Abstract
The invention relates to a film laminating process for a notebook computer metal shell. The film laminating process comprises the following steps in sequence: slitting, cleaning, transferring, baking, removing a PET (polyethylene glycol terephthalate) film, laminating a protective film, inspecting, performing punching molding, removing the protective film and curing. According to the film laminating process, an adhesion assistant is jetted on the surface of an aluminum plate along with a flame after oil removal is completed, so that patterns and the like transferred on the aluminum plate are adhered relatively firmly; the phenomenon that a transfer layer is worn can be basically eliminated after baking and UV (ultraviolet) curing.
Description
Technical field
The present invention relates to a kind of notebook metal shell coating technique.
Background technology
The method of directly printing is mostly adopted at present at the outer impressing pattern of metal shell, but the pattern be directly printed on metal is very easily worn, some also adopts transfer modes overlay film, but the patterns on transfer film etc. not easily bond with metal, the complete post processing of transfer printing is improper, makes transfer printing layer still not wear-resisting.
Summary of the invention
The object of this invention is to provide a kind of notebook metal shell coating technique.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of notebook metal shell coating technique, and it comprises the following steps successively: cut, clean, transfer printing, toast, go PET film, pasting protective film, inspection, punch forming, go diaphragm, solidification; Described point is cut to Aluminum Cutting is become multi-disc aluminium sheet; Described cleaning comprises washing, dedusting, oil removing, and described dedusting adopts electrostatic precipitation, and described oil removing is after carrying out 6 ~ 10 flame calcinations to aluminium sheet, is sprayed onto on to be transferred of aluminium sheet by the adhesion promoter of liquid state with the flame sprayed; Institute's transfer printing is transferred on aluminium sheet by the ink layer on transfer film, and during transfer printing, aluminium sheet is positioned on the counterdie of transfer apparatus, and the temperature of counterdie is 80 ~ 90 DEG C, and the patrix temperature be pressed in by transfer film on aluminium sheet is 140 ~ 160 DEG C; Described baking is sent in baking oven by aluminium sheet good for transfer printing to toast, and baking temperature is 130 ~ 140 DEG C, and baking time is 15 ~ 25min.
Optimize, described diaphragm is PP or PE film.
Optimize, during oil removing, the speed of ejection adhesion promoter is 0.7 ~ 0.9L/min.
Further, need to lower the temperature to aluminium sheet after oil removing, be cooled to 30 ~ 40 DEG C.
Further, fan blowing is adopted to lower the temperature to aluminium sheet during cooling.
Optimize, after posting diaphragm, according to different housing requirements, punching is carried out to aluminium sheet.
Optimize, sent in ultraviolet photo-curing stove by notebook metal shell during solidification and be cured, hardening time is 6 ~ 10s, and ultraviolet energy is 800 ~ 900 MJs.
Beneficial effect of the present invention is: adhesion promoter is injected in surface of aluminum plate with flame by the present invention after oil removing completes, the pattern be transferred on aluminium sheet is made to equal aluminium sheet bonding more firm, again after overbaking, UV solidification, substantially can eliminate the phenomenon that transfer printing layer is worn.
Accompanying drawing explanation
Accompanying drawing 1 is flow chart of the present invention;
Detailed description of the invention
Below in conjunction with embodiment shown in the drawings, the present invention is described in detail below:
As shown in Figure 1, this notebook metal shell coating technique comprises the following steps successively: cut, clean, transfer printing, toast, go PET film, pasting protective film, inspection, punch forming, go diaphragm, solidification.
Divide to be cut to and aluminium is cut into multi-disc aluminium sheet by required size; Clean and comprise washing, dedusting, oil removing, natural air drying after washing, etc. dedusting again after air-dry, dedusting adopts electrostatic precipitation, oil removing is after carrying out 6 ~ 10 flame calcinations to aluminium sheet, be sprayed onto aluminium sheet to be transferred on the speed of 0.7 ~ 0.9L/min with the flame sprayed by the adhesion promoter of liquid state, general first flame sprays adhesion promoter 10 times again, and the speed of adhesion promoter gets 0.8L/min; Transfer printing is transferred on aluminium sheet by the ink layer on transfer film, during transfer printing, aluminium sheet is positioned on the counterdie of transfer apparatus, the temperature of counterdie is 80 ~ 90 DEG C, the patrix temperature be pressed in by transfer film on aluminium sheet is 140 ~ 160 DEG C, and counterdie temperature gets 80 DEG C, and patrix is compression roller, its heating-up temperature is 150 DEG C, and its rolling wire speed is 100m/min; Baking is toasted for being sent in baking oven by aluminium sheet good for transfer printing, and baking temperature is 130 ~ 140 DEG C, and baking time is 15 ~ 25min, and temperature the best gets 130 DEG C, time optimal gets 20min; Fan is utilized to make its temperature be down to 30 ~ 40 DEG C to aluminium sheet blowing after having toasted; Need after tearing the PET film of transfer film off on transfer surface, to stick PP or PE film as diaphragm; After posting diaphragm, according to different housing requirements, punching is carried out to aluminium sheet; Sent in ultraviolet photo-curing stove by notebook metal shell during solidification and be cured, hardening time is 6 ~ 10s, and ultraviolet energy is 800 ~ 900 MJs.Owing to adhesion promoter being injected in surface of aluminum plate with flame after oil removing completes, the pattern be transferred on aluminium sheet is made to equal aluminium sheet bonding more firm, selecting after oil removing, spray adhesion promoter is again because the aluminium sheet of high temperature can make the effect of adhesion promoter play more abundant, and then after overbaking, UV solidification, substantially can eliminate the phenomenon that transfer printing layer is worn.
Above-described embodiment, only for technical conceive of the present invention and feature are described, its object is to person skilled in the art can be understood content of the present invention and implement according to this, can not limit the scope of the invention with this.All equivalences done according to the present invention's spirit change or modify, and all should be encompassed within protection scope of the present invention.
