Abstract

The utility model discloses a reflecting paper, including intermediate level and reflection stratum, the biaxial stretching's who did not foam for at least one deck in the intermediate level PET film, the reflection stratum is the biaxial stretching's of foaming type PP film, and paste in the both sides in intermediate level with compound glue respectively in the reflection stratum, and transparent material is chooseed for use to the PET film, and the thickness of PET film is 0.1mm~0.3mm, and the intermediate level forms for individual layer PET film or multilayer PET film complex, and the thickness of PP film is 0.065mm~0.17mm. The utility model provides a PET reflecting paper's in the existing market production technology harsh, the production line input cost is very high, product thickness has the restriction simultaneously, the deflection is not enough when making the large size product, easy modification, and resistant book the, the easy problem of creasing that produces.

Description

A kind of reflecting paper

Technical field

This utility model relates to reflectance coating class Material Field, a kind of three-in-one new type reflection paper.

Background technology

Reflecting paper herein is to be applied in backlight module and flat board illuminating product, rises and improves product brightness A kind of film material, market is also named reflectance coating, it appears that like paper, is collectively referred to as reflecting paper herein.

Main flow reflecting paper in the market is mainly that to add multiple filler be formula to former material with PET, passes through The PET film biaxial tension equipment of import is manufactured out, is generally PET reflection paper (film), has Following several shortcoming:

(1) production line input cost is the highest, and formula for raw stock cost and manufacturing cost are high, and these public affairs The compound reflecting paper equipment investment cost of department's utility model and the cost of raw material and manufacturing cost are the most very Low；

(2) product thickness restricted (the most all within 0.35mm thickness), thus cause product deflection to have Limiting, when manufacturing large-sized product, deflection is inadequate, easy modification, and this product thickness can accomplish 1mm Even thicker, deflection is the best；

(3) not folding, easily produces crease (because this reflectance coating uses foam process to produce) Therefore substantial amounts of defective products can be produced during using, and the folding of this product, it is not easy to produce and crease, significantly Reduce defective products rate.

Utility model content

Problem to be solved in the utility model is that the production technology of PET reflection paper in the market is harsh, raw Producing line input cost the highest, product thickness is restricted simultaneously, and when manufacturing large-sized product, deflection is inadequate, Easily modification, and not folding, easily produces the problem creased, it is provided that a kind of production cost is low, product deflection Good, a kind of reflecting paper being applicable to large scale reflection product of folding.

In order to solve above-mentioned technical problem, this utility model provides a kind of reflecting paper, including intermediate layer and reflection Layer, intermediate layer is the PET film of the unexpanded biaxial tension of at least one of which, and reflecting layer is the two-way of expansion type The PP thin film of stretching, reflecting layer is affixed on the both sides in intermediate layer respectively with composite glue.

Further, PET film selects transparent material.

Further, the thickness of PET film is 0.1mm～0.3mm.

Further, intermediate layer is the composite bed that two-layer PET film is composited.

Further, the thickness of PP thin film is 0.065mm～0.17mm.

Compared with prior art, the beneficial effects of the utility model are:

(1) equipment investment low cost, manufacturing cost is low；

(2) do not limited by thickness, the product of a lot of different-thickness can be produced, substantially increase product The deflection suitability；

(3) due to PET reflection paper be use expansion type technique, product density is relatively low, therefore not folding, Easily producing folding line after folding, and the PET in this product intermediate layer uses unexpanded, density is the highest, table PP reflecting layer, face is relatively thin, therefore folding, and is not likely to produce folding line, during decreasing greatly product use Scrappage.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical scheme in this utility model embodiment, embodiment will be described below The accompanying drawing used required in is briefly described, it should be apparent that, the accompanying drawing in describing below is only this Some embodiments of utility model, for those of ordinary skill in the art, are not paying creative work On the premise of property, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of detailed description of the invention.

Detailed description of the invention

Below in conjunction with the accompanying drawings and embodiment, detailed description of the invention of the present utility model is further described.With Lower embodiment is only used for clearly illustrating the technical solution of the utility model, and can not limit this with this The protection domain of utility model.

As it is shown in figure 1, a kind of reflecting paper, including intermediate layer 1 and reflecting layer 2, intermediate layer 1 is not sent out for two-layer The clear PET film of the biaxial tension of bubble, unexpanded PET film density is the highest, has enough deflections, Bend-resistance simultaneously, the thickness of PET film is 0.2mm, has suitable deflection and warping resistance；Reflecting layer 2 For the PP thin film of the biaxial tension of expansion type, the thickness of PP thin film is 0.1mm, is ensureing reflecting paper reflection While rate, the film adhered intermediate layer of relatively thin PP is not easy to produce folding line, and compound adhesive is used in reflecting layer 2 respectively Water is affixed on the both sides in intermediate layer, makes reflecting paper two-sided use or face of changing to use, saves material and cost.

This utility model by make use of the heat-resisting quantity of common biaxial tension PET, high density high-stiffness, become This is low, and the advantage of the high reflectance of expansion type PP thin film, and two kinds of different materials can be crossed the production of laminating Technique, is manufactured that a kind of performance is more excellent, the new type reflection paper that cost is lower.Production this utility model is anti- The equipment penetrating paper is simple, and input cost is low, and manufacturing cost is low；Do not limited by thickness, can be according to need Produce a lot of large-sized product；Reflecting paper the most of the present utility model solves PP reflecting paper heatproof Inadequate to ordering defect.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
