Abstract

The invention belongs to the technical field of fireproof plates, and particularly relates to a flame-retardant heat-insulation magnesium-silicon fireproof plate and a manufacturing method thereof. Aiming at the problem of poor heat insulation effect of a fireproof plate in the prior art, the invention provides a flame-retardant heat-insulation magnesium-silicon fireproof plate and a manufacturingmethod thereof, and the flame-retardant heat-insulation magnesium-silicon fireproof plate comprises a PVC base layer and a magnesium-silicon fireproof layer arranged on the PVC base layer, and the magnesium-silicon fireproof layer comprises magnesium oxide, quartz sand, nano montmorillonite, silicon carbide, a magnesium sulfate aqueous solution, alkali-free glass fiber cotton, clay powder and a pore-foaming agent. The fireproof plate provided by the invention has better flame-retardant and heat-insulating effects, and can better isolate damage possibly caused by a fire when the fire occurs, so that the loss is reduced.

Description

technical field [0001] The invention belongs to the technical field of fireproof boards, and in particular relates to a flame-retardant and heat-insulating magnesium-silicon fireproof board and a manufacturing method thereof. Background technique [0002] At present, based on the consideration of fire safety in modern buildings and public places, various kinds of fireproof boards must be used in the decoration of public places such as civil residences, various hotels, office and commercial buildings at home and abroad. Most of the fireproof plates used in the prior art are metal plates with metal as the main material, such as stainless steel plates, galvanized plates, aluminum plates, etc. Although they have a flame retardant effect, their heat conduction effect is obvious and cannot be used for heat insulation. In the event of a fire, the damage caused by the fire cannot be completely isolated. [0003] In response to this problem, people have also carried out exploration ...
