1. A cabin pipeline using a super thermal insulation material, comprising an electrically conductive inner pipe, an anti-corrosion coating coated on the electrically conductive inner pipe, a thermal insulation layer formed by the super thermal insulation material wound on the anti-corrosion coating, and a resin sealing layer coated on an outside of the thermal insulation layer;
the electrically conductive inner pipe being an aluminum alloy or a copper alloy;
the anti-corrosion coating being a coating formed after an epoxy coating is cured, wherein the epoxy coating is prepared from following raw materials in parts by weight: an epoxy resin 50-70 parts, a curing agent 10-20 parts, a coupling agent 0.1-0.5 parts, and a filler 20-40 parts, the curing agent being an amine-based curing agent, the coupling agent being any one or a mixture of silane coupling agent KH530, silane coupling agent KH550, silane coupling agent KH560, and silane coupling agent KH570, and the filler being any one or a mixture of titanium white powder, corundum powder and wollastonite powder;
the super thermal insulation material being an aerogel thermal insulation felt, and thermal conductivity at 25° C. being 0.014-0.025 W/(m·K);
the thermal insulation layer comprising a first winding layer and a second winding layer, wherein the first winding layer is formed by winding a strip-shaped super thermal insulation material with a width of 20-30 cm in a clockwise direction, and the second winding layer is wound outside the first winding layer and is formed by winding a strip-shaped super thermal insulation material with a width of 30-50 cm in a counterclockwise direction;
a resin of the resin sealing layer being any one of an epoxy resin, a phenolic resin, a bis-maleimide resin, and a benzoxazine resin.
