Vacuum composite insulation board with layered pore structure and preparation method of vacuum composite insulation board
The invention relates to a vacuum composite insulation board with a layered pore structure and a preparation method of the vacuum composite insulation board. The vacuum composite insulation board withthe layered pore structure is prepared from nano oxide particles, a porous metal organic framework material, an opacifying agent and an adhesive. The preparation method comprises the following stepsof: mixing glass fibers, a dispersing agent and water to obtain slurry; adding a precursor and ammonia water to the slurry; performing stirring to form nano oxide particles on the surface of the glassfibers in situ; performing filtering, mixing and stirring a filtered material, the porous metal organic framework material, the opacifying agent and the adhesive; feeding the mixed materials into a pressing machine for pressing and molding to obtain a core material; drying the prepared core material; packaging the dried core material by using a packaging material, and performing vacuumizing to obtain the vacuum composite heat insulation board with the layered pore structure. The vacuum composite thermal insulation board prepared by the method has a micropore-mesopore-macropore layered pore structure; pores are not communicated with one another and are uniformly distributed; and the thermal insulation board is low in thermal conductivity and high in mechanical strength.
本发明涉及一种具有多级孔结构的真空复合隔热板及其制备方法，具有多级孔结构的真空复合隔热板采用纳米氧化物颗粒、多孔金属有机框架材料、遮光剂、胶黏剂制备得到。其制备方法包括如下步骤：将玻璃纤维、分散剂和水混合后得到料浆，向其中加入前驱体和氨水，搅拌后在玻璃纤维表面原位形成纳米氧化物颗粒，过滤后将过滤物与多孔金属有机框架材料、遮光剂和胶黏剂混合搅拌，将混合好的物料送入压制机中压制成型，得到芯材，将制得的芯材进行烘干处理，再使用包装材料包装抽真空后即可得到具有多级孔结构的真空复合隔热板。本发明制得的真空复合隔热板具有微孔‑介孔‑大孔的多级孔结构，气孔互不贯通，分布均匀，隔热板的热导率低、力学强度高。
