Abstract

The invention belongs to the field of paint and particularly discloses a preparation method of antibacterial nano latex paint for interior walls. Firstly, a precursor colloidal solution of a silver / titanium dioxide nanotube is prepared; a precursor product obtained through spinning is immediately cooled after electrostatic spinning, then put into a muffle furnace and sintered at a constant temperature, and the silver / titanium dioxide nanotube is obtained; the silver / titanium dioxide nanotube is dispersed in water under the condition of stirring, and propylene glycol, a coalescing agent, a wetting agent, a preservative, hydroxyethyl cellulose and a dispersing agent are added and stirred in a grinder to be mixed uniformly; titanium dioxide, triple superphosphate, kaolin and talc powder are added and sufficiently ground in a high-speed grinder, and an acrylic emulsion, a defoaming agent and a thickening agent are added; finally, the mixture is stirred to be uniformly mixed in the grinder, filtered and packaged in barrels, and a finished product of the antibacterial nano latex paint for the interior walls is obtained. The antibacterial nano latex paint for the interior walls is aimed to solve the problem of breeding of bacteria on interior walls of a room and mildewing of the interior walls due to humid weather lasting for a long time.

Description

technical field [0001] The invention relates to the field of coatings, in particular to a preparation method of antibacterial interior wall nano-emulsion paint. Background technique [0002] Driven by the construction industry, China's coatings industry is growing from strength to strength. Statistics show that in 2011, the total output of China's architectural coatings was about 3.5182 million tons, an increase of more than 30% year-on-year. It can be seen that although China's architectural coatings industry has experienced the impact of the global financial crisis in 2008 and the pressure brought by rising raw material prices, its development momentum remains unabated, and it still maintains a relatively high growth rate. [0003] Interior wall paint is an essential material for home decoration. At present, with the enhancement of people's awareness of environmental protection, the requirements for interior wall latex paint for decoration are getting higher and higher, a...
