Abstract

The invention discloses an ethylene propylene rubber insulation material for longitudinal high-voltage watertight cables of ships and warships and a production method thereof. The method comprises the following steps: adding the ethylen e-propylene-diene mischpolymere, age resister and fire retardant into a banbury for banburying for 3.5min; adding argil, white carbon black and paraffin wax for continued banburying for 2min; adding active agent, and discharging after banburying for 1.5min; filtering the rubber compound with a three-layer filter screen (namely a 60 mesh filter screen, a 60 mesh filter screen and a 80 mesh filter screen) on a rubber filter; and beating into cornucopla on a double-roller mill, adding vulcanizer and co-crosslinker, then beating into cornucopla for 7 times, grinding and slicing after finishing the steps, and then cooling, wherein the materials are as follows in parts by weight: 100 parts of ethylen e-propylene-diene mischpolymere, 1-5 parts of vulcanizer, 1-4 parts of age resister, 15-70 parts of fire retardant, 0.5-10 parts of active agent, 10-20 parts of argil and 2-4 parts of paraffin. The prepared insulation material has the characteristics of low smoke, no halogen, fire resistance, high machinery strengthen, and high insulation resistance, good flexibility, elasticity and viscosity, and can be used for the ships and warships.

Description

technical field [0001] The invention relates to an insulating material for power cables, in particular to an ethylene-propylene rubber insulating material for longitudinal high-voltage watertight cables of ships. Background technique [0002] EPDM rubber is widely used as wire and cable insulation materials due to its excellent electrical properties, high heat resistance and aging resistance, and good low temperature flexibility. [0003] On May 20, 2009, the Chinese invention patent application with the publication number CN101434728 disclosed a kind of ultraviolet light crosslinked EPDM cable insulation material and its preparation method, which is characterized in that 100 parts of EPDM rubber, 100-120 parts of inorganic filler, 0.5-5.0 parts of ultraviolet photoinitiator, 0.5-5.0 parts of multifunctional crosslinking agent, 5.0-10.0 parts of softener, 0.8-1.2 parts of silane coupling agent and 0.01-1.0 parts of composite antioxidant Mix and extrude uniformly at 100-150°...
