Abstract

The invention relates to aviation cooling liquid, in particular to environment-friendly organic aviation cooling liquid, and further discloses a preparation method of the environment-friendly organicaviation cooling liquid. The environment-friendly organic aviation cooling liquid comprises benzoic acid, isocaprylic acid, sebacic acid, cinnamic acid, a benzotriazole compound, an antifoaming agent,a bactericide, a pH value regulator, ethylene glycol and deionized water. Based on organic synergistic cooperation of the components, the cooling liquid has good corrosion inhibition performance on different metals, can effectively prevent corrosion of all metal and non-metal materials in contact with the interior of an aviation cooling system, has outstanding anti-foaming performance and rubbercompatibility, and completely meets the requirements of GJB 6100 standards; and the whole cooling liquid component does not contain amine substances and inorganic salts such as acid salts, nitrates, nitrites and acid salts, so that the cooling liquid is a real environment-friendly aviation cooling liquid, is beneficial to environmental protection performance requirements, and can meet the use requirements of the aviation cooling system.

Description

technical field [0001] The invention relates to an aviation cooling liquid, in particular to an environment-friendly organic aviation cooling liquid, and further discloses a preparation method thereof. Background technique [0002] At present, the coolant used in the liquid cooling system can be divided into several types from the chemical composition of the base liquid: water, water-ethylene glycol, water-propylene glycol, anhydrous propylene glycol, PAO synthetic hydrocarbon, fluorocarbon, etc.; from the function can be divided into It is: ordinary conductivity type, low conductivity type, radiation protection type; from the preservative system, it can be divided into: organic acid type, inorganic salt type and organic acid-inorganic salt mixed type; from the application, it can be divided into military and civilian use or ground and aviation . Among them, the water-glycol ordinary conductive coolant is the most widely used and widely used. [0003] The development of co...
