Description
Technical field
The present invention relates to a kind of water base flame retardant hydraulic fluid composition, more precisely is a kind of water-glycol fire-retardand hydraulic fluid enriched material and by the formulated hydraulic composition of this enriched material.
Technical background
Hydraulic technique is one of gordian technique that realizes modern transmission and control, compares with other transmissions, and hydrostatic transmission has compact construction, be quick on the draw, easily realize characteristics such as operation automation.Hydraulic efficiency oil (liquid) is an important component part of hydraulic technique, and it plays effects such as transmission ofenergy, system are lubricated, anticorrosion, antirust, cooling in hydraulic efficiency system.At present, along with improving constantly of introducing equipment and domestic mechanical means manufacture level, the operating mode of hydraulic efficiency installation is harsh day by day, to hydraulic efficiency oil (liquid) demands for higher performance, is embodied in following several respects:
(1) service temperature is higher, requires oil product to have good oxidative stability and heat-resistant quality;
(2) owing to used the fine filtering element, require oil product to have filterableness preferably;
(3) the fuel tank size reduces, and has increased the oil product cycle index, requires hydraulic efficiency oil to have higher thermostability;
(4) require to use the better multistage hydraulic oil of viscosity temperature characteristic (liquid);
(5) require hydraulic efficiency oil biodegradable, compliance with environmental protection requirements.
Water-in-oil-type and oil-in-water-type fire resistant hydraulic oil (liquid) are cheap, are applicable to the hydraulic efficiency system that temperature and pressure is all lower, and the problem of the two existence is that its waste oil liquid environmental pollution is serious than other fire resistant hydraulic oil.Water-glycol fire-retardand hydraulic fluid accounts for fire resistant hydraulic oil ratio maximum, and applying pressure reaches as high as 35MPa, and along with hydraulic efficiency plant develops towards high temperature, high pressure and high-level efficiency direction, the lubricity and the life-span of improving the water-ethylene glycol fire resistant hydraulic oil seem extremely important.
In order to satisfy the new demand that hydraulic efficiency installation constantly proposes, hydraulic efficiency oil (liquid) prescription and additive technology had been obtained many new progresses both at home and abroad in recent years.
