MODIFIED SULFUR BINDER WHICH IS POSSIBLE MIXING WORKABILITY BECAUSE OF MAINTAINED A LIQUID FORM FROM NORMAL TEMPERATURE AND THE FABRICATION METHOD THEREOF, HYDRAULIC MODIFIED SULFUR MATERIALS COMPOSITION AND THE FABRICATION METHOD THEREOF CONTAINING THE MODIFIED SULFUR BINDER

摘要

PURPOSE: A modified sulfur binder is provided to maintain liquid phase at room temperature, using only dicyclopentadiene as a modifier, and to conduct mixing process at room temperature. CONSTITUTION: A modified sulfur binder comprises 100.0 parts by weight of sulfur, 90-8000 parts by weight of a dicyclopentadiene based modifier containing an oligomer of trimer of cyclopentadiene. The sulfur is polymerized together with the dicyclopentadiene based modifier. The dicyclopentadiene based modifier comprises 78 weight% or less of dicyclopentadiene. The content of the dicyclopentadiene based modifier is 150-400 parts by weight. The dicyclopentadiene based modifier has viscosity of 1-100,000 mPas at 25 C.
