Steel slag-doped anti-electrostatic ceramic brick

Abstract

The invention discloses a steel slag-doped anti-electrostatic ceramic brick which is characterized by being prepared from the following raw materials by weight: 3 to 5 parts of microlite, 6 to 8 parts of shell powder, 2 to 4 parts of germanium oxide, 30 to 50 parts of converter slag, 20 to 25 parts of talcum powder, 5 to 10 parts of kaolinite, 15 to 25 parts of micro waste glass powder, 1 to 2 parts of hydroxyethyl methyl cellulose, 2 to 4 parts of water glass powder, 2 to 4 parts of zinc oxide, 5 to 8 parts of brown sugar, 0.1 to 0.3 part of polyvinylpyrrolidone, and a proper quantity of distilled water. The ceramic brick has the advantages that static electricity can be eliminated due to the addition of oxidation germanium, so as to ensure people's body health; due to the addition of microlite, the weathering resistance, the weatherability and the contamination preventing capability of the ceramic brick can be enhanced; due to the addition of shell powder, the humiture of air can be adjusted effectively, and the ceramic brick is low in moisture regain and water seepage possibilities. The ceramic brick provided by the invention is wide in application range, beneficial to people's health, low in cost, high in decorative effect, and worth popularization.

Description

technical field [0001] The invention relates to the field of ceramic floor tile manufacture, in particular to an antistatic ceramic tile doped with steel slag and a preparation method thereof. Background technique [0002] my country is a big country of iron and steel, and about 150 kilograms of steel slag is produced for every ton of steel produced. Steel slag stacked in the slag yard occupies a large amount of land and pollutes the environment. For steel slag containing trivalent chromium, it will transform into hexavalent state after being placed in the open air for a long time, which will cause great harm to the ecological environment and the growth of animals and plants. Steel slag mainly contains calcium oxide, silicon dioxide, aluminum oxide, iron oxide, manganese oxide and carbon sulfide, and has potential gelling activity and broad application prospects. At present, it is of great social significance to study how to efficiently utilize steel slag to produce high va...

Problems solved by technology

Traditional ceramic tiles use high-quality kaolin, feldspar, clay, etc. as the main raw materials, and are prepared by wet pulverization and spray drying processes. However, this preparation method has high energy consumption and produces a large amount of water vapor, nitrogen oxides, and sulfur oxides Heavy pollutants such as waste and dust pollute the tail gas, which seriously pollutes the environment and seriously deviates from the requirements of clean production in the ceramic industry, and more and more kaolin is used in papermaking, coatings, fertilizers, refractory materials, rubber, plastics, petrochemicals and other industries. The raw materials for the ceramic tile industry are very scarce
