Abstract

본 발명은 목재로 제조되는 연필을 폴리스틸렌 소재로 대체하므로 목재를 벌목하지않아 나무를 그대로 보존할 수 있을 뿐만아니라, 상기 폴리스틸렌에 생분해성 마스터 배치(MASTER BATCH)의 사용으로 잉여 농산물을 활용하므로 석유자원의 절약효과와, 이로부터 제조되는 연필은 빠른시간내에 폴리스틸렌 소재부분이 생분해 되어 환경을 보호할 수 있게한 생분해 가능한 폴리스틸렌 연필의 제조 방법 및 그 장치에 관한 것으로, 폴리스틸렌의 중합비율 지피-피에스(GP-PS) 50% ∼ 60%, 에이치아이-피에스(HI-PS) 40% ∼ 50% 와 ; 적색안료 0.0005%, 흰색안료 0.003%, 황색안료 0.002%를 배합하여 착색하고; 생분해성 마스터 배치 20%를 믹서기로 혼합한 후, 무기계 발포제 0.5 ∼ 0.7%를 투입하여 제조하는 것이다.The present invention replaces a pencil made of wood with a polystyrene material, thus not only wood can be preserved without logging the wood, but also by using a biodegradable master batch (MASTER BATCH) in the polystyrene, and thus using petroleum resources. And a pencil produced therefrom relates to a method and a device for producing a biodegradable polystyrene pencil which can protect the environment by biodegrading a polystyrene material portion in a short time. The polymerization ratio of polystyrene is GP-PS (GP). -PS) 50% to 60%, HI-PS 40% to 50%; Red pigment 0.0005%, white pigment 0.003%, yellow pigment 0.002% are mixed and colored; After mixing 20% of the biodegradable master batch with a blender, 0.5 to 0.7% of the inorganic foaming agent is added to prepare.
