Technical Field

[0001] The utility model relates to the technical field of fire retardant coatings, in particular to a coating fire retardant performance detection device. Background Art

[0002] Fire retardant coating is a coating that is applied to the surface of a material to improve the material's fire resistance, slow down the spread of flames, or prevent combustion for a certain period of time. This type of coating is called fire retardant coating, or flame retardant coating.

[0003] The existing fire retardant coating detection equipment mainly focuses on the combustion and temperature changes of the coating during the detection process, but the detection of the gas components and concentrations generated during the combustion process is relatively limited. Fire retardant coatings may produce harmful gases during combustion. The types and concentrations of these gases are crucial for evaluating the fire retardant performance of the coating and its impact on the environment. In addition, during the detection process, the coating samples may shift or fall off. Therefore, the utility model proposes a coating fire retardant performance detection device.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] The following is an explanation of the preferred embodiments of the device of the utility model.

[0025] See also Figure 1-5As shown, the coating fire retardant performance testing equipment comprises a testing box 1, a display screen 101 is arranged in front of the testing box 1, a side steel plate 2 is arranged on one side of the testing box 1, the side steel plate 2 is composed of an upper side plate 201 and a lower side plate 202, and the upper side plate 201 and the lower side plate 202 are independent of each other, a top cover 6 is arranged on the top of the testing box 1, and legs 7 are arranged at the four corners of the bottom of the testing box 1, and a mounting frame 8 is arranged on the top of the internal top of the testing box 1, and the mounting frame 8 is used to fix the gas sensor 801 to ensure that it is in the testing state. In order to ensure the stability and accuracy during the test, a gas sensor 801 is fixedly installed on the mounting frame 8. The gas sensor 801 can monitor the changes in gas concentration generated during the combustion of the paint in real time. The interior of the detection box 1 is provided with a transmission pipeline 9 below the gas sensor 801. The transmission pipeline 9 is used to transmit the fuel gas to the flame head 12. A mounting seat 10 is provided at the bottom of the transmission pipeline 9. The bottom of the mounting seat 10 is connected to an air intake pipe 11, and a flame head 12 is provided at the bottom of the air intake pipe 11. A solenoid valve 13 is installed around the outer body, and the design of the transmission pipeline 9 and the mounting seat 10 allows the gas to be smoothly transmitted to the flame head 12. The bottom of each mounting seat 10 is provided with an air inlet pipe 11, a flame head 12 and a solenoid valve 13. Through cooperation, the equipment can perform combustion tests on multiple paint samples at the same time, thereby improving the test efficiency. By accurately controlling the switch of the solenoid valve 13, the flame size and burning time can be accurately adjusted, thereby simulating the combustion of the paint under different fire conditions. A pull plate 4 is inserted into the opening on the lower side plate 202, and a positioning component 14 is provided on the pull plate 4. Specifically, the design of the positioning plate 1401 allows paint samples of different thicknesses to be placed on the plate, and then the size of the gas flow of the flame head 12 is adjusted by the solenoid valve 13. The combustion of the paint under different fire source intensities can be simulated through multiple groups of detections, and then the gas sensor 801 will monitor the changes in gas concentration generated by the combustion of the paint in real time. By collecting and analyzing these gas concentration data, the fire retardant performance of the paint under different conditions can be evaluated. At the same time, by comparing the gas concentration data under different coating thicknesses and different fire conditions, we can further analyze the influence of coating thickness and fire intensity on the fire retardant performance of the coating.

[0026] Furthermore, the mounting seat 10 is provided with three groups, and the bottom of each mounting seat 10 is provided with an air intake pipe 11, a flame head 12 and a solenoid valve 13 in sequence, and the positioning assembly 14 includes a positioning plate 1401, a limiting steel spring 1402, an annular plate 1403 and a limiting piece 1404, and the four sides of the positioning plate 1401 are provided with limiting steel springs 1402, and the top of the limiting steel spring 1402 is fixedly connected with a circular ring plate 1403, and the top of the circular ring plate 1403 is provided with a limiting piece 1404. Specifically, the positioning plate 14 01 As the basic platform for placing the paint sample, the limiting steel spring 1402 cooperates with the limiting plate 1404. Since the limiting steel spring 1402 has a certain elasticity and tension, the thicker the paint sample is, the more firmly it is fixed. The paint sample can be firmly fixed on the positioning plate 1401 to prevent it from moving during the test. This not only improves the reliability and accuracy of the test, but also helps to reduce the test error caused by sample movement or falling off, making the test results more reliable and instructive.

[0027] Furthermore, a handle 3 is provided on the outside of the pull plate 4, and a slide groove 401 is provided on both sides of the pull plate 4. A protective cover 5 is provided on the same side of the pull plate 4 and above the pull plate 4. The protective cover 5 is connected to the transmission pipe 9. Three groups of positioning components 14 are provided on the pull plate 4. The three groups of positioning components 14 correspond to the three groups of flame heads 12. Limiting strips 15 are provided on both sides of the bottom of the inner cavity of the detection box 1 corresponding to the slide groove 401. The limiting strips 15 and the slide groove 401 are slidably matched. The pull plate 4 can slide in the detection box 1 through the cooperation of the slide groove 401 and the limiting strip 15, which is convenient for placing and removing the paint sample. By cooperating with the positioning component 14, the paint sample can be quickly placed and removed, thereby improving the test efficiency. At the same time, the combination of the slide groove 401 and the limiting strip 15 ensures the stability and accuracy of the sliding of the pull plate 4.

[0028] When in use, first pull out the pull plate 4 and place the paint samples of different thicknesses on the positioning plate 1401. Use the limit steel spring 1402, the annular plate 1403 and the limit plate 1404 in the positioning assembly 14 to ensure that the paint sample can maintain a stable position during the test, then push the pull plate 4 back into the detection box 1, open the protective cover 5 to connect the transmission pipeline 9 with the gas pipe, and then adjust the solenoid valve 13 to detect the changes in gas concentration of paint samples of different thicknesses under the spray heads 12 of different flame sizes, and then adjust the solenoid valve 13 to detect the gas concentration of paint samples of different thicknesses under the spray heads 12 of the same flame size, then take out the paint sample, and then place the paint sample of the same thickness on the positioning plate 1401, and then repeat multiple tests under different conditions. During the test, the gas sensor 801 will monitor the changes in gas concentration generated by the combustion of the paint in real time. By collecting and analyzing these gas concentration data, the fire retardant performance of the paint under different conditions can be evaluated. At the same time, by comparing the gas concentration data under different coating thicknesses and different fire conditions, the influence of coating thickness and fire intensity on the fire retardant performance of the coating can be further analyzed. Through the setting of three groups of flame heads 12 and solenoid valves 13, the detection coordination between the gas sensor 801 has significantly improved the efficiency and accuracy of the coating fire retardant performance detection equipment, and also provided strong support for the evaluation of the coating fire retardant performance.
