Check the formula of antibacterial latex paint for interior walls

Formulation characteristics

The interior wall antibacterial latex paint adopts low volatile organic compound (VOC)-pure acrylic emulsion, which makes full use of the excellent film characteristics of low VOC pure acrylic emulsion; at the same time, new antibacterial agents and functional additives are introduced, which can achieve the paint film In addition to maintaining good physical and chemical properties of the paint film.

Such as gloss and color retention, adhesion, water resistance, alkali resistance, washing resistance, stain resistance, leveling, etc.

The manufacture of interior wall antibacterial latex paint pays attention to the selection of suitable pigments, fillers and leveling agents, defoamers, thickeners and other additives to ensure the excellent surface state of the paint film, various physical and chemical properties and antibacterial properties, and meet current user requirements The need for long-term antibacterial.

Application field

This product is mainly used in interior wall coatings.

Recipe details

Production Method

• (1) Add tap water, dispersant, wetting agent, defoamer, antifreeze ethylene glycol, titanium dioxide, and filler into the mixing container and stir evenly.
  
  

  Colloidal nano SiO2 20~50, tap water 300~450, dispersant 50~100, wetting agent 1~2, defoaming agent 3~5, thickening agent 5~10, antifreeze 100~200, antifungal agent 3~ 5.

  
  

  The filler is one of heavy calcium carbonate, light calcium carbonate, talc and kaolin.

  
  

  The colloidal nano SiO2 is a functional additive, and its function is to optimize the low-VOC emulsion, pigments, fillers, dispersants, high-boiling point film-forming additives and other raw materials of the interior wall antibacterial latex paint, and at the same time, to further improve and increase the coating The comprehensive performance of the layer, based on a large number of experiments, optimized the selection of colloidal nano SiO2 functional additives.

  
  

  The addition of nano-level materials to latex paint can greatly reduce the free volume between the pigment and the film-forming base material in the latex paint, greatly increase the filling ratio, improve the mechanical strength of the coating, increase the washing resistance of the coating, and increase the coating The compactness and flatness of the surface of the layer, thereby improving the stain resistance of the coating.

  
  

  In addition, nano-materials have a great specific surface area and surface activity.
