Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a genuine stone paint primer emulsion with good tear resistance and alkali resistance and a preparation method thereof. Background technique [0002] A primer is a paint that is applied directly to the surface of an object as a solid base for the topcoat. As an emulsion for primer coatings, it must have excellent water permeability and adhesion properties. One of the special primer emulsions is the primer emulsion used in real stone paint. Because in the actual construction process of real stone paint, it is necessary to apply the primer first, then paste the masking paper at a certain distance, then spray the real stone paint, and then tear off the masking paper, so the primer paint is very important for the real stone paint. The tear resistance of the textured paper is particularly important, and the primer coating on the textured paper will be exposed outdoors. Based on the...
