Bio-based alcohol airplane ice removal and prevention liquid and preparation method thereof

Abstract

The invention relates to a liquid for removal and prevention of ice on the outer surface of an airplane, and especially relates to a bio-based alcohol airplane ice removal and prevention liquid for removing ice, snow and frost staying on the surface of an airplane and a preparation method thereof. The bio-based alcohol airplane ice removal and prevention liquid comprises, by mass, 40-90 parts of at least one bio-based polyol, 0.01-1 part of at least one organic acid, 0.01-1 part of at least one organic amine, 0.01-0.3 parts of a metal organic composite salt, 0.03-0.2 parts of a surfactant and 10-60 parts of deionized water. Through use of bio-based alcohol as a main raw material of a freezing point reduction agent, the problems caused by petrochemical-based alcohol raw material performance difference are solved. The preparation method of the liquid for removal and prevention of ice on the outer surface of an airplane is a novel technology in the field of energy saving and emission reduction. The bio-based alcohol airplane ice removal and prevention liquid can satisfy high material compatibility requirements, has effects of energy saving and emission reduction, substantially reduces a carbon dioxide discharge capacity, is conducive to resource cycle usage and has the characteristics of safety, environmental friendliness and low carbon.

Description

technical field [0001] The invention relates to a liquid for deicing and anti-icing on the outer surface of an aircraft, in particular to a bio-based alcohol aircraft de-icing and anti-icing liquid for removing ice, snow and frost remaining on the surface of an aircraft on the ground and its preparation method. Background technique [0002] In icy weather conditions, the outer surface of the aircraft staying on the ground is very easy to adhere to pollutants such as ice, snow and frost. These pollutants have seriously affected the normal flight and safety of the aircraft, especially making it difficult to control the flight attitude of the aircraft when the aircraft takes off. The most effective deicing and anti-icing method in general at present is to adopt aircraft deicing and anti-icing liquid. The aircraft deicing and anti-icing fluid melts the pollutants such as ice, snow and frost that have accumulated on the surface of the aircraft, and further prevents the accumula...

Problems solved by technology

[0006] In view of the problems that the existing ordinary aircraft deicing and anti-icing fluids use non-renewable raw materials, contain harmful substances to the environment, and have poor environmental protection and safety performance, the deicing and anti-icing fluids with bio-based alcohols as freezing point depressants have the disadvantages of deicing and anti-icing Poor performance, low thermal storage stability, and stability to metal materials cannot meet the requirements of aircraft deicing and anti-icing fluids. Now a bio-based alcohol aircraft deicing and anti-icing fluid that can solve the above problems and its preparation are proposed method
