preparation example Construction

[0031] see figure 1 , the second aspect of the present invention provides a method based on deposition and CO 2 A method for preparing a driven-solidified artificial stone, comprising the following steps:

[0032] Mix the multi-grade powder with water evenly to make a slurry;

[0033] Allow the slurry to stand and deposit to form a green body, and carbonize and maintain the green body to form an artificial stone with calcium carbonate as the matrix.

[0034] In the present invention, the step of uniformly mixing the multi-graded powder with water to make a slurry is specifically: uniformly mixing the gelling material, inert filler, and inorganic pigment to obtain a dry material, dissolving the admixture in water and then stirring to dry material and mix evenly into a paste.

[0035] In the present invention, a mold with a smooth surface is selected to make the surface of the formed artificial stone smooth.

[0036] In the present invention, the material of the mold is one ...

Abstract

The invention relates to an artificial stone based on a deposition method and CO2 driven consolidation and a preparation method thereof. The artificial stone based on the deposition method and CO2 driven consolidation is formed by uniformly mixing multi-graded powder containing a cementing material with water, then forming a closely-packed green body structure through the natural deposition effect of the multi-graded powder and then carbonizing under the action of CO2 gas. According to the invention, the raw material composition of the artificial stone is all inorganic materials, the matrix composition is calcium carbonate and is close to natural limestone stone, high-temperature pressing or sintering is not needed in the preparation process, the requirement for equipment and mold is low through a natural deposition pouring forming method, the surface of the artificial stone shows a ceramic glaze-like effect after demolding, grinding and polishing are not needed, the preparation cost is low, the process is simple, the artificial stone forms cemented hardening strength through a mineralization reaction of CO2 gas, CO2 can be effectively solidified in the preparation process, organic adhesives such as unsaturated polyester or polymethyl methacrylate and other resins do not need to be used, the weather resistance is good, and good environmental protection benefits are achieved.

Description

technical field [0001] The invention relates to the field of artificial stone technology, in particular to a method based on deposition and CO 2 Drive-consolidated artificial stone and method for its preparation. Background technique [0002] The existing artificial stone is mainly divided into two categories: organic artificial stone and inorganic artificial stone. Organic artificial stone uses resins such as unsaturated polyester or polymethyl methacrylate as adhesives, adding various fillers, pigments, curing agents and initiators, etc., and is prepared by stirring, molding, curing, cutting and polishing. become. Inorganic artificial stone is mainly prepared by using cement as a binder, adding stone powder and other inorganic fillers, and is prepared through processes such as stirring, molding, curing, cutting and polishing. The weather resistance of organic artificial stone is poor, and the organic components contained make it less environmentally friendly; the flexur...
