摘　　要：研制的产品典型配方(质量份)是苯酚-淀粉树脂∶六次甲基四胺∶木粉∶碳酸钙∶氧化镁∶硬脂酸锌∶硬脂酸∶油溶苯胺黑∶群青=37.0∶6.4∶48.0∶6.0∶0.6∶0.6∶0.4∶0.5∶0.5;制备工艺参数是混合时间≥60min,工作辊温度85-95℃,空转辊温度145-155℃,辊距2.3～2.5mm,热炼时间4～5min,拼批时间≥45min;模塑工艺参数是预热温度100～110℃,预热时间10～15min,模塑压力≥25MPa,模塑温度175～180℃,模塑时间0.8～1.0min/mm,排气≥3次。产品性能达到酚醛模塑料(PF2A1)国家标准或优良,原料成本比苯酚-甲醛模塑料(PF2A1)低20.4％。A new versatile phenol-starch material was developed. The mass percentage of the constituent was 37. 0% phenol-starch resin, 6.4% hexamethylene-tetramine, 48.0% wood flour, 6.0% calcium carbonate, 0. 6% magnesium oxide, 0. 6% zinc stearate, 0. 4% stearic acid, 0. 5% oil aniline black, 0. 5% ultramarine. During the preparation, the mixing time was longer than 60min;The temperature of the working roller was 85-95℃; The temperature of the idle roller was 145-155℃; The distance of the two rollers was 2.3-2.5mm; The warm-up time was 4-5min and the combining batch time was longer than 45min. When the materials were moulded, the preheating temperature was 100-110℃; The preheating time was 10-15℃; The moulding pressure was larger than 25MPa; The final moulding temperature was 175-180℃; The final moulding time was 0.8-1.0min/mm and the exhausting times were more than 3 times. The properties of the product meet the national standard of phenolic moulding material (PF2A1) . Compared with the phenol-formaldehyde moulding materials (PF2A1) ,the product has 20. 4% less raw material cost and more competitive.
