Claim 1:
2. A preparation method of the cabin pipeline of claim 1, comprising following steps of:
1) degreasing and sandblasting a surface of the electrically conductive inner pipe, and pre-heating to 170° C.-230° C.;
2) spraying an epoxy coating on the surface of a preheated electrically conductive inner pipe, a spraying thickness being 20-50 μm, and after spraying, curing at 220° C.-240° C. for 0.5-1.5 h to form the anti-corrosion coating;
3) winding the super thermal insulation material on the anti-corrosion coating to form a thermal insulation layer; and
4) Coating a surface of the thermal insulation layer with the resin, a coating thickness being 2-3 mm, and curing at 220° C.-240° C. for 0.5-1.5 h to form the resin sealing layer, to obtain the cabin pipeline using the super thermal insulation material.
