Problems solved by technology

At present, the distance between the fins of the heat exchanger in the air conditioner is getting smaller and smaller. At present, the distance between the fins is less than 2mm, and some even reach 1.2mm. When the heat exchanger of the air conditioner is working, the water vapor in the air is Water droplets are formed between the fins of the heat exchanger, and further water bridges are formed, which increases the air flow resistance and reduces the air volume, thus affecting the use effect of the air conditioner, and at the same time increasing energy consumption, causing noise and polluting the environment
Most of the existing air-conditioning aluminum foil coatings contain 8-10% organic solvents. During the film formation process of high-temperature baking, the solvents volatilize and cause pollution to the environment.
In addition, in order to improve performance, many air-conditioning aluminum foil coatings contain inorganic compounds such as silicon, aluminum, zirconium, etc., which makes the abrasive wear of the aluminum foil intensified during processing.
At the same time, in the existing air-conditioning aluminum foil coatings, many nano-materials are mentioned. Although they have good effects, they inevitably lead to harsh requirements for raw materials and increased costs.
At present, the requirements for the performance of hydrophilic coatings are getting higher and higher, and the testing methods are becoming more and more strict. Many of the existing air-conditioning aluminum foil coatings cannot meet the higher testing requirements.

[0031] Deionized water 500

[0032] Initiators are very commonly used in chemical processes, so I won’t go into details here; add the mixed component B to the reactor, stir, heat up to 80°C, drop in component A, drop it within 1.5 hours, and keep it warm at 80-85°C React for 4 hours, raise the temperature to 90°C, react for 1 hour, and cool down to below 50°C to obtain a water-soluble resin. During the reaction, the device is sealed so that the water will not evaporate and can be reused.

Abstract

The present invention relates to aluminum foil paint technology, and is especially one kind of no-solvent aluminum foil paint for air conditioner. The no-solvent aluminum foil paint consists of water soluble resin composition 5-10 wt%, curing agent 1-5 wt%, additive 0.1-2 wt% and water 80-90 wt%. The water soluble resin composition consists of double bond amino monomer 20-60 wt%, unsaturated organic acid or its salt 5-50 wt%, and functional monomer 10-30 wt%. The paint is applied to fins of heat exchanger in air conditioner, and after being roasted at high temperature to cross-link and cure, it form coating with high corrosion resistance, excellent hydrophilicity, no bad smell and high flowing water flush resistance.

Background technique: [0002] In recent years, air conditioners have been used more and more. With the impact of energy shortage, air conditioners are also developing towards miniaturization. At present, the distance between the fins of the heat exchanger in the air conditioner is getting smaller and smaller. At present, the distance between the fins is less than 2mm, and some even reach 1.2mm.
