Description

Composite insulation board with inorganic material coated with organic material

technical field

The utility model relates to the structural design category of a building thermal insulation composite board, in particular to a composite thermal insulation board in which an inorganic material is coated with an organic material.

Background technique

With the continuous improvement of building energy-saving standards, in order to meet the thermal insulation requirements of buildings, thermal insulation treatment of building exterior walls has become a commonly used energy-saving method in building energy conservation. Commonly used external wall insulation materials are mostly lightweight organic materials such as polystyrene boards and polyurethane foam boards, which not only have problems such as low strength, poor bonding ability with the base wall, poor durability, and prone to swelling and cracks during construction. , more importantly, there are fire safety hazards.

At present, the hidden fire hazard of external wall insulation has attracted widespread attention, and it is imperative to improve the fire performance of external wall insulation system. In order to improve the fireproof performance and strength of the organic insulation board, it is now widely used to cover the inorganic protective layer such as cement polymer mortar or brushing interface mortar on the outside of the organic insulation board in different ways. The strength of the board also improves its fire performance. However, since the polymer mortar is a heavy non-insulation material, the thickness of the compound with the organic insulation board should not be too thick, otherwise the composite insulation board will have a larger bulk density and a lower insulation effect. Problem; In case of fire, the polymer mortar protective layer will quickly transfer heat to the organic insulation layer, which itself will cause problems of cracking and falling off.

Utility model content

The purpose of the utility model is to solve the problem that the current composite thermal insulation board has a large bulk density, a decrease in thermal insulation effect, and cracking and falling off of the polymer mortar protective layer in case of fire.

A kind of composite thermal insulation board with inorganic material coated organic material designed by the utility model is composed of an inorganic material thermal insulation layer (1) and an organic material core board (2), that is, six sides of the organic material core board are provided with inorganic material thermal insulation layers (see Figure 1). The inorganic material insulation layer (1) is foamed cement, foam concrete, inorganic insulation mortar, foam ceramic board, foam glass board or expanded vitrified bead board; the organic material core board (2) is polyurethane foam board, Phenolic foam board, molded polystyrene foam board, or extruded polystyrene foam board. According to needs, the composite thermal insulation board with inorganic materials coated with organic materials can be designed to cover the front, back and both sides of the core board of organic materials, or it can be designed to cover the front and back of the core board of organic materials.

The composite method of the composite thermal insulation board with inorganic materials coated with organic materials is as follows: use foamed cement, foam concrete or inorganic thermal insulation mortar to cover and pour the organic material core board to make it composite with the organic material core board; Foamed cement boards, foamed concrete boards, foamed ceramic boards, foamed glass boards or expanded vitrified bead boards are bonded and compounded with organic material core boards.

A composite thermal insulation board with inorganic materials coated with organic materials designed by the utility model combines the advantages of high strength and good fireproof performance of inorganic thermal insulation materials and good thermal insulation and light weight of organic thermal insulation materials, and overcomes the large volume and low weight of inorganic thermal insulation materials. The defect of poor fire resistance of organic thermal insulation materials gives full play to the advantages of both. A new type of composite insulation board is designed and manufactured by combining inorganic insulation materials and organic insulation materials, which is easy to cut on site, has strong adaptability, is easy to construct, and can meet the requirements of building insulation and fire protection.

Since the inorganic thermal insulation material is a lightweight and porous thermal insulation material, according to the fire resistance limit requirements of individual projects, the thickness of the inorganic thermal insulation mortar can be designed to be more than 10mm, and when it is combined with the organic thermal insulation board, the bulk density of the composite thermal insulation board will not increase too much. In the event of a fire, the porous structure of the inorganic thermal insulation material will significantly reduce the heat transfer rate, so that a large amount of combustion heat will not reach the interior of the organic thermal insulation board in a short time, ensuring the fire resistance of the composite thermal insulation board, and at the same time ensuring the thermal insulation performance of the composite thermal insulation board.

In terms of construction, according to the existing mature construction technology of external wall thermal insulation system, the installation and construction can be carried out in the way of bonding and anchoring. Not only the construction process is simple, but also easy to operate. The inorganic thermal insulation material is a cement-based material, which is bonded to the base wall. It is strong, and it can also effectively solve the problems of plate falling off and cracking, and the construction quality is guaranteed. The composite thermal insulation board designed by the utility model, in which an inorganic material is coated with an organic material, can be used for external wall thermal insulation, and can also be used for roof thermal insulation and ground thermal insulation.
