Detailed Description
The advantages and features of the present invention and methods of accomplishing the same will be understood more readily by reference to the following detailed description of exemplary embodiments and accompanying drawings. This invention may, however, be embodied in different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Referring to fig. 1 and fig. 2 together, fig. 1 is a flow chart of forming a key cap structure according to the present invention; FIG. 2 is a schematic diagram of a key cap structure forming process according to the present invention, and the key cap structure provided by the present invention can be applied to keys of various electronic devices. First, a key cap 10 is provided (step S101), and in step S101, the key cap 10 has an upper surface 101 and a lower surface 102 (as shown in fig. 2 (i)). The material of the key cap 10 may be, but not limited to, ABS (acrylonitrile butadiene styrene).
Next, the coating material P is disposed on the upper surface 101 of the key cap 10 (step S102), and in step S102, the coating material P is disposed on the upper surface 101 of the key cap 10 by using a spray gun, such as a manual spray gun or an automatic spray gun (see (ii) of FIG. 2). Wherein, the coating P can be a UV coating or a PU coating. In the present embodiment, the UV coating material includes 50 to 80 parts by weight of an oligomer (oligomer) and 20 to 50 parts by weight of a monomer (monomer), and the oligomer includes at least one of epoxy acrylates (epoxyacrylates), urethane acrylates (PUAs), polyester acrylates (polyester acrylates), polyether acrylates (polyether acrylates), amino-modified acrylates (amino acrylates), and acrylates (acrylic esters); the monomer comprises at least one of polyether compound and alkoxy compound. In addition, in order to improve the curing efficiency of the UV coating, 0 to 20 parts by weight of a photoinitiator (photo initiator), such as a radical type photoinitiator or a cationic type photoinitiator, may be further added. Optionally, 0 to 20 parts by weight of an additive for improving the performance of the UV coating may be added, wherein the additive comprises at least one of a leveling agent, a wetting agent, a fogging agent, an adhesion promoter, a rheological agent, a stabilizer, a pigment and a filler. Or a solvent may be selectively added in an amount of 0 to 20 parts by weight, the solvent being used to adjust the concentration of the UV paint such that the UV paint generates different viscosity or fluidity.
The PU coating comprises 40-80 parts by weight of a main agent, 1-20 parts by weight of a curing agent (hardner) and 10-80 parts by weight of a solvent. Wherein the main agent mainly comprises polyol (polyatomic alcohol), and the component of the polyol comprises at least one of polyester polyol (polyester polyol), polyether polyol (polyether polyol) and other functional group polyol. The curing agent comprises at least one of monoisocyanate (isocyanates), diisocyanate (di-isocyanate) and polyisocyanate (such as TDI, MDl or PAPI). Optionally, 0-20 parts by weight of additives may be added, wherein the additives may include at least one of cross-linking agent, leveling agent, wetting agent, fogging agent, adhesion promoter, rheological agent, stabilizer, pigment and filler.
Then, curing the coating P to form a single coating layer 11 on the upper surface 101 of the key cap 10 (step S103), in step S103, baking the coating P disposed on the upper surface 101 by ultraviolet UV irradiation or a heat source h (as shown in (iii) of fig. 2), for example, if the coating P is a UV coating, curing the coating P disposed on the upper surface 101 of the key cap 10 by ultraviolet UV irradiation, in a preferred embodiment, when the coating P is irradiated by ultraviolet UV, baking at a temperature of 20-80 ℃ at the same time to volatilize a solvent in the UV coating; if the coating P is PU coating, the coating P disposed on the upper surface 101 of the key cap 10 can be cured by baking with a heat source h, and in a preferred embodiment, the temperature of the heat source h is between 50 ℃ and 100 ℃. Thus, after the coating P is cured, the single coating layer 11 can be formed on the upper surface 101 of the key cap 10 without forming an adhesion-improving primer layer on the upper surface 101 in advance. In a preferred embodiment, the thickness of the single coating layer 11 is between 10 μm and 50 μm.
finally, a hollow pattern 111 is formed on the single coating 11 (step S104), in step S104, the single coating 11 is cut and engraved by the laser generated by the laser cutting device L (as shown in fig. 2 (iv)), so as to form the hollow pattern 111 on the single coating 11, and the hollow pattern 111 is used for forming characters or symbols of the key cap structure. In the present embodiment, the hollow-out pattern 111 penetrates the single coating 11, so that the color of the keycap 10 can be exposed in the hollow-out pattern 111. Although the present invention only proposes the embodiment in which the hollow-out pattern 111 penetrates through the single coating layer 11, in practical applications, the hollow-out pattern 111 may be formed only on the surface of the single coating layer 11 without penetrating through the single coating layer 11, and then different pigments are sprayed in the hollow-out pattern 111 to form different colors for improving the recognition degree of the characters or symbols of the key cap structure.
Compared with the prior art, the key cap structure provided by the invention only has a single-layer structure, and a primer layer for improving the adhesion between the primer layer and the protective coating layer is not required to be formed on the surface of the key cap, so that the key cap is simpler to manufacture, the thickness of the key cap structure is reduced, and the overall thickness of the keyboard can be effectively reduced. The single coating provided by the invention has good hardness and wear resistance, and can be directly subjected to laser engraving on the single coating so as to further form characters or symbols of a keycap structure; therefore, the present invention is a creation with great industrial value.
The present invention may be modified in various ways by those skilled in the art without departing from the scope of the appended claims.
