FLAME RETARDANT CHEMICALLY BONDED NONWOVEN FABRIC

摘要

PROBLEM TO BE SOLVED: To provide a flame retardant chemically bonded nonwoven fabric which does not cause a metal corrosion problem even in a high temperature and high humidity condition and has high flame retardancy.SOLUTION: The flame retardant chemically bonded nonwoven fabric includes ammonium polyphosphate coated with silane and a metal hydroxide salt as a flame retardant and is obtained by compounding a fire retardant resin obtained by dispersing the flame retardant in a resin with a fiber sheet. When the amount of the flame retardant is to be 100 pts.mass, it is preferable that the amount of ammonium polyphosphate coated with silane is in the range of 40-60 pts.mass and the amount of the metal hydroxide salt is 40-60 pts.mass. This nonwoven fabric has a fire retardant of V-0 in accordance with the vertical method of UL-94 standard and does not generate rust even when it is brought into contact with a nickel metal.
