Abstract
The invention discloses reflective paper. The reflective paper comprises a middle layer and reflective layers, wherein the middle layer comprises at least one layer of unfoamed bidirectionally-stretched PET (polyethylene terephthalate) thin film; the reflective layers are foamed bidirectionally-stretched PP (polypropylene) thin films; the reflective layers are glued to the two sides of the middle layer by compound glue respectively; the PET thin film is made of a transparent material; the thickness of the PET thin film is 0.1-0.3mm; the middle layer is a single-layer PET thin film or is compounded by multiple layers of PET thin films; the thickness of the PP thin film is 0.065-0.17mm. The reflective paper solves the problems that the PET reflective paper in the current market is strict in production process, very high in production line investment cost, limited in product thickness, as well as insufficient in stiffness, easy to deform, low in folding resistance and easy to generate folds when a large-sized product is manufactured.
Description
Technical field
The present invention relates to reflection film material field, it is a kind of three-in-one new type reflection paper specifically.
Background technology
Reflecting paper herein is applied in backlight module and dull and stereotyped illuminating product, works a kind of film material improving product brightness, market is also named reflectance coating, seems like paper, be collectively referred to as reflecting paper herein.
Main flow reflecting paper in existing market is mainly that to add multiple filler be formula to former material with PET, manufactures out by the PET film two-way stretch device fabrication of import, is usually PET reflection paper (film), has following several shortcomings:
(1) production line input cost is very high, formula for raw stock cost and manufacturing cost height, and our company invention compound reflecting paper equipment investment cost and material cost and manufacturing cost all very low;
(2) product thickness restricted (generally all within 0.35mm thickness), thus cause product deflection restricted, when manufacturing large-sized product, deflection is inadequate, it is easy to modification, and this product thickness can accomplish that 1mm is even thicker, deflection is very good;
(3) not folding, it is easy to produce to crease (because this kind of reflectance coating adopts foam process to produce) therefore can produce a large amount of defective productss in use procedure, and the folding of this product, it is not easy to produce to crease, greatly reduce defective products rate.
Summary of the invention
The production technique that the problem to be solved in the present invention is the PET reflection paper in existing market is harsh, production line input cost is very high, product thickness is restricted simultaneously, when manufacturing large-sized product, deflection is inadequate, it is easy to modification, and not folding, easily produce the problem creased, thering is provided a kind of production cost low, product deflection is good, a kind of reflecting paper being applicable to large size reflection product of folding.
In order to solve the problems of the technologies described above, the present invention provides a kind of reflecting paper, comprises middle layer and reflecting layer, and middle layer is the PET film of the two-way stretch that at least one layer does not foam, reflecting layer is the PP film of the two-way stretch of expansion type, and reflecting layer is affixed on the both sides in middle layer respectively with composite glue.
Further, PET film selects transparent material.
Further, the thickness of PET film is 0.1mm��0.3mm.
Further, middle layer is the composite bed that two layers of PET film is composited.
Further, the thickness of PP film is 0.065mm��0.17mm.
Compared with prior art, the useful effect of the present invention is:
(1) equipment investment cost is low, and manufacturing cost is low;
(2) do not limit by thickness, it is possible to produce the product of a lot of different thickness, substantially increase the deflection suitability of product;
(3) owing to PET reflection paper is the technique adopting expansion type, product density is lower, therefore not folding, easily produce folding line after folding, and the PET in this product middle layer adopt do not foam, density is very high, PP reflecting layer, surface is relatively thin, therefore folding, and not easily produce folding line, decrease greatly the condemnation factor in product use procedure.
Accompanying drawing explanation
In order to the technical scheme being illustrated more clearly in the embodiment of the present invention, below the accompanying drawing used required in embodiment being described is briefly described, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structural representation of embodiment.
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is further described. Following examples are only for clearly illustrating the technical scheme of the present invention, and can not limit the scope of the invention with this.
As shown in Figure 1, a kind of reflecting paper, comprises middle layer 1 and reflecting layer 2, middle layer 1 is the clear PET film of the two-way stretch that two layers are not foamed, and the PET film density not foamed is very high, has enough deflections, resistance to bending simultaneously, the thickness of PET film is 0.2mm, has suitable deflection and warping resistance; Reflecting layer 2 is the PP film of the two-way stretch of expansion type, the thickness of PP film is 0.1mm, while ensureing reflecting paper reflectivity, the film adhered middle layer of thinner PP also not easily produces folding line, reflecting layer 2 is affixed on the both sides in middle layer respectively with composite glue, reflecting paper two-sided use or face of changing can be used, save material and cost.
The present invention is by make use of the high thermal resistance of common two-way stretch PET, high-density high-stiffness, and cost is low, with the advantage of the high-reflectivity of expansion type PP film, two kinds of different materials can be crossed the production technique of laminating, produced a kind of performance more excellent, the new type reflection paper that cost is lower. The equipment of production reflecting paper of the present invention is simple, and input cost is low, and manufacturing cost is low; Do not limit by thickness, it is possible to produce a lot of large-sized product as required; In addition the reflecting paper of the present invention solve PP reflecting paper heatproof inadequate to ordering defect.
The foregoing is only the better embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment of doing, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
