Problems solved by technology

[0006] Due to the low volume resistivity and self-ignition point of phosphate ester base oils currently on the market, they cannot meet the needs of the power industry
Industrial treatment of phosphate base oils has the problems of high energy consumption, serious pollution, and high cost. The present invention proposes to use magnesium aluminum hydrotalcite to adsorb and treat phosphate base oils. The purpose is to reduce the energy consumption and cost of phosphate base oil treatment. The easy-to-operate method removes impurities in the phosphate base oil, improves the purity, and then improves the volume resistivity and self-ignition point of the phosphate base oil

Abstract

The invention discloses a method for improving the performance of phosphate fire-resistant hydraulic oil. The method comprises the following steps: adding magnesium-aluminum hydrotalcite into phosphate base oil, carrying out stirring and adsorbing for 0.5-10 hours at a temperature of 70-200 DEG C, and then carrying out filtering and separating to obtain magnesium-aluminum hydrotalcite and improved phosphate base oil, wherein a mass ratio of the magnesium-aluminum hydrotalcite to the phosphate base oil is controlled to be (0.5-20): 100; and sequentially adding a viscosity index improver, an antioxidant, an anticorrosive agent, an acid capturing agent, an anti-foaming agent and a dye into the improved phosphate base oil, and conducting uniform mixing to obtain the phosphate fire-resistant hydraulic oil, wherein the magnesium-aluminum hydrotalcite can be recycled after being washed, filtered, dried, roasted and regenerated. According to the invention, the magnesium-aluminum hydrotalcite is used for treating the phosphate base oil, so the volume resistivity and the spontaneous ignition point of the phosphate fire-resistant hydraulic oil can be remarkably improved; and the method is simple to operate and easy to implement. In addition, the hydrotalcite can be recycled after being filtered, roasted and regenerated, so good economic benefits are achieved.

Description

Technical field [0001] The present invention belongs to the technical field of synthesis lubricants, and is specifically a method of improving phosphate anti-combustion hydraulic resistance. Background technique [0002] Phosphate anti-ignifier is an artificial synthetic lubricating oil, which mainly includes three types of trialkyl phosphate, triaryl phosphate, and alkyl aryl phosphate. Among them, triaryl phosphates have high viscosity and adhesive temperature performance compared to the same relative molecular mass, which is used to do industrial antichang pressure. In addition, phosphate anti-combustion hydraulic oil has good antibiotic resistance and excellent abrasion resistance, there is an irreplaceable position in electric power, military, aircraft hydraulic system, and near high temperature and high pressure hydraulic systems near high temperature heat and open flames. [0003] With the rapid development of the electric industry, the large-capacity, high-parameters of s...
