Waterproof metal paint for shell of filter and preparation method of waterproof metal paint

Abstract

The invention relates to waterproof metal paint for a shell of a filter and a preparation method of the waterproof metal paint. The waterproof metal paint is prepared from the following components in parts by weight: 31-36 parts of deionized water, 3-5 parts of talcum powder, 1-3 parts of titanite white powder, 1-3 parts of barium sulfate, 1-3 parts of an organic silicon defoamer, 1-3 parts of a flatting agent, 1-3 parts of nano-titanium dioxide, 16-21 parts of sericite powder, 5-8 parts of nano-calcium carbonate powder, 5-8 parts of potassium methyl silicate, 1-3 parts of fumed silica, 5-10 parts of pearl powder, 13-16 parts of an emulsion, 3-5 parts of an associated alkali swelling thickening agent, 6-10 parts of organic amine salt dispersing agent, 16-18 parts of a polyether polyol wetting agent, 9-13 parts of silicon carbide, 12-15 parts of aluminum oxide, 10-15 parts of graphite, 8-10 parts of tungsten carbide and 3-5 parts of boron nitride. The waterproof metal paint is a brand-new inorganic water-based paint, a sticking substance is silicate; the waterproof metal paint forms a film in a non-surface manner and can be fused together with a wall body to generate silicification reaction, when the metal paint is sprayed to a wall surface, silicate can directly permeate into the wall body, and the pearl powder can be directly attached to the wall surface, so that the chromatic aberration caused due to a stacking phenomenon is avoided.

Description

Technical field: [0001] The invention relates to a spray paint, in particular to a water-resistant metallic paint for a filter shell 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 a...

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 0.9m parts / kl, and the surface tension is relatively large. The pearlescent powder is often suspended in the emulsion Surface, causing 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.
