Formulation characteristics
Isolate whey protein is added to the interior and exterior wall latex paint.
Because the separated whey protein has film-forming properties after special treatment, it can form a film without adding any film-forming additives, making the interior and exterior wall latex paint a film-forming aid The content of the agent is greatly reduced, even to zero, which greatly reduces the content of VOC in the latex paint.
It is not only environmentally friendly, convenient construction, fast drying of the paint film, good air permeability, good water resistance, good alkali resistance, and performance.
It satisfies the requirements and other characteristics, and also has environmentally friendly functions such as short drying time, extremely low VOC content, and no pungent odor.
Application field
This product is widely used in large buildings, hospitals, hotels and other places with high environmental requirements.
It can also be used in the coating and protection of concrete precast panels, asbestos panels, and primed metal surfaces.
Recipe details
Production Method
- (1) Preparation of PWPI: prepare WPI (isolated whey protein) and deionized water with a resistivity of 15-18 Mn.
cm into an aqueous solution with a mass fraction of 8% to 10%, and then add a mass fraction of 0.Interior wall latex paint containing whey protein: deionized water 9.
The filler is one or a combination of lithopone, talc, heavy calcium carbonate, light calcium carbonate, kaolin, and wollastonite, and its specification is 400-1250 mesh.
Exterior wall latex paint containing whey protein: deionized water 9.
One or a combination of kaolin and wollastonite has a specification of 400-1250 mesh.
In addition to conventional emulsions, pigments, fillers, and additives, the latex paint for interior and exterior walls of this product also contains isolated whey protein extracted from milk as a film-forming substance.
Among them, the defoamer is a polysiloxane defoamer, such as BYK-024, BYK-025, BYK-026.
The additives are commonly used additives.
The neutralizer can be AF-95, AMP-95, etc.
The deionized water of this product is obtained by conventional methods.
