According to a second aspect of the embodiments of the present invention, the system that one kind two-way injection molding heat of two axis turns laminated film is provided
Standby technique, includes the following steps:
Two kinds of functional membranes are sent foil machine to be sent into molding die by step 100 by two respectively；
Step 200, in injection molding, from side injection moulded clear sizing material between two layers of functional membrane, formed and be in two layers of function
Transparent workpiece between energy film；
After step 300, cooling molding, two layers of functional membrane is then attached in the transparent workpiece, forms the wear-resisting knot of anti-scratch
Structure layer and the complete workpiece with depth, color and lines.
Further, which is applied to cell phone back cover and handheld wrist meter apparatus.
Further, it is respectively that X-axis send foil machine and Y-axis to send foil machine that foil machine is sent described in two.
Further, the transparent gross rubber is optical grade PE and PC.
Further, functional membrane described in two kinds is respectively the pattern layer and lines layer for being used as bottom, and as surface layer
Hardened layer.
The embodiment of the present invention has the advantages that
The multilayered structure of functional membrane is divided into two by the present invention, is prepared into two kinds of functional membranes, then by under same system
Two are sent foil machine to be sent into molding die, can directly be formed from side toward material feeding between two kinds of functional membranes, can be formed table
Layer has anti-scratch wearproof structural tier (hardened layer), and has depth, and the complete workpiece that color and lines are integrated can be avoided punching
The situation of mould occurs, and ejection formation yield is not necessarily to spraying up to 95%, without environmental protection and pollution problem.
The present invention can be integrally formed and may be readily formed as curve surface work pieces, and process rate is high, and the system of transparent workpiece can be greatly reduced
This is caused, existing adhering film to glass technology can be substantially replaced.
Detailed description of the invention
It, below will be to embodiment party in order to illustrate more clearly of embodiments of the present invention or technical solution in the prior art
Formula or attached drawing needed to be used in the description of the prior art are briefly described.It should be evident that the accompanying drawings in the following description is only
It is merely exemplary, it for those of ordinary skill in the art, without creative efforts, can also basis
The attached drawing of offer, which is extended, obtains other implementation attached drawings.
Structure depicted in this specification, ratio, size etc., only to cooperate the revealed content of specification, for
Those skilled in the art understands and reads, and is not intended to limit the invention enforceable qualifications, therefore does not have technical
Essential meaning, the modification of any structure, the change of proportionate relationship or the adjustment of size are not influencing the function of the invention that can be generated
Under effect and the purpose that can reach, should all still it fall in the range of disclosed technology contents can cover.
Fig. 1 is the preparation technology flow chart that the embodiment of the present invention 2 provides；
Specific embodiment
Embodiments of the present invention are illustrated by particular specific embodiment below, those skilled in the art can be by this explanation
Content disclosed by book is understood other advantages and efficacy of the present invention easily, it is clear that described embodiment is the present invention one
Section Example, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall within the protection scope of the present invention.
Embodiment 1:
It provides one kind two-way injection molding heat of two axis and turns laminated film, the bottom surface including being separately positioned on workpiece two sides
Layer and hardened layer, the bottom surface layer include pattern layer and lines layer, and the lines layer is arranged in the pattern layer.
The hardened layer is soft HC material and with 300 DEG C of heatproof > of polymer matrix composites；In the hardened layer
On can also be equipped with texture transfer film, the depth of texture lines improves microscopic carvings surface hardness up to 16~18um or more, realizes wear-resisting
With the characteristic of scratch resistance, reach finer presentation quality and 3D visual effect.
The multilayered structure of functional membrane is divided into two, two kinds of functional membranes are prepared into, is separately positioned on workpiece (transparent)
Two sides, so that being formed has anti-scratch wearproof structural tier and have the complete workpiece that is integrated of depth, color and lines.
Embodiment 2:
As shown in Figure 1, providing one kind two-way injection molding heat of two axis turns the preparation process of laminated film, including walk as follows
It is rapid:
Two kinds of functional membranes are sent foil machine to be sent into molding die by step 100 by two respectively, and foil machine is sent to distinguish described in two
Foil machine and Y-axis is sent to send foil machine for X-axis；
Step 200, in injection molding, from side injection moulded clear sizing material (optical grade PE and PC) between two layers of functional membrane,
Form the transparent workpiece between two layers of functional membrane；
After step 300, cooling molding, two layers of functional membrane is then attached in the transparent workpiece, forms the wear-resisting knot of anti-scratch
Structure layer and the complete workpiece with depth, color and lines.
In the present embodiment, heat, which turns laminated film, can be widely applied to computer and smart phone, such as specifically can be
Cell phone back cover and handheld wrist meter apparatus.
Functional membrane described in two kinds is respectively the pattern layer and lines layer for being used as bottom, and the hardened layer as surface layer.
Currently, the problem of adhering film to glass backboard, is general are as follows: bend glass processing is not easy, and adhering film to glass processing yield is low, only
Having percent 50 or so, and before pad pasting, substrate is still needed to print or be sprayed, and it is at high cost, there is the problem of air pollution.
The technique for comparing adhering film to glass backboard, heat turns the preparation process of laminated film in the present embodiment, by the more of functional membrane
Layer structure is divided into two, and is prepared into two kinds of functional membranes, then send foil machine to be sent into molding die by two under same system, can
Directly to form from side toward material feeding between two kinds of functional membranes, surface layer can be formed with (the hardening of anti-scratch wearproof structural tier
Layer), and there is depth, the complete workpiece that color and lines are integrated, the situation that can be avoided punch die occurs, and without spray
It applies, without environmental protection and pollution problem, and is integrally formed and may be readily formed as curve surface work pieces, process rate is high, can be substantially up to 95%
The manufacturing cost for reducing transparent workpiece, can substantially replace existing adhering film to glass technology.
Although above having used general explanation and specific embodiment, the present invention is described in detail, at this
On the basis of invention, it can be made some modifications or improvements, this will be apparent to those skilled in the art.Therefore,
These modifications or improvements without departing from theon the basis of the spirit of the present invention are fallen within the scope of the claimed invention.
