the finishing paint comprises the following raw materials in parts by weight: 100-200 parts of alkaline silica sol, 70-120 parts of siloxane, 1-2 parts of accelerator, 31-75 parts of antibacterial agent, 5-35 parts of hollow glass beads and 8-25 parts of filler.
The primer is an organic silicon primer which has high adhesive force and impact resistance, the substrate and the finish are connected through the organic silicon primer, so that the finish can be better attached to the substrate, the toughness of the finish is improved, the defect that the finish is high in brittleness and easy to crack after film forming due to the fact that the finish is used alone can be avoided, if only the finish is used, the adhesive force of the finish on the substrate is grade 1, and the adhesive force can reach grade 0 through the matched and combined use of the primer and the finish.
The film forming principle of the primer and the finish paint is that siloxane is heated to carry out self-polymerization crosslinking to form a film, and the siloxane is promoted to carry out self-polymerization crosslinking in the presence of alcohol or water in a heating mode.
Specifically, the reason why the adhesion force of the finish paint used alone is low is that alcohol or aqueous solution of siloxane in the finish paint contains silanol groups, and a large amount of silanol groups are subjected to self-polymerization crosslinking during heating and curing, so that bonding groups between the finish paint and the surface of the metal substrate are reduced, and the adhesion force is low. The primer is sprayed first and the finishing paint is sprayed second, and the epoxy resin in the primer has great amount of strong polar groups in its molecular chain to form strong adhesive force between the primer and the surface of the metal base material. Meanwhile, trimethoxy silane in the primer and siloxane in the finish paint can promote self-polymerization crosslinking reaction in the presence of alcohol or water in a heating mode, and the primer and the finish paint can be perfectly combined with each other through the characteristics of siloxane resin, so that the primer plays a role in starting up, the base material and the finish paint can be better bonded together, the adhesive force and the impact resistance of the ceramic coating are improved, the adhesive force is 0 grade, and when a 50 kilogram impact resistance test is carried out, the surface of the base material treated only by the finish paint is cracked.
Specifically, siloxane in the finish paint is stable to heat and chemical reagents, silica sol is nano-scale silica particles, and the siloxane and the silica sol are uniformly mixed under the action of an accelerator, so that the finish paint has the performances of temperature resistance and high strength; the hollow glass bead is a hollow spherical powder-shaped ultra-light inorganic non-metallic new material with excellent performance, and can improve the heat-insulating performance after coating forming; the antibacterial agent is added into the finish paint, so that bacteria bred on the surface of the coating can be effectively killed, and an antibacterial effect is achieved; the addition of fillers in the topcoat can further improve the properties of the coating.
Wherein, the accelerant in the finish paint can play a role in promoting the self-polymerization crosslinking of the siloxane resin, and the accelerant is one or more of citric acid, glacial acetic acid or oxalic acid.
Therefore, the ceramic coating disclosed by the invention is compounded and used by matching the primer and the finish, so that the adhesive force between the ceramic coating and the substrate can be greatly improved, the toughness of the ceramic coating is improved, the ceramic coating with more excellent performance and more comprehensive functions can be obtained, the requirements of users are met, and meanwhile, the ceramic coating disclosed by the invention is a water-based coating, and the national requirements on water-based coating, environmental protection and health are met.
Preferably, the antibacterial agent in the finish paint comprises 30-65 parts of nano titanium dioxide and 1-10 parts of water-soluble nano silver ion solution in parts by weight.
Specifically, the nano titanium dioxide can decompose bacteria under the photocatalysis effect to achieve the antibacterial and bactericidal effects, silver ions in the water-soluble nano silver ion solution pierce the cell surface and are combined with bacterial protein, so that cell DNA is damaged, the formation of protein is inhibited, cells cannot metabolize and propagate until the cells die, the antibacterial effect is achieved, and the nano titanium dioxide and the bacterial protein are used together to achieve the stronger antibacterial effect.
Preferably, in the finish paint, the filler comprises 5-10 parts of wear-resistant powder and 3-15 parts of whisker silicon by weight.
The addition of the crystal whisker silicon and the wear-resistant powder in the finish paint can improve the wear resistance and scratch resistance of the coating formation. Specifically, the whisker silicon has a unique fibrous body structure, the surface hardness reaches Mohs 7 grade, and the whisker silicon can be matched with wear-resistant powder to obviously improve the surface hardness of a coating and improve the scratch resistance and the scrubbing resistance.
Preferably, the finish paint also comprises 0-20 parts of aqueous solvent and 0.2-2 parts of surfactant according to parts by weight; the aqueous solvent is deionized water or distilled water. The surface active agent is added into the finish paint, so that the adhesive force and the surface condition of a coating film can be further improved, and the surface active agent in the finish paint is a polyether nonionic surface active agent.
Specifically, the alkaline silica sol in the finish paint component contains moisture, and if the moisture in the alkaline silica sol reaches the content required by siloxane self-polymerization crosslinking, no aqueous solvent or a small amount of aqueous solvent is required to be added; the addition amount of the water-based solvent exceeding 20 parts can cause excessive dilution on resin components and influence the performance of the finish paint after curing and film forming.
Preferably, the primer further comprises 0-20 parts of titanium dioxide, 0-30 parts of heavy calcium powder, 1-5 parts of BYK-3333 leveling agent and 2-5 parts of surfactant according to parts by weight.
The titanium dioxide and the coarse whiting powder in the primer mainly play a role in filling and covering the ground color of the base material, and the prepared primer is transparent varnish if the titanium dioxide and the coarse whiting powder are not added; the prepared primer is white paint, and the proper weight parts can be selected according to different base materials and the requirements of consumers.
Specifically, the surfactant in the primer is a polyether nonionic surfactant.

It is worth noting that the fineness of the wear-resistant powder is too coarse, which causes the surface of the ceramic coating to be rough and uneven after film formation, and the fineness of the wear-resistant powder is preferably less than 15 μm.
Preferably, the spraying thickness of the primer is 5-15 μm, and the spraying thickness of the finishing coat is 8-25 μm.
