Description

Technical Field

[0001] The present application relates to the technical field of waterproof coating test, and in particular to a waterproof coating test film mold frame. Background Art

[0002] The waterproof coating test film mold is a mold used to prepare waterproof coating samples. Its design and manufacture meet specific standards, such as GB / T16777. Through this film mold, a sample film of a specific size can be made, and then the film is cut with a slicer to obtain a dumbbell-shaped type I specimen that meets the requirements of GB / T528 standard for different tensile tests. When using the waterproof coating test film mold, in order to ensure smooth demoulding, silicone oil or paraffin can be used as a demoulding agent on the substrate (glass plate) and the mold frame for surface treatment. At the same time, before the test, it is necessary to ensure that the samples and the instruments used are placed under standard conditions (such as temperature 23℃±2℃; relative humidity 45%~70%) for a certain period of time. When preparing the sample, the evenly stirred waterproof coating needs to be immediately poured into the film mold for coating without mixing in bubbles.

[0003] Currently, most of the waterproof coating test film molds on the market use hexagonal or octagonal fixed 1.5mm thick plywood to press and fix the glass plate (the glass plate is coated with a coating film) to avoid displacement of the glass plate bearing the coating. In actual operation, when the test personnel use a scraper to scrape the sample, the multi-angle fixed component will contact the operator's arm or the scraping device, causing operational interference and obstacles, thereby affecting the smooth scraping operation of the coating.

[0004] Usually, the required amount of test samples is weighed under standard test conditions to ensure the final coating thickness of (1.5 ± 0.2) mm. The specimen is required to be coated once or multiple times during the preparation stage (up to three times, with an interval of no more than 24 hours between each coating). Due to the influence of scraping interference from fixed components, it is difficult to ensure that the coating thickness is very uniform and that the coating is smooth according to the number of times, resulting in low test efficiency. Summary of the invention

[0005] In response to the above-mentioned problems, the present application aims to provide a waterproof coating test coating mold frame, which can accurately control the upper surface of the film thickness reference body during coating and scraping, thereby improving the accuracy of the film thickness, and at the same time solving the problem of the need to fix the glass plate by multi-angle fixing components, which affects the scraping operation, thereby ensuring the scraping effect and quality of the film layer.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in the present application is as follows: a waterproof coating test coating mold frame, the coating mold frame is internally provided with a supporting platform for carrying a rubber pad and a glass plate, characterized in that: a plurality of film thickness reference bodies with the same coating thickness as the coating film are also arranged on the glass plate, and a limiting component connected to the film thickness reference body and driving the film thickness reference body and the glass plate to be relatively positioned is also arranged in the coating mold frame.

[0007] Preferably, each of the film thickness reference bodies has the same thickness as the currently coated film and is flatly attached to the side of the glass plate, or are film thickness reference plates that are flatly attached to each other.

[0008] Preferably, the limiting member is a limiting block extending in an L-shape on the outer side of the film thickness reference plate, and a limiting groove for embedding the limiting block is provided on the coating mold frame on the outer side of the base.

[0009] Preferably, traction members connected to the limiting block and pulling the limiting block are evenly spaced in the limiting groove.

[0010] The beneficial effect of the present application is that the coating mold frame is provided with multiple layers of film thickness reference bodies with the same coating thickness as the coating film on the glass plate, and each layer of the film thickness reference bodies has the same coating thickness as the current layer, that is, after the film thickness reference body is placed flat on the side of the glass plate surface, the coating and leveling of the paint can be carried out with the upper surface of the film thickness reference body as the precision, and the leveling and film thickness can be controlled, thereby improving the accuracy of the film thickness and facilitating the leveling operation.

[0011] The limiting component drives the film thickness reference body to be relatively fixed to the glass plate and realizes the fixation of the glass plate, thereby solving the problem that the glass plate needs to be fixed by a multi-angle fixing component, which affects the scraping operation, thereby ensuring the scraping effect and quality of the film layer.

[0018] In order to enable ordinary technicians in the field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0019] Refer to the attached Figures 1 to 5 A waterproof coating test film mold frame is shown, and a base 11 for carrying a rubber pad 2 and a glass plate 3 is arranged inside the coating mold frame 1. During operation, the rubber pad 2 and the glass plate 3 are placed on the base 11 in sequence. Preferably, the rubber pad 2 is also arranged at the upper side edge of the glass plate 3, and the glass plate 3 is pressed and fixed by a fixing member with a polygonal structure, and then the coating can be applied on the glass plate 3. The rubber pad 2 is used to achieve a buffering effect on the upper and lower sides of the glass plate 3 to prevent the glass plate 3 from being broken due to hard contact.

[0020] In order to solve the problem that the fixed components of the current polygonal structure affect the scraping operation of the paint, such as Figure 3-5 As shown, a plurality of film thickness reference bodies having the same coating thickness as the coating film are also arranged on the glass plate 3, and each layer of the film thickness reference body has the same coating thickness as the current layer. For example, if the coating thickness is 0.75 mm, the thickness of the current film thickness reference body is also 0.75 mm. That is, after the film thickness reference body is placed flat on the side of the surface of the glass plate 3, the coating and leveling of the paint can be carried out with the upper surface of the film thickness reference body being accurate, and the leveling and film thickness control can be performed, thereby improving the accuracy of the film thickness and facilitating the leveling operation.

[0021] When performing multiple coating operations, a film thickness reference body with the same thickness as the second layer of coating is placed flat on the current film thickness reference body again, and the coating and scraping operations are performed again. In this way, the coating operation can be completed.

[0022] In order to fix the glass plate 3 and the film thickness reference body, Figure 4-5 As shown, a limiting member connected to the film thickness reference body and driving the film thickness reference body to be relatively positioned with the glass plate 3 is also provided in the coating mold frame 1. The limiting member drives the film thickness reference body to be relatively fixed with the glass plate 3 and realizes the fixation of the glass plate 3, thereby solving the problem that the glass plate 3 needs to be fixed by a multi-angle fixing member at present, which affects the scraping operation, thereby ensuring the scraping effect and quality of the film layer.

[0023] Specifically, Figure 3-5As shown, each of the film thickness reference bodies is a film thickness reference plate 4 having the same thickness as the currently coated film and flatly attached to the side of the glass plate 3, or flatly attached to each other. The film thickness reference plate 4 of the first film layer is attached to the surface of the glass plate 3, and the second and subsequent film thickness reference plates 4 are attached in sequence. Each film thickness reference plate 4 realizes a reference reference for the current film layer coating, thereby improving the dimensional accuracy of each film layer.

[0024] Specifically, Figure 3-5 As shown, the limiting member is a limiting block 41 extending in an L shape on the outer side of the film thickness reference plate 4, and a limiting groove 1a for embedding the limiting block 41 is provided on the coating mold frame 1 outside the support 11. Figure 4 In the assembly process shown, the rubber pad 2 and the glass plate 3 are first placed on the support 11 in sequence, and then the film thickness reference plate 4 is flatly attached to the side of the glass plate 3, and the limit block 41 is embedded in the limit groove 1a, and the bottom surface of the limit block 41 is attached to the bottom surface of the limit groove 1a, that is, the film thickness reference plate 4 is pressed against the side of the glass plate 3 by the limit block 41, and then the first layer of paint is applied on the glass plate 3. Figure 4 As shown in the lowermost figure, the second film thickness reference plate 4 is flatly attached to the first film thickness reference plate 4, and the limit block 41 of the second film thickness reference plate 4 is embedded in the limit groove 1a, and the bottom surface of the limit block 41 is attached to the bottom surface of the limit groove 1a, and then the second layer of coating is applied on the glass plate 3.

[0025] To further press and fix the glass plate 3, Figure 1-2 As shown in Figures 5 and 6, traction members 5 are evenly spaced in the limiting groove 1a and are connected to and pull the limiting block 41. The traction member 5 is preferably a strong magnetic block fixedly embedded in the limiting groove 1a, and the strong magnetic block can suck the limiting block 41 into the limiting groove 1a, and then the glass plate 3 can be pressed against the support 11 through the film thickness reference plate 4, thereby improving the tightness of the glass plate 3 assembly.

[0026] To facilitate the loading and unloading of the film thickness reference plate 4, Figure 1 As shown, a strong magnetic switch connected to the strong magnetic block is also provided at the side of the coating mold frame 1, which can control the adsorption strength of the strong magnetic block to the limit block 41, thereby facilitating the loading and unloading of the film thickness reference plate 4.

[0027] The principle of the present application is: when conducting a waterproof coating test, first place the rubber pad 2 and the glass plate 3 on the support 11 in sequence, then place the film thickness reference plate 4 flat on the side of the glass plate 3, and make the limit block 41 embedded in the limit groove 1a, and at the same time, the bottom surface of the limit block 41 is in contact with the strong magnetic block in the limit groove 1a, and the strong magnetic switch controls the strong magnetic block to adsorb the limit block 41, and make the film thickness reference plate 4 pressed against the side of the glass plate 3. Then apply the first layer of coating on the glass plate 3. Figure 4 As shown in the bottom figure, the second film thickness reference plate 4 is flatly attached to the first film thickness reference plate 4, and the stopper 41 of the second film thickness reference plate 4 is embedded in the stopper groove 1a, and the bottom surface of the stopper 41 is attached to the bottom surface of the stopper groove 1a, and then the second layer of coating is applied on the glass plate 3. Each film thickness reference plate 4 realizes the reference reference for the current film layer coating, thereby improving the dimensional accuracy of each film layer, and solving the problem of affecting the leveling operation when the glass plate 3 needs to be fixed by a multi-angle fixing member, thereby ensuring the leveling effect and quality of the film layer.

[0028] The above shows and describes the basic principles, main features and advantages of the present application. Without departing from the spirit and scope of the present application, the present application may have various changes and improvements, which fall within the scope of the present application to be protected.
