Water-soluble acrylic resin and preparation method thereof

Abstract

The invention discloses a water-soluble acrylic resin which comprises functional monomers, (methyl)acrylic acid, (methyl)hydroxyalkyl acrylate, acrylamide, an initiator, a reducer and water. The waterborne resin can not become yellow, has the advantages of high outdoor weather resistance, favorable dispersity for pigment, low cost, favorable water solution resistance, favorable punching oil resistance, favorable solvent resistance, high formability, favorable heat resistance, favorable bending resistance, no odor and simple production technique, and is in the leading position in China. The water-soluble acrylic resin can be widely used for surface coating of aluminum and aluminum alloy products, and especially for coating surfaces of heat exchanger fins of air conditioners.

Description

technical field [0001] The invention belongs to the technical field of paint and chemistry, and relates to a hydrophilic water-soluble acrylic resin coated on the surface of aluminum and aluminum alloy products, especially on the fin surface of a heat exchanger of an air conditioner, and a preparation method thereof. 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 miniaturization, light weight and high performanc...

Problems solved by technology

[0003] When the air conditioner is cooling, the water vapor in the air condenses and adheres to the surface of the fins, forming a "water bridge" between the fins, resulting in increased ventilation resistance, increased noise, decreased work efficiency of the heat exchanger, and increased energy consumption; aluminum foil If it is directly used for radiator fins, the air conditioner used in both heating and cooling rooms is in a dry-wet environment during use, forming an oxygen concentration battery, which is easily corroded and generates Al 2 o 3 .3H 2 The white powder of O, commonly known as "white powder", in a humid environment, causes mold to grow in the heat exchanger, and is sent into the room with the wind to pollute the environment
