Titanium coating material applied to heat exchanger fin of air conditioner and preparation method thereof

Abstract

The invention provides a titanium coating material applied to a heat exchanger fin of an air conditioner and a preparation method thereof. The main compositions of the titanium coating material are nano titanium dioxide, nano silver nitrate, polymer dispersants and binding agents. The preparation method comprises the following steps of: adding a certain ratio of polymer dispersants into absolute ethyl alcohol, then adding the binding agents, stirring fully and adding the nano silver nitrate and the nano titanium dioxide of which the surface is subject to both organic and inorganic composite coating processing into the stirred absolute ethyl alcohol solution, and dispersing by using the high-speed dispersants. By the invention, the defects of the prior art are overcome; ethanol is used as the solvent, so that the nano composite material has better spreadability and stronger adhesive power on an aluminum foil of the air conditioner; organic dirt can be effectively decomposed by the nanotitanium dioxide, and the nano titanium dioxide can play the hydrophilic role, so that the breeding of bacteria on the fin is prevented, and the heat exchange performance of the heat exchanger is guaranteed at the same time.

Description

technical field [0001] The invention relates to the field of air conditioners, in particular to a titanium gold coating material on fins of air conditioner heat exchangers and a preparation method thereof. Background technique [0002] After the air conditioner has been used for a period of time, a large amount of dust and bacteria will grow on the surface of the fins of the heat exchanger (including the evaporator and condenser), which not only affects the heat exchange effect of the heat exchanger, but also smells bad and affects The reason for the above situation is that most of the existing air-conditioning heat exchanger fins use ordinary hydrophilic aluminum foil, which only has a certain degree of hydrophilicity and does not have the functions of sterilization and self-cleaning. Function, and after a certain period of use of ordinary hydrophilic aluminum foil, because its surface is covered with dirt and dust, the hydrophilicity will decrease, and the accumulated wate...
