摘要:
 采用木质素替代部分苯酚制备热固性低成本木质素-酚醛树脂基砂轮片（LPFG）替代商业酚醛树脂基砂轮片（PFG）。通过万能力学试验机和电动角磨机对砂轮片的布氏硬度、抗压强度和切割性能进行测试；通过扫描电子显微镜（SEM）对砂轮片的外貌进行观测；通过差示扫描量热法（DSC）分析手段对木质素-酚醛树脂（LPF）与酚醛树脂（PF）进行固化分析。结果表明，在碱性条件下，木质素替代30%苯酚制备LPFG表面光滑，与商业PFG相比具有较高的布氏硬度和抗压强度，同时LPFG的切割性能接近商业PFG，且木质素的加入降低了PF树脂的固化温度。
Abstract:
 To replace the commercial phenol-formaldehyde resin based grinding wheel (PFG),a thermosetting low-cost grinding wheel based on lignin-phenol-formaldehyde resin (LPFG) was prepared with lignin as the replacement for parts of phenol.The universal testing machine and electric angle grinder were used to study the Bribell hardness,compression strength and cutting property of LPFG.Meanwhile,the appearance of LPFG was observed by the scanning electron microscope (SEM) and the curing property of lignin-phenol-formaldehyde (LPF) resin was researched by the curve of differential scanning calorimetry (DSC).The results indicated that the LPFG prepared with 30% replacement rate of lignin under alkaline condition had a smooth appearance,its Brinell hardness and compression strength were higher than that of commercial PFG.Moreover,the cutting property of LPFG was similar with commercial PFG and the curing temperature of LPF resin was lower than that of PF resin.
