Abstract: front page image
(EN)The present invention relates to a thermoplastic polyurethane resin composition, having excellent scuff resistance and rebound resilience, for manufacturing a golf ball, and to a method for preparing the same. The composition contains 30 to 70 wt% of polyol having a hydroxyl value within a range of 11.22 to 224.11 ㎎KOH/g; 15 to 60 wt% of isocyanate essentially including paraphenylene diisocyanate; 5 to 40 wt% of a chain extending agent; and 0.1 to 1 wt% of peroxide.
(FR)La présente invention concerne une composition de résine de polyuréthane thermoplastique présentant d'excellentes propriétés de résistance à l'abrasion et d'élasticité de rebondissement destinée à la production d'une balle de golf, et son procédé de préparation. La composition contient de 30 à 70 % en poids d'un polyol ayant un indice d'hydroxyle qui s'inscrit dans la plage allant de 11,22 à 224,11 mg de KOH/g ; de 15 à 60 % en poids d'isocyanate comprenant essentiellement un diisocyanate de paraphénylène ; de 5 à 40 % en poids d'un agent d'extension de chaîne ; et de 0,1 à 1 % en poids de peroxyde.
(KO)본 발명은 스커프 저항성과 반발탄성이 우수한 골프공 제조용 열가소성 폴리우레탄 수지 조성물 및 그 제조방법에 관한 것으로서, 11.22 내지 224.11㎎KOH/g의 범위 이내의 히드록실값을 갖는 폴리올 30 내지 70중량%; 파라페닐렌디이소시아네이트를 필수로 포함하는 이소시아네이트 15 내지 60중량%; 쇄연장제 5 내지 40중량%; 및 과산화물 0.1 내지 1중량%;를 포함하여 이루어짐을 특징으로 한다.
