Embodiment 1

[0051] refer to figure 1 and figure 2 , this embodiment discloses a method for testing the adhesion performance of a self-adhesive waterproof membrane in a low temperature environment, including:

[0052] S1: Cut and make waterproof membrane sample 1, the waterproof membrane is self-adhesive waterproof membrane;

[0053] S2: Bond the waterproof membrane sample 1 with the first test connection block 2 at room temperature (25±2°C) to form a first connection body;

[0054] The self-adhesive waterproof membrane is more securely bonded at room temperature, so that one end of the waterproof membrane sample 1 is firmly connected to the first test connection block 2, and the waterproof membrane sample 1 is kept away from the first test connection block 2 One end of the terminal is used as the test terminal, which is convenient for testing;

[0055] S3: Place the first connecting body and the adhesion testing equipment 4 in the low temperature test chamber 3 for a preset time t 1 ...

Embodiment 2

[0066] refer to image 3 as well as Figure 4 , based on Example 1, this example discloses another method for testing the adhesion performance of self-adhesive waterproof rolls in a low-temperature environment. The difference between this example and the above-mentioned Example 1 is that:

[0067] This test method also uses an automatic timing device (not shown in the figure), which includes an electronic timer body (not shown in the figure), a timing start trigger switch 7, and a timing stop sensor 8, holding the adhesiveness measuring instrument Including the base 401, the base 401 is provided with a suspension hook 9, the suspension hook 9 includes a fixed end 901 and a suspension end 902, the fixed end 901 is fixed to the base 401, and the suspension end 902 is used to hang the second connecting body to be tested, The timing start trigger switch 7 is arranged under the fixed end 901 and is in contact with the lower surface of the fixed end 901. Before the second connectin...

Embodiment 3

[0071] refer to Figure 5 , based on Example 1, this example discloses another method for testing the bonding performance of self-adhesive waterproof rolls in a low-temperature environment. The differences between this example and Example 1 are:

[0072] At least one test mark line 501 is set on the second test connection block, and the test mark line 501 is located in the bonding range between the waterproof membrane sample and the second test connection block.

[0073] After the second connecting body is suspended, the lower end face of the second test connection block is the first end face, and the upper end face is the second end face.

[0074] In this embodiment, the distance from the test mark line 501 to the first end surface is H, and the value of H is 0

[0075] The value of H can be 40mm, 35mm, 30mm, 25mm, 20mm, 15mm, 10mm, 5mm.

[0076] In this embodiment, the mode of testing the bonding performance of the waterproof coiled material is:

Abstract

The invention discloses a bonding performance testing method for a self-bonding waterproof roll in a low temperature environment. The scheme comprises the steps: S1, a waterproof roll sample is cut and made; S2, the waterproof roll sample is bonded with a first test connecting block at room temperature to form a first connecting body; S3, the first connecting body and bonding force testing equipment are placed in a low temperature test chamber to be stored for a preset time t1, and a preset temperature value T is preset for the low temperature test chamber; S4, in the low temperature test chamber, the end, far away from the first test connecting block, of the waterproof roll sample is folded by 180 degrees and then bonded with a second test connecting block to form a second connecting body; and S5, in the low temperature test chamber, after the second connecting body is stored for a preset time t2, the bonding performance of the second connecting body is tested on the bonding force testing performance. According to the testing method, the condition of bonding the waterproof roll in the low temperature environment can be simulated, the bonding strength that the waterproof roll can achieve in the low temperature environment is tested, and it is beneficial to acquire the waterproof roll bonding performance data approaching to the actual construction process.

Description

technical field [0001] The invention relates to the field of performance testing of waterproof coiled materials, in particular to a method for testing the adhesion performance of self-adhesive waterproof coiled materials in a low-temperature environment. Background technique [0002] At present, the waterproof performance of buildings is an important index to evaluate the construction quality, and the performance of waterproof materials and waterproof construction technology play a decisive role. [0003] At present, the large-area waterproof construction technology is to first lay waterproof membranes on the foundation surface, and then cover the surface of the waterproof membranes with concrete. [0004] If the bonding force between the waterproof membrane and the base surface is not good, it will lead to problems such as water channeling and water leakage. Therefore, the bonding performance of the waterproof membrane will have a great impact on the waterproof effect. [...
