Abstract

본 발명은 아크릴로니트릴이 90중량%이상 포함된 아크릴 중합체 용액을 방사하고 용매를 제거한 후 30∼99℃의 물 및 가압수증기하에서 2단계 이상의 다단연신을 행하며 다단연식중 습윤상태에서 유제처리 및 염기의 수용액 또는 증기로 처리하되 염기의 종류는 트리에틸아민, 암모니아, 수산화나트륨, 수산화칼륨, 암모니아 금속염으로 구성되는 군으로부터 선택된 1종이고 염기의 농도는 0.006mol/ℓ∼0.015mol/ℓ로 처리하여 탄소섬유용 아크릴전구체를 제조하고 이를 통상의 방법으로 건조, 내염화, 열처리 하므로서 탄소섬유 제조시 순간적인 축열로 인한 단시간 융착을 방지하여 섬유가 분해, 절사되는 것을 최소화하므로서 탄소섬유의 품질 및 생산성을 향상시킨 고강도·고탄성 탄소섬유용 아크릴 전구체의 제조방법에 관한 것이다.The present invention spins an acrylic polymer solution containing 90% by weight or more of acrylonitrile, removes a solvent, and performs two or more steps of multistage stretching under water and pressurized steam at 30 to 99 ° C. Treated with an aqueous solution or steam, and the base is selected from the group consisting of triethylamine, ammonia, sodium hydroxide, potassium hydroxide, and ammonia metal salts, and the concentration of the base is treated with 0.006 mol / l to 0.015 mol / l. Carbon fiber acrylic precursor is manufactured and dried, flameproofed, and heat treated in a conventional manner to prevent short time fusion due to instant heat storage during carbon fiber production, thereby minimizing fiber decomposition and cutting, thereby improving the quality and productivity of carbon fiber. It is related with the manufacturing method of the improved acrylic precursor for high strength and high elastic carbon fiber.
