Abstract
The invention relates to the technical field of coating, in particular to a roller type spaced coating method and equipment. The coating method comprises the following steps: a thin film material with stretch resisting strength is cut into spaced templates; the spaced templates cover a coating roller; in the coating process, thin film areas on the spaced templates are positioned between the coating roller and a material to be coated; the material cannot be coated with liquid coating in the thin film areas, and the material is only coated with the liquid coating in blank spaces, so that the spaced coating is realized; meanwhile, the thin film areas respectively make contact with the surfaces of the coating roller and the surfaces of the material, so that the blank spaces are filled with the liquid coating; and at the same time, the thickness of a coating layer formed by the liquid coating is identical with that of a thin film. Therefore, according to the coating method disclosed by the invention, the control over the thickness of the coating layer can be realized, and further ultrathin coating is realized.
