Problems solved by technology

The main manifestations are 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, water absorption and expansion can easily cause damage, and these factors have greatly affected the thermal insulation performance of the slurry.
In short, the application of inorganic vitrified microbead thermal insulation mortar in cold regions has been limited due to its own shortcomings such as high water absorption, high thermal conductivity, and easy hollowing and cracking, especially the difficulty in controlling the quality of on-site construction.

Abstract

The invention discloses a light-weight thermal 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 composed of mortar which is prepared from, by weight, 30-40 parts of a polyurethane prepolymer, 2-4 parts of dibutyl phthalate, 0.5-1 part of a coupling agent of organic titanate, 3-5 parts of talcum powder, 3-5 parts of light calcium carbonate, 0.1-0.5 part of tributyl phosphate, 0.5-1 part of isopropyl alcohol, 10-15 parts of a mixed solvent and 3-5 parts of a fire retardant material, wherein the core material is a waterproof rock wool thermal plate. The light-weight thermal fire retardant panel for decoration has the advantages that the fire retardant panel has both good heat insulation performance and good fireproof performance; the fabric surfaces supply shock resistance, waterproof and anti-leakage performance and anti-cracking ability needed by the core material to the core material, and the shortcomings of poor waterproofness and low surface strength of normal inorganic thermal plates are overcome.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a light thermal insulation and 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 will melt and drip in case of fire, which may easily cause the spread of fire. XPS has been controversial since its birth. Problems such as high strength, poor air permeability, dif...
