Abstract

The invention discloses a photocatalyst diatom-mud lightweight high-strength plate, composed of a base plate and a photocatalyst layer, wherein the base plate is coated with the photocatalyst layer. The photocatalyst diatom-mud lightweight high-strength plate has the advantages that the formula is scientific, so that production raw materials are various and compatible; the plate itself has no any pollution; air can be purified, and the formaldehyde purification performance can reach 92.5 percent; the persistence of a formaldehyde purification effect reaches 90 percent; the indoor humidity can be adjusted, so that moisture in the air is absorbed and stored under a wet condition, and is released under a dry condition, and therefore a breathing wall is formed; the service life is 30 years or more, the disadvantages of edge warping, falling off and fading are prevented, the effect of oxidation resistance is achieved, and the plate is always like new; the wall is self-cleaning and is free from production of static electricity, so that dust is not adsorbed; the effects of sound adsorption and noise reduction are achieved; the effects of heat insulation and energy saving are achieved, and the heat insulation performance of the plate is more than six times of that of cement and mortar; the effects of fire prevention and flame resistance are achieved, and a high temperature of 1300 DEG C can be tolerated; the color is soft, so that the eyes are difficultly fatigued; the 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 light-weight high-strength board of diatom mud with photocatalyst. 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 invented by the American OCF...
