Lightweight and sun-proof heat insulation board for decorating

Abstract

The invention discloses a lightweight and sun-proof heat insulation board for decorating. The lightweight and sun-proof heat insulation board for decorating comprises a core material, and woven fabric surfaces which are arranged on two surfaces of the core material, wherein a polymer mortar layer is arranged on the outer surface of each woven fabric surface; the polymer mortar layers are prepared through the following mortar in parts by weight: 200 to 250 parts of cement, 500 to 550 parts of glass beads, 50 to 80 parts of heavy calcium carbonate powder, 20 to 30 parts of redispersible emulsion powder, 2 to 4 parts of water-retaining agent, 0.5 to 1 part of antifoaming agent, 1 to 2 parts of polypropylene fiber, 2 to 3 parts of water repellent, and 200 to 250 parts of water; the core material is a waterproof rock wool heat insulation board. The lightweight and sun-proof heat insulation board for decorating has the beneficial effects that the heat preservation and insulation performances are outstanding; the fireproofing performance is high; the woven fabric surfaces enable the impact resistance, the fireproofing and anti-penetrability performances and the cracking resistance of the core material, so that the defects that general inorganic heat insulation boards are poor in waterproofing performance and low in surface intensity can be overcome.

Description

technical field [0001] The invention relates to the technical field of thermal insulation materials, in particular to a light-weight sun-proof thermal insulation 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, diffic...

AI Technical Summary

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.
