Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of building materials, and particularly relates to a water-based artistic paint and a preparation method thereof. BACKGROUND

[0002] With the rapid development of economy, people's demand for the environment around them is increasing, and in addition to meeting the use requirements and material functions, more attention is paid to the demand for environmental atmosphere, cultural connotation, artistic quality and other spiritual functions. Traditional wall paint is mostly single-color latex paint, and the effect created is relatively simple, and the product mode is also relatively the same. The latex paint market is gradually saturated, and paint manufacturers have been looking for new selling points and breakthroughs in latex paint. As a new concept of wall material, artistic paint pays attention to the creation of space atmosphere, pursues construction technology, and uses color, texture and process details to highlight the value of paint, creating a fashionable space and decorating people's life. Artistic paint is more and more loved by people.

[0003] The components of artistic paint mainly include film-forming material, pigment, filler, solvent and various additives. The film-forming material as the base material of the paint directly affects the performance of the coating. The existing film-forming material is mainly acrylate resin, which has good film-forming performance and film resistance. However, the water resistance of acrylate resin is generally poor, and it is easy to swell and cause the coating to peel under the condition of immersion or long-term water penetration. The existing research results show that the use of fluorine-modified acrylate resin can improve the water resistance to a certain extent. However, fluorine has poor compatibility, which causes segregation in the paint, resulting in a decrease in the adhesion of the coating to the substrate, and the coating has high internal stress, which makes the coating easy to fall off when subjected to external wear, so that the overall wear resistance of the coating is poor.
