Description

[0002] Sealant refers to a sealing material that deforms with the shape of the sealing surface, is not easy to flow, and has a certain degree of adhesion. It is an adhesive used to fill the gaps in the structure to achieve a sealing effect. It has the functions of preventing leakage, waterproofing, anti-vibration, sound insulation, and heat insulation. It is usually based on dry or non-drying viscous substances such as asphalt, natural resin or synthetic resin, natural rubber or synthetic rubber, etc., with inert fillers such as talcum powder, kaolin, carbon black, titanium dioxide and asbestos, and then added with plasticizers, solvents, curing agents, accelerators, etc.

[0003] During the high temperature resistance test of existing sealants, it is difficult to perform multiple temperature test results during constant temperature testing, and repeated tests are required. When using multiple temperature tests, it is easy to be affected by the overall temperature and reduce the test effect, making it difficult to perform accurate high temperature resistance testing on the sealant. Moreover, when performing different temperature tests, the tests of multiple test heads are easily affected by the highest temperature, causing the overall deformation of the sealant to be large, making it difficult to perform accurate testing on the sealant at a lower temperature.
