PROCESS FOR PRODUCTION OF GASKETS |
摘要 |
<p>The invention provides a process for producing gaskets that is capable of improving the wettability of the metal surface to thereby enhance the tackiness when rubber is anchored to a metal core material without using an adhesive. The process for producing gaskets includes the steps of: forming a metal core material (2) using a stainless steel plate; treating the resulting metal core material (2) with an alkali treating solution; preparing an unvulcanized rubber molded product (1); mounting the metal core material (2) treated in the treating step to the unvulcanized rubber molded product (1); and vulcanizing the rubber-molded product to thereby anchor the elastic material to the metal core material (2) without using an adhesive; characterized in that the alkali treating solution used in the step of alkali treatment comprising the following components (A), (B), and (C):
(A) an alkali metal hydroxide or an alkaline earth metal hydroxide;
(B) an alkali metal silicate or an alkaline earth metal silicate; and
(C) a carboxylate salt.</p> |
