The invention relates to the field of wood product material research and development industry, and discloses a wooden heat preservation refractory plate. Prepared ether gel and refractory powder are mixed to prepare an inorganic nonmetal-metal composite material; the composite material is loose in structure, contains a large number of nanometer gaps, is good in heat preservation and insulation effect, is hydrophobic in surface, and is added into wood flour, and the mixture is subjected to hot pressing to form a plate, so that the wood heat preservation plate is fireproof, and the tensile strength, the impact strength and other mechanical properties of the plate are improved. The prepared heat preservation refractory plate is light in weight, low in water absorption expansion rate and excellent in thermal insulation and fire resistance, the heat conductivity coefficient is 0.038-0.040 W/mK at 25 DEG C, and the thermal insulation refractory plate is non-toxic, pollution-free and good indegradability and is a light, efficient, green and environment-friendly heat insulation refractory building material.
本发明涉及木制品材料研发产业领域，公开了一种木质保温耐火板，将制备得到的醚凝胶与耐火粉末混合进一步制备无机非金属‑金属复合材料，该复合材料结构疏松，含有大量的纳米空隙，保温隔热效果好，且表面憎水，将该材料添加至木粉中，进行热压为板材，不仅赋予了木质保温板的耐火性，还能够提高板材的抗拉强度、抗冲击强度等力学性能。制备得到的保温耐火板质轻、吸水膨胀率低，具有优异的保温、耐火性能，25℃时，导热系数为0.038‑0.040W/mK，且无毒、无污染，降解性好，是一种轻型高效绿色环保的保温耐火建筑材料。
