Embodiment 1

[0019] (1) Preparation of composite magnesium iron spinel MgAl 2 O 4 :

[0020] (a) MgAl 2 O 4 Preparation: Weigh 0.02molMg(NO 3 ) 2 · 6H 2 O, 0.04molAl(NO 3 ) 3 ·9H 2 O is dissolved in 50ml of deionized edema to prepare a mixed salt solution. Dissolve 0.04mol of Na2CO3 and 0.06mol of NaOH in 50ml of deionized water, then quickly stir, add the salt solution to the alkaline solution, keep the pH at 9-11, mix well, The precipitate is filtered and washed with deionized water until neutral. Dry in an oven at 80°C for 8 hours. Then roast in a muffle furnace at 800°C for 4-6h.

Abstract

The invention relates to a preparation method of flame-retardant artificial stone containing pleonaste. Nano magnesium aluminate spinel MgAl2O4 has a special structure and can serve as a high-quality inorganic nano oxide material to be added to talcum powder/phenol-formaldehyde resin/quartz, the heat resistance and the strength of the artificial stone are improved, the ageing time of the artificial stone is shortened, the flame-retardant artificial stone can be prevented from being degraded at the high temperature for a long time, a better flame retardant effect can be kept, the quantity of carbon residues is increased, and the LOI (loss on ignition) index is greatly increased.

Description

Technical field [0001] The invention relates to a method for preparing a flame-retardant artificial stone containing nano-magnesium-aluminum spinel, and belongs to the field of building materials. Background technique [0002] With the improvement of people’s living standards and the improvement of 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 one of the most basic building materials, which is widely used on the ground, wall and The paving of the countertop. Natural stone has high mining costs, high pollution, and 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 that of natural stone, and is increasingly accepted by the market and users, and is widely us...
