Abstract

The invention discloses emulsion paint containing attapulgite and a preparation method for the emulsion paint containing attapulgite. The method mainly comprises the following steps of: sequentially adding water, cellulose, a dispersing agent SN-5040, a mildew preventive, an aid AMP-95, alcohol ester-12, poly ethylene-100 (PE-100), a defoaming agent JR-321, propylene glycol, 1,000-mesh triple superphosphate, talcpowder, titanium dioxide, the attapulgite, an aid BYK022, an emulsion SD-818, a thickening agent RM2020 and a thickening agent AR-235 which serve as raw materials in a weight ratio, mixing and dispersing to obtain the emulsion paint. According to the emulsion paint, the used attapulgite has an obvious thixotropic thickening effect, prevents pigments from settling, can improve the synaeresis phenomenon of paint films, and has the effects of sagging prevention and splashing resistance; the uniformity of the surfaces of the paint films is improved; and a thickening effect of the attapulgite is different from that of the cellulose, namely the attapulgite has a certain antibacterial property and a certain mildew-resistant property, and improves the tinctorial power of the pigments and the covering capacity of coatings.

Description

technical field [0001] The invention relates to a latex paint containing attapulgite and a preparation method thereof. Background technique [0002] Attapulgite clay refers to a clay mineral whose main component is attapulgite. Attapulgite is a crystalline hydrated magnesium aluminum silicate mineral with a unique layered chain structure. There is lattice replacement in its structure, and the help crystals contain variable amounts of Na+ and Ca 2+ , Fe 3+ 、Al 3+ , The crystals are needle-like, fibrous or fibrous aggregates. Attapulgite has good colloidal properties such as unique dispersion, high temperature resistance, salt and alkali resistance, and high adsorption and decolorization ability. And has a certain degree of plasticity and cohesion, its ideal chemical formula is: Mg 5 Si 8 o 2 0(OH) 2 (OH 2 ) 4 4H 2 O. It has an intermediate structure between a chain structure and a layered structure. Attapulgite is earthy, compact and massive, produced in sediment...
