Problems solved by technology

[0005] However, the latex paints currently on the market are prone to stains, and it is difficult to clean them after contamination.
Even with the addition of anti-graffiti additives, stains can still penetrate deep into the coating, and the stains spread during cleaning, making it difficult to completely remove the stains
In addition, the latex paint has low hardness and is easy to lose powder after being scratched. It also does not have the ability to resist formaldehyde and antibacterial. Obviously, it cannot meet the requirements of multi-function and high performance.

Abstract

The invention discloses an antibacterial anti-formaldehyde stain-resistant highly hard multifunctional water-based coating and a preparation method thereof. A chemical reaction of two-component functional groups is utilized, the crosslinking density and compactness of the coating are improved, the stain resistance, mildew resistance and hardness of the coating are significantly superior to those of emulsion paint, and a functional nanometer material is introduced and has the capacity of resisting bacteria, removing formaldehyde and purifying air at the indoor temperature; the coating does notcontain formaldehyde, is healthy, friendly to the environment, proper in cost and excellent in various physical properties. Stain-resistant coatings on the market are mostly prepared by adding a special organosilicone emulsion or hydrophobic assistants, are generally high in cost, not good in stain-resistant effect and poor in scrubbing-resistant and stain-resistant effects and do not have the functions of resisting bacteria and removing formaldehyde; the multifunctional water-based coating utilizes a photocatalyst for degrading VOC such as the formaldehyde into water and carbon dioxide, secondary discharge does not exist, and the hardness of the coating is high; after being scratched, the coating cannot crack, the coating powder falling phenomenon cannot occur, and the coating further hasgood capacity of resisting water and mould.

Description

[0001] Technical field: [0002] The invention relates to the field of architectural coatings, in particular to a formaldehyde-resistant, anti-bacterial, stain-resistant, high-hardness multifunctional water-based coating and a preparation method thereof. [0003] Background technique: [0004] With the improvement of people's living standards, people pay more and more attention to the quality of life, and the requirements for the living environment are getting higher and higher. As an important part of home decoration, wall coatings have also attracted much attention. In addition to requiring water-based environmental protection for wall coatings, functional requirements are also put forward for walls used in hospitals, schools and residences. As a place with dense traffic, medical institutions are also places where multiple germs exist widely. Some specific places in hospitals are often polluted by blood stains, medical reagents, oil stains, etc. Therefore, wall coatings are r...
