Abstract

The invention relates to a preparation method of a flame-retardant artificial stone containing nano perovskite oxide MTiO3. The nano perovskite oxide and a metal organic framework ZIF material are jointly added into a ternary polyene ester material (such as talcum powder, quartz and phenolic resin), therefore, the heat resistance and the strength of the artificial stone are improved, the aging time of the artificial stone is shortened, the artificial stone can not be degraded for a long time under the high temperature action, the good flame-retardant effect can be kept, and the loss-on-ignition (LOI) index is significantly increased.

Description

technical field [0001] The present invention relates to a kind of nano-perovskite oxide MTiO 3 The invention discloses a method for preparing flame-retardant artificial stone, 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 wide...
