Problems solved by technology

Aircraft anti-icing fluid needs to be completely blown off after the aircraft passes through the troposphere, so alcohol-based anti-icing fluid for aircraft has low adhesion
Obviously, the anti-icing fluid used in aircraft is not suitable for anti-icing of railway rolling stock because of the different use environments.

Abstract

The invention provides a locomotive vehicle deicing fluid. The locomotive vehicle deicing fluid comprises, by weight, 30-70 parts of water, 30-70 parts of freezing point depressant, 0.01-5 parts of thickener, 0.01-1 part of surface active agent and 0.01-1 part of corrosion inhibitor. The freezing point depressant is one or more of dihydric alcohol and polyhydric alcohols mixed in any proportion. The thickener is one or more of silicon dioxide gel, cellulose, unsaturated hydroxy acid and magnesium lithium silicate mixed in any proportion. The surface active agent is one or more of fatty glyceride surface active agent, polyoxyethylene surface active agent, sulfoacid compound surface active agent and polyhydric alcohol surface active agent mixed in any proportion. The corrosion inhibitor is one or more of nitrogen, or sulfur or hydroxy organic corrosion inhibitor, carbonate corrosion inhibitor and phosphate corrosion inhibitor mixed in any proportion. The locomotive vehicle deicing fluid has excellent adhesion property, and freezing of the bogie portion on the bottom of a vehicle in a severe cold area can be prevented.

Description

technical field [0001] The invention belongs to the technical field of railway transportation and antifreeze and snow removal, and in particular relates to an antiicing liquid applied to railway rolling stock. Background technique [0002] As the railway extends to Tibet, Qinghai and other alpine regions, railway vehicles will inevitably face the problem of ice and snow during winter operation. If the locomotives and vehicles operating in snowy areas for a long time do not take special treatment, the flying snowflakes will penetrate into the gaps of mechanical components such as bogies and electrical connectors, and will solidify and expand again, which will hinder the normal operation of these components; brake shoes and brake pads After the ice and snow are attached, the braking efficiency will be reduced at the beginning of braking, which will affect the reliability of train braking; if the doors are frozen by snow water, it will affect the boarding and landing time of th...
