Abstract
A production method of a drum continuous-type reflective sheet comprises the steps as follows: 1, an ultra-transparent PET (polyethylene terephthalate) or PVC (polyvinyl chloride) drum sheet is selected to serve as a substrate; 2, an EVA (ethylene-vinyl acetate copolymer) raw material is added into an extrusion type casting machine and is fed into a narrow slit extrusion die head through a screw charging barrel, and cast on the substrate surface through the extrusion action of the narrow slit extrusion die head; 3, the substrate cast with the EVA rolls opposite to a silica gel clamping roller through a cooling steel roller provided with a reflective thin prism texture or other textures; and 4, trimming and finished product rolling up are performed. Compared with the production method of the conventional single sheet type hot-press reflective sheet, the production efficiency is improved by 60% through the production method, and simultaneously, the production cost is reduced by 70%. Besides, remarkable intense reflective function is achieved, the reflective sheet can further be bonded with other substrates through hot rolling for use, the application range is wide, the production cost is low, and the reflective sheet is suitable for various large-scale reflective occasions.
Description
Technical field
The invention belongs to the reflecting sheet material manufacture technology field, what be specifically related to is a kind of manufacture method of reel continous way reflecting sheet material.
Background technology
Reflecting sheet material is a kind of necessary material of reflective occasion that need to be applied to, and its range of application is more and more wider, for example outdoor advertising of non-electrical light-illuminating, and the highway communication reflecting sign, industries such as clothes need reflective position.
Present domestic manufacturing reflecting piece method is with the about 50mm of single sheet type * 50mm breadth hot-press method, because of its breadth limited, if when needing the reflective area of large format, also to finish through the splicing operation, and single sheet type hot pressing production efficiency is low, and per minute is produced 0.25 square metre, the production cost height; And also have a kind of reel to adorn the continous way reflecting sheet material abroad, but its surfacing is consolidated the reflective texture of light type moulding or refractive power texture with UV light, the cost of UV glue exceeds 4 times than EVA material cost, and the reflecting sheet material of UV gum forming can't be further bonding with other media; To fit and to be suitable for ground when for example reflecting sheet material is done outdoor advertising, and can't reach bonding requirement for existing UV gum forming reflecting piece, therefore a kind of reel of anxious solution is adorned the continous way reflecting sheet material, and this reflecting sheet material can be with the novel reflecting sheet material of the bonding use of other medium, and this case is given birth to therefrom.
Summary of the invention
The objective of the invention is at the deficiencies in the prior art, a kind of manufacture method of reel continous way reflecting sheet material is provided, the reflecting piece of utilizing this method to be made has with other medium easily bonding, and this reflecting piece is the reel continous way, the unlimited reel setting continuously of reflecting piece length.
The present invention is achieved by the following technical solutions: a kind of manufacture method of reel continous way reflecting sheet material, make according to the following steps:
The first step, the selection material is selected super transparent PET or PVC, and the reel packaging sheet of thickness 0.1mm is as ground;
Second step was ready to the extruded type casting machine, on this casting machine screw cylinder was set, and in the place ahead of screw cylinder the narrow slit extrusion die was set; The EVA raw material is joined in the extruded type casting machine, and the EVA raw material is through extruded type casting machine heating and melting, by the screw cylinder feeding to the narrow slit extrusion die; Through the squeezing action of narrow slit extrusion die, gradually EVA is drenched film to the ground face, pouring film amount 〉=25g/ ㎡ of EVA;
The 3rd step, EVA drenches cooling steel rider and the silica gel pinch roll subtend roll extrusion of ground by having reflective thin Ling mirror texture or other texture behind the film, this moment, EVA leaching membrane layer bottom surface and ground were bonding, and the cooling curing moulding of temporarily fitting of leaching membrane layer another side and the cooling steel rider that has reflective thin Ling mirror texture or other texture obtains reel continous way reflecting sheet material after release;
In the 4th step, trimming device is cut edge, and finished rolling device carries out the finished product rolling, and reel continous way reflecting piece is made.
Cooling steel rider in above-mentioned the 3rd step is that surface cladded with nickel sheet heart arranges the circulation ice-water device.
Beneficial effect of the present invention embodies and is: compared with prior art, the present invention and the manufacture method contrast of single sheet type hot pressing reflecting sheet material at present, the inventive method production efficiency improves 60%, and production cost reduces by 70% simultaneously; Reflecting sheet material of the present invention is except having significant strong reflection function, reflecting sheet material or refractive power sheet material production efficiency height that the present invention produces are used in all right light and bonding use of the hot roll extrusion of other grounds, and per minute is produced 4 square metres, production cost is low, is applicable to each large-scale reflective occasion.
Description of drawings
The present invention will be described in detail below in conjunction with accompanying drawing.
Fig. 1 is production procedure schematic diagram of the present invention.
Following is the concrete title of each sign among the figure: 1 extruded type casting machine, 2 reel packaging sheets, 3 silica gel pinch rolls, 4 reflective thin Ling mirror textures, 5 trimming devices, 6 finished rolling devices, 11 screw cylinders, 12 narrow slit extrusion dies.
The specific embodiment
A kind of manufacture method of reel continous way reflecting sheet material, make according to the following steps:
The first step, the selection material selects the reel packaging sheet of super transparent PET, thickness 0.1mm as ground, in order to strengthen its viscosity, must carry out corona pre-treatment to the pet sheet face;
Second step was ready to the extruded type casting machine, and this casting machine is used for hot melt EVA raw material, and the casting machine upper end arranges screw cylinder, and in the place ahead of screw cylinder the narrow slit extrusion die is set, and was used for that the material of the EVA behind the hot melt is carried out narrow slit and evenly extruded; After the EVA raw material joins and carries out the high temperature hot melt in the extruded type casting machine, by the screw cylinder feeding to the narrow slit extrusion die; Through the even squeezing action of narrow slit extrusion die, gradually EVA is evenly drenched film to the ground face, and pouring film amount 〉=25g/ ㎡ of EVA;
The 3rd step, EVA drenches cooling steel rider and the silica gel pinch roll subtend roll extrusion effect of ground by having reflective close grain behind the film, this moment, EVA leaching membrane layer bottom surface and ground were bonding fully, leaching membrane layer another side and the cooling steel rider that has a reflective close grain temporarily fit the cooling curing moulding release after, obtain reel continous way reflecting sheet material;
In the 4th step, trimming device is cut edge, and finished rolling device carries out the finished product rolling, and reel continous way reflecting piece is made.
