| 摘要: | 本文討論丙烯腈-丁二烯-苯乙烯樹脂（ABS）和加工過程中所形成的奈米二氧化鈦複合材料，物理性質，機械性質和熱性質。實驗用3-甲基丙烯酸基丙基三甲氧基矽烷（MPS）和四乙氧基矽烷（TEOS）改質奈米二氧化鈦。混合ABS樹脂/奈米二氧化鈦（包括未改質和改質）奈米複合材料的製備與不同的重量百分比奈米二氧化鈦混合。
探討不同重量百分比ABS樹脂/奈米二氧化鈦的形態學( FT-IR、XRD、粒徑分析、SEM、TEM、ESCA )，物理性質( 密度，空孔率，接觸角 )，機械性質( 硬度，抗折試驗，抗張試驗，衝擊強度試驗，耐磨耗指數，DMA ) ，熱性質(TGA、MI、HDT、Vicat、DSC )，ABS樹脂性能和完善的差異程度。
實驗結果得知，經由FT-IR與ESCA測試，發現ABS/奈米氧化鈦奈米複合材料的改質後官能基，粒徑分析中奈米氧化鈦（未改質和改質）都在奈米規範；在XRD測試可以看到晶相結構；在FE-SEM和TEM具有的良好分散性能。
添加奈米二氧化鈦的物理性質的測試，有效提升；在機械性質測試結果，拉力、抗張、硬度和耐磨耗，有效提升4%以上，耐衝擊有下降20%以上；在熱性質，耐熱性提高效果更加顯著的增加10℃以上。
This paper aime to discuss the Acrylonitrile-Butadiene-Styrene (ABS) resin and nano titanium oxide composites formed by the processing process, physical properties, mechanical and thermal properties of . The research used 3-methacryloxy-propyl-trimethoxysilane (MPS) and Tetraethyl orthosilicate (TEOS) to modify surface of nano titanium oxide . Prepared by mixing ABS resin/nano titanium oxide (include non-modify and modify) nano composites with different content when mixing weight percent of nano titanium oxide by mixing.
After forming the different levels of weight percent of the ABS resin/nano titanium oxide morphology (FT-IR, Particle, XRD, FE-SEM, TEM, ESCA), physical properties (Density, Contact Angle , Void content), mechanical properties (Hardness, Flexural test, Tensile test, Impact strength, Wearing), thermal properties (TGA, MI, HDT, Vicat, DSC) for ABS resin properties and improve the degree of difference.
Experimental results show, by FT-IR, the crystal structure of ABS / nano titanium oxide nano composites was determined; in particle size analysis show nano titanium oxide (include non-modify and modify) are both in nano specification; at XRD and ESCA test can see nano composites contains nano titanium oxide; Good dispersion can be seen in FE-SEM and TEM.
Adding nano titanium oxide powder does effectively enhance in the physical properties test; In the mechanical properties test results showed that the tensile and flexural, hardness and wearing index decreased are effectively enhance, and impact decreased. In the thermal properties, heat resistance to enhance effect even more pronounced with the increase of nano titanium oxide added. |
