In the construction industry, their flame retardancy is used to prevent fires, which plays a decisive role in the safety of life and property. After the flame retardant materials are made, it is necessary to use testing equipment to detect their flame retardancy performance.

This type of flame retardancy performance detection equipment has the following defects:

[0004] After the material sample burns, only the flame retardancy is detected through the temperature detector and the flame detector, and the degree of attenuation of the mechanical properties reflected after the material burns cannot be detected, nor can the combustion products be collected or detected. In fact, the changes in the mechanical properties and the degree of pollution after the flame retardant material burns are also important indicators reflecting its quality. Therefore, the existing technology needs to be improved. Summary of the Invention

The other end of the collection plate communicates to the outside of the closed detection chamber and is jointly connected with the air pipe to a composite collection bottle.

[0007] As a further preference, the ignition mechanism includes a moving seat. One end of the moving seat extends outside the detection chamber and is connected to the driving pair in a transmission manner, while the other end extends into the detection chamber and is equipped with an igniter that can be moved below the through-opening. An introduction groove is formed on the collection plate, and a cover plate is provided on the top surface of the igniter. When the cover plate enters the introduction groove, it coincides with the top surface of the collection plate. The anti-plastic deformation detection assembly further includes a hanging wheel convex plate mechanism installed on the energy storage tube. The hanging wheel convex plate mechanism consists of a hanging plate with a roller guiding groove and a roller sliding in the roller guiding groove. The other end of the roller is connected to the moving seat through a connecting rod. A vertically downward guiding rod is installed at the top of the detection chamber. The top end of the hanging plate is provided with a bent portion, and the bent portion is slidably fitted on the guiding rod to achieve lifting and installation. One end of the hanging plate is connected to the energy storage tube. A return spring is sleeved on the guiding rod, and the bottom end of the guiding rod is provided with a limiting portion. The upper and lower ends of the return spring are elastically supported between the bent portion and the limiting portion.

[0008] As a further preference, the through-opening is vertical up and down. The self-adaptive pressure-applying rod is perpendicular above the through-opening and performs lifting relative to the through-opening.

[0009] As a further preference, the anti-plastic deformation detection assembly further includes an energy storage tube slidably fitted in the detection chamber through a track. The top end of the self-adaptive pressure-applying rod is slidably assembled in the energy storage tube, and a compression spring is provided between the top end of the self-adaptive pressure-applying rod and the top of the tube cavity of the energy storage tube. The bottom end extends outside the bottom end of the energy storage tube and is equipped with a stress pressure-applying member. A downwardly protruding stress portion is provided on the bottom surface of the stress pressure-applying member.

[0010] As a further preference, a hatch is hinged to one side of the detection chamber in the movement direction of the detection chamber relative to the moving seat.

[0011] As a further preference, a straight groove opening is formed on the side of the energy storage tube, and a bearing plate 9 corresponding to the bottom end of the straight groove opening is installed on the side of the energy storage tube. An extension plate 7 is installed at the top end of the self-adaptive pressure-applying rod.

The composite collection bottle has two compartments corresponding to the air pipe and the collection plate respectively. A gas detection device is provided in one compartment, and a weighing device is provided in the other compartment.

[0014] The beneficial effects of the present invention compared with the prior art are:

[0015] The present invention highlights the diversity of flame retardant material testing. As the degree of combustion of the bottom surface of the flame retardant material sample increases and strong plastic deformation is generated in the combustion area, the stress concentration of the corresponding adaptive pressure rod on the top surface of its opposite surface will become stronger, until the sample is broken from the burning place. The smoke generated during the combustion is collected by the mesh fireproof board and discharged into the composite collection bottle through the air pipe. Combustion products are generated during the combustion. The combustion products fall onto the collection plate as the sample is broken or fractured, and are discharged into the composite collection bottle through the collection plate. As the sample is broken, the detection time is completed, for example, it takes minutes, and the composite collection bottle is transferred to the gas detection equipment to detect the gas composition. The composite collection bottle is transferred to the weighing equipment to complete the weighing test of the combustion products. When the sample is subjected to the above-mentioned combustion test, three test items are obtained. One is that when the sample breaks after the combustion test, its flame retardant performance is obtained to resist deformation, its flame retardant performance is obtained to produce combustion products, and its flame retardant performance is obtained to produce polluted gas. According to the three test items obtained at the same time, the performance of this batch of flame retardant materials is comprehensively evaluated. The invention not only detects the flame retardancy, but also improves the detection effect. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation mode

[0023] The above and other implementation modes and advantages of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described implementation modes are only partial implementation modes of the present invention, rather than all implementation modes.

[0024] In one implementation mode, as Figures 1 - 6 shown:

[0025] This implementation mode provides a flame retardant performance inspection device for flame retardant materials, including a detection chamber 10, a detection table 20, an ignition mechanism 30, and an integrated detection mechanism 40. The detection table 20 is arranged in the detection chamber 10, and through holes 210 are provided on the upper and lower surfaces. The ignition mechanism 30 is located below the through holes 210. The integrated detection mechanism 40 includes an anti-plastic deformation detection component 410, an anti-odor detection component 420, and a pollutant detection component 430. The anti-plastic deformation detection component 410 includes an adaptive pressure rod 4110 arranged in the detection chamber 10 and capable of performing linear motion in the direction relative to the through holes 210. The anti-odor detection component 420 includes a mesh fireproof plate 4210 arranged on the opposite side of the adaptive pressure rod 4110 below the through holes 210. An air pipe 4220 communicating to the outside of the closed detection chamber 10 is provided on the mesh fireproof plate 4210. The pollutant detection component 430 includes a collection plate 4310 arranged on the opposite side of the adaptive pressure rod 4110 and connected to the mesh fireproof plate 4210. The other end of the collection plate 4310 communicates to the outside of the closed detection chamber 10 and is jointly connected with the air pipe 4220 to a composite collection bottle 4230.

[0026] In this embodiment, a flame-retardant material sample is selected and placed on the top surface of the detection table 20. The bottom end of the adaptive pressing rod 4110 abuts against the top surface of the sample and applies pressure to the top surface of the sample. The top end of the through-port 210 abuts against the bottom surface of the sample. The ignition mechanism 30 ignites the mesh-type refractory plate 4210. The flame is dispersed through the meshes on the mesh-type refractory plate 4210 and then burns upwards at the bottom surface of the sample through the through-port 210, and the timing starts. As the bottom surface of the sample burns, its top surface is pressurized by the bottom end of the adaptive pressing rod 4110. As the burning degree of the bottom surface of the sample increases, strong plastic deformation will occur in the burning area. Correspondingly, the stress concentration of the adaptive pressing rod 4110 on the opposite top surface will become stronger until the sample is broken at the burning part. Smoke will be generated during combustion. The smoke is collected by the mesh-type refractory plate 4210 and then discharged into the composite collection bottle 4230 through the air pipe 4220. Combustion will also cause plastic deformation in the burning area, from plastic deformation to the formation of plasticized combustibles. The combustibles fall off onto the collection plate 4310 along with the sample under the stress application of the burning area and the adaptive pressing rod 4110 on the top surface of the sample, and are discharged into the composite collection bottle 4230 through the collection plate 4310. As the sample is broken, the detection time is counted. For example, the time used is 5 minutes. The composite collection bottle 4230 is transferred to a gas detection device to detect the gas components, such as detecting the content of VOCs volatile organic compounds, H2S, NH3, and O2 in the combustion gas through a portable detector. The composite collection bottle 4230 is transferred to a weighing device to complete the weighing detection of the combustibles. When the sample undergoes the above combustion detection, three detection items are obtained. One is the ability of the sample to resist deformation during the combustion detection time until it breaks, the ability of the sample to produce combustibles in its flame-retardant performance, and the ability of the sample to produce polluting gases in its flame-retardant performance. According to the three detection items obtained simultaneously, the performance of this batch of flame-retardant materials is comprehensively evaluated. The present invention not only detects its flame retardancy but also improves the detection effect.

[0027] In another embodiment, the ignition mechanism 30 includes a moving seat 310. One end of the moving seat 310 extends outside the detection chamber 10 and is connected to a driving pair in a transmission manner, and the other end extends into the detection chamber 10 and is provided with an igniter 320 that can be moved below the through-port 210. An introduction groove 4320 is formed on the collection plate 4310. A cover plate 3210 is provided on the top surface of the igniter 320. When the cover plate 3210 enters the introduction groove 4320, it coincides with the top surface of the collection plate 4310.

[0028] In this embodiment, during the flame retardancy performance test, the moving seat 310 pushes the igniter 320 along the introduction groove 4320 into the collection plate 4310. At this time, the cover plate 3210 is inserted into the inlet groove 4320, and the top surface of the cover plate 3210 coincides with the top surface of the collection plate 4310 on the same plane. The sample to be tested is placed on the test bench 20. The igniter 320 sprays fire at the mesh-type refractory plate 4210, and the flame passes through the mesh and enters the through port 210, and is sprayed upward from the through port 210 onto the bottom surface of the sample. The bottom surface of the sample is burned, and the bottom end of the self-adaptive pressure rod 4110 presses the top surface of the sample, so that the stress is concentrated on the combustion area. As the combustion time prolongs, the stress concentration becomes stronger until the sample breaks in the combustion area. The flue gas generated during combustion is discharged into the composite collection bottle 4230 by the air pump and the air pipe 4220. The combustion products generated during fracture pass through the mesh and fall onto the collection plate 4310, and are discharged into the composite collection bottle 4230 through the collection plate 4310 to enhance the flue gas concentration. If the composite collection bottle 4230 is transferred, or a portable detector is installed on the composite collection bottle 4230 to detect the pollution of the gas, or the composite collection bottle 4230 is transferred and weighed to detect the amount of combustion products. The fire resistance of the flame retardant material is based on the time used for the sample to break. The pollution of the surrounding environment by the flame retardant material during flame retardancy is based on the time used for the sample to break and the nature of the collected flue gas. The amount of combustion products generated by the flame retardant material during flame retardancy is based on the time used for the sample to break and the amount of collected combustion products.

[0029] The anti-plastic deformation detection assembly 410 further includes a force storage tube 4111 slidably fitted in the detection chamber 10 through a track. The top end of the self-adaptive pressure rod 4110 is slidably assembled in the force storage tube 4111, and a compression spring 4112 is provided between the top end of the tube cavity of the force storage tube 4111. The bottom end extends outside the bottom end of the force storage tube 4111 and is provided with a stress application member 4113. The bottom surface of the stress application member 4113 is provided with a downward convex stress portion 4114. The anti-plastic deformation detection assembly 410 further includes a hanging wheel convex plate mechanism 4115 installed on the force storage tube 4111. One connection end of the hanging wheel convex plate mechanism 4115 is hinged to the moving seat 310, and the other connection end of the hanging wheel convex plate mechanism 4115 is hinged to the force storage tube 4111. While the moving seat 310 brings the igniter 320 to the bottom side position of the test bench 20, it drives the hanging wheel convex plate mechanism 4115 to drive the force storage tube 4111 to descend, and the bottom end of the stress application member 4113 is pressed against the top surface of the flame retardant material.

[0030] As Figure 4As shown in the figure, the hanging wheel convex plate mechanism 4115 is composed of a hanging plate 41152 provided with a roller guide groove 41151 and a roller 41153 sliding in the roller guide groove 41151. The other end of the roller 41153 is connected to the moving seat 310 through a connecting rod. A vertically downward guide rod 110 is installed at the top of the detection cabin 10. A bending part 41154 is provided at the top end of the hanging plate 41152. The bending part 41154 is slidably engaged on the guide rod 110 to achieve lifting and installation. One end of the hanging plate 41152 is connected to the force storage tube 4111. A return spring 1110 is sleeved on the guide rod 110. A limiting part 1111 is provided at the bottom end of the guide rod 110. The upper and lower ends of the return spring 1110 are elastically supported between the bending part 41154 and the limiting part 1111.

[0031] When the moving seat 310 moves the igniter 320 towards the bottom side position of the detection table 20, the roller 41153 will move linearly from the low point to the high point along the roller guide groove 41151. When the roller 41153 moves to the high point of the roller guide groove 41151, it forces the hanging plate 41152 to descend along the guide rod 110, and the return spring 1110 is compressed and shortened. The hanging plate 41152 drives the energy storage tube 4111 to descend, the energy storage tube 4111 drives the adaptive pressure rod 4110 to descend, and the adaptive pressure rod 4110 presses the stress pressing member 4113 at the bottom on the top surface of the sample. The ignition position of the igniter 320 and the sample are positioned. The igniter 320 sprays fire towards the mesh refractory plate 4210, and the flame passes through the mesh and enters the through port 210. When it is sprayed upward from the through port 210 to the bottom surface of the sample and starts to burn from the bottom surface, the bottom surface will undergo plastic deformation. Until after the bottom surface undergoes plastic deformation, the supporting force on the top surface cannot bear the driving force of the compression spring 4112 on the stress pressing member 4113, the compression spring 4112 releases its length downward, and the adaptive pressure rod 4110 pushes the stress pressing member 4113 to form a larger load on the top surface of the sample, forcing the sample to break effectively from the combustion area and completing the detection. The moving seat 310 moves the igniter 320 back in the reverse direction, and the roller retreats along the roller guide groove of the hanging plate 41152 to the low point. The spring releases its length, and through the bending portion 41154, it pushes the hanging plate 41152 to rise. The hanging plate 41152 drives the energy storage tube 4111 to rise. The pressure of the top of the inner cavity of the energy storage tube 4111 on the compression spring 4112 decreases, and the pressure of the bottom of the compression spring 4112 on the adaptive pressure rod 4110 decreases, reducing the pressure of the stress pressing member 4113 on the sample. Open the hatch and take out the sample. The setting of the hanging wheel convex plate mechanism 4115 enables the ignition of the igniter 320 and the pressing action of the adaptive pressure rod 4110 to be carried out synchronously. That is, when the operator places the sample on the detection table 20 and closes the hatch, only need to start the external kinematic pair, and the external kinematic pair drives the moving seat 310 to bring the igniter 320 below the detection table 20, then the stress pressing member 4113 can be synchronously positioned on the sample. After the sample is ignited, it constitutes the anti-deformation detection condition, improving the detection efficiency.

[0032] As Figure 2 shown, a hatch is hinged on one side of the detection chamber 10 relative to the moving direction of the moving seat 310. The hatch opens and closes relative to this side. Open the hatch or place the sample before detection on the detection table 20, or take out the sample after detection from the detection table 20. The hatch is in the moving direction of the moving seat 310. Therefore, when the adaptive pressure rod 4110 is triggered to reduce the pressure on the sample after the moving seat 310 moves backward, it is convenient to take out the sample from its opposite side. A transparent window is provided in front of the detection chamber 10, facilitating real-time observation of the detection process.

[0033] In another embodiment, as Figure 2 、Figure 3 and Figure 5 As shown in Figure 5 , a straight notch 4116 is formed in the side of the energy storage tube 4111. A bearing plate 4119 corresponding to the bottom end of the straight notch 4116 is installed on the side of the energy storage tube 4111. An extension plate 4117 is installed at the top of the adaptive pressure rod 4110. The extension plate 4117 extends out of the energy storage tube 4111 through the straight notch 4116, and a pressure sensor 4118 is installed between the extension plate 4117 and the bearing plate 4119. A display screen is provided in front of the detection chamber 10.

[0034] When the sample starts to burn from the bottom surface, the burning area is the concentrated area of stress deformation. The top of the adaptive pressure rod 4110 is elastically supported downward by the compression spring 4112, so that the adaptive pressure rod 4110 has a downward extrusion force. This extrusion force is transmitted to the top surface of the sample by the stress pressing member 4113, and the extrusion point is directly opposite to the burning point up and down, so that the sample is most likely to generate stress and bend deformation in this burning area. As the burning degree of the sample changes, the bending degree gradually increases, the downward release length of the compression spring 4112 gradually increases, the downward pressing amplitude of the adaptive pressure rod 4110 will increase, the downward amplitude of the extension plate 4117 driven by the adaptive pressure rod 4110 will increase, the downward amplitude of the extension plate 4117 driving the pressure sensor 4118 will increase, and the feedback signal of the detection end of the pressure sensor 4118 on the bearing plate 4119 will be greater. After being converted by the controller module and displayed on the display screen, the pressure value range is detected. According to the pressure value, the change of the pressure value of the sample from ignition to fracture is known. For example, the displayed range of the pressure value after the sample burns and fractures in 3 minutes is the plastic anti-deformation ability of the sample during flame retardancy, realizing intelligent detection.

[0035] The mesh refractory plate 4210 is a downwardly convex conical mesh cover, which provides a flame combustion space when igniting the igniter 320. The air pipe 4220 is connected to a conical surface of the mesh refractory plate 4210 through a filter tip. The outer end of the air pipe 4220 is connected to an air pump. The flue gas generated after the sample burns is concentrated downward into the conical mesh cover of the mesh refractory plate 4210 and discharged into the composite collection bottle 4230 through the air pipe 4220 for collection. The collection plate 4310 is inclined downward and connected to the composite collection bottle 4230 outside the closed detection chamber 10. The connecting end of the mesh refractory plate 4210 and the collection plate 4310 is inclined towards the direction of the collection plate 4310. The composite collection bottle 4230 has two compartments corresponding to the air pipe 4220 and the collection plate 4310 respectively. During actual assembly and use, in order to achieve real-time detection, a gas detection device is provided on the compartment of the composite collection bottle 4230 corresponding to the air pipe 4220, and the detected gas detection signal is fed back to the display screen. A weighing device is provided in the compartment of the composite collection bottle 4230 corresponding to the collection plate 4310 to perform actual weighing detection on the collected combustion products. Both gas detection and weighing detection serve the samples selected for the flame retardant material, and the detection time also ends when the sample burns and breaks. The plastic deformation ability, the output ability of polluting gases and combustion products of this type of flame retardant material during flame retardancy are obtained through the time used and the detected data, and the practical performance of this type of flame retardant material is obtained.

[0036] It should be further noted that the kinematic pair mentioned in the present invention is a relatively broad power device, as long as it can drive the moving seat 310 to perform reciprocating linear motion, such as a motion rod or a motion platform driven by a motor or an electro-hydraulic cylinder. The detection device or the portable detector mentioned in the present invention is a detector device for detecting polluted air, which are all prior arts and will not be elaborated here.
