Problems solved by technology

This silver mirror plating using an ammoniacal silver nitrate solution has the following conditions: chalking (also called whitening or powdering) peculiar to plating occurs; or cracks are generated; or the film thickness becomes uneven; or due to the formation of silver mirror The color development (metallic luster) of the silver mirror plating surface is uneven due to uneven aggregation of plated silver nanoparticles
And then, this silver mirror coating also has the following problems: the part that does not need to implement the silver mirror coating is also sometimes coated with the silver mirror at first, and the problem that the defective rate is higher; Surface peeling problem

experiment example 1

[0115] (primer coating film)

[0116] The silicon oligomer containing alkoxy group (GLANZCOAT Type RT BlackPrimer G, FECT (stock)) as the main ingredient of the primer paint is 6 parts by mass, ethanol as a solvent is 7 parts by mass, and the hardener (GLANZCOAT typeRT Primer G Hardener U, FECT (stock)) was uniformly stirred and mixed at a ratio of 1 part by mass to prepare a primer paint. The primer coating was spray-coated on the surface of a standard test piece as a base material, and then forced-dried at 100° C. for 30 minutes to obtain a standard test piece sample with a primer coating film formed thereon.

[0117] (silver mirror coating)

[0118]As the composition liquid for forming the silver mirror film layer, use the commercially available combination liquid (GLANTZCOAT TypeRT Silver) prepared based on the patent document 3, and utilize the thinner (GLANTZCOAT TypeRT Silver thinner T2) to form the silver mirror film layer. It was diluted to 2 times and sprayed, and ...

experiment example 2

[0122] As the solvent of the primer paint and the top paint paint, use isopropanol instead of ethanol, in addition, in the same manner as in the case of Experimental Example 1, a primer paint film and a silver mirror film layer were formed on the surface of the standard test piece. And the silver mirror film layer of the experimental example 2 of topcoat film forms the sample.

experiment example 3

[0124] As the solvent of primer paint and topcoat paint, butanol is used instead of ethanol, except that, in the same manner as the situation of Experimental Example 1, a primer paint film, a silver mirror film layer, and a primer film are formed on the surface of the standard test piece. The silver mirror film layer formation sample of Experimental Example 3 of the topcoat film.

Abstract

A surface decoration structure 10 according to one embodiment of the present invention is obtained by forming a primer coating film 12, a silver mirror film layer 13 and a top coating film 14 on the surface of a substrate. The silver mirror film layer 13 is formed by laminating nanometer-sized silver particles, the surfaces of which are covered with a polymer dispersant; the top coating film 14 isformed using a coating material that contains, as a solvent, at least one substance selected from among aliphatic hydrocarbon compounds, aliphatic hydrocarbon compound solutions containing 10% by mass or less of an aromatic compound, and diisobutyl ketone. At least one of the primer coating film 12 and the top coating film 14 may contain a rust inhibitor; and the silver mirror film layer 13 may also contain a rust inhibitor. According to this embodiment, a surface decoration structure which has good luster, while being provided with a silver mirror film layer having good corrosion resistanceis able to be achieved.

Description

technical field [0001] The invention relates to a surface decoration structure with a silver mirror film layer with good specular luster and a forming method thereof, in particular to a silver mirror film layer which is not easy to produce discoloration or peeling off by a coating method. The surface decoration structure of the mirror film layer and its forming method. Background technique [0002] Silver (Ag) has a high light reflectance in the visible region and has a beautiful metallic luster. If a silver mirror film is formed on a substrate such as resin or metal, it will show a beautiful metallic luster, so it is expected to apply silver to interior or exterior parts of automobiles, bicycles, fishing gear, mobile phones, notebook computers, cosmetic containers, etc. mirror layer. For example, in the case of automobiles, painting is carried out to protect the main material of the automobile (steel or plastic sheet in most cases) and to improve the appearance of the aut...
