Diatom plate and production method thereof

Abstract

The invention discloses a diatom plate and a production method thereof. The diatom plate is composed of, by weight, 30-60 parts of diatomite, 0.5-1.5 parts of nano titanium dioxide, 0.01-0.1 part of nano silver antibacterial agent, 15-25 parts of slaked lime, 5-10 parts of paper pulp fiber, 0-30 parts of cement, 1-5 parts of hemihydrate gypsum, 0.1-20 parts of quartz powder, 0.1-0.3 part of pigment and 400-900 parts of water. The diatom plate has the advantages that compared with wood, the diatom plate is richer in resource, higher in resource utilization rate and more environment-friendly andhas air purifying, bacteria resisting and mildew preventing functions that the wood does not have; compared with a fiber plate, the diatom plate does not contain harmful substances like formaldehyde,benzene, methylbenzene, xylene and VOC; compared with gypsum plates, the diatom plate is higher in strength and better in water resistance; compared with diatom ooze decoration wall materials, the diatom plate is supportive of integrated decoration, high in construction efficiency, low in labor cost and less in construction pollution; compared with diatom ecological bricks, the diatom plate is lower in material cost and higher in construction efficiency.

Description

technical field [0001] The invention relates to the technical field of decorative materials, in particular to a diatom board with diatomite, nano-titanium dioxide and nano-silver antibacterial agent as main functional components and a production method thereof. Background technique [0002] Air pollution and interior decoration lead to indoor air pollution. The prevention and control of indoor air pollution should adopt the methods of source control and comprehensive treatment. Selecting environmental protection and ecological environment materials for interior decoration is an effective way to reduce and control indoor air pollution. Wood is a natural and environmentally friendly material that is popular with people, but its resources are limited; fiberboards produced from fast-growing forests and crop straw plant fibers, due to the use of organic adhesives or high-molecular polymers as bonding components, are in use. Formaldehyde, benzene, toluene, xylene, VOC and other ...

Problems solved by technology

Wood is a natural and environmentally friendly material that is popular with people, but its resources are limited; fiberboards produced from fast-growing forests and crop straw plant fibers, due to the use of organic adhesives or high-molecular polymers as bonding components, are in use. Formaldehyde, benzene, toluene, xylene, VOC and other harmful substances will be released during the process; as an environmentally friendly building material, gypsum board is widely used in interior decoration, but gypsum board has low strength, poor water resistance, and does not have ecological functionality; silicon Algae mud decorative wall materials and diatom ecological bricks do not contain harmful substances such as formaldehyde, benzene, toluene, xylene, VOC, and water-soluble heavy metals, and have ecological functions such as breathing adjustment, air purification, antibacterial and mildew resistance, but, due to silicon The algae mud decorative wall material is applied on the wall by wet method, which is handmade, has low construction efficiency and high labor cost, and is not suitable for the construction needs of large projects. Due to the firing process of diatom ecological bricks, the energy consumption is high, the cost is also high, and the size is also large. Small, construction also has certain limitations
