Abstract

The invention relates to a water-soluble thermosetting acrylic resin and a preparation method thereof, belonging to the technical field of water-soluble thermosetting acrylic resin and a preparation method thereof. Including the following raw materials by weight: ethylene glycol monobutyl ether, isobutanol, isooctyl acrylate, n-butyl acrylate, hydroxypropyl acrylate, hydroxyethyl acrylate, styrene, methyl methacrylate, acrylic acid, propylene Acylmorpholine, 1,1-bis(tert-butylperoxy)cyclohexane, tert-butyl peroxybenzoate, isobutanol; additional charge 1: 1,1-bis(tert-butylperoxy)cyclohexane Alkane, butyl acetate; additional feed 2: 1,1‑bis(tert-butylperoxy)cyclohexane, butyl acetate; diluent: isobutanol. The resin of the present invention can easily solve the problems of water-based, firm adhesion, weather resistance and medium resistance of special acrylic baking coatings coated on special metal substrates (such as galvanized sheets, stainless steel, etc.).

Description

technical field [0001] The invention relates to a water-soluble thermosetting acrylic resin and a preparation method thereof, belonging to the technical field of water-soluble thermosetting acrylic resin and a preparation method thereof. Background technique [0002] As we all know, in people's life and production, metal parts are usually painted with paint, otherwise they will be rusted and unsightly. From the perspective of color, there are red, yellow, blue, white, black and other colors, which are the pigments in the paint. Yes, the coating can form a film and has good film-forming properties, which is mainly determined by the resin contained in the coating, that is, the film-forming substance. Coating experts all know that different substrates require different coatings, especially the film-forming substances in the coatings; the different coating methods also determine the different types of coatings selected. There are 18 categories of coating resins in the tradition...
