Fireproof thermal insulation material structure for ship

The utility model provides a fireproof thermal insulation material structure for ships, which comprises a common foam layer and a polymer skin layer, a high flame retardant foam layer is arranged between the common foam layer and the polymer skin layer, and the high flame retardant foam layer is a polyisocyanurate or polyurethane material layer. A high-flame-retardant foam layer made of polyisocyanurate or polyurethane materials is used for wrapping a ship fuel tank body or a pipeline with explosiveness; large fire disasters caused by ignition of the thermal insulation layer of the tank body due to spark falling during continuous welding, cutting and other operations around the thermal insulation layer after various liquid tank thermal insulation layers of the ship are mounted on the ship body and serious explosion possibly caused during tank body or pipeline maintenance after later use can be avoided; the flame retardant level of the structure can reach the B, C and D levels of EN 13501-1: 2002 or the GB-862
