Title (EN) METHOD FOR MANUFACTURING RESIN FOR THIOURETHANE-BASED OPTICAL MATERIAL USING UNIVERSAL POLYISOCYANATE COMPOUND, RESIN COMPOSITION, AND OPTICAL MATERIAL MANUFACTURED THEREBY
(FR) PROCÉDÉ PERMETTANT DE FABRIQUER UNE RÉSINE DESTINÉE À UN MATÉRIAU OPTIQUE À BASE DE THIOURÉTHANE EN UTILISANT UN COMPOSÉ DE POLYISOCYANATE UNIVERSEL, COMPOSITION DE RÉSINE ET MATÉRIAU OPTIQUE AINSI FABRIQUÉ

Abstract: front page image
(EN)The present invention relates to a method for manufacturing a high-quality thiorethane-based optical material by using a universal polyisocynate compound, a resin composition therefor, and an optical material manufactured thereby. The present invention provides the thiourethane-based optical material, which is not subject to whitening of the edge of the lens or polymer imbalance, by controlling a polythiol compound obtained from the manufacturing process to be pH 3.1-7, in order to resolve the existing problem of whitening, which occurs by an adhesive agent melting from an adhesive tape when casting the lens.
(FR)La présente invention concerne un procédé permettant de fabriquer un matériau optique à base de thiouréthane de grande qualité en utilisant un composé de polyisocyanate universel. La présente invention concerne en outre une composition de résine associée et un matériau optique ainsi fabriqué. La présente invention produit le matériau optique à base de thiouréthane qui n'est soumis ni à un blanchissement du bord de la lentille, ni à un déséquilibre de polymère en régulant le pH d'un composé de polythiol obtenu à partir du processus de fabrication a une valeur comprise entre 3,1 et 7, ce qui permet de résoudre le problème actuel du blanchissement qui se produit lorsqu'un agent adhésif coule d'une bande adhésive au moment du moulage de la lentille.
(KO)본 발명은, 범용의 폴리이소시아네이트화합물을 사용하여 고품질의 티오우레탄계 광학재료를 제조하는 방법과 이를 위한 수지 조성물 및 제조된 광학재료에 관한 것이다. 본 발명에서는, 종래의 문제점인 렌즈 케스팅시 점착테이프에서 점착제가 용출되어 발생하는 백화를 해결하기 위해서, 제조공정에서 얻은 폴리티올화합물을 pH 3.1~7으로 조절함으로써, 반응속도를 증가시켜 렌즈의 가장자리에 백화가 없고, 중합불균형이 없는 티오우레탄계 광학재료를 제공한다.
