Background

Silicone rubber refers to rubber having a backbone composed of alternating silicon and oxygen atoms, with the silicon atoms typically having two organic groups attached to them. Conventional silicone rubbers consist predominantly of siloxane segments containing methyl groups and small amounts of vinyl groups. The introduction of phenyl can improve the high and low temperature resistance of the silicone rubber, and the introduction of trifluoropropyl and cyano can improve the temperature resistance and oil resistance of the silicone rubber. The silicon rubber has good low-temperature resistance and can still work at the temperature of minus 55 ℃. After introducing phenyl, the temperature can reach-73 ℃. The silicon rubber has outstanding heat resistance, can work for a long time at 180 ℃, can still have elasticity for a plurality of weeks or more even at the temperature slightly higher than 200 ℃, and can instantaneously resist the high temperature of more than 300 ℃. Silicone rubber has good gas permeability, and oxygen transmission rate is the highest among synthetic polymers. In the production process of the silicone rubber, the finished product of the silicone rubber needs to be sampled and detected, wherein the finished product needs to be detected for strength and elasticity so as to ensure that the silicone rubber has good performance. The common elasticity detection method generally directly uses a pressure sensor to cooperate with a pressure applying mechanism to extrude and observe the silicon rubber, but manual observation has certain error, and the existing elasticity detection testing machine usually only detects the compression elasticity of the silicon rubber, neglects the tensile elasticity of the silicon rubber, and causes that part of the residual products are not detected out to influence the quality of the silicon rubber product.
