preparation example Construction

[0036] A preparation method of a long-acting micro-emulsion cutting fluid for metal processing of the present invention comprises the following steps:

[0037] Step 1: Mix 15-20% Priolube 3955, 2-3% RT45LT, 2-5% RT64LT and 1-2% EL20, and stir well;

[0038] Step 2: Mix 5~7% DGA, 2~3% AMP-95, 2~5% Guerbet acid, 5~10% L190 PLUS and 40~60% deionized water at 40~60℃ , get phase two;

[0039] Step 3: Put the phase 1 obtained in step 1 into the reaction kettle, keep the temperature between 30 and 40 ° C, start stirring, and slowly put 1-2% FS-640, 0.1-0.3% ROCIMA342, 1-3% BUSAN77 into it in turn. , 0.9-1.9% BIT20, stir for 50-70min, and then slowly inject the phase 2 obtained in step 2 into the above system, and continue stirring for 3-5h to obtain cutting fluid.

[0040] In the prior art, in order to make the metal working fluid spread evenly on the metal surface and thus ensure a good processing effect, a surfactant that can reduce the surface tension is usually added to the cut...

Embodiment 1

[0046] (1) Mix 20% Priolube 3955, 2% RT45LT, 3% RT64LT and 1% EL20, and stir well;

[0047] (2) Mix 6% DGA, 3% AMP-95, 4% Guerbet acid, 6% L190 PLUS and 51% deionized water at 50°C to obtain phase two;

[0048] (3) put the obtained phase one in (1) into the reaction kettle, keep the temperature between 30 ℃, start stirring, and slowly put 1.8% FS-640, 0.2% ROCIMA342, 1% BUSAN77, 1% BIT20 into it successively, After stirring for 60 min, slowly inject the phase two obtained in (2) into the above system, and continue stirring for 4 h to obtain the cutting fluid.

[0049] The above obtained cutting fluid stock solution is diluted to obtain a 5wt% dilution solution and a 10wt% dilution solution. The stock solution and the dilution solution are respectively tested for appearance, stability, anti-corrosion, anti-rust performance, particle size and other properties. Test method and result as figure 1 shown. from figure 1 It can be seen that the stock solution of the cutting fluid ...

Embodiment 2

[0051] (1) Mix 15% Priolube 3955, 2% RT45LT, 2% RT64LT and 2% EL20, and stir well;

[0052] (2) Mix 5% DGA, 2% AMP-95, 2% Guerbet acid, 5% L190 PLUS and 60% deionized water at 40°C to obtain phase two;

[0053] (3) put the obtained phase one in (1) into the reaction kettle, keep the temperature between 35 ℃, start stirring, and slowly put 2% FS-640, 0.1% ROCIMA342, 1% BUSAN77, 1.9% BIT20 into it successively, After stirring for 65min, slowly inject the phase two obtained in (2) into the above system, and continue stirring for 3h to obtain the cutting fluid.

[0054] To above-mentioned gained cutting fluid stoste and its dilution, obtain 5wt% diluent and 10wt% diluent, respectively carry out appearance, stability, anti-corrosion, anti-rust performance, particle size and other properties to stoste and diluent to test (test method Same as Example 1), test results are basically the same as Example 1.

Abstract

The invention discloses a long-acting microemulsion cutting fluid for metal processing and a preparation method thereof, belonging to the technical field of metal processing and protection. It includes the following components in mass percent: lubricant 15-20%, non-ionic surfactant 5-10%, alcohol amine 7-10%, bactericide 1-2%, anti-rust coupling agent 2-5%, anti-corrosion Rust agent 5-10%, cationic surfactant 1-3%, acetylenic alcohol 1-2%, deionized water 40-60%. The preparation method is as follows: (1) mix lubricant and nonionic surfactant into phase one, and stir evenly; (2) mix alcohol amine, antirust coupling agent, antirust agent and deionized water evenly to obtain phase two (3) adding acetylenic alcohol, bactericide and cationic surfactant to phase 1 obtained in (1) in sequence, and then injecting phase 2 obtained in (2), and stirring evenly to obtain cutting fluid. Adopting the technical scheme of the present invention can improve the stability of the cutting fluid, and it has more excellent lubricating, antirust, anticorrosion and other properties, and has a longer service life.

Description

technical field [0001] The invention belongs to the technical field of metal processing and protection, and more particularly relates to a long-acting micro-emulsion cutting fluid for metal processing and a preparation method thereof. Background technique [0002] Aluminum alloy is a non-ferrous light metal with small specific gravity, low hardness, high specific strength, good plasticity, easy processing and forming, good corrosion resistance in atmospheric environment, and good physical and mechanical properties. In the process of processing, transportation and storage of aluminum alloy workpieces, the surface often has corrosion, molding sand, dust, oil and other contaminants left in the mold. The surface must be cleaned before assembly. Sand blasting and shot blasting belong to the mechanical treatment process in surface treatment. The impact of sand blasting and shot blasting on the workpiece is as follows: removing various pollutants on the surface of the workpiece; r...
