    • Proposed is a method for the preparation of a monolithically integrated composite cured body consisting of a part of cured silicone rubber composition and a part of a silicone-epoxy resin composition firmly bonded together without using any primer or adhesive by first curing either one of the compositions in a metal mold and then bringing the other of the compositions into direct contact with the already cured part in the metal mold to be cured thereon. Firm bonding between the parts can be obtained when the silicone rubber composition is of the peroxide-curable or the hydrosilation-curable type and the silicone-epoxy resin composition comprises: (a) a curable epoxy resin; (b) an alkenyl group-containing organopolysiloxane; (c) an organohydrogenpolysiloxane; (d) an organosilicon compound having at least one silanol group in a molecule; (e) an organic aluminum compound such as aluminum benzoate; and (f) a compound of a platinum group metal such as chloroplatinic acid, each in a specified weight proportion.
    • 提出了一种制备整体式复合固化体的方法,该复合固化体由一部分固化的硅橡胶组合物和一部分硅氧烷 - 环氧树脂组合物组成,该硅氧烷环氧树脂组合物通过首先固化组合物中的任何一种而不使用任何底漆或粘合剂而牢固地结合在一起 在金属模具中,然后使另一个组合物与待固化的金属模具中的已固化部分直接接触。 当硅橡胶组合物为可过氧化物固化或氢化硅烷化固化型且硅氧烷 - 环氧树脂组合物包含:(a)可固化环氧树脂; (b)含链烯基的有机聚硅氧烷; (c)有机氢聚硅氧烷; (d)分子中具有至少一个硅烷醇基的有机硅化合物; (e)有机铝化合物,例如苯甲酸铝; 和(f)铂族金属如氯铂酸的化合物,各自以规定的重量比例。
