Waterborne external release agent, and molding process for vulcanization of tyres or other rubber articles |
| abstract |
An aqueous external release agent for the production of tires and other rubber articles is described which contains 5 to 35% by weight of diatomaceous earth, 0.5 to 6% by weight of pyrogenic hydrophobic silica, 0.1 to 2% by weight of nonionic surfactant, Contains 0.2 to 3 wt .-% of a binder, 0.1 to 3 wt .-% dye, 0 to 5 wt .-% ethyl alcohol and the rest of water. Preferred binders are styrene-maleic acid or styrene-maleic anhydride copolymers and in particular their ammonium salts. This external release agent is used in processes for the molding and vulcanization of tires and other rubber articles, whereby it is sprayed onto the blank with the aid of air atomizing guns before molding and vulcanization are carried out. A very good separation effect is achieved without the vulcanization being impaired. The fact that only very small amounts of external release agents are required means that cleaning of the mold and thus an interruption of the production process is required much less frequently than when using conventional external release agents. |
