Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a housing according to an embodiment of the present disclosure. The embodiment of the application provides a casing 10, including outer texture layer 121, body 110, interior texture layer 122, optics rete 130, first end ink layer 141, one side that body 110 was located to outer texture layer 121, one side that body 110 deviates from outer texture layer 121 is located to interior texture layer 122, one side that interior texture layer 122 deviates from body 110 is located to optics rete 130, one side that interior texture layer 122 deviates from body 110 is located to first end ink layer 141, one side that optics rete 130 deviates from interior texture layer 122 is located to first end ink layer 141, contain radium carving powder in the first end ink layer 141.
Laser engraving is a marking method in which a workpiece is locally irradiated with a high-energy-density laser beam to cause a physical or chemical change in the irradiated portion, thereby leaving a permanent mark. When the housing 10 of the embodiment of the present application is used for laser engraving, a laser beam may pass through the outer texture layer 121, the body 110, the inner texture layer 122, and the optical film layer 130 to reach the first bottom-covering ink layer 141, and laser energy may cause a physical change and/or a chemical reaction in the first bottom-covering ink layer 141 to further change color, thereby forming a mark on the housing 10.
Illustratively, when the chemical composition in the first under ink layer 141 includes a simple substance of carbon, the energy of the laser beam may oxidize the simple substance of carbon into a gas (e.g., carbon monoxide, carbon dioxide, etc.), and the gas is present in the form of white bubbles in the first under ink layer 141, thereby forming a white mark.
Laser engraving powder, namely laser additives, laser powder, laser marking additives, laser master batches, laser marking materials and the like can absorb laser energy, so that laser beams are converted into heat energy, the engraved materials are heated, carbonized, vaporized, evaporated and the like, and the definition of marks formed by laser engraving can be improved.
As shown in fig. 1, it can be seen that a side surface of the outer texture layer 121 away from the body 110 has a plurality of pointed protrusion structures, and the pointed protrusion structures are used to reflect light on the pointed protrusion structures to generate an astigmatism effect, so that the housing 10 has a visual effect of multiple flashing lights, that is, the housing 10 in the embodiment of the present application is also a flash sand outer texture housing, but the pointed protrusion structures on the surface of the outer texture layer 121 also make the surface of the outer texture layer 121 rough, and when a laser beam irradiates the outer texture layer 121, the rough surface of the outer texture layer 121 can reflect about 50% of the laser, so that the laser energy entering the first cover bottom ink layer 141 is only about 50%, and since the laser energy entering the first cover bottom ink layer 141 is relatively low, the engraved mark becomes unclear. Referring to fig. 2, fig. 2 is a schematic view illustrating an effect of a mark formed when a conventional flash sand outer texture shell is laser engraved. It can be seen that the mark carved on the shell 10 in fig. 2 is not clear, and it should be noted that no laser carving powder is added to the first bottom-covering ink layer 141 of the existing shell with the external texture of flash sand, and no other measures for improving the carving effect are taken.
Illustratively, the material of the outer texture layer 121 may be transparent paint, and the outer texture layer 121 serves as an outermost film layer of the casing 10, may play a role in protecting other structural layers inside the casing 10, and has properties of wear resistance, scratch resistance, and the like.
The shell 10 of this application embodiment is through adding radium carving powder at the bottom of first lid printing ink layer 141, because radium carving powder can absorb laser energy, converts the laser beam into heat energy, consequently can make and take place physical change and/or chemical reaction in the printing ink layer 141 at the bottom of the first lid, and then forms the higher mark of definition. Referring to fig. 3, fig. 3 is a schematic view illustrating an effect of a mark formed when a housing of the embodiment of the present application is laser engraved. It can be seen that the housing 10 of the embodiment of the present application forms a very clear mark after laser engraving.
For example, the label engraved on the housing 10 may be an International Mobile Equipment Identity (IMEI), which is commonly called a Mobile phone serial number and a Mobile phone "serial number", and is used for identifying Mobile communication Equipment, such as each independent Mobile phone, in a Mobile phone network, and is equivalent to an Identity card of the Mobile phone.
Illustratively, the laser etching powder may be mica powder. Of course, the laser engraving powder can also be other substances which can promote the absorption of laser energy and further enable the formed mark to be clearer in the laser engraving process.
The material of the first bottom-covering ink layer 141 may include ink and laser etching powder, where the mass ratio of the laser etching powder to the ink may be (0.5-1.5): (8.5-9.5), for example, 0.5. Illustratively, the mass ratio of the laser etching powder to the ink may be 1.
It will be appreciated that the first under-ink layer 141 primarily serves to define the color of the housing 10. Illustratively, the first under-cap ink layer 141 may employ black ink, such as CC11727 or CC 11729.
Referring to fig. 1, the casing 10 may further include a second cover bottom ink layer 142, a third cover bottom ink layer 143, a fourth cover bottom ink layer 144, and a fifth cover bottom ink layer 145, wherein the second cover bottom ink layer 142 is disposed on a side of the first cover bottom ink layer 141 departing from the optical film layer 130, the third cover bottom ink layer 143 is disposed on a side of the second cover bottom ink layer 142 departing from the first cover bottom ink layer 141, the fourth cover bottom ink layer 144 is disposed on a side of the third cover bottom ink layer 143 departing from the second cover bottom ink layer 142, and the fifth cover bottom ink layer 145 is disposed on a side of the fourth cover bottom ink layer 144 departing from the third cover bottom ink layer 143.
The second bottom ink layer 142, the third bottom ink layer 143, and the fourth bottom ink layer 144 may all be ink layers with flame retardant property, so as to improve the flame retardant property of the housing 10.
The second bottom-cover ink layer 142 and the third bottom-cover ink layer 143 may be black ink layers, i.e. the same color as the first bottom-cover ink layer 141. For example, the second cover base ink layer 142 and the third cover base ink layer 143 may both adopt black flame retardant ink CC98020. When second cover base ink layer 142 uses black flame-retardant ink CC98020, first cover base ink layer 141 may use black ink CC11727 because of better adhesion between CC98020 and CC 11727.
The color of the second cover bottom ink layer 142 may be different from the color of the first cover bottom ink layer 141. When the first cover bottom ink layer 141 is carved through by laser, the color of the mark can be presented as the color of the second cover bottom ink layer 142, and the second cover bottom ink layer 142 is different from the first cover bottom ink layer 141 in color, so that the mark presents clear writing. For example, when the color of the first cover bottom ink layer 141 is black, the second cover bottom ink layer 142 and the third cover bottom ink layer 143 may be both set as white ink layers, and since the contrast between black and white is relatively large, when the first cover bottom ink layer 141 is laser-engraved, it can be ensured that the engraved mark has relatively high definition. It can be understood that, only set up second lid bottom ink layer 142 to white ink layer, can be when first lid bottom ink layer 141 is carved through by laser, make the mark present the colour different with first lid bottom ink layer 141 (the colour of mark is the colour of second lid bottom ink layer 142 promptly), however, when all setting up second lid bottom ink layer 142 and third lid bottom ink layer 143 to white ink layer, the thickness of white ink layer has been increased in other words, make white ink layer's white more obvious, when first lid bottom ink layer 141 is carved through by laser, when the bottom in laser sculpture position exposes white ink layer, more obvious white can promote the definition of mark.
For example, white flame-retardant ink CC98001 may be used for both second cover base ink layer 142 and third cover base ink layer 143, and when white flame-retardant ink CC98001 is used for second cover base ink layer 142, black ink CC11729 may be used for first cover base ink layer 141, because CC11729 and CC98001 have better adhesion.
Fourth priming ink layer 144 may be a black flame retardant ink such as CC98107.
In the embodiment of the present application, the black ink with the model number CC11727, the black ink with the model number CC11729, the black flame-retardant ink with the model number CC98020, the white flame-retardant ink with the model number CC98001, and the gray ink with the model number CC10600 may all be purchased from granted ink paint (shenzhen) limited company.
The inner texture layer 122 can make the shell 10 generate light and shadow flow change, and improve the appearance expression of the shell 10. Illustratively, the inner texture layer 122 may be formed in a manner of: the side of the body 110 away from the outer texture layer 121 is coated with a light-sensitive glue, and the inner texture layer 122 with a texture structure on the surface is formed after mold imprinting and ultraviolet irradiation curing.
The optical film layer 130 can be matched with the inner texture layer 122, so that the housing 10 has different gloss changes at different angles, different textures are provided, and the appearance expressive force of the housing 10 is improved. The optical film layer 130 may include a plurality of structural layers, which cooperate with each other to achieve different visual effects through reflection, refraction, transmission, and the like. Illustratively, the plurality of structural layers may include a niobium dioxide layer, a metallic indium layer, a silicon-aluminum composite layer, and the like. The optical film layer 130 can be formed by vacuum plating, which is a film forming method that converts solid materials into gas phase substances in atomic, molecular or ionic states by physical forms such as evaporation or sputtering under vacuum conditions and then deposits the evaporated particles carrying energy onto the surface of a substrate or a part to form a film layer.
The casing 10 of the embodiment of the application is mutually supported through texture layer 122, outer texture layer 121, optics rete 130 in adopting, forms the luminous visual effect of scintillation, and when watching from different angles, casing 10 can demonstrate different flash of light effects to the very big outward appearance that has richened casing 10 promotes the product competitiveness of the electronic equipment 100 that uses this casing 10.
It is understood that the body 110 is a main structure of the housing 10 and is transparent, the body 110 may be made of a composite plastic material, for example, the body 110 may include a first transparent material layer 111 and a second transparent material layer 112 which are stacked, the first transparent material layer 111 is made of polymethyl methacrylate (PMMA), the second transparent material layer 112 is made of Polycarbonate (PC), the outer texture layer 121 may be disposed on a side of the first transparent material layer 111 facing away from the second transparent material layer 112, and the inner texture layer 122 may be disposed on a side of the second transparent material layer 112 facing away from the first transparent material layer 111. Known PMMA has the advantages of good light transmission, high hardness and the like, and simultaneously has the defects of high brittleness and the like, PC has the advantages of good flexibility and the like, and simultaneously has the defects of low hardness and the like, so that PMMA and PC can be combined together to complement each other in the aspects of light transmission, hardness, flexibility and the like, and the formed composite material has good comprehensive performance. For example, the first transparent material layer 111 (PMMA layer) and the second transparent material layer 112 (PC layer) can be formed by co-extrusion.
