Description

Technical Field

[0001] The utility model relates to the technical field of extruded boards, and more specifically, it relates to a composite extruded board. Background Art

[0002] Extruded Polystyrene (abbreviated as XPS) is a high-performance building insulation material produced from polystyrene resin through an extrusion process. With its excellent thermal insulation performance, high compressive strength, low water absorption, and good chemical stability, it is widely used in the field of building energy conservation. With the increasing requirements for building energy conservation, the technology of extruded boards has been continuously developed, and new products such as graphite extruded boards have emerged. On the basis of maintaining the original excellent performance, these new extruded boards further improve the fire resistance, thermal insulation performance, and compressive strength. With the continuous progress and innovation of technology, the application scope of extruded boards will be further expanded, contributing to the realization of green buildings and energy conservation and emission reduction goals.

[0003] At present, there are still some deficiencies in the shock absorption and sound insulation of existing extruded boards, and in the construction environment with relatively large dust or moisture, the surface of the extruded board is easily affected by the outside world, resulting in poor bonding between the wall and the extruded board; therefore, this application proposes a composite extruded board to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the existing technology, the utility model aims to provide a composite extruded board, which has good thermal insulation performance, and at the same time has functions such as sound insulation and shock absorption, and the surface is protected by release paper, which is convenient for construction.

[0005] To achieve the above object, the utility model provides the following technical solution: a composite extruded board, including an extruded board layer, an anti-cracking layer is arranged on the outer surface of one side of the extruded board layer, a cement mortar layer is arranged outside the anti-cracking layer, a shock absorption layer and a release paper layer are arranged on the other side of the extruded board layer, and a sound insulation layer is arranged between the extruded board layer and the shock absorption layer.

[0006] The utility model is further arranged as follows: an anti-cracking layer close to the extruded board layer and a cement mortar layer close to the sound insulation layer are arranged between the extruded board layer and the sound insulation layer.

[0007] The utility model is further arranged as follows: the cement mortar layer is made of ordinary cement mortar or thermal insulation cement mortar, and at least one thermal insulation material is mixed in the thermal insulation cement mortar.

[0008] The utility model is further arranged as follows: the thermal insulation materials include polystyrene particles, expanded perlite, and foam glass.

[0009] The utility model is further arranged as follows: the anti-cracking layer is arranged as a fiberglass mesh.

[0010] The present utility model is further configured such that: the shock-absorbing layer is made of butyl rubber or nitrile rubber.

[0011] The present utility model is further configured such that: the sound-insulating layer is made of rubber and plastic sound-insulating cotton.

[0013] The present utility model is further configured such that: the extruded polystyrene board layer is made of graphite extruded polystyrene board or XPS extruded polystyrene board.

[0014] The present utility model is further configured such that: the extruded polystyrene board layer is replaced by a polyurethane board.

[0015] In summary, the present utility model has the following beneficial effects:

[0016] The present utility model is provided with a crack-resistant layer to improve the crack-resistant strength of the composite extruded polystyrene board. At the same time, a sound-insulating layer is provided, preferably made of rubber and plastic sound-insulating cotton. By laminating the sound-insulating layer on the extruded polystyrene board, the sound-insulating and noise-reducing function is increased. Furthermore, a shock-absorbing layer is further added to strengthen the damping and shock-absorbing effect. Further, the present utility model also provides a release paper on one side to temporarily protect the board. Especially in a poor construction environment, such as a dusty environment or a humid environment, the release paper can keep the surface of the board from being contaminated and can also protect the surface from scratches and physical damage.

[0020] The following further describes the present utility model in detail with reference to the drawings.

[0021] This embodiment discloses a composite extruded polystyrene board, including an extruded polystyrene board layer 1. According to whether the extruded polystyrene board layer 1 has a crack-resistant layer 2 and a cement mortar layer 3 on one side or both sides, it is divided into two embodiments, as Figure 1-2 shown;

[0022] Embodiment 1: Refer to Figure 1, an anti-cracking layer 2 is provided on the outer surface of one side of the extruded board layer 1, a cement mortar layer 3 is provided on the outside of the anti-cracking layer 2, a shock-absorbing layer 4 and a release paper layer 5 are provided on the other side of the extruded board layer 1, and a sound-insulating layer 6 is provided between the extruded board layer 1 and the shock-absorbing layer 4.

[0023] Example 2: Refer to Figure 2 , on the basis of Example 1, an anti-cracking layer 2 close to the extruded board layer 1 and a cement mortar layer 3 close to the sound-insulating layer 6 are provided between the extruded board layer 1 and the sound-insulating layer 6, that is, anti-cracking layers 2 are provided on the outer surfaces of both sides of the extruded board layer 1, a cement mortar layer 3 is provided on the outside of the anti-cracking layer 2, a shock-absorbing layer 4 and a release paper layer 5 are provided on the outer surface of one of the cement mortar layers 3, and a sound-insulating layer 6 is provided between the cement mortar layer 3 and the shock-absorbing layer 4.

[0024] Through the above settings, the anti-cracking layer 2 improves the overall anti-cracking strength. The anti-cracking layer 2 is preferably set as a mesh cloth. The mesh cloth as the anti-cracking layer can effectively prevent cracks caused by temperature changes, humidity changes or mechanical loads, and can also improve the bonding strength between the extruded board and other substrates, ensuring the overall firmness of the board. This embodiment also provides a release paper layer 5, which can temporarily protect the board on one side of the shock-absorbing layer 4, preventing the surface of the board from being polluted, scratched and damaged, especially suitable for environments with large dust or high humidity. In such an environment, the surface of conventional boards is easily contaminated with dust and water droplets, and must be pre-cleaned before construction can continue. In this embodiment, the release paper can be torn off during construction to quickly carry out construction, saving time and improving construction efficiency.

[0025] Furthermore, in this embodiment, the cement mortar layer 3 can be flexibly selected to be made of ordinary cement mortar or thermal insulation cement mortar according to actual heat preservation needs. Among them, at least one thermal insulation material is mixed in the thermal insulation cement mortar, and the thermal insulation materials include but are not limited to thermal insulation materials such as polystyrene particles, expanded perlite, and foam glass. Through the above settings, the cement mortar, as the outer protection of the extruded board, can prevent direct damage to the extruded board by external environmental factors (such as ultraviolet rays, humidity, temperature changes, etc.), prevent water from penetrating into the extruded board layer, reduce the influence of moisture on the extruded board layer. At the same time, the cement mortar provides a flat surface for the extruded board layer, facilitating subsequent processing; further setting the thermal insulation cement mortar can, on the basis of the above advantages, increase the thermal insulation function of the cement mortar layer, which can be selected when the heat preservation requirement is high, and improve the overall thermal insulation performance of the composite extruded board.

[0026] Further, the shock-absorbing layer 4 is made of butyl rubber or nitrile rubber. The shock-absorbing layer 4 made of butyl rubber or nitrile rubber can absorb and disperse the impact force, reduce the direct impact on the extruded board, thereby protecting the extruded board layer. At the same time, the shock-absorbing layer 4 can provide a certain amount of expansion space to adapt to the thermal expansion and contraction of the extruded board and other materials due to temperature changes. Moreover, the shock-absorbing layer can serve as a stress release layer to reduce the cracking problems caused by uneven bonding or material shrinkage.

[0027] Further, the sound-insulating layer 6 is preferably made of rubber and plastic sound-insulating cotton, which has heat resistance and cold resistance, can remain stable within a relatively wide temperature range, and at the same time has the properties of sound insulation, heat insulation, moisture proof, fire prevention, shock proof, anti-corrosion, and insect prevention. At the same time, according to other different requirements, it can also be made of melamine cotton, pearl cotton or XPE material, etc.; the advantage of the sound-insulating layer 6 is that by adding the sound-insulating layer 6, the sound insulation performance of the building can be significantly improved, the interference of external noise on the indoor environment can be reduced, the noise pollution can be lowered, and the comfort of the living or working space can be improved; moreover, a good sound-insulating layer 6 can block the vibration caused by sound waves, etc., protect the inner layers such as the extruded board layer from vibration, and extend the service life of the board.

[0028] Further, the extruded board layer 1 includes but is not limited to being made of graphite extruded board or XPS extruded board. Among them, the graphite extruded board is made by adding graphite material to the extruded board and has relatively better heat insulation performance, while the XPS extruded board has relatively better water isolation performance, and can be selected adaptively. In addition, it should be noted that the interface of the extruded board can also be treated to enhance its bonding performance with the cement mortar.

[0029] Further, on the basis of the above, the extruded board layer 1 in the embodiment can be replaced by a polyurethane board. The polyurethane board is also a board with heat insulation performance. In certain cases, the two boards can be replaced to obtain different performance requirements.

[0030] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the design concept of the present utility model shall be included within the protection scope of the present utility model.
