Diatom-containing ecological brick and production method thereof

Abstract

The invention discloses a diatom-containing ecological brick and a production method thereof. The diatom-containing ecological brick is prepared from the following raw materials in parts by weight: 20-50 parts of diatomaceous earth, 1-3 parts of composite catalyst, 1-3 parts of nano-silver antibacterial agent, 10-30 parts of lithium feldspar, 10-30 parts of albite, 10-30 parts of wollastonite, 1-5 parts of pigment, 10-26 parts of 30% sodium silicate water solution adhesive and 4-12 parts of water. The raw materials are prepared into a finished product by the processes of dry-mixing, wet-mixing, pelleting, drying, compression moulding, drying, firing, cooling, checking and the like. The product provided by the invention is made from pure inorganic materials, and does not easily mold; the diatom-containing ecological brick is laid onto a wall by a dry method during construction, thus being convenient in construction, short in period, high in efficiency and low in cost; compared with a diatom ooze-containing decoration wall material, the strength and water resistance of the diatom-containing ecological brick are remarkably improved, and the service life of the diatom-containing ecological brick is remarkably prolonged.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a diatom ecological brick with diatomaceous earth, a composite catalyst and a nano-silver antibacterial agent as main functional components and a production method thereof. Background technique [0002] With the improvement of people's living standards and the enhancement of environmental protection and health awareness, the requirements for decoration materials are getting higher and higher. Traditional interior wall decoration materials are mainly latex paint and wallpaper. Although the development of technology has greatly improved the environmental protection performance, it still contains about 5% volatile organic compounds (VOC), which will affect the atmospheric environment and indoor environment. cause greater harm. Ordinary ceramic wall tiles pay attention to decoration such as color, texture, pattern, etc., especially glazed wall tiles, which close the mic...

AI Technical Summary

Problems solved by technology

[0003] The diatom mud decorative wall materials that have emerged in recent years are harmless in themselves and have ecological functions such as breathing, humidity control and air purification. However, there are still long construction periods, high construction costs, and poor construction skills due to the wet method of wall-mounting. At the same time, the strength, water resistance, moisture absorption and desorption performance, air purification performance, antibacterial and mildew resistance performance, and material service life of diatom mud decorative wall materials also have certain limitations.
