[0002] Polystyrene composite insulation board is a kind of insulation material widely used in the construction field. It integrates the three functions of structure, maintenance and insulation, and provides an efficient insulation solution for the building exterior wall. The board is usually made of calcium silicate board as the surface layer, polystyrene particles and cement foam as the reinforcement layer, and polystyrene insulation board as the middle layer through a series of complex processes. This board not only has good insulation performance, but also can effectively prevent quality problems such as cracking and falling off of wall insulation projects, while avoiding fire safety hazards, and achieving the purpose of the same life of building insulation and wall.

[0003] Although the existing polystyrene composite insulation board is relatively mature in technology and application, there are still some challenges and limitations. Among them, one of the most significant problems is its fire resistance. Since the main components of polystyrene composite insulation board include organic materials, these materials are easily damaged under long-term high-temperature burning, which in turn affects its thermal insulation performance and structural stability. Utility Model Content

[0004] In order to overcome the disadvantage that the polystyrene composite thermal insulation board is easily damaged after a long period of burning, thereby reducing the thermal insulation performance, the utility model aims to provide a polystyrene composite thermal insulation board with a flame retardant function.

[0005] The technical solution is: a polystyrene composite insulation board with flame retardant function, including a polystyrene composite board, and also including a mounting plate, a servo motor, a screw rod, a connecting plate, an extrusion plate, a piston, a water pipe and a rubber sheet.

[0007] As an improvement of the above solution, it also includes a fixing bracket, a fixing screw and a blade. The fixing bracket is fixed to the inner side of the extrusion plate by the fixing screw. The fixing bracket is fixed with a blade, and the blade can contact the rubber sheet.

[0008] As an improvement of the above solution, a ring is further included, which is arranged outside the water pipe.

[0009] As an improvement of the above solution, a rubber pad is also included, and the rubber pad is arranged in the piston.

[0011] As an improvement of the above solution, a warning light is also included, and the warning light is connected to the outside of the extrusion plate.

[0012] Through the above-mentioned optimization scheme, the beneficial effect achieved by the utility model is: the extrusion plate is driven by the servo motor to move horizontally, the extrusion plate pushes the piston to pressurize the water pipe, the flame retardant in the water pipe will be sprayed out through the expanded and ruptured rubber sheet, and the flame retardant is guided to the inner wall of the inner cavity of the polystyrene composite board, thereby achieving an active flame retardant effect, thereby improving the fireproof quality of the polystyrene composite board.

[0018] The above scheme is further described below in conjunction with specific examples. It should be understood that these examples are used to illustrate the present application and are not limited to the scope of the present application. The implementation conditions adopted in the examples can be further adjusted according to the conditions of the specific manufacturer, and the implementation conditions not specified are usually the conditions in conventional experiments.

[0019] Embodiment: A polystyrene composite insulation board with flame retardant function, such as Figure 1-Figure 4As shown, it includes a polystyrene composite board 1, and also includes a mounting plate 2, a servo motor 3, a screw 4, a connecting plate 5, an extrusion plate 6, a piston 601, a water pipe 7 and a rubber sheet 8. The middle part of the polystyrene composite board 1 is hollow, the mounting plate 2 is fixedly connected in the polystyrene composite board 1, the servo motor 3 is fixed to the mounting plate 2, the output shaft of the servo motor 3 is connected with the screw 4, the connecting plate 5 is slidably connected in the polystyrene composite board 1, the connecting plate 5 is connected to the screw 4 by a thread, the connecting plate 5 is fixedly connected with the extrusion plate 6, and a horn 15 and a warning light 16 are arranged on the outside of the extrusion plate 6. Four water pipes 7 are connected in the polystyrene composite board 1 (taking the conventional specifications of the polystyrene composite board 1 as an example, four water pipes are arranged in the polystyrene composite board 1 of 1m*1m*15cm to achieve the effect of uniformly spraying the flame retardant), the bottom of the water pipe 7 is bent and the end is connected with a telescopic piston 601, the extrusion plate 6 is connected to the piston 601, a through groove is opened on the side of the water pipe 7, and the rubber sheet 8 is sealed at the corresponding position of the through groove.

[0020] like Figure 1-Figure 3 As shown, a temperature detector 9 is also included. The temperature detector 9 is fixed outside the polystyrene composite board 1 , and the temperature detector 9 is electrically connected to the servo motor 3 .

[0021] like Figure 2 and Figure 4 As shown, it also includes a fixing bracket 10 , a fixing screw 11 and a blade 12 . The fixing bracket 10 is fixed to the inner side of the extrusion plate 6 by the fixing screw 11 . The blade 12 is fixedly connected to the fixing bracket 10 , and the blade 12 can contact the rubber sheet 8 .

[0022] like Figure 2 As shown, a ring 13 is also included, and the ring 13 is arranged outside the water pipe 7.

[0023] like Figure 2 As shown, a rubber pad 14 is also included. The rubber pad 14 is arranged in the piston 601 to improve the sealing performance of the piston 601.

[0024] Working principle: When the polystyrene composite board 1 encounters open flame, it uses its own fire resistance to prevent fire. At the same time, the temperature detector 9 monitors the internal temperature of the polystyrene composite board 1. When the temperature reaches the preset critical warning temperature, the temperature detector 9 drives the servo motor 3 to turn on, and the servo motor 3 drives the screw 4 to rotate. The screw 4 pushes the connecting plate 5 to move toward the inside of the polystyrene composite board 1, thereby driving the extrusion plate 6 to move synchronously. The extrusion plate 6 pushes the piston 601 to pressurize the water pipe 7. The water pipe 7 is filled with flame retardant. After pressurization, the water pipe 7 will extract the flame retardant by stretching and breaking the rubber sheet 8. In order to increase the amount of flame retardant extracted, the blade 12 on the fixed bracket 10 fixedly connected to the extrusion plate 6 can cut the rubber sheet 8, so that the flame retardant in the water pipe 7 can be sprayed out smoothly, and the flame retardant is sprayed to the inner wall of the inner cavity of the polystyrene composite board 1 to achieve the effect of active flame retardancy, thereby improving the fireproof quality of the polystyrene composite board 1.
