Effects of Coupling and Solidified Agents on the Thermal-setting Plastic from Phenolic Resin Impregnated by Coal Gangue
偶联剂与固化剂对煤矸石改性酚醛树脂制热固性塑料的影响

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.
