Abstract

The present invention discloses one kind of extreme pressure emulsified oil for metal cutting and its preparation process. The extreme pressure emulsified oil consists of No. engine oil 52-56 wt%, zinc naphthenate 6-9 wt%, petroleum sodium sulfonate 12-16 wt%, oleic acid 2-3 wt%, triethanolamine 4-6 wt% and high viscosity paraffin chloride 12-16 wt%. It is prepared through heating and mixing. Before being used, the extreme pressure emulsified oil is diluted. The present invention has excellent antirust property, lubricating property, cooling property and cleaning property, and may be used in turning, milling, planing, grinding and other machining process. It has no toxicity, no irritation and low cost.

Description

technical field [0001] The invention relates to the technical field of lubricants, in particular to an extreme pressure emulsified oil for metal cutting and a manufacturing method thereof. Background technique [0002] In the machining industry, with the continuous improvement of processing difficulty and processing accuracy requirements, the requirements for cutting tools and cutting fluids are also increasing. The cutting fluid currently used has poor working stability, long service life, poor rust resistance and permeability, odor, and is easy to deteriorate, while emulsified oil with relatively good performance has high cost and high price, so Cutting fluid with stable performance and low cost is a demand development direction in the market. Contents of the invention [0003] The object of the present invention is to provide a kind of extreme pressure emulsified oil for metal cutting with high lubricity and excellent rust resistance and its manufacturing method. With...
