Abstract

The invention discloses a preparation method of modified marble powder low-temperature sintering artificial stone. The method comprises the following steps that 1, marble powder is dried, then, a surface modifier, sodium carbonate, barium sulfate, tealeaf residues and cement are added for performing ball milling, and then mixing and stirring are performed to obtain modified marble powder; 2, coalash, kieselguhr, crosslinked rectorite, clay, zinc oxide and tourmaline powder are added into the modified marble powder and mixed and stirred to obtain a mixture; 3, the mixture is mixed with nanometer aluminum oxide, titanium dioxide and sodium carboxymethylcellulose are mixed, the mixture is subjected to compression molding and drying, then, low-temperature sintering under the temperature of 300-400 DEG C for 1-2 h, and the artificial stone is obtained. Marble is modified, the marble powder sintering temperature can be effectively lowered, and the preparation technology has the advantages of saving energy and being environmentally friendly; the marble powder is small in particle interval, and the artificial stone sintering density and mechanical strength can be remarkably improved.

Description

technical field [0001] The invention relates to the technical field of artificial stone, in particular to a method for preparing modified marble powder low-temperature sintered artificial stone. Background technique [0002] With the development of economy and society, the demand for decorative natural stone (mainly marble and granite) is growing rapidly, with an annual growth rate of more than 10%. The stone industry occupies an important position in the global economy. A large amount of waste is generated in the process of stone processing, which is mainly divided into two categories: one is scraps, and the other is waste stone powder. According to statistics, about 1 ton of stone waste is produced for every 2.5 tons of natural stone produced, that is, the waste rate of natural stone during processing is about 20-30%. A large amount of stone waste not only pollutes water sources and soil, but also is a waste of resources, which is not conducive to the sustainable developm...
