Test case
The test examples test the sealing pastes of examples 1-4 and comparative examples 1-2, wherein the water blocking test and the tensile adhesion test are performed according to JC/T2428-2017 standard, the low temperature flexibility and the heat resistance are tested according to JC/T408-2005 standard, the creep test is performed according to GB/T10120-2013 standard, and the test sample for the creep test needs to be placed in a 130-DEG oven for 3 hours in advance. The test results are shown in the following table:
TABLE 1
As can be seen from table 1, examples 1 and 2 all meet the requirements in each detection index, and show good high-potential property, and in the potential property experiment, no obvious stress relaxation phenomenon exists in a specified time, which indicates that the material itself has the capability of solving the technical problems of damage caused by stress relaxation, separation from a base surface and the like, and can continuously have good waterproof effect under deformation and external force. Example 2 is more excellent in low temperature than example 1 because more styrene-butadiene rubber and thermoplastic elastomer are added, so that the whole system exhibits better low temperature resistance. Examples 3 and 4 reduced the amount of elastomer used and a slight stress relaxation occurred. In comparative examples 1 and 2, since the elastic body was not introduced, the elastic body had a certain rigidity, and thus stress failure occurred, and a clear difference was observed in the low temperature flexibility and the tensile adhesion. Although examples 1-4 are satisfactory, there are differences in performance.
The foregoing description of embodiments of the invention has been presented for purposes of illustration and description, and is not intended to be exhaustive or limited to the embodiments disclosed. Many modifications and variations will be apparent to those of ordinary skill in the art without departing from the scope and spirit of the various embodiments described.
