Further, the bentonite is 1250 meshes.
Further, the paraffin-based oil is available under the trademark PM-300.
A use method of the environment-friendly release agent for the rubber film comprises the following steps:
s1, preparing a separant solution by mixing the separant containing the components and water in a ratio of 1:20-1:26 in parts by weight;
s2, fully stirring the separant solution obtained after the step S1 until suspended foam is formed on the water surface;
s3, the rubber film penetrates through the release agent solution, a layer of release agent solution film is coated on the surface of the rubber film, the moisture is fully dried through a drying device, and a layer of uniform release film is left on the surface of the rubber film, so that the film isolation is realized.
