Problems solved by technology

Among them, the one-component plastic paint has a low solid content and a solvent release of 70%, which is convenient for construction, but the paint film is not ideal in alcohol and chemical resistance; PU paint has a high solid content, and the solvent release is generally 50-40 %, at the same time, alcohol resistance and chemical resistance are good, but the fullness and leveling of the paint film are poor, which still cannot meet the industry requirements, especially the PU paint has a long drying time and contains a large amount of organic solvents, which has low efficiency and releases a large amount of Organic solvents pollute the environment; oil-based UV paint has all the advantages of PU paint, and at the same time the paint film is as bright as a mirror, but the traditional oil-based UV paint has poor adhesion on solid wood, hardwood, pumped wood and other substrates, so oily PU must be used Paint transition to increase adhesion, whil

Abstract

The invention discloses aqueous UV paint and a preparation method thereof. The aqueous UV paint comprises: by weight, 8 to 15% of aqueous aliphatic polyurethane Neorad R444, 40 to 55% of aqueous aliphatic polyurethane Neorad R447, 10 to 20% of an aqueous acrylic acid prepolymer Neorad R448, 2 to 6% of at least one initiator, 0.5 to 1.5% of at least one aqueous UV flatting agent, and 0.5 to 1.0% of at least one aqueous UV defoamer. The aqueous UV paint is prepared from the components having appropriate content. The aqueous UV paint has good leveling properties, good chemical resistance, good wear resistance, strong adhesion, good paint film flexibility and a very low solvent discharge capacity. The preparation method of the aqueous UV paint has simple processes, can be controlled easily, has high production efficiency, and is suitable for industrial production. An aqueous UV paint system prepared from the aqueous UV paint is stable.

Description

technical field [0001] The invention belongs to the technical field of paints, in particular to a water-based UV paint and a preparation method thereof. Background technique [0002] The development of coatings in the fields of black home appliances, white home appliances and 3C has developed rapidly in just 20-30 years. The coatings in this field are constantly changing and changing with one-component plastic paint, PU paint, oil-based UV paint, and water-based UV paint. Among them, the one-component plastic paint has a low solid content and a solvent release of 70%, which is convenient for construction, but the paint film is not ideal in alcohol and chemical resistance; PU paint has a high solid content, and the solvent release is generally 50-40 %, at the same time, alcohol resistance and chemical resistance are good, but the fullness and leveling of the paint film are poor, which still cannot meet the industry requirements, especially the PU paint has a long drying time ...
