Abstract
The invention relates to an ester type fire-resistant hydraulic fluid. The hydraulic fluid comprises the following raw materials by weight percent: 95-99% of base oil, 1.0-5.0% of diphenol propane, 0.005% of dimethylsilicone fluid or dimethylsilicone grease, 0.05% of tricresyl phosphate, 0.1% of benzotriazole, 100 parts per million (PPM) demulsifying agent T1001 or LZ5957 and 0.2-0.3% of triazole derivative, thiadiazole derivative, N-salicylidene ethylamine, N, N'-bis(salicylidene)ethylenediamine, N, N'-bis(salicylidene)propylene diamine or ethylenediamine tetraacetic acid. A preparation method of the ester type fire-resistant hydraulic fluid comprises the following steps of sufficiently and evenly stirring various materials at room temperature according to a formula, and then filtering. The ester type fire-resistant hydraulic fluid has the beneficial effects that the high temperature use performance of the product is greatly improved, the service life of a hydraulic system and the oil changing period of oils are prolonged, and the ester type fire-resistant hydraulic fluid has a good flame-retardant effect and is safe to use. The preparation method has the advantages that operation is convenient, technology and equipment are simple, energy consumption is low, cost is low, and the like.
Description
technical field [0001] The invention relates to a hydraulic oil and a preparation method thereof, in particular to an ester type flame retardant hydraulic oil and a preparation method thereof. Background technique [0002] Hydraulic oil is the hydraulic medium used in the hydraulic system that utilizes the pressure energy of the liquid. It plays the role of energy transmission, system lubrication, anti-corrosion, anti-rust, cooling and so on in the hydraulic system. For hydraulic oil, it should first meet the requirements of the hydraulic device on the viscosity of the liquid at the working temperature and the starting temperature. Since the viscosity change of the oil is directly related to the hydraulic action, transmission efficiency and transmission accuracy, the viscosity-temperature performance of the oil and the Shear stability should meet the various needs raised by different uses. There are many types of hydraulic oil, and the classification methods are different. ...
