Abstract
PURPOSE: An uncured polyolefin film containing a curing agent is laminated with cellulosic paper, heated under pressure to form integral structure and then cured, thereby producing said laminated paper suitably used for cable insulation because of its reduced swelling in oil.
CONSTITUTION: Polyolefin film 2 containing a curing agent, which is extruded from extruder 1 at a temperature lower than the decomposition point of the curing agent, is put between sheets of insulation kraft paper 3, 3 while the film is soft, fused by pressing with heated rolls 4, and then sent into chamber 5 that is heated over the decomposition point of the curing agent to effect the crosslinking of the film. After cured, the film is wound on reel 6. The final heating for curing may be effected after the uncured film is taken up on the reel. Further the addition of 0.5 W 5 parts by wt of a functional monomer along with the curing agent increases the resistance to oil.
