摘要:
 用三乙氧基硅烷和丙烯酸正丁酯与缩合单宁和糠醇共缩聚制备一款高硬度、抗压、切割性好的热固性树脂基砂轮切割片来替代酚醛树脂砂轮切割片。通过扫描电子显微镜（SEM）对切割片的外观进行分析，通过万能力学试验机和电动角磨机对砂轮片的硬度、压缩强度和切割性能进行综合评价，采用电喷雾质谱（ESI-MS）对其结构进行定性分析。结果表明，在酸性条件下，三乙氧基硅烷和丙烯酸正丁酯与单宁和糠醇发生了不同程度的共缩聚反应，所制备的砂轮片表面平滑、孔隙少，固化后砂轮切割片的硬度和抗压强度值分别达到了13.56 daN·mm-2和159 MPa，且具有较好的切割性能，切割金属5 s后的质量损失低于自制酚醛树脂基砂轮片。
Abstract:
 Co-condensation of triethoxysilane and n-butyl acrylate with condensed tannin and furfuryl alcohol was used to prepare a thermosetting resin-based cutting disc with high hardness,compression resistance and good cutting ability to replace the phenolic resin cutting disc.The appearance of the cutting disc was analyzed by scanning electron microscope (SEM),the hardness,compressive strength and cutting performance of the grinding wheel were comprehensively evaluated by universal testing machine and electric angle grinder,and the structure was qualitatively analyzed by electrospray mass spectrometry (ESI-MS).The results showed that under acidic conditions,triethoxysilane and n-butyl acrylate underwent different degrees of copolycondensation with tannin and furfuryl alcohol.The prepared grinding wheel had a smooth surface with few pores,and the hardness of the cutting wheel after curing and the compressive strength values reached 13.56 daN·mm-2 and 159 MPa,respectively.The wheel had good cutting performance.The mass loss after cutting metal for 5 seconds was lower than the self-made phenolic resin-based grinding wheel.
