Flexible face brick with air purification function and preparation method thereof

Abstract

The invention discloses a flexible face brick with an air purification function and a preparation method thereof. The flexible face brick comprises a flexible face brick body and a self-cleaning coating, wherein the self-cleaning coating comprises the following components: 20-40 parts of a modified acrylate emulsion, 15-35 parts of nano TiO2 hydrosol and 15-35 parts of nano SiO2 hydrosol; and the flexible face brick body comprises the following components: 8-15 parts of an emulsion, 5-10 parts of kaolin, 15-25 parts of heavy calcium carbonate powder, 5-20 parts of cement, 5-15 parts of anion powder, 40-50 parts of silica sand, 0.1-1 part of an inorganic pigment and 10-20 parts of water. The preparation method of the flexible face brick is simple, energy-saving and environment-friendly, and the prepared flexible face brick can continually release anions in a long-acting manner to effectively adsorb tiny particles, peculiar smell and toxic gases in air. Ttunnelhe peculiar smell and the toxic gases are decomposed under the photocatalysis action of nano TiO2 in the coating, and the coating has an excellent self-cleaning function. Therefore, the flexible face brick is an ecological building material with the air purification function and the decoration function.

Description

technical field [0001] The invention relates to the technical field of new building decoration materials, in particular to a flexible decorative brick with air purification function and a preparation method thereof. Background technique [0002] Smog is a mixture of fog and haze. When the humidity is high in the morning and evening, the composition of fog is more. When the humidity is low during the day, haze dominates, and the relative humidity is between 80% and 90%. Among them, fog is a natural weather phenomenon, and the water vapor in the air is dense. Although dust is used as condensation nuclei, it is generally non-toxic and harmless; the core substance of haze is smoke, dust and other substances suspended in the air. The relative humidity of the air is lower than 80%, and the color is yellow. The gas can directly enter and adhere to the lower respiratory tract and lung lobes of the human body, which is harmful to human health. The formation of smog weather is main...
