METHOD FOR PRODUCING CROSSLINKED RUBBER

Provided is a method for producing a cross-linked rubber with which it is possible to easily produce a cross-linked rubber of a laminated molded body with excellent dimensional accuracy even when a general-purpose non-cross-linked rubber composition is used. The method for producing a crosslinked rubber involves heating an uncrosslinked rubber laminated molded body in a liquid to produce a crosslinked rubber laminated molded body, in which the temperature and pressure of the liquid are controlled, the uncrosslinked rubber laminated molded body is heated so as not to exceed a saturated vapor pressure, and the uncrosslinked rubber laminated molded body is heated so as not to exceed a saturated vapor pressure. Equation (1) is used to obtain an equivalent crosslinking amount every prescribed time from the start of heating and accumulate the equivalent crosslinking amount to calculate an accumulated crosslinking degree, and when the crosslinking degree of a crosslinked rubber laminated molded body reaches a necess
