摘要： 针对现有防火门大多仅有防火功能，户门行业缺少兼具绿色环保且集防火、防盗、防烟、美观功能于一体的入户门等问题，研发筛选新型门芯材料，在保证其优异的耐火性能基础上，着重突出了材料的绿色环保、无毒无害属性，并研制典型结构，运用先进的加工工艺，设计同时具备防火、防盗、防烟功能的入户门。本研究对门芯材料、门芯结构、成品门进行了燃烧等试验，并对特定结构的防火门进行了数值模拟。结果表明：该入户门能够通过所有相关的试验测试，完全满足耐火隔热性（≥1.5 h，背火面平均温升≤140 ℃）、耐火完整性（背火面未出现火焰、裂缝）、反复启闭耐久性、防烟性能以及防盗性等各项关键指标的标准要求。

Abstract: In response to the problem that most existing fire doors only have fire prevention functions and the household door industry lacks green and environmentally friendly entrance doors that integrate fire prevention, theft prevention, smoke prevention, and aesthetic functions, a new type of door core material has been developed and selected. On the basis of ensuring its excellent fire resistance performance, the material's green and environmentally friendly, non-toxic and harmless properties are highlighted, and a typical structure is developed. Advanced processing technology is used to design entrance doors that have fire prevention, theft prevention, and smoke prevention functions at the same time. This study conducted combustion tests on the core materials, core structures, and finished doors, as well as numerical simulations of fire doors with specific structures. The results indicate that the entrance door can fully meet the standard requirements for key indicators such as fire resistance and insulation (≥1.5 hours, average temperature rise at the unexposed side≤140 ℃), fire integrity (no flames or cracks at the unexposed side), durability of repeated opening and closing, smoke resistance, and theft prevention.
