Abstract

PURPOSE:To manufacture the captioned sheet excellent in physical properties, processing properties, etc. by molding a resin composition in the form of a sheet at a temperature at which a foaming agent, a crosslinking agent, etc. which are mixed in do not make any resolution and reaction and then by applying crosslinking and foaming processing thereto. CONSTITUTION:The resin composition wherein olefin resin of 100pts. (weight part: the same is applied to the following), an inorganic filler of 40-120pts., a lubricant of 0.6-2pts., a silane coupling agent of 0.5-1.5pts., the crosslinking agent of 0.6-2pts., the foaming agent of 1-5pts., an auxiliary agent for crosslinking of 0-5pts. and phase-soluble resin of 0-20pts. are compounded together is molded by extrusion and thereby a sheet which is not yet crosslinked and foamed is formed. Next, the sheet 1 thus formed is held between a pair of endless belts 2 and 2' and carried thereby and is subjected to the respective treatment at a heating part (a) for crosslinking, a heating part (b) for foaming, a surface-cooling part (c) and an expanding part (d) in the cource of processing, and thus filled and foamed sheet having the skin structure and foaming multiplication rate of about 2-5 times is manufactured.
