FILLING COMPOSITION FOR SEMI-RIGID PAVEMENT COMPRISING SULFUR POLYMER EMULSION

摘要

PURPOSE: A grout composition for semi-rigid pavement is provided to have high-fluidity, high endurance and improved filling ability by including sulfur polymer emulsion from sulfur monomer generated in refining progress of stock. CONSTITUTION: A grout composition for semi-rigid pavement comprises 10-30 parts by weight of resin components and 15-35 parts by weight of mixing solution based on 100 parts by weight of binding material components. The resin component comprises 10-45 wt% of sulfur polymer emulsion and 55-90 wt% of acrylic copolymer. The sulfur polymer emersion is polymerized from sulfur monomer generated in a refining progress of stock. The acrylic copolymer has the viscosity of 330-400cps and the density of 0.98-1.0g/cm^3. A manufacturing method of the sulfur polymer emulsion comprises the following steps: performing primary liquid phase polymerization by adding first modifier to the sulfur monomer generated in an oil refinery; performing secondary liquid phase polymerization by adding second modifier to the sulfur monomer polymer which is primarily polymerized; and adding surfactant to perform emulsion polymerization. The first modifier is selected from a cyclopentadiene group and the second modifier is selected from olefin based hydrocarbon.
