Abstract

The invention discloses an acrylic resin emulsion for fingerprint-resistant paint and a preparation method thereof. The acrylic resin emulsion for fingerprint-resistant pain is polymerized from the following components in parts by weight:35-40 parts of methyl methacrylate, 5-10 parts of methyl acrylate, 30-35 parts of ethyl methacrylate, 10-15 parts of acrylic acid, 0.1-0.2 part of initiator, 2-4parts of emulsifying agent, 8-12 parts of cosolvent and 150-200 parts of deionized water. The acrylic resin emulsion has the advantages of uniform system, uniform viscosity and favorable ionic stability, and can satisfy the requirement of quick curing without degrading the film-forming properties of the resin. When the fingerprint-resistant paint prepared from the acrylic resin emulsion is coatedon the surface of a galvanized steel sheet, fingerprints can not be attached to the surface, and the paint is environment-friendly.

Description

Technical field [0001] The invention relates to an acrylic resin emulsion and a preparation method thereof, in particular to an acrylic resin emulsion for fingerprint resistant coatings and a preparation method thereof. Background technique [0002] As an environmentally friendly coating, water-based resin is one of the current hot spots in the research and development of coatings. There are three ways to make the resin water-based: (1) make the resin salt and dissolve in water (2) use the -OH or ether bond in the resin skeleton Hydrophilic genes make the resin soluble in water (3) rely on surfactants to solubilize and dissolve in water. The first two methods are mainly used to manufacture water-based coatings, and the latter method is mainly used to make emulsions. Therefore, the first two methods are generally two-component water-based resins, which require a certain amount of curing agent and catalyst to be added to the coating to accelerate The coating film is dried, and the...
