Water-soluble acrylic resin and hydrophilic coating prepared by using same

Abstract

The invention belongs to the technical fields of coatings and chemistry and relates to a water-soluble acrylic resin and a hydrophilic coating prepared by using the same. A water-soluble acrylic coating can be prepared after the resin is mixed with other substances, and can simultaneously ensure that peculiar smell can not be produced when an air-conditioner foil coating is roasted by the process at 180 DEG C for 5min and the heating mode of an air conditioner is started on the premise of ensuring high hydrophilicity. The smell evaluation grade is A. The technical scheme provided by the invention is as follows: the water-soluble acrylic resin comprises the following components by weight percent: 1-5% of special phosphate monomers, 5-9% of methyl(acrylic acid), 8-16% of methyl(hydroxyalkyl acrylate), 1-2 parts of crosslinking monomers, 0.3-1.5% of initiators, 0.01-0.1% of reducing agents and the balance of water. The water-soluble acrylic resin has the beneficial effects that the water-soluble acrylic coating can be prepared after the water-soluble acrylic resin provided by the invention is mixed with other specific substances, and can simultaneously ensure that peculiar smell can not be produced after the coating is roasted and heated on the premise of ensuring high hydrophilicity.

Description

[0001] technical field [0002] The invention belongs to the technical field of paint and chemistry, and relates to a water-soluble acrylic resin and a hydrophilic paint made from it. Background technique [0003] When the air conditioner is cooling, the water vapor in the air condenses and adheres to the surface of the heat dissipation fins of the air conditioner heat exchanger, forming a "water bridge" between the fins, resulting in increased ventilation resistance, increased noise, and a decrease in the working efficiency of the heat exchanger , energy consumption increases. At present, the common technology to solve this problem is to coat a layer of corrosion-resistant and highly hydrophilic water-soluble acrylic resin coating on the surface of the aluminum foil used to produce the fin. However, this brings about two other problems. First, there is a process of baking fin oil in the process of aluminum foil being processed into fins. The baking process is 180°C*5mi...

Problems solved by technology

However, this brings about two other problems. First, there is a process of baking fin oil in the process of aluminum foil being processed into fins. The baking process is 180°C*5min. Under this condition, the coating Produces unpleasant odors containing harmful substances, seriously affecting air quality and human health; second, when the air conditioner is in the heating mode, the hot air continuously bakes and heats the coating. Under this condition, the coating will also Produces unpleasant odors containing harmful substances, seriously affecting air quality and human health

[0004] However, there is currently no water-soluble acrylic paint on the market that can ensure high hydrophilicity while ensuring no peculiar smell after the coating is baked. In addition, from the composition of water-soluble acrylic paint, water-soluble acrylic resin It is an important component, which determines whether the coating is hydrophilic and its combination with anti-corrosion coatings. Furthermore, there is no water-soluble acrylic resin on the market that can be formulated with other substances to prepare the above-mentioned coatings.
