Problems solved by technology

However, due to the use of a cooling method in which water vaporization takes away a large amount of heat, there will be rusting when processing ferrous metals. Use the special microlubricant produced by the oil-water-gas three-phase microlubrication system such as CN104031732A and its preparation method There are two problems when lubricating and cooling: 1. Adding agent B to the water tank is troublesome, and it is often discarded by workers in the actual production process; 2. Some solids of agent B may not be dissolved during use and are added to the water tank, resulting in energy saving Problems such as nozzle clogging

Abstract

The invention relates to a boric acid phosphate fatty ester, which is characterized in that it is prepared from the following components in weight percent: 80-90% of fatty alcohol; 5-10% of phosphoric acid; and 5-10% of boric acid. The present invention also provides a micro-lubricating oil prepared from the ester, which is characterized in that it is prepared from the following components in weight percent: boric acid phosphate fatty acid ester 10-20%; synthetic ester 70-80%; polyester 5-10% %; Acyl sarcosine or its sodium salt 5-10%. The micro-quantity lubricating oil is used in conjunction with a micro-lubrication device, and the usage amount can be reduced to less than 5% of the original, achieving good lubricating, cooling and anti-rust effects, with remarkable benefits in energy saving, emission reduction and environmental protection.

Description

technical field [0001] The invention belongs to the technical field of lubrication, and in particular relates to a fatty boric acid phosphate ester, a preparation method thereof, and a micro-quantity lubricating oil prepared from the ester. Background technique [0002] The traditional metal cutting process uses mineral oil or vegetable oil or cutting fluid for a large amount of shower lubrication and cooling. 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. Healthy body. Today, when energy conservation, emission reduction, environmental protection, and green production are advocated, a new metal cutting process is urgently needed. [0003] Micro-quantity lubrication technology is a new metal green processing technology developed in recent years. It is to use a micro-quantity lubrication system to spray a micro-quantity lu...
