Abstract

PURPOSE: A lubricating release agent used in a mold for casting a glass product having improved characteristics, obtained by kneading a solid lubricant, a binder, a reaction inhibitor, and an air-drying accelerator with water.
CONSTITUTION: A release agent capable of forming a film having improved mold release property and durability on application to the inner surface of a mold in preparing a glass product by casting molten glass in the mold. The release agent is prepard by kneading 6.0W80.0wt% granular graphite powder of particle size ≤20μ as a solid lubricant, 18.0W40;0wt% aluminum primary phosphate as a binder, 0.5W4.0wt% pyridine or a derivative thereof or a chromium compound, e.g. chromic anhydride, sodium chromate or sodium dichromate, as a reaction inhibitor and 0.05W0.4wt% alkaline earth metallic oxide, e.g. MgO, BaO or CaO, as an air-drying accelerator with 25.6W75.45wt% water as a solvent.
