Abstract

The invention provides alcohol ether phosphate which is characterized by being prepared from the following substances: fatty alcohol, ethylene oxide, epoxypropane, and phosphorus pentoxide, wherein the molar ratio of fatty alcohol, ethylene oxide, epoxypropane and phosphorus pentoxide is 1:(5-10):(1-2):(0.3-1). The prepared alcohol ether phosphate has the advantages of excellent lubricity, extreme-pressure wear resistance, antirust performance, and relatively good water solubility, at the same time, also is an excellent surfactant, can totally or partly replace traditional extreme-pressure anti-wear agents containing chlorine, sulfur and phosphorus to be used in a trace cutting fluid; only a small amount of the trace cutting fluid can satisfy metal processing requirements of lubricating, cooling, extreme-pressure wear resistance and rust resistance; with cooperation of a trace lubrication device, the usage amount of the cutting fluid can be saved 90% or more, and the effects of energy saving, emission reduction and environmental protection are significant.

Description

technical field

[0001] The invention belongs to the technical field of lubrication, and relates to an alcohol ether phosphate ester, a preparation method thereof, and a micro cutting fluid prepared by using the ester. Background technique

[0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. 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. In order to solve these problems, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology has solved the above problems such as large amount of lubricant used and serious pollution. The main problem is that the lubrication and cooling problems cannot be solved well.

[0003] In addition, micro lubricants often need to add a...

Examples

Embodiment 1

[0042] Step 1: Take by weighing 186.38kg (1000mol) of lauryl alcohol and 5.5kg potassium hydroxide (50%) in the solution reaction kettle, fill with nitrogen to convert the air in the reaction kettle, when the nitrogen in the polymerization kettle maintains positive pressure, use nitrogen to enter Push the mixture of 308.35kg (7000mol) ethylene oxide and 58.08kg (1000mol) propylene oxide into the reaction kettle while stirring to raise the temperature to 120°C and keep the reaction temperature not exceeding 120°C. The reaction time is 6 hours, which is Polyoxyethylene Laureth(7) Polyoxypropylene(1) Ether.
