Abstract
PURPOSE: To prepare the title article having fine and uniform foams, by foaming a molten foamable resin composition composed of a specific rubber composition, an olefin resin, and a decomposition-type foaming agent.
CONSTITUTION: A lightly crosslinked rubber composition is prepared by heat treating a composition composed of (a) 100 parts by weight of a mixture of (a1) 100W50 parts by weight of a peroxide-crosslinkable olefin copolymer rubber having a Mooney viscosity of 10W120, and (a2) 0W50 parts by weight of a peroxide- decomposition type olefin resin having an MI of 0.1W50, and (b) 5W100 parts by weight of a mixture of (b1) 0W40 parts by weight of a peroxide-non-crosslinkable hydrocarbon rubber having a Mooney viscosity of ≤ 60 and/or (b2) 0W80 parts by weight of a mineral oil softener. The heat treatment is carried out in the presence of an organic peroxide. 5W95 wt.% of the rubber composition thus obtained is compounded with 95W5 wt.% of an olefin resin, and 0.01W5 parts by weight, based on 100 parts by weight of the above mixture, of a decomposition-type foaming agent. The composition thus obtained is molten at 140W250°C, and foamed by injection molding.
