Background
Currently, spray polyurethane insulation systems have been used for fuel tanks and other cryogenic tanks in existing ships. However, the low temperature of the tank when loaded with low temperature cargo will significantly increase the stress and affect the adhesion between the sprayed insulation and the tank, eventually causing the insulation system to detach from the surface of the tank. The surface separation phenomenon may cause cracking and delamination of the polyurethane insulation material at the same time, ultimately affecting the performance of the entire insulation system. To avoid this problem, the current common approach is to add a mesh of different materials to maintain the entire system after the insulation is sprayed or sprayed to a final thickness. However, the design brings problems, and the addition of the mesh cloth in the spraying heat preservation affects the tensile strength of the heat preservation layer material in the direction vertical to the mesh cloth, and causes the separation of the heat preservation layers; the addition of the mesh cloth on the outermost layer of the sprayed heat-insulating material causes excessive loss of the surface protective material and influences the appearance.
