Abstract
가. 청구범위에 기재된 발명이 속한 기술분야.end. The technical field to which the invention described in the claims belongs.
발포형 폴리우레탄 포장재의 생산방법.Method of producing foamed polyurethane packaging.
나. 발명이 해결하려고 하는 기술적 과제.I. The technical problem that the invention is trying to solve.
본 발명은 폴리올과 MDI를 공중합시켜서 발포성 폴리우레판 포장재를 제조하는 방법과 장치에 관한 최적조건을 개발한 것으로 본 발명은 기존의 포장재인 스티폴에 비하여 경제성과 양산성이 좋으면서 2차 공해발생을 일으키지 않는 안정성을 보유토록 하여 각종 포장재를 안정적으로 공급할 수 있도록한데 요지가 있음.The present invention has been developed an optimal condition for manufacturing a foamed polyurethane packaging material by copolymerizing a polyol and MDI, the present invention is economical and mass-produced compared to the conventional packaging material stypol and secondary pollution generation The main purpose of this is to provide various packaging materials stably by maintaining stability that does not cause any damage.
다. 발명의 해결방법의 요지All. Summary of Solution of the Invention
발포성 우레판 포장재를 제조함에 있어서, 폴리올과 MDI의 혼합비를 폴리올 0.95~1.15범위, MDI 1~1.25범위로 하고 이들의 반응 온도 조건은 38℃~47℃의 범위로 하여 압력조건은 양자 공히 1차로 3-6kg/㎠, 2차로 6-12kg/㎠로 반응시킴을 특징으로 한 것이다.In preparing the foamed urethane packaging material, the mixing ratio of polyol and MDI is in the range of 0.95 to 1.15 in polyol and in the range of MDI in 1 to 1.25, and their reaction temperature is in the range of 38 ° C to 47 ° C. It is characterized in that the reaction at 3-6kg / ㎠, 6-12kg / ㎠ second.
라. 발명의 중요 한 용도.la. Important use of the invention.
각종 공산품의 포장재.Packaging materials for various industrial products.
