Title (EN) BIODEGRADABLE FOAM COMPOSITION FOR AN INSOLE USING POLYLACTIC ACID, AND METHOD FOR PREPARING SAME
(FR) COMPOSITION DE MOUSSE BIODÉGRADABLE POUR SEMELLE CONTENANT DE L'ACIDE POLYLACTIQUE, ET SON PROCÉDÉ DE PRÉPARATION
(KO) 폴리락틱엑시드를 이용한 신발 중창용 생분해성 발포체 조성물 및 이의 제조방법
Abstract: front page image
(EN)The present invention relates to a biodegradable foam composition for an insole using polylactic acid and to a method for preparing same in which a large amount of polylactic acid is mixed with a mixing base that includes polylactic acid as a biodegradable resin and a copolymer mixture. Since the mixing base includes a large amount of the polylactic acid as the biodegradable resin, the foam thus obtained may exhibit high biodegradability. In addition, since the copolymer mixture of an ethylene vinyl acetate copolymer, a styrene isoprene styrene copolymer, and an ethylene methyl acrylic acid copolymer are used for preparing the composition, the foam thus obtained may have good durability and high hardness. The foam may be advantageously used as a material for manufacturing an insole.
(FR)Cette invention concerne une composition de mousse biodégradable pour semelle contenant de l'acide polylactique et son procédé de préparation, ledit procédé de préparation consistant à incorporer une grande quantité d'acide polylactique dans une base de mélange qui contient l'acide polylactique à titre de résine biodégradable et un mélange de copolymères. Comme la base de mélange contient une grande quantité d'acide polylactique à titre de résine biodégradable, la mousse ainsi obtenue peut manifester une forte biodégradabilité. De plus, comme le mélange de copolymères constitué d'un copolymère d'éthylène-acétate de vinyle, d'un copolymère de styrène-isoprène-styrène, et d'un copolymère d'éthylène-acide méthylacrylique est utilisé pour préparer la composition, la mousse ainsi obtenue peut avoir une bonne longévité et une dureté élevée. Elle peut être utilisée de manière avantageuse comme matériau pour fabriquer une semelle.
(KO)본 발명은 생분해성 수지인 폴리락틱엑시드 및 공중합체 혼합물로 이루어진 혼합 기재에 다량의 폴리락틱엑시드를 혼합한 것을 특징으로 하는 폴리락틱엑시드를 이용한 신발 중창용 생분해성 발포체 조성물 및 이의 제조방법에 관한 것으로, 상기 혼합기재 내에 다량의 생분해성 수지인 폴리락틱엑시드를 혼합함으로써, 생분해도가 높고, 또한 에틸렌비닐아세테이트 공중합체, 스타이렌이소프렌스타이렌 공중합체 및 에틸렌메틸아크릴엑시드 공중합체의 혼합물을 사용함으로써, 내구성과 경도가 우수하여 신발 중창용 소재에 적합한 것이 장점이다.
