Description

Technical Field

[0002] Waterproof coating is a one-component water-based waterproof coating made with pure acrylic polymer emulsion as the base material and other additives added. The waterproof film formed after curing has certain elongation, elasticity, crack resistance, impermeability and weather resistance, and can play a role in waterproofing, anti-seepage and protection.

[0003] At present, the prepared waterproof coating needs to be tested for waterproof performance before it can be put on the market. When conducting waterproof testing, it is generally necessary to first apply the waterproof coating to be tested on the fabric sample, then place the sample on the test bench, and then add water to the sample and apply a certain pressure. Observe the humidity changes of the humidity detection device under the sample under a certain pressure to determine whether the sample is leaking. However, in actual testing, due to the fixation of the clamp that fixes the sample, the tension of the fabric cannot be adjusted, which can easily cause the coating on the surface of the fabric sample to crack and affect the test results. At the same time, after the test, if there is water seepage, it is necessary to wait for the humidity detection device to dry and recover before the next test can be carried out, which is not conducive to the overall efficiency of the test operation and needs to be improved.

[0012] The beneficial effect of the utility model is as follows: during the test, the fabric sample is first clamped and fixed, specifically: first, one end of the sample is placed on the first bearing plate of the fixed fixture, and then the first hydraulic cylinder is operated to extend its piston rod, which can drive the first pressure plate to move downward until one end of the sample is pressed against the first bearing plate. Then, the second hydraulic cylinder is operated to extend its piston rod, which drives the movable plate to move toward the fixed fixture until the distance between the second bearing plate and the first bearing plate is less than the length of the sample.
