Abstract

The invention relates to an environment friendly bacterium-resisting and smell-removing thermal insulation latex coating which is suitable for coating an inner wall and an outer wall. The environment friendly bacterium-resisting and smell-removing thermal insulation latex coating comprises inorganic nano particle / modified acrylic ester emulsion, SiO2 aerogel, a pigment filler, a thickening agent, a dispersing agent, a flatting agent and a film-forming additive. By using two functions of the inorganic nano particle / modified acrylic ester emulsion and the SiO2 aerogel, the coating is endowed with multiple functions of resisting and killing bacteria, removing smell, blocking and insulating sound, insulating heat and preserving heat.

Description

technical field [0001] The invention relates to an environment-friendly, antibacterial, odor-cleaning and heat-insulating latex paint suitable for interior and exterior wall painting. Background technique [0002] With the continuous improvement of the requirements for environmental protection and energy conservation, green and energy-saving coatings are an important development direction. It is not only required that the coating is harmless to people's health and the environment, can be antibacterial, sterilized, and purifies the air, but also has the functions of heat insulation and heat preservation. Therefore, high-performance, green and healthy water-based coatings will become a hot spot in the future market. [0003] At present, the environment where people live, live and work, especially the atmospheric environment, breeds many pathogenic bacteria and viruses that endanger human physical and mental health, as well as harmful gases caused by production and life, causi...
