EPDM橡膠應用於塗佈製程中的特性研究與耐藥性改善
Research and Tolerance Improve of the Characteristics EPDM Rubber Application and Coating Process
摘要
EPDM (ethylene propylene diene monomer)橡膠近年來由於發展迅速，進而廣泛的被工業界所應用。亦於其應用的層面不同，所以有不同的成分配比。本篇的研究是增加EPDM第三成份比(ENB)，加強其高分子聚合度，藉此測試其EPDM橡膠是否更具優良的機械性能與耐藥性。 結果顯示，EPDM橡膠外表之機械性能(結構硬度)會與加入第三成份的量成正比，故有著良好的加工特性。於溶劑中的浸泡測試中，EPDM橡膠雖然有膨潤吸收與溶解的效應發生，但此效應大小確會與加入第三成份的量成反比，即意謂著有更佳的耐藥性。在TGA (thermo gravimetric analyzer)分析儀中顯示，EPDM橡膠隨著第三成份的增加，會有更好的耐熱性質表現。 改善過後的材質，在實際上機測試後不僅有著良好的耐藥性表現，更延長了其材料的使用壽命。並於該製程中解決了因為材料表面缺陷，所引起的產品良率損失。

EPDM (ethylene propylene diene monomer) rubber development improved rapidly in recent years, applied widespread in the industry. Because different applications are not similar, therefore there are different ingredient allocations. This research increases the third ingredient of EPDM comparatively (ENB), strengthening its high polymerization degree, then testing whether or not EPDM rubber has fine machine capability and tolerance. The results show, EPDM rubber’s exterior machine capability (structure degree of resistance) will compare with the third ingredient’s strength, and therefore has great processing characteristic. Soaked in the test solvent, though EPDM rubber has the ability to absorb and dissolve the effects, but the effects size will affect the comparison with the third ingredient’s strength, and will have great tolerance. In TGA (thermo gravimetric analyzer) analysis it is shown that, EPDM rubber along with the increase in the third ingredient, will have greater heat resistance performance. The improved material, in actual testing has good performance in terms of tolerance, and lengthened the material’s service life, resolving the defects noted previously in the coating process that cause losses in the product’s efficiency.
