Abstract
The utility model discloses a reflecting film which comprises a base layer (1). One or both sides of the base layer (1) are provided with reflecting surfaces formed by rolling with a roller. The base layer is formed by extruding one or more microcellular foam. Pores (2) are reserved in the base layer (1). The reflecting surfaces are composed of pyramid-shaped projections (3) evenly and tightly arranged. The reflecting film has the advantages of fine performance, high reflective brightness, light weight and high stiffness, the problem of reducing weight of large-sized display screens is solved, and cost of manufacturing and using the reflecting film is also lowered.
Description
Technical field
The utility model relates to a kind of reflectance coating.
Background technology
at present, at liquid crystal indicator, illumination instrument, reflectance coating and reflector plate have been used in a large number in lighting advertisement etc., wherein, transmitting film is mostly a smooth plane, although can carry out reflection of light, but, the reflectance coating of this single smooth flat in use can cause because of the loss of specular light brightness to reduce, simultaneously, due to the reflectance coating of single smooth flat in use, heat-resisting effect is relatively poor, easily deformation occuring and causes reflectance coating to upwarp, cause the generation of shadow phenomenon, in order to solve the problem of mirror-reflection light loss, many producers reduce mirror-reflection by viscose in the means that reflectance coating applies transparent convexity layer, but, do like this and exist efflorescence to peel off unabiding shortcoming, simultaneously, make reflectance coating by such means, also make the manufacturing cost of reflectance coating higher.In order to address the above problem, in existing reflectance coating, also have by conventional three roll-ins and prolong the white reflection film of production, and increased projection and improved reflecting brightness on the reflecting surface of reflectance coating, but the reflectance coating of this structure, due to the inorganic reflective particle that contains high concentration, cause reflectance coating than great, be unfavorable for the lightweight of large scale display screen.
The utility model content
The purpose of this utility model just is to provide the reflectance coating that a kind of quality is light, hardness is strong.
The purpose of this utility model is to realize by such technical scheme, a kind of reflectance coating, comprise basic unit, the one side of basic unit or two-sided on be provided with the reflecting surface that forms with the running roller roll extrusion, described basic unit is made of one or more layers of little Foamex extruding, be provided with hole in described basic unit, the pyramid shape projection that described reflecting surface is served as reasons evenly and close-packed arrays arranges consists of.
Wherein, the described adjacent two peak-to-peak distances of pyramid shape projection ripple are between 0.015mm～0.1mm, and the height of described each pyramid shape projection is between 0.05mm～0.1mm.
Further, the voidage in described basic unit is at 30-60%, and described hole is spherical, and hole diameter is at 1um-5um.
Owing to having adopted technique scheme, the utlity model has the advantage that usability is good, reflecting brightness is high, lightweight, stiffness is high, adopt it not only to solve the light-weighted problem of large scale display screen, but also reduced manufacturing cost and the use cost of reflectance coating.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail; but the utility model is not limited to these embodiments; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of reflectance coating, comprise basic unit 1, the one side of basic unit 1 or two-sided on be provided with the reflecting surface that forms with the running roller roll extrusion, described basic unit is made of one or more layers of little Foamex extruding, be provided with hole 2 in described basic unit 1, the pyramid shape projection 3 that described reflecting surface is served as reasons evenly and close-packed arrays arranges consists of.
The described adjacent two pyramid shape projection 3 peak-to-peak distances of ripple are between 0.015mm～0.1mm, and the height of described each pyramid shape projection 3 is between 0.05mm～0.1mm.
In the utility model, when light was injected on reflecting surface, because reflecting surface is to be made of pyramid shape projection 3, pyramid shape projection 3 had disperse function, its reflectivity is higher, so just reduce the interference between light and light, made the brightness of the rear light of reflectance coating reflection higher, simultaneously, through experiment, under such distance and height dimension scope, pyramid shape projection 3 can reach better reflective condition
In order to arrive the purpose of lightweight, and have higher reflectivity simultaneously, the voidage in described basic unit 1 is at 30-60%, and described hole 2 is spherical, and hole 2 diameters are at 1um-5um.Do like this and can make the requirement of large scale display screen so that lighter weight of the present utility model has satisfied under the lightweight condition, simultaneously, also satisfied the requirement of stiffness.
In the utility model, described little Foamex can be not limited to make by techniques such as chemical blowing, microcapsules foaming and the little foaming of overcritical inert gas.
