Title:
MODIFIED SULFUR, METHOD FOR PREPARING SAME, APPARATUS FOR PREPARING SAME, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2013/191500
Kind Code:
A1
Abstract:
The present application relates to modified sulfur, to a method for preparing same, and to an apparatus for preparing same. The modified sulfur is radioactive or includes a fine structure such as a fibrous structure, a tabular structure, or a network structure. The modified sulfur may be prepared by a process of inducing polymerization or aging using ultrasonic waves. The modified sulfur may have various excellent characteristics such as anticorrosion, water resistance, strength, and high-speed drying, and such characteristics may be adjusted based on the viscosity or the degree of polymerization. Further, as the modified sulfur has the above-described characteristics, the modified sulfur can be applied to an anticorrosive material or water-resistant material, and the modified sulfur can be used in the production of an anticorrosive material and water-resistant material having superior workability and hardening properties, resistance to salt spray, weldability, and the like at an optimum level, and particularly having improved adhesion. Further, when the modified sulfur is applied to an asphalt composition, gelation and depression can be reduced, physical properties such as flexural strength and tensile strength can be improved, and excellent work stability at normal temperatures can be ensured.
