Abstract
The invention discloses a kind of methods that outer water cuts on-line heating co-extrusion decorating film, the scraping and wiping resistance performance for the face coat that outer water is cut can effectively be increased, reduce the risk of disbonding, externally it can cut base material offer protection effect by water simultaneously, the failure for avoiding outer water from cutting cuts to provide and is more widely applied range for outer water.
Description
Technical field
The present invention relates to a kind of methods that the outer water for auto parts manufacture field cuts on-line heating co-extrusion decorating film.
Background technology
For the failure for ensureing wearability and the aesthetics of outer water cut of automobile and preventing outer water from cutting, need on outer water cut of automobile
One layer of coating of setting protects it.Conventional method is to cut one layer of increase about thickness to outer water outside extrusion die at present
For the coating of 0.15mm, but since the flaw that the external water of the coating cuts substrate surface is very sensitive, the material product that any outer water is cut
The quality fluctuation that matter or outer water cut processing technology is all easy to cause the failure of coating, while conventional method also is difficult to realize coating
Edge joins are cut with outer water and form a smaller fillet, this is easy for that coating is caused to be easy to be detached from from substrate surface.And it is outer
If water cuts surface and is easy to be complained by client since coating failure leads to occur open defect.
Invention content
The purpose of the invention is to overcome the deficiencies of the prior art and provide a kind of outer water, to cut on-line heating co-extrusion decoration thin
The method of film, it can produce a kind of outer water that surface securely pastes coating and cut product.
Realizing a kind of technical solution of above-mentioned purpose is：A kind of method that outer water cuts on-line heating co-extrusion decorating film, packet
Include following steps：
Step 1, deployment step cut the speed of production line by coating coiled strip synchronous expansion according to outer water；
Step 2, preheating steps, the coating that coating coiled strip has been unfolded preheat；
Step 3, coating fixating shape step will bend to the shape for being bonded outer water and cutting by pre-warmed coating；
Step 4 pastes step, and the coating patch by bending is covered the substrate surface that Wai Shui is cut；
Step 5, press step, and outer water cuts the outer water of production line extrusion and cuts product, and extrusion die applies a direction to coating
The pressing force of base material；
Step 6, cooling step are cut product to the outer water of extrusion and are cooled down.
Further, the coating of the coating coiled strip is the plastic film layers with protective layer.
Further, the structure of the protective layer is followed successively by top cover layer, dyed layer, plating network layers and glues from outside to inside
The thickness of coating, the protective layer is 20-40 μm.
Further, the thickness of the plastic film layers is 500 μm.
A kind of outer water of the present invention cuts the technical solution of the method for on-line heating co-extrusion decorating film, passes through above-mentioned technique stream
Journey so that coating and base material are completely embedded, and base material can be completely covered in coating edge, and protective layer can improve the scratch resistance of coating
Performance is wiped, and thickness and hardness that coating itself provides can play protection base material, prevent the effect of substrate failure.Use this
The outer water that the technique of invention is processed, which cuts product, has wider array of application range.
Description of the drawings
Fig. 1 is that the method that a kind of outer water using the present invention cuts on-line heating co-extrusion decorating film carries out outer water to cut product crowded
The schematic diagram gone out；
Fig. 2 is that the structure that a kind of outer water of the present invention cuts coating used in the method for on-line heating co-extrusion decorating film is shown
It is intended to.
Specific implementation mode
In order to preferably understand technical scheme of the present invention, below by specifically embodiment and in conjunction with attached drawing
It is described in detail：
Referring to Fig. 1, the method that a kind of outer water of the present invention cuts on-line heating co-extrusion decorating film, includes the following steps：
Step 1, deployment step cut the speed of production line by 1 synchronous expansion of coating coiled strip according to outer water；
Step 2, preheating steps preheat the coating 2 that coating coiled strip 1 has been unfolded；
Step 3, coating fixating shape step will bend to the shape for being bonded outer water and cutting by pre-warmed coating 2；
Step 4 pastes step, and the coating 2 by bending is pasted to 3 surface of base material for covering Wai Shui and cutting；
Step 5, press step, and outer water cuts the outer water of production line extrusion and cuts product, and extrusion die applies a direction to coating
The pressing force of base material 3；
Step 6, cooling step are cut product to the outer water of extrusion and are cooled down.
Wherein, for step 3, coating fixating shape step, while being bent coating 2, using tool on the side of coating 2
Edge forms a smaller fillet so that the outer water that coextrusion can be completely covered in the edge of coating 2 cuts the edge of base material 3, prevents
The only stripping of coating 2 and base material 3.
Referring to Fig. 2, the coating of the coating coiled strip is the plastic film layers 21 with protective layer.The knot of the protective layer
Structure is followed successively by top cover layer 22, dyed layer 23, plating network layers 24 and covers layer 25 from outside to inside, and the thickness of the protective layer is a
=20-40 μm.The thickness of the plastic film layers is b=500 μm.The thickness of entire coating is about 530 μm.
The method that a kind of outer water of the present invention cuts on-line heating co-extrusion decorating film, it is total using product is cut with coating and outer water
Crowded method cuts the coating of one layer of about 0.53mm thickness of surface (EPDM or TPV) formation to improve the appearance matter of product in Wai Shui
Amount.This method is to be covered in the surface of product by on-line heating coating and coating and product extrudes realization jointly.
Those of ordinary skill in the art it should be appreciated that more than embodiment be intended merely to illustrate the present invention,
And be not used as limitation of the invention, as long as in the spirit of the present invention, the change to embodiment described above
Change, modification will all be fallen within the scope of claims of the present invention.
