Novel cryogenic lubrication cutting fluid

Abstract

The invention discloses a novel cryogenic lubrication cutting fluid, which is prepared from the following raw materials by weight: 2.5-6.5 parts of 2-amino-2-methyl-1- propyl alcohol, 3.5-8.5 parts of vulcanized oil, 25-55 parts of kerosene, 10-15 parts of deionized water, 5-10 parts of glycerol, 1.5-2.2 parts of benzo isothiazolone and 0.8-2.5 parts of styrene maleic anhydride. Compared with the existing cutting fluid, the lubrication cutting fluid provided by the invention has excellent lubricating extreme pressure properties, and a 10% water solution extreme pressure test shows that the PB value can reach 70 kgf, which fully meets the lubrication requirements for synthesizing cutting fluid. The cutting fluid has excellent corrosion and rust-resisting properties, is applicable to processing of a plurality of materials such as cast iron, alloy steel, stainless steel and aluminum alloy. In addition, the cutting fluid has the advantages of good biological stability, long service life, difficulty in stinking, good cooling and good cleaning performance, cleaning workpiece after machining, good environment-friendliness and safety for usage.

Description

Technical field [0001] The present invention involves a new type of low -temperature lubricant, which belongs to the field of industrial chemical industry. Background technique [0002] Because the full synthetic metal machining solution does not contain mineral oil, it usually uses polyether to increase the lubrication performance of the processing solution. In view of its limited lubrication pole pressure, the full synthetic cutting solution is mainly used in grinding processing and some of the requirements for lubrication extreme pressure.High material and craftsmanship.For harsh and difficult processing materials and processes (materials such as stainless steel, high -hard alloy steel, etc.; Craftsmanship such as attack wire, deep hole drill, hinge, etc.) must be usedUse cutting oil to process.However, the existing cutting fluid has poor corrosion and rust resistance, short use cycle, easy to stink, and the cleanliness of the workpiece after processing is very low.
