Novel flame-retardant type synthetic hydraulic oil for coal mine

Abstract

The invention discloses novel flame-retardant type synthetic hydraulic oil for a coal mine. The novel flame-retardant type synthetic hydraulic oil is prepared from the following raw materials in parts by weight: 280 to 285 parts of industrial oleic acid, 12.6 to 13 parts of iodine, 72 to 74 parts of acrylic acid, 134 to 135 parts of TMP (Trimethylolpropane), 15 to 16 parts of toluenesulfonic acid, 15 to 17 parts of nano boron carbide particles, 0.8 to 1 part of span 80, 2 to 3 parts of CMC (Carboxy Methylated Cellulose) sodium, 30 to 32 parts of deionized water, 3.2 to 3.5 parts of hydroxyethyl imidazolidine, 10 to 12 parts of polymethacrylate, 3.5 to 4 parts of zinc dialkyl dithiophosphate, 0.08 to 0.1 part of benzotriazole, 0.07 to 0.08 part of barium dinonyl naphthalene sulfonate, 3 to 4 parts of tricresyl phosphate, 2 to 3 parts of DMMP (Di-methyl Methyl Phosphonate) and 2.5 to 3 parts of lead naphthenate. The novel flame-retardant type synthetic hydraulic oil prepared by the invention is good in rust resistance, corrosion resistance and flame retardancy and is very suitable for being used by hydraulic equipment of a coal mine system.

Description

technical field [0001] The invention relates to the field of hydraulic technology, in particular to a novel flame retardant synthetic hydraulic oil for coal mines. Background technique [0002] In recent years, with the development and improvement of hydraulic system design and manufacturing technology, hydraulic technology has been widely used in the new generation of mechanical equipment. The variability of the working environment of hydraulic machinery brings great challenges to hydraulic oil: hydraulic oil must withstand the test of high pressure, high temperature, temperature changes, and harsh environments. It needs to have excellent viscosity-temperature performance and high load-bearing capacity to ensure mechanical However, the existing anti-wear hydraulic oil is difficult to fully meet the complex and changeable working conditions of the hydraulic system. The widely used anti-wear hydraulic oil has a low viscosity index and poor viscosity-temperature performance. ...

However, with the strengthening of people's awareness of environmental protection and the increasingly stringent environmental regulations, the development and use of biodegradable lubricating oils has attracted more and more attention. Most hydraulic base oils have poor biodegradability and are biodegradable lubricating materials.
