Description
Technical Field
The application belongs to the technical field of high ignition point polyethers, and particularly relates to a high ignition point polyether, a preparation method and application thereof.
Background
The polyether is a polymer prepared by taking ethylene oxide, propylene oxide, butylene oxide and the like as raw materials and carrying out polymerization reaction with different initiators under the action of a catalyst.
The hydraulic technology is a key technology for realizing modern transmission and control, and hydraulic oil (liquid) is an important component of the hydraulic technology and plays roles of energy transmission, system lubrication, corrosion prevention, rust prevention, cooling and the like in a hydraulic system. The polyether is applied to the water-glycol flame-resistant hydraulic fluid as a thickener of the flame-resistant hydraulic fluid, and plays a decisive role in performances such as viscosity, viscosity-temperature characteristic, inverse melting point, defoaming property and the like of the hydraulic fluid. The polyether can also be used as the main component of the flame-retardant hydraulic fluid to be applied to the whole oil formula.
The flame-resistant hydraulic fluid is mainly applied to hydraulic systems which are easy to access high-temperature open fire in industries such as metallurgy, mining, power plants, machining and the like, and when a high-pressure hydraulic pipeline is leaked or broken, oil is atomized and can be sprayed far. In this case, an open flame, or a very hot surface, may cause a fire. Because of the flowing and diffusing property of the oil, the fire is increased, and the danger is increased. The fire-resistant hydraulic fluid can avoid fire accidents caused by leakage of hydraulic oil using traditional mineral oil. In addition, some hydraulic systems requiring high safety factors for aviation, aerospace and naval vessels must also use fire-resistant hydraulic oil. Currently, the main types of fire-resistant hydraulic oils include: phosphate ester type, fatty acid ester type, synthetic type, water-glycol type, emulsion, high water-based liquid, and the like.
The phosphate flame-retardant hydraulic oil is suitable for a high-pressure hydraulic system with the temperature range of-20-150 ℃ and the pressure of less than 40 MPa. The phosphate has the most outstanding flame resistance, and the self-ignition point is up to 550 ℃ or more. The flame does not spread even if it catches fire at high temperature. The hydraulic system is suitable for a hydraulic system with high temperature and open fire nearby. Its disadvantages are toxicity to humans and the price of it is much higher than other classes of fire-resistant hydraulic oil.
Fatty acid esters are technically feasible to replace mineral oils for hydraulic systems with fire-resistant requirements, but fatty acid ester fire-resistant hydraulic fluids also have significant disadvantages: the fatty acid ester hydraulic fluid is easily hydrolyzed in the presence of water, and carboxylic acid generated by the hydrolysis causes metal corrosion, in which case oil change is necessary.
The water-glycol flame-retardant hydraulic oil has the largest application proportion at present, and is suitable for a hydraulic system with the temperature range of-30-60 ℃ and the pressure of less than 20 MPa. The disadvantage of water-glycol is the poor lubrication properties, and as hydraulic devices develop towards high temperature, high pressure and high efficiency, the lubrication properties and lifetime of the fire-resistant hydraulic oils are very important. The water-glycol has micro toxicity and general environmental protection performance.
The emulsion has low price and is suitable for hydraulic systems with the temperature range of 5-55 ℃ and the pressure of less than 14 MPa. Under the working condition of high temperature and high pressure, the emulsion has poor stability, is easy to decompose, and has serious pollution to the environment by waste oil. The high water-based HFA hydraulic fluid has the advantages of good flame resistance, high heat transfer efficiency, low price and the like, but also has the defects of poor lubricity, easy corrosion, leakage and the like.
Polyether is used as synthetic flame-resistant hydraulic fluid with many excellent properties, including good lubricating property, long service life, high flash point and viscosity index, low volatility and pour point, little effect on metal and rubber, and the oxidation products generated during high temperature use are completely dissolved in the rest liquid or completely volatilized, no deposit is left in the equipment, and especially the properties of polyether products can be flexibly adjusted by using variable factors in polyether molecules to meet various different use requirements. These characteristics of polyethers open up a wide prospect for their practical use, and polyethers have been successfully used as high temperature lubrication, flame resistant hydraulic fluids, gear oils, compressor oils, brake fluids, metal working fluids, and specialty grease base oils. Polyethers are one of the most widely used synthetic lubricants with the greatest yield. However, the existing polyether products have lower ignition points and higher potential safety hazards in use.
