Wear-resisting artificial color sand and preparation method thereof

Abstract

The invention discloses wear-resisting artificial color sand and a preparation method thereof. The wear-resisting artificial color sand is prepared from raw materials in parts by mass as follows: 1000 parts of sand grains, 30-60 parts of a binding agent, 5-20 parts of inorganic pigment, 0.1-2 parts of a polymeric dispersant, 1-5 parts of borax and 30-80 parts of water, wherein the binding agent is an inorganic binding agent prepared from an aluminium dihydrogen phosphate solution and sodium silicate through mixing; the polymeric dispersant is a terpolymer dispersant prepared from water as a solvent, maleic anhydride (MA), acrylic acid (AA) and butyl acrylate (BA) as monomers, ammonium persulfate as an initiator and isopropyl alcohol as a chain transfer agent. A product has quite high wear resistance, is not dissolved in acid and alkali and has pure and stable color, the color sand in required color can be formed by mixing color sand in different colors and different mass ratios, and demands of the real stone paint market are met better; the preparation method is convenient to operate, the sintering temperature is low, and the preparation method has the advantages of being energy-saving, environmentally friendly and low in cost.

Description

technical field [0001] The invention relates to the field of functional sand materials, in particular to a wear-resistant artificial colored sand and a preparation method thereof. Background technique [0002] As a surface decoration material, colored sand has the advantages of bright colors, stable performance and environmental protection, and has been widely used in the field of architectural decoration. In recent years, due to the development of the construction industry, the market demand for colored sand is increasing. The limited reserves of natural colored sand can no longer meet the market demand. At the same time, natural colored sand is obtained by directly crushing natural colored ores. Most of them are chaotic in color, poor in strength, and easy to differentiate; while brightly colored colored sand is rare and expensive. Compared with natural colored sand, artificial colored sand has stable properties and convenient color matching. By changing the ratio of pigm...
