Abstract
본 발명은 발포 입자의 기포가 미세 균일한 발포성 폴리올페핀 수지 입자를 제조하는 방법을 제공하며, 이 방법은 분산제를 함유하고 있는 수성 매체 중에 폴리올레핀 수지를 넣는 단계; 상기 폴리 올레핀 수지에 비닐 방향족 단량체를 투입하는 단계; 상기 비닐 방향족 단량체의 투입과 동시에, 또는 투입 직후에 폴리올레핀 왁스 또는 지방산 비스 아미이드를 첨가하여 그라프트 중합시킴으로써 폴리 올레핀계 공중합 수지를 얻는 단계; 상기에서 얻은 폴리 올레핀계 공중합 수지에 발포제를 압입시키는 단계; 및 상기 단계에서 얻은 발포제-합임 공중합 수지를 숙성 공정을 거치지 않고 직접 발포시키는 단계를 포함함을 특징으로 한다. 이러한 방법의 의해서 얻어지는 폴리올레핀 발포 입자는 그의 기포구조가 미세 균일하며, 이를 이용하여 성형한 성형품은 내충격성이 우수하다.The present invention provides a method for producing expandable polyol peffin resin particles having fine uniform bubbles of foam particles, the method comprising the steps of placing the polyolefin resin in an aqueous medium containing a dispersant; Injecting a vinyl aromatic monomer into the polyolefin resin; Obtaining a polyolefin copolymer resin by graft polymerization by adding polyolefin wax or fatty acid bisamide simultaneously with or immediately after addition of the vinyl aromatic monomer; Injecting a blowing agent into the polyolefin-based copolymer resin obtained above; And directly foaming the blowing agent-combination copolymer resin obtained in the step without undergoing a aging process. The polyolefin foamed particles obtained by this method have a fine uniform bubble structure, and the molded article molded using the same has excellent impact resistance.
