Description

Technical Field

[0001] The invention relates to the technical field of coating wear detection, in particular to a road surface colored anti-skid water-based coating wear performance test device and method. Background Art

[0002] Color anti-skid water-based coating wear performance test equipment usually consists of wear test equipment, displacement equipment, protective equipment and clamping equipment, and the test objects are mostly standard coating samples.

[0003] The patent with patent announcement number CN220690729U relates to a pavement coating wear performance tester, including a base; the top of the base is fixedly connected to the bottom of the tester body, the top of the base is provided with a first groove, the bottom of the first groove is fixedly connected to the bottom of the placement table, and an adjustable fixing mechanism is provided between the base and the placement table; the adjustable fixing mechanism includes threaded holes, and the threaded holes are both provided on both sides of the base; through the design of the adjustable fixing mechanism, the function of fixing the pavement coating on all sides at the same time is realized, which solves the problem that the existing tester only clamps and fixes the two sides of the pavement coating, but does not fix the front and rear ends of the pavement coating. Since the test is carried out by rotating friction on the surface of the pavement coating, it is very easy for the pavement coating to detach during the test, thereby improving stability.

[0004] In the above patent, the function of fixing the pavement coating on all sides at the same time is achieved through the design of an adjustable fixing mechanism, which solves the problem that the existing test instrument only clamps and fixes the pavement coating on both sides. However, it is difficult to prevent the fastening plate from excessively clamping the coating sample. Excessive clamping will cause the coating sample to be subjected to excessive compression or bending, resulting in cracking of the coating and thus affecting the accuracy of the test results. Excessive clamping will also cause abnormal wear of the coating sample, further affecting the authenticity of the test results. Summary of the invention

[0014] A method for testing the abrasion performance of a colored anti-skid water-based coating on a road surface, using the above-mentioned device for testing the abrasion performance of a colored anti-skid water-based coating on a road surface, comprises the following steps: Step 1: Place the coating sample to be tested into the testing tank, which can prevent the coating sample to be tested from being excessively tilted; Step 2: After the coated sample is placed inside the test tank, the electric push rod drives the fastening plate to move away from the U-shaped frame. After the coated sample is fixed by the fastening plate, the displacement device is started to operate, and the displacement device drives the T-shaped frame to move downward; Step 3: The T-shaped frame moves downward to drive the wear test equipment to move downward, and the wear test equipment moves downward to contact the coating sample and operate synchronously, and the wear test equipment operates synchronously to perform a wear test on the coating sample; Step 4: After the wear test is completed, measure the weight difference of the coating sample before and after wear by weighing or use an altimeter to measure the wear depth or roughness change of the coating surface.

[0015] The present invention provides a road surface colored anti-skid water-based coating wear performance test equipment, which has the following beneficial effects: (1) The invention can prevent the coating sample to be tested from being excessively tilted by means of the detection groove. The detection groove can prevent the coating sample from being tilted, and can ensure that the coating sample is maintained at a specified angle during the test, thereby obtaining more accurate and reliable test data. The fastening plate is limited by the contact between the free end of the elastic telescopic rod and the protective groove. The fastening plate is limited by the elastic telescopic rod and cannot continue to squeeze the coating sample. If the fastening plate applies too much clamping force, it will cause abnormal wear, and thus the wear resistance of the coating sample cannot be truly reflected. By limiting excessive squeezing, it can ensure that the coating sample is subjected to force in a manner that is more in line with actual usage during the test, thereby obtaining more accurate wear performance data.

[0016] (2) The invention drives the stabilizing frame to move by moving the stabilizing plate away from the detection frame. The stabilizing frame moves away from the detection frame to squeeze the protective spring. The stabilizing frame moves to contact the top of the coating sample and presses the top of the coating sample to limit the position. The contact and pressure between the stabilizing frame and the top of the coating sample can help ensure that the coating sample maintains a stable position during the test and prevent the coating sample from shifting or tilting during the test, which helps to improve the accuracy and reliability of the test. The linkage rod moves to cooperate with the stabilizing frame to partially block the top of the detection slot. By partially blocking the top of the detection slot, splashes during the test can be effectively reduced to avoid damage to the surrounding environment and personnel.

[0017] (3) The invention generates negative pressure inside the L-shaped tube so that the limit plate moves upward under the action of the negative pressure inside the L-shaped tube. The limit plate moves upward and drives the limit rod to move. The limit rod moves upward to break away from the contact with the limit groove and release the limit on the button. The button can be pressed manually only after the limit of the button is released. The wear test equipment can be started only after it is detected that the coating sample is clamped stably, ensuring that the coating sample will not loosen during the test, further avoiding irregular or excessive stress on the surface of the coating sample, thereby providing more real and reliable wear data and facilitating a more accurate evaluation of the wear resistance of the coating.

A method for testing the abrasion performance of a colored anti-skid water-based coating on a road surface, using the abrasion performance testing equipment for a colored anti-skid water-based coating on a road surface as claimed in claim 8, characterized in that: The following steps are involved: Step 1: placing the coating sample to be tested into the testing groove (8), and preventing the coating sample to be tested from being excessively tilted by the testing groove (8); Step 2: After the coated sample is placed inside the test tank (8), the electric push rod (10) drives the fastening plate (11) to move in a direction away from the U-shaped frame (9). After the coated sample is fixed by the fastening plate (11), the displacement device (5) is started to operate, and the displacement device (5) drives the T-shaped frame (6) to move downward; Step 3: The T-shaped frame (6) moves downward to drive the wear test device (7) to move downward, and the wear test device (7) moves downward to contact the coating sample and operate synchronously, and the wear test device (7) operates synchronously to perform a wear resistance test on the coating sample; Step 4: After the wear test is completed, measure the weight difference of the coating sample before and after wear by weighing or use an altimeter to measure the wear depth or roughness change of the coating surface.
