Preparation and characterization of a novel intumescent flame retardant
摘要
Abstract
The hyperbranched product (HPAE1) with terminated hydroxyl was prepared based on trimethyl-olpropane and AB2 monomer synthesized by methyl acrylate and diethanolamine using p-toluene sulfonic acid as catalyst. Final y, a novel intumescent flame retardant HPAE1-P was synthesized using HPAE1 and phos-phorylation agent (phosphorus pentoxide and phosphoric acid) via partial phosphorylation reactions. The molecu-lar structure and thermal stability of the HPAE1-P were characterized by FTIR, elemental analysis, 1H NMR and TGA. The results showed that the main C skeleton of HPAE1 did not change, and hydroxyl was partial y phosphorylated. The flame retardant had good thermal stability. The application tests showed that flame retar-dant performance of the finished fabric increased, LOI could reach 30.5%, flame retardant grade reached the B1 level.关键词
