Problems solved by technology

The advantage of this type of stone is that it does not contain volatile organic compounds that are harmful to the human body, and has strong heat resistance, fire resistance, and aging resistance. Poor staining, so it can only be used as low-grade decorative building materials

Abstract

Embodiments in the invention disclose an artificial stone. The artificial stone comprises a base material and an active material, wherein the base material comprises, by mass, 150 to 800 parts of aggregate, the active material comprises, by mass, 200 to 800 parts of a cross-linking agent, the aggregate is one selected from or a mixture of quartz sand, stone powder, tailing sand and glass powder, and the cross-linking agent is one selected from or a mixture of high-alumina cement, Portland cement and fly ash. The embodiments of the invention also disclose a preparation method for the artificial stone. The method comprises the following steps: weighing the base material and the active material in proportion and carrying out uniform mixing so as to obtain a main material; subjecting the main material to spreading in a mold with a spreading machine in the manner of mathematical modeling; vibrating and pressurizing the mold filled with the material so as to obtain a green body; soaking the green body in an induction solution; and subjecting the green body to maintenance, stacking and finishing so as to obtain the artificial stone. The prepared artificial stone has same appearance, structural configuration, physicochemical properties and the like compared with natural stone.

Description

technical field [0001] The invention relates to the field of artificial stone production, in particular to an artificial stone and a preparation method thereof. Background technique [0002] In the context of today's global economic integration, in the face of excessive exploitation of resources, as well as serious environmental pollution and environmental damage, low-carbon environmental protection is the key to sustainable development. At the same time, with the development of the national economy and the improvement of people's quality of life, the requirements for building decoration materials are also getting higher and higher. Among them, the application of stone is relatively extensive. Stone as a decorative material is generally divided into natural stone and artificial stone. At present, over-exploitation of natural stone has brought irreparable damage to the ecological environment, and high-grade natural stone is close to resource depletion, resulting in an extre...
