Title (EN) RESIN COMPOSITION FOR EPOXY ACRYLIC MEDIUM-REFRACTIVE-INDEX OPTICAL LENS, AND PREPARATION METHOD THEREFOR
(FR) COMPOSITION DE RÉSINE POUR LENTILLE OPTIQUE ACRYLIQUE ÉPOXY À INDICE DE RÉFRACTION MOYEN, ET SON PROCÉDÉ DE PRÉPARATION
(KO) 에폭시 아크릴계 중굴절 광학렌즈용 수지 조성물 및 그 제조방법
Abstract:
(EN) The present invention relates to an epoxy acrylic optical lens and, specifically, to: a resin composition for a high quality epoxy acrylic medium-refractive-index optical lens having a solid phase refractive index of 1.53-1.58, the composition having excellent thermal stability, light resistance, transparency, color, demoldability and compressive strength; and a preparation method therefor. The present invention provides a resin composition for an epoxy acrylic medium-refractive-index optical lens having a solid phase refractive index of 1.53-1.58, the composition comprising: 50-70 wt% of a bisphenol A epoxy acrylate having a hydrolyzable chlorine amount of 0.01-0.11 wt%; 21-45 wt% of methyl methacrylate; and 1-17 wt% of a reactive diluents. According to the present invention, the resin composition for an epoxy acrylic medium-refractive-index optical lens, having good thermal stability, light resistance, transparency, color and demoldability while improving compressive strength in a medium-refractive-index lens having a refractive index of 1.53-1.58 can be obtained by controlling the hydrolyzable chlorine amount of bisphenol A diglycidyl ether to be 0.11 wt% or less and adding a large quantity of MMA to the composition. The epoxy acrylic medium-refractive-index optical lens, according to the present invention, can be widely used in various fields by replacing conventional medium-refractive-index optical lenses.
(FR) La présente invention concerne une lentille optique acrylique époxy et, en particulier : une composition de résine pour une lentille optique acrylique époxy à indice de réfraction moyen ayant un indice de réfraction en phase solide de 1,53 à 1,58, la composition ayant une excellente stabilité thermique, résistance à la lumière, à la transparence, à la couleur, à la démoulabilité et une résistance à la compression, ainsi que son procédé de préparation. La présente invention concerne une composition de résine pour une lentille optique acrylique époxy à indice de réfraction moyen ayant un indice de réfraction à l'état solide de 1,53 à 1,58, la composition contenant : de 50 à 70 % en poids de bisphénol A époxy acrylate ayant une teneur en chlore hydrolysable comprise entre 0,01 et 0,11 % en poids ; de 21 à 45 % en poids de méthacrylate de méthyle ; et de 1 à 17 % en poids de diluants réactifs. Selon la présente invention, la composition de résine pour une lentille optique acrylique époxy à indice de réfraction moyen ayant une bonne stabilité thermique, une résistance à la lumière, à la transparence, à la couleur et à la démoulabilité tout en améliorant la résistance à la compression dans la lentille à indice de réfraction moyen ayant un indice de réfraction de 1,53 à 1,58 peut être obtenue par la régulation de la teneur en chlore hydrolysable dans un éther diglycidylique de bisphénol A entre 0,11 % en poids ou moins et en ajoutant une grande quantité de MMA dans la composition. La lentille optique acrylique époxy à indice de réfraction moyen selon la présente invention peut être largement utilisée dans divers domaines en remplacement des lentilles optiques à indice de réfraction moyen classiques.
(KO) 본 발명은 에폭시 아크릴계 광학렌즈에 관한 것으로, 특히 고상 굴절률 1.53~1.58의 열안정성, 내광성, 투명성, 색상, 탈형성 및 압축강도가 우수한 고품질의 에폭시 아크릴계 중굴절 광학렌즈용 수지 조성물 및 그 제조방법에 관한 것이다. 본 발명에서는, 가수분해성 염소의 함량이 0.01~0.11중량%인 비스페놀 A 에폭시아크릴레이트 50~70중량%와, 메틸메타크릴레이트 21~45중량%와, 반응성 희석제 1~17중량%를 포함하는, 고상 굴절률 1.53~1.58의 에폭시 아크릴계 중굴절 광학렌즈용 수지 조성물이 제공된다. 본 발명에 따르면, 비스페놀 A 디글리시딜 에테르의 가수분해성 염소의 함량을 0.11중량% 이하로 제어하고 조성물 중에 MMA를 다량 함유시킴으로써 굴절률 1.53~1.58의 중굴절 렌즈에서 압축강도를 향상시키면서 열안정성·내광성, 투명성, 색상, 탈형성이 좋은 에폭시 아크릴계 중굴절 광학렌즈용 수지 조성물을 얻을 수 있다. 본 발명에 따른 에폭시 아크릴계 중굴절 광학렌즈는 기존의 중굴절 광학렌즈를 대체하여 다양한 분야에서 널리 이용될 수 있다.
