Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of adhesion testing, in particular to a device and method for testing the adhesion of colored polymeric coatings on road surfaces. BACKGROUND

[0002] Colored polymeric coatings on road surfaces are designed for roads, parking lots and sidewalks, etc. They not only give the surface a beautiful color, but also enhance the friction of the road surface, improve traffic safety, and have excellent wear resistance, water resistance and slip resistance. Given the frequent impact of vehicle driving and pedestrian stepping on road surfaces, in order to ensure that the coatings have excellent wear resistance and prolong their service life, and to verify their performance and durability in actual application, adhesion tests are usually required after the coatings dry.

[0003] The commonly used adhesion testing method is to use a bond strength detector (also known as an adhesion tester). During testing, the pulling head (i.e., spindle) is first fixed to the surface of the coating by high-strength glue (such as epoxy resin or AB glue), and pressure is applied to remove air bubbles. After the glue is completely cured, a hydraulic device is used to apply tension to the spindle until the coating is peeled off from the substrate. The maximum tension value recorded during this process is used to evaluate the adhesion of the coating.

[0004] However, the existing adhesion tester is equipped with a limited number of spindles, while in actual operation, it is often necessary to test a larger area or multiple areas.

[0038] like Figures 1 to 10 As shown, the complete method of using a colored polymer coating adhesion testing device for road surfaces according to the present invention includes the following steps: Step 1: First, apply high-strength adhesive to the bottom of spindle 14. Then, align the bottom of spindle 14 with the colored polymer coating to be tested on the road surface. Wipe away any excess adhesive exposed on the road surface with a wiping cloth. Wait for a period of time for the adhesive to cool and solidify. Then, use an external scraper to completely cut off the adhesive and coating around spindle 14 to avoid affecting the test results. Next, put the lower end of the hydraulic pull tube 2 onto spindle 14. Then, turn on the main power of the tester body 1 and set the relevant data on the tester body 1. Wait for the hydraulic pull tube 2 to work automatically and pull spindle 14 upward until spindle 14 and the coating fall off the road surface together. Test according to the data recorded on the tester body 1 to obtain the adhesion performance of the coating. Step two: after the spindle 14 is pulled out together with the paint, in order to continue to reuse the spindle 14, just align the spindle 14 with the vertical push plate 38 which just blocks the entrance 10, and press a little harder, so that the second pressure sensor 44 inside the vertical push plate 38 senses the pressing signal, at this time the second pressure sensor 44 transmits the electrical signal to the processor inside the tester body 1, and then the second multi-stage hydraulic rod 31 is started through the controller inside the tester body 1; Step three: after the second multi-stage hydraulic rod 31 is started, its output end starts to recover, and in the process of recovery, the vertical push plate 38 and the spindle 14 on the vertical push plate 38 descend into the soaking box 4, and then when the surface of the vertical push plate 38 is flush with the partition plate 32, the vertical push plate 38 will abut against the second self-resetting switch 43 on the second sealing plate 37, the second self-resetting switch 43 is forced to start, and then the first multi-stage hydraulic rod 19 can be opened through the controller inside the tester body 1; Step four: after the first multi-stage hydraulic rod 19 is started, its output end will push the horizontal push plate 21 to move forward, at this time the horizontal push plate 21 will push the spindle 14 on the vertical push plate 38 forward, until the spindle 14 is just clamped between the two slide rails 18, and then the spindle 14 continues to move under the push of the horizontal push plate 21, when the spindle 14 moves to the slope of the slide rail 18, the horizontal push plate 21 stops moving and starts to return, when the horizontal push plate 21 returns to contact the first self-resetting switch 42 on the first sealing plate 20, at this time the controller inside the tester body 1 will start the second multi-stage hydraulic rod 31 again, so as to push the vertical push plate 38 back to the original position to seal the entrance 10 of the soaking box 4; Step five: when the spindle 14 is pushed to the slope of the slide rail 18, at this time the spindle 14 will slide to the lower end of the slide rail 18 due to gravity, and when the horizontal push plate 21 touches the first self-resetting switch 42 to make the vertical push plate 38 rise to completely seal the entrance 10, the controller inside the tester body 1 will also start the moving motor 40 and the liquid supply pump 23 at the same time; Step six: after the moving motor 40 is started, its output shaft will rotate with the screw rod 30, and the screw rod 30 will rotate to move the herringbone block 39 connected to the screw rod 30 and the auxiliary slide rod 27, and at this time the spindle 14 is located at the lower end of the two slide rails 18, so when the herringbone block 39 moves along the screw rod 30 and the auxiliary slide rod 27, it can just push the spindle 14 to the L-shaped bracket 29, and then when the first pressure sensor 41 on the herringbone block 39 detects that it cannot push any further, the first pressure sensor 41 will transmit the electrical signal to the processor inside the tester body 1, and the moving motor 40 will be controlled to reverse through the controller inside the tester body 1, so as to control the herringbone block 39 to return to the original position; Step seven: when the liquid supply pump 23 starts, the input end of the liquid supply pump 23 faces downward, and the clean and softening glue cleaning liquid in the inside of the clean water box 11 is extracted, and then the liquid supply pump 23 pumps the cleaning liquid from the output end into the liquid supply pipe 24, the cleaning liquid in the pipe liquid supply pipe 24 flows out from the other end of the liquid supply pipe 24, and the liquid supply pump 23 stops automatically after working for a period of time and outputting the preset cleaning liquid capacity, and at the same time when the liquid supply pump 23 stops, the first electromagnetic valve 25 connected to the liquid supply pipe 24 starts to close the liquid supply pipe 24 to avoid backflow of the cleaning liquid, and after the cleaning liquid enters the inside of the soaking box 4, due to gravity, the cleaning liquid stays at the lower end of the soaking box 4, which can soak the lower end of the spindle 14 inside, so as to soak the glue and paint at the bottom of the spindle 14 and gradually soften them; Step eight: when the spindle 14 moves to the L-shaped support 29, the test instrument main body 1 inside the controller also starts the third multi-section hydraulic rod 17 at the same time while the moving motor 40 reverses, and after the third multi-section hydraulic rod 17 starts, the output end thereof is retracted inward and moves the L-shaped sealing plate 5 together until the L-shaped sealing plate 5 is retracted to the position between the inclined plate 15 and the soaking box 4 and then stops automatically; Step nine: at this time, the operator only needs to pull the pull ring 7, and the pull ring 7 under stress pulls the pull rope 6 upward, and the pull rope 6 upward can pull the L-shaped support 29 together upward under the cooperation of the sliding block 36 and the sliding groove 33, so as to pull the spindle 14 clamped on the L-shaped support 29 to the position of the outlet 9, and because the width of the lower end of the spindle 14 is not greater than the distance between the two slide rails 18, the spindle 14 can be pulled out directly from the outlet 9, and then the softened glue and the paint adhered to the glue are wiped off together, and after the spindle 14 is wiped clean, it can be reused, which is extremely suitable for use when the number of spindles 14 is insufficient for measuring multiple points; Step ten: after the spindle 14 is taken out from the L-shaped support 29, the pull rope 6 is loosened, and the L-shaped support 29 can return to the original position under the action of its own gravity and be flush with the two slide rails 18 again; Step eleven: if the glue at the bottom of the second, third or more spindles 14 needs to be softened and recycled, the above steps can be repeated, and if the glue at the bottom of other spindles 14 does not need to be softened again, the operator can start the third multi-section hydraulic rod 17 again through the operation screen in front of the test instrument main body 1, and after the third multi-section hydraulic rod 17 continues to start, the L-shaped sealing plate 5 is pushed outward and blocks the outlet 9; Step twelve: while the operator starts the third multi-stage hydraulic rod 17 to close the outlet 9, the second electromagnetic valve 26 connected to the sewage pipe of the sewage outlet of the sewage box 3 is started, and then the sewage cleaning liquid in the soaking box 4 flows into the sewage box 3, and then the second bolt between the sewage box 3 and the soaking box 4 and the water purification box 11 is loosened, and the sewage box 3 is taken down, then the first bolt of the shielding plate 28 at the cleaning port 34 is loosened, and the sewage in the sewage box 3 is discharged, and then the inside of the sewage box 3 and the soaking box 4 is cleaned, which is convenient, fast and easy to operate.
