Abstract
The production method of transparent key includes the following steps: using silicone rubber as raw material, adopting hot-press forming process to make it into silicone key base body, spraying the surface of said silicone key base body with transparent and non-transparent rubber-based printing ink several times and making solidification treatment, then spraying polyurethane film and soaked polyvinyl alcohol walnut wood film and making water-washing treatment, laser etching characters or pattern, then spray-coating transparent polyurethane protective film. Said invention is simple in production process, convenient for operation, and said invented product is firm in structure, soft in hand touch and beautiful in appearance.
Description
The present invention relates to the telecommunications product, refer in particular to manufacture method of a kind of water-covered type transparent key and products thereof.
Telecommunications product commonly used, divide two kinds substantially as the light-penetration key of mobile phone, beep-pager, telephone set, remote controller and sound equipment etc.: a kind of is that its external form and texture are all poor with the light-penetration key of printing opacity silicone rubber through radium-shine etching literal or image; Another kind is that with the copper silicon rubber adhesion, its external form and texture are better again, but make more complicated with plastic cement material process metal coating, and production cost is higher, and the bonding place of its plastic cement and silicone rubber is easy to generate peels off.
The inventor is at above-mentioned defective, concentrates on studies and tests, and creates technical scheme of the present invention.
Manufacture method that provides a kind of water-covered type transparent key and products thereof is provided the object of the invention, overcomes the drawback of prior art, reach external form various, soft, in conjunction with firmly, make simple purpose.
The object of the present invention is achieved like this: a kind of manufacture method of water-covered type transparent key is characterized in that this manufacture method in turn includes the following steps:
(1) with the hot-forming silicone rubber key matrix of silicone rubber;
(2) above-mentioned silicone rubber key matrix being carried out after-hardening handles;
(3) then form first photic zone through spraying or screen printing, and carry out cure process with printing opacity printing ink;
(4) then form second photic zone through screen printing, and carry out cure process with printing opacity printing ink;
(5) then form light non-transmittable layers through spraying, and carry out cure process with light tight printing ink;
(6) then form polyurethane coating through spraying, make semi-finished product with polyurethane coating;
(7) semi-finished product that above-mentioned (six) are made are soaked in and form polyvinyl alcohol walnut film in the polyvinyl alcohol walnut solution, then wash processing again, make and form polyvinyl alcohol walnut lines on this polyurethane coating;
(8) keytop of following (seven) carries out required literal of radium-shine etching or pattern, makes the inventor's water-covered type transparent key.
The temperature of the described hot-forming silicone rubber key of this step () is 150-170 ℃, and the time is 3-5 minute; The described after-hardening treatment temperature of this step (two) is 180-220 ℃, and the time is 3-5 hour; The rubber that the described printing opacity printing ink of this step (three) is printing opacity is printing ink; Described first photic zone of this step (three) is the photic zone of white; The described cure process temperature of this step (three) is 180-220 ℃, and the time is 5-15 minute; The rubber that the described printing opacity printing ink of this step (four) is printing opacity is printing ink; Described second photic zone of this step (four) is coloured photic zone; The described cure process temperature of this step (four) is 180-220 ℃, and the time is 5-15 minute; The described light tight printing ink of this step (five) is that lighttight rubber is printing ink; The described light non-transmittable layers of this step (five) is coloured light non-transmittable layers; The described cure process temperature of this step (five) is 180-220 ℃, this 5-15 of time minute; The described polyurethane coating of this step (six) is transparent polyurethane coating; The temperature of the described spraying polyurethane coating of this step (six) is 55-65 ℃, and the time is 3-7 minute; The described time that is soaked in the polyvinyl alcohol walnut solution of this step (seven) is 2-3 minute; Behind the required literal or pattern of the described radium-shine etching of this step (eight), spray transparent polyurethane coating protective layer again; This button is made with the described manufacture method of claim 1.
Major advantage of the present invention is: light-penetration key of the present invention is through repeatedly applying printing opacity or lighttight rubber is printing ink in type copper silicon rubber key surface, and cure process, apply the polyurethane resin thin layer again, again with the coating of polyvinyl alcohol walnut film water, radium-shine again etching literal or pattern, the rubber that replaces single complexion commonly used is printing ink, has various attractive in appearance, soft, the sound construction of button external form, makes effects such as simple.
The present invention is further described below in conjunction with preferred embodiment and manufacturing process flow diagram.
Fig. 1 is a manufacturing process flow schematic diagram of the present invention.
Consult Fig. 1, manufacturing process flow of the present invention in turn includes the following steps:
(1) with the hot-forming silicone button of copper silicon rubber matrix A, its hot-forming temperature is 150-170 ℃, and the time is 3-5 minute;
(2) silicone button matrix A is carried out after-hardening and handle, temperature is 200 ℃, and the time is 4 hours, makes the surface form hardened layer 1;
(3) with spraying or screen plate printing method, be the photic zone 2 that printing ink forms first white with the printing opacity rubber of white, and carried out cure process 10 minutes at 200 ℃;
(4) be printing ink with coloured printing opacity rubber then, screen printing forms second coloured photic zone 3, and carries out cure process 10 minutes at 200 ℃;
(5) the light tight rubber of following with brown is printing ink spraying light non-transmittable layers 4, and carries out cure process 10 minutes at 200 ℃; Can certainly select the light tight rubber of any color for use is printing ink;
(6) then with the transparent transparent polyurethane coating 5 of polyurethane coating spraying, temperature is 60 ℃, and the time is 5 minutes, makes semi-finished product of the present invention;
(7) then above-mentioned semi-finished product are soaked in the polyvinyl alcohol walnut solution 2-3 minute, form polyvinyl alcohol walnut film, wash processing afterwards, just on transparent polyurethane coating 5, form polyvinyl alcohol walnut lines 6;
(8) then carry out required literal of radium-shine etching or pattern 7 on the surface of (seven) button;
(9) spray transparent polyurethane coating diaphragm 8 more at last, make water-covered type transparent key of the present invention.
Because on silicone rubber key matrix A, having carried out repeatedly applying transparent or opaque rubber is printing ink, and carries out cure process respectively; Spray transparent polyurethane coating and examine wooden film with the immersion polyvinyl alcohol, combination between making mutually is very firm, do not take place to peel off mutually, increased useful life greatly, and have preferable flexibility and feel, be convenient to be processed into required different shape and color, realized sound construction, soft, effect that shape is attractive in appearance and practical.
