Description
Technical Field
[0001] The utility model relates to the field of automobile wheel hub manufacturing, in particular to an aluminum foil sticker for automobile wheel hub multi-color overprinting process. Background Art
[0002] As people's living standards improve, the aesthetic requirements for common items in life are gradually increasing; automobile wheels occupy an important position in the appearance of automobiles; in recent years, wheels with at least two colors produced by color matching technology have become more and more popular among consumers. The existing color matching processes for producing multi-color wheels mainly include two types: spraying color matching paint after using protective tooling to block and spraying color matching paint after pasting protective stickers; the color matching process using protective tooling to block, the protective tooling is steel or tetrafluoroethylene high-temperature resistant material, and a large number of color matching protective tooling must be prepared for mass production, and each tooling can only be used with one type of wheel, which has great limitations. It needs to clean the paint residue and maintenance after using it for more than 3 times, otherwise it will be poorly protected and the two adjacent colors will be mixed. The protective tooling has defects such as high production cost, high later maintenance cost, easy deformation after long-term use, and loose protection. The color coating process (multi-color full coating process) using the protective sticker includes the following steps: (1) pre-treatment cleaning, (2) spraying primer, (3) spraying color coating, (4) sticking the protective sticker, (5) spraying the primer, (6) removing the protective sticker, (7) CNC finishing and spraying the topcoat. The steps of spraying primer, spraying the color coating and spraying the primer all include high temperature (140-200℃) baking.
[0003] The protective stickers used in the prior art are high temperature resistant stickers or high temperature resistant plastic (PET) films, which have the same shape as the part on the wheel hub that needs to be shielded and protected, and have an area 1-1.1 times that of the part on the wheel hub that needs to be shielded and protected. Since the protective stickers are soft and easy to bend, when they are pasted on the grooves or windows in the hollowed-out parts of the wheel hub for protection, the protective stickers have poor maneuverability, the edges are easily adhered to the non-relative position of the wheel hub, and the alignment between the protective stickers and the grooves or windows on the wheel hub is poor, making the pasting operation difficult, time-consuming and labor-intensive.

H24 aluminum foil; the buffer adhesive layer 4 and the fixed adhesive layer 6 are made of high temperature resistant double-sided adhesive tape. In this embodiment, the buffer adhesive layer and the fixed adhesive layer are made of adhesive layers of high temperature resistant double-sided tape arranged in parallel without interruption; the wheel hub compliant adhesive layer 7 is made of high temperature resistant silicone tape. In this embodiment, the wheel hub compliant adhesive layer 7 is made of high temperature resistant green silicone tape including silicone and polyester (PET) film arranged in parallel without interruption, and the release film layer 1 is made of fluoroplastic release film. The right side of the H18 aluminum foil is bonded and fixed to the left side of the H24 aluminum foil through high temperature resistant double-sided tape, and the right side of the H24 aluminum foil is bonded and fixed to the polyester (PET) film on the left side of the green silicone tape through high temperature resistant double-sided tape. The silicone on the right side of the green silicone tape is bonded and adhered to the fluoroplastic release film. The high temperature mentioned in the present invention refers to the maximum baking temperature of the multi-color color matching process of the wheel hub, which is 200°C in this embodiment.
[0020] The shapes of the hard aluminum foil layer, buffer adhesive layer, semi-hard aluminum foil layer, fixed adhesive layer and wheel hub conforming adhesive layer described in this embodiment are the same as the part that needs to be shielded and protected on the automobile wheel hub, and the area is 1-1.1 times; preferably 1.02-1.05 times. The release film layer is square; the area of the release film layer is 1.3 times the part that needs to be shielded and protected on the automobile wheel hub, which is convenient for peeling and sticking back during use.
[0021] Furthermore, a peeling ear 3 is provided on one side of the hard aluminum foil layer, buffer adhesive layer, semi-hard aluminum foil layer, fixed adhesive layer and hub conforming adhesive layer described in this embodiment; the peeling ear 3 facilitates the bonding and peeling operations during use.
[0022] When the utility model is used, the hard aluminum foil layer, the buffer adhesive layer, the semi-hard aluminum foil layer, the fixed adhesive layer and the wheel hub conforming adhesive layer are peeled off from the release film layer as a whole, aligned with the sprayed color coating area on the automobile wheel hub that needs to be shielded and protected, and the wheel hub conforming adhesive layer is used to stick to the automobile wheel hub; after being used once in the automobile wheel hub multi-color coating process, it is peeled off from the automobile wheel hub and pasted back on the release film layer for next use; until the quality is reduced to the point that it cannot be used.
[0023] Due to the arrangement of the hard aluminum foil layer and the semi-hard aluminum foil layer, the utility model has a stable overall shape, and is not easy to wrinkle or bend during pasting in the groove or window of the hollow part of the wheel hub. The edge can be accurately aligned with the pasting position corresponding to the wheel hub, which is convenient for accurate pasting of the shape, and is not easy to stick to the wheel hub at the edge when the shape and position are not aligned, which is convenient for control, saving time and effort. The buffer adhesive layer between the hard aluminum foil layer and the semi-hard aluminum foil layer can play a flexible buffer connection. The coordinated use of the three layers of materials meets the requirements of product hardness and flexibility, so that the aluminum foil sticker will not become hardened significantly after high-temperature baking under the premise of being stable in overall shape and not easy to bend or wrinkle. During the research and development test, it was found that the hard aluminum foil layer with a single layer exceeding 2mm hardened and decreased in flexibility after high-temperature baking, and was prone to plastic deformation during use; the hard aluminum foil layer with a single layer below 1.5mm is soft, low in hardness, poor in flexibility, and easily becomes brittle and easy to tear due to the hardening of the paint, and has poor reusability, and can be used twice at most. The invention is not prone to plastic deformation during use, and the wheel hub adhesion layer is closely attached to the outer surface of the automobile wheel hub during repeated use, and is not prone to gaps. When three layers of color coating paint are sprayed on the outside of the H18 aluminum foil layer (repeatedly used three times in the color coating process), the whole will not become brittle due to the hardening of the paint, and is not prone to tearing and damage. It can be reused 4-5 times, reducing the production cost of multi-color wheels.
