摘要
餐厨垃圾生产柴油中产生酸化油渣固废(AR)。采用红外光谱(FTIR)法对AR进行分析,认为AR具有较好的阻燃成炭性能。将AR与多聚磷酸铵/三聚氰胺/季戊四醇(APP/MEL/PER)膨胀阻燃体系(IFR)复配,协效阻燃环氧树脂(EP),用极限氧指数法(LOI)、垂直燃烧法(UL94)对其阻燃性能进行了检测,并通过对燃烧残渣的分析讨论了阻燃机理。结果表明,当APP/MEL/PER/AR质量分数为25%,其中AR的质量分数为2%~6%时,阻燃EP的LOI达到30%,具有良好的阻燃性能,并降低了阻燃剂及阻燃材料总体成本。研究成果对餐厨垃圾能源化起到积极推动作用。
To protect the environment and use the acid residue( AR) from kitchen waste regeneration,the AR was analyzed by infrared spectrum( FTIR) firstly. Then,the AR was used as char forming agent in the ammonium phosphate /melamine /pentaerythritol( APP /MEL /PER) intumescent flame retardant( IFR) system. The flame-resistant performance of the synergistic flame retarding epoxy resin( EP)( AR /IFR /EP) was tested by means of limited oxygen index( LOI) and vertical combustion method. The flame-resistant mechanism was also discussed based on analysis of the residue. Results indicated that,the LOI value of IFR /AR /EP( IFR + AR: 25wt%; AR: 2 ~ 6 wt%) reached 30%,indicating a good flame-resistant performance and lower cost. These results play a positive role in promoting the energy regeneration of kitchen waste.
