Embodiment Construction

[0006] The base material is selected using reduced MgO-MgCl 2 -H 2 O system, that is, magnesium oxychloride cement (inorganic glass fiber reinforced plastic) composite components. The system introduces MgO from lightly burned powder, and introduces MgCl from refined halogen flakes. 2 , H 2 O is well water without CI. When the concentration of the halogen sheet solution is constant (25-30°Be), and the MgO content in the lightly burned powder is 85-90%, the ratio (Wet) of the lightly burned powder to the brine is in the range of 0.8-1.4, and the crystal phase structure 5Mg(OH 2 ).MgCl.8H 2 O (abbreviated as 5.1.8 crystal phase), high-strength magnesium composites are expected to be obtained. Add organic admixtures such as PAV modified urea-formaldehyde resin, polyacrylic acid liquid, etc. to the ingredients to block capillary channels and prevent the seepage of MgCI and the infiltration of external moisture. In addition, active filler substances, such as fly ash, diatomac...

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...
