Description

Technical Field

[0001] The present application relates to the technical field of vehicle parts, and in particular to a vehicle decorative molding and a manufacturing method thereof. Background Art

[0002] At present, the signs or logos (Logos for short) at the rear of the car are generally made of plastic parts. After the plastic parts are electroplated and treated with a surface treatment, they are pasted on the sheet metal at the rear end in the form of tape to form a Logo. Due to the thickness of the plastic parts themselves, they always protrude on the flat sheet metal surface after pasting, and the protrusion is generally about 2mm. The disadvantage brought about by this is that the shape lacks integrity and there is a noticeable concave and convex feeling when touched. Some manufacturers first make the tail area where the Logo is pasted into a groove and then paste the Logo in the groove to achieve the effect of the Logo and the surrounding large surface being integrated, but the disadvantage is that the Logo installation requires very high positioning accuracy to match the surrounding parts. In addition, due to the existence of the groove, the overall shape cannot achieve a Logo effect close to the plane. In addition, there are some Logos on the market that are usually installed on the bumper, but their forming process is relatively complicated. Generally, a silver processing process of two-color injection molding plus evaporation plating is used: first, a transparent outer plate is injection molded, then a black inner plate is injection molded, and then a metal layer is evaporated and plated on the back of the part. This Logo needs to be installed separately on the bumper, and there is also a matching gap around it. Summary of the invention

[0003] In view of this, the main purpose of the present application is to provide a vehicle decorative molded body and a method for making the same, so as to obtain a decorative molded body containing a logo that has no obvious protrusions or grooves and is close to a plane, thereby improving the aesthetics of the overall shape and reducing the assembly steps.

[0027] A first aspect of the present invention provides a vehicle decorative molding, comprising:

[0028] A vehicle rear windshield having a first surface facing the outside of the vehicle and a second surface located on the other side opposite to the first surface;

[0029] The label film layer is stacked on the first surface of the rear windshield of the vehicle.

[0030] In the present invention, the nameplate film layer is located in a partial area of ​​the first surface. In practical applications, its specific position and size are determined according to the nameplate style. The specific position is not limited. For example, the nameplate film layer can be located in the upper, middle, lower, or peripheral area of ​​the first surface.

[0031] Preferably, the thickness of the nameplate film layer is 50-70 μm, for example 50 μm, 55 μm, 60 μm, 65 μm, 70 μm or other values ​​within this range. The thickness of the nameplate film layer is extremely thin. When compared with other areas of the first surface of the rear windshield of the vehicle without the nameplate film layer, there is no obvious difference in appearance and feel, and they are almost in the same plane.

[0032] Preferably, the vehicle decorative molding further comprises: a black edge film layer, which is superimposed on the peripheral area of ​​the second surface of the vehicle rear windshield. Conventional vehicle rear windshields are generally provided with black edge film layers around them, that is, the periphery is a black area and the middle is a transparent area, and the black area plays other functional roles such as aesthetics, adhesion or shielding.

[0033] Preferably, in order to increase the contrast and make the logo more obvious, the position of the sign film layer may correspond to the position of the black edge film layer, that is, in some examples, the sign film layer is provided in the peripheral area of ​​the first surface of the rear windshield of the vehicle.

[0034] Preferably, in order to increase the contrast and make the logo more obvious, the nameplate film layer may be a colored ink layer, such as a bright silver ink layer. That is, in some examples, a bright silver nameplate film layer is provided in the peripheral area of ​​the first surface of the rear windshield of the vehicle, so that the logo is more conspicuous against the background of the black-bordered film layer in the peripheral area of ​​the second surface. Further preferably, according to automobile manufacturing and user habits, a bright silver nameplate film layer may be provided in the middle area of ​​the lower periphery of the first surface of the rear windshield of the vehicle.

[0035] Preferably, in order to increase privacy, the rear windshield of the vehicle is preferably a gray privacy tempered windshield.

[0036] A second aspect of the present invention provides a method for manufacturing a vehicle decorative molding, comprising the following steps:

[0037] Providing a vehicle rear windshield glass original sheet having a first surface and a second surface;

[0038] The label ink is printed on the first surface of the vehicle rear windshield glass original sheet and then sintered to obtain a label film layer.

[0039] In the traditional production process of tempered windshield glass, the main production process includes cutting, breaking, grinding, washing and drying of the glass substrate to obtain the original glass sheet, then black edge printing, drying and bending, rapid cooling, and finally packaging. The production method of the present invention combines the production process of windshield glass and adds two processing steps before black edge printing, namely: printing the label ink on the first surface of the original glass sheet, and then sintering to obtain the label film layer. Preferably, it can be understood that in order to improve the printing quality and the bonding strength between the label film layer and the original glass sheet, it is preferred to use the original glass sheet after washing and drying.

[0040] In the present invention, the manufacturing method further comprises: printing black edge ink on the second surface of the original sheet of the rear windshield of the vehicle to obtain a black edge film layer. That is, after obtaining the label film layer, the present invention continues to carry out subsequent production processes of the windshield, such as: printing black edge ink, drying and bending, rapid cooling (setting), and finally packaging. Preferably, the printing of black edge ink adopts screen printing or steel screen printing, preferably steel screen printing, and the specific printing parameters refer to the conventional process in the field.

[0041] In a specific example, the black ink includes glass pigment, varnish, additives, etc. The glass pigment is mainly low-melting point glass powder (such as Bi2O3, B2O3, ZnO, SiO2, etc., accounting for about 85%), inorganic pigments (such as Cu, Fe and other oxides, accounting for about 10%) and additives (sulfide, accounting for about 5%); varnish is selected from polymer resin; additives include organic solvents, etc.

[0042] In the present invention, the components of the label ink include, by mass percentage: 10%-20% (E,E)-2,4-hexadienoic acid, 13%-17% tetraisopropoxytitanium and 5%-15% metal oxides, and the rest is cooked rosin, wherein the metal oxides include but are not limited to one or more of metal oxides such as Fe and Ag. The label ink using the above components has better heat resistance, and is not easy to volatilize even at a high temperature of 600°C, which better meets the high-temperature bending requirements of the rear windshield; in addition, the label ink is a color-changing ink, which is pink in the initial printing and becomes bright silver after subsequent sintering, and has a mirror reflection effect.

[0043] Preferably, the printing of the label ink on the first surface of the vehicle rear windshield original sheet is performed by screen printing or steel screen printing, preferably steel screen printing, and the specific printing parameters refer to conventional processes in the art.

[0044] Preferably, the sintering conditions include: a sintering temperature of 270-320°C and a time of 5-10 minutes. Preferably, the sintering temperature is 300°C and the sintering time is 8 minutes. In the production process of traditional tempered windshields, the black border is generally printed and then dried at a temperature of about 200°C before the glass is formed. The present invention adds a sintering step for the sign ink, with a high sintering temperature and a long duration, so that a clear and firm logo is obtained.

[0045] The following embodiments are used to illustrate the vehicle decorative molding and the manufacturing method thereof of the present application.

[0046] Example 1

[0047] like Figure 1 As shown, a vehicle decorative molding comprises:

[0048] A rear windshield glass 10 of an automobile, comprising a first surface 11 facing the outside of the vehicle and a second surface 12 located on the other side opposite to the first surface 11;

[0049] The label film layer 20 is stacked on the middle transparent area of ​​the first surface 11 of the rear windshield of the vehicle.

[0050] In this embodiment, the rear windshield 10 of the automobile is a gray privacy tempered windshield (thickness 4.0 mm). The thickness of the label film layer is 60 μm, and the color of the label film layer is bright silver.

[0051] The method for preparing the vehicle decorative formed body of this embodiment includes:

[0052] In the production process of tempered windshield glass, the glass substrate is initially cut, broken and ground, and then sent to a dust-free workshop for washing and drying to obtain the original glass sheet. Subsequently, a steel screen is used to print the label ink in the middle transparent area of ​​the first surface of the original glass sheet, and the required shape is printed on the first surface of the original glass sheet, and then sintered at a temperature of 300°C and a sintering time of 8 minutes to form a bright silver logo with a thickness of 60μm. Among them, by mass percentage, the label ink is 12.3wt% of (E,E)-2,4-hexadienoic acid, 61.5wt% of cooked rosin, 15.7wt% of tetraisopropoxy titanium, 3wt% of iron oxide, and 7.5wt% of silver oxide. The above components can be obtained from commercial channels.

[0053] Example 2

[0054] like Figure 2 As shown, a vehicle decorative molding comprises:

[0055] A rear windshield glass 10 of an automobile, comprising a first surface 11 facing the outside of the vehicle and a second surface 12 located on the other side opposite to the first surface 11;

[0056] A label film layer 20, which is superimposed on the middle area of ​​the lower periphery of the first surface 11 of the rear windshield of the vehicle;

[0057] The black edge film layer 30 is stacked on the peripheral area of ​​the second surface 12 of the vehicle windshield.

[0058] In this embodiment, the rear windshield 10 of the automobile is a gray privacy tempered windshield (thickness 4.0 mm). The thickness of the label film layer is 70 μm, the thickness of the black edge film layer is 100 μm, and the color of the label film layer is bright silver.

[0059] The method for manufacturing the vehicle decorative molding in this embodiment includes the following steps:

[0060] In the production process of tempered windshield glass, the glass substrate is cut, bent and ground in the initial stage, and then sent to the dust-free workshop for washing and drying to obtain the original glass sheet. Then, the steel screen is used to print the label ink in the middle area around the lower part of the first surface of the original glass sheet, and the required shape is printed on the first surface of the original glass sheet. Then, it is sintered at a temperature of 320°C and a sintering time of 5 minutes to form a bright silver logo. Then, it leaves the dust-free workshop and screen prints the black edge ink on the second surface of the original glass sheet to obtain a black edge film layer, which is then dried at 200°C. After drying, it enters the heating and bending process at a bending temperature of 560°C, followed by rapid cooling and finally packaging.

[0061] Among them, calculated by mass percentage, the sign ink is 15.3wt.% of (E,E)-2,4-hexadienoic acid, 54.8wt.% of cooked rosin, 16wt.% of tetraisopropoxy titanium, 2.6wt.% of iron oxide, and 11.3wt.% of silver oxide; the black edge ink includes 85wt.% of glass pigment, 10wt.% of varnish and 5wt.% of organic solvent; the black edge ink is a conventional black ink on the market.

[0062] Example 3

[0063] Similar to Example 2, except that the sintering conditions are: sintering temperature is 270° C., time is 10 minutes, and a bright silver Logo with a thickness of 50 μm is obtained.

[0064] Example 4

[0065] Similar to Example 2, except that the sintering conditions are: sintering temperature is 250°C, time is 8 minutes, and the obtained bright silver logo, due to the low sintering temperature, the ink is not volatilized completely, which may cause color difference in the local color of the logo, resulting in redness of the surface.

[0066] Obviously, the above embodiments of the present application are merely examples for clearly illustrating the present application, and are not intended to limit the implementation methods of the present application. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all implementation methods here.
