Description

Technical Field

[0001] The invention relates to the technical field of building decoration materials, and in particular to an interior wall composite material and a preparation method thereof. Background Art

[0002] With the development of modern industrial technology, solvent-based coatings have been basically eliminated in architectural coatings due to their great harm to the environment and human health. Water-based architectural coatings have a cleaner process, and their energy consumption, emissions and toxicity are much lower than those of solvent-based coatings, so they have gradually become the mainstream of architectural coatings. However, with the increasing requirements of countries around the world for environmental protection and energy conservation and emission reduction, mainstream water-based organic coatings using acrylic resins and polyurethane resins are also facing the situation of being gradually replaced by new functional products that are more energy-saving and environmentally friendly, such as new environmentally friendly coatings that highlight the functions of odor removal and formaldehyde absorption, and use photocatalysts, nanometers, bamboo charcoal, diatom mud, shell powder and the like as selling points. However, although such environmentally friendly products are more environmentally friendly and have more significant energy-saving and environmental protection effects, these new coatings have a common defect, that is, they do not have heat storage properties.
