Abstract

The invention discloses a water-soluble amino acrylate resin coating and a preparation method thereof. Butanol, styrene, titanium dioxide, benzoyl peroxide, ethylene glycol monobutyl ether, epichlorohydrin, methyl etherified Melamine, modified bentonite, methacrylic acid, calcium carbonate, drier, chlorinated paraffin, ethyl acrylate and plasticizer, butanol is added to the reaction kettle with agitator, thermometer and reflux condenser to heat up, and Mix methacrylic acid, styrene, ethyl acrylate and benzoyl peroxide evenly, then slowly drop them into the reactor, add ethylene glycol monobutyl ether and methyl etherified melamine, react at constant temperature, add titanium dioxide and epichlorohydrin After cooling, add the remaining raw materials and grind to get the product; product viscosity 2.5~3.5Pa·s, adhesion 1~2 grade; surface dry time 20~30min, hard dry 50~60min; coating film soaked in saturated calcium hydroxide for 15 ?25d without blistering, wrinkled skin; soaked in water for 30-40d without falling off, blistering, can be widely produced and continue to replace existing materials.

Description

technical field [0001] The invention relates to a coating, in particular to a water-soluble aminoacrylate resin coating and a preparation method thereof, belonging to the technical field of water-soluble coatings. Background technique [0002] Paint (paint), what we usually call paint is just one of them. Refers to a type of liquid or solid material that can form a thin film coated on the surface of an object under certain conditions for protection, decoration or other special functions (insulation, rust prevention, mildew resistance, heat resistance, etc.). Because most of the early paints used vegetable oil as the main raw material, they are also called paints. The synthetic resin has replaced the vegetable oil, so it is called paint. Coatings are not liquid, and powder coatings are a large category of coatings. Coatings are usually based on resin or oil, with or without pigments, fillers, viscous liquids prepared with organic solvents or water, and new varieties of coa...
