Efficient heat insulation sheet and preparation method thereof
The invention belongs to the technical field of heat insulation, and discloses an efficient heat insulation sheet and a preparation method thereof. The efficient heat insulation sheet comprises a basematerial layer and a coating layer, and the coating layer is sprayed on one side surface of the base material layer, wherein the base material layer is composed of aerogel powder, an infrared opacifying agent and short fibers, and the coating layer is composed of unsaturated resin, an initiator, a coupling agent, a fiber material and hollow glass beads. Unsaturated resin, an initiator, a couplingagent, a fiber material and hollow glass beads are uniformly stirred and mixed to obtain slurry A; aerogel powder, an infrared opacifying agent and short fibers are uniformly stirred and mixed to obtain a mixture B; compression molding is performed on the mixture B to obtain the base material layer; the slurry A is sprayed on the surface of one side of the base material layer, and curing is performed according to a curing process of keeping the temperature of 20-30 DEG C for 1-3 hours and then the temperature of 40-50 DEG C is kept for 2-4 hours; and heat treatment is performed after curing to obtain the high-efficiency heat insulation sheet. The obtained heat insulation sheet achieves the efficient heat insulation and heat preservation effects in different medium-high temperature sections.
本发明属于隔热技术领域，公开一种高效隔热片及其制备方法。包括基材层、涂料层，涂料层喷涂在基材层的一侧面；其中，所述基材层由气凝胶粉、红外遮光剂、短纤维组成，所述涂料层由不饱和树脂、引发剂、偶联剂、纤维材料、空心玻璃微珠组成。将不饱和树脂、引发剂、偶联剂、纤维材料、空心玻璃微珠搅拌混合均匀，得到浆料A；将气凝胶粉、红外遮光剂、短纤维搅拌混合均匀，得到混合料B；将混合料B压制成型，得到基材层；将浆料A喷涂于基材层的一侧表面，然后按照先20~30℃保温1~3 h、再40~50℃保温2~4 h的固化工艺进行固化；固化完成后进行热处理，即得高效隔热片。本发明所得隔热片实现了在不同中高温温度段高效的隔热保温效果。
