Abstract: A thermochromic floor mat is provided, which includes a floor mat body. The floor mat body is composed of PTE film, printing layer, OPP film, temperature sensing ink layer, PVC film, and injection molding layer from top to bottom. The temperature sensing ink layer forms a plurality of thermochromic patterns at a bottom of the OPP film. The OPP film is a transparent film, suction cups are connected to the injection molding layer. And a production process for thermochromic floor mat is provided, which includes preparing a thermochromic printing film, an injection molding raw material, and injection molding. The temperature sensing ink layer is provided in the floor mat, the temperature sensing ink layer is provided with temperature sensitive color powder. The temperature sensing ink layer is provided between the OPP film and the PVC film to prevent the temperature sensing ink layer from falling off after long-term use.
