  • [专利] Method for preparing chlorinated polyvinyl chloride resin
    (KR101654147) The present invention relates to a manufacturing method of a chlorinated polyvinyl chloride resin. More particularly, the manufacturing method of a chlorinated polyvinyl chloride resin efficiently removes hydrochloric acid remaining in pores of a chlorinated polyvinyl chloride resin obtained by chlorination process of PVC or PVC-containing copolymer by using a mixture of a percarbonate-based compound, or a carbonate-based compound, and hydrogen peroxide as a counteractive agent. Also, the manufacturing method of a chlorinated polyvinyl chloride resin improves thermal stability, and alleviates color differences in the resin, and color differences during a process.
  • [专利] Antistatic polyvinyl chloride resin composition and the manufacturing method of polyvinyl chloride product using the same
    (KR20160120986) The present invention relates to an antistatic polyvinyl chloride resin composition which includes 100 parts by weight of polyvinyl chloride (PVC); 1 to 50 parts by weight of at least one thermoplastic elastomer selected from the group consisting of acrylonitrile butadiene rubber, styrene butadiene rubber, isoprene rubber, styrene ethylene butylene styrene rubber and styrene butadiene styrene rubber, and a mixture thereof; and 1 to 60 parts by weight of an electrically conductive surfactant. The transparency of various products manufactured using polyvinyl chloride can be ensured and various colors are applied to the products, and an antistatic function can be constantly maintained even by in long-term use. Due to the high absorbency of the thermoplastic elastomer, the electrically conductive surfactant cannot be easily entirely activated, but activated only in a predetermined condition, so the quality of the product can be improved, which exhibits an excellent effect.

  • [专利] High flame retardant polyvinyl chloride resin composition and the manufacturing method of polyvinyl chloride product using the same
    (KR20160120978) According to the present invention, a highly flame retardant polyvinyl chloride resin composition comprises: 100 parts by weight of polyvinyl chloride (PVC); 1 to 25 parts by weight of antimony trioxide; 1 to 25 parts by weight of zinc borate; 5 to 100 parts by weight of aluminum hydroxide; 0.1 to 5 parts by weight of polytetrafluoroethylene (PTFE); and 0.1 to 10 parts by weight of a processing material in which nitrile and acrylate are comprised in a weight ratio of 1: 1 to 1:10, thereby having an advantage of minimizing deformation of a structure of the polyvinyl chloride product manufactured by using the resin composition as the composition minimizes the contact of the polyvinyl chloride product to be burned with oxygen required during a combustion reaction. Moreover, a highly flame retardant polyvinyl chloride resin composition according to the present invention has an excellent effect of minimizing any damages to humans and properties caused by fire as the composition minimizes the combustion reaction through a chain process. In addition, a highly flame retardant polyvinyl chloride resin composition according to the present invention has an advantage of excellent processibility. COPYRIGHT KIPO 2016
