The material of film 21 is polyethylene terephthalate (PET), polybutylene terephthalate (PBT) (PBT), makrolon
(PC) one kind or in acrylic, using plastic film as intermediate supporting body, function admirable is cheap and be easy into
Type.The reflecting layer 22 is plated on the surface of the film 21, the reflecting layer on plane assembly line using technique for vacuum coating
22 material is one kind in aluminium silicon cladding, gold plate or silvering, and facet coatings avoid the problem in curved surface plated film, technique
Simply, equipment requirement is low, reduces cost.
Specifically, the present invention provides the film plating process of Photospot solar module curved mirror, include the following steps:
Step 1 pre-processes the film for not plating reflecting layer, and pretreatment includes drying process, dust collecting process and removes
Greasy dirt technique, this is the key that ensure vacuum coating coating quality, and film moisture content is high or surface has impurity that will influence coating
Adhesive force and follow-up end properties.
The material of film is plastics, and further the material of film is polyethylene terephthalate (PET), gathers to benzene
One kind in dioctyl phthalate butanediol ester (PBT), makrolon (PC) or acrylic, the wherein thickness range of film are 0.05-
0.5mm.The thickness range in reflecting layer is 70-110 μm.
Step 2, the coating adhesive face coating adhesive in film coat adhesive and cross baking oven later by the gluing of film surface
Agent baking and curing.Adhesive force of the reflecting layer on film is increased using adhesive, so that film and reflecting layer is combined more secured, applies
Adhesive is the key that ensure follow-up coating quality.
Step 3 uses technique for vacuum coating on plane assembly line, and a surface of film is plated reflecting layer, is made thin
Film sheet, plane pipelining is easily operated, and facet coatings avoid the problem in curved surface plated film, and simple for process, equipment is wanted
It asks low, curved mirror plated film is made to become easier to, can realize volume production, while reducing coating cost.
The material in reflecting layer is metal, and further, the material in reflecting layer is in aluminium silicon cladding, gold plate or silvering
It is a kind of.
Step 4, by the good protective film of the reflecting layer face paste of thin-film sheet, protective film is polyethylene terephthalate
(PET), one kind in polybutylene terephthalate (PBT) (PBT), makrolon (PC) or acrylic, the above this kind of material conduct
The wear-resisting scratch resistance of protective film, can preferably protect reflecting layer, prevent from destroying reflecting layer in subsequent step, reduce product surface matter
Amount is prepared for next step in-mould injection.
Curved substrate is arranged in step 5, the one side that protective film is not arranged in thin-film sheet, is molded curved mirror.In advance by coating
It is plated on plane assembly line on soft film, then makes curved mirror, coating process is simple, at low cost, and convenient for batch
Production.
Further, for step 5, there are two types of different methods to realize for we, and one of method is using note in mould
Modeling technique, the non-plated level straight forming that molten plastic is directly molded into thin-film sheet go out condenser, specifically include following step
Suddenly:
Step 61, the non-plated level adhesive coating in thin-film sheet, and baking and curing, then it is fabricated to cycle roller web-like
Band, the adhesive faec for the roll film sheet material made is smooth in the preceding die face of injection mold outwardly, just as labelling one
Sample faces outwardly the coating adhesive for the roll film sheet material made smooth in the preceding die face of injection mold, and this mode can be with
Realize that fully automatically tape loop movable type produces, and can be improved the degree of automation, adhesive coating can increase casting resin with it is thin
Binding force on film makes film be combined with casting resin more secured, is not easy to be layered.
Step 62 molds injection mold rear mold and preceding mould, and in clamping process, rear mold will be pressed into thin-film sheet
In preceding mould die cavity, it is identical as the curved mirror shape to be produced that mold is formed by mold cavity shapes after being closed.
Step 63, casting resin are injected to by injection port in die cavity by high-temperature fusion, the adhesive with thin-film sheet
Face is combined, and curved substrate is molded in adhesive layer side, is gone out curved mirror by being molded straight forming, is reduced precision and want
It asks, tolerance tolerance increases, and is conducive to system accuracy accuracy, reduces equipment cost, be easy to mass production.
Rear mold is deviate from after step 64, cooling, takes out the curved mirror of forming.
Repeat the above steps the batch production of achievable curved mirror, and equipment cost is relatively low, and cycle continuous production saves former material
Material, and production efficiency is high.
