USE OF BROMINATED LIGNIN SULFONATE FOR FLAME PROOFING AND THE PRODUCTION OF FLAME PROOF BONDED ARTICLES

摘要

Brominated lignin sulfonate and brominated kraft lignin are used for flameproofing inflammable material. The substrate may be coated or soaked with an aqeuous slurry or alkaline solution of brominated lignin sulfonate or brominated kraft lignin. It is also possible to bond particulate or fibrous inflammable material using a bonding composition containing a prepolymerisate and brominated lignin sulfonate or brominated kraft lignin.
