Abstract

The invention relates to a preparation method of an artificial stone containing magnesia-iron spinel. The nano-magnesium-aluminum spinel MgAl2O4 has a special structure and can be used as a high-quality inorganic nanometer oxide material added to talc powder / phenolic resin / In quartz, it can improve the heat resistance and strength of artificial stone, reduce the aging time of artificial stone, keep it from degrading under high temperature for a long time, and also maintain a good flame retardant effect, increase the amount of residual carbon, and greatly improve the LOI burning. Loss index.

Description

technical field [0001] The invention relates to a method for preparing artificial stone containing nano-magnesium-aluminum spinel, which belongs to the field of building materials. Background technique [0002] With the improvement of people's living standards and living conditions, the interior decoration industry is developing rapidly, and the amount of decoration building materials is huge. Among them, stone is one of the most commonly used and most basic building materials, widely used in floors, walls and The paving of the countertop. The mining cost of natural stone is high, the pollution is large, 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 it is more and more accepted by the market and users, and is widely used in cabinets, bathrooms, floors, and wa...
