Description

Technical Field

[0001] The invention relates to the technical field of water paints, and in particular to a jade-based formaldehyde-free water paint for interior walls and a preparation method thereof. Background Art

[0002] As society progresses, people's expectations for their living environment are becoming increasingly stringent. However, it's common for newly renovated homes to experience excessive air quality. This is primarily due to the release of large amounts of gaseous pollutants from renovation and furniture materials. The main gaseous pollutants in indoor air include formaldehyde, benzene-based pollutants (such as benzene, toluene, and xylene), ammonia, and TVOC. Formaldehyde, a highly irritating substance, is one of the most serious indoor air pollutants.

[0003] Water-based paint is a paint that uses water as a diluent. It has the characteristics of energy saving and environmental protection, non-flammable and non-explosive, ultra-low emissions, low carbon and health. The paint film is plump, flexible, water-resistant, wear-resistant, aging-resistant, yellowing-resistant, and easy to use. It can be widely used on various materials such as wood, metal, industrial coatings, plastics, glass, and building surfaces. Water-based paint is an updated product that gradually replaces oil paint. The promotion of water-based coating is a revolution in China's coating industry.

[0004] At present, water-based paint is widely used in decoration and other fields due to its unique properties. The existing water-based paints on the market are often used in the decoration painting process.
