Description

Integrated board with thermal insulation, sound insulation and decorative functions

Technical field

The invention relates to the technical field of thermal insulation building materials, in particular to an integrated board which integrates fireproof soundproofing and decorative functions.

Background technique

In recent years, in the field of building wall materials, integrated boards integrating heat preservation and decorative functions have been widely used. At present, most of the insulation boards used on the market are organic boards such as polystyrene board, extruded board or polyurethane board. However, the above organic plate is easy to burn, and toxic gas is generated after combustion. Therefore, the heat-insulating integrated plate made of the organic plate has low fireproof rating and poor safety. Although, there are also thermal insulation integrated boards composed of foamed thermal insulation boards, rock wool boards, vitrified micro-beads or aluminum silicate fiber boards, etc., but the thermal conductivity of such inorganic insulation boards is high. The density is relatively large, and in order to achieve the desired insulation effect, it is necessary to additionally increase the thickness of the insulation layer. If the thermal insulation integrated board made of the above inorganic thermal insulation board is used for exterior wall construction, the number of building layers suitable for such materials is greatly limited. Aerogel has the characteristics of large specific surface area, high porosity, good acoustic properties, low density and low thermal conductivity. Therefore, it has great application potential in super insulator, high energy physics, high efficiency catalyst, sound insulation and energy storage materials. In addition, with its good insulation, fire and sound insulation properties, aerogel insulation felts and aerogel insulation boards play an increasingly important role in building insulation. The Chinese invention patent application with the application number 201310009065.8 applies for an integrated manufacturing method of aerogel insulation board decoration. Although the aerogel integrated board obtained by the method has the advantages of good heat preservation property and aging resistance, the method will be aerogel. The insulating layer is sandwiched between the reinforcing plate and the decorative plate, and the obtained aerogel insulated decorative integrated plate is heavy and costly.

Therefore, the current integrated board still needs to be improved.

Although, there are also thermal insulation integrated boards composed of foamed thermal insulation boards, rock wool boards, vitrified micro-beads or aluminum silicate fiber boards, etc., but the thermal conductivity of such inorganic insulation boards is high. The higher density will greatly limit the number of building layers that are suitable for such materials.
