Abstract

The invention provides a water-based porcelain film coating. The formula of the water-based porcelain film coating comprises the following components in parts by weight: 45% to 55% of colloidal silica dispersion liquid, 30% to 45% of a silane coupling agent, 5% to 15% of an inorganic pigment, 2% to 5% of alumina packing, 0.5% to 1% of a flatting agent, 1% to 2% of hydroxy silicone oil with low molecular weight and 1% to 1.5% of an organic acid catalyst, wherein the colloidal silica dispersion liquid is prepared by mixing colloidal silica with big and small particle diameters according to the mass ratio of (1-3):1, wherein the particle diameters of the colloidal silica with the small particle diameters are distributed within 10nm to 15nm while the particle diameters of the colloidal silica with the big particle diameters are distributed within 40nm to 50nm; the silane coupling agent is prepared by mixing methyl trimethoxysilane and methyl triethoxysilane according to the mass ratio of (1-2):1; the organic acid catalyst can be a formic acid or an acetic acid or can be a mixture of the formic acid and the acetic acid. The water-based porcelain film coating has the good adhesive force and the good waterproof and cohesive-proof on an aluminum alloy substrate.

Description

Technical field [0001] The invention relates to the technical field of water-based inorganic coatings. Background technique [0002] At present, most of the coatings used in the coating industry are organic coatings, and water-based inorganic coatings are limited to inorganic zinc-rich or inorganic phosphate coatings. This type of coating only has protective properties for the bottom layer and does not have decorative functions. . [0003] The current inorganic coatings currently have two main drawbacks: first, the current inorganic coatings are generally matt and semi-matt, and generally lack decoration; second, the current inorganic coatings lack similar water resistance and long-lasting anti-sticking properties. [0004] Therefore, it is necessary to develop a water-based inorganic coating with better brightness and better water resistance. Summary of the invention [0005] In order to make up for the shortcomings of the prior art, the present invention provides a water-based cer...
