Document Type and Number:
WIPO Patent Application WO/2020/045907
Kind Code:
A1
Abstract:
The present invention relates to a manufacturing method for a PE or PP pipe containing sulfur polymer cement, and more specifically, to a manufacturing method for a PE or PP pipe containing sulfur polymer cement, the method using a combination of two techniques, one for homogeneously blending the sulfur polymer cement into the material for forming a pipe, and the other for treating toxic sulfur gases generated from the forming process, and to a PE or PP pipe manufactured by the manufacturing method. The manufacturing method for a PE or PP pipe containing sulfur polymer cement of the present invention comprises: a PE or PP blend preparation step (100) for forming a PE or PP blend using PE or PP in particle or powder form, and supplemental ingredients; a forming step (200) for melt-extruding the PE or PP blend to form a PE or PP pipe; and a production step (300) for cutting the PE or PP pipe drawn out in the forming step to a predetermined length to form products, wherein the PE or PP blend preparation step (100) consists of additionally adding the sulfur polymer cement to be mixed together, to prepare the PE or PP blend containing the sulfur polymer cement.
