Title:
スパークリングワイン用のコンポジットコルク材料の栓およびその製造方法
Document Type and Number:
Japanese Patent JP5576119
Kind Code:
B2
Abstract:
Stoppers made from composite material for sparkling wines consisting of two types of cork agglomerate which are closely bonded and produced from two ranges of granulates of different granulometry, where the joining surface between the two agglomerates is irregular due to their interpenetration. A production process of such stoppers by individual molding (piece by piece), where there is simultaneous feeding of two types of granulate and respective additives into a mold. The mold is then closed and the material compressed and heated for an appropriate time for polymerization. The granulates used are normally treated with a reactive agglomerant consisting of, for example, quasi-prepolymer based on TDI or quasi-prepolymer based on MDI base. After de-molding, the unfinished stopper is stabilized, and later machined to the final dimensions.
