The invention relates to a waterproof ink-jet printing plate-marking transparent film used in printing plate-making industry, which is characterized in that the film is provided with a single-layer coating layer; the coating emulsion comprises polyvinyl alcohol with the polymerization degree of 1000 to 5000 and alcoholysis degree of 88 percent, silicon dioxide dispersion solution with nanometer-class grains and alumina dispersion solution with nanometer-class grains. In order to improve the waterproofing performance of the film coating and keep excellent colour reduction performance, crosslinking agent sodium tetraborate is added into the coating emulsion of the invention and the pH value is adjusted and controlled within 6.5 to 7.0, thus greatly improving the preservation property of thecoating ink-adsorption imaging. The mass ratio of the nanometer-class silicon dioxide to polyvinyl alcohol in the coating emulsion is 3 to 5:1; the mass ratio of the nanometer-class alumina to the polyvinyl alcohol is 1.5 to 2:1. By adopting the formulation, the advantage of good colour when the alumina component is added can be kept and the advantage of good brightness when the silicon dioxide component is added can be kept, thus improving the glossiness of the coating by more than 75 percent and leading the opacity not to be more than 9 percent.
Description
Technical field
The present invention relates to the plate making technology, particularly a kind of waterproof ink jet printing plate-making transparent film and preparation thereof that is used for the plate making industry.
Background technology
At present, the conventional laser phototypesetting film has characteristics such as resolving power height, density are big, but its loaded down with trivial details dark room operation makes the whole cost of plate making high, and the waste liquid that process caused has contaminative.Along with improving constantly of inkjet technology, the particularly application of piezo technology, the output accuracy and the fabric width of ink jet printing device are improved constantly, this just makes the inkjet technology application expand to digital image output field and print field gradually from the advertisement output field in past, it is easy to use especially, fast, characteristics such as environmental protection promptly are printed the plate-making industry and admit.Compare with the conventional laser phototypesetting film, there is a big difference again on performance indications such as water proofing property, black density, transparency for the homemade inkjet printing graphic arts film that has occurred.
Therefore, a kind of waterproof ink jet printing plate-making transparent film and preparation thereof that is used for the plate making industry is provided, improving the quality and the performance of film coating emulsion, effectively solve the problem that prior art exists, is one of this technical field scientific research personnel new problem of being badly in need of developing.
Summary of the invention
The waterproof ink jet printing plate-making transparent film and the preparation thereof that provide a kind of dependable performance, obvious results to be used for the plate making industry are provided for overcoming the weak point of prior art.
The technical solution adopted in the present invention is for achieving the above object: a kind of waterproof ink jet printing plate-making transparent film that is used for the plate making industry is characterized in that described film is provided with signal layer coating; The emulsion of this coating comprises that the major ingredient degree of polymerization is 1000～5000, alcoholysis degree is 88% polyvinyl alcohol, and mass concentration is 20% nano-scale particle silica dispersions, and mass concentration is that the alumina fluid dispersion of 40% nano-scale particle mixes; Described coating emulsion adds the crosslinking agent sodium tetraborate and regulates the pH value, make the pH value be controlled at 6.5～7.0, the mass ratio of nanometer grade silica and polyvinyl alcohol is 3～5: 1 in the described coating emulsion, and the mass ratio of alumina in Nano level and polyvinyl alcohol is 1.5～2: 1, and adds auxiliary agent routinely.
Described auxiliary agent comprises polyether surfactant, and addition is 0.1% of a major ingredient gross mass.
Described auxiliary agent comprises plasticizer polyethylene glycol-200, and addition is 0.2% of a major ingredient gross mass.
Described auxiliary agent comprises the cation color-fixing agent, and addition is 0.03% of a major ingredient gross mass.
A kind of preparation that is used for the waterproof ink jet printing plate-making transparent film of plate making industry, when it is characterized in that preparing emulsion, at first poly-vinyl alcohol solution is heated to 55～75 ℃, add silica dispersions successively in the poly-vinyl alcohol solution after heating then, alumina fluid dispersion and crosslinking agent sodium tetraborate solution, high-speed stirred is 3～10 minutes after a kind of component of every adding, rotating speed 〉=2000rpm; Add auxiliary agent then routinely, after treating all to add, stirred 5～10 minutes again, temperature is reduced to 40～60 ℃, and insulation is standby down.。
The invention has the beneficial effects as follows: be a novel flexible CTP plate-making technology that is used for inkjet printing plate-making.The present invention is coated with in the emulsion process for preparation, because the adding crosslinking agent is crosslinked with the hydroxyl above the polyvinyl alcohol, increases the film forming and the compactness extent of coating, effectively improves the waterproof ability of coating.Draw the good advantage of single alumina component color on the one hand after taking the present invention to fill a prescription, kept the advantage of silica component good brightness on the other hand.Take the coating after this combination that the glossiness of coating is brought up to more than 75%, opacity≤9%, its water proofing property, quick-drying and firmness performance are very good.Using product of the present invention can finish drawing a design, export color separation film one machine before layout, composing, the seal; Have need not to set type, the advantage of colour-separation drafting, reduced image transfer number of times and transfer indfficiency; Problems such as, poor visualization few than conventional silver halide laser photo film mask-making technology; Draw materials conveniently, cost is low, the slice expense is far below the slice expense of conventional laser film setter and projection multiplying arrangement; Speed is fast, and the site is clear, dependable performance, effect highly significant.The present invention fills a prescription rationally, and high-efficiency environment friendly fills the domestic gaps, and can be widely used in advertising and plate making industry, and technology is simple, easy to operate.
