Abstract

Abstract:

In order to clarify the chemical composition and the effect of filler addition on the physical properties of the space silicone rubber, the filler compound method was used to prepare the silicone rubber polymer material. The chemical composition test, atomic oxygen exposure test, and mechanical property test were used to study its structural composition and physical properties. The particle size of the silica filler was mainly distributed between 8 and 16 μm by the micro-particle size test. After Fourier transform infrared spectrophotometry(FTIR), nuclear magnetic resonance( ¹H NMR and ²⁹Si NMR) and gel permeation chromatography(GPC) tests, it was found that the silicone rubber contained various groups, such as Si—Me, Si—Ph and Si—O—Si and its molecular weight dispersion coefficient was 1.56. It was further deduced that the reaction type of the base rubber and the cross-linking agent was dehydroxyamine type. Atomic oxygen exposure tests and mechanical tests confirmed that silane-modified silicone rubber polymer material exhibited better antigenic oxygen performance, 54% higher storage modulus after dynamic mechanical tests, and better mechanical response performance. The results show that the surface modification treatment can enhance the interaction between the filler and the silicone rubber, and improve the antigenic oxygen performance and comprehensive mechanical properties of the filler composite silicone rubber polymer material.
