Abstract

The invention discloses an aqueous high-content nanometer calcium carbonate dispersoid and a preparation method of the aqueous high-content nanometer calcium carbonate dispersoid. The aqueous high-content nanometer calcium carbonate dispersoid comprises the following ingredients through being metered by the total mass percentage: 40.0 to 60.0 weight percent of nanometer calcium carbonate, 5.0 to 10.0 weight percent of surface modifying agents, 2.0 to 6.0 weight percent of wetting agents, 6.0 to 15.0 weight percent of dispersing agents, 5.0 to 10.0 weight percent of functional additives, 0.2 to 0.5 weight percent of pH value conditioning agents and the balance de-ionized water, wherein the dispersing agents are formed by the self preparation of three polymerizable monomers through reaction. The aqueous high-content nanometer calcium carbonate dispersoid can replace nanometer calcium carbonate powder of the same quantity in the paint preparation process, in addition, the calcium carbonate dispersoid is easily dispersed, and the performance of the paint in multiple aspects of water resistance, washing resistance, stain resistance, construction performance and the like.

Description

technical field

[0001] The invention relates to a nano-calcium carbonate dispersion and a preparation method thereof, in particular to a water-based high-content nano-calcium carbonate dispersion and a preparation method and application thereof in the field of slurrying of coatings, pigments and fillers and their applications. Background technique

[0002] Compared with decorative materials such as facing bricks, granite, mosaics, and aluminum alloy glass curtain walls, architectural coatings have the advantages of low cost, high safety, good decoration, easy renewal, and little environmental pollution. In industrially developed countries, building exterior walls use 80-90% of high-grade coatings are decorated, and architectural coatings account for about 50% of the total output of coatings. In my country, as the country and government departments at all levels restrict the use of building materials such as glass curtain walls and floor tiles, architectural coatings occupy a...
