Fine stain-resistant antibacterial brick and preparation method thereof

The invention discloses a fine stain-resistant antibacterial brick and a preparation method thereof. The antibacterial brick sequentially comprises a green body, a ground glaze layer, a high-temperature matte glaze layer, a printing layer and an antibacterial glaze layer from bottom to top, glaze slip of the antibacterial glaze layer is formed by mixing an antibacterial agent and skin glaze slip; the antibacterial agent is composed of nano-zinc oxide and a silver iodide complex. The antibacterial brick has a remarkable antibacterial effect and can meet the antibacterial requirements of consumers; the brick surface feels fine and smooth and effectively prevents fouling; by applying the antibacterial glaze, ink-jet color development is better combined with a glaze body, the texture is softer, a matte ceramic tile obtained without polishing after firing has a soft polishing effect and high glossiness, a bright ceramic tile is obtained after polishing, and the matte ceramic tile and the bright ceramic tile are bo
