    • 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.
    • 目的:提供半刚性路面的灌浆组合物,具有高流动性,高耐久性和提高的填充能力,包括在精炼过程中产生的硫单体的硫聚合物乳液。 构成:基于100重量份的粘结材料成分,用于半刚性路面的灌浆组合物包含10-30重量份的树脂组分和15-35重量份的混合溶液。 树脂组分包含10-45wt%的硫聚合物乳液和55-90wt%的丙烯酸共聚物。 硫聚合物浸出物由在精炼进料中产生的硫单体聚合。 丙烯酸共聚物的粘度为330-400cps,密度为0.98-1.0g / cm 3。 硫聚合物乳液的制造方法包括以下步骤:通过在炼油厂中产生的硫单体中加入第一改性剂来进行初级液相聚合; 通过向主要聚合的硫单体聚合物添加第二改性剂进行二次液相聚合; 并加入表面活性剂进行乳液聚合。 第一改性剂选自环戊二烯基团,第二改性剂选自烯烃基烃。
