Abstract
The invention discloses a back-spraying lamp plate, comprising PET basic material and coating layer set on the surface. Bonding layer, graphite absorbing layer and light diffused layer are coated on the basic material in turn. The bonding layer comprises propylene double self-adhesive resin, non-drying glue of water agent propylene resin and deionized water. The graphite absorbing layer comprises polyvinyl alcohol, polyvinylpyrrolidone, cationic fixing agent, defoaming agent, whitening agent, deionized water and surfactant. The light diffused layer comprises deionized water, titanium dioxide, polyacrylic acid, silicon dioxide, isopropanol, 4.5-6.0 polyvinyl alcohols and interfacial agent. The invention adopts technical project mentioned above and can make picture of lamp box cleaner, more brilliant and more lifelike. It can decrease the cost. The product can be mainly applied in back lighting advertisement signboard used in quick transportation station, department store and airport and subway so on.
Description
Technical field
The present invention relates to a kind of lamp chip technology, particularly relate to a kind of back of the body spray light diffusion lamp sheet that is used for lamp box.
Background technology
To be used level in the main flow ink-jet technology the highest by the numerical digit colour is printd for back of the body spray light diffusion lamp sheet, production unit cost is the highest, manufactures the most difficult product, and it is configured to be coated with on transparent polyester (PET) film, comprise light diffusion layer, several layers of coating of ink absorbing layer and tack coat.It is applied as the rapid transit station, department store, the back side polishing advertising signboard that airport, places such as subway are used always.But the domestic research and development manufacturing that only has only a few manufacturer to be devoted to this product, and be limited to grasp deficiency to lamp sheet ABC and experience and coating dry technology, can't produce at present high-quality, the product of high yield.There are shortcomings such as rate of drying is slow, color reducibility is poor, light transmittance is not strong usually in existing product.
Summary of the invention
The technology used in the present invention can solve the defect problem that existing back spray lamp rate of drying is slow, color reducibility is poor, light transmittance is not strong.
Technical problem to be solved by this invention is achieved by the following technical solution: it comprises the PET base material and is coated on its lip-deep coating, be coated with tack coat, ink absorbing layer and light diffusion layer above the base material successively, tack coat is made into from glue connection resin, 5-18 part aqua allyl resin adhesive sticker and 200 parts of deionized waters by weight by 8-15 part propylene is two; Ink absorbing layer is adjoined pyrrolidone, 10-20 part cationic fixing agent, 15-25 part defoamer, 10-28 part brightening agent, 50-200 part deionized water and 5-15 part surfactant by 45-65 part polyvinyl alcohol, 17-23 part polyethylene and is made into by weight; Light diffusion layer is made into by weight by 75-90 part deionized water, 3.5-5.5 part titanium dioxide, 0.65-0.90 part polyacrylic acid, 18-30 part silica, 9-12 part isopropyl alcohol, 4.5-6.0 part polyvinyl alcohol and 0.04 part of interfacial agent.
The technique scheme that the present invention adopts owing to can solve the defect problem that rate of drying is slow, color reducibility is poor, light transmittance is not strong, can make the lamp box picture more clear, more bright-coloured, and image is more true to nature; Owing to shortened drying time, also be beneficial to machine-shaping, thereby reduced cost.
The specific embodiment
This kind back spray lamp comprises the PET base material and is coated on its lip-deep coating, be coated with tack coat, ink absorbing layer and light diffusion layer above the PET base material successively, tack coat is made into from glue connection resin, 5-18 part aqua allyl resin adhesive sticker and 200 parts of deionized waters by weight by 8-15 part propylene is two; Tack coat is in order to increase the adherence between coating and the PET base material.Ink absorbing layer is adjoined pyrrolidone, 10-20 part cationic fixing agent, 15-25 part defoamer, 10-28 part brightening agent, 50-200 part deionized water and 5-15 part surfactant by 45-65 part polyvinyl alcohol, 17-23 part polyethylene and is made into by weight; Ink absorbing layer is adjoined the pyrrolidone material by adding polyvinyl alcohol and polyethylene, improves the color reducibility of lamp sheet.Light diffusion layer is made into by weight by 75-90 part deionized water, 3.5-5.5 part titanium dioxide, 0.65-0.90 part polyacrylic acid, 18-30 part silica, 9-12 part isopropyl alcohol, 4.5-6.0 part polyvinyl alcohol and 0.04 part of interfacial agent.The about 4.7-6.5 of light diffusion layer PH that is mixed with is subacidity.Light diffusion layer has improved the light transmittance of lamp sheet by the triplicity of titanium dioxide, silica and interfacial agent.By the adding of polyacrylic acid and isopropyl alcohol, shortened the drying time of coating.Ink sees through large-scale draught machine ejection, by light diffusion layer, arrives ink absorbing layer, and rests in the ink absorbing layer.Export the figure shelves of desiring to print to lamp sheet Hou, (light diffusion layer face) polishing evenly disperses light overleaf, then can see evenly bright coloured image by positive (PET substrate surface).
The preparation technology of tack coat of the present invention is: two propylene earlier from glue connection resin and the mixing of aqua allyl resin adhesive sticker, and then the adding deionized water fully stirs promptly.
The preparation technology of ink absorbing layer of the present invention is: polyvinyl alcohol, polyethylene are adjoined pyrrolidone and deionized water places the closed reactor continuous stirring; under protection of nitrogen gas, refluxed through 4 hours; add cationic fixing agent and surfactant subsequently; continue to add thermal agitation 2 hours; add defoamer and brightening agent at last; stirring and obtaining solid content in 40 minutes is 17-25%, and viscosity is the liquid of 2500-3200 centipoise.
The preparation technology of light diffusion layer of the present invention is: deionized water, titanium dioxide, silica and polyvinyl alcohol are placed the closed reactor continuous stirring; under nitrogen protection, refluxed through 6 hours; add polyacrylic acid, isopropyl alcohol and interfacial agent subsequently again; 80 ℃ of down reactions 4 hours obtain solids content and are 34.8%, viscosity is the thick liquid of 5300 centipoises (25 ℃).
