Description
Technical Field
The utility model relates to a heat preservation panel field specifically is a compound sandwich insulation board.
Background
In recent years, the nation is vigorously advocating energy conservation and emission reduction, and a series of relevant policies are implemented, so that how to realize efficient utilization of energy is an important way for saving energy. Under the background, the development of the high-efficiency and low-cost heat-insulating material can effectively save energy. The most demanding of the heat insulation materials at present is the building external wall heat insulation system.
The mature heat insulating material used in the external wall heat insulating system is an organic foaming material. Extruded polystyrene board (XPS) insulation is currently used in large quantities for wall insulation. However, as a common heat insulation material, the extruded polystyrene board has high strength, but relatively large heat conductivity coefficient, and needs to better meet the energy-saving requirement, and the thickness of the material is large, which increases the workload for field construction and later maintenance, and the extruded polystyrene board is flammable and has poor fire resistance.
The silica aerogel heat preservation felt has the characteristics of high porosity, large specific surface area, small density, low heat conductivity, good fireproof performance and the like, and has a wide development prospect in the field of heat preservation and insulation. However, the silica aerogel insulation blanket generally has the defects of low strength, soft material and the like, so that the silica aerogel insulation blanket is inconvenient for exterior wall construction.
SUMMERY OF THE UTILITY MODEL
For solving prior art's not enough, the utility model provides a compound sandwich heated board, it can carry out the complex with extruded polystyrene board and aerogel felt, full play advantage between them provides a density is little, thermal conductivity is low, intensity is high, the insulation material that fire behavior is good.
The utility model discloses a realize above-mentioned purpose, realize through following technical scheme:
the utility model provides a compound sandwich heated board, includes a pair of skin and sandwich layer, the skin is aerogel felt, the sandwich layer is extrusion molding polyphenyl heated board, the sandwich layer is located two between the skin, a plurality of flutings are seted up to sandwich layer two sides, it glues to glue between the skin of sandwich layer and both sides.
The slots on the two sides of the sandwich layer are arranged in a staggered manner.
The inside of the groove is coated with adhesive.
The outer layer and the sandwich layer are glued through a pressing process.
Contrast prior art, the beneficial effects of the utility model are that:
the utility model discloses a regard aerogel felt as skin, extruded polystyrene heated board as sandwich layer, produces a composite insulation board. Because the extruded polystyrene insulation board as the sandwich layer has low density, the weight of the board is reduced on the whole, the density of the whole board is reduced, and the aerogel felt is used as the outer layer, so that the whole fireproof performance of the board can be well improved, and the heat conductivity coefficient of the board is reduced. The combination of aerogel felt and extrusion molding polyphenyl heated board combines together the toughness of aerogel felt and the hardness of extrusion molding polyphenyl heated board, has improved the intensity of whole panel to a certain extent, makes this composite sheet material be applicable to the building outer wall insulation demand better.
Drawings
Fig. 1 is a cross-sectional view of the present invention.
Reference numerals shown in the drawings: 1. an outer layer; 2. a sandwich layer; 3. grooving; 4. and (3) an adhesive.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and specific embodiments. It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes or modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope defined in the present application.
As shown in fig. 1, a compound sandwich heated board, including a pair of skin 1 and sandwich layer 2, sandwich layer 2 is located two between the skin 1, skin 1 is the aerogel felt, sandwich layer 2 is extrusion molding polyphenyl heated board. A plurality of slots 3 are arranged on two sides of the sandwich layer 2, and the sandwich layer 2 is glued with the outer layers 1 on two sides. Through the opening of the slot, enough adhesive can be contained in the slot, so that the outer layer and the sandwich layer can be better bonded. Through the combination of outer aerogel felt and sandwich layer extrusion molding polyphenyl heated board, make the fire behavior of whole panel stronger, coefficient of heat conductivity is littleer, and intensity is higher, more can adapt to the heat preservation requirement of building outer wall.
Specifically, the slots 3 on both sides of the sandwich layer 2 are arranged in a staggered manner, so that the slots on both sides are prevented from being in the same position to reduce the strength of the sandwich layer.
Specifically, the inside of the slot 3 is coated with an adhesive. The adhesive is fully filled in the groove, so that the adhesion between the sandwich layer and the outer layer can be ensured.
Specifically, the outer layer 2 and the sandwich layer 3 are bonded through a pressing process. Through the pressing, the outer layer can be bonded with the sandwich layer more tightly.
Example 1:
in order to fully bond the aerogel felt and the extruded polystyrene insulation board, 3mm multiplied by 3mm open grooves are processed on two surfaces of the extruded polystyrene insulation board, the open grooves are uniformly arranged on any surface, and the open grooves on the two surfaces are arranged in a staggered manner. And rolling and coating an adhesive on two sides of the extruded polystyrene insulation board, fully coating the adhesive in the groove, and respectively adhering aerogel felts with certain thicknesses to two sides of the extruded polystyrene board. And placing the preliminarily bonded sandwich insulation board in a pressing machine for pressing for 6 hours to ensure the sufficient bonding of the aerogel felt and the extruded polystyrene board.
Example 2:
aiming at embodiment 1, in this embodiment the extruded polystyrene insulation board and the aerogel felt can be sequentially superposed on one side of the composite board in embodiment 1, so as to realize the composite board of aerogel felt-extruded polystyrene insulation board- · -aerogel felt, and achieve better insulation effect through the increase of the number of layers.
