Abstract

The invention provides a hydrophilic intermediate paint, which is characterized by comprising the following components in parts by weight: 3-4 parts of acrylic resin; 2-3 parts of amino resin; 60-70 parts of pigment; 0.5-1.26 parts of auxiliary agent parts; solvent 27.3 to 33.6 parts. The present invention also provides a preparation method of the hydrophilic mid-coat paint. The hydrophilic mid-coat paint preparation method and the mid-coat paint product of the present invention use acrylic resin and amino resin as reaction main bodies, and are equipped with pigments and fillers. The hydrophilic auxiliary agent can effectively solve the sag phenomenon caused by the incompatibility of water and oil, thereby solving the defects that occur when the oily mid-paint is matched with the water-based topcoat; the preparation method of the invention has a simple process and is suitable for industrial production.

Description

technical field

[0001] The invention belongs to the technical field of paint preparation, and in particular relates to a hydrophilic intermediate paint applicable to automobile topcoats and a preparation method thereof. Background technique

[0002] At present, automobile topcoats are usually composed of composite coatings. The spraying techniques and coatings commonly used by automobile manufacturers in spraying car paints on the body mainly include the following types: one is water-based intermediate paint supporting water-based topcoat, and the other is water-based intermediate paint. Water-based topcoat (3C1B) without preheating, and water-based topcoat for oil-based intermediate paint. Generally, when water-based intermediate paint is matched with water-based topcoat and oil-based intermediate paint is matched with oil-based topcoat for spraying, its compatibility is better; however, when oil-based intermediate paint is matched with water-based topcoat, its compatibilit...
