Far infrared functional brick and its producing method

Abstract

The invention relates to building material such as ground tile and wall tile capable of producing negative ions and being radioactive-ray-free and process for its preparation, the tiles comprise the components of (by weight percentage) silicon dioxide 31.5%-33.5%, aluminum oxide 7.0%-8.5%, potassium oxide 0.5%-1.0%, ferric oxide 2.0%-2.5%, diboron trioxide 1.5%-3%, sodium oxide 0.5%-1.5%, pottery clay 50%-57%. The preparation process comprises the steps of, disintegrating the raw material to grain size of 0.03 mm, watering and stirring, immersing, making blank, burning 8 hours at 1000 deg. C to 1500 deg. C.

Description

Technical field: [0001] The invention relates to a building engineering material, in particular to building materials such as floor tiles and wall tiles capable of generating negative ions and without radiation, and a manufacturing method thereof. Background technique: [0002] Silicate minerals, also known as tourmaline. Its main components contain Na, Fe, Mn, Al, Li, B, Si and other elements, and its molecular expression is X 1 Y 9 B 3 Si 6 (OH·F) 4 , X represents one or more elements of Ca, Na, K, Mn, Y represents one or more elements of Mg, Fe, Al, Cr, Ti, Li, Mohs hardness 7-7.5, This substance has been developed and utilized in many fields such as water activation, sewage treatment, air purification, washing, and fertilizer. Japanese Patent No. JP2000139207 reports that this material is used as a fertilizer. At present, there is no information documenting the use of tourmaline on floor tiles and wall tiles for construction. At present, floor tiles and wall tile...

AI Technical Summary

Problems solved by technology

At present, the floor tiles and wall tiles used at home and abroad are made of marble, imitation marble, terrazzo or porcelain products. Most of them are produced by radiation and other radiation in use, and will not produce the effect of purifying the air and generating negative ions.
