WATER-CROSSLINKABLE FOAM RESIN COMPOSITION AS WELL AS FOAMED BODY AND PRODUCTION METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a water-crosslinkable polyolefin composition that can be expanded at a high expansion ratio.;SOLUTION: A water-crosslinkable foam resin composition is prepared by combining silyl-modified polyolefin and fatty acid amide. The composition may further contain foaming agent (in particular volatile foaming agent) and flame-retardant agent (in particular flame-retardant agent comprising halogen atom and heterocycle) and flame-retardant auxiliary. The weight ratio between the flame-retardant agent and antimony type flame-retardant auxiliary is at a level of former/latter=85/15 to 45/55. The silyl-modified polyolefin may be a polymer obtained by graft-polymerizing a silyl compound comprising hydrolysis-condensable group and ethylenically unsaturated bond, to polyolefin. A foamed body may be produced by first foam-forming the composition and then water-crosslinking the silyl-modified polyolefin with help of the water in the air.;SELECTED DRAWING: None;COPYRIGHT: (C)2016,JPO&INPIT
