Abstract

The invention discloses a method for manufacturing a photocatalyst diatom ooze light high-strength plate.The photocatalyst diatom ooze light high-strength plate is composed of a base plate and a photocatalyst layer applied to the base plate.The formula is scientific, and compatibility of various production materials is realized.The photocatalyst diatom ooze light high-strength plate can not cause pollution.By the adoption of the photocatalyst diatom ooze light high-strength plate, air purification can be achieved, formaldehyde purification performance can reach 92.5%, and formaldehyde purification effect durability can reach 90%; indoor moisture can be adjusted, moisture in air can be absorbed and stored under the moist condition, and moisture can be released under the dry condition; in this way, a breathable wall is obtained.The service life of the photocatalyst diatom ooze light high-strength plate is over 30 years, edge warping, falling off and fading are avoided, oxidation resistance is high, and the photocatalyst diatom ooze light high-strength plate can stay new for a long time.Self-cleaning of a wall is realized, and static electricity is not generated so that dust adsorption can be avoided.Sound insulation and noise reduction are realized.Heat insulation and energy conservation are realized, and heat insulation property is over 6 times that of cement and mortar.The photocatalyst diatom ooze light high-strength plate is resistant to fire and inflaming and can resist temperature as high as 1300 DEG C.The photocatalyst diatom ooze light high-strength plate has a soft color and can avoid eyestrain.The photocatalyst diatom ooze light high-strength plate is widely applied to architectural decoration and industrial equipment.

Description

technical field [0001] The invention belongs to the technical field of building materials, and relates to a method for preparing a light-weight high-strength board made of photocatalyst diatom mud. Background technique [0002] At present, in the field of building materials, there are many kinds of building materials with fireproof and thermal insulation functions. Inorganic fireproof and thermal insulation rock mud is one of them. The inorganic fireproof and thermal insulation rock mud is cement, bentonite, flocculent iron fiber short filaments, glass fiber short filaments, foam stone particles, kerogen shale particles, hydrophobic perlite particles mixed with water to form a plastic slurry, which can cement sand and gravel and other materials. The powdery hydraulic cementitious material hardened in air and water can be used for the inner and outer walls of buildings. [0003] Calcium silicate board is another one of them. Calcium silicate board is a building board inven...
