摘　　要：本文以环氧树脂E12,E51为有机树脂基体,以4-羟丁基乙烯基醚(HBVE)为改性单体,阳离子固化剂,制备HJT光伏太阳能浆料固化结构,通过傅立叶变换红外光谱(FT-IR)表征揭示HBVE开键与环氧树脂共聚后其醚键由烯醚转变为烷醚的作用机制,共聚物玻璃化转变温度通过差示扫描量热(DSC)表征揭示HBVE和E12/E51之间双键与环氧环共聚交联反应的作用机理,同时,对不同含量HBVE改性有机树脂共聚物的力学性能和电性能影响因素进行了阐述。最终,对浆料细度与制备工艺中配料、分散搅拌、三辊研磨、过滤、二次搅拌等工序环节影响因素进行了分析,并就HJT浆料细度对其接触电阻的影响作用机理进行揭示。This article uses epoxy resins E12 and E51 as the organic resin matrix,4-hydroxybutyl vinyl ether(HBVE)as the modified monomer,and cationic curing agent to prepare the cured structure of HJT photovoltaic solar slurry.The Fourier transform infrared spectroscopy(FT-IR)characterization reveals the mechanism of the ether bond transformation from vinyl ether to alkyl ether after HBVE bond opening and epoxy resin copolymerization.The glass transition temperature of the copolymer is character ized by differential scanning calorimetry(DSC)to reveal the mechanism of the double bond and epoxy ring copolymerization crosslinking reaction between HBVE and E12/E51.At the same time,the influencing factors of mechanical and electrical properties of HBVE modified organic resin copolymers with different contents are elaborated.Finally,the factors affecting the slurry fineness and the preparation process,including batching,dispersion stirring,three roll grinding,filtration,and secondary stirring are analyzed.The influence mechanism of HJT slurry fineness on its contact resistance is also revealed.
