Production method of PVC crosslinking accelerant

The invention discloses a production method of a PVC crosslinking accelerant. The production method comprises the following steps: adding isocyanurate into a reaction kettle, controlling the temperature of the interior of the reaction kettle to be within 20 DEG C by using water, stirring for 3 hours (selecting the reaction kettle with an interlayer, putting the reaction material in the inner partof a kettle body, introducing water into the interlayer of the reaction kettle, controlling the water temperature to further control the reaction temperature of the raw material in the reaction kettle); then adding butyl acetate into the reaction kettle, controlling the temperature of the interior of the reaction kettle to be within 20 DEG C, stirring for 9 hours; adding ethyl acetate into the reaction kettle, controlling the temperature of the interior of the reaction kettle to be within 20 DEG C, and stirring for 6 hours; adding dimethyl carbonate into the reaction kettle, controlling the temperature of the interior
