本研究的主要目的提供一個被動元件高分子承載帶以取代傳統紙帶抗拉強度的不足及不易回收的問題。研究以聚烯類高分子(例如,LDPE,HDPE)、馬來酸酐接枝聚烯類高分子或是經過交聯的聚烯物,與偶合處理之碳酸鈣、EVA 進行熔融混煉,在混煉過程中添加抗氧化劑避免混煉過程產生大量氧化破壞物性。
在不同CaCO3 /EVA/ Polyolefin 高分子的比率下,製造一混合物使其具有一個白色外觀,韌性強且具有類似於紙帶的低回彈性。並將這些不同比例的混合物製作厚度為0.6mm 試片以量測其抗拉的機械特性。
添加不同比例的碳酸鈣的測試結果顯示,抗拉強度以及伸長率隨著碳酸鈣含量的增加而下降。另一方面,抗拉強度隨著添加HDPE、馬來酸酐接枝HDPE或交聯處理LDPE 的增加而上升。伸長率則只隨HDPE 的增加而下降達到預期效果。另外,所有混合物都具有較好的韌性,因為添加了少量的EVA 分散在混合物內可提供韌性及低變形量的效果。
The primary purpose of this study is to provide a manufacturing process for a
polymer carrier tape for a passive device to sol problems of insufficient strength and recycling with the conventional paper carrier tape. To achieve the purpose, polymer of polyolefin (e.g., LDPE, HDPE), maleic anhydride grafted polyolefin or cross-linked polyolefin blended with calcium carbonate, ethylene-vinyl acetate (EVA) and traces of anti-oxidant in a polymer compounding process to produce an admixture to replace conventional paper carrier tape. The experiment executes a primary compounding process using CaCO3/EVA/ polyolefin polymer in different ratios to manufacture the admixture having a white appearance, flexibility, and low rebound that are similar to a
paper tape. The tensile mechanical properties of the specimens with thickness of 0.6 mm from these composites were measured the effect of the different ratios on the properties of these composites. In the different CaCO3 contents results, it showed that the addition of the CaCO3 provoked a decrease on the tensile strength and elongation of composites. On the other hand, the tensile strength increased with increasing weight fraction of the HDPE, MA-g-HDPE and cross-linked LDPE. The elongation of blends only decreased with increasing weight fraction of the HDPE. All of the blends have better flexibility, because small amount of EVA dispersed in the matrix could provide flexibility and low deformation.
