Processing apparatus for vacuum heat-insulating plate, aerogel-modified polyurethane foam thermal insulation plate, and preparation method therefor

An aerogel-modified polyurethane foam thermal insulation plate, comprising a polyurethane foam core and at least one thermal insulation pack, wherein the at least one thermal insulation pack is disposed inside of the polyurethane foam core, polyurethane foam wraps the at least one thermal insulation pack, and a volume ratio of the at least one thermal insulation pack in the aerogel-modified polyurethane foam thermal insulation plate is 10%-90%;

• the at least one thermal insulation pack comprises an outer shell formed by an enclosure of a barrier film having a gas barrier effect, the outer shell is filled with a thermal insulation material and at least one gas suction pack, the thermal insulation material comprises 1 wt %-60 wt % of an aerogel and 40 wt %-99 wt % of an inorganic fiber;
• the at least one gas suction pack is filled with a metal oxide, the metal oxide comprises calcium oxide, a set amount of the at least one gas suction pack is determined according to an area of the at least one thermal insulation pack, and the at least one gas suction pack is controlled to be ≤5 g/m2;
• and
• a heat conductivity coefficient of the at least one thermal insulation pack is 0.001 w/m·k-0.010 w/m·k.
