Abstract

The invention discloses a preparation method of a photocatalytic magnesium cementing material, and a product thereof. The photocatalytic magnesium cementing material comprises the following components in parts by weight: 100 parts of magnesium oxide powder, 120-125 parts of a blender, 8-12 parts of a filler, 6-10 parts of natural fiber, 5-7 parts of perlite, 2.6-2.9 parts of titanium dioxide, 3-5 parts of a foaming agent and 0.5-32 parts of a photocatalyst. By adding the photocatalyst, the magnesium cementing material is endowed with environment purification and self-cleaning functions, a composite building material plate with new functions can be prepared, and good creativity is achieved. Besides, the preparation method of the photocatalytic magnesium cementing material is simple, and the prepared photocatalytic magnesium cementing material has the advantages of low energy consumption, thorough reaction, capability of realizing complete mineralization of organic matters, no secondary pollution, wide application range and very good development prospect and market value, and can be used for manufacturing floors, wallpaper and the like.

Description

technical field [0001] The invention relates to a method for preparing a photocatalyzed magnesia gelling material and a product thereof. Background technique [0002] With the improvement of people's material living standards, various organic polymers are widely used in daily life, such as interior decoration materials, electrical products, daily chemicals, etc., resulting in increasing indoor air pollution. As a result, air pollution is also increasing, and indoor air pollution and health have become an important environmental issue of public concern. Due to the relatively closed indoor environment, volatile organic compounds (Volatile Organic Compounds, VOCs) slowly released by various materials accumulate and release slowly indoors, resulting in an increase in the concentration of VOCs in the indoor air, causing people to suffer from VOCs pollution. Indoor VOCs mainly come from the release of decoration materials, smoking, human activities, living fuel combustion, odor s...
