Abstract
The utility model discloses a high brightness coating membrane, characterized in that at least three layers are provided. Form the bottom layer to the surface layer, a resin fiber layer, a titanium dioxide filler layer and a transparent resin layer are respectively provided. The transparent resin layer is arranged with fluorescent whitener. Because the fluorescent whitener and the titanium dioxide are positioned in different layers and the transparent resin layer provided with the fluorescent whitener is positioned above the titanium dioxide filler layer, the absorption of the titanium dioxide to the ultraviolet light can not influence the sufficient agitation of the fluorescent whitener. The yellow eliminating function can be effectively realized by the fluorescent whitener without using the blue pigment. Therefore, the titanium dioxide can fully display the function of improving the brightness, and the coating membrane has the effects of both high brightness and high whiteness.
Description
Technical field
The utility model relates to the structure of coated film, particularly the coated film of using as a white background in occasions such as advertisement, house fitting-up, productions of film and TV.
Background technology
In occasions such as advertisement, house fitting-up, productions of film and TV, often need to utilize a white background to set off prospect.White good background should have Gao Bai, high brightness under conventional light source, so just can make prospect obtain good diplopia effect under background.People's a kind of coated film commonly used is as a white background at present.This coated film is to apply one deck polyvinyl chloride on one deck fibrage.In order to make coated film have the effect of high brightness, adding in polyvinyl chloride layer has titanium dioxide, to improve coated film to the reflection of light effect, reaches the effect of high brightness.But the titanium dioxide colour temperature is below 4500K, form and aspect are yellow partially, therefore in polyvinyl chloride layer, also need add fluorescent whitening agent, its objective is that the inclined to one side yellow light mix that blue light and titanium dioxide reflected of utilizing fluorescent whitening agent to send forms the white light of colour temperature at 5000K～6500K, to improve the whiteness of coated film.But unfortunately be that fluorescent whitening agent needs ultraviolet light to excite, and titanium dioxide has very strong absorption to ultraviolet light just, so the effect that fluorescent whitening agent plays is very limited, can not reach the yellow purpose that disappears.For this reason, prior art also needs to add blue pigment in polyvinyl chloride layer, with the raising yellow effect that disappears, but can reduce brightness so again.This shows that prior art can't make the effect of coated film with high brightness and high whiteness all the time.
Summary of the invention
The purpose of this utility model provides a kind of coated film with high brightness and high whiteness effect.
The utility model is achieved in that coated film has three-decker at least, is respectively resin fibre layer, titanium dioxide packing layer and transparent resin layer by bottom to surface layer, has sneaked into fluorescent whitening agent in transparent resin layer.Because fluorescent whitening agent is positioned at different layerings with titanium dioxide, and the transparent resin layer at fluorescent whitening agent place is positioned at the top of titanium dioxide packing layer, therefore titanium dioxide can not influence fully exciting of fluorescent whitening agent to the absorption of ultraviolet light, make fluorescent whitening agent to play effectively to disappear yellow effect, need not to utilize again the blue pigment Huang that disappears, can make titanium dioxide give full play to the effect that improves brightness thus again, make the effect of coated film with high brightness and high whiteness.
The utility model has the advantages that can effectively utilize the inclined to one side yellow light mix that blue light and titanium dioxide reflected that fluorescent whitening agent sends forms the white light of colour temperature at 5000K～6500K, make coated film have the favorite 5000～6500K colour temperature of human eye, can strengthen human eye to the sensation of " in vain " with this coated film as white background, make prospect good diplopia effect of acquisition under a white background.
Description of drawings
Fig. 1 is the cross-sectional structure schematic diagram of coated film embodiment.
The specific embodiment
Referring to Fig. 1, the coated film of present embodiment has four-layer structure, is respectively resin fibre layer 1, titanium dioxide packing layer 2, trick paint layer 3 and transparent resin layer 4 by bottom to surface layer, has sneaked into fluorescent whitening agent 5 in transparent resin layer 4.Fluorescent whitening agent 5 can adopt fluorescent whitening agent OB or OB-1.Resin fibre layer 1 is the mixture of resin and fiber, plays the effect of other each layers of protection.The effect of trick paint layer 3 is to make coated film have pattern.If coated film does not need pattern, then trick paint layer 3 can be saved.Trick paint layer 3 used pigment can adopt common printing-ink, also can adopt various tools to penetrate the pigment of photosensitiveness, as pearlite, metal powder, radium-shine powder or the like, make pattern have sparkling effect.Titanium dioxide packing layer 2 can mix with titanium dioxide with glue, and fillers 6 such as adding calcium carbonate, talcum powder mix, and wherein glue plays adhesive effect, and fillers such as calcium carbonate, talcum powder play filling effect, to reduce cost.Because calcium carbonate, talcous reverberation usually can be slightly yellow, therefore correspondingly preferably sneak into fluorescent whitening agent 7 in titanium dioxide packing layer 2 again.Though titanium dioxide can influence the effect of fluorescent whitening agent,, therefore in the titanium dioxide packing layer, add fluorescent whitening agent and still can play the disappear effect of Huang of filler because calcium carbonate, talcous reverberation are just yellow slightly partially.
As preferred forms, the upper surface of the titanium dioxide packing layer 2 of present embodiment is rough surface, so can increase the reflective area of this layer, and can strengthen the adhesion strength with last layer.In like manner, the lower surface of titanium dioxide packing layer 2 also is rough surface, strengthens the adhesion strength of titanium dioxide packing layer and following one deck with this.For the durability that improves coated film and protect light, colour retention, the resin that the resin fibre layer of the bottom 1 is used, and the transparent resin layer 4 of the superiors preferably adopts the acrylic acid resinoid.The preparation method of coated film can adopt the mode of stack successively, at first the upper surface at resin fibre layer 1 applies the pasty state titanium dioxide packing layer 2 that one deck mixes with glue, fluorescent whitening agent 7 and filler 6, after treating that titanium dioxide packing layer 2 is done admittedly, surface-coated pigment thereon again, constitute needed pattern, on dried solid trick paint layer 3, apply the transparent resin of sneaking into fluorescent whitening agent 5 more at last, treat just to form transparent resin layer 4 after transparent resin is done admittedly, so far finish the making of coated film.In above-mentioned manufacturing process, can be bonded to one naturally between each layer.
