摘 要:为了降低煤矿资源开采过程中煤自燃现象发生的几率,以改性纳米材料(GCX-2)、聚醚多元醇(PTMG)、甲基膦酸二甲酯(DMMP)、二羟甲基丙酸(DMPA)、三亚乙基二胺(TEDA)、甲苯二异氰酸酯(TDI)和二苯基甲烷二异氰酸酯(MDI)为主要原料,研制了一种适合煤矿区防火阻燃的改性聚氨酯封堵材料,并考察了GCX-2对阻燃材料性能的影响。结果表明:研制的阻燃材料具有良好的固结性能、遇水膨胀性能和抗压强度,能够满足煤矿井下施工的基本需求。另外,研制的阻燃材料还具有良好的抗老化性能、抗静电性能以及阻燃性能,当GCX-2的质量分数为6%时,阻燃材料的有焰燃烧时间和无焰燃烧时间分别可以降低至1.5 s和3.9 s,明显低于AQ 1090—2011中要求的阻燃性能标准值,阻燃效果较好。In order to reduce the probability of spontaneous combustion of coal during the coal mining process,a modified polyurethane blocking material suitable for fire protection and flame retardancy in coal mines was developed with modified nano material GCX-2,polyether polyol PTMG,dimethyl methyl phosphonate DMMP,dimethylol propionic acid DMPA,triethylenediamine TEDA,toluene diisocyanate TDI and diphenylmethane diisocyanate MDI as main raw materials.And the influence of modified nanomaterial GCX-2 on the properties of flame-retardant material was investigated.The results showed that the developed flame-retardant material had a good consolidation performance,water expansion performance and compressive strength,which could meet basic needs of underground construction in coal mines.In addition,the developed flame-retardant material also had a good anti-aging performance,anti-ESD performance and flame-retardant performance.When the mass fraction of GCX-2 was 6%,the flame burning time and flameless burning time of the flame-retardant material could be reduced to 1.5 s and 3.9 s respectively,significantly lower than the flame-retardant performance standard value required in the industry standard AQ 1090—2011,and the flame-retardant effect was good.
