The first type of the method is complex in operation method, requires a lot of experimental tools and is disordered, and the second type of the method is not very accurate in experimental result and is not strong in intuition for customers.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide a test method for the waterproof effect of the waterproof coating, which has more reasonable structural design.
In order to achieve the purpose, the invention adopts the technical scheme that: a test method for waterproof effect of waterproof paint is characterized by comprising the following steps:

(2) pretreatment of test substrates: blowing impurities adhered to the inner surface of the container completely by adopting a high-pressure gas blowing mode, and then completely wrapping the outer surface of the container by using a film;
(3) preparation of test waterproof coating: the waterproof coating to be tested is prepared in proportion, and then the waterproof coating is coated on the inner surface of the container except for the sealing ring for multiple times according to the corresponding construction process, so that the integrity of the coating film is ensured, and the coating thickness is controlled to be 1.4-1.7 mm;
(4) curing and drying thoroughly: placing the test substrate coated with the test waterproof coating into a hot air box, controlling the temperature of hot air in the hot air box to be 30-40 ℃, starting a moisture exhaust fan of the hot air box, periodically dehumidifying the hot air box until the coating is completely dried, and tearing off a film outside the container;
(5) and (3) pressure test: the sealing cover is covered at the opening at the top of the container and is fixed on the container in a buckling mode, meanwhile, pressure is applied to the sealing cover, the sealing cover is prevented from being flushed away due to increase of air pressure, then pressurized air is filled into the container through the pressure pump, when the pressure gauge displays testing pressure, pressurization is stopped, pressure is maintained in the container for 30min, and then whether water leakage exists outside the container or not is checked.
Further, the mesh size of the container is 0.2-0.5 cm.
Further, the test waterproof coating is preferably a composite waterproof coating.
Compared with the prior art, the invention has the following beneficial effects:
by adopting the method, the operation process is relatively simple, the used test materials are relatively less, and the test result is relatively accurate and more visual.
Detailed Description
