In order to replace the imported alloy puttyresin，an unsaturated polyester resin was synthesized by one-step process，with conventional raw materials，such as propylene glycol，ethylene glycol，diethylene glycol，pentaerythritol，tetrahydrophthalic anhydride，adipic acid，fumaric acid，maleic anhydride，and styrene，increasing the utilization rate of raw materials，reducing the amount of waste water and VOC emissions，achieving a simple operation and short production cycle；the curing system and curing performance werestudiedby preparing the alloy puttyby synergistically changing the resin and curing system synthesizedby changing the amount of raw materials. The solidification temperature of the homemade alloyputty resin was determined by dynamic differential scanning calorimetry（DSC）. Finally，the performance comparison test between the homemade alloy puttyresin and the imported resinshowed that the main technical specification such as adhesion，dryness and sanding aresimilar，which couldcompletely replace the imported resin and reduce the cost of domestic alloy putty.
