生物基改性纳米P-N-Si协效阻燃聚氨酯泡沫的制备与研究
Preparation and Study of Bio-based Modified P-N-Si Nanometer Co-efficent Flame Retardant Polyurethane Foam
摘要
Abstract
Rigid polyurethane foam(PU)is an organic polymer material with a large number of repeating structural unit carbamate groups(—NHCOO—)in the main chain,which is very easy to be ignited by fire.In order to improve its combustion performance,in this study,m-SiO2 was used as the silicon source,phytic acid(PA)was used as the acid source,4-aminopyridine(4-AP)was used as the nitrogen source,the transition metal ion Zn2+was selected as the catalytic carbon forming agent,and the biobased modified P-N-Si flame retardant m-SKAPA-Zn was prepared by a layer-by-layer modification.m-SKAPA-Zn was respectively added into the PU at the mass fraction of 5%,10%and 15%to prepare flame retardant PU composites.The results showed that the flame retardant properties increased with the increase of m-SKAPA-Zn addition,the LOI of PU material with 15%m-SKAPA-Zn increased to 22.6%,the UL-94 test could reach the V-1 rating,and the smoke density level was reduced by 37.5%.m-SKAPA-Zn showed better flame retardancy and smoke inhibition effect.关键词
