The invention relates to the technical field of radial tire manufacturing, in particular to an isolating membrane for tire production and a preparation method of the isolating membrane. The invention provides an isolating membrane for tire production. The isolating membrane sequentially comprises an outer layer membrane, a middle layer membrane and an inner layer membrane from top to bottom, the thickness ratio of the outer layer film to the middle layer film to the inner layer film is (1-2): (8-10): (1-2); the outer-layer film and the inner-layer film are prepared from the following raw materials: metallocene polyethylene, high-density polyethylene, color master batch and liquid silane; the middle layer film is prepared from the following raw materials: a return material and a defoaming agent; according to the scheme, the metallocene polyethylene, the high-density polyethylene, the color master batch and the liquid silane are adopted to prepare the outer layer film and the inner layer ...
