Problems solved by technology

In the formulas of the above-mentioned patents, since each formula is a conventional choice, and no targeted ingredients are added, it cannot effectively reduce the adhesion of ice on the surface of the object, and does not make the deicing and anti-icing fluid have a good performance. The behavior of viscosity and low temperature shear rheology also has a very limited role in improving the anti-icing time, and only meets the time requirements of type II fluids

Abstract

The invention relates to a deicing and anti-icing fluid, particularly a non-Newtonian fuselage deicing and anti-icing fluid and a preparation method thereof. The non-Newtonian fuselage deicing and anti-icing fluid can reduce adhesion of ice on the object surface to eliminate and prevent icing on the aircraft fuselage surface, and has superlong anti-icing retention time. The non-Newtonian fuselage deicing and anti-icing fluid comprises the following components in parts by mass: 40-60 parts of freezing-point depressant, 0.05-1.2 parts of rheologic modifier, 0.01-0.3 part of anti-icing compounding agent, 0.01-3 parts of pH regulator, 0.01-3 parts of corrosion inhibitor, 0.01-0.5 part of staining agent and 40-60 parts of deionized water. The invention is based on the low-temperature rheologic research, especially aims at the low-temperature operating environment and characteristics of the deicing and anti-icing fluid, and determines the distribution and arrangement of the main chain and branch chain of the rheologic modifier as well as the preparation and acquisition method of the low-temperature conformation. By combining the anti-icing compounding agent, corrosion inhibitor and other assistants in the formula, the prepared deicing and anti-icing fluid has the characteristics of excellent shearing restorability, excellent ice adhesion inhibition capacity at 0 to -20 DEG C, and long anti-icing time.

Description

technical field [0001] The invention relates to a liquid for deicing and anti-icing. Specifically, it relates to a non-Newtonian airframe deicing and anti-icing fluid capable of reducing ice adhesion on the surface of objects, eliminating and preventing ice formation on the surface of an aircraft fuselage, and having super long anti-icing holding time and a preparation method thereof. Background technique [0002] In icy weather conditions, the surface of an aircraft staying on the ground can easily form pollutants such as ice, snow, and frost. These pollutants will not only increase the weight and resistance of the aircraft, but also cause the flight attitude of the aircraft to take off to be difficult to control, and in severe cases, cause air crashes. The most effective way to prevent ground aircraft from icing is to use aircraft deicing and anti-icing fluids. The deicing and anti-icing fluid melts the pollutants such as ice, snow and frost that have accumulated on the ...
