MELTBLOWN FIBER EXTERIOR HEAT INSULATING MATERIAL FOR INDUSTRY WITH EXCELLENT UV STABILITY AND OXIDATION STABILITY

摘要

The present invention relates to a meltblown fiber exterior heat insulating material for industry with excellent UV stability and oxidation stability. The heat insulating material is a meltblown fiber web, comprising: a meltblown fiber layer for blending 10-50 wt% of a thermoplastic resin meltblown fiber and 50-90 wt% of a filament; and a protective layer formed on one surface or both surfaces of the meltblown fiber layer, and the protective layer comprising one layer or two layers which are made of a nonwoven web or a woven fabric treated with a UV stabilizer and an oxidation stabilizer.;COPYRIGHT KIPO 2015
