Abstract

A study has been made on the preparation of liquid resin of non-solvent and non-discoloration type for replacement of the soft PVC at room temperature. A new synthetic process was developed by structure-control design of polyurethane synthesis using pre-polymer and polyols as curing agent. The optimum recipe was made according to macro-glycols, molecular weight and reaction conditions, and the final products indicated that the mechanical properties such as tensile strength, tear strength and flexibility was very excellent than PVC products. Also, viscosity, hardness and color operations of the final products can be controlled by this system. And yellowing property by UV and NOx gas was improved from the various additive experiment.

연질 PVC 대체를 위한 비변색 타입의 무용제형 상온 액상수지를 폴리올을 경화제로 사용하는 폴리우레탄수지 구조제어 설계를 통한 프리폴리머 합성방법을 응용하여 제조할 수 있었다. Macro-glycol, 분자량 및 반응조건의 영향 등을 고찰하여 최적의 작업성과 물성을 가지는 무용제형 상온액상수지를 제조하였으며, 우수한 기계적인 특성과 함께 유색작업을 위한 안료의 분산성 등에서도 우수하였고, Tg가 $-40^{\circ}C$의 값을 나타내었다. 또한 자외선 노출이나 질소산화물에 의한 황변특성도 개선할 수 있었다.
