Abstract

The principles of creating frost-resistant sealing materials are considered. The influence of components (fillers, plasticizers and crosslinking agents) on the frost resistance of sealants was investigated. Two methods for evaluating the frost resistance of sealants have been studied: the determination of the strength and elongation of the material at a negative temperature, the determination of the dynamic shear modulus G and the tangent of the mechanical loss angle tgδ in the negative temperature region. The article presents data on glass transition temperatures of sealing materials, as well as temperature dependences of the dynamic mechanical characteristics of sealants, depending on their polymer base. It is shown that the frost resistance of sealants is an ambiguous concept, since the operability of the material in a structure depends not only on its properties, but also on the characteristics of hermetic joints and the conditions of their operation.
