Description

A kind of silver halide image exports film bottom antistatic coating fluid and its preparation method and application
Technical field
The invention belongs to printing supplies technical field, and in particular to a kind of silver halide image exports film bottom antistatic coating fluid and its preparation method and application.
Background technology
Before 2000, the World PCB output value 70% is distributed in Europe, America（Mainly North America）, three areas such as Japan.Since 21 century, PCB industrial focal points are constantly shifted to Asia, form new industrial pattern.The Asia PCB output values, close to the 90% of the whole world, are that the leading of World PCB, especially China and south east asia increase most fast.Counted according to Prismark, since 2006, China exceedes Japan turned into that the global output value is maximum, fastest-rising PCB manufacture bases, and has turned into the major growth power of promotion World PCB industry development.The China's Mainland PCB output values reach 216.36 hundred million dollars within 2012, account for the 39.84% of the World PCB gross output value.2008 to 2012, the annual average compound growth rate of the PCB in China output value reached 9.52%, higher than global growth level.Predict that the PCB in China output value is up to 289.72 hundred million dollars within 2017, accounts for the 44.13% of the global gross output value according to Prismark.
Nineteen ninety is constantly lifted with the performance of digital printing new product, and traditional printing film market is in continuous atrophy.Lithographic film market is exited in grand duke Skoda, Konica of the world with printing plate film in succession.But, still there is 40,000,000 square metres of annual consumption in domestic lithographic film market.And it will be a process for gradual change that film is withdrawn from the market completely.
Therefore either for silver salt PCB films or silver print film, there is boundless market, it is external also there was only several companies now being engaged in silver halide image and export the production of film, on solve the silver halide image output antistatic problem of film documents and materials they all hold in close confidence.
The base material of silver halide image output film is PET sheet base, and PET sheet base is very easy to produce electrostatic.In dry season, either take the packaging of film apart, or film carries out light on image output machine and paints, and is all very easy to produce electrostatic due to the friction between the friction between film and film, film and image output machine roller, cause the improper exposure of film, cause to waste.Film is when image output machine glazing is painted, burning for image output machine laser head may be caused due to the friction between film and roller, it is serious to govern silver halide image output film promoting the use of commercially, especially in air dried season, as the autumn and winter of northern China, and the state such as Pakistan.
Publication CN 103865364A describe a kind of antistatic coating fluid of polythiophene and its manufacture method, this coating fluid can only be coated on substrate surface and play antistatic property, if being coated one layer of silver halide image output light reaching the film layer on its antistatic coating, can not only influence silver halide image to export the photosensitive property of film, also result in silver halide image output light reaching the film layer and come off from this antistatic coating.Especially silver halide image output film needs to use soda acid in aobvious fixing, therefore this antistatic coating of publication introduction does not reach requirement completely.And this antistatic coating fluid that publication is introduced configures complexity, time-consuming, drying time is long, and drying temperature requirement is high, and required drying temperature has exceeded the limit that PET sheet base can bear, and industrialization degree is low.
The content of the invention
The present invention provides a kind of silver halide image output film bottom antistatic coating fluid and its preparation method and application, and the preparation method is simple to operation, and working condition requirement is extremely low；The coating fluid made using the method, good stability is not only good with PET sheet base fastness and also very good with the fastness of silver halide emulsion layer, with very strong resistance to acids and bases, good connection function and antistatic property can be played in silver halide image output film.
To achieve the above object, the technical solution adopted by the present invention is as follows：
The invention provides a kind of silver halide image output antistatic coating fluid of film bottom, it is made up of following materials in percentage by mass：Polythiophene dispersions 0.25%-1.9%, gelatin 0.4%-5%, ethanol 4%-19%, surfactant 0.1%-10%, crosslinking agent 0.4%-5%, balance of deionized water.
Contain synthetic resin 5%-15%, polythiophene 0.1%-1%, dimethyl sulfoxide (DMSO) 5-15%, balance of water in the polythiophene dispersions.
The surfactant be 2- sodium sulfonates-succinic acid di-isooctyl and 2- sodium sulfonates-succinic acid dihexyl in one or more.
The crosslinking agent is one or more in the double ethernamine base ethane of isocyanates, the chloro- 6- oxos -1.3,5- triazines sodium of 2,4- bis- and 1,2-.
The described silver halide image output film bottom preparation method of antistatic coating fluid, comprises the following steps that：Weigh in polythiophene dispersions, gelatin, ethanol, surfactant, crosslinking agent and the deionized water addition reactor of formula ratio, 5 ~ 30min is stirred under mixing speed is 100 ~ 700r/min.
The silver halide image for exporting the antistatic coating fluid of film bottom using above-mentioned silver halide image exports film, and the structure of silver halide image output film is from top to bottom followed successively by silver emulsion cuticular layer, silver halide emulsion layer, bottom, PET sheet base, bottom, antihalation layer and antihalation cuticular layer；The silver halide image output antistatic coating fluid of film bottom has been coated with the two sides of the PET sheet base.
A kind of preparation method that use silver halide image output film bottom exports film with the silver halide image of antistatic coating fluid, specific make step is as follows：Silver halide image is exported into the antistatic coating solution of film bottom on PET sheet base two sides, the normal practical formulations that silver halide image exports film are pressed after drying, antihalation layer and cuticular layer are coated with successively in one side, and silver halide emulsion layer and cuticular layer are coated with successively in another side coating after drying.
The drying is 110 ~ 135 DEG C of temperature, 90 ~ 300s of drying time.
Application of the film bottom with antistatic coating fluid on other base materials is exported using above-mentioned silver halide image, silver halide image output film bottom is specifically coated directly onto other substrate surfaces with antistatic coating fluid.
Compared with prior art, the advantage of the invention is that：
The silver halide image output antistatic coating fluid of film bottom that the present invention is prepared, it is coated on PET sheet base, dried 90 seconds under the conditions of 120 DEG C, obtain about 0.1 micron of antistatic bottom, more than half an hour, with EST121 types numeral ultra-high resistance, micro current instrument measures its sheet resistance to balance can reach 10 under conditions of air humidity is less than 25%6Ohm, is fully able to solve the antistatic problem that silver halide image exports film.
Silver halide emulsion layer and cuticular layer or antihalation layer and cuticular layer in coating on the antistatic bottom, its dry fastness is detected with cross-cut methods, it is found that the comes off not at all fastness that then do of coating is qualified.After being processed through alkaline-based developer and acid fixer, hand rubbing film is used, test its wet fastness, coating does not fall off, then wet fastness is qualified.By the film after aobvious being fixed, by after 60 DEG C and 120 DEG C of high temperatures experiment, its demoulding performance being detected with cross-cut methods, in the absence of coating shedding phenomenon, then demoulding performance is qualified.Silver halide image output film production requirement is produced by positive, detects that the photosensitive property of film is good.
