Abstract

The invention discloses an ethylene propylene rubber cable insulating material for ship and ocean use and a manufacturing method thereof. The insulating material comprises by weight: 11 parts of ethylene propylene rubber 2470; 9 parts of ethylene propylene rubber 4044; 1.0-1.5 parts of high pressure polyethylene; 0.5-1.0 part of dicumyl peroxide; 0.3-0.4 part of triallyl isocyanurate; 0.5-0.8 part of 2-mercaptobenzimidazole; 1-1.5 parts of titanium dioxide; 1.0-1.5 parts of paraffin oil; 1.0-1.5 parts of zinc oxide; 0.6-1.0 part of microcrystalline wax; 0.2-0.5 part of stearic acid; 1-2 partsof white carbon black; 10-15 parts of superfine talc powder; and 12-16 parts of modified calcined argil. The method consists of the steps of: conducting uniform banbury mixing to ethylene propylene rubber and high pressure polyethylene; then adding titanium dioxide and the like in order for uniform mixing; carrying out triangle bag packaging with an open mill for 7 times, then filtering rubber, and putting the filtered rubber in a banbury mixer and adding an antioxidant for mixing well; finally conducting triangle bag packaging in an open mill for 5 times and extruding rubber sheets. The insulating material has the advantages of low smoke, free of halogen, flame retardation, high mechanical strength and high insulation resistance.

Description

technical field [0001] The invention relates to an insulation material for cables, in particular to an ethylene-propylene rubber cable insulation material for ships and oceans; the invention also relates to a manufacturing method of the ethylene-propylene rubber cable insulation material for ships and oceans.
