Test example
This test example tests the sealing pastes of examples 1 to 4 and comparative examples 1 to 2; the method comprises the following steps of performing a water closing test and a tensile cohesiveness test according to JC/T2428-2017 standard, testing low-temperature flexibility and heat resistance according to JC/T408-2005 standard, performing a latent deformability test according to GB/T10120-2013 standard, and putting a sample of the latent deformability test 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 both meet the requirements in various detection indexes, show good high creep deformation, and have no obvious stress relaxation phenomenon within a specified time in a creep deformation experiment, 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 resulted in a slight stress relaxation phenomenon. In comparative examples 1 and 2, no elastomer is introduced, so that the rubber has certain rigidity, and the stress failure phenomenon occurs; a clear distinction can also be seen in the low temperature flexibility, stretch adhesion. Although examples 1-4 are satisfactory, there is a difference in performance.
Having described embodiments of the present invention, the foregoing description is intended to be exemplary, not exhaustive, and not 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 described embodiments.
