Problems solved by technology

Due to the relatively high solubility of zinc oxide in water, it has high selectivity to dispersants, thickeners and pigments and fillers. It is greatly affected by the pH value and the stability of the coating is poor, which also limits its promotion in coatings.
Existing commercially available coating products are generally not environmentally friendly, cannot effectively eliminate toxic and harmful substances and odors; cannot realize industrialization, and have poor negative ion release, etc.

Abstract

The invention relates to a nano-zinc compound anion environmentally-friendly latex paint and a preparation method thereof. The preparation method comprises: (1) weighing raw materials; (2) mixing and stirring deionized water, a dispersant, a wetting agent, a mildew preventive, a bactericide and an antifreeze, then adding titanium dioxide and an environmentally-friendly negative ion functional material, stirring, adding kaolin, heavy calcium carbonate powder and nano-zinc compounds, continuing stirring, adding a rheology modifier and a whitening agent and continuing stirring; (3) adding a defoamer and hydroxyethyl cellulose, mixing and stirring, then adding a film-forming aid, grinding and standing to obtain slurry; and (4) adding acrylic resins, stirring, then adding a pH regulating agent and a base swelling thickener and continuing stirring. The product provided by the invention has the advantages of strong hiding capability, convenience in construction, no toxicity and odor, no environmental pollution, and bactericidal and mildew-proof effects; and the wall paint can sustainably release negative ions, effectively eliminate the toxic and hazardous substances and odor and achieve industrialization, and has scrubbing resistance and high release amount of negative oxygen ions.

Description

technical field [0001] The invention relates to a latex paint and a preparation method thereof. Background technique [0002] Environmentally friendly architectural decorative coatings are a high-tech industry that has been booming in China in the past ten years. With the needs of the construction industry and architectural decoration, latex paints are widely used on the surface of walls, some for exterior walls, and some for interior. For walls, the environmental protection requirements for interior walls are usually higher than those for exterior walls. Because the indoor ventilation is lower than that of the outdoors, people put forward low-toxicity requirements indoors. The most basic requirement is that the latex paint should not volatilize directly toxic substances to humans or animals, or have a low volatile value. Therefore, a large number of latex paints are currently required to be environmentally friendly. type latex paint. [0003] The preparation of environmen...
