanol, and set aside;

[0033] b. Add the calculated amount of deionized water, polyethylene glycol, glycerol, and ethylene glycol into the reaction kettle in turn, start the stirrer, adjust the rotating speed to 200 rpm and continue stirring for 1 hour;

[0034] c. Add the standby materials obtained in step a, sulfonated castor oil and isothiazolinone to the reaction kettle in turn, and heat to 50-60°C for continuous stirring for 2 hours;

[0035] d. Just drop to room temperature.

Embodiment 2

[0037] The production method is the same as in Example 1, except that the raw materials and weight percentages are as follows: 12% polyethylene glycol, 18% glycerol, 2% ethylene glycol, 4% sulfonated castor oil, 0.5% benzotriazole, industrial ethanol 2.5%, isothiazolinone 0.1%, deionized water 61%.

[0038] The product stock solution of embodiment 1 and embodiment 2 of the present invention is used as lubricating oil.

Abstract

The invention discloses a water-based lubricant oil which is good in lubricate and cooling effect, low in cost, and meets environmental protection requirement, wherein the weight percentage of raw material is polyethyleneglycol 10-14%, glycyl alcohol 16-20%, ethandiol 1-3%, sulfonated castor oil 3-5%, benzotriazole 0.4-0.6%, industrial alcohol 2-3%, 2-methyl-3(2H)-isothiazolone 0.05-0.15%, deionized water 60-62%. The production process is dissolving benzotriazole with industrial alcohol of computed amount, standing by for service; adding deionized water, polyethyleneglycol, glycyl alcohol, ethandiol of computed amount sequentially into reactor, starting agitator, adjusting rotational speed to 200 rotates / min and stirring for one hour; adding standby prepared in step a, sulfonated castor oil and 2-methyl-3(2H)-Isothiazolone into reactor, heating to 50-60 DEG C and stirring for 2 hours; then cooling to normal temperature.

Description

Technical field: [0001] The invention relates to a lubricating oil, in particular to a water-based lubricating oil with good lubricating and cooling effects, low cost and meeting environmental protection requirements and a production method. Background technique: [0002] The components in the mechanical equipment provide the necessary power through the equipment to slide or rotate relative to each other, and friction will occur between two mechanical components that are in contact with each other. In order to reduce the friction force generated, reduce wear, prevent the frictional heat generated by the relative motion of the pair, prevent the surface corrosion of the mechanical components, prolong the service life of the mechanical components of the pair, and ensure the long-term normal operation of the mechanical components in the equipment, it is necessary to control the relative motion. Lubrication is applied to the two paired mechanical elements. Lubrication treatment ...
