Embodiment 1

[0040] 116.07kg (1000mol) of maleic acid and 62.068kg (1000mol) of ethylene glycol are dropped into the polymerization kettle, add 0.89kg of dilute sulfuric acid (5%) and stir, then feed the air in the polymerization kettle into the protective gas conversion kettle, and at the same time Stir and heat up to 180°C. After 24 hours of polymerization, remove part of the water under reduced pressure to obtain polyethylene glycol butenedioate.

[0041] Add 5kg of the above-prepared polyethylene glycol succinate and 0.3kg of potassium tripolyphosphate into 94.7kg of alkaline electrolyzed water, mix and stir, prepare and adjust the solution with potassium hydroxide: an environmentally friendly Type long-life cutting fluid use.

[0042] The model of the electrolyzed water machine used to prepare the above alkaline electrolyzed water is: LF500B, and the pH value of the effluent is 9.30.

[0043] An environment-friendly long-life cutting fluid prepared above was used in BW60HS machining ...

Embodiment 2

[0050] Put 146.14kg (1000mol) of adipic acid and 106.12kg (1000mol) of diethylene glycol into the polymerization kettle by equimolarity, add 0.25kg of dilute sulfuric acid (10%) to stir, and then pass into the polymerization kettle to switch over the protective gas In the air, while stirring, the temperature is raised to 160 ° C. After 18 hours of polymerization, part of the water is removed under reduced pressure to obtain polyethylene glycol adipate.

[0051] Add 2 kg of polyethylene glycol adipate prepared above into 98 kg of alkaline electrolyzed water and mix and stir,

[0052] And use sodium oxide to adjust the solution to a pH value of 9.5, and prepare an environmentally friendly long-life cutting fluid for use.

Embodiment 3

[0054] Put 174.2kg (1000mol) of suberic acid and 150.17kg (1000mol) of triethylene glycol into the polymerization kettle, add 0.65kg of dilute sulfuric acid (6%) to stir, then pass into the polymerization kettle to protect the air in the conversion kettle , while stirring and raising the temperature to 170°C. After 21 hours of polymerization, remove part of the water under reduced pressure to obtain polyethylene glycol suberate.

[0055] Add 3kg of polyethylene glycol suberate prepared above, 0.3kg of potassium tetraborate, and 0.01kg of benzotriazole into 96.69kg of alkaline electrolyzed water, mix and stir, and adjust the solution to pH 9.8 with sodium hydroxide , an environmentally friendly long-life cutting fluid prepared for use.

Abstract

The invention provides an environment-friendly long-life cutting fluid, which is characterized by consisting of the following components by weight percentage: 2-5% of polyethylene glycol succinate, 95-98% of alkaline electrolysis water, 0-0.3% of phosphate, 0-0.3% of borate and 0-0.01% of benzotriazol. The major component polyethylene glycol succinate salt of the cutting fluid system provided by the invention is an anionic and non-ionic surface active agent, so even if a small amount of some other lubricating oil is introduced into a workpiece or a guide in the machining process, polyethylene glycol succinate salt can emulsify the lubricating oil into cutting fluid for usage, without reducing the usage performance.

Description

technical field [0001] The invention relates to the technical field of lubrication, in particular to an environment-friendly long-life cutting fluid and a preparation method thereof. Background technique [0002] Cutting oils, coolants, emulsions and other lubricants used in traditional metal processing lubrication and cooling are used in large quantities, and traditional cutting oils use mineral oil as the base oil, which is not easy to decompose in the natural environment. At the same time, cutting fluids often contain Add additives such as chlorides, sulfides, phosphides, alcohol amines, and nitrites that are harmful to the environment to solve the problems of lubrication, cooling, and rust prevention in micro-cutting. Most of these additives are harmful to the human body and the environment, not only wasting resources, but also causing huge pollution to the processing site and the environment. [0003] For example, the Chinese patent with the publication number CN101376...
