Abstract

The present invention relates to one kind of nanometer inorganic powder modified water emulsion as multifunctional wall paint and its preparation process. The water emulsion as wall paint features containing nanometer inorganic composite powder in 0.5-5 wt%, and the nanometer inorganic composite powder consists of nanometer zinc oxide 1-5 wt%, other nanometer oxide 1-5 wt% and tourmaline powder 90-98 wt% and is produced through surface treatment. The water emulsion as wall paint is prepared through conventional latex preparing process including mixing, high speed dispersing, regulating and other steps. The water emulsion as wall paint has excellent physical performance, can release negative ion to purify air and kill bacteria to provide people with excellent living environment.

Description

technical field [0001] The invention relates to a multifunctional water emulsion wall paint modified by nano-inorganic composite powder and a preparation method thereof. Background technique [0002] The function of traditional interior wall coatings is to make the wall surfaces of rooms and corridors clean and beautiful, and have a large light reflectivity to make the spaces of rooms and corridors bright. With the development of modern technology and the needs of meeting various purposes, the types and functions of interior wall coatings are constantly increasing. However, due to the widespread use of latex paint for interior walls, adverse reactions such as irritation, fatigue, headaches, and memory loss have occurred in many countries. The test results show that this is related to the pollution of volatile organic compounds in architectural coatings. All countries in the world are currently committed to the research and development of low-VOC latex paint, but in the lat...
