Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0028] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0029] Example 1

[0030] Reference Figures 1 to 6 , which is the first embodiment of the present utility model, and provides a fire retardant coating adhesion strength detection device. The fire retardant coating adhesion strength detection device includes a heating component 100, including a heat-insulating shell 101, a heat-insulating cover 102 and a heating plate 103. The heating plate 103 is fixed to the bottom of the inner wall of the heat-insulating shell 101, and the heat-insulating cover 102 is slidably connected to the surface of the heating plate 103.

[0031] The heat-insulating shell 101 is used to protect things outside the device during heating and to better stabilize the temperature. The heat-insulating cover 102 is used to prevent the temperature from overflowing during the heating process. The heating plate 103 is used to heat the fire-retardant coating. A heating coil is provided in the heating plate 103. The heating principle is existing technology, and the heating plate 103 can be purchased on the market.

[0032] The test assembly 200 is arranged inside the thermal insulation shell 101, including a support member 201, which is arranged above the heating plate 103, and includes a heating base 201a attached to the upper surface of the heating plate 103. A test groove 201a-1 is provided on the upper surface of the heating base 201a. A support column 2021b is also fixedly connected to the upper surface of the heating base 201a. A support ring 201c is fixedly connected to the top of the support column 2021b. The surface of the support ring 201c is attached to the inner wall of the thermal insulation shell 101. A pull plate 201d is slidingly arranged inside the heating base 201a, and a lower test plate 201e is placed on the groove on the surface of the pull plate 201d.

[0033] The heating base 201a is used to fix the position of the pull plate 201d so that the lower test plate 201e in the pull plate 201d can be heated evenly. The opened test groove 201a-1 is used to test the paint on the lower test plate 201e. The fixedly connected support column 2021b and support ring 201c are used to fix the entire test device to prevent displacement.

[0034] Specifically, the test assembly 200 also includes a clamping member 202, which is arranged above the test slot 201a-1. The clamping member 202 includes an upper test plate 202a arranged above the lower test plate 201e. A clamping plate 202b is provided on the surface of the upper test plate 202a, and a card slot 202b-1 is opened on the outer wall of the clamping plate 202b.

[0035] The upper test plate 202a can be placed in the slot 202b-1 of the clamping plate 202b, so that the upper test plate 202a is aligned with the test slot 201a-1 below, so that the upper test plate 202a and the lower test plate 201e can be aligned during the descending process. The slot 202b-1 and the pull plate 201d restrict the upper test plate 202a and the lower test plate 201e, so that the overlapping area of ​​the upper test plate 202a and the lower test plate 201e is maintained constant, reducing the impact on the bonding strength during the test. The upper test plate 202a and the lower test plate 201e are both cut from base materials, and the bonding strength of different base materials and the same fire retardant coating is different.

[0036] Specifically, the test assembly 200 also includes a tensile member 203, which is arranged at the top of the clamping plate 202b. The tensile member 203 also includes a spring 203a whose end is fixed to the top of the clamping plate 202b. The other end of the spring 203a is fixedly connected to a tension sensor 203b. A conductive wire 203d is provided on the tension sensor 203b, and the other end of the conductive wire 203d is connected to a digital display screen 203e. A placement groove 201c-1 is also provided on the upper surface of the support ring 201c, and the tension digital display screen 203e is placed in the placement groove 201c-1.

[0037] The tensile member 203 is used to perform a tensile test after the upper test plate 202a and the lower test plate 201e are pasted with paint, so as to detect the adhesion strength of the paint. When the spring 203a is deformed, the generated tension is sensed by the tension sensor 203b and transmitted to the digital display screen 203e through the conductive line 203d. The tension digital display screen 203e is equipped with a processor, which can process the transmitted data and display it on the digital display screen 203e. The placement slot 201c-1 is used to place the tension digital display screen 203e, so that the tension digital display screen 203e can display the current tension.

[0038] Specifically, a rotating shaft 203f is fixedly connected to the top of the tension sensor 203b, and a blocking cap 203g is fixed to the top of the rotating shaft 203f.

[0039] The rotating shaft 203f is used to transmit the pulling force on the tensile member 203, and the blocking cap 203g is used to prevent the rotating shaft 203f from excessive rotation.

[0040] Example 2

[0041] Reference Figures 1 to 6 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0042] Specifically, the test assembly 200 also includes a limit member 204, which is arranged on the outer wall of the clamping plate 202b. The limit member 204 includes a limit ring 204a sliding on the surface of the clamping plate 202b. A limit column 204b is fixed on the top of the limit ring 204a, and a retaining ring 204c is fixed on the top of the limit column 204b.

[0043] Through the limiting ring 204a, the limiting column 204b and the retaining ring 204c, the limiting ring 204a can squeeze the top of the upper test plate 202a during the stretching process, so that the upper test plate 202a is firmly squeezed into the clamping plate 202b, preventing the upper test plate 202a from moving relative to the clamping plate 202b. In particular, for substrates with relatively high elasticity, the squeezing of the limiting ring 204a can improve the stability of the substrate in the clamping plate 202b.

[0044] Specifically, a top plate 204d is fixed on the top of the support ring 201c. A sliding hole 204d-1 is opened on the upper surface of the top plate 204d. The limiting column 204b is slidably connected to the sliding hole 204d-1.

[0045] The top plate 204d also has the function of isolating temperature. The sliding hole 204d-1 provided therein limits the sliding of the limiting column 204b, thereby ensuring the stability of the limiting ring 204a during the lifting process.

[0046] Specifically, a sleeve 204e is fixed to the upper surface of the top plate 204d, a sleeve 204f is rotatably connected to the inner wall of the sleeve 204e, and a rotating handle 204g is fixedly connected to the outer wall of the sleeve 204f.

[0047] The sleeve 204e is used to fix the sleeve 204f, and the handle 204g is used to drive the sleeve 204f to rotate. The inner wall of the sleeve 204f is provided with a threaded groove that cooperates with the rotating shaft 203f, so that when the sleeve 204f rotates, the rotating shaft 203f can be driven to move up and down.

[0048] Specifically, the top of the heat-insulating shell 101 and the top plate 204d are fixedly connected.

[0049] The heat-insulating outer shell 101 and the top plate 204d are sealed to prevent heat from escaping, thereby allowing the fire-retardant coating on the substrate to be heated quickly.

[0050] Example 3

[0051] Reference Figures 1 to 6 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0052] Specifically, a temperature digital display screen 101a is fixed on one side of the heat-insulating shell 101, a temperature measuring groove 201a-2 is opened in the heating base 201a, a temperature measuring probe 10b is set in the temperature measuring groove 201a-2, and the temperature digital display screen 101a and the temperature measuring probe 10b are electrically connected.

[0053] The temperature measuring probe 10b is located in the temperature measuring tank 201a-2 to measure the temperature more accurately. The temperature digital display screen 101a is electrically connected to the temperature measuring probe 10b and can display the detected temperature.

[0054] Specifically, a handle 104 is provided on the surface of the thermal insulation cover 102 .

[0055] The handle 104 is provided to facilitate removal of the insulation cover 102 , thereby allowing operation on the upper test plate 202 a and the lower test plate 201 e in the insulation housing 101 .

[0056] When in use, first apply fire retardant paint on the upper surface of the lower test plate 201e, then place it on the surface notch of the pull plate 201d, push the pull plate 201d into the heating base 201a, and then put the upper test plate 202a into the slot 202b-1 of the clamping part 202, rotate the handle 204g connected to the outer wall of the sleeve 204f, move the upper test plate 202a downward to the top of the lower test plate 201e, and make contact with the fire retardant paint. Let the paint stand and wait for it to dry, then seal the insulation cover 102 with the handle 104 to the insulation shell 101, then start the heating plate 103, observe the data on the temperature digital display 101a, and the temperature of the temperature probe 10b at this time is the temperature environment of the lower test plate 201e. When it reaches When the detection temperature is reached, the heating plate is turned off, and the handle 204g connected to the outer wall of the sleeve 204f is rotated to provide an upward pulling force to the upper test plate 202a, pulling it away from the lower test plate 201e. At this time, the tension data is collected through the tension sensor 203b at the top of the spring and transmitted to the tension digital display screen 203e through the conduction line 203d. When the upper test plate 202a is separated from the lower test plate 201e, the tension data on the tension digital display screen 203e is the test tension limit. At this time, the contact area between the upper test plate 202a and the lower test plate 201e is the test area. After standing for cooling, open the insulation cover 102 to take out the upper test plate 202a, pull out the pull plate 201d, take out the lower test plate 201e, and the test is completed.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
