【摘要】：丙烯酸樹脂是一類分子中含有不飽和雙鍵的丙烯酸酯類單體通過共聚而成的樹脂,由于合成丙烯酸樹脂的單體性質(zhì)活潑且所含取代基多樣,使得丙烯酸樹脂具有優(yōu)異的光澤度、耐候性及穩(wěn)定性能,被廣泛應用于電子材料、膠黏劑、光學材料、生物醫(yī)藥材料等領域。本論文針對印制電路領域?qū)鹣噼偳读系奶厥庑砸?圍繞室溫固化雙組份丙烯酸樹脂及其復合材料的制備、以及丙烯酸樹脂在金相檢測領域的應用開展研究。自由基聚合是制備丙烯酸樹脂的方法之一,其中各聚合單體之間的配比、聚合條件等對所制備的樹脂性能具有重要影響。在甲基丙烯酸甲酯(MMA)和甲基丙烯酸縮水甘油酯(GMA)作為組分A的共聚單體、過氧化苯甲酰(BPO)/N,N-二甲基對甲苯胺(DMT)作為氧化-還原引發(fā)體系的反應中,采用紅外光譜分析、差示掃描量熱分析等手段,對樹脂的固化時間、體積收縮率、熱穩(wěn)定性等展開研究。結(jié)果表明,當組分A中GMA含量為0.25,BPO/DMT=5時,樹脂固化后性能最佳。添加無機填料可改進樹脂的應用性能。針對丙烯酸樹脂應用于金相檢測方面的特點與要求,以前期獲得的樹脂作為基體,選擇納米SiO2、納米TiO2和納米CaCO3,獲得經(jīng)硅烷偶聯(lián)劑改性過后的填料,研究無機填料形貌、添加比例、基本物理化學特性等對丙烯酸樹脂性能的影響與規(guī)律,并獲得了SiO2/丙烯酸樹脂、TiO2/丙烯酸樹脂、CaCO3/丙烯酸樹脂等復合材料。復合材料的SEM、DSC和力學性能測試等結(jié)果表明,三種填料均能均勻分散于丙烯酸樹脂聚合物介質(zhì)中,且復合材料的力學性能也有很大程度提升。當組分A中TiO2、SiO2、CaCO3的含量分別為0.1wt%、0.2wt%、0.5wt%時,所制得的復合材料的拉伸強度、彎曲強度和粘結(jié)剪切強度最大,分別提升81.52%、56.67%、52.87%。金相檢測鑲嵌料是印制電路金相檢測技術中的必需材料之一。透明性、固化時間、加工性能等是其重要的應用參數(shù)。通過與西鐵樹脂和牙托粉樹脂對比研究,采用接觸角測定、金相檢測等手段表征,結(jié)果表明,新開發(fā)的丙烯酸樹脂鑲嵌料外觀透明,能夠?qū)鹣嘣嚇映浞譂櫇窈桶?磨拋和拋光后剖面平整、光滑、肉眼觀察色澤明亮,具有鏡面反射效果,樹脂與銅線界面清晰,未出現(xiàn)分層現(xiàn)象,達到金相試樣檢測效果。
[Abstract]:Acrylic resin is a kind of acrylic resin which contains unsaturated double bond. The acrylic resin has excellent glossiness due to its active monomer properties and various substituents. Weather resistance and stability are widely used in electronic materials, adhesives, optical materials, biomedical materials and other fields. In this paper, the preparation of two-component acrylic resin and its composite materials and the application of acrylic resin in metallographic testing are studied in accordance with the particularity of metallographic inlay in the field of printed circuit. Free radical polymerization is one of the methods for preparing acrylic resin. In the reaction of methyl methacrylate (MMA) and glycidyl methacrylate (GMA) as comonomer of component A and benzoyl peroxide (BPO) / N) -dimethyl-p-methylaniline (DMT) as the redox initiator system, IR spectra were used. The curing time, volume shrinkage and thermal stability of resin were studied by differential scanning calorimetry. The results show that when the content of GMA in component A is 0.25 BPO / DMT = 5, the properties of the resin are the best after curing. The application property of resin can be improved by adding inorganic filler. In view of the characteristics and requirements of acrylic resin used in metallographic examination, nano-SiO _ 2, nanometer TiO2 and nano-CaCO _ 3 were selected as matrix, and the morphology of inorganic fillers was studied after modified by silane coupling agent. The effect and regularity of adding ratio, basic physical and chemical properties on the properties of acrylic resin were studied. The composite materials such as SiO2/ acrylic resin TiO2 / acrylic resin CaCO3 / acrylic resin were obtained. The results of SEM DSC and mechanical properties test show that the three fillers can be uniformly dispersed in the acrylic resin polymer media and the mechanical properties of the composites are improved to a large extent. When the content of TiO2SiO2CaCO3 in component A is 0.1 wt%, the tensile strength, flexural strength and bond shear strength of the composites are the highest, and the tensile strength, flexural strength and bond shear strength of the composites are 81.52and 56.67%, respectively. Metallographic testing inlay is one of the necessary materials in printed circuit metallographic inspection technology. Transparency, curing time and processing performance are important application parameters. Compared with iron resin and denture powder resin, it was characterized by contact angle measurement and metallographic examination. The results showed that the newly developed acrylic resin inlay was transparent in appearance and could fully wetting and wrapping metallographic samples. After polishing and polishing, the profile is smooth and smooth, the naked eye has bright color, mirror reflection effect, the interface between resin and copper wire is clear, there is no delamination, and the detection effect of metallographic sample is achieved.
