Embodiment Construction

[0029] The present invention will be further described below through specific embodiments, but it is not meant to limit the protection scope of the present invention.

[0030] (1) Preparation of primer A

[0031] Weigh various raw materials according to the formula ratio, weigh appropriate amount of modified epoxy resin, modified acrylic resin, amino resin, ethylene glycol butyl ether, put them into the reaction kettle, start the stirrer, mix evenly, and add PH regulator Adjust the pH value of the system to 7-8, add metered distilled water to keep the solid content of the system at 25%, and prepare component A.

[0032] (2) Preparation of surface coating B

[0033] Weigh various raw materials according to the formula ratio, weigh an appropriate amount of functional monomers, methacrylic acid, and hydroxy acrylate, put them into the reaction kettle, start the stirrer, mix well, and then slowly add an appropriate amount of initiator and an appropriate amount of The composition...

Abstract

The present invention discloses one kind of anticorrosive hydrophilic paint, which consists of prime paint A and surface paint B. The prime paint A consists of modified epoxy resin, modified acrylic resin, amino resin, butyl glycol ether, distilled water, etc; and the surface paint B consists of functional monomer in the structure of CH2=CR1-R2-CH2-CHR3-CH2SO3M, methacrylic acid, hydroxyl acrylate, initiator, distilled water, etc. The anticorrosive hydrophilic paint has high corrosion resistance, high hydrophilicity, high water tolerance, high solvent tolerance and other advantages. It may be painted to the surface of aluminum and aluminum alloy product, especially heat exchanger of air conditioner.

Description

technical field [0001] The invention belongs to the technical field of coatings and chemistry, and relates to a coating combination with good corrosion resistance and high hydrophilicity, which is coated on the surface of aluminum and aluminum alloy products, especially on the surface of heat exchanger fins of air conditioners substances and preparation methods. Background technique [0002] With the continuous improvement of people's living standards, the use of air conditioners is increasing year by year. In 2005, my country produced 53 million air conditioners and consumed 200,000 tons of aluminum foil. The use of air conditioners is more popular, but during the long-term use of air conditioners, there will be many problems such as increased power consumption, dust pollution, peculiar smell, and bacterial growth. With the promulgation of the National Energy Conservation Law and the Environmental Protection Law, air conditioners continue to develop in the direction of mi...
