Abstract

The invention discloses gypsum marble and its preparation method. The gypsum marble is composed of a calcium sulfate hemihydrate, dispersible fibers, a modifier, colored powder and clear water in a weight ratio of 100:3.0-5.5:0.5-1.8:0.03-7.0:18.63. With a reaction mechanism of hydrating the calcium sulfate hemihydrate into a calcium sulfate dihydrate by the above materials, the preparation method consists of powder metering, powder mixing, continuous semi-wet stirring, compression moulding, section cutting and polishing, as well as surface treatment. And the technical conditions that the moulding water is hydration structural water and the compression time is the hydration time can be realized. The microstructure of the marble crystal is in a compact plate structure. Comparing favorably with natural stones in terms of macroscopic physical and mechanical properties, the gypsum marble of the invention has substantially better product, production process condition and environment coordination than natural facing stones, cement-based and resin-based artificial stones.

Description

technical field [0001] The invention relates to a gypsum marble and a preparation method thereof, belonging to the technical field of building materials. Background technique [0002] There are two types of stone for architectural decoration: natural stone and imitation stone. There are two main types of natural stone used in architectural decoration: granite and marble. Imitation stone can be divided into organic imitation stone and inorganic imitation stone. According to different production processes, it mainly includes polyester-based imitation stone, composite-based imitation stone, and silicate-based imitation stone. [0003] Natural stone is made of natural stone blocks by sawing and surface processing. It has high strength, hardness, and excellent structural properties such as wear resistance and durability, but is limited by natural resources and a single surface treatment method. , its decorativeness and series integration have yet to be developed and improved; ...
