POLYMER COMPOSITION USING WASTE EDIBLE OIL FOR AGGREGATE BINDER

摘要

PURPOSE: Provided is a polymer composition using a waste edible oil for an aggregate binder, which has improved heat resistance, low-temperature elasticity and performance as a paving material compared with a conventional asphalt binder, and shows various colors. CONSTITUTION: The polymer composition using waste edible oil for an aggregate binder comprises 3-40 wt% of a styrene-conjugated diene block copolymer, 0.5-70 wt% of an adhesion-imparting agent and 0.5-60 wt% of waste edible oil. In particular, the styrene-conjugated diene block copolymer is selected from the group consisting of a styrene-butadiene-styrene block copolymer, a styrene-isoprene-styrene block copolymer, a styrene-ethylene-butadiene-styrene block copolymer and a styrene-butadiene block copolymer and a mixture thereof.
