Burn-free diatom ecological brick and production method thereof

Abstract

The invention discloses a baking-free diatomite ecological brick and a preparation method thereof. The baking-free diatomite ecological brick comprises the following raw materials in parts by weight: 20-50 parts of diatomite, 1-3 parts of a composite catalyst, 1-3 parts of a nano silver antibacterial agent, 30-50 parts of white cement, 1-3 parts of wood fiber, 10-30 parts of ground calcium carbonate, 10-30 parts of talcum powder, 0.1-0.3 part of HPMC, 1-5 parts of pigment and 30-90 parts of water. The baking-free diatomite ecological brick is produced by the processes of mixing the raw materials, slurrying, pouring, vibrating, maintaining, demolding, grinding, checking and packaging. Compared with the diatom ooze decoration wall material, the strength, the water resistance and the service life of the diatomite ecological brick are significantly improved; the baking-free diatomite ecological brick is convenient to construct, short in period and high in efficiency; the baking-free diatomite ecological brick is produced by taking an inorganic cementitious material as a base material through a pouring process; the baking-free diatomite ecological brick can be maintained and cured at the normal temperature; the process is simplified on the basis that the advantages of the diatomite ecological brick are retained; the energy consumption is reduced; the equipment investment and the construction investment are reduced.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a non-fired diatom ecological brick with diatomite and a composite catalyst 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 micro...

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.

However, diatom ecological bricks need to be fired at high temperature in the production process, and there is energy consumption and pollutant discharge in the production process.
