The invention discloses a mineral wool formula for ships. The mineral wool formula comprises, by weight, 80-125 parts of silicon dioxide, 30-75 parts of magnesium oxide, 15-25 parts of zinc oxide, 16-26 parts of quartz sand, 10-17 parts of calcium chloride hexahydrate, 10-17 parts of quick lime, 2-3 parts of nanopore aerogel, 10-17 parts of expanded perlite, 13-18 parts of silica powder, 7-18 parts of bentonite and 10-13 parts of pure polyurea. Through mutual cooperation of designed silicon dioxide, calcium chloride hexahydrate, quick lime, silica powder, expanded perlite, rutile titanium dioxide, a centrifugal roller, a second motor, a first motor and a centrifugal cylinder, the problem that based on the existing mineral wool fiber centrifugal fiber forming device, in operation process, mineral wool fiber melt is attached to a centrifugal roller, the melt forms chemical fibers under the action of a centrifugal force of the centrifugal roller, and due to the fact that the centrifugal force applied to the melts by the centrifugal roller is limited, the lengths of chemical fibers are short, and the thermal inertia and heat insulation performance of mineral wool do not meet the usingrequirements is solved.
