Abstract
The present invention relates to an integrally formed hard head rubber key, and a manufacture method and an application thereof. A hard head is injected and formed by thermosetting resin, such as epoxy resin, acrylate copolymer resin, polyamido urethane resin, etc. Then, silicone rubber and the hard head are pressed in a hot way and are integrally formed. The integrally formed hard head rubber key has the characteristics of scientific sorting, hardiness, firmness, various shapes and simple manufacturing technique, and is suitable for keys of computers, telephones, voice dictionaries, etc.
Description
The present invention relates to the process technology of button, refer in particular to the manufacture method of integrated hard head rubber key.
Normally used hard head rubber key is not an integrated formed structure, its processing method is earlier with general plastic cement material such as polycarbonate resin, acrylic resin, styrene and copolymer resins thereof etc., inject plastic mould moulding hard and press key head, and then rubber fitted with adhesive, re-use the processing of epoxy points glue.This plastic press key applying rubber structure in use is easy to generate the phenomenon of separation; The used plastic mould expense of injection moulding has costliness, the manufacturing process complexity, and manufacturing expense is higher; Put glue processing on the key head in molded good pressing, can only make single shape, can not reach the moulding of curved surface or arc with client's designing requirement.
At defective of the prior art, the inventor studies intensively exploitation, creates technical scheme of the present invention.
The object of the present invention is to provide the manufacture method of integrated hard head rubber key, the improvement traditional product is easy to generate the defective of separation with applying method, improves product efficacy.
The object of the present invention is achieved like this: a kind of hard head rubber key, comprise hard head and rubber key, it is characterized in that described hard head and the rubber key structure that is formed in one, this hard head is that thermoset injection molding forms, and this thermosetting resin comprises epoxy resin, acrylic copolymer resin or polyurethane resin; This rubber key is a silastic press key; This button is provided with literal or figure.
This manufacture method comprises: (one) selects for use thermosetting resin to comprise that epoxy resin, acrylic copolymer resin or polyurethane resin inject mould thermoset forming hard head, and temperature is 100-180 ℃, and the time is 2-15 minute; (2) liquid state or solid state si rubber and described hard head hot pressing is one-body molded, temperature is 100-180 ℃, and the time is 2-15 minute, makes hard head rubber key; (3) printing or engraving character or figure on described button.
Described epoxy resin comprises:
Wherein n is 0～5,
Acrylic copolymer resin comprises: the copolymer resins of the phthalic acid diacrylate of an ortho position or a position and acrylate, acrylic methacrylate, 2 one hydroxyethyl meth acrylates.
Described (three) engraving character or figure on button comprises earlier uses radium-shine technology engraving character or figure again with titanium, chromium, gold, vacuum coating.
This button is applicable to the button of computer, telephone set, voice dictionary.
Major advantage of the present invention comprises:
1, integrated hard head rubber key of the present invention have the science of selecting materials, solid firmly, the characteristics of various shapes.
2, to have technology simple, with low cost for manufacture method of the present invention.
3, product of the present invention is suitable for the button of computer, telephone set, mobile telephone, speakerphone, voice dictionary etc.
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is the schematic diagram of hard head rubber key of the present invention.
Fig. 2 is the schematic diagram of the positive printing of hard head rubber key of the present invention.
Fig. 3 is the laser carved schematic diagram of hard head rubber key of the present invention.
Consult Fig. 1, hard head rubber key of the present invention comprises one hot-forming hard head 1 and silastic press key 2, this hard head 1 is injection molded with thermoset synthetic resin, and the thermosetting resin of selecting for use comprises epoxy resin, phthalic acid diacrylate-acrylic copolymer resin or polyurethane resin etc.This copper silicon rubber key 2 comprises the fluid silicone rubber or the solid-state pressing mold silicon rubber of ejaculation, and above-mentioned thermosetting resin and liquid state or solid state si rubber have good adhesive effect, and is middle without any need for binding agent, has the firm characteristics of bonding.
Manufacture method of the present invention comprises: at first above-mentioned thermosetting resin is put into glue-injection machine, regulating viscosity is 450 ± 50 centipoises, quantitatively injects in the hard head mould, and regulating temperature is 100～150 ℃, and the time is 2-10 minute curing molding hard head 1; Subsequently the hard head 1 of liquid state or solid silicon glue glue and above-mentioned curing molding is injected or moulded section, its temperature is 100-150 ℃, time is 2～10 minutes, make the integrated hard head rubber key that comprises hard head 1 and silastic press key 2, it is simple to have manufacturing process, in conjunction with firm characteristics.
Consult Fig. 2 and Fig. 3, the button that said method is made can print or Carving Machining, for example uses coloured font of screen printing or figure 3 (as Fig. 2); Also can use vacuum coating to plate metal films 4 such as one deck titanium, chromium, gold earlier, use laser engraving technology engraving character or figure 5 (as Fig. 3) again.This printing, vacuum coating and engraving process are prior art, so do not describe in detail.
Claims (5)
