Abstract
A method for making silicone rubber key includes forming the main body of key, printing letters or graphics on its top, coating with activating layer, pouring rubber latex of protecting film into mould with concave slots, putting said main body in the mould, ultraviolet radiation for solidification, demoulding, trimming, and baking. Its advantages are short production period, simple operation, beautiful appearance and low cost.
Description
The present invention relates to silicone rubber key, refer in particular to manufacture method of a kind of silicone rubber key and products thereof.
The manufacture method of at present general silicone rubber key is to offer rubber and plastic mould moulding respectively, makes both are fixed again, and its major defect is:
1, must offer separately mould to every kind of product, die cost is higher.
2, manufacture process is more numerous and diverse, and the time is longer, complicated operation, and manufacturing cost is higher.
At above-mentioned defective, the inventor has carried out studying repeatedly and putting into practice, and creates technical scheme of the present invention.
The object of the present invention is to provide that a kind of processing procedure is easy, the manufacture method of the silicone rubber key that do not need plastic mould and products thereof, reach the purpose that shortens processing procedure, saves time and reduce cost.
The object of the present invention is achieved like this: a kind of manufacture method of silicone rubber key is characterized in that: this manufacture method comprises the steps:
(1) keyboard moulding: forming press key body;
(2) be printed on literal or the figure that the end face printshop of above-mentioned keying body needs;
(3) apply active layer: on above-mentioned printed layers, apply active layer;
(4) smelting tool moulding: the corresponding above-mentioned keying body of moulding is provided with the smelting tool of chase;
(5) smelting tool injecting glue: in the chase of this smelting tool, inject glue-line, make the smelting tool moulding that is provided with the injecting glue layer;
(6) cover: the keying body of the coating active layer of above-mentioned (three) and the smelting tool moulding that is provided with the injecting glue layer that above-mentioned (five) make are covered mutually;
(7) ultraviolet ray is fixed: with ultraviolet ray above-mentioned (six) are shone, made this active layer and injecting glue layer be consolidated into one mutually;
(8) remove the moulding of smelting tool: remove this smelting tool moulding, make the keying body that the surface is provided with protective layer;
(9) remove unnecessary hardening thing: remove the surperficial unnecessary hardening thing of above-mentioned (eight) keying body, make smooth surface smooth;
(10) baking: under specific temperature, toast the regular hour, make silicone rubber key of the present invention;
The described active layer of this step (three) comprises the siloxanes that contains amidine functional group; The thickness of the described active layer of this step (three) is 10-20 μ m; The described smelting tool of this step (four) is transparent smelting tool; The bottom thickness of described chase of this step (four) and smelting tool is less than 1mm; The composition of the described injecting glue layer of this step (four) comprises polymethyl methacrylate or polyurethanes; The thickness of the described injecting glue layer of this step (four) is 1-4mm; The described ultraviolet irradiation time of this step (seven) is 30-600 second; The thickness of the described protective layer of this step (eight) is 1-4mm; The described protective layer of this step (eight) be shaped as required arbitrary shape; The unnecessary hardening thing in the described surface of this step (nine) is the hardening thing of polymethyl methacrylate or polyurethanes; The temperature of the described baking of this step (ten) is 50-80 ℃; The described stoving time of this step (ten) is 60-180 minute.
Major advantage of the present invention is:
1, do not need to offer respectively plastic cement and rubber mold, reduce die cost greatly.
2, make simply, only by apply active layer on keying body, with ultraviolet irradiation polyacrylate or polyurethane protective layer are fixed in keytop again, form through baking, process time is shorter, and is easy and simple to handle, reduces manufacturing cost greatly.
3, product of the present invention, handsome in appearance various, with low cost.
Further specify below in conjunction with preferred embodiment and accompanying drawing.
Fig. 1 is a manufacturing process flow schematic diagram of the present invention.
