Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings.
Referring to fig. 1, in the specific implementation of the present invention, a surface structure of a high performance coating with an electroplated mirror effect is characterized by a high performance mirror surface structure based on indium metal particles, which is characterized in that: the surface structure is composed of the following three layers from bottom to top respectively:
a. coating a primer;
b. a coating of indium metal particles;
c. and (4) varnish coating.
Wherein, the indium metal particle coating b needs to satisfy the following characteristics:
(1) The indium metal particle coating for forming the indium metal particle coating is formed by only mixing indium metal particles and an organic solvent or water;
(2) The film thickness of the indium metal particle coating is less than 1 micron;
(3) The indium metal particles composing the indium metal particle coating are spherical or flaky;
(4) The average size of the indium metal particles constituting the indium metal particle coating layer is 60 nm or less.
In addition to water electroplating and vacuum plating, aluminum metal or silver metal is used as a mirror coating material for presenting metal color tone in the market at present, and the solution is the main electroplating mirror surface solution in the market. Wherein, the water electroplating can generate a large amount of heavy metal wastewater, the vacuum plating has larger size limitation and insufficient performance, so the mirror coating can solve the problem that the water electroplating and the vacuum plating are difficult to solve due to better constructability, flexibility and environmental protection.
Most of mirror coatings on the market use aluminum metal or silver metal as metal particles presenting metal tones, both the aluminum metal and the silver metal belong to metal elements with active chemical properties, even if the coatings are protected by anti-UV finishing paint or other high-performance finishing paint, the metal still easily reacts with light and water in the air, the coatings gradually turn black and lose luster along with the passage of time, and the change is particularly rapid in severe environment. Therefore, indium metal, which is chemically inactive, has good light stability and moisture resistance, and indium metal particles used as a coating material for forming a metallic luster film layer can solve the problems of light resistance and moisture resistance that cannot be solved by aluminum metal or silver metal.
The indium metal particle paint constituting the indium metal particle coating layer is formed by mixing only indium metal particles and an organic solvent or water, because the indium metal particles form a highly reflective metal film, which needs to satisfy the following two conditions: 1. the metal particles are stacked compactly; 2. the metal particles are uniformly distributed. In the case where the metal particles are formed by mixing only an organic solvent or water and do not contain a resin or other filler, the metal film layer formed by high-temperature volatilization or evaporation of the solvent or water does not contain other filler, and in such a case, the metal particles are mutually bonded by van der waals force to form a uniform and dense film layer, and thus the surface roughness is reduced and a highly reflective visual effect is achieved.
The film thickness of the indium metal particle coating layer is 1 μm or less because the organic solvent or water is not sufficiently volatilized during the application of the coating material containing the indium metal particles. If the thickness of the indium metal particle coating is too thick, the indium metal particles on the surface layer are separated from the diluting medium to be densely formed into a film in the drying process of the coating, and the inner layer coating still contains the non-volatile or evaporated organic solvent or water which tries to burst the dense metal film on the surface layer to destroy the dense arrangement of the metal particles on the surface layer, so that the coating is in diffuse reflection and loses luster.
The indium metal particles constituting the indium metal particle coating layer are spherical or flaky in shape because the spherical or flaky shape is an ideal particle shape in which the indium metal particles are densely formed by van der waals bonding, wherein during the film formation process of the spherical metal particles, the metal particles tend to distribute and densely stack toward a portion where the film thickness of the metal surface is low, thereby forming a dense metal thin film having a uniform film thickness, and the metal thin film has a shape as shown in fig. 2; during the film forming process, the dense stacking of the flaky metal particles reduces the surface roughness, so that a dense metal thin film with uniform film thickness is formed, and the morphology of the metal thin film is shown in fig. 3.
The average size of the indium metal particles constituting the indium metal particle coating layer is 60 nm or less because higher metal particles will result in higher roughness, reducing glossiness.
Preferably, the primer coating of the surface structure a is formed by selecting any one of the following five types: (1) A two-component resin coating formed by the reaction of isocyanate and hydroxyl; (2) A two-component resin coating formed by reacting an amino group-containing resin and an epoxy group-containing silicon compound; (3) A two-component or three-component resin coating in which the reaction of the above (1) and the reaction of the above (2) occur simultaneously; (4) epoxy resin paint; (5) A resin coating is formed by reacting isoflavones and hydroxyl groups.
This is because the diluting agent in the indium metal particle coating reacts with the unreacted resin (isocyanate or epoxy group-containing silicon compound) of the primer coating film, and the adhesion between the primer coating film and the indium metal film increases.
Preferably, the varnish coating of the surface structure c is formed by selecting any one of the following five types: (1) A two-component resin coating formed by the reaction of isocyanate and hydroxyl; (2) A two-component resin coating formed by reacting an amino group-containing resin and an epoxy group-containing silicon compound; (3) A two-component or three-component resin coating in which the reaction of the above (1) and the reaction of the above (2) occur simultaneously; (4) epoxy resin paint; (5) A resin coating is formed by reacting isoflavones and hydroxyl groups.
This is because the diluting agent remaining in the indium metal particle coating material reacts with the resin (isocyanate or epoxy group-containing silicon compound) in the clear coat film, and the adhesion between the primer coating film and the indium metal film increases.
Preferably, the indium metal particle coating constituting the indium metal particle coating of the surface structure b has a solid content of more than 1% and less than 10%.
The effect of this is that, as described above, the indium metal particle coating material is composed only of indium metal particles and an organic solvent or water, and therefore the content of indium metal particles contained in the indium metal particle coating material is the solid content thereof. If the solid content is too low, the indium metal particles are difficult to arrange densely, so that the coating film is discontinuous; if the solid content is too high, the indium metal particles are stacked too thick, resulting in the above-described phenomena of tarnishing, diffuse reflection, and the like.
Preferably, the surface roughness Ra of the indium metal particle coating of the surface structure b is less than 30 nm.
The effect is that the indium metal particle coating can generate mirror surface effect similar to the traditional water electroplating under the condition that the surface roughness Ra is less than 30 nanometers.
Preferably, the indium metal particle coating layer of the surface structure b has a 60 degree incident angle glossiness of 300Gu or more.
The effect is that the indium metal particle coating can generate mirror surface effect similar to the traditional water electroplating when the glossiness is more than 300Gu at the incidence angle of 60 degrees.
Preferably, the uv absorber is contained in the clear coat layer of said surface structure c in a percentage by volume not lower than 2.7%.
The ultraviolet-resistant coating has the effects of further increasing the ultraviolet resistance of the whole coating system and enhancing the weather resistance and durability of the coating system in severe environments such as automobiles, motorcycles, outdoor exhibition and the like.
