Problems solved by technology

[0003] With the enhancement of people's awareness of environmental protection and the objective requirements of environmental protection, the volatilization of a large amount of organic solvents during the coating process of aluminum ceilings will not only affect the performance of the coating film, but also damage the health of workers and cause environmental pollution.
In addition, there are deficiencies in the hardness and self-cleaning effect of baking-type coatings attached to the surface of aluminum ceilings

Abstract

The invention discloses a solvent-free UV (ultraviolet) coating for aluminum ceiling surfaces and a preparation method thereof, belonging to the technical field of coatings. The coating is prepared by mixing UV resin, HEAA (N-hydroxyethyl acrylamide), aluminum powder, a flattening agent and a photo-initiator. The solvent-free UV coating prepared by adopting the technical scheme of the invention has relatively good hardness through the synergistic effect between the components. Moreover, the solvent-free UV coating also has a relatively good self-cleaning effect, and researches discover that the contact angle between the coating of the technical scheme of the invention and the water surface is 170-180 degrees and the coating is not changed when an artificial accelerated aging test is performed on the coating (for 5000h).

Description

technical field [0001] The invention belongs to the technical field of coatings, and in particular relates to a solvent-free UV coating for the surface of aluminum ceilings and a preparation method thereof. Background technique [0002] Aluminum ceilings are generally divided into aluminum veneer ceilings, aluminum honeycomb ceilings, standard square ceilings, hanging piece ceilings, C-shaped bar buckle ceilings, U-shaped bar buckle combination ceilings, D-shaped bar buckle ceilings, aluminum strip ceilings, and round tube strips. Type ceiling, square tube strip ceiling, perforated ceiling, etc. Generally, the surface of the aluminum ceiling is a baking paint, which is different from the normal temperature drying or normal temperature curing paint. During the production and painting process and the baking process, it is easy to cause air bubbles when mixed with air or solvent volatilization. During the baking and curing process of baking coatings, if the solvent in the form...
