摘要
Abstract
Based on the concept of green mine,konjac glucomannan(KGM)is com-pounded with polyacrylamide(PAM),acrylic acid(AA),and coal slurry(SM)to ob-tain the final product(AA-PAM-KGM/SM).The experimental results show that the prepared gel had the best water absorption and retention properties when the KGM:PAM:AA:SM is 1:9:6:5,the amount of crosslinking agent is 6.3%,and the amount of initiator is 0.5%.Infrared spectroscopy analysis shows that graft copolymerization reaction occurrs between each of the components;Scanning electron microscopy ob-serves strong adhesion between coal slurry and KGM skeleton,with uniform and dense element distribution;Through the performance test of flame retardancy and ox-idation resistance,it is proved that this gel can effectively inhibit the generation of harmful gases;Through molecular dynamics simulation,the gelation and flame re-tardant mechanism of fire-resistant gel is thoroughly clarified.The obtained gel can effectively inhibit the oxidation of coal,and is an ideal fire prevention and extin-guishing material.关键词
