Abstract

본 발명은 요소와 포름알데히드를 축합시켜서 얻은 열경화성 합성수지인 요소수지를 주성분으로 하되 요소와 포름알데히드 축합시 미반응상태로 남아 있는 유리포름알데히드를 접착제 원료로 사용되는 멜라민과 반응시켜 안정성이 있는 화합물로 합성하므로서 악취발생이 없고 안전성이 우수하게 함을 특징으로 하는 요소수지계 목재접착제 및 이의 제조방법에 관한 것으로, 악취발생이 없고 안전성이 우수하며, 환경오염을 유발하지 않으면서도 접착성이 우수하여 합판, MDF 가구공업의 활성화를 가져올 수 있을 뿐만 아니라 노동생산성 향상과 원가 절감의 효과를 가져올 수 있으며 가구, 건축물속에 살고 있는 우리들로서는 알게 모르게 유해성 물질로 인하여 피해를 보고 있었으나 유해성 물질이 완전히 제거된 접착제를 사용하므로서 국민 위생보건에도 크게 기여할 수 있는 것이다.The present invention is composed of urea resin, a thermosetting synthetic resin obtained by condensing urea and formaldehyde as a main component, but the glass formaldehyde remaining unreacted during condensation of urea and formaldehyde as a compound having stability by reacting with melamine used as an adhesive raw material. The present invention relates to a urea resin-based wood adhesive and a method for manufacturing the same, which are characterized by no odor and excellent safety by synthesizing. Plywood, Not only can the MDF furniture industry be revitalized, but it can also improve labor productivity and reduce costs, and we are suffering from harmful substances without knowing that we live in furniture and buildings. National hygiene bulletin It can contribute greatly to the case.
