Description

Technical Field

[0001] The present invention relates to the field of silicone-based adhesive testing, and in particular to a silicone-based adhesive sealing performance testing device and a method for using the same. Background Art

[0002] Fireproof silicone putty is a fireproof material with silicone-based glue as the main component and supplemented with flame retardants and other ingredients. It is flexible and plastic at room temperature and is suitable for sealing and fireproofing various holes. The existing testing of the sealing and fireproofing performance of silicone putty only uses flames to continuously burn the surface of the silicone putty to test its fireproof and burning resistance. However, it is unable to simulate the continuous burning of flames when the silicone putty is actually sealing holes, and how long it will take for the silicone putty to be burned through, thus losing its sealing and fireproofing effect.

[0003] At the same time, the filling amount of silicone mud and the thickness of silicone mud are different for holes of different depths, which will affect the fire resistance and time of silicone mud. Currently, it is impossible to perform sealing and fire protection testing of silicone mud in this situation. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing method of only burning the surface of silicone mud by flame, which cannot simulate the actual situation of silicone mud sealing holes and the obtained results are not in line with reality, the present invention provides a silicone-based adhesive sealing performance testing device and a method for using it.

[0006] In addition, it is particularly preferred that the bending assembly includes a ball pin 1, an electric push rod, a ball pin 2, a mounting ring, a connecting block, a limit ring, a slider, a slide rod, a supporting block and a locking rod; each mounting frame is connected to a ball pin 1; each ball pin 1 is fixedly connected to an electric push rod; a ball pin 2 is fixedly connected to the output end of the electric push rod; the two ball pins 2 are commonly connected to the mounting ring; two connecting blocks are fixedly connected to the mounting ring, and the connecting blocks are directly opposite to the gap between the two adjacent guide rods; the two connecting blocks are commonly fixedly connected to the limit ring; each connecting block is slidably connected to a slider; each slider is slidably connected to an L-shaped slide rod; the horizontal end of the L-shaped slide rod faces the limit ring; the horizontal end of the L-shaped slide rod is fixedly connected to the supporting block; each slider is screwed with a locking rod for locking the slide rod.

[0007] In addition, it is particularly preferred that the inner walls of the placement tube and the extension tube are roughened.

[0008] In addition, it is particularly preferred that an adaption groove is further included; each partition plate is provided with an adaption groove for evading cables on one side facing the center of the extension tube; the adaption groove is semicircular.

[0009] In addition, it is particularly preferred that one end of the guide rod away from the extension tube is screwed to a limit bolt.

[0010] Furthermore, it is particularly preferred that the straight edges of the partition plate are beveled.

[0011] In addition, it is particularly preferred that a groove adapted to fit the connecting rod is provided on the upper surface of the supporting block.

[0012] In addition, it is particularly preferred that an arc-shaped piece is fixedly connected to one end of the screw rod facing the center of the placement barrel; and a hand wheel is fixedly connected to one end of the screw rod away from the placement barrel.

[0013] In addition, it is particularly preferred that an adaptation component is also included, the adaptation component includes an insert plate and a rotating ring; the adaptation groove is set to a rectangle; a storage cavity is opened in each partition plate; each partition plate is slidably connected to a plug plate on the side facing the center of the extension tube; the plug plate is blocked and can be stored in the corresponding storage cavity; a number of springs are connected between the storage cavity and the corresponding plug plate; a rotating ring is rotatably connected to each extension tube; all guide rods on the same extension tube are fixedly connected to the corresponding rotating ring.

[0014] A method for using a silicone-based adhesive sealing performance testing device comprises the following steps: Step 1: Place the tube and extension tube on the base to form a simulated hole; Step 2: Fill the simulated hole with silica gel for testing. The depth of the simulated hole can be changed by adding or removing extension tubes to obtain simulated holes of different depths for testing. Step 3: Start the flame stove and continue burning the silica gel mud in the simulated hole for 30 minutes. Then observe and test the burned silica gel mud to determine the fire resistance of the silica gel mud.

[0015] The beneficial effects of the present invention are as follows: the present invention realizes a simulated hole scene by placing a tube and an extension tube arranged from top to bottom, filling the hole with silicone mud, and continuously burning the flame from the bottom, so as to judge whether the silicone mud filled in the hole of the current depth will be burned through by the flame within the detection time and lose the sealing effect; at the same time, by removing the extension tube to change the depth of the simulated hole, the fire-proof performance of the silicone mud filled in holes of different depths is tested to obtain the optimal thickness of the silicone mud that needs to be filled in actual use, and provide data support for the subsequent actual use of the silicone mud, so as to calculate the optimal thickness of the silicone mud filled in different usage scenarios.

[0016] By inserting cables into the placement tube and the extension tube, and then filling them with silicone mud, we simulate the actual holes with cables inserted. The test results are compared with those without cables inserted to check whether the fire protection of the silicone mud is different after the cables are inserted. Then, we can find out whether the insertion of cables in the silicone mud has an impact on the fire protection of the silicone mud. In addition, we can check whether the part of the cable located in the silicone mud is ignited to judge the fire blocking effect of the silicone mud. When the cable is in the silicone mud, the depth of the simulated hole is changed by adding or removing extension tubes, and the fire protection of the silicone mud is further obtained when the cables are inserted through holes of different depths. By bending the cable and squeezing the silicone mud, we simulate the actual cable being bent by external force and squeezing the silicone mud to cause its deformation to determine whether it will affect the sealing and fireproof performance of the silicone mud.

[0021] The bending assembly includes a ball pin 201, an electric push rod 202, a ball pin 203, a mounting ring 204, a connecting block 205, a limiting ring 206, a slider 207, a slide bar 208, a supporting block 209 and a locking rod 210; each mounting frame 11 is connected to a ball pin 201; each ball pin 201 is fixed to an electric push rod 202; the output end of the electric push rod 202 is fixed to a ball pin 203; the two ball pins 203 are connected to the mounting ring 204; the mounting ring 204 is fixed to a Two symmetrically distributed connecting blocks 205 are directly opposite to the gap between the two adjacent guide rods 4; the two connecting blocks 205 are commonly fixed to the limit ring 206; each connecting block 205 is slidably connected to a slider 207; each slider 207 is slidably connected to an L-shaped slide rod 208; the horizontal end of the L-shaped slide rod 208 faces the limit ring 206; the horizontal end of the L-shaped slide rod 208 is fixed to a supporting block 209; each slider 207 is screwed with a locking rod 210.

[0022] The inner walls of the placement tube 2 and the extension tube 3 are roughened to increase friction and prevent the silicone mud filled therein from sliding downward.

[0023] It also includes an adapting groove 61; each partition plate 6 is provided with an adapting groove 61 for avoiding cables on one side facing the center of the extension tube 3; the adapting groove 61 is semicircular.

[0024] The end of the guide rod 4 away from the extension tube 3 is screwed with a limit bolt 41; the limit bolt 41 is used to limit the movement position of the connecting rod 5, and also facilitates the removal of the connecting rod 5 and the partition plate 6 from the guide rod 4 for cleaning.

[0025] The straight edge of the partition plate 6 is provided with an oblique angle, so that the partition plate 6 can be inserted into the silica gel mud to separate it.

[0026] A groove adapted to the connecting rod 5 is formed on the upper surface of the supporting block 209 , thereby increasing the stability of the supporting block 209 when supporting the connecting rod 5 .

[0027] An arc-shaped piece 101 is fixed to one end of the screw rod 10 facing the center of the placement tube 2, which is used to increase the stability when clamping the cable; a hand wheel 102 is bolted to one end of the screw rod 10 away from the placement tube 2, which facilitates the user to rotate the screw rod 10.

[0028] When the present invention is used to test the hole sealing fireproof performance of silica gel mud, Figure 4 As shown, the user arranges the placement tube 2 and the extension tube 3 from top to bottom and installs them on the mounting rod 12, with the placement tube 2 at the bottom, thereby simulating a hole scene. Then, the user inserts the silicone mud into the placement tube 2 and the extension tube 3 from the top extension tube 3, and fills the inside of the placement tube 2 and the extension tube 3. Then, gas is supplied to the gas pipeline connected to the flame stove 7, and the flame stove 7 is started to generate a flame. The flame starts to burn from the bottom of the placement tube 2. At this time, the user can place a napkin on the surface of the silicone mud on the top extension tube 3, wait for the flame to burn from the bottom for thirty minutes, and observe whether the napkin is ignited, thereby judging whether the silicone mud filled in the hole of the current depth will be burned through by the flame within the detection time and lose the sealing effect. At the same time, while the flame continues to burn, the user can use a thermometer to detect the temperature of the silicone mud surface of the top extension tube 3 to obtain the thermal conductivity index of the silicone mud. After multiple measurements and records, the fire resistance of the silicone mud can be further obtained.

[0029] If the flame cannot burn through the silicone mud in the current depth simulated hole within the detection time, the depth of the simulated hole can be reduced at this time, thereby reducing the thickness of the silicone mud. The implementation method is to gradually remove each extension tube 3 from the mounting rod 12. The specific operation steps take the removal of the top extension tube 3 as an example: before removing the extension tube 3, first turn off the flame of the flamethrower 7, and then the user holds the two connecting rods 5 corresponding to the top extension tube 3 and lifts the extension tube 3 upward so that the bottom surface of the partition plate 6 connected to the top extension tube 3 is flush with the top surface of the middle extension tube 3, and then pushes the connecting rod 5 to slide toward the extension tube 3 along the guide rod 4. The connecting rod 5 pushes the partition plate 6 to slide toward the extension tube 3, and then the partition plate 6 is inserted between the top and middle extension tubes 3, and the partition plate 6 is inserted into the silicone mud of the simulated hole. After the two partition plates 6 come into contact, the silicone mud in the top extension tube 3 and The silicone mud at the bottom is separated, and then the user continues to lift up the top extension tube 3, and the partition plate 6 will drive the silicone mud in the extension tube 3 to move upward together, and then the silicone mud in the middle extension tube 3 will be exposed. The user can observe whether the surface of the silicone mud in the middle extension tube 3 is burned through or there are signs of burning. If not, continue to remove the middle extension tube 3 in the same way, and check the surface condition of the silicone mud in the placement tube 2, and then know within the detection time (thirty minutes), among the holes of different depths composed of the placement tube 2 and the two extension tubes 3, which depth of the holes will reach the fire resistance limit of the silicone mud; thus, the present invention can simulate holes of different depths, and then within the detection time (thirty minutes), test the fire retardant performance of silicone mud filled in holes of different depths, so as to obtain the optimal thickness that the silicone mud needs to be filled in actual use.

[0030] Furthermore, within the detection time (thirty minutes), if the surface of the middle extension tube 3 is burned through or there are signs of burning, it means that within the detection time, the silicone mud filled in the hole of this depth (the hole formed by the placement tube 2 and the middle extension tube 3) cannot ensure the sealing and fireproof performance, then the silicone mud inside the middle extension tube 3 and the placement tube 2 is cleaned, and new silicone mud is replaced in the middle extension tube 3 and the placement tube 2, and the placement tube 2 and the two extension tubes 3 are reinstalled on the installation rod 12 in order (if there are no signs of burning on the bottom surface of the silicone mud in the previously removed top extension tube 3, then No need to replace, if there are signs of burning, new silicone mud needs to be replaced to ensure the rigor of the test), and then the silicone mud in the placement tube 2 and the two extension tubes 3 are not burned at this time, and then the flame stove 7 is reopened. Based on the time used for the previous test (30 minutes), the test time is extended until the top of the silicone mud in the top extension tube 3 is burned through, and then the maximum fire resistance time of silicone filled in the deepest hole formed by the placement tube 2 and the two extension tubes 3 is obtained, which provides data support for the subsequent actual use of silicone mud, so as to calculate the optimal thickness of silicone mud filling in different usage scenarios.

[0031] During the detection process, the protective net 8 is located between the placement tube 2 and the flame stove 7 to prevent the silicone mud in the placement tube 2 from falling onto the flame stove 7 when filling and burning the silicone mud, blocking the flame port of the flame stove 7 and affecting the detection operation. In addition, the protective net 8 is a high-temperature resistant metal net that allows flames to pass through without being burned by the flames.

[0032] Usually, cables are inserted into the blocked holes. The presence of cables will affect the filling amount of silica gel in the holes, and thus affect the fireproof sealing effect of silica gel. Therefore, before filling silica gel into the simulated holes, Figure 1 As shown, the user passes the cable through the middle of the limit ring 206 and extends it downward through the placement tube 2 and the extension tube 3 until it passes through the bottom of the placement tube 2. Then, by holding the handwheel 102, the screw 10 is driven to rotate on the threaded tube 9. The screw 10 approaches the cable until the arc-shaped piece 101 contacts the surface of the cable, thereby clamping and fixing the lower end of the cable to prevent the cable from moving during subsequent inspections. Then, the user fills the placement tube 2 and the extension tube 3 with silicone mud, and then starts the inspection work. The user turns on the flamethrower 7 and continuously burns the bottom of the silicone mud in the placement tube 2. The inspection time is the same as the inspection time used for the uninserted cable. When the inspection time is over, the fire protection condition of the silicone mud detected by the uninserted cable is compared to check whether the fire protection condition of the silicone mud is different after the cable is inserted. Then, it is concluded whether the insertion of the cable in the silicone mud has an impact on the fire protection of the silicone mud, and check whether the part of the cable located in the silicone mud is ignited to judge the fire blocking effect of the silicone mud.

[0033] During the detection process of inserted cables, the extension tube 3 is added or removed to simulate the actual situation of cables inserted into holes of different depths, thereby improving the detection diversity. In addition, when the hole depth needs to be reduced, the cable diameter is fixed at this time, and an adaptation groove 61 is opened on the partition plate 6 to adapt to the shape of the cable. When the cable is located in the silicone mud, the partition plate 6 completely fits the surface of the cable through the adaptation groove 61 to separate the silicone mud.

[0034] When a cable is passed through the hole, the end of the cable extending outside the hole will move due to normal human use or inspection of the cable, causing the position where the cable enters the hole to bend and deform. The silicone mud is flexible and plastic in a normal state, and the bending deformation of the cable will squeeze the silicone mud, causing the silicone mud in the hole to deform. Therefore, when the cable is inserted into the silicone mud for inspection, the user can manually move the mounting ring 204, and the mounting ring 204 and the electric push rod 202 move relative to each other through the ball pin 203 as a fulcrum. The electric push rod 202 and the mounting frame 11 are supported by the ball pin 203. 01 is the relative movement of the fulcrum, and the electric push rod 202 is adaptively extended and retracted, so that the mounting ring 204 can move in any direction. The mounting ring 204 will drive the upper part of the cable to move and bend it through the limit ring 206, thereby simulating the situation where the cable is located outside the hole and is moved by external force. At the same time, by controlling the length locking of the electric push rod 202, the position of the mounting ring 204 remains fixed, and the limit ring 206 keeps the cable at the same degree of bending. At this time, the flame is continuously burned to detect the deformation of the silicone mud caused by the different bending degrees of the cable to determine whether it will affect its sealing effect.

[0035] Furthermore, the shallower the hole depth, the less silicone mud is filled. Therefore, under the same bending degree of the cable, the less silicone mud is filled, the easier it is for the bent cable to squeeze and deform, thus losing its sealing performance. Therefore, when testing whether the bending of the cable affects the fireproof performance of the silicone mud, it is necessary to test holes of different depths. The specific operation is as follows: After the user has inserted the partition plate 6 into the silicone mud to separate the upper and lower parts, he pushes the slider 207 to drive the slider 208 away from the cable, then rotates the locking rod 210 to make it away from the slider 207, unlocks the slider 208, and then pushes the slider 208 downward so that the support block 209 is located under the connecting rod 5 of the top extension tube 3. Then, he pushes the slider 207 again to drive the slider 208 toward the cable direction so that the support block 209 is located just below the connecting rod 5. Then, the corresponding slider 208 is locked again by the locking rod 210, and then the electric push rod 202 is controlled to extend upward. The electric push rod 202 pushes the mounting ring 204, and the mounting ring 204 drives the slider 208 to move upward. The support block 209 will support the connecting rod 5 and drive the connecting rod 5 to move upward. The connecting rod 5 drives the extension tube 3 and related parts to move upward, thereby realizing the separation of the extension tube 3 and reducing the depth of the hole. After that, the connecting rod 5 drives the extension tube 3 to rise to a height where the distance between the upper and lower extension tubes 3 is sufficient for the user to operate. Figure 3As shown, at this time, the user moves the mounting ring 204 again, and the two partition plates 6 are still in a state of being close to each other, maintaining contact with the outer surface of the cable, and then the mounting ring 204 drives the extension tube 3, the extension tube 3 drives the partition plate 6, and the partition plate 6 drives the cable to bend, so that the bending point of the cable is closest to the surface of the silicone mud of the middle extension tube 3, ensuring the simulation experiment effect; at the same time, the extension tube 3 is driven to separate by the mounting ring 204, the slide rod 208 and the support block 209 of the bending assembly, and the user does not need to manually operate the extension tube 3 to separate. , and during the separation process of the extension tube 3, the situation of the silicone mud in the placement tube 2 and the extension tube 3 can be better observed. At the same time, the separated extension tube 3 is located on the supporting block 209. When the extension tube 3 needs to be reinstalled on the mounting rod 12 later, it is only necessary to make the mounting ring 204 horizontal. After the extension tube 3 is aligned with the mounting rod 12, the mounting ring 204 is controlled to drive the supporting block 209 to descend. If the extension tube 3 is manually disassembled, due to the existence of the bending assembly, the parts of the bending assembly need to be removed first before the extension tube 3 can be disassembled, which affects the use efficiency.

[0036] It should be noted that when the cable is inserted into the silicone mud and the extension tube 3 is moved upward to separate the silicone mud, the two partition plates 6 are in a closed state to the bottom surface of the extension tube 3, and then the silicone mud in the extension tube 3 is supported and rises together with the extension tube 3 to prevent the silicone mud in the extension tube 3 from falling off. Example 2

[0037] On the basis of Example 1, Figures 9-12 As shown, it also includes an adaptation component, which includes an insert plate 301 and a rotating ring 302; the adaptation groove 61 is set to a rectangle; a storage cavity 62 is opened in each partition plate 6; each partition plate 6 is slidably connected to a plug plate 301 on the side facing the center of the extension tube 3; the plug plate 301 is blocked and can be stored in the corresponding storage cavity 62; a number of springs are connected between the storage cavity 62 and the corresponding plug plate 301; each extension tube 3 is rotatably connected to a rotating ring 302; all guide rods 4 on the same extension tube 3 are fixedly connected to the corresponding rotating ring 302.

[0038] A method for using a silicone-based adhesive sealing performance testing device comprises the following steps: Step 1: Form a simulated hole by placing tube 2 and extension tube 3 on base 1; Step 2: Fill the simulated hole with silica gel for testing. The depth of the simulated hole can be changed by adding or removing the extension tube 3 to obtain simulated holes of different depths for testing. Step 3: Start the flame burner 7 and continue burning the silica gel mud in the simulated hole for 30 minutes, and then observe and test the burned silica gel mud to obtain the fire resistance of the silica gel mud.

[0039] When a cable is passed through the hole, the wire diameter of the cable will be different, and the size of the wire diameter will affect the filling amount of the silicone mud in the hole. Therefore, when placing the cable in the simulated hole, a cable smaller than the diameter of the limit ring 206 can be selected to pass through the simulated hole, and multiple tests can be performed to detect whether the change in the filling amount of silicone mud for cables with different wire diameters will affect the fire prevention effect. At the same time, when performing hole depth change detection, the partition plate 6 needs to adapt to cables with different wire diameters in order to completely layer the silicone mud. Therefore, when the partition plate 6 needs to layer the silicone mud, the user pushes the two partition plates 6 closer to each other through the connecting rod 5. When the straight edge of the semicircular partition plate 6 is inserted into the silicone mud, it is inserted into the silicone mud at the same time, and then the plug plate 301 will contact the cable. When the plug plate 301 contacts the cable, it will be blocked by the cable. As the partition plate 6 is pushed forward, the plug plate 301 will retract into the storage cavity 62. When the plug plate 301 is received in the storage cavity 62, The spring in the corresponding receiving cavity 62 is squeezed, and the reaction force of the spring makes the plug plate 301 keep in contact with the cable; until the straight edges of the two dividing plates 6 contact each other, the plug plate 301 keeps in contact with the cable surface, and the plug plate 301 and the cable surface are in point contact at this time. Some silicone putty in the range covered by the adapter groove 61 is not cut and separated by the plug plate 301. At this time, the user holds the connecting rod 5 to drive the guide rod 4 and the dividing plate 6 to rotate relative to the extension tube 3, and the guide rod 4 drives the rotating ring 302 to rotate on the extension tube 3. At this time, the plug plate 301 in point contact with the cable surface will circle around the outer surface of the cable, thereby forming a circular cutting area covering the position occupied by the adapter groove 61, cutting off the unseparated part of the silicone putty, and then lifting the extension tube 3 upward to separate the silicone putty and reduce the hole depth; thereby, when using cables with different wire diameters for testing, the hole depth adjustment simulation can still be performed simultaneously, thereby improving the practicality of the detection simulation.

[0040] It should be noted that the area of the large rectangle enclosed by the two rectangular adapting grooves 61 is larger than the inner area of the limiting ring 206 , and thus can adapt to the wire diameters of all cables that can pass through the limiting ring 206 .

[0041] Although the present invention has been described in detail with reference to the above embodiments, it will be apparent to those skilled in the art from this disclosure that various changes or modifications may be made to the present invention without departing from the principles and spirit of the invention as defined in the claims. Therefore, the detailed description of the disclosed embodiments is intended to be illustrative only and not to limit the present invention, which is to be defined by the claims.
