Description

Technical Field

[0001] The present invention relates to the technical field of waterproof coating performance testing, in particular to a waterproof coating performance testing device. Background Art

[0002] Waterproof coatings are specialized coatings used to prevent moisture from entering buildings or protecting structures from water damage. They are widely used in residential, commercial, and industrial buildings. During use, waterproof coatings form a protective film to prevent moisture from entering buildings or damaging the structure. Inadequate adhesion between the waterproof coating and the substrate can cause blistering, flaking, or cracking, resulting in loss of waterproofing properties. Therefore, testing the adhesion of waterproof coatings is essential.

[0003] In the prior art, the method of testing the bonding ability of waterproof coatings is mainly through two horizontal substrate plates, and the size of the substrate plate located at the bottom is usually larger than the substrate plate on the upper side. Then a certain thickness of waterproof coating is applied between the two substrate plates. After the waterproof coating is applied, the waterproof coating needs to be cured for a certain time and environment. After the waterproof coating is cured, the upper and lower substrate plates are installed on a pressing device, so that the lower substrate plate is pressed down by the pressing device until the bonding of the waterproof coating fails. The pressing force of the pressing device at this time is recorded, so that the bonding ability of the waterproof coating is tested by the size of the pressing force.

[0004] Although the above detection method can quickly and effectively detect the bonding ability between the waterproof coating and the horizontal substrate board, the waterproof coating can be applied to any position during use. When the waterproof coating is located at a corner, the special structure of the corner will affect the bonding ability of the waterproof coating. Since the substrate board used in the above detection method is horizontal, it is impossible to directly detect the bonding ability of the waterproof coating at the special position of the corner. In addition, during the use of the waterproof coating, the porosity of the substrate will also affect the bonding ability of the waterproof coating, resulting in some waterproof coatings being unable to be applied to substrates with larger porosity. However, the above detection method cannot change the porosity of the substrate board, resulting in an inability to evaluate the bonding ability of the waterproof coating on substrates with larger porosity.

DETAILED DESCRIPTION

[0027] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0028] See Figure 1-Figure 2 A waterproof coating performance testing device includes a base plate 1, a support plate 11 is fixed on the top of the base plate 1, and a limit assembly 12 and a connecting unit 2 are sequentially arranged on the front side of the support plate 11 from top to bottom. The upper and lower parts of the connecting unit 2 are respectively connected to an upper substrate plate 21 and a lower substrate plate 22. An adjusting unit 3 is commonly provided on the upper substrate plate 21 and the lower substrate plate 22. A pushing unit 4 for pushing the lower substrate plate 22 is symmetrically provided on the front side of the support plate 11 and on the left and right sides of the lower substrate plate 22.

[0029] The present invention applies and maintains the waterproof coating through the upper substrate plate 21 and the lower substrate plate 22, and then pushes the lower substrate plate 22 through the pushing unit 4 to detect the bonding ability of the waterproof coating. At the same time, the porosity of the upper substrate plate 21 and the lower substrate plate 22 can be adjusted respectively through the adjusting unit 3, so as to detect whether the bonding ability of the waterproof coating meets the use requirements when the substrate porosity is different.

[0030] Specifically, the upper substrate plate 21 and the lower substrate plate 22 are first removed from the connecting unit 2, and then a certain thickness of waterproof coating is applied between the upper substrate plate 21 and the lower substrate plate 22. After the waterproof coating is applied, the upper substrate plate 21 and the lower substrate plate 22 are placed together with the waterproof coating in a curing device for curing. After the upper substrate plate 21 and the lower substrate plate 22 are cured and connected through the waterproof coating, the upper substrate plate 21 and the lower substrate plate 22 are installed on the connecting unit 2 at the same time, and then the lower substrate plate 22 is pushed downward by the pushing unit 4, so that the bonding ability of the waterproof coating is evaluated by the pushing of the lower substrate plate 22 by the pushing unit 4.

[0031] See Figure 1 、 Figure 2 and Figure 4 The upper substrate plate 21 and the lower substrate plate 22 are both L-shaped, and the vertical and horizontal sections of the two are at 45 degrees to the vertical direction. The length of the upper substrate plate 21 is smaller than the length of the lower substrate plate 22; the limiting assembly 12 includes a front extension plate 121 fixed to the front side of the support plate 11, and a connecting block 122 is slidably passed through the front extension plate 121. A fixing plate 123 is fixed to the top of the rear side of the connecting block 122, and a connecting stud 124 is rotatably installed on the top of the front extension plate 121. The connecting stud 124 is threadedly connected to the fixing plate 123, and a right-angle pressure block 125 is fixed to the bottom of the connecting block 122.

[0032] The connecting unit 2 includes a positioning key 23 fixed on the lower side of the front extension plate 121; a vertical slide rail 24 is fixed on the front side of the support plate 11 and below the positioning key 23, and an embedded rod 241 is connected to the vertical slide rail 24 through a vertical slider, and an outer rod 242 is fixed on the rear side of the lower base plate 22 and is slidably mounted on the embedded rod 241.

[0033] In this embodiment, if Figure 4 As shown, the positioning key 23 is composed of an embedded column and an outer column, and a horizontal pin slides through the embedded column and the outer column.

[0034] By using the L-shaped upper substrate plate 21 and the lower substrate plate 22 as substrates for the waterproof coating to be bonded, the corner position in the actual waterproof coating usage environment is simulated, and the bonding ability of the waterproof coating under special conditions is tested. The connecting unit 2 and the limiting assembly 12 are used to position and stabilize the upper substrate plate 21 and the lower substrate plate 22, thereby ensuring that the upper substrate plate 21 and the lower substrate plate 22 will not be displaced or rotated as a whole when the pushing unit 4 pushes the lower substrate plate 22, thereby ensuring the accuracy and validity of the experimental results.

[0035] Specifically, first pull out the horizontal pin, then release the interlocking action of the embedded column and the outer sleeve column, thereby releasing the positioning function of the positioning key 23, and remove the upper substrate plate 21, then directly pull the lower substrate plate 22 forward from the outer sleeve rod 242 and remove it directly. After the upper substrate plate 21 and the lower substrate plate 22 are removed, place the lower substrate plate 22 in the coating position and apply a specified thickness of waterproof coating on the upper side of the lower substrate plate 22 corresponding to the position range of the upper substrate plate 21 to achieve the best working state of the waterproof coating. Then immediately place the lower side of the upper substrate plate 21 on the lower substrate plate 22 and correspond to the position of the waterproof coating. Then, wait for the waterproof coating to solidify and the lower substrate plate 22 coated with the waterproof coating to be cured for a sufficient time.

[0036] After the maintenance is completed, the upper substrate plate 21 and the lower substrate plate 22 coated with waterproof coating are connected to the connecting unit 2 through the positioning key 23 and the embedded rod 241 and the outer rod 242, and the connecting block 122 is moved downward by rotating the connecting stud 124 until the right-angle pressure block 125 completes the pressure limit on the upper substrate plate 21.

[0037] See Figure 6-Figure 7 The pushing unit 4 includes a mounting plate 41 fixed to the front side of the support plate 11. A pushing element 42 and a transmission element 43 are respectively provided on the side of the mounting plate 41 close to the connection unit 2. The pushing element 42 includes a cylinder 421 fixed to the side of the mounting plate 41 close to the connection unit 2. The pushing end of the cylinder 421 is fixed to the pushing plate 422. A horizontal slide bar 423 is slidably passed through the mounting plate 41 and located above the cylinder 421. A circular plate 424 is fixed to the end of the horizontal slide bar 423 away from the connection unit 2. A horizontal spring is connected between the circular plate 424 and the mounting plate 41. A trapezoidal block 425 is fixed to the end of the horizontal slide bar 423 close to the connection unit 2. The trapezoidal block 425 is provided with a push structure.

[0038] The pushed structure includes an L-shaped connecting plate 426 fixed on the top of the trapezoidal block 425. A vertical stud 427 is threadedly connected to the horizontal section of the L-shaped connecting plate 426. An inner plate 428 is rotatably installed at the bottom of the vertical stud 427, and the inner plate 428 slides through the trapezoidal block 425; a vertical plate 429 is fixed on the top of the pushing plate 422.

[0039] See Figure 3 、 Figure 6 and Figure 7The transmission element 43 includes an inner extension plate 431 fixed on the mounting plate 41 and located on the rear side of the pushing element 42. A horizontal slide rail is fixed on the inner extension plate 431 near the lower substrate plate 22. A front extension column 432 is connected to the horizontal slide rail through a horizontal slider. A coordinating bevel block 433 is fixed to the front end of the front extension column 432. A pushed block 434 is slidably connected to the coordinating bevel block 433. A locking structure for locking the front extension column 432 is provided on the horizontal slide rail; the coordinating bevel block 433 and the pushed block 434 are jointly provided with a positioning structure for positioning the pushed block 434, and a pressure sensor is provided on the side of the pushed block 434 near the lower substrate plate 22.

[0040] In this embodiment, if Figure 3 As shown, in order to accurately measure the distance between the transfer element 43 and the push plate 422 , a scale needs to be fixed on the side of the transfer element 43 close to the push plate 422 .

[0041] The pushing unit 4 is used to push the lower substrate plate 22 by pushing forces in different directions, and the pushed state of the trapezoidal block 425 can be quickly switched through the pushed structure, and then the direction of the pushing force can be quickly switched, so that the transmission element 43 can push the lower substrate plate 22 with pushing forces in different directions, making the detection method more diversified. At the same time, the transmission element 43 can cooperate with the pushing element 42 to push the lower substrate plate 22 with pushing forces in different directions, thereby detecting the bonding ability of the waterproof coating under shear force and downward thrust.

[0042] Specifically, after the installation and positioning of the upper substrate plate 21 and the lower substrate plate 22 are completed, the vertical stud 427 on the left is rotated first, so that the inner panel 428 on the left moves downward, and the positioning structure releases the positioning effect of the pushed block 434 and the coordinated inclined block 433. At the same time, all the holes on the upper substrate plate 21 and the lower substrate plate 22 are closed by the adjustment unit 3, and then the cylinder 421 on the left is controlled to drive the push plate 422 to move toward the lower substrate plate 22. At this time, the push plate 422 will push the inner panel 428, thereby pushing the trapezoidal block 425 toward the lower substrate plate 22. The plate 22 moves, causing the trapezoidal block 425 to push the pushed block 434, thereby pushing the pushed block 434 with a force perpendicular to the lower substrate plate 22, thereby testing the bonding ability of the waterproof coating under the action of shear force. After the pressure sensor reaches the specified value, the data on the scale at this moment is recorded, that is, the distance between the pushing plate 422 and the front extension column 432. The distance between the pushing plate 422 and the front extension column 432 indicates the distance the lower substrate plate 22 moves after the waterproof coating produces elastic deformation when subjected to a shear force of a specified magnitude.

[0043] After the data recording of the scales on the left and right sides is completed, the two vertical studs 427 are rotated at the same time, and the two embedded plates 428 are moved upward synchronously, and the positioning structure is restored to the positioning effect of the pushed block 434 and the coordinated inclined block 433, and the locking effect of the locking structure is released at the same time. Then, the two cylinders 421 are synchronously controlled to drive the push plate 422 to move toward the lower substrate plate 22, and the push plate 422 will directly push the front extension column 432 and push the lower substrate plate 22, thereby pushing the lower substrate plate 22 at the same time through the two pushed blocks 434 until the lower substrate plate 22 is separated from the upper substrate plate 21 due to the pushed blocks 434, that is, the waterproof coating At the moment of adhesion failure, the pressure of the pressure sensor at this time is recorded, and then the thrust exerted on the lower substrate plate 22 is calculated based on the pressure sensor. The thrust is compared with the thrust of adhesion failure of the waterproof coating between the two horizontal substrates. If the calculated thrust exerted on the lower substrate plate 22 is significantly smaller than the thrust of adhesion failure of the waterproof coating between the two horizontal substrates, it indicates that the adhesion ability of the waterproof coating at the corner position is poor. If the difference between the calculated thrust exerted on the lower substrate plate 22 and the thrust of adhesion failure of the waterproof coating between the two horizontal substrates is within the allowable range, it indicates that the adhesion ability of the waterproof coating at the corner position meets the use requirements.

[0044] When the adhesion test of the waterproof coating to be tested at the corner position is completed and meets the use requirements, if it meets the requirements, the upper substrate plate 21 and the lower substrate plate 22 are removed from the connecting unit 2, and then the waterproof coating on the upper substrate plate 21 and the lower substrate plate 22 is completely eliminated by physical scraping and chemical dissolution. After the elimination is completed, the number of holes in the right half of the upper substrate plate 21 and the lower substrate plate 22 is changed by the adjustment unit 3, and then the waterproof coating is applied again. After the coating is completed, the upper substrate plate 21 and the lower substrate plate 22 are installed in place and pushed again by a force perpendicular to the lower substrate plate 22 to simultaneously control the left and right sides. The cylinder 421 drives the pushing plate 422 and pushes the pushed block 434 to push perpendicularly to the lower substrate plate 22, and records the data of the scales on the left and right sides at this moment, and then repeats the above-mentioned removal of the waterproof coating and the application of the new waterproof coating. Before the application of the new waterproof coating, the number of holes in the right half of the upper substrate plate 21 and the lower substrate plate 22 is changed by the adjustment unit 3, and then the upper substrate plate 21 and the lower substrate plate 22 are installed again. After the installation of the two is completed, the cylinder 421 on the right is controlled to drive the pushing plate 422 and push the pushed block 434 to push perpendicularly to the lower substrate plate 22, and record the data of the scale on the right side at this moment.

[0045] After the data recording is completed, the data recorded on the left side of the scale are compared, and the data recorded on the right side of the scale are compared. If the data recorded on the scale on either side after the pressure sensor reaches the specified value is significantly different after comparison, it indicates that the bonding ability of the waterproof coating is significantly poor, that is, the porosity of the substrate has a greater impact on the bonding ability of the waterproof coating. If the data recorded on the scale on either side after the pressure sensor reaches the specified value is not much different after comparison, it indicates that the bonding ability of the waterproof coating is almost not affected by the porosity of the substrate.

[0046] It should be noted that when testing the waterproof coating to be tested, a horizontal substrate needs to be used for control testing. The equipment used for the control testing of the horizontal substrate is relatively common and widely used in the actual testing process, so it will not be described in detail. The area of ​​the horizontal substrate used for control testing should be equal to the area of ​​the lower side of the upper substrate plate 21.

[0047] In this embodiment, if Figure 6 As shown, the locking structure includes an L-shaped upper extension plate 435 fixed on the top of the horizontal slide rail, a locking hole is provided in the horizontal section of the L-shaped upper extension plate 435, and an alignment hole is provided in the middle of the front extension column 432 at a position corresponding to the locking hole. The locking hole and the alignment hole are commonly connected with a positioning pin, and the positioning structure includes an alignment seat arranged at the corresponding positions of the coordinating inclined block 433 and the pushed block 434, and an oblique pin is commonly connected between the two alignment seats.

[0048] See Figure 4-Figure 5 The adjusting unit 3 includes a plurality of groups of circular holes 31 that are symmetrically and evenly arranged on the upper substrate plate 21. The upper substrate plate 21 is connected to a filling rod 311 corresponding to the position of the circular hole 31 through a symmetrically arranged step-by-step adjusting element 32. The filling rod 311 is driven by the step-by-step adjusting element 32 to fill the circular hole 31 step by step and adjust the porosity of the upper substrate plate 21; the lower substrate plate 22 is symmetrically and evenly provided with a plurality of groups of evenly distributed sliding holes 312. The sliding holes 312 correspond to the positions of the circular holes 31. Each sliding hole 312 is slidably connected with an oblique sliding rod 313, and all the oblique sliding rods 313 on the lower substrate plate 22 are commonly connected to a synchronization rod 314, and a position adjustment structure is provided between the synchronization rod 314 and the lower substrate plate 22; the position adjustment structure includes a coordination plate 315 fixed to the bottom of the lower substrate plate 22, and the coordination plate 315 is provided with two positioning holes, and a locking seat 316 is fixed to the position of the synchronization rod 314 near the coordination plate 315, and a locking pin is connected between the locking seat 316 and the positioning hole at the corresponding position.

[0049] The step-by-step adjustment element 32 includes elastic telescopic rods fixed symmetrically on the top of the upper substrate plate 21 on the left and right sides. The telescopic ends of the two elastic telescopic rods are commonly connected to an inclined plate 321. A T-shaped rod 322 is fixed to the bottom of the inclined plate 321. The horizontal section of the T-shaped rod 322 is connected to the filling rods 311 on the left and right sides. The filling rods 311 in the middle position are commonly connected to a connecting rod 323. A pressure block 324 that slides through the inclined plate 321 is fixed on the top of the connecting rod 323. A triangular block 325 is fixed on the top of the inclined plate 321. A pressing structure is provided on the upper substrate plate 21; the pressing structure includes an L-shaped limit plate 326 fixed to the upper substrate plate 21 and arranged obliquely. The vertical section of the L-shaped limit plate 326 is slidably connected to a pressing block 327. The vertical section of the L-shaped limit plate 326 is also threadedly connected to an adjusting stud 328. The adjusting stud 328 and the pressing block 327 are rotatably connected.

[0050] The adjustment unit 3 is used to adjust the porosity of the lower substrate plate 22 and the upper substrate plate 21, so as to test the influence of substrates with different porosities on the bonding ability of the waterproof coating. At the same time, the porosity of the upper substrate plate 21 can be adjusted multiple times through the step-by-step adjustment element 32, so that the upper substrate plate 21 and the lower substrate plate 22 with different porosities can be combined and tested through multiple adjustments, thereby making the test data diverse and avoiding the occurrence of accidental test results due to too little test data.

[0051] Specifically, before controlling the pushing element 42 and the transmission element 43 to push the lower substrate plate 22, first control the adjusting screw 328 to rotate, so that the triangular block 325 is pressed by the pressing block 327, and then the circular hole 31 is closed by the filling rod 311, and the porosity of the upper substrate plate 21 is adjusted by controlling the number of holes on the upper substrate plate 21. If it is necessary to continue to adjust the porosity of the upper substrate plate 21, continue to rotate the adjusting screw 328, so that the pressing block 327 presses the pressure block 324, and then the pressure block 324 drives the connecting rod 323 and the filling rod 311 in the middle position to continue to close the circular hole 31, and further adjust the porosity of the upper substrate plate 21.

[0052] If the porosity of the lower substrate plate 22 needs to be adjusted, it is only necessary to adjust the position of the synchronization rod 314 and the oblique sliding rod 313 through the position adjustment structure, so that the oblique sliding rod 313 fully fills the sliding hole 312, thereby achieving the purpose of adjusting the porosity of the lower substrate plate 22. By adjusting the porosity of the lower substrate plate 22 and the upper substrate plate 21 multiple times and combining them with each other, it is sufficient to obtain a number of test results that avoid test contingency and test deviation.

[0053] By changing the number of holes in the lower substrate plate 22 and the upper substrate plate 21 , the ratio of the number of holes to the substrate volume is adjusted, thereby changing the porosity of the lower substrate plate 22 and the upper substrate plate 21 .

[0054] The working steps of the present invention are as follows: the first step is to release the positioning function of the positioning key 23 and remove the upper substrate plate 21, then directly pull the lower substrate plate 22 forward from the outer rod 242 and remove it directly. After the removal is completed, the lower substrate plate 22 is placed in the coating position and a specified thickness of waterproof coating is coated on the upper substrate plate 21 to achieve the best working state of the waterproof coating. Then, the upper substrate plate 21 is immediately placed on the lower substrate plate 22, and then the upper substrate plate 21 and the lower substrate plate 22 coated with the waterproof coating are successively allowed to wait for the waterproof coating to solidify and be cured for a sufficient time.

[0055] In the second step, after the maintenance is completed, the upper substrate plate 21 and the lower substrate plate 22 coated with waterproof coating are connected to the connecting unit 2 through the positioning key 23 and the embedded rod 241 and the outer rod 242, and the connecting block 122 is moved downward by rotating the connecting stud 124 until the right-angle pressure block 125 completes the pressure limit on the upper substrate plate 21.

[0056] In the third step, after the upper substrate plate 21 and the lower substrate plate 22 are installed and positioned, the vertical stud 427 on the left is rotated first, so that the inner embedded plate 428 on the left moves downward, and the positioning structure releases the positioning effect of the pushed block 434 and the coordinated inclined block 433. At the same time, all the holes on the upper substrate plate 21 and the lower substrate plate 22 are closed by the adjustment unit 3, and then the cylinder 421 on the left is controlled to drive the pushing plate 422 to move toward the lower substrate plate 22. At this time, the pushing plate 422 will push the inner embedded plate 428, thereby pushing the trapezoidal block 425 to move toward the lower substrate plate 22, and then the trapezoidal block 425 pushes the pushed block 434, so that the pushed block 434 pushes with a force perpendicular to the lower substrate plate 22, thereby testing the bonding ability of the waterproof coating under the action of shear force. After the pressure sensor reaches the specified value, the data of the scale at this moment is recorded.

[0057] In the fourth step, after the data recording of the scales on the left and right sides is completed, the two vertical studs 427 are rotated at the same time, and the two embedded plates 428 are moved upward synchronously, and the positioning structure is restored to the positioning effect of the pushed block 434 and the coordinated inclined block 433, and the locking effect of the locking structure is released at the same time. Then, the two cylinders 421 are synchronously controlled to drive the push plate 422 to move toward the lower substrate plate 22. The push plate 422 will directly push the front extension column 432 and push the lower substrate plate 22, thereby pushing the lower substrate plate 22 at the same time through the two pushed blocks 434 until the lower substrate plate 22 is separated from the upper substrate plate 21 due to the pushed blocks 434, that is, the moment when the bonding of the waterproof coating fails, the pressure of the pressure sensor at this time is recorded, and the bonding failure thrust of the waterproof coating is calculated based on the pressure of the pressure sensor, so as to evaluate whether the waterproof coating meets the use requirements.

[0058] In the fifth step, when the adhesion test of the waterproof coating to be tested at the corner position is completed and meets the use requirements, if it meets the requirements, the upper substrate plate 21 and the lower substrate plate 22 are removed from the connecting unit 2, and then the waterproof coating on the upper substrate plate 21 and the lower substrate plate 22 is completely eliminated by physical scraping and chemical dissolution. After the elimination is completed, the number of holes in the right half of the upper substrate plate 21 and the lower substrate plate 22 is changed by the adjustment unit 3, and then the waterproof coating is applied again. After the coating is completed, the upper substrate plate 21 and the lower substrate plate 22 are installed in place and pushed again by a thrust perpendicular to the lower substrate plate 22, while controlling the cylinders 421 on the left and right sides to drive the pushing plate 422 and push the pushed block 434. Push perpendicularly to the lower substrate plate 22, record the data of the scales on the left and right sides at this moment, then repeat the above-mentioned removal of waterproof coating and application of new waterproof coating. Before applying the new waterproof coating, change the number of holes in the right half of the upper substrate plate 21 and the lower substrate plate 22 through the adjustment unit 3, then install the upper substrate plate 21 and the lower substrate plate 22 again. After the installation of the two is completed, control the cylinder 421 on the right to drive the pushing plate 422 and push the pushed block 434 perpendicular to the lower substrate plate 22, and record the data of the scale on the right side at this moment. The data recorded on the left scale and the data on the right scale are used to evaluate the influence of porosity on the bonding ability of the waterproof coating.
