Fire retardant panel for decoration

Abstract

The invention discloses a fire retardant panel for decoration. The fire retardant panel comprises a core material and fabric surfaces arranged on the two surfaces of the core material, the outer surface of each fabric surface is provided with a fire retardant layer, and each fire retardant layer is prepared from, by weight, 1-2 parts of sodium pyrophosphate, 3-4 parts of organic silicone oil, 2-3 parts of zinc sulfide, 1-2 parts of citric acid, 3-4 parts of 2-methyl-2-propenoic acid cyclohexyl ester, 2-3 parts of tellurium dioxide, 1-2 parts of barium sulfate, 3-4 parts of ammonium sulfate, 2-3 parts of pentachlorodiphenyl, 2-3 parts of magnesium hydrate and 3-4 parts of kieselguhr. The fire retardant panel for decoration has the advantages that the fire retardant panel has both good heat insulation performance and good fireproof performance, which effectively solves the problem that the heat insulation performance and the fireproof performance of the existing thermal materials cannot coexist; the fabric surfaces supply shock resistance, waterproof and anti-leakage performance and anti-cracking ability needed by the core material to the core material; the overall fireproof performance of a wall body thermal system is improved.

Description

technical field [0001] The invention relates to the technical field of decorative boards, in particular to a flame-retardant board for decoration. Background technique [0002] The current wall insulation materials mainly include molded expanded polystyrene board (EPS), extruded polystyrene board (XPS), polyurethane (PU) and other organic insulation boards and insulation mortars. Although the thermal conductivity of organic thermal insulation materials is low, their fire safety performance is generally poor. The non-combustibility can only reach B1 level, and toxic and harmful gases are easily produced during the combustion process. Once a fire occurs, it often causes heavy casualties and property. loss. Among the organic insulation materials, EPS and XPS melt and drip when exposed to fire, which is likely to cause the spread of fire. XPS has been controversial since its birth. Problems such as high strength, poor air permeability, difficult bonding, and poor dimensional s...

AI Technical Summary

Problems solved by technology

It is mainly manifested in the cracking of the insulation layer, poor thermal insulation performance, expansion and high dry density, etc. The thermal conductivity of the slurry is much higher than the standard value, and the energy saving effect that can be achieved is limited.

As far as vitrified microbead thermal insulation slurry is concerned, expanded perlite is often used instead of vitrified microbeads in practical applications. Due to its poor strength, it is easily broken when stirred, resulting in high dry density of vitrified microbead thermal insulation slurry and solidification of the slurry. After that, the expansion of water absorption is very easy to cause damage, these factors have greatly affected the thermal insulation performance of the slurry

In short, due to its own shortcomings such as high water absorption, high thermal conductivity, and easy hollowing and cracking, the application of inorganic vitrified microbead insulation mortar in cold regions has been limited, especially because the quality of on-site construction is difficult to control.
