The invention discloses a production process of an electric hot plate with the effect of releasing negative ions, and relates to the field of electric hot plate production. The problem that existing electric hot plates only have the heating function is solved. The production process specifically includes the following steps that firstly, tourmaline is modified to obtain modified tourmaline powder;secondly, the modified tourmaline powder, carbon black powder, water, a styrene-acrylic emulsion, tourmaline powder, pottery clay, polytetrafluoroethylene and glycerine are stirred evenly to obtain apaste; thirdly, a heating element is installed on a first insulating layer; fourthly, a second insulating layer is laid outside the heating element; and fifthly, the paste is coated on the surfaces of the first insulating layer and the second insulating layer and then cured and baked to obtain a finished product. According to the production process of the electric hot plate with the effect of releasing the negative ions, the finished product can release a large number of negative ions, air purification and health bodies of users are facilitated, the higher maximum power and surface temperature are achieved, and the heating need of people can be met.
