Description

Technical Field

[0001] This utility model relates to the field of hydrolysis resistance testing technology, specifically a device for testing the hydrolysis resistance of hot-melt road marking paint film. Background Technology

[0002] With the booming development of transportation, the demand for road marking paint is increasing. Hot-melt road marking paint is widely used due to its advantages such as rapid construction and nighttime reflectivity. However, the hydrolysis resistance of the paint film is crucial, directly affecting its service life in complex climatic environments. If the hydrolysis resistance is poor, in rainy and humid areas or environments subjected to prolonged water immersion, the paint film may peel off or powder, severely affecting the clarity and legibility of road markings, and thus posing a threat to traffic safety.

[0003] Currently, while a preliminary device for testing the hydrolysis resistance of hot-melt road marking paint films has been developed, it suffers from numerous shortcomings. The handling of film samples is particularly inconvenient. Traditional devices typically employ fixed clamping mechanisms, making subsequent sample handling extremely cumbersome once the sample is positioned. Multiple tools and complex procedures are required for each replacement, consuming significant time and manpower, and potentially damaging the sample due to improper handling, thus affecting test accuracy. Furthermore, this inconvenient design impacts testing efficiency, becoming increasingly problematic when frequent replacement of different batches and specifications of samples is needed for comparative analysis, significantly hindering the smooth progress of hot-melt road marking paint research and quality testing.

[0004] Based on this, a device for testing the hydrolysis resistance of hot-melt road marking paint film is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

In use, a hydrolysis solution is added into the cylinder 101 through the water inlet 104. During the hydrolysis reaction, the temperature and pressure inside the cylinder 101 are monitored in real time by the temperature sensor 500 and the pressure sensor 600. When the temperature drops, the electric heating tube is activated to heat up the temperature. When the pressure is too high, the pressure relief valve 105 is activated to relieve the pressure. After the hydrolysis reaction is completed, the hydrolysis solution is discharged through the drain port 103.

[0027] In one embodiment, such as Figure 1 As shown, the lifting assembly 200 includes a base 201 disposed on the outside of the cylinder 101, a cylinder 202 disposed on the base 201, a push rod 203 disposed at the output end of the cylinder 202, and the upper end of the push rod 203 being fixedly connected to the cylinder cover 102. In use, the cylinder 202 drives the push rod 203 to move up and down, thereby controlling the opening and closing of the cylinder cover 102.

[0028] In one embodiment, such as Figure 3 As shown, the placement rack 300 includes a fixing rod 301, the upper end of which is fixed to the lower end of the cylinder cover 102.

Then the pressing part 309 is released, and the film sample is clamped by the clamping part 308 and the frame 304. Then the film fixing frame with the film sample is fixed to the mounting column 303 by the C-shaped card seat 305.

[0029] In one embodiment, such as Figure 4As shown, the stirring assembly 400 includes a gear ring 401 rotatably connected to the lower end of the cylinder cover 102.

[0030] The above embodiments disclose a device for testing the hydrolysis resistance of hot-melt road marking paint film. In use, a hydrolysis solution is added to the cylinder 101 through the inlet 104. The hydrolysis solution in the cylinder 101 is heated by an electric heating tube. Then, the pressing part 309 is pressed, placing the film sample between the clamping part 308 and the frame 304. The pressing part 309 is then released, and the film sample is clamped between the clamping part 308 and the frame 304. The film fixing frame with the film sample is then fixed to the mounting column 303 via a C-shaped bracket 305. Finally, the cylinder 202 drives the push rod 203 downwards, moving the cylinder cover 102 and the placement rack 303 downwards. The cylinder 102 is closed simultaneously. During the hydrolysis reaction, the second gear 405 is driven to rotate by the motor 406, which in turn drives the gear ring 401 to rotate. At the same time, the gear ring 401 and the first gear 403 mesh to drive the rotating shaft 402 to rotate, thereby driving the stirring blade 404 to rotate and stir the hydrolysis solution. Meanwhile, the temperature and pressure inside the cylinder 101 are monitored in real time by the temperature sensor 500 and the pressure sensor 600. When the temperature drops, the electric heating tube is activated to heat up the temperature. When the pressure is too high, the pressure relief valve 105 is activated to relieve the pressure.
