Effect of SBS/HVS Blend on Modification of Physical and Chemical Properties of Bituminous Emulsion Insulators

Bituminous emulsion insulators are types of bituminous emulsions groups composedof different grades of bitumen emulsified in water by bentonite andemulsifiers at 80-90oC. These emulsions are water resistant after drying andtheir physical and mechanical properties are superior in comparison to bitumen properties.Iranian climate, because of variety and extreme variations in temperature imposeshigh performance insulators. Modification of bitumen is considered as one of the mostpractical applications of polymers to impart more improved properties to bitumen. Thisinvestigation involved the study of polymers and resins such as SBS and heavy vacuumslops (HVS). For this purpose, the effect of each component of emulsions on the physicaland chemical properties of insulators was examined and some insulators are madewith more improved properties.
