Abstract

The invention relates to the technical field of new material processing, and discloses a preparation method of a scrub-resistant water-based aluminum paste paint film. The preparation method comprisesthe following steps: researching the properties of an aluminum paste material, adding a prepared aluminum paste dispersion by using an acrylic epoxy polyester resin emulsion as a matrix to obtain a water-based paint containing aluminum paste, and carrying out film coating. A prepared rare earth stabilizer can be adsorbed and combined with aluminum in the aluminum paste to prevent the aluminum paste from being oxidized, the glossiness of aluminum can be enhanced, the rare earth stabilizer stably exists as a pigment of water-based paint, and the problems that an existing aluminum paste modification method is poor in washing resistance and the glossiness is affected are solved. According to the invention, the scrub resistance of the aluminum paste as a pigment in a paint film can be remarkably improved, the aluminum paste is stable to use under the conditions of acid, alkali, high temperature and the like, the prepared paint film has excellent adhesive force and high hardness and is noteasy to fall off and lose color, and various problems of the existing solvent type aluminum paste paint film are solved.

Description

technical field [0001] The invention belongs to the technical field of new material processing, and in particular relates to a preparation method of a scrub-resistant water-based aluminum-silver paste paint film. Background technique [0002] Aluminum silver paste, also known as aluminum powder paste, flash paste, silver paste. Its main components are flake-like aluminum particles and petroleum solvent, and it is in the form of a paste. It is characterized by smooth and flat surface of aluminum flakes, concentrated particle size distribution, regular shape, excellent light reflection ability and metallic luster, mixed with transparent color pigments, the paint film has obvious "angle-dependent color effect", and the decorative effect is very gorgeous beautiful. Aluminum silver paste is widely used in many fields such as automobile paint, motorcycle paint, bicycle paint, plastic paint, architectural paint, ink, mobile phone casing and buttons, electromechanical casing, elec...
