Lubricating oil for aluminum alloy sawing and preparation method of lubricating oil

Abstract

The invention discloses lubricating oil for aluminum alloy sawing and a preparation method of the lubricating oil, wherein the lubricating oil is prepared from synthetic ester, poly alpha-olefin, sulfurized fatty acid ester, phosphate, calcium alkyl sulfonate and macromolecular polyester tackifier; the mass percentage of the synthetic ester in the lubricating oil is 10-50%, the mass percentage ofthe poly alpha-olefin in the lubricating oil is 10-50%, the mass percentage of the sulfurized fatty acid ester in the lubricating oil is 1-10%, the mass percentage of the phosphate in the lubricatingoil is 1-5%, the mass percentage of the calcium alkyl sulfonate in the lubricating oil is 1-3%, and the mass percentage of the macromolecular polyester tackifier in the lubricating oil is 1-5%. At constant pressure, the synthetic ester, the poly alpha-olefin, the sulfurized fatty acid ester, the phosphate, the calcium alkyl sulfonate and the macromolecular polyester tackifier are added into a kettle to stir and heat up to 60-80 DEG C; the stirring is carried out for 30-50min till the product is mixed uniformly; and then the material is discharged, filtered and packaged. The lubricating oil ismixed with compressed air to achieve purposes of satisfying a sawing process, recycling sawdust, saving energy and protecting environment.

Description

technical field [0001] The invention relates to a kind of micro lubricating oil used for aluminum alloy sawing, which belongs to the field of organic chemistry, more precisely, relates to a kind of lubricating oil which is mixed with compressed air and acts on the sawing surface of aluminum alloy to ensure the smooth progress of the sawing process. Lubricating oil, the present invention also includes the preparation method of this lubricating oil. Background technique [0002] Aluminum alloy sawing processing is commonly used at home and abroad to use emulsion or low-viscosity pure oil processing fluid for cooling and lubrication. This method has the advantages of good cooling and economical use, but the processing efficiency is extremely low and the life of the saw blade is short. Oil has poor adhesion and is easy to be thrown out during high-speed sawing. Low-viscosity pure oil processing fluid has large oil mist and poor safety when used on site, so it is only suitable fo...

[0002] Aluminum alloy sawing processing is commonly used at home and abroad to use emulsion or low-viscosity pure oil processing fluid for cooling and lubrication. This method has the advantages of good cooling and economical use, but the processing efficiency is extremely low and the life of the saw blade is short. The oil has poor adhesion and is easy to be thrown out during high-speed sawing. The low-viscosity pure oil processing fluid has large oil mist and poor safety when used on site, so it is only suitable for low-speed sawing.

However, this type of oil cannot meet the process requirements for high-speed sawing processing. A new type of lubricant, that is, a special micro-quantity lubricant must be used for cooling and lubrication. The metal chips generated during the processing need to be recycled. Therefore, this type of oil is similar to dry type Cutting or sawing processing called less oil cutting generally adopts spraying method to spray the mixture of lubricant and air on the working surface of continuous processing. The lubricant is required to have moderate atomization ability and good extreme pressure lubricity, otherwise it cannot Taking into account its cooling and processing performance, the safety of the saw blade coolant cannot be ignored, because the lubricant atomization ability is too good, it is easy to cause fire and the consumption is large and uneconomical, and if it is too poor, it will cause uneven spraying of the lubricant and damage the saw blade. poor lubrication
