Embodiment 1
[0030] Example 1: Utilizing waste lubricating oil to prepare regenerated base oil
[0031] The first waste No. 32 anti-wear hydraulic oil (L-HM32) has a yellowish-brown color, becomes turbid with water, and has obvious sour odor after oxidation. Treated by the following process:
[0032] Step A, preparation of chemical solution: preparation containing NaOH mass concentration is 3%, NaOH 2 SO 3 Mass concentration 5%, CH 3 CH 2 OH mass concentration of 5% aqueous solution.
[0033] Step B, after the waste lubricating oil to be treated is adsorbed and filtered through a mineral fiber filter, material a is obtained;
[0034] Step C, pumping the material a into a refining tank, stirring, and heating the material a at the same time;
[0035] Step D, fully reacting the material a and the chemical solution in the refining tank; the specific steps of the reaction include: ① When the temperature of the refining tank rises to 60-70 ° C, the chemical solution prepared in the step A T...
Embodiment 2
[0045] Example 2 Preparation of nano new metal processing oil
[0046] Step 1, pump the regenerated base oil prepared in Example 1 into a vacuum air conditioner and kettle, start stirring, start the vacuum system, and heat the regenerated base oil at the same time;
[0047] Step 2: Fully mix the regenerated base oil with the nano-extreme pressure anti-wear agent, and disperse evenly; the specific reaction steps include: ①Heating the regenerated base oil in the vacuum reactor at a stirring speed of 90 rpm to 60- Dehydration, degassing, deodorization and deodorization at 70°C and vacuum degree ≥ 0.09Mpa for about 0.5 hours; Pump in the required nano-extreme pressure anti-wear agent; ③Keep the oil temperature in the vacuum reactor at 60-70°C, the stirring speed at 90 rpm, and the vacuum degree ≥ 0.09Mpa for 1 hour to obtain the crude product of nano-new metal processing oil ;
[0048] Step 3: After the crude product of the nano new metal processing oil obtained in the above ste...

Abstract
The invention discloses a preparation method of nanometer novel metal processing oil. The preparation method comprises the following steps: firstly, pumping regenerated base oil into a vacuum blending kettle, starting stirring and starting a vacuum system for heating the regenerated base oil; secondly, fully mixing and evenly distributing the regenerated base oil and a nanometer extreme pressure anti-wear agent to obtain a nanometer novel metal processing oil crude product; and thirdly, after indicators of the nanometer novel metal processing oil crude product obtained in the step 2 are qualified by detection, filtering the nanometer novel metal processing oil crude product and canning to obtain the finished product, namely, nanometer novel metal processing oil. The product is odorless and non-toxic, has favorable pressure anti-wear property and heat stability and no corrosion to copper, aluminum and alloys thereof and is free of such active elements as sulfur, phosphorus and chlorine. The nanometer novel metal processing oil can be used for multiple processing methods such as cutting, forging, rolling, extruding, drawing and stamping of materials such as cast iron, carbon steel, alloy steel, stainless steel, hard alloy steel, copper, aluminum and copper-aluminum alloy.
Description
technical field [0001] The invention relates to the field of metal processing oil, in particular to a novel nano metal processing oil and a preparation method thereof. Background technique [0002] Metal processing is a branch of mechanical engineering that manufactures parts, machines and components through forming, machining, welding, casting processes, changing the shape of metal blanks or removing excess metal through plastic deformation. The former process is the plastic deformation of the blank, and the latter process is mainly the removal or cutting of excess metal. These processes are accordingly divided into chipless forming and chip forming or chipless machining and machining. Metal chip forming is the metal cutting process, such as turning, milling, drawing, drilling, cutting, grinding, polishing and electro-erosion processing, etc., all of which are processed by a certain tool or grinding at a certain speed and with sufficient force , remove excess metal in the...
