Aggregate for preparing dust-free cement-based ceramic binder and preparation method thereof

The invention relates to aggregate for preparing a dust-free cement-based ceramic binder and a preparation method of the aggregate. The aggregate is prepared from the following aggregate and a proper amount of liquid material, wherein the aggregate is one or any mixture of more than two of 50-100-mesh river sand; the liquid material is mainly prepared from the following components: acrylic copolymer emulsion, water, a negative ion agent, a penetrating agent, a dispersing agent, a defoaming agent and a coalescing agent. The invention overcomes the defects that the traditional cement-based ceramic binder is easy to generate a large amount of dust pollution in the stirring process of production and use and is not beneficial to the environment and human health, and most of the existing dust-free mortar needs other additives and is inconvenient to prepare and use, high in cost and the like. According to the present invention, the aggregate can perform adhesion and negative ion adsorption on cement and other minera
