System is made excessively, does not appeal to refined taste, and it is dominant luminous (i.e. not luminous also to clearly see using text that there are also fraction electric toothbrushes
Text) form, however the cooked mode of essentially integral type easily causes whole branch if process goes wrong or careless mistake
Electronic brush is scrapped, dangerous.
Summary of the invention
The purpose of the present invention is being directed to above-mentioned deficiency in the prior art, a kind of processing risk spreading, recessive luminous is provided
Electric toothbrush housings manufacturing process.
The purpose of the present invention is achieved through the following technical solutions:
A kind of manufacturing process of electric toothbrush housings, electric toothbrush housings are equipped with transparent decorative article, the manufacturing process packet
Include following steps:
(1) it sprays: spraying shading light oil reservoir in the front of the transparent decorative article or the back side；
(2) laser carving: shape needed for being gone out shading light oil reservoir hollow out using laser laser carving；
(3) it is electroplated: in one layer of metal layer of front vacuum plating or metal oxide layer of the transparent decorative article；
(4) it is molded: the injection moulded clear flexible glue layer on the source region of power toothbrush handle；
(5) assemble: by the transparent decorative article assembly on the transparent flexible glue layer, the back side of the transparent decorative article with
The transparent flexible glue layer fitting.
The manufacture of electric toothbrush housings is divided into two parts, first is that spray-laser carving-plating to transparent decorative article, two
It is to be molded to power toothbrush handle, then the two is assembled together again, realize processing risk spreading, it is wrong reduces processing
Misquote the cost depletions of hair；The shading for non-light display area domain is realized by spraying-laser carving, and laser laser carving portrays exquisiteness, convex
The aesthetic feeling of aobvious electric toothbrush housings, and the metal layer or metal oxide layer being electroplated stop the entrance of ambient, realize hidden
Property shine, the figure or text of laser carving only can be just seen clearly that when toothbrush handle light source luminescent, more can be consumer
Bring pleasantly surprised, the transparent flexible glue layer of injection molding is conducive to the assembly of transparent decorative article, and the light that transparent flexible glue layer can issue light source
It is scattered reduction, keeps lighting effects more evenly soft.
It wherein, further include that step S1 air brushing and/or step S2 spray gloss oil after the step (3),
The step S1 air brushing is partial region or whole region air brushing on the metal layer or metal oxide layer
Text or pattern；
The step S2 spraying gloss oil is one layer of UV water-based gloss oil of front spraying in the transparent decorative article.Step S1 spray
The figure translucidus drawn is extremely strong, has substantially no effect on the illumination effect of electric toothbrush housings, and increases the color of electric toothbrush housings
Coloured silk sense；And shell feel can be enhanced in the UV water-based gloss oil of step S2 spraying, protects interior metal layer or metal oxide layer not
Corroded, and electric toothbrush has the apparatus directly contacted as with body cavity, face, security requirement is high, and aqueous UV
Gloss oil toxicity is minimum, can be with effective protection human health.
Wherein, the UV water-based gloss oil is made of the raw material of following parts by weight:
30-50 parts of prepolymer
30-90 parts of monomer
4-6 parts of photoinitiator
1-2 parts of damage resistant auxiliary agent
Organic-silicon-modified levelling agent 1-2 parts
1-2 parts of silane coupling agent
10-20 parts of solvent
Wherein, the prepolymer be aqueous polyurethane acrylate oligomer and waterborne epoxy acrylate oligomer extremely
Few one kind, the monomer are at least two of TPGDA, EOEOEA, PO3-TMPTA, PEGDA, and the photoinitiator is light-initiated
At least two of agent 184,907,1173, the scratch resistance auxiliary agent are at least one of organic wax, polyethylene micropowder, the solvent
The mixture mixed for water with ethyl alcohol with arbitrary proportion
UV water-based gloss oil of the invention has scratch resistance, and adhesive force is strong, minimum to human toxicity, is present invention process
The preferred embodiment of the power toothbrush handle gloss oil prepared.This formula prepolymer determines the main character after gloss oil solidifies,
The main function that monomer plays is the viscosity for adjusting this formula system, is adjusted to gloss oil property, and prepolymer and monomer need
The adhesive force of this formula gloss oil could preferably be strengthened by carrying out certain limited proportion, while scratch resistance auxiliary agent is added and enhances light
The scratch resistance of oil, the defects of preventing the sharp objects such as nail from leaving scratch under gloss oil.
Further, the prepolymer is oligomeric by aqueous polyurethane acrylate oligomer and waterborne epoxy acrylate
Object is mixed by weight the ratio of 1-3:1, and the monomer is by TPGDA, PO3- TMPTA and PEGDA are by weight 2:3:1's
Ratio mixes, and the weight ratio of the monomer and prepolymer is 1.5:1, the photoinitiator by photoinitiator 184,907,
The ratio of 1173 1:1:1 by weight mixes, and the solvent is made of water and ethyl alcohol by weight the ratio mixing of 1:1.
Light oil reservoir after aqueous polyurethane acrylate oligomer solidifies with respect to waterborne epoxy acrylate oligomer has
Better flexibility, wearability, water resistance, but the ability to cure of epoxy resin is stronger, in conjunction with the advantage and electric tooth of the two
The demand of brush handle is 1-3:1 to the preferred mixed proportion that the selection of prepolymer is made, and more preferably ratio is 2:1；
TPGDA and PO3- TMPTA contains propoxyl group, increases the flexibility of gloss oil after solidifying, PO3- TMPTA ability to cure is strong, and TPGDA pairs
It is good in the adjustment effect of viscosity, and PEGDA has good hydrophily, by constantly testing adjustment, obtained TPGDA,
PO3- TMPTA and PEGDA has the gloss oil of this formula more excellent by weight the preferred hybrid plan of the ratio mixing of 2:3:1
Different performance；And different photoinitiators has the absorption of different wave length strong and weak ultraviolet light, due to the output of ultraviolet lamp
Energy is easy to be influenced by temperature, therefore photoinitiator 184,907,1173 mixes light by weight the ratio of 1:1:1 and draws
Hair agent has good absorbability for the ultraviolet lamp of a certain range wavelength；And suitable ethyl alcohol is added in water to be promoted
The dissolution of prepolymer and monomer etc., but ethyl alcohol addition is excessively difficult to control, the mixing of water and ethyl alcohol due to its volatility
