Problems solved by technology

Traditional ceramsite surface colorants mostly use colored glaze, which uses high-purity chemical products as the main raw material, and is manufactured into a slurry that is sprayed on the surface of ceramsite and then baked and solidified at a high temperature. The middle color layer is easy to peel off and decolorize, and the cost of the colorant is relatively high

Abstract

The invention discloses a ceramsite coating with iron ore as a main raw material. The ceramsite coating is characterized by being prepared from the following raw materials in percentage by weight: 75-93 percent of iron ore, 0-12 percent of glass, 2-5 percent of bentonite, 3-6 percent of fused alumina zirconia, 1-4 percent of lead oxide and 0.2-0.5 percent of borax. The ceramsite coating can form a bronzing coating on the surface of ceramsite, has strength and hardness equivalent with those of a ceramsite body, and does not bare the color of a ceramsite blank body when having little abrasion, and the service life of colorful ceramsite can be greatly prolonged.

Description

technical field [0001] The invention belongs to the technical field of engineering and building materials, and in particular relates to a ceramsite coating with iron ore as the main raw material. Background technique [0002] Because of its good water permeability, low cost and good raw material applicability, ceramsite has been more and more widely used in municipal construction, landscaping and other projects. The color of ceramsite surface is also more and more abundant, among which reddish brown There is more demand for ceramsite. Traditional ceramsite surface colorants mostly use colored glaze, which uses high-purity chemical products as the main raw material, and is manufactured into a slurry that is sprayed on the surface of ceramsite and then baked and solidified at a high temperature. The middle color layer is easy to peel off and decolorize, and the cost of its colorant is relatively high. Contents of the invention [0003] The technical problem to be solved by...
