Abstract
The utility model discloses a kind of keycap of low-cost backlight keyboard, it has the projection source of keycap body and bottom, and keycap body is formed by translucent or the injection mo(u)lding of high transparency plastic warp; The outer surface of keycap body is coated with the bottom light color coating of baking volatile-type, the uncoated upper surface of keycap body and bottom light color coating upper surface spray the cross-linking reaction type high hardness spray coating being added with black dyes or pigment jointly, and bottom light color coating appears from the outer cross-linking reaction type high hardness spray coating destroyed by laser radium carving and produces character.The beneficial effects of the utility model are: (1) its replace traditional three with two painting processing procedure and be coated with processing procedures, significantly can reduce production cost; (2) reduce baking processing number of times, bearing fixture can be increased the service life, reduce costs further; (3) its material and progress all comparatively environmental protection, can reduce environmental pollution.
Description
Technical field:
The utility model relates to computer peripheral equipment product technical field, especially relates to a kind of keycap of backlight keyboard.
Background technology:
Many desktops and notebook all can use the keycap coating of backlight keyboard, its keycap takes three layers of coating way to be formed, as shown in Figure 1, its work flow is: sprayed layer undercoat light colour paint 60-solidification-spray black radium carving colored paint 40-solidification-radium carving character 41-sprays the strong UV photocuring of UV light-cured resin paint 50-; The process of repetition like this causes flow process very long, and cost is very high; In addition, cause environmental issue, need a large amount of solvent to cause a discharge difficult problem.
All the time, many paint manufacturers attempt mill base to incorporate UV light-cured resin paint, as long as so once spray, but because pigment Absorbable rod ultraviolet light, affect the light absorption of light trigger, and pigment also can scattering ultraviolet light, ultraviolet light is made to be difficult to arrive the bottom of coating, especially black pigment strong absorption ultraviolet light, the light transmittance of coating declines, affect the reaction between bottom coupling agent and resin, reduce the adhesion between film and base material, thus adhesive force declines by a big margin, UV light-cured resin paint up to date containing pigment just obtains larger improvement, although at the application still rather unstable of black product, but be also overcome recently,
Except the modes that three paintings three are roasting, Microsoft's backlight keyboard is taked to spray the double-deck polyurethane resin being added with curing agent; But because needing high temperature to toast for a long time, keycap can be caused to be out of shape, therefore to take two painting support to reduce costs, high temperature also must be avoided to toast for a long time, meet IT industry again to wear-resisting requirement, so suitable structure and material technology must be developed in addition.Then not only can reduce costs, and can environmental pollution be reduced.
Utility model content:
The purpose of this utility model is just the weak point that exists for prior art and provides a kind of keycap of new low-cost backlight keyboard newly, production cost is low, environmental pollution is little feature that it has.
For achieving the above object, the keycap of a kind of low-cost backlight keyboard of the present utility model, has the projection source of keycap body and bottom, and keycap body is formed by translucent or the injection mo(u)lding of high transparency plastic warp; The outer surface of keycap body is coated with the bottom light color coating of toasting volatile-type in the mode of local silk-screen or all sprayings, and the uncoated upper surface of keycap body and bottom light color coating upper surface spray cross-linking reaction type high hardness spray coating jointly; Bottom light color coating appears from the outer cross-linking reaction type high hardness spray coating destroyed by laser radium carving and produces character.
Preferred as technique scheme, described outer reaction high hardness spray coating is the UV light-cured resin being added with initator, injects row crosslinking curing through UV illumination.
Preferred as technique scheme, described cross-linking reaction high hardness spray coating is the polyurethane resin being added with curing agent.
Preferred as technique scheme, described bottom light color coating be locally ink for screen printing, and its base material is baking-curing plastic resin or acrylic resin.
Preferred as technique scheme, described bottom light color coating is spray and the acrylic resin solidified.
The beneficial effects of the utility model are: 1) it replaces three traditional painting processing procedures with two painting processing procedure, significantly can reduce production cost; (2) silk-screen or bat printing mode can form bottom bleached bed, controlled liquefaction paint consumption, reduce waste of spraying paint; (3) reduce baking processing number of times, bearing fixture can be increased the service life, reduce costs further; Current three are coated with the bearing fixtures of modes can only use three times, if make two paintings into and priming paint adopts silk-screen from the mode of dry ink, then can use nine times; (4) its material and progress all comparatively environmental protection, can reduce environmental pollution.
Accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the utility model is described further:
Fig. 1 is the profile of the keycap of existing backlight keyboard;
Fig. 2 is the profile of the utility model embodiment one;
Fig. 3 is the profile of the utility model embodiment two.
Embodiment:
As shown in Figure 2: the keycap of backlight keyboard of the present utility model, have the projection source of keycap body 10 and bottom, keycap body 10 is formed by translucent or the injection mo(u)lding of high transparency plastic warp; The outer surface of keycap body 10 is coated with the bottom light color coating 30 of baking volatile-type in the mode of spraying, the uncoated upper surface 11 of keycap body 10 and bottom light color coating 30 upper surface spray cross-linking reaction type high hardness spray coating 20 jointly; Be added with black dyes or pigment in cross-linking reaction high hardness spray coating 20, bottom light color coating 30 appears from the outer cross-linking reaction type high hardness spray coating 20 destroyed by laser radium carving and produces character 21.
Its work flow is as follows: first, keycap body 10 outer surface entire area sprayed layer undercoat light color coating 30, afterwards, baking-curing, spray outer cross-linking reaction type high hardness spray coating 20, UV solidification, radium carving produce character 21.Wherein, when spraying outer cross-linking reaction type high hardness spray coating 20, UV photocuring continuous tunnel furnace all has UV light source to irradiate from both up and down up and down simultaneously.
Except UV resin.Also the polyurethane resin being added with curing agent can be used.
In the embodiment shown in fig. 3, the local of keycap body 10 upper surface or have bottom light color coating 30 close to whole area silk-screens, the uncoated outer surface of keycap body 10 11 sprays outer cross-linking reaction type high hardness spray coating 20 jointly with bottom light color coating 30 upper surface, black dyes or pigment is added with in outer cross-linking reaction type high hardness spray coating 20, destroy outer cross-linking reaction type high hardness spray coating 20 with laser radium carving, appear bottom light color coating 30 and produce character 21.
Its work flow is as follows: first, in the local of keycap body 10 upper surface or close to whole area silk-screen bottoms light color coating 30, afterwards, baking-curing, spray outer cross-linking reaction type high hardness spray coating 20, up and down UV light source irradiation solidification, radium carving produce character 21.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
