Description

A coating scrub resistance testing device

Technical Field

The utility model relates to the technical field of a coating scrub resistance testing device, in particular to a coating scrub resistance performance testing device.

Background Art

The scrub resistance of paint has a great influence on the applicable places and service life of the paint, so it is also an important performance indicator of the paint. The test device for the scrub resistance of the paint is generally a test slot set on a workbench, and a coating plate is placed in the test slot. The paint sample is evenly coated on the coating plate and completely cured into a film, and then a special brush is dipped in water (washing powder or detergent can also be added to the water as needed) and moved back and forth on the coating plate. Within a certain period of time, the wear of the paint film is detected to determine the scrub resistance of the paint. Therefore, the use of paint scrub resistance test devices is becoming more and more widespread.

After searching, it was found that the publication number is CN210005378U, and the name is a water-based nano-coating scrub resistance test device. The application proposes a water-based nano-coating scrub resistance test device currently on the market. The soapy water of the water-based nano-coating scrub resistance test device is directly discharged into the sewer through the drain pipe after the test. On the one hand, it causes a waste of soapy water and water resources, which is not conducive to environmental protection. On the other hand, the test device is not automated enough and cannot meet the needs of users. By setting a circulation pipe, a collection tank and a through hole, the brush moves back and forth on the paint plate. The brush makes the soapy water on the paint plate flow into the collecting tank. The inner wall of the collecting tank is provided with a plurality of through holes. The soapy water in the collecting tank flows into the water storage chamber along the through holes. The soapy water in the water storage chamber flows into the water tank along the circulation pipe again under the action of gravity, thus realizing the recycling of the soapy water, which is beneficial to saving water resources, and is more environmentally friendly and efficient, and solves the problem that the traditional water-based nano-coating scrub resistance test device wastes water resources and is not conducive to environmental protection. At the same time, by arranging a water delivery hose, a dispersion mechanism and a brush, the soapy water flowing into the dispersion mechanism from the water delivery hose will be directly thrown to the dispersion mechanism On the left and right inner walls of the dispersion mechanism, during the inner wall and the rapid movement, the soapy water will be spread on the inner wall of the dispersion mechanism and dispersed into the capillaries. During the movement, the soapy water will quickly drive the soapy water to flow in the capillaries, so that the soapy water is sprinkled on the paint plate faster and more evenly, so that each part can be in contact with the soapy water in time during the movement of the brush, and then the brush is used to wash the paint plate with soapy water. The whole process has achieved an improved degree of automation and reduced the trouble of unnecessary manual operation, so that the test of the scrub resistance of the paint is more accurate, and the problem of insufficient automation of the traditional water-based nano-paint scrub resistance test device is solved. However, when the application is used, the brush is installed by fixing bolts, and the scrubbing force cannot be adjusted quickly and effectively. It is difficult to determine the size of the scrub resistance of the paint under different scrubbing force adjustments. The test is not comprehensive and the adjustment is more troublesome. At the same time, the brush is subject to greater wear and tear and needs to be replaced frequently. The brush of the application is fixed by fixing bolts, and frequent disassembly of the fixing bolts is very troublesome, which affects the convenience of use, and further improvements can be made.

Currently, no effective solution has been proposed for the problems in the related technologies.
