Technical Field
The utility model belongs to the field of building materials, and particularly relates to a foamed ceramic decorative heat-insulation integrated plate.
Background
The heat-insulating and decorating integrated plate is a heat-insulating and decorating system arranged on the surface of a building wall, and has the advantages of excellent heat-insulating effect, long term, less heat bridge effect and good energy-saving and heat-insulating effects. Is composed of adhesive layer, insulating layer, finished decorative plate and sealing material. The construction schemes are numerous, and the method is not only suitable for the heat preservation and decoration of the outer wall of a new building, but also suitable for the energy conservation and decoration transformation of an old building; the heat insulation board is suitable for various public buildings and external wall external heat insulation of residential buildings; the building is suitable for buildings in cold areas in the north and buildings in hot areas in the south. Compared with the traditional energy-saving heat-insulating construction process, the heat-insulating and decorating integrated plate has more and better heat-insulating functions.
The fire resistance of the heat-insulating layer of the existing heat-insulating and decorating integrated plate is the key of the whole fire resistance, and how to improve the fire resistance and the flame retardance of the heat-insulating layer is of great importance.
SUMMERY OF THE UTILITY MODEL
The utility model aims to enhance the fireproof and flame-retardant performance of the heat-insulation and decoration integrated plate.
In order to solve the above problems, a foamed ceramic decorative heat insulation integrated board is proposed, which includes an interface layer fixed to a surface of a building, a heat insulation layer connected and fixed to the interface layer, an adhesive layer for adhesion, and a foamed ceramic glaze layer fixed to the heat insulation layer through the adhesive layer.
The heat-insulating layer is internally provided with a flame-retardant partition for enhancing the fire-proof performance, the continuity of the heat-insulating layer is reduced through the flame-retardant partition, and a firewall effect is formed inside the flame-retardant partition so as to effectively block or greatly reduce the diffusion speed of combustion inside the heat-insulating layer.
The flame-retardant partition is a multi-layer flame-retardant structure formed by arranging horizontal grooves in a staggered manner on two side surfaces of the heat-insulating layer and pouring cement mortar. The fire-retardant wall adopts crisscross level setting can effectively eliminate when the heat preservation burns the inside chimney effect that forms the intensity of a fire and scurries upward of heat preservation decoration intergral template, and then is showing the improvement the fire prevention fire behavior of heat preservation decoration intergral template.
Further, the flame-retardant partition can also be embedded in the heat-insulating layer by adopting other flame-retardant materials to achieve the same fireproof flame-retardant effect, for example, a foamed ceramic plate or a cement plate is used instead of being poured by cement mortar to form the flame-retardant partition.
The horizontal width of the flame-retardant partition is 60% -90% of the thickness of the heat-insulating layer, so that a heat bridge is prevented from being formed at the flame-retardant partition on the basis of ensuring the flame-retardant effect, and further, the heat-insulating performance of the heat-insulating decorative integrated plate is prevented from being reduced.
The interface layer is an interfacial agent or polymer mortar composite glass fiber.
The heat-insulating layer is a rock wool, silicon-aluminum based fireproof heat-insulating plate or an isolated nano-plastic graphite extruded plate.
The bonding layer is adhesive or bonding mortar.
The foaming ceramic glaze layer comprises a foaming ceramic plate and a glaze layer on the outer surface of the foaming ceramic plate.
The nano-plastic graphite extruded sheet has a fire-resistant grade A and a thermal conductivity of 0.025.
The fireproof performance of the foamed ceramic plate reaches the fire-resistant grade A, and the heat conductivity coefficient of the foamed ceramic plate is 0.06-0.10.
And a decorative pattern printing layer is arranged between the glaze layer and the foaming ceramic plate.
The side surface of the foamed ceramic decorative heat-insulation integrated plate is circumferentially sealed by adopting fireproof paint, so that the continuity of the heat-insulation layer on a building wall is damaged, and the flame-retardant and fireproof performance of the decorative heat-insulation integrated plate is further enhanced.
In conclusion, the utility model reduces or destroys the continuity of the heat-insulating layer on the wall of the building through the structural innovation, thereby obviously improving the fireproof and flame-retardant performance.
