Description
Technical field:
The utility model relates to computer peripheral equipment product technical field, especially relates to a kind of keycap of computer 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: the strong UV photocuring of the spraying/transfer printing bottom semi-transparent lac varnish 60-solidification-spraying/transfer printing of light color light tight radium carving colored paint 40-solidification-radium carving character 41-spraying/transfer printing 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 spraying/transfer printing, 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 light tight 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 light tight product, but be also overcome recently.
Except the modes that three paintings three are roasting, Microsoft's backlight keyboard takes spraying/transfer printing bilayer to be added with the polyurethane resin of 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 fall computer, 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 fall computer, 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 computer 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 computer 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, has the square platform of upper surface and side wall; The upper surface platform localised application of keycap body has the semi-transparent coating of bottom light color; Keycap body upper surface platform without the upper surface of the semi-transparent coating of upper surface and bottom light color of the semi-transparent coating of bottom light color and side wall surperficial, be jointly coated with outer cross-linking reaction type high hardness spray coating; Outer cross-linking reaction high hardness spray coating is light tight, is added with dyestuff or pigment in it; The semi-transparent coating of bottom light color appears from the outer cross-linking reaction high hardness spray coating destroyed by laser radium carving and produces character.
Preferred as technique scheme, the coating scope of the described semi-transparent coating of bottom light color is slightly less than whole keycap body upper surface platform, in the dark ink coating that the bottom light color upper surface silk-screen of semi-transparent coating or bat printing have scope close, keycap body silk-screen or bat printing have the outer surface of the upper surface of dark ink coating and other non-silk-screens or bat printing dark ink coating area jointly to spray to be added with the cross-linking reaction type high hardness spray coating of dark dye or pigment.
Preferred as technique scheme, the coating scope of the described semi-transparent coating of bottom light color is slightly larger than the region of 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 outer cross-linking reaction high hardness spray coating is the polyurethane resin being added with curing agent.
Preferred as technique scheme, the described semi-transparent coating of bottom light color be locally silk-screen/pad-transfer printing ink, and its resin is baking-curing type.
Preferred as technique scheme, the described semi-transparent coating of bottom light color be locally silk-screen/pad-transfer printing ink, and its resin is UV light-cured type.
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) form the semi-transparent photosphere of bottom light color with silk-screen/bat printing or bat printing mode, controlled liquefaction paint consumption, reduces waste of spraying paint; (3) reduce baking processing number of times, bearing fixture can be increased the service life; 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/bat printing 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;
Fig. 4 is the profile of the utility model embodiment three;
Embodiment:
As shown in Figure 2: the keycap of backlight keyboard of the present utility model, keycap body 10 is formed by translucent or the injection mo(u)lding of high transparency plastic warp; The local of keycap body 10 upper surface platform or most of area are coated with the semi-transparent coating 30 of bottom light color in the mode of silk-screen or bat printing, the uncoated outer surface of keycap body 10 upper surface platform 11 sprays/transfer printing outer cross-linking reaction type high hardness spray coating 20 jointly with the side surface of bottom semi-transparent coating 30 upper surface of light color and side wall, light tight dyestuff 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 the bottom semi-transparent coating 30 of light color and produce character 100.
Its work flow is as follows: first, in the local of keycap body 10 upper surface or close to whole areas silk-screen/semi-transparent coating 30 of bat printing bottom light color, afterwards, baking-curing, spraying/transfer printing outer cross-linking reaction type high hardness spray coating 20, UV light source irradiation solidification up and down, radium carving produce character 100.
In addition, the semi-transparent coating 30 of bottom light color, except using the resin of baking-type, also can use the resin of print print/bat printing or transfer printing UV light curable type; Especially the mode of transfer film in film can be taked.
Example two as shown in Figure 3: have dark ink 70, the upper surface being dimensioned slightly smaller than keycap of square areas at the square areas silk-screen of semi-transparent coating 30 upper surface of bottom light color; Dark ink 70 region be dimensioned slightly smaller than bottom light color coating 30, radium carving destroys two dark ink coatings 70 and outer cross-linking reaction type high hardness spray coating 20 simultaneously, produces vacancy and forms character 100.
Embodiment shown in Fig. 4 three and embodiment two unlike, the size of dark ink coating 70 is slightly larger than the semi-transparent coating 30 of bottom light color.
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.
