preparation example Construction

[0041] A second aspect of the embodiments of the present application provides a method for preparing artificial stone, comprising the following steps:

[0042] S10: Provide the raw material components in the artificial stone of the present application; S20: Mix the raw material components to obtain a slurry;

[0043] S30 The slurry is injected into the mold to perform the first curing treatment, and then the mold is demolded for the second curing treatment to obtain artificial stone.

[0044] In the method for preparing artificial stone provided by the embodiments of the present application, the raw material components are first mixed to obtain a slurry, then the slurry is injected into a mold for a first curing treatment, and a second curing treatment is performed after demoulding to obtain an artificial stone. The preparation process is simple to operate, can self-foam and expand with only one injection, and can be self-filled and formed without vibrating. Therefore, accord...

Abstract

The invention relates to the technical field of energy conservation and environmental protection, and provides an artificial stone which comprises the following components in percentage by weight: 50-80% of calcium carbonate-containing solid waste, 15-25% of acidic liquid and 5-25% of a modified reinforcing agent. The artificial stone provided by the invention contains 50-80% of calcium carbonate-containing solid waste and 15-25% of acidic liquid, part of the calcium carbonate-containing solid waste reacts with the acidic liquid to release carbon dioxide, so that the slurry is foamed and expanded to fill the whole mold, and the rest of the calcium carbonate-containing solid waste plays a role in skeleton and filling; 5-25% of the modified reinforcing agent reacts with the acidic liquid to generate a gelling substance with very high strength, so that rapid setting and hardening of the slurry are realized, self-foaming expansion and self-filling forming of the slurry can be realized without adding a foaming agent, a mold with any shape and structure can be customized according to actual application requirements, and batch production of artificial stones meeting the requirements can be realized.

Description

technical field [0001] The application belongs to the technical field of energy saving and environmental protection, and in particular relates to an artificial stone and a preparation method thereof. Background technique [0002] my country is the world's largest producer and consumer of building materials, and the building materials industry is one of the industries with larger carbon emissions. It is of great significance to take practical and effective measures to fully promote carbon emission reduction and achieve the goal of carbon peaking ahead of time. Limestone powder and paper-making white mud are by-products discharged from mineral processing and paper-making, respectively, while shell slag is the remains of marine organisms, and its main component is CaCO 3 Powder, low activity, difficult to directly form gelatinous substances. The same is the main component of CaCO 3 The marble, slate, etc. are high-quality natural stone and are widely used in high-end buildin...
