Description

Technical Field

[0001] This utility model relates to the field of extruded polystyrene board technology, specifically an extruded polystyrene board for building energy-saving insulation. Background Technology

[0002] In today's society, with the increasing prominence of energy issues and the growing attention paid to environmental protection and sustainable development, building energy conservation has become an important development direction for the construction industry. Building energy consumption accounts for a large proportion of total social energy consumption, and heat transfer through building wall structures is one of the main reasons for excessive building energy consumption. Currently, extruded polystyrene (XPS) boards, as a commonly used building wall insulation material, are widely used in the field of building energy conservation. They have a closed-cell honeycomb structure, which effectively prevents heat conduction and provides good thermal insulation performance. However, traditional XPS boards still have some shortcomings in practical applications.

[0003] On the one hand, the thermal insulation performance of traditional extruded polystyrene (XPS) boards still has room for improvement. In high or low temperature environments, heat will still be transferred through the boards, leading to significant fluctuations in indoor temperature and increasing energy consumption for air conditioning, heating, and other equipment. On the other hand, traditional XPS boards have relatively low strength. During construction and use, the boards are easily deformed or damaged by external forces, affecting insulation performance and building safety. Utility Model Content

The extruded layer and the reinforcing layer are bonded and fixed to each other on opposite sides, and a cavity structure is formed between the extruded layer and the reinforcing layer. The heat-insulating filling layer is filled in the cavity structure between the extruded layer and the reinforcing layer. An opening is formed on the side of the reinforcing layer facing away from the extruded layer. The reflective layer is embedded in the opening and bonded and fixed to the reinforcing layer.

[0008] Preferably, a plurality of fastening grooves are formed on the outer edge of the extruded layer facing the reinforcing layer, and a number of fastening blocks are formed on the outer edge of the reinforcing layer facing the extruded layer, which are equal in number and matched in shape to the number of fastening grooves, and each fastening block is inserted into an adjacent fastening groove.

[0009] In a further preferred embodiment, the extruded layer has a bottom receiving cavity on the side facing the reinforcing layer, and the reinforcing layer has a top receiving cavity on the side facing the extruded layer.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1 and Figure 2 An extruded polystyrene (XPS) board for building energy-saving insulation includes an extruded layer 10, a thermal insulation filling layer 20, a reinforcing layer 30, and a reflective layer 40. The XPS layer 10 and the reinforcing layer 30 are bonded and fixed to each other on opposite sides. A cavity structure is formed between the XPS layer 10 and the reinforcing layer 30, and the thermal insulation filling layer 20 is filled and disposed in the cavity structure between the XPS layer 10 and the reinforcing layer 30, thereby improving the overall thermal insulation capacity of the XPS board. An opening 35 is formed on the side of the reinforcing layer 30 facing away from the XPS layer 10, and the reflective layer 40 is embedded in the opening 35 and bonded and fixed to the reinforcing layer 30. The outer surface of the reflective layer 40 is coated with a heat-reflective coating. The coating may contain metal oxides (such as zinc oxide, titanium oxide, etc.) or metal particles (such as aluminum powder, etc.). When heat emitted from the room is radiated outward in the form of infrared rays, the heat-reflective coating on the reflective layer 40 can effectively reflect the heat back into the room, reducing heat loss from the building.

[0024] In this embodiment, the thermal insulation filling layer 20 is entirely made of aerogel material. Aerogel pads have extremely low thermal conductivity, lower than that of the extruded layer. The aerogel pad can effectively prevent heat transfer in both high and low temperature environments, providing excellent thermal insulation. In addition, it also has good fire resistance and a certain degree of sound insulation.

[0025] See Figures 3 to 5 The extruded layer 10 has several fastening grooves 11 formed on its outer edge facing the reinforcing layer 30, and the reinforcing layer 30 has fastening blocks 31 of the same number and shape as the fastening grooves 11 formed on its outer edge facing the extruded layer 10. During assembly, each fastening block 31 can be inserted into an adjacent fastening groove 11, ensuring that the outer edges of the extruded layer 10 and the reinforcing layer 30 are flush and aligned.

[0026] A bottom receiving cavity 12 is formed on the side of the extruded layer 10 facing the reinforcing layer 30, and a top receiving cavity 32 is formed on the side of the reinforcing layer 30 facing the extruded layer 10. The bottom receiving cavity 12 and the top receiving cavity 32 together form a cavity structure for receiving the heat insulation filling layer 20, allowing the heat insulation filling layer 20 to be filled and disposed between them. A plurality of bottom slots 13 arranged in an array are formed on the inner bottom wall of the bottom receiving cavity 12, and a plurality of top slots 33 arranged in an array are formed on the inner top wall of the top receiving cavity 32. Protrusions 21 that can be inserted into the bottom slots 13 and the top slots 33 are formed on both opposite sides of the heat insulation filling layer 20, so that the heat insulation filling layer 20 can also be positioned when filled and disposed between the extruded layer 10 and the reinforcing layer 30.

[0027] In this embodiment, the reinforcing layer 30 is configured as an integral injection-molded structure, which can effectively withstand external forces and reduce problems such as deformation and damage to the sheet material.

[0028] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as bonding, welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, bonding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
