Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Reference Figure 1 and Figure 3The utility model provides an embodiment: a heat-insulating and noise-reducing polyurethane board, comprising a polyurethane board body 1, a corrosion-resistant layer 8 is arranged inside the polyurethane board body 1, an aluminum foil layer 9 is arranged at the bottom of the corrosion-resistant layer 8, a bubble aluminum film layer 10 is arranged at the bottom of the aluminum foil layer 9, a polyurethane board core layer 11 is arranged at the bottom of the bubble aluminum film layer 10, a noise reduction board 12 is arranged at the bottom of the polyurethane board core layer 11, a sound-absorbing cotton board 13 is arranged at the bottom of the noise reduction board 12, a heat-insulating layer 14 is arranged at the bottom of the sound-absorbing cotton board 13, and the corrosion-resistant layer 8 is made of polyester. Resin, the thickness of the corrosion-resistant layer 8 is between 0.1 mm and 1 mm, the material of the bubble aluminum film layer 10 is a composite material composed of aluminum film and bubbles, the thickness of the bubble aluminum film layer 10 is between 0.1 mm and 0.5 mm, the material of the polyurethane board core layer 11 is polyurethane resin, the thickness of the polyurethane board core layer 11 is between 5 mm and 50 mm, the material of the noise reduction board 12 is high-density polyurethane material, the thickness of the noise reduction board 12 is between 5 mm and 20 mm, the material of the sound-absorbing cotton board 13 is polyester fiber, and the material of the thermal insulation layer 14 is polyurethane material.

[0024] The corrosion-resistant layer 8 is the outermost layer of the board. It is made of special corrosion-resistant materials and can effectively resist corrosion factors in the external environment, such as acid rain, salt spray, etc. This layer of protection not only extends the service life of the board, but also ensures the long-term beauty and stability of the building. The aluminum foil layer 9 is located under the corrosion-resistant layer 8. Its main function is to reflect heat. The aluminum foil has excellent reflective properties and can quickly reflect the heat irradiated on its surface back, thereby reducing the absorption and conduction of heat. This reflective effect plays an important role in thermal insulation, especially in summer. It can effectively reduce the internal temperature of the building, reduce the burden of air conditioning, and improve energy-saving performance. The bubble aluminum film layer 10 is another layer of thermal insulation material in the board. Its structure is similar to that of bubble packaging materials. It contains many tiny air bubbles inside. These bubbles can effectively block the conduction of heat and reduce heat loss. The bubble aluminum film layer 10 and the aluminum foil layer 9 work together to further enhance the thermal insulation effect of the board. The polyurethane board core layer 11 is the core part of the entire board. It provides thermal insulation and structural strength for the board. Polyurethane is a lightweight and high-strength material with good thermal insulation performance In the board, the polyurethane board core layer 11 plays a dual role of support and heat preservation, which not only ensures the stability of the board, but also improves the heat preservation effect. In addition to the above-mentioned heat preservation layer 14, the board is also provided with a noise reduction board 12 and a sound-absorbing cotton board 13. The noise reduction board 12 is mainly used to reduce the introduction of external noise and create a quieter environment for the room. It is made of special sound insulation materials and can effectively block the propagation of noise and improve the indoor comfort. The sound-absorbing cotton board 13 mainly absorbs and reduces the propagation of sound waves and improves the indoor acoustic environment of the building. The material can absorb the energy of sound waves, reduce the interference of echoes and noise, improve the indoor sound quality, and further enhance the comfort of the building. The thermal insulation layer 14 is an important component of the entire board. Its function is to reduce energy loss and improve the thermal insulation performance of the building. The thermal insulation layer 14 adopts high-efficiency thermal insulation materials, such as rock wool, glass wool, etc. These materials have excellent thermal insulation and heat insulation properties, can effectively block the loss of heat, and maintain the indoor temperature stable. By reasonably setting the thermal insulation layer 14, the energy consumption of the building can be reduced, and the overall energy efficiency level is improved.

[0026] When it is necessary to splice the polyurethane board body 1 and the polyurethane board body 2 3, it is only necessary to move the polyurethane board body 2 3 toward the direction of the polyurethane board body 1. During this process, the two insertion rods 4 will naturally be inserted into the inside of the socket 2. The clever design of the socket 2 is that it can squeeze the two movable rods 7. When the insertion rod 4 is inserted into the socket 2, the movable rod 7 is squeezed by the socket 2 and begins to move toward the inside of the groove 5. During this process, the movable rod 7 will squeeze the spring 6, causing the spring 6 to undergo elastic deformation. As an elastic element, the spring 6 has good restorability. Under the action of the spring 6, the movable rod 7 will be retracted into the inside of the groove 5 after the insertion rod 4 is inserted into the socket 2. At this time, the movable rod 7 is restored under the action of the spring 6, and the insertion rod 4 is tightly pressed, thereby completing the splicing of the polyurethane board body 1 and the polyurethane board body 2 3.

[0027] Working principle: when it is necessary to splice the polyurethane board body 1 and the polyurethane board body 2 3, move the polyurethane board body 2 3 toward the direction of the polyurethane board body 1, so that the two plug rods 4 are inserted into the inside of the socket 2, and the socket 2 squeezes the two movable rods 7, and the movable rod 7 is squeezed and moves toward the inside of the groove 5, squeezing the spring 6, and the spring 6 is squeezed and elastically deformed.

When the plug rod 4 is inserted into the inside of the socket 2, the movable rod 7 is restored under the action of the spring 6, and the plug rod 4 is pressed, thereby completing the splicing of the polyurethane board body 1 and the polyurethane board body 2 3, and realizing the convenience of installing the polyurethane board body 1 and the polyurethane board body 2 3, making the installation process simpler and more efficient, and can complete the project faster, shortening the construction period, and the corrosion-resistant layer 8 protects the entire plate from corrosion, extending the service life of the plate, and the aluminum foil layer 9 reflects heat The air bubble aluminum film layer 10 increases the thermal insulation effect, reduces heat conduction, and improves the thermal insulation performance.
