METHOD OF MANUFACTURING MOLDED PRODUCT OF SILANE CROSSLINKED POLYETHYLENE RESIN, METHOD OF MANUFACTURING ROD-SHAPED MOLDED PRODUCT, AND MANUFACTURING APPARATUS THEREFOR |
| 摘要 |
A method of manufacturing a molded product of a silane crosslinked polyethylene resin includes the steps of: melting a silane crosslinked polyethylene resin; extrusion-molding the melted resin; bringing a surface of a molded product obtained by the extrusion molding into contact with an oil-soluble dye solution before at least the surface solidifies; separating the molded product from the oil-soluble dye solution; and cooling the molded product separated from the oil-soluble dye solution. According to the method of manufacturing a molded product of a silane crosslinked polyethylene resin, a molded product of a uniformly-colored silane crosslinked polyethylene resin can be obtained without causing scorching even if a silanol condensation catalyst is blended for molding, and also without impairing productivity since molding and coloring are sequentially carried out. |
