Abstract

PURPOSE: To obtain the titled foamy body having an excellent cushion quality and a rebounding elasticity with a small quantity of raw material by a method wherein a rubber sheet containing synthetic rubber and a bubbling agent in a specific ratio is filled in a molding mold, it is blocked with a covering mold to be heated and pressed and then, it is cooled and thereafter, a metallic mold is released.
CONSTITUTION: A rubber sheet having as main components, natural or synthetic rubber (for example: acrylonitrile butadiene rubber) of 100pts.(wt.), a bubbling agent (example: azo dicarbonic amide) of 15W80pts., a bridge forming agent (preferably dicumyl peroxide) of preferably 0.5W15pts. is filled into a mold and it is blocked tightly with a covering mold to be heated, and pressed (preferably 100W 170kg/cm, 130W200°C) and to be bridge formed and then, it is cooled (for example, it is favorable to feed water to a jacket of a metallic mold and to drop the temperature upto 50W100°C), and thereafter, the metallic mold is released. With this, a high foamy body having a 0.002W0.03 low density and 30W50 multiplication is obtained.
