초록

입자무기물 충전 복합재료에 있어서 계면의 친화성과 충전재의 분산성을 향상시키기 위하여 고분자 수지로 마이크로캡슬화된 glass beads를 제조하였다. Glass beads의 마이크로 캡슐화에는 상분리법을 이용하였으며, 벽막수지로는 EMAA와 EAA를 사용하였다. 캘슐화 형성상태를 분석하기 위하여 열분석과 SEM을 이용하였다. HDPE에 캡슐화 g1ass beads를 10∼30중량 퍼센트까지 충전시켜 HDPE/마이크로캡슐화 glass beads 복합재를 제조하고 벽막수지종류와 캡슐화 비율에 따른 인장강도, 인장탄성율 및 동역학적 성질의 변화를 측정하였다. 인장강도의 경우 캡슐화 glass beads로 충전시킨 경우 복합재의 인장강도저하가 현저하게 둔화되었으며, 인장탄성율의 경우 캡슐화 glass beads로 충전시킨 경우 30∼40% 정도의 향상된 값을 나타내었다 동역학적 물성측정에 있어서는 계면접착력과 분산성의 향상을 볼 수 있었다. 그러나 벽막수지의 종류에 따른 복합재의 물성 차이는 크지 않음을 알 수 있었다.

To improve the adhesion of interface and dispersion of glass beads in the composite, HDPE filled with glass brads, we encapsulated the g1ass beads with polymer by phase separation method using complex coacervation in organic solvent. EMAA and EAA were used as the polymeric wall materials. The microencapsulation efficiency and morphology were observed by thermogravimetric analysis and SEM, respectively. And also we investigated the physical and dynamic mechanical properties of the composite as the function of the beads contents and microencapsulation efficiency. Compared with the composite containing non-treated glass beads, the decrease in tensile strengthe of the composites containing the encapsulated glass beads become markedly small, and about 30∼40% Increase in tensile modulus was observed. From the results of the dynamic mechanical analysis, it was found that the adhesion of interface and dispersion could be improved upon encapsulation.
