Embodiment 7

[0064] Embodiment 7: a kind of long-acting self-cleaning water-based inorganic nano-ceramic coating, its preparation method is:

[0065] Step 1: Mix the silane in Example 1-6 with the organosilicon modifier and the hydroxy-functional organosilicon oligomer, and mix evenly until the organosilicon modifier and the hydroxy-functional organosilicon oligomer are completely Disperse evenly in the silane system to form a transparent silane mixed liquid; then add silica sol and water to the silane mixed liquid and stir for 20 minutes;

[0066] Step 2: Then raise the temperature slowly, keep the reaction temperature at 50 degrees, stir and react at constant temperature for 5 hours, then stop stirring, keep warm for 2 hours, then add measured water, cool down and cool down, and the appearance can be milky white translucent or opaque low viscosity Liquid aqueous self-cleaning inorganic nanoceramic emulsion.

[0067] The third step is to mix the water-based self-cleaning inorganic nano-c...

Abstract

The invention relates to a long-acting self-cleaned aqueous inorganic nano ceramic coating and a preparation method thereof. The ceramic coating consists of an aqueous self-cleaned inorganic nano ceramic emulsion, a pigment, a packing, a lubrication dispersant, a defoaming agent, a rheological agent, water and the like. The preparation method comprises the following steps: mixing one or multiple silanes with an organic silicon modifier and hydroxyl functional group organic silicon oligomer so as to obtain a transparent mixed silane liquid; putting silica sol and water into the transparent mixed silane liquid, and stirring, slowly heating, stirring at a constant temperature, leaving to stand, keeping the temperature, adding water, and cooling so as to obtain an aqueous self-cleaned inorganic nano ceramic emulsion; mixing the prepared aqueous self-cleaned inorganic nano ceramic emulsion with the pigment and the packing, and dispersing and grinding at a high speed; after grinding is completed, uniformly stirring with an aid and water, so as to obtain the long-acting self-cleaned aqueous inorganic nano ceramic coating. The coating product provided by the invention is a lyophobic anti-graffiti long-acting self-cleaned coating with excellent properties of high density, high hardness, good wearing resistance, super good weather resistance and integration from inside to outside.

Description

technical field [0001] The invention relates to the technical field of coatings, in particular to a water-based ceramic coating with self-cleaning function and a preparation method thereof. Background technique [0002] As environmental pollution continues to intensify, more and more serious smog, oily smog, and exhaust gas have brought serious erosion to high-rise buildings, curtain walls, and bridges, affecting their aesthetics, functionality, and durability. Poor stain resistance is a common shortcoming of traditional outdoor decorative protective coatings, which restricts its application to a certain extent. At the same time, cleaning the polluted building exterior walls not only requires high investment, but also the use of surfactants will cause serious pollution to the environment. Therefore, in view of the problem of insufficient stain resistance of the current outdoor coatings, functional coatings with self-cleaning effects have emerged as the times require. Self-...
