Abstract

The invention relates to a gravure bronze printing ink without defects and lost points, which is prepared by mixing the following components in percentage by weight: 20-40% of cellulose acrylate gold varnish, 10-20% of green gold powder, 10-25% of inorganic compound, 0.1-0.2% of metal complex dye used as a colorant and 30-40% of n-propyl ester used as a solvent, wherein the inorganic compound is prepared by mixing iron oxide yellow and calcium bicarbonate according to the ratio of 7 to 3 in parts by weight and adding a small amount of cellulose acrylate gold varnish for dispersing at high speed and sanding, and the fineness is less than 25 micrometers. The invention is characterized in that the gravure bronze printing ink can be used for replacing the existing gravure bronze printing cigarette brand ink, improves the quality of printing materials, can be widely applied to gravure printing, has uniform gold color, does not have defects and lost points, and has stable and durable prints; the gold cigarette brand has good glossiness and smoothness; gold powder can not fall out under the temperature of higher than 220 DEG C; and the consumption of the gold powder is lowered, thereby reducing the products cost.

Description

Do not have incomplete nothing and lose gravure bronze printing ink a little

Technical field the invention belongs to a kind of improvement of gravure bronze printing ink, promptly a kind of do not have incomplete do not have lose gravure bronze printing ink a little.

Background technology often will be carried out the gold printing at the various character patterns of color printing on the packing box of cigarette, on the filter tip, to increase the impression effect that packing box and cigarette prop up, promotes the commodity image of cigarette product.In order to strengthen antifalse effect, also usually use the intaglio plate mode and print, increase technical difficulty to the fake producer, make it be difficult to reach the purpose of mixing the spurious with the genuine.This has brought technical pressure also for simultaneously the legal producer, and with regard to existing gravure gold ink, it is by the blue or green bronze of the vinylformic acid gold-mixed oil of 35-50%, 20-25% and the solvent composition of 30-40%.It exists a lot of not enough; At first be that its prescription is unreasonable, three constituent elements only arranged, a little less than the mutual collocation and combined action; Often occur in the printing that gold is lost a little and incomplete; Literal after the colouring and pattern heatproof effect and wear resisting property are all poor, the higher and friction of Yin Wendu is often arranged on the cigarette machine production line and decolour, lack the look phenomenon and take place, and scrap rate is difficult to control.Not only cause the waste of gravure bronze, production cost is increased, What is more, as accidentally some indiscoverable waste products being come into the market, instead make certified products be considered to fake products.To oneself causing very passive situation.

Summary of the invention the object of the invention is exactly the problem that exists in the existing printing ink; A kind of new prescription scheme is proposed; Promptly do not have incomplete nothing and lose gravure bronze printing ink a little,, solve the deficiency of prior art to reduce significantly even to eliminate incompleteness and the phenomenon of losing gold on the gravure bronze printing.

The incomplete nothing of this nothing that the present invention proposes is lost gravure bronze printing ink a little, it is characterized in that it is mixed by following compositions in weight percentage:

The plain gold-mixed oil 20～40% of acrylic fibre;

Blue or green bronze 10～20%;

Mineral compound (yellow oxide of iron: Calcium hydrogen carbonate=7: 3 (weight ratio)): 10～25%;

Tinting material (metallized dye): 0.1～0.2%;

Solvent (n-propyl): 30～40%.

Mineral compound is with yellow oxide of iron and Calcium hydrogen carbonate, mixes according to 7: 3 ratios of weight part, adds the plain gold-mixed oil of a small amount of acrylic fibre, carries out high speed dispersion, sand milling, and fineness reaches below 25 microns.

Metallized dye is the product of buying on the market, and brand is the bright scholar in Taiwan, and model is y-20.

Solvent is a n-propyl, is monomer, uses general.

By the synthetic printing ink of above-mentioned prescription, be used for replacing the original printing ink of applicant unit, all the other conditions are constant.The technique effect of being obtained is following:

1, on the Red River cigarette-brand that is applied to our unit's production of success, make this product that further raising arranged qualitatively.

2, when developing Red River first class yew paper, golden degold occurs and cause yew paper undesired in the use of cigarette machine.After having used this printing ink, through the test of Honghe Cigarette Factory, the result of use on the cigarette machine is superior to other supply of material producer to the first class yew paper that our unit produces, and receives the favorable comment at red cloud Red River Honghe Cigarette Factory of group technical point center smoothly.Existing red cloud Red River group formally purchases the Red River first class yew paper that my company produces, about 200～400 tons of year amount of purchase.

3, reduce product cost.Add mineral compound, reduced the consumption of bronze, its price is lower than bronze price, has reduced product cost.

4, use the golden cigarette-brand of this ink printing and yew paper to have good glossiness peace solidity.Bronze can not come off yet under high temperature more than 220 ℃, guarantees the use properties of product on the cigarette machine.

5, this printing ink can be widely used in intaglio printing, and is evenly golden, do not have incompleteness, do not have and lose some the trace stability and durability.

Appended drawings is modulated the process flow sheet of printing ink for the present invention.

Embodiment is as shown in the figure, and at first mixing is moistening with commercially available blue or green bronze and solvent (commercially available n-propyl), and the time generally is no less than 2 hours.Add plain gold-mixed oil of acrylic fibre and mineral compound (yellow oxide of iron: Calcium hydrogen carbonate=7: 3) stir in proportion, add solvent adjustment viscosity at last according to circumstances, make it to meet confidential asking then in proportion.This routine viscosity is 16 seconds-18 seconds (2# examines the grace cup).Mineral compound is with yellow oxide of iron and Calcium hydrogen carbonate, mixes according to 7: 3 ratios of weight part, adds the plain gold-mixed oil of a small amount of acrylic fibre, carries out high speed dispersion, sand milling, and fineness is below 25 microns.

The plain gold-mixed oil of acrylic fibre is commercial goods (produce like Red River, Yunnan Muller Da Feng company, model is df-s8014, and the date manufactured is on December 8th, 2009).

Through repeatedly experiment and practical, the proportioning of above-mentioned each component is pressed low end value, intermediate value and high end value value separately respectively; A component is got intermediate value, and all the other components are got high end value and low end value respectively; A component is got high value, and when all the other components were got intermediate value and low end value respectively, the gravure effect of gained was all basic identical, and just color has difference slightly.But all do not have decolouring, incompleteness, lose golden phenomenon.All that supply with red cloud Red River group in applicant unit need in the cigarette cigarette-brand of bronze printing look Red River, degold never occurred during last machine packing, lose a little, and golden problem is lost in friction.Quality product and packing are fitted property and are all reached technical requirements.Receive the favorable comment at red cloud Red River Honghe Cigarette Factory of group technical point center.Existing red cloud Red River group formally purchases the Red River first class yew paper that my company produces, about 200～400 tons of year amount of purchase.Techno-economic effect very significantly.
