氰基丙烯酸乙酯胶粘剂增韧增稠改性

Thickening and toughening modification of ethyl α-cyanoacrylate adhesive

通过加入不同相对分子质量的PMMA、PBMA和PIBMA ,以考察其对α -氰基丙烯酸乙酯拉伸剪切强度、剪切冲击强度和增稠性能的影响。结果表明 ,加入量为 15 %～ 2 0 % ,相对分子质量为 10万的PIBMA作为α 氰基丙烯酸乙酯的增韧增稠改性剂的效果较为显著。

Thickening and toughening modification of ethyl α cyanoacrylate adhesive by blending PMMA?PBMA and PIBMA were studied. The effect of different molecule weight and amount on impact strength of adhesive were investigated. The result showed that the thickness and mechanical properties had been obviously improved by blending 15%～20% PIBMA whose molecule weight was 1.0×10 5.
