对比例1
制备同实施例一样结构的防火门板，不同之处在于珍珠岩保温板1的原料中使用碳酸钙粉而不是使用本发明所述的改性碳酸钙粉。
所述的珍珠岩保温板由如下重量份的原料成分通过热压成型方法制成：
珍珠岩50份；酚醛树脂60份；水玻璃25份；改性碳酸钙粉25份；固化剂磷酸硅8份；可再分散性乳胶粉8份；硬脂酸钙2份。
对比例2
制备同实施例一样结构的防火门板，不同之处在于珍珠岩保温板1采用市售普通的珍珠岩保温板，而不是按本发明所述方法制备得到的珍珠岩保温板。
试验测试：将实施例1～3以及对比例1～2制备得到的防火门板按GB_12955-2008规定进行耐火极限测试，测试结果如表1所示。
表1.耐火极限测试试验结果
耐火极限(h)
实施例1制备得到的防火门板 2.4
实施例2制备得到的防火门板 2.2
实施例3制备得到的防火门板 2.1
对比例1制备得到的防火门板 0.9
对比例2制备得到的防火门板 0.7
由表1耐火极限数据可以看出，本发明所述的厚度仅仅为40mm厚的防火门板的耐火极限为2.0以上，远远高于现有国标的最高等级甲级防火门1.5h。由上述实验数据可以说明，本发明所述的防火门板的防火性能显著，且其厚度仅仅为40mm，用料少，可以大大节约生产成本。
此外，从对比例1和2数据可以看出，对比例1和2制备得到的防火门板的耐火极限远远小于实施例1制备得到的防火门板，这说明采用本发明所述原材料制备得到的珍珠岩保温板用于防火门板可以显著提高防火性能，尤其是在珍珠岩保温板制备过程中加入改性碳酸钙粉原料，可以大幅提升防火门板的防火性能。
