Abstract

The invention relates to a nanoscale highlight waterproof front-spraying light box piece. The light box piece consists of a transparent polyethylene terephthalate (PET) piece 1, a bottom pigment layer 2 on the front side of the transparent PET piece, and an ink absorption coating 3, a highlight color reduction layer 4 and an ultraviolet (UV) protective layer 5 which are distributed on the bottom pigment layer 2. A method for preparing the piece comprises the following steps of: 1, coating a bottom pigment on the front side of the 0.2mm transparent PET piece in a high-voltage corona processing mode; 2, coating the ink absorption layer, the highlight color reduction layer and the UV protective layer at a time in an extrusion coating mode after the bottom pigment is dried by a drying oven; and 3, slitting, rewinding and inspecting to obtain a finished product. The nanoscale highlight waterproof front-spraying light box piece has a high-gloss surface similar to a mirror surface and a simple process, is high in water resistance and weather resistance and low in cost, and is suitable for high-end commerce and trade display.

Description

Nanoscale high-gloss water-proof full-face spray light box sheet

Technical field

The present invention relates to lamp box panel, be specifically related to a kind of nanoscale high-gloss water-proof full-face spray light box sheet that high-end commerce and trade are showed that is used for.

Background technology

Along with becoming increasingly abundant and ad decoration fast development already of commodity, the use amount of inkjet advertising light box sheet in the ad decoration industry is increasing.Lamp box panel is a kind of special positive photosensitive material, and is similar with enlarging paper, and also the technology with enlarged photograph is identical on manufacture craft, is widely used in advertisement, propaganda, displaying of lamp box, placard, platform, show window etc. etc.Lamp box panel can be divided into two types, and one type is transparent, is the full impregnated sheet, and one type is translucent, cries half to pass through sheet, also is too white sheet.The full impregnated lamp box panel, only under the irradiation of light, it is bright in luster just can to seem, and when not having light-illuminating, a slice that will seem is dark.Half passes through lamp box panel does not have the effect that light-illuminating also can show photochrome, and through light-illuminating, it is more gorgeous to seem.Lamp box panel also can be divided into back of the body spray lamp box panel and full-face spray light box sheet.Back of the body spray lamp box panel is that light sees through image and shoots out, thereby shows image overleaf, and under the situation of no light-illuminating, the image that prints sees that from the back side image is pale.But waterproof full-face spray light box sheet is under the situation of no light-illuminating, and image effect is appointed so gorgeous, is more suitable for being used for high-end high trade and shows.

Summary of the invention

The purpose of this invention is to provide a kind of high-gloss surface and nanoscale high-gloss water-proof full-face spray light box sheet of favorable waterproof property that has as the minute surface; Its color density is high, color rendition is true to nature, colour gamut is wide, anti-stroke of wiping, water-fastly soak, anti-xanthochromia, use the paint ink printing that good sun-resistant performance is arranged; Can realize nondiscolouring in 100 years; Be more suitable for being used for high-end high trade and show, as to industries such as the exigent jewelry of lamp box panel.

The objective of the invention is to reach through following measure: step is following: 1. handle through high-voltage corona, coat silane coupling agent in the clear PET sheet front of 0.2mm; 2. after oven for drying, adopt the extrusion coated mode once to be coated with ink-absorbed coated layer, the color reducing zone of specular and UV protective layer; 3. through cut, rewinding and check finished product.

Press such scheme, nanoscale high-gloss water-proof full-face spray light box sheet is characterized in that silane coupling agent is an aqueous acrylic emulsion described in step 1..

Press such scheme, nanoscale high-gloss water-proof full-face spray light box sheet, it is characterized in that ink-absorbed coated layer described in step 2. by 32% polyvinyl alcohol, 10% Ludox, 12% absolute ethyl alcohol, 32% deionized water, 10% boric acid and 4% auxiliary agent by weight being made into.

Press such scheme, nanoscale high-gloss water-proof full-face spray light box sheet is characterized in that color reducing zone 40% polyvinyl alcohol of specular described in step 2., 15% Ludox, 40% deionized water and 5% auxiliary agent are by weight being made into.

Press such scheme, nanoscale high-gloss water-proof full-face spray light box sheet is characterized in that the 2. middle Ludox of step adopts nanometer grade silica.

Press such scheme, nanoscale high-gloss water-proof full-face spray light box sheet is characterized in that said auxiliary agent is color-fixing agent, fluorescent whitening agent, wetting agent, surfactant, PH conditioning agent, water absorbing agent, levelling agent.

Press such scheme, nanoscale high-gloss water-proof full-face spray light box sheet is characterized in that the UV protective layer is selected UV blocking agent paranitrobenzoic acid for use described in step 3..

Nanoscale high-gloss water-proof full-face spray light box sheet; Have following characteristics: 1. Ludox adopts nanometer grade silica; Can be evenly dispersed in the poly-vinyl alcohol solution; And the good interface combination being arranged with polyvinyl alcohol, dry back forms the surface of high glaze, shows favorable mechanical performance and water repelling property; 2. surface gloss is high, resolution ratio is high, when imaging, plays high light action, satisfies the color requirement, is more suitable for being used for high-end high trade and shows; 3. have stronger water-proof function, in water, soak 48h nondiscolouring, demoulding not, be more suitable for as the full-face spray light box sheet; 4. utilize nanometer silicon dioxide particle pore volume, bigger specific area and accumulation hole to absorb ink and fixation, can reach quick-drying purpose; 5. the UV protective layer makes it that good weatherability arranged, and can realize nondiscolouring in 100 years; 6. cost is low, and price is decided to be 30 yuan/m 2, with 480 yuan/m of external import price 2Compare, very big competitive advantage is arranged.
