Technical Field
The invention relates to the technical field of coatings, in particular to an organic coating with a stealth effect.
Background
At present, the mainstream 'invisible Ink' in the market is colorless and transparent ultraviolet fluorescent Ink (UltravioletFluorescent Ink). The ultraviolet fluorescent ink is widely applied to base materials with permeability and low glossiness and has a good hiding effect under visible light, such as paper, packing materials, ceramics and other base materials. However, when the substrate material has no high permeability and a certain glossiness, such as resin coating, oil-based paint coating and metal, the hiding effect of the ultraviolet fluorescent ink under visible light is not good. In addition, the ultraviolet fluorescent ink has no alkali resistance, detergent resistance and organic solvent resistance, and the conservation of the service life of the ultraviolet fluorescent ink exposed in the air is estimated to be 2 years. Can not meet the requirements of performance and service life of some high-grade products.

Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The technical solutions of the present invention will be described clearly and completely with reference to the accompanying drawings and embodiments, and it is to be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The organic coating having the stealth effect according to the embodiment of the present invention is described below with reference to fig. 1 to 2 in combination with the embodiment.
The principle of the present technical solution firstly needs to discuss why the ultraviolet fluorescent ink can be observed by naked eyes in the visible light energy. Taking fig. 1 as an example, the coating layers are, from outside to inside: an ultraviolet fluorescent ink pattern 11; an acrylic resin coating layer 12; common oily color paint 13; black epoxy resin base powder 14; an aluminum substrate 15. The ultraviolet fluorescent ink pattern 11 is sprayed on the acrylic transparent resin coating 12 of the full-coating system by a dot matrix ink-jet printer, and the schematic diagram of poor invisible effect is shown.
The acrylic resin coating 12 is used as a base material to which the ultraviolet fluorescent ink pattern 11 is attached, and the drawn pattern is a dot-matrix sprayed QR two-dimensional Code (Quick Response Code). The acrylic resin coating 12 has high glossiness and is not easy to permeate, and the ultraviolet fluorescent ink 11 lattice can be attached to the substrate in a hill shape. The reason why the ultraviolet fluorescent ink two-dimensional code can be observed by naked eyes under visible light is well explained in the figure 1: high gloss surfaces can be specularly reflected. When ultraviolet fluorescent ink dot matrix hilly shape is attached to the surface of the ultraviolet fluorescent ink dot matrix, the angle of light reflected by the dot matrix is different from the angle of a mirror surface of a high-glossiness surface, so that the dot matrix part is slightly dim. Therefore, the content sprayed by the ultraviolet fluorescent ink can be observed under visible light. In addition, the transparency of the uv fluorescent ink is limited, and a pale white trace of the uv fluorescent ink can be observed on the material of the metal substrate.
When a new acrylic clear resin coating 20 is coated on the uv fluorescent ink pattern 11 coating after spraying the acrylic clear resin coating 20 on the uv fluorescent ink pattern 11 coating, a new specular reflection plane can be established. The condition that the drawn contents of the ultraviolet fluorescent ink pattern 11 are observed by naked eyes due to different light reflection angles is avoided. The active ingredient of the uv fluorescent ink pattern 11 is mainly transparent resin, which functions as a carrier of the fluorescent agent and enhances the ink adhesion. The active ingredients of the uv fluorescent ink pattern 11 have transparency similar to that of the acrylic transparent resin coating. The acrylic transparent resin 20 can well cover the pale trace generated by the uv fluorescent ink 11. The acrylic transparent resin coating 12 itself has good resistance to organic solvents, alkali and abrasion. The acrylic clear resin coating 20 covers the uv fluorescent ink coating to isolate it from external conditions and provide good protection for its physical and chemical properties. The acrylic resin itself is easily deteriorated by irradiation of ultraviolet rays. Therefore, an ultraviolet absorber is generally added to the acrylic solid powder coating. For example, 2- (2-2H-benzotriazole) -6- (1-methyl-1-phenyl) ethyl-4- (1, 1,3, 3-tetramethylbutyl) phenol. Therefore, the acrylic transparent resin coating layer 20 can absorb most of the ultraviolet rays of the sunlight under the daily conditions, thereby slowing down the photoaging rate of the ultraviolet fluorescent ink. The effective life of the fluorescent powder is prolonged, and the observation effect of the fluorescent powder under a 365nm ultraviolet light source can be ensured.
In some embodiments, an organic coating with a stealth effect includes a substrate having a pattern of ultraviolet fluorescent ink disposed thereon, the pattern being covered with a transparent solid powder coating. The substrate comprises a metal substrate or an acrylic resin coating, the pattern comprises a pattern made of ultraviolet fluorescent ink, the pattern comprises a QR two-dimensional code, and the QR two-dimensional code comprises a dot-matrix QR two-dimensional code. The solid powder coating comprises an acrylic resin solid powder coating. The ultraviolet fluorescent ink comprises a fluorescent agent and a transparent resin.
In some embodiments, in the first step, a full-coating template is taken, the coating system of which is the acrylic resin coating 12 in fig. 1; common oily color paint 13 and black epoxy resin base powder 14. And secondly, spraying various patterns such as two-dimensional codes, logos and the like on the surface of the sample plate by using an ultraviolet fluorescent ink 11 dot-matrix code spraying machine. And thirdly, placing the sprayed sample plate under electrostatic spraying equipment, and spraying acrylic transparent resin powder. And fourthly, feeding the sample plate into an oven to melt, level and solidify the acrylic resin. Resulting in the coating structure shown in fig. 2.
Compared with the prior art, the organic coating with the invisible effect has the following advantages:
(1) on the premise of ensuring that the drawn contents of the ultraviolet ink can be read normally under the irradiation of ultraviolet rays, the drawn contents are completely invisible under the sunlight.
(2) The coating system can isolate the drawn contents of the ultraviolet ink from the external conditions, avoid the exchange or reaction of the contents and external substances, and provide protection on physicochemical properties for the contents.
(3) The ultraviolet absorbent in the acrylic transparent resin powder can slow down the photoaging rate of ultraviolet rays in sunlight to the ultraviolet fluorescent ink, and provides protection on optical properties for the ultraviolet fluorescent ink.
(4) The acrylic transparent resin coating used by the coating system is a common outer coating in the automobile industry, has good impact resistance and abrasion resistance, and can meet the international requirement on the paint film performance of automobiles. The use of acrylic transparent resin as the cover layer for the uv fluorescent ink can introduce new appearance effects for the automotive market. Hidden anti-counterfeiting information can be attached to the visible area on the front surface of the automobile hub.
