    摘要
  • 摘要: 以马来海松酸酐及聚乙二醇200为原料,ZnO为催化剂,制备得到4种不同酸值的马来海松酸聚乙二醇酯,通过傅里叶红外光谱(FT-IR)对产物的结构进行表征,并考察其对Sn0.7Cu无铅钎料的助焊性能. 结果表明,当马来海松酸酐与聚乙二醇的摩尔量之比为1:0.5,1:1.0,1:1.5及1:2.0时,反应体系的酸值分别在3,4,7和10 h后达到稳定,得到的马来海松酸聚乙二醇酯的酸值分别为212.5,178,125.3,72.7 mg/g;酸值为178 mg/g的马来海松酸聚乙二醇酯对Sn0.7Cu钎料的助焊效果最佳,其在铜基板上形成的焊点饱满,表面光亮,扩展率达到75.8%,优于未经改性的天然松香.
    Abstract: The maleopimaric acid polyethylene glycol ester (MPE) with kinds acid value were prepared by maleopimaric acid anhydride (MPAD) and polyethylene glycol 200 (PEG200) when ZnO was used as catalyst. Final products were characterized by FT-IR and performance of MPE-based fluxes were investigated. The results showed that the acid value of maleopimaric acid polyethylene glycol ester are 212.5, 178, 125.3, 72.7 mg/g when the mole ratio of MPAD and PEG200 are 1:0.5, 1:1.0, 1:1.5, 1:2.0 and the reaction time was 3 h, 4 h, 7 h,10 h in turn. The maleopimaric acid polyethylene glycol ester shows optimal soldering ability when its acid value is 178 mg/g, and the appearance of soldered joints are regularly and shiny, the spreading ratio to Sn0.7Cu is 75.8%, which is higher than unmodified rosin.
