Problems solved by technology

[0002] At present, the ceramic coatings on the market are basically preheated ceramic coatings, that is, ceramic coatings for preheating construction. The substrate needs to be preheated to a certain temperature before construction can be carried out. Otherwise, sagging and low gloss will occur. , poor surface effect, particles, insufficient film thickness and other disadvantages, especially in the construction of large-scale building curtain walls, problems are

Abstract

The invention belongs to the field of coatings, the invention discloses a ceramic coating, which comprises a primer and a finishing paint. The primer is prepared from the following components in partsby weight: 30 to 60 parts of waterborne nano silica sol resin, 30 to 50 parts of water, 3 to 25 parts of a filler, 3 to 20 parts of pigment, 0.1 to 3 parts of a thickener, 30 to 60 parts of a silanecoupling agent, 0.1 to 3 parts of a leveling agent, 0.1 to 3 parts of non-stick additive and a pH regulator; and the finish paint comprises the following components in parts by weight: 30-60 parts ofwater-based nano silica sol resin, 30-50 parts of the water, 0.1-3 parts of the thickener, 30-60 parts of the silane coupling agent, 0.1-3 parts of the leveling agent, 0.1-3 parts of the non-stick additive, 0.1-3 parts of the pigment and the pH regulator. The ceramic coating provided by the invention overcomes the problems of unsatisfactory temperature resistance, flame resistance and hardness oftraditional organic coatings, can resist a high temperature of 450 DEG C or above for a long time, can resist a high temperature of 600 DEG C or above for a short time, and has excellent thermal stability, wear resistance, scratch resistance and incombustibility.

Description

technical field [0001] The invention belongs to the field of coatings, and in particular relates to a ceramic coating and a preparation method thereof. Background technique [0002] At present, the ceramic coatings on the market are basically preheated ceramic coatings, that is, ceramic coatings for preheating construction. The substrate needs to be preheated to a certain temperature before construction can be carried out. Otherwise, sagging and low gloss will occur. , poor surface effect, particles, insufficient film thickness and other disadvantages, especially in the construction of large-scale building curtain walls, problems are more likely to occur. However, this kind of construction requirements cannot be well met by many spray coating manufacturers, and it is easy to cause construction problems and various coating film defects. Also, the construction of this kind of preheating ceramic coating will change with the change of the weather. It is relatively easy to const...
