Detailed Description

The flame-resistant hydraulic fluid of the invention will not burn in most cases, and even if the mist-like high-pressure fluid sprayed from the hose, pipe or joint is sprayed to the flame, molten metal surface or other hot body surface in case of accidental leakage of the hydraulic system, the flame will not be generated. Even if the flame-retardant agent is sprayed to a human body, the flame-retardant agent can not be burnt and can not cause harm to the human body. Even if the leaked liquid continuously flows to the surface of the molten metal or other hot bodies, the liquid does not immediately catch fire, but only generates fire flames within the area range directly contacted with the hot bodies after the moisture is evaporated, and the fire flames do not extend to the periphery. Because of the special chemical components, the combustion heat energy of the hydraulic fluid is much lower than that of the mineral oil, so the flame temperature is very low, and the hydraulic fluid is easy to extinguish. Wherein, in PAG, SDN-15 and SDN-45 have the following technical indexes:
| V4℃(mm2/s) | cloud Point (1% Water, DEG C) | Appearance (20 ℃ C.) | |

The hydraulic fluids of the above examples were tested for flash point and ignition point according to ISO2592, for wear scar diameter according to GB/T3143, and for maximum non-seizing load according to ASTM D4152, the larger the maximum non-seizing load, the smaller the wear scar diameter, the better the wear resistance, and the results are shown in Table 1
Finally, the above embodiments are only for illustrating the technical solutions of the present invention and not for limiting, although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered in the claims of the present invention.
