Abstract

The invention relates to a low-temperature antifreezing agent comprising the following components in parts by mass: 13-16 parts of methyl silicone oil, 22-27 parts of polydimethylsiloxane, 8-12 parts of aviation kerosene, 8-12 parts of AEO-9 and 35-45 parts of water. A method for preparing the low-temperature antifreezing agent comprises the following steps: (1) mixing 8-12 parts by mass of AEO-9 with 35-45 parts by mass of water; (2) stirring the mixed solution of AEO-9 and water; (3) adding 13-16 parts by mass of methyl silicone oil, 22-27 parts of by mass of polydimethylsiloxane and 8-12 parts by mass of aviation kerosene to obtain a final mixed solution; and (4) stirring the final mixed solution to obtain a final product. The ice resistance of the antifreezing agent provided by the invention under an extremely-low temperature condition is better than that of an existing antifreezing agent product.

Description

technical field [0001] The invention belongs to the technical field of antifreeze, in particular to a low-temperature antifreeze and a preparation method thereof. Background technique [0002] Water / glycol-based antifreezes are used to remove frozen deposits. Glycols are used to lower the freezing point of the medium and, moreover, surfactants are present which reduce the surface tension of the antifreeze and thus improve the wetting of aircraft surfaces. Furthermore, antifreeze can also contain corrosion inhibitors, defoamers, dyes and flame retardant substances. Unlike pure antifreeze, antifreeze also contains thickener substances. The viscosity of these fluids thus improves the protection against refreezing, since these fluids flow off the aircraft surface very slowly only in a stationary state and are therefore able to absorb frozen deposits over a longer period of time. However, it is unavoidable that the thickeners are more or less destroyed under mechanical load. ...
