Abstract

본 발명은 건축자재나 산업자재 등에서 천연 목재 대체품으로 사용되는 구조재용 경질 우레탄 포옴에 관한 것으로, 종래의 경질 우레 X탄 포옴이 비중에 따른 굴곡강도, 압축 강도, 인장강도 등과 같은 기계적 물성이 열등하고, 목재의 섬유성 특징을 나타내기 어려운 문제점을 해결한 것이다.The present invention relates to a rigid urethane foam for structural materials used as a substitute for natural wood in building materials and industrial materials, the conventional rigid urethane foam is inferior in mechanical properties such as bending strength, compressive strength, tensile strength, etc. It solves the problem of hardly showing the fibrous characteristics of wood.

즉, 본 발명은 1차적으로 저분자량의 폴리에테르계 폴리올과 과잉의 이소시아네이트를 반응시켜 NCO%가 15∼28%인 이소시아네이트말단우레탄 프리폴리머를 제조한 후, 이를 다시 폴리에테르계 폴리올과 폴리에스테르계 폴리올로 된 폴리올과 가교제, 촉매, 표면활성제, 발포제 및 난연제 등의 첨가제로 구성된 폴리올 혼합체와 혼합하고 발포 반응시켜 제조된 구조재용 경질 우레탄 포옴에 관한 것으로서, 본 발명에 따라 제조된 경질 우레탄 포옴은 기계적 물성이 증진되고 목재의 섬유성과 같은 성질을 한층 더 지니게 되어 못이나 스크류 작업에서도 깨지거나 부서지지 않기 때문에 구조재로서 천연 목재 대용품으로 사용이 가능하다.That is, in the present invention, a low molecular weight polyether polyol and an excess of isocyanate are first reacted to prepare an isocyanate terminal urethane prepolymer having an NCO% of 15 to 28%, and then again a polyether polyol and a polyester polyol. The present invention relates to a rigid urethane foam for structural materials prepared by mixing and foaming a polyol mixture comprising a polyol and an additive such as a crosslinking agent, a catalyst, a surfactant, a foaming agent, and a flame retardant, wherein the rigid urethane foam prepared according to the present invention has a mechanical property. This enhanced and more fibrous nature of wood makes it possible to use as a substitute for natural wood as a structural material because it does not break or break even in nail or screw work.
