Title:
WATERSTOP-INSULATION RING AND INSULATING VALVE CHAMBER USING SAME
Document Type and Number:
WIPO Patent Application WO/2023/042930
Kind Code:
A1
Abstract:
The present invention relates to an insulation member for preventing conduction between objects and, more specifically, to: a waterstop-insulation ring for providing insulation between a valve chamber buried underground and a pipeline provided to pass through the valve chamber; and an insulation valve chamber capable of preventing corrosion of the pipeline by using same. The waterstop-insulation ring according to the present invention is technically characterized by being a ring-shaped insulation member having a right trapezoidal cross-section, and by being formed from a material obtained by cross-linking and mixing, on the basis of 100 parts by weight of a carbon-containing rubber (carbon master batch), 0.5-0.7 parts by weight of zinc dibutyldithiocarbamate, 0.3-0.5 parts by weight of N-cyclohexyl-2-benzothiazole sulfonamide, 0.2-0.3 parts by weight of sulfur and 0.1-0.3 parts by weight of dipentamethylene thiuram tetrasulfide.
