THERMOMECHANICAL PROPERTIES OF PHOSPHATE ADHESIVES BASED ON SPENT ACTIVATED ALUMINUM OXIDES
Abstract
The conducted studies have shown that the most important thermomechanical and thermophysical characteristics of fire-resistant phosphate adhesives depend to a large extent on the type of phosphate binder. [1] Compositions on H3PO4 due to the presence of a large amount of glass phase have reduced fire resistance, deformation temperature under load and heat resistance, for adhesives on AXFC these indicators are significantly higher [2]. In addition, they have a comparatively lower coefficient of linear thermal expansion and open porosity, as well as better adhesive properties.
