Quantitative analysis method and its impact factor of high temperature vulcanized silicone rubber applied in outdoor insulation

Silicone rubber have been applied as an excellent composite materials in outdoor insulation and play an important role in protecting the core and providing hydrophobicity. In the long-term field operation, it is suffered to the combined effect of natural environment, pollution accumulation and electric field, and thus there will be typical ageing phenomena such as housing erosion, shed tearing and hydrophobicity loss, which were closely related to the recipe of silicone rubber. Silicone rubber is mainly composed of PDMS (polydimethylsiloxane), ATH (Alumina trihydrate), SiO
2
(silicon dioxide) three substances, and the proportion of each component is very important for the overall performance of silicone rubber. Thus it is crucial to quantitatively analyse the components and contents of high temperature vulcanized silicone rubber applied in outdoor insulation, and explain the effect of the impact factors.
