Abstract

The invention discloses an aluminum alloy near-dry cutting processing microemulsion and a preparation method thereof. The aluminum alloy near-dry cutting processing microemulsion is prepared through the following steps: preparing a mother solution, wherein the mother solution is prepared by mixing raw materials, heating to 30-50 DEG C and stirring, and the mother solution comprises the following raw materials in percentage by weight: 25-35% of polyalcohol oleate, 10-15% of sorbitan fatty acid ester, 10-15% of polyethenoxy ether nonionic surfactant, 5-10% of anionic surfactant, 5-10% of sulfurized fat, 2-5% of C3-6 monobasic alcohol, 1-3% of phosphate, 1-3% of potassium borate and 25-35% of water; and mixing the mother solution and water according to a weight ratio of 1:(1-3), sufficiently stirring, adding 0.005-0.01wt% of polysiloxane, and sufficiently stirring to obtain the aluminum alloy near-dry cutting processing microemulsion working fluid. The aluminum alloy near-dry cutting processing microemulsion disclosed by the invention has excellent extreme pressure performance, antiwear property and lubricating property; when the microemulsion is used with a near-dry cutting and lubricating device, the consumption of the microemulsion can be reduced to 10% or below of the original consumption; and favorable effects of lubricating and cooling as well as remarkable benefits of energy saving, emission reduction and environment protection can be achieved.

Description

technical field [0001] The invention belongs to the technical field of metal processing, and in particular relates to an aluminum alloy quasi-dry cutting microemulsion and a preparation method thereof. Background technique [0002] The traditional aluminum alloy 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 operators. of good health. Today, when energy conservation, emission reduction, environmental protection, and green production are advocated, a new aluminum alloy cutting process is urgently needed. Quasi-dry cutting and microemulsion technology is a new green aluminum alloy processing technology developed in recent years. It is to use a quasi-dry lubrication system to spray microemulsion with excellent extreme pressure, w...
