Description

Technical Field:

[0001] The utility model relates to the technical field of equipment for testing the performance of decorative coatings, and particularly relates to a film forming device for waterproof coatings. Background Art:

[0002] Waterproof coatings are an essential type of coating in building interior decoration materials. The quality and compliance of waterproof coatings directly affect the reliability of decoration; in the actual application process of waterproof coatings, it is necessary to first make a mold and then conduct performance testing experiments on it; the method and quality of making a mold for waterproof coatings directly affect the efficiency and accuracy of testing.

[0003] Currently, the method of making a mold for waterproof coatings in the industry is as follows: First, the tester pours a part of the waterproof coating in the bucket onto the non-stick glass with a border, and then the tester manually uses a scraper to perform scraping and leveling operations. The thickness of the mold is the vertical height between the non-stick glass and the top surface of the border, usually 1.5 ± 0.02 mm. After natural drying, the prepared film sample is taken out for the next step of performance testing.

[0004] Problems existing in the existing mold making method are: (1) When pouring the waterproof coating onto the non-stick glass, the amount poured by the tester is controlled by experience and cannot be well controlled, resulting in an overage phenomenon and the need to scrape off the excess, which affects the mold making efficiency; (2) The tester first pours a pile of the waterproof coating in the bucket onto the non-stick glass and then spreads and scrapes it. However, a large amount of the poured waterproof coating accumulates, and there are a large number of air bubbles inside, resulting in serious holes in the prepared film sample and causing the sample preparation to be unqualified; (3) Manual pouring and scraping are carried out, and the entire process has a large labor intensity and low efficiency. In addition, due to the different scraping and mold making techniques of each tester, the waterproof coating is unevenly stressed, resulting in errors in the mold making thickness and flatness.
