Problems solved by technology

[0003] The mining cost of natural stone is high, the pollution is high, and it contains a large amount of natural radioactive substances, which is harmful to human health. With the continuous development of the material field, the performance of artificial stone has gradually improved, approaching or even surpassing natural stone, and is becoming more and more popular in the market. Accepted by users, but the current artificial stone still has the disadvantages of low strength and poor surface pollution resistance, which needs further improvement

preparation example Construction

[0045] A preparation method of high-hardness artificial stone, comprising the following steps:

[0046] Step 1, removing powder and impurities in the aggregate and powder;

[0047] Step 2, weighing the aggregate, powder, pigment, and dispersant by weight, mixing, and stirring evenly, then adding resin, and continuing to stir evenly;

[0048] Step 3, put the mixed material stirred in step 2 into the cloth mold frame;

[0049] Step 4, transfer the cloth mold frame to the press equipment, and carry out vibration pressing under the vacuum condition of (-0.1) MPa;

[0050] Step 5, after the pressing is completed, the mold is demoulded, and the blank is sent to a curing furnace, and kept at a temperature of 80-110°C for 20-30 minutes to cure and form;

[0051] Step 6, after the blank is solidified, it is cooled to room temperature after 24 hours, and then enters the thickness-setting equipment for thickness-setting;

[0052] Step 7, after the thickness setting is completed, enter...

Abstract

The invention relates to a high-hardness artificial stone and a preparation method thereof, and the high-hardness artificial stone comprises the following raw materials: aggregate, powder, resin, pigment and a dispersant. The aggregate is prepared from the following raw materials: quartz sand and waste glass; and the powder is prepared from kiln furniture waste, mullite powder, boric sludge, kieselguhr and basalt fiber. The specific compositions of the artificial stone are limited, the quartz sand and the waste glass are used as main materials, and the powder and the resin are added, so that the prepared artificial stone has the advantages that the Mohs hardness can reach 7, the surface pollution resistance is good, the glossiness is high, the density is small, the radionuclide limit meets the requirements of A-class decoration materials in the standard GB6566-2010, and it is guaranteed that the use range of the artificial stone is not limited.
