Problems solved by technology

Micro-quantity lubricating oils developed with synthetic esters or Guerbet alcohols as base oils can basically achieve a relatively ideal lubricating effect, but during use, due to the excessive frictional heat generated at the moment of contact between the tool and the material, some ester molecules Decomposition and / or evaporation of the Guerbet alcohol, resulting in an unpleasant odor that impairs practical use

Abstract

The invention provides an environment-refreshing lubricating oil composition which is characterized by being prepared from terpilenol, malic acid and phosphorus pentoxide, and the molar ratio of terpilenol to malic acid is 2-2.1: 1. The weight of phosphorus pentoxide is 0.5-1% of the total weight of terpilenol and malic acid. The environment-refreshing lubricating oil composition prepared by adopting the preparation method is good in lubricating property and biodegradable, a small amount of decomposer terpilenol / alkene can refresh the environment and eliminate peculiar smell in the processing process, and the environment-refreshing lubricating oil composition also has certain extreme-pressure anti-wear property. The invention also provides environment-refreshing lubricating oil containing the environment-refreshing lubricating oil composition. The environment-refreshing lubricating oil is prepared from the following components in percentage by weight: 10-20% of the environment-refreshing lubricating oil composition; 65-75% of trimethylolpropane trioleate; and 10-20% of castor oil borate diethanolamine salt.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a fresh environment trace lubricating oil and a preparation method thereof. Background technique [0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication. The amount of lubricant used is large, which not only wastes resources, but also causes huge pollution to the processing site and the environment, and also seriously affects the health of the operators. . [0003] In order to solve these problems, some progress has been made in the research of micro-quantity lubrication technology recently. The micro-quantity lubrication technology solves the above problems such as large amount of lubricant used and serious pollution. At the same time, in order to make the micro-quantity lubricant used have relatively strong extreme pressure and anti-wear Sex and lubricity, excessive use of sulfur...
