The invention discloses a modified polyurethane foam heat insulation board and a preparation method thereof, the modified polyurethane foam heat insulation board comprises modified polyurethane foam and at least one heat insulation bag, the heat insulation bag is wrapped in the modified polyurethane foam, the distance between the heat insulation bag and the modified polyurethane foam is b and c, the distance between the heat insulation bags is a, and the distance between the heat insulation bags is a. The volume ratio of the heat insulation bag in the heat insulation plate is 30%-60%. The preparation method comprises the following steps: S1, infiltrating a fiber net into aerogel, performing ultrasonic oscillation to enable the aerogel to coat fibers in the fiber net, filling a grid structure in the fiber net, and then performing freeze drying to obtain a heat insulation bag outer shell; s2, the heat insulation bag outer shell is filled with filler, then the heat insulation bag outer shell is sealed, and a heat insulation bag is obtained; s3, part of the modified polyurethane foam is injected into the mold, then the heat insulation bag is placed into the mold, and the remaining part of the modified polyurethane foam is injected; and S4, after hardening and shaping in the step S3, the heat insulation plate is obtained.
本发明公开了一种改性聚氨酯泡沫隔热板及其制备方法，包括改性聚氨酯泡沫和至少一个隔热包，所述隔热包包裹在改性聚氨酯泡沫内，所述隔热包和改性聚氨酯泡沫的间距为b和c，所述隔热包间的间距为a，隔热包在所述隔热板中的体积比为30％～60％。所述制备方法包括如下步骤：S1：将纤维网浸润到气凝胶中，超声震荡使得气凝胶包覆纤维网中的纤维，填充满纤维网中的网格结构，然后冷冻干燥得到隔热包外壳体；S2：将填充物填充入隔热包外壳体中，然后密封隔热包外壳体，得到隔热包；S3：将改性聚氨酯泡沫注入部分到模具中，然后将隔热包放置入模具中，注入剩余部分改性聚氨酯泡沫；S4：将步骤S3中的硬化定型后，得到所述隔热板。
