[0028] The present invention also provides the preparation method of described environment-friendly type EVA latex paint, and this method comprises the following steps:

[0029] (1) Add cellulose ether to the mixed solution of deionized water and propylene glycol, stir and disperse to obtain material a;

[0030] (2) Add 40-60% by mass of the above-mentioned water-based defoamer, water-based dispersant, water-based pH regulator, and water-based wetting agent in order to material a, and stir to obtain material b. The addition of water-based defoamer provides a better working environment for the other three additives, and the dispersant can make other additives and fillers better and more uniformly dispersed in the system. The pH regulator and the alkali to be added later The swelling thickener interacts to achieve a better thickening effect, and the wetting agent is to make a bedding for the filler added later to be better wetted.

[0031] (3) After mixing the filler and ash ca...

Abstract

The invention discloses environment-friendly EVA emulsion paint and a preparation method thereof. The emulsion paint is prepared from the following ingredients in parts by mass: 15 to 20 parts of EVA emulsion, 8 to 14 parts of spurrite powder, 35 to 45 parts of filling materials, 1 to 2 parts of propanediol, 0.2 to 0.4 part of cellulose ether, 0.6 to 0.8 part of water-based defoamers, 0.4 to 0.6 part of water-based dispersants, 0.3 to 0.5 part of water-based pH regulators, 0.2 to 0.4 part of water-based moisturizing agents, 1 to 1.5 parts of coalescing agents, 0.5 to 1 part of thickening agents, 0.2 to 0.4 part of preservatives and 22 to 30 parts of deionized water. The spurrite powder is added into the environment-friendly EVA emulsion paint, so that the defects of low scrub resistance and poor water resistance performance of the EVA emulsion paint are obviously overcome; the preparation method is simple; the adding sequence of the ingredients is used, so that the performance of each ingredient achieves the optimum; the scrub resistance performance, the water-resistant performance and the alkali resistance of the emulsion paint are improved.

Description

technical field [0001] The invention belongs to the technical field of architectural coatings, and in particular relates to an environment-friendly EVA latex paint and a preparation method thereof. Background technique [0002] Latex paint is a water-dispersible paint, which is made of synthetic resin emulsion as the base material, and the filler is refined by adding various additives after grinding and dispersing. Latex paint has many advantages that are different from traditional wall paints, such as easy to paint, fast drying, water-resistant paint film, and good scrub resistance. [0003] At present, most of the indoor decoration latex paints used in the society use styrene-acrylic emulsion and pure acrylic emulsion to make film materials, but they all have the disadvantages of strong odor and high cost. The film-forming materials in latex paints circulating on the market are mainly styrene-acrylic and pure acrylic emulsions, plus some other additives, which cause latex...
