Abstract

The invention discloses a high-color-retention water-based paint and a preparation method thereof. The high-color-retention water-based paint comprises high-color-retention water-based paint of a latex paint system and / or high-color-retention water-based paint of an inorganic paint system. The preparation method comprises the following steps: adding raw materials of the high-color-retention water-based paint of the latex paint system and / or raw materials of the high-color-retention water-based paint of the inorganic paint system inorganic paint system into a stirrer in batches, adding water, carrying out stirring, finally adding a polyvinylenedifluoride emulsion and pigment color paste for color adjustment, adding a defoaming agent, and carrying out stirring to obtain a finished product. The high-color-retention water-based paint provided by the invention has the characteristics of high weather resistance and color retention, so that the finally prepared paint has good color retention.Weather resistance and chemical corrosion resistance of the paint can also be enhanced, and particularly, the defects that an existing latex-paint exterior wall paint material is poor in weather resistance and fades easily are overcome. The high-color-retention water-based paint is an ideal selection of bright wall marks for religious temples, kindergartens, outdoor advertisements and the like. The application range is wide, maintenance is easy, and cost performance is high.

Description

technical field [0001] The invention relates to an inorganic high molecular polymer, in particular to a water-based paint with high color retention made from latex paint, silicate inorganic paint, polyvinylidene fluoride emulsion, and pigment paste and a manufacturing method. Background technique [0002] The current exterior wall paint mainly uses acrylic emulsion as a film-forming binder, adding pigments, solvents, additives, and exterior wall decoration materials after deployment. Exterior wall coatings are widely used and promoted for beautifying and protecting the wall surface, which has the effect of being beautiful, clean and protective. However, the exterior wall coatings in the prior art have poor weather resistance, and the problem of discoloration is an insurmountable problem for the existing exterior wall coatings. Although silicate inorganic coatings have good weather resistance, they also have the problem of fading. Therefore, need a kind of new ultra-weather...
