摘要: 以廉价的煤矸石为主要原料,加入硅烷类偶联剂KH550、固化剂乌洛托品等改性物质对酚醛树脂进行改性处理,采用热压成形法制备了热固性酚醛模塑板. 对其部分机械性能和物理性能作了检测,发现固化剂的较佳用量为6%,偶联剂较佳用量为1.5%~2.0%,煤矸石中的有机质有利于改善材料性能,灰分较高的煤矸石对材料性能的改善较差. 所制板材除拉伸强度略低于国家标准外,其余所测指标都达到国家标准,说明煤矸石改性酚醛树脂的思路可行. 关键词:煤矸石;酚醛树脂;热固性塑料;改性

Abstract: Mould board based on thermosetting phenolic resin has been made by thermo-mould way, cheap coal gangue and phenolic resin as main raw materials, and other additives, such as coupling and solidified agents, are blended as modified substances of mould board. Some physical and chemical properties of the mould board are studied. The suitable proportion of solidified agents is 6% and that of coupling agents is 1.5%~2.0%. The organic substances in the coal gangue can improve the mechanical properties of the mould board. The higher the ash in the coal gangue is, the less the physical and chemical properties of the mould board can be improved. The values of items of the board reach national standard values except that of tensile strength, so the idea that phenolic resin is modified by coal gangue is feasible.
