Abstract

The invention relates to a preparation method of pleonaste-containing artificial stone. The nano magnesia alumina spinel MgAl2O4 has the special structure, and can be added into talcum powder / phenolic resin / quartz as a high-grade inorganic nano oxide material to enhance the heat resistance and strength of the artificial stone and shorten the aging time of the artificial stone. The nano magnesia alumina spinel MgAl2O4 can keep undegraded for a long time under the action of high temperature, can keep favorable flame-retardant effects, increases the carbon residue quantity, and greatly enhances the LOI (loss on ignition) 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...
