[0002] Silicone sealant is a paste formed by using polydimethylsiloxane as the main raw material, adding silane coupling agents, fillers, catalysts, crosslinking agents and other auxiliary materials and then mixing under vacuum conditions. When silicone sealant contacts air, it will undergo a crosslinking reaction and cure to form elastic silicone rubber. After curing, it has a series of advantages such as resistance to high and low temperatures, anti-aging, anti-ultraviolet rays, ozone resistance, resistance to dilute acids and erosion by certain solutions. Therefore, silicone sealant is widely used in various fields such as automobiles, buildings, new energy, electronics, aerospace, etc. Flame-retardant silicone sealant is a special-purpose silicone sealant with high temperature resistance and flame retardant effects.

[0018] The effect achieved by the above components is that when the clamping plate and the fixed block clamp the silicone sealant, the spring is in a contracted state. Therefore, the elastic force of the spring acts on the clamping plate, making the limit more stable.

[0028] Reference Figures 1 to 3 , a protective structure 5 is provided on the operating table 1, and the protective structure 5 is mainly composed of a protective box 51, the protective box 51 is fixedly connected to the operating table 1 or that one, and the protective box 51 is rotatably connected to the cover body 52, and the cover body 52 is connected to the air guide pipe 53, and one end of the air guide pipe 53 is connected to the spray chamber 54, and the silicone sealant is placed in the protective box 51, the cover body 52 is closed, and the gas tank 2 is opened, so that the gas in the gas tank 2 passes through the conduit 3 to make the flame head 4 spray fire, and the silicone sealant is flame-retardant tested. A piece of transparent material is provided on the cover body 52 to facilitate the staff to observe the state of the silicone sealant and then conduct flame-retardant performance testing on it. Under the joint action of the protective box 51 and the cover body 52, the harmful gas generated by the combustion will not be released into the air, and will enter the spray chamber 54 through the air guide pipe 53, thereby avoiding the harmful gas generated by the silicone sealant during the combustion test, which is directly released into the air, causing damage to the laboratory environment and the work In order to prevent the occurrence of physical injuries to workers, a spray pipe 55 is fixedly connected to the spray chamber 54, and a number of spray heads 56 are fixedly connected to the spray pipe 55. The spray pipe 55 is connected to the outdoor liquid pump, and the chemical solution or water is pumped to the spray pipe 55 by the liquid pump and sprayed to the exhaust gas through the number of spray heads 56, so that the particulate matter and some harmful gases in the gas are dissolved or reacted to remove them. The spray chamber 54 is connected to an adsorption chamber 57, and an activated carbon filter plate 58 is fixedly connected to the adsorption chamber 57. The adsorption chamber 57 is connected to an exhaust pipe 59. The gas after preliminary purification enters the adsorption chamber 57 and will be adsorbed by the activated carbon filter plate 58, which can effectively adsorb VOCs, some acidic gases and odors. The gas after further purification becomes harmless gas and is discharged through the exhaust pipe 59. A limiting column 510 is slidably inserted on the cover body 52, and a limiting groove 511 is provided on the protective box 51. The limiting column 510 is stuck into the limiting groove 511 to limit the cover body 52.
[0029] Reference Figure 3 and Figure 4 On the protective box 51, a clamping structure 6 is provided. The clamping structure 6 is mainly composed of two fixing blocks 61. The two fixing blocks 61 are respectively fixedly connected to the inner walls on both sides of the protective box 51. The two ends of the silicone sealant are respectively placed on the two fixing blocks 61. Slide grooves 62 are respectively opened on the inner walls on both sides of the protective box 51.

A spring 64 is fixedly connected to the inner wall of the slide groove 62. One end of the spring 64 is fixedly connected to the clamping plate 63. When the clamping plate 63 and the fixing block 61 clamp the silicone sealant, the spring 64 is in a contracted state. Therefore, the resilient force of the spring 64 acts on the clamping plate 63, making the limit more stable. A round rod 65 is fixedly connected to the clamping plate 63. The round rod 65 is slidably inserted on the protective box 51. Two round grooves 66 are opened on the cover body 52. When the cover body 52 is covered, the round grooves 66 will squeeze the round rod 65, which can further push the clamping plate 63 and further improve the stability of the limit.

A transparent material is used on the cover body 52, which is convenient for the staff to observe the state of the silicone sealant, and then conduct a flame retardancy performance test. Under the combined action of the protective box 51 and the cover body 52, the harmful gases generated by combustion will not be released into the air, but will enter the spray chamber 54 through the air duct 53, thus avoiding the situation that the harmful gases generated during the combustion test of the silicone sealant are directly released into the air, which will cause damage to the laboratory environment and the health of the staff. Connect the spray pipe 55 to the liquid pump outdoors. The chemical solution or water is pumped to the spray pipe 55 by the liquid pump and sprayed onto the waste gas through a number of spray heads 56. The particulate matter and some harmful gases in the gas are dissolved or reacted to be removed. The gas after preliminary purification enters the adsorption chamber 57, and will be adsorbed by the activated carbon filter plate 58, which can effectively adsorb VOCs, some acidic gases and odors. The gas after secondary purification becomes harmless gas and is discharged through the exhaust pipe 59. Snap the limit post 510 into the limit groove 511 to limit the cover body 52. Place the two ends of the silicone sealant on the two fixing blocks 61 respectively, and then slide the two clamping plates 63 so that the fixing blocks 61 and the clamping plates 63 jointly clamp the silicone sealant. When the clamping plate 63 and the fixing block 61 clamp the silicone sealant, the spring 64 is in a contracted state, so the resilient force of the spring 64 acts on the clamping plate 63, making the limit more stable. When the cover body 52 is covered, the round grooves 66 will squeeze the round rod 65, which can further push the clamping plate 63 and further improve the stability of the limit.
