초록
소나무 크라프트 펄프제조과정중 회수된 폐액으로 Black liquor-phenol formaldehyde. Methylolated kraft lignin-phenol formaldehyde 및 Lignin cake-phenol rein 세 종류의 접착제가 제조되었다. Black liquor-phenol formaldehyde resin 제조시 Phenol의 약 60%를 크라프트 폐액으로 대치할 수 있다. 본 접착제의 최적압착조건은
A kraft black liquor obtained from pulping of pine (Pinus densiflora Sieb et Zucc) was used for producing three kinds of adhesive such as black liquor-phenol formaldehyde resin, methyloeated kraft lignin-phenol formaldehyde resin, and lignin cake-phenol resin. In case of producing black liquor-phenol formaldehyde resin, about 60 percent of the phenolic resin could be replaced by black liquor. Also the optimal press condition appeared to be
