Description

TECHNICAL FIELD

[0001] The utility model relates to a paint film test technical field, concretely relates to a water -based paint paint film adhesion performance testing machine. BACKGROUND

[0002] Water -based paint is harmless to human body, does not pollute the environment, and has the characteristics of full paint film, crystal clear, good flexibility and water resistance, wear resistance, aging resistance, yellowing resistance, fast drying and convenient use. During the production of water -based paint, samples need to be produced for coating. The paint film after coating is tested for various properties by performance testing equipment. Among them, the adhesion strength test of the paint film is an essential part.

[0003] A water -based paint paint film adhesion performance testing machine is disclosed in Chinese patent No. CN211318155U, which includes a heating base. The upper surface of the heating base is equipped with replaceable extrusion devices. The upper surface of the heating base is provided with a groove. The groove is equipped with a removable test plate. The front surface of the heating base is provided with a storage groove. The limit block is rotatably assembled in the rotating groove. The rear surface of the limit block is attached to the front surface of the test plate. When the test plate is inserted into the groove, the upper surface of the test plate is at the same level as the upper surface of the heating base. When in use, the test plate is inserted into the groove, and then the limit block is rotated to make its rear surface attached to the front surface of the test plate. The heating base is started to heat the test plate. Then, the anti -skid sleeve is held with both hands to roll the front end of the connecting rod and the extrusion shaft. The extrusion shaft uniformly extrudes and adheres the paint film on the upper surface of the test plate. After extrusion, the heating base is turned off, and the test plate is taken out from the groove and observed under the microscope.

[0004] However, the above technical solution has the following disadvantages: the water -based paint is extruded onto the test plate by the extrusion shaft. The thickness of the paint film coated by the device is fixed. Thus, only single -thickness test can be performed during the experiment, resulting in single experimental data during the paint film adhesion strength test, affecting the accuracy and diversity of the experimental data, and the judgment error is large. Moreover, it cannot be more consistent with the actual use. UTILITY MODEL CONTENTS
