Abstract
The invention relates to a nanoscale high-gloss cast coated paper for printing. The preparation method of the nanoscale high-gloss cast coated paper for printing comprises the steps of: 1) selecting cast coated base paper: printing the coated base paper through an offset plate; 2) applying coating on the base paper by using a steel wire scraper, attaching the base paper onto a glossing plate, squeezing out excessive coating and placing the glossing plate on a glossing machine for drying; and 3) after the dried high-gloss cast coated paper automatically falls off, cutting, rewinding and inspecting the dried high-gloss cast coated paper to obtain finished products. The coating consists of pure water, nanoscale silicon powder, polyvinyl alcohol solution with concentration being 10%, ethylene vinyl acetate (EVA) emulsion, color fixing agents, stripping agents, brightening agents and silicone oil defoaming agents according to certain weight ratio. The nanoscale high-gloss cast coated paper for printing provided by the invention can be obtained through one-step drying and formation without conducting super-calendering, and has the characteristics of high gloss, no pinhole, easiness in stripping, high drying speed, good printing effect and the like, the preparation process is simple, the operation is convenient to conduct and the economic benefit is higher.
Description
Technical field
The present invention relates to a kind of casting type of being coated with paper, be specifically related to a kind ofly be coated with printing that method makes with nanoscale Gao Guangzhu type of being coated with paper by direct casting.
Background technology
Cast-coated paper is the smooth especially senior coated printing paper in a kind of surface.The body paper that will scribble coating (comprising pigment, adhesive and other various additives) ride over heating, have on the chromium plating dryer surface of bright luster through high polish, through the dry converted paper that strips down, be called cast-coated paper.Cast-coated paper has high glossiness and smoothness; Good ink absorption is arranged; And print performance is good; Its finished product is bright in colour, color rendition is true to nature, and decorative effect is superior to art paper, therefore is widely used in printing high-grade fine arts picture, bookcase front cover, inset, colour advertisement and senior carton etc.
The casting and coating technique method has multiple, like direct method, wet method and gel method etc. again.Tradition direct method technology is because casting is coated with the preceding no drying process of processing, and the coating drying is slower, causes dry load bigger, and drying time is longer.Again wet method because " rewetting " technology only makes coating surface partly plastify whole coating substantially dry, so rate of drying is very fast, helps improving the speed of a motor vehicle, increases output, pin hole is arranged, connect airtight unequal problem but be easy to generate the casting coating surface.In addition, cast-coated paper can be clean peels off from the drying cylinder voluntarily is the key of producing the high-quality cast-coated paper, is fit to and an amount of remover or the chrome-plated surface of drying cylinder is carried out chemical purification handle and can reach the desirable effect of peeling off voluntarily through selecting for use.The present invention selects rational nano-level coating prescription for use, through the first drying moulding, obtains high glaze, is prone to peel off and cast-coated paper that rate of drying is fast, shortens the dry coating problem of also having avoided the rewetting method to produce the time consuming time of direct method.
Summary of the invention
The purpose of this invention is to provide a kind of printing with nanoscale Gao Guangzhu type of being coated with paper; Through the first drying moulding; Need not supercalendering can obtain; Have high glaze, free of pinholes, be prone to peel off, characteristic such as rate of drying is fast and printing effect is good, its preparation technology is simple, easy to operate, economic benefit is higher.
Content of the present invention is to print with nanoscale Gao Guangzhu type of being coated with paper, obtains through following several steps: 1. select casting to be coated with body paper: 60g/m
2The hectographic printing bodystock paper; 2. body paper is coated with the steel wire scraper and is attached on the glazing plate after coating, squeeze out unnecessary coating and glazing plate is placed on the polisher dry again; 3. dried Gao Guangzhu type of being coated with paper comes off automatically, through cut, rewinding and check finished product.
With nanoscale Gao Guangzhu type of being coated with paper, it is characterized in that the coating described in step 2. is made into by certain weight ratio by 60%-65% pure water, 10%-15% nanoscale silica flour, 9%-10% poly-vinyl alcohol solution (10%), 9%-10%VEA emulsion, 5%-7% color-fixing agent, 0.2%-0.3% remover, 0.1%-0.15% brightening agent and 0.02%-0.03% silicon oil foam killer by the printing of such scheme.
With nanoscale Gao Guangzhu type of being coated with paper, it is characterized in that the preparation method for coating described in step 2. is by the printing of such scheme: in material-compound tank, add a certain amount of pure water, color-fixing agent, remover, silicon oil foam killer and brightening agent successively, 700r/min stirs and adds 10% polyvinyl alcohol behind the 5min; After stirring 5min once more, slowly add a certain amount of silica flour, continue to stir 90min; Add the VEA emulsion at last and add a certain amount of pure water; Stir 45min, after stopping to stir, filtration gets final product.
With nanoscale Gao Guangzhu type of being coated with paper, it is characterized in that the silica flour main component in the said coating is that particle diameter is the silica of 5-20nm by the printing of such scheme.
With nanoscale Gao Guangzhu type of being coated with paper, it is characterized in that the remover in the said coating is a tributyl phosphate by the printing of such scheme.
With nanoscale Gao Guangzhu type of being coated with paper, it is characterized in that the color-fixing agent in the said coating is resin cation type color-fixing agent H-35 by the printing of such scheme.
With nanoscale Gao Guangzhu type of being coated with paper, it is characterized in that the bake out temperature described in step 2. is 90-100 ℃ by the printing of such scheme.
With nanoscale Gao Guangzhu type of being coated with paper, it is characterized in that the drying time described in step 2. is 3-4min by the printing of such scheme.
High light cast-coated paper has following characteristics: 1. add nano material in the coating, utilize its particle pore volume, bigger specific area and accumulation hole to absorb ink and fixation, can reach quick-drying purpose, help enhancing productivity; 2. through the first drying moulding, need not supercalendering can obtain, and technology is simple and easy to operate; 3. cast-coated paper is prone to peel off, and does not have sticking cylinder phenomenon; 4. the paper glossiness that strips down is high, under 5 times of magnifying glasses, observes free of pinholes; 5. print performance is good, and its finished product is bright in colour, color rendition is true to nature, can be used to print high-grade fine arts picture or colour advertisement etc.
