A kind of inorganic water-based metallic paint and preparation method thereof

Abstract

The invention discloses inorganic water-based metallic paint and a preparation method thereof. The paint is prepared from raw materials in percentage by weight as follows: deionized water, an anti-freezing agent (ethylene glycol), a film-forming aid (dodecanol carbonate), a bactericide (Rohm and Haas LXE), an organic silicon defoaming agent (Rohm and Haas 505), a leveling agent (Rohm and Haas RM2020), nano titanium dioxide or nano zinc dioxide, sericite powder, nano calcium carbonate powder, potassium trimethylsilanolate, silica sol NM-1020, fumed silica, pearl powder, an emulsion and an associative alkali swelling thickener. The inorganic water-based metallic paint is uniform to spray during construction, the pearl powder is arranged orderly, the color is uniform, the luster of the pearl powder is completely restored, the surface is fine and smooth, and the hand feeling is fine and smooth.

Description

technical field [0001] The invention relates to a metal paint, in particular to an inorganic water-based metal paint and a preparation method thereof. Background technique [0002] Since the appearance of water-based organic metal paint, it has been welcomed and praised by people from all walks of life in construction, home furnishing, and accessories. The reason is that it is easy to construct. Any object or the interior and exterior walls of a building can be painted with simple tools. Painted by spraying, it is easier to achieve the effect of "golden" by pointing things. [0003] However, the water-based metallic paints currently on the market all belong to organic water-based metallic paints, which have the following defects: [0004] 1. Ordinary water-based metallic paint is mainly based on pearlescent powder as a filler, and a large amount of emulsion is used as a binder. Since the pearlescent powder is in the form of flakes, the specific gravity is about 0.9mg / kl, an...

AI Technical Summary

Problems solved by technology

[0004] 1. Ordinary water-based metallic paint is mainly based on pearlescent powder as a filler, and a large amount of emulsion is used as a binder. Since the pearlescent powder is in the form of flakes, the specific gravity is about 0.9mg / kl, and the surface tension is relatively large. The pearlescent powder is often suspended on the surface of the emulsion , cause local accumulation, serious color difference will appear after drying

[0005] 2. Pearlescent powder belongs to flake structure. Electrostatic coloring treatment will generate electrostatic interaction between flakes, which will be transmitted through water and emulsion carrier, and the gold flakes on the surface of the emulsion before spraying on the wall are often arranged on the surface. The problem of same-sex repulsion occurs, some of the pearlescent sheets are tilted at one end, cannot be arranged neatly, there is a difference in color between yin and yang, the surface is rough, and there is a thorny feeling

[0007] 4. After the emulsion is in contact with the pearl powder, the emulsion will turn black, which will cause black shadows on the surface of the metal paint; different black halos will be produced when viewed from different angles

[0008] In summary, ordinary water-based metallic paints cannot achieve spray uniformity during the construction process, and there are problems such as easy blooming on the surface, uneven gloss, yin and yang colors, dark shadows, rough surfaces, and thorny hands.
