Embodiment 1

[0037] Weigh 70g of lanthanum phosphate hydrate, add it to 930g of sorbitan monooleate, and stir it at 120°C for 2 hours to form an environmentally friendly trace cutting fluid precursor.

[0038] The preparation method of above-mentioned sorbitan monooleate is: take by weighing sorbitan 1641.6g (10mol), oleic acid 2824.7g (10mol) respectively in the reactor, add 40g (85%) phosphoric acid and stir to heat To 210°C, fully react for 10 hours, depressurize and drain the water, which is sorbitan monooleate.

[0039] Take 100g of the environmentally friendly micro-cutting fluid precursor prepared above, 100g of Tween-80, 100g of sodium petroleum sulfonate, 50g of sodium lauroyl sarcosinate, 50g of triethanolamine, and 600g of isopropyl myristate. Stir for 30 minutes, that is an environmentally friendly micro-cutting fluid.

[0040] The environmentally friendly micro-cutting fluid prepared above has the following physical and chemical indicators after testing:

Embodiment 2

[0045] Weigh 100g of lanthanum phosphate hydrate, add it to 900g of glycerol monooleate, and stir it at 100°C for 3 hours, which is the environmental protection trace cutting fluid precursor.

[0046] Take 120g of the environment-friendly trace cutting fluid precursor prepared above, 100g of Tween-60, 120g of sodium petroleum sulfonate, 100g of sodium myristoyl sarcosinate, 60g of diethanolamine, and 500g of isopropyl myristate. Stir until it is an environmentally friendly micro-cutting fluid.

Embodiment 3

[0048] Weigh 80g of cerium phosphate hydrate and add it to 920g of sorbitan monolaurate and stir fully at 110°C for 2.5 hours, which is the environmental protection trace cutting fluid precursor.

[0049] Take 120g of the environment-friendly trace cutting fluid precursor prepared above, 110g of Tween-40, 100g of sodium petroleum sulfonate, 55g of oleoyl sarcosinate, 65g of monoethanolamine, and 550g of isopropyl myristate. Stir for 30 minutes, that is an environmentally friendly micro-cutting fluid.

Abstract

The invention provides environment-friendly microscale cutting fluid. The environment-friendly microscale cutting fluid is characterized in that components are mixed and blended at 40-60DEG C to be completely transparent, and the components include, by weight, 10%-20% of an environment-friendly microscale cutting fluid precursor, 10%-20% of polyhydroxy fatty acid ester polyoxyethylene ether, 10%-20% of petroleum sodium sulfonate, 5%-10% of sodium cocoyl sarcosinate, 5%-10% of alkylol amine and 50%-60% of isopropyl myristate. The environment-friendly microscale cutting fluid is used cooperatively with a microscale lubricating device, usage can be reduced to less than original 5%; good lubrication and cooling effects are achieved, and energy conservation and emission reduction and environment protect effects are remarkable.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to an environment-friendly trace cutting fluid and a preparation method thereof. Background technique [0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication and cooling. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators. Healthy body. Today, when energy conservation, emission reduction, environmental protection, and green manufacturing are advocated, a new metal cutting process is urgently needed. Micro-quantity lubrication technology is a new metal green processing technology developed in recent years. It is to use a micro-quantity lubrication system to spray a micro-quantity lubricating oil with good extreme pressure, anti-wear...
