Lightweight encaustic tiles in high strength

Abstract

A high-strength light-weight color tile is prepared from the Cl-O-Mg cement (inorganic glass) containing reduced MgO, MgCl2 and H2O, powdered coal ash, diatomite, quartz powder, PVA modified urea-aldehyde resin, polyacrylic acid solution and alkali-resistant short fibers through proportional mixing, spreading a layer of lattice fiber cloth, moulding while pressing, baking while solidifying, demoulding and coloring.

Description

technical field

[0001] The invention relates to a tile made of inorganic materials and organic materials, in particular to a high-strength and light-weight colored tile. Background technique

[0002] In the prior art, lightweight tiles are generally made of magnesium oxychloride cement, and its main components are magnesium oxide, magnesium chloride, glass fiber filaments or cloth. Due to the easy availability of raw materials, low cost, easy molding (can be formed into ordinary glass tiles, continuous imitation small blue tiles, imitation glazed tiles, imitation British red tiles, imitation Spanish tiles, etc.), high and low temperature resistance, and certain strength, etc. , has been promoted and used in some occasions. However, the existing magnesium oxychloride cement tile generally has the problems of moisture absorption and brine return and poor water resistance due to the relationship between its components. In addition, the manufacturing cost an...
