Abstract

In order to improve the usability of glue, a traditional adhesive material, and the gelation process of seaweed extract carrageenan, a liquid adhesive for wood preservation was prepared by mixing the two materials. The prepared wood adhesive was mixed with a 15 wt% aqueous solution of glue, λ-carrageenan, an antibacterial agent, an antifoaming agent, and the maximum adhesive strength of 1.80 Mpa was confirmed. As a result of comparison, the adhesive strength was superior to that of 5 different types of traditional natural adhesive ingredients (aqueous solution) and 1 type of polyvinyl acetate-based adhesive.

전통 접착 소재인 아교의 사용성과 해초 추출물 카라기난의 겔화 현상을 개선하기 위해 두 재료를 혼합하여 목재 보존용 액상형 접착제를 제조하였으며, 9종의 천연 및 합성 접착제와의 물성 비교를 통해 적용 가능성을 확인하였다. 제조한 목재 접착제는 15 wt% 아교 수용액과 λ-carrageenan, 항균제, 소포제 등을 혼합하였으며, 1.80 Mpa의 최대 접착 강도를 확인하였다. 비교 결과 5종의 전통 천연 접착 성분(수용액)과 Polyvinyl acetate 기반 접착제 1종보다 우수한 접착 강도가 나타났으며, 총호기성생성균수와 유해성(TVOC, HCHO, 중금속) 시험 결과 불검출로 항균성과 안정성을 확인하였다.
