Beschreibung
Zusammenfassung:	The present invention relates to a composition for suitably delaying a speed of a gelation reaction by using at least two types of complexated cross-linking agent inserted to generate the gelation reaction from the outside in a sol solution comprising cellulose as a polymer compound derived from the nature and a substitution product thereof. The present invention relates to an injection-moldable and gelation delay-type hydrogel composition and a manufacturing method thereof. The injection-moldable and gelation delay-type hydrogel composition comprises a cellulose compound, a hydrophilic polymer, an oily raw material, a dispersing agent, an additive, alcohol, polyol, a neutral salt, an alkali salt, a polyvalent metal salt, and inorganic acid or organic acid. 본 발명은 천연에서 유래된 고분자 화합물인 셀룰로오스 및 그들의 치환체로 이루어진 졸(sol) 용액에 외부로부터 겔화 반응을 일으키기 위해 투입하는 2종류 이상의 복합화된 가교제를 사용함으로써 겔화반응의 속도를 적절히 지연시킬 수 있는 조성물로서, 셀롤로오스 화합물, 친수성 고분자, 유성원료, 분산제, 첨가제, 알코올, 폴리올, 중성염, 알칼리염, 다가 금속염, 및 무기산 또는 유기산을 포함하는 주입 성형이 가능한 겔화 지연형 하이드로겔 조성물 및 이의 제조방법에 관한 것이다.
