摘要

本研究用发烟硫酸对松炭进行磺化,得到磺化碳。通过元素分析仪、傅里叶变换红外光谱和x射线光电子能谱的表征,表明-SO3H在磺化反应中成功地与松碳骨架结合。采用锥量热法、热重法、扫描电镜、热解-气相色谱-质谱法研究了松碳和磺化碳对木屑板催化碳化抑烟的影响,并探讨了其阻燃机理。通过对峰值放热率、总放热率、排烟率和总烟产物的比较,得出含磺化碳木屑板的性能更优。此外,随着磺化碳的加入,形成了具有强含氧杂化结构和碳水化合物结构的碳层,抑制了木屑板的热解,提高了木屑板的炭产率。

Effects of sulfonated carbon on the catalytic carbonization and smoke suppression of sawdust board
In this study, sulfonated carbon was obtained by sulfonating pine carbon with fuming sulfuric acid. Characterized by elemental analyzer, fourier transform infrared spectroscopy and X-ray photoelectron spectrometry, it showed that –SO3H was successfully bonded onto the pine carbon’ skeleton in the sulfonation reaction. The effects of pine carbon and sulfonated carbon on the catalytic carbonization and smoke suppression of sawdust boards, and its flame-retardant mechanism were investigated by cone calorimetry, thermogravimetric analysis, scanning electron microscopy, and pyrolysis–gas chromatography–mass spectrometry. And the results demonstrated that sawdust boards containing sulfonated carbon showed superior performance, determined by comparing the peak heat release rate, total heat release, smoke release rate, and total smoke product. Furthermore, with the addition of sulfonated carbon, a carbon layer was formed with a strong oxygen-containing hybrid structure and carbohydrate structure, the pyrolysis of sawdust boards was inhibited, and its char yield was increased.

期刊介绍: The Journal of Fire Sciences is a leading journal for the reporting of significant fundamental and applied research that brings understanding of fire chemistry and fire physics to fire safety. Its content is aimed toward the prevention and mitigation of the adverse effects of fires involving combustible materials, as well as development of new tools to better address fire safety needs. The Journal of Fire Sciences covers experimental or theoretical studies of fire initiation and growth, flame retardant chemistry, fire physics relative to material behavior, fire containment, fire threat to people and the environment and fire safety engineering. This journal is a member of the Committee on Publication Ethics (COPE).
