Lightweight fiber heat insulation plate and preparation method thereof
The invention relates to the technical field of building materials, in particular to a lightweight fiber heat insulation plate and a preparation method thereof. The lightweight fiber heat insulation plate comprises the following components in parts by weight: 20-70 parts of inorganic fibers; 20-70 parts of expanded perlite; 8-10 parts of a binding agent; 0.5-2 parts of a foaming agent; the bindingagent comprises an organic binding agent and an inorganic binding agent. Under the synergistic effect of the components, the light fiber heat insulation plate can obtain better heat conduction performance and mechanical performance under the condition of smaller volume density. Experimental results show that the light fiber heat insulation plate prepared by the method is small in volume weight, the heat conductivity coefficient does not exceed 0.08 W/(m.K), and the heat insulation effect is excellent; the compression strength after sintering is not lower than 50KPa, and the mechanical property is better.
本发明涉及建筑材料技术领域，尤其涉及一种轻质纤维隔热板及其制备方法。所述轻质纤维隔热板按重量份数计包括：无机纤维20～70份；膨胀珍珠岩20～70份；结合剂8～10份；发泡剂0.5～2份；所述结合剂包括有机结合剂和无机结合剂。本发明提供的轻质纤维隔热板在各组分的协同作用下，可以在体积密度较小的情况下，获得较优的导热性能和力学性能。实验结果表明，本发明制备的轻质纤维隔热板容重小，导热系数不超过0.08W/(m·K)，绝热效果优异；烧后耐压强度不低于50KPa，力学性能较优。
