The invention belongs to the technical field of accelerators, and particularly relates to an unsaturated polyester resin accelerator as well as a preparation method and application thereof. The unsaturated polyester resin accelerant is prepared from the following raw materials in percentage by mass: 69 to 89.5 percent of methanol, 0.5 to 1 percent of copper acetate, 5 to 10 percent of cobalt iso-octoate and 5 to 20 percent of water. The invention also provides a preparation method of the unsaturated polyester resin accelerator, which comprises the following steps: mixing methanol, copper acetate, cobalt iso-octoate and water, and stirring for 30-60 minutes to obtain the unsaturated polyester resin accelerator. The accelerator product system is stable, the layering phenomenon cannot occur after long-time standing, and the problem of layering of an existing accelerator system is solved. A resin product prepared from the accelerator is good in curing effect and high in hardness, and the phenomenon that the resin is sticky to hands and becomes soft is avoided. The unsaturated polyester resin accelerator can shorten the gelling time and improve the production efficiency, the highest exothermic peak temperature in the resin curing process is similar to that of commercially available products, the curing effect is ideal, and the unsaturated polyester resin accelerator can replace existing products.
