Problems solved by technology

The base oil used in traditional semi-synthetic cutting fluids is a type of paraffinic base oil or naphthenic base oil. Naphthyl base oil is easy to emulsify and easy to blend, but its resources are scarce, expensive, and sources are limited; With the continuous upgrading of major refineries and the wide application of deep hydrogenation process, the supply of Class I base oil is gradually decreasing
Therefore, it is one of the choices to use the second-class base oil as the base oil of the semi-synthetic cutting fluid. However, the second-class base oil is difficult to be emulsified and blended into a stable product due to its deep refining degree and high aniline point.

Abstract

The invention discloses a semisynthetic cutting fluid adopting type-II two types of hydrogenated base oil. The semisynthetic cutting fluid is prepared from, by weight, 30%-40% of base oil, 5%-15% of polarity modifier, 10%-20% of emulsifier, 5%-15% of pH buffering agent, 2%-5% of rust inhibitor, 1%-5% of coupling agent, 2%-3% of bactericide, 0.1%-0.5% of fungicide and 25% of deionized water. The semisynthetic cutting fluid adopts the type-II hydrogenated base oil and is excellent in biological stability and low in usage loss.

Description

technical field [0001] The present invention relates to semi-synthetic cutting fluids using Class II hydrogenated base oils. Background technique [0002] Cutting fluid is an indispensable cooling and lubricating auxiliary medium in metal processing, which can effectively improve processing efficiency and precision and prolong tool life. Semi-synthetic cutting fluid has both the lubricating performance of emulsion and the long-life characteristics of full synthesis, and has been widely used in most working conditions. The base oil used in traditional semi-synthetic cutting fluids is a type of paraffinic base oil or naphthenic base oil. Naphthyl base oil is easy to emulsify and easy to blend, but its resources are scarce, expensive, and sources are limited; With the continuous upgrading of major refineries and the wide application of deep hydrogenation process, the supply of Class I base oil is gradually decreasing. Therefore, the use of Group II base oil as the base oil of...
