Abstract

The invention relates to the technical field of coatings, and provides a real stone paint primer emulsion with good tear resistance and alkali resistance, the raw materials comprise a core layer raw material, a shell layer raw material and a priming raw material, the core layer raw material comprises the following components by weight: 20-40 parts of water for a core layer monomer emulsion, 0.5-4 parts of a core emulsifier, 0.5-3 parts of a core initiator, and 5-6 parts of water for the core initiator; the component A comprises, by weight, 20-50 parts of styrene, 15-35 parts of butyl acrylate, 0.5-3 parts of acrylic acid, 0-0.5 part of acrylamide and 0.5-2 parts of a chain transfer agent; the shell layer raw material is prepared from the following components in parts by weight: 25 to 35 parts of water for a shell layer monomer emulsion, 1 to 3 parts of a shell emulsifier, 0.7 to 4 parts of an oxidant, 4 to 5 parts of water for the oxidant, 1 to 3 parts of a reducing agent, 15 to 20 parts of water for the reducing agent, 10 to 40 parts of styrene, 5 to 10 parts of methyl methacrylate, 25 to 45 parts of butyl acrylate, 1 to 4 parts of methacrylic acid, 0 to 0.5 part of acrylamide and 0.5 to 3 parts of a polyfunctional group cross-linking agent. According to the technical scheme, the problems of poor tear resistance and alkali resistance of the primer emulsion for the real stone paint coating in the prior art are solved.

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...
