Problems solved by technology

Water-based ink is more and more valued and favored by people because it has almost no volatile organic compound VOCs emissions; 2. At present, due to the faster speed of the gravure printing machine, higher requirements are put forward for the adaptability of the ink. On the other hand, At present, water-based inks are slower to volatilize than ordinary alcohol inks, which further aggravates the poor film-forming properties of gravure printing machines when water-based inks are used, which can easily lead to printed matter paste and pattern loss; 3. But there is no water-based ink on the market. Achieve the effect of direct bronzing, poor temperature resistance

Embodiment 1

[0015] The 2000g composition contains 300g of water-based vinyl resin 701, 500g of water-based polyurethane resin FW-33-37, 130g of water-based polypropylene wax 2101, 80g of WinSperse4000, 110g of monoethanolamine, 260g of PR57:1, 65g of ethanol, and the rest is water. Use an emulsifier to stir at a high speed (2500-3000 rpm for 30-40 minutes), then use a grinder to grind at a speed of 0.2-0.3L per minute. After grinding three times, do relevant performance tests, directly take 500g of color and add 200g Dilute the 1:1 mixed solution of ethanol and water as ink, and then dilute 30-40% with ethanol and water 1:1 as the ink on the machine, apply the ink to the surface of the aluminum spray paper, put it in an 80-degree oven for 2 seconds to dry After that, let it dry before testing.

Embodiment 2

[0017] The 2000g composition contains 370g of water-based vinyl resin 701, 450g of water-based polyurethane resin FW-33-37, 110g of water-based polypropylene wax 2101, 100g of WinSperse4000, 100g of monoethanolamine, 280g of PR57:1, 80g of ethanol, and the rest is water. Use an emulsifier to stir at high speed (2500-3000 rpm for 30-40 minutes), then use a grinder to grind at a speed of 0.2-0.3L per minute. After grinding three times, do relevant performance tests, directly take 500g of color and add 150g Dilute the 1:1 mixed solution of ethanol and water as ink, and then dilute 30-40% with ethanol and water 1:1 as the ink on the machine, apply the ink to the surface of the aluminum spray paper, put it in an 80-degree oven for 2 seconds to dry After that, let it dry before testing.

Embodiment 3

[0019] The composition of 2000 parts by weight includes 260g of water-based vinyl resin 701, 400g of water-based polyurethane resin FW-33-37400g, 150g of water-based polypropylene wax 2101, 100g of WinSperse4000, 90g of glycol amine, 300g of PR57:1, 100g of ethanol, and the rest are water. Use an emulsifier to stir at high speed (2500-3000 rpm for 30-40 minutes), then use a grinder to grind at a speed of 0.2-0.3L per minute. After grinding three times, do relevant performance tests, directly take 500g of color and add 150g Dilute the 1:1 mixed solution of ethanol and water as ink, and then dilute 30-40% with ethanol and water 1:1 as the ink on the machine, apply the ink to the surface of the aluminum spray paper, put it in an 80-degree oven for 2 seconds to dry After that, let it dry before testing.

Abstract

The invention provides a water-based temperature-resistant stampable ink composition for aluminum sprayed paper to solve problems. Evert 100 parts by weight of water-based temperature-resistant stampable ink compositions for the aluminum sprayed paper comprise 10-20 parts of vinyl chloride-vinyl acetate resin, 20-30 parts of water-based polyurethane resin, 5-8 parts of water-based polypropylene wax, 3-5 parts of water-based dispersing agents, 3-8 parts of PH (potential of hydrogen) stabilizers, 10-16 parts of water-based pigments, 3-5 parts of ethyl alcohol and the rest water. The water-basedink is applicable to printing of the aluminum sprayed paper on a gravure press with printing speed capable of reaching 120-150m / min, and has the advantages of good stability and the like. Performanceindexes such as temperature resistance and gold stamping performance of printing materials can be obviously improved, and the printing materials have popularization and application values.

Description

technical field [0001] The invention belongs to the field of ink, and in particular relates to a high-speed gravure printing machine whose printing speed can reach 120-150 m / min, which is faster than common offset printing machines (80-100 m / min). Background technique [0002] Aluminum-sprayed paper is a kind of high-grade packaging and printing paper made by deep processing of ordinary white paper. Many of its advantages have long been known to people in the industry. However, because the surface of aluminum paper is metal aluminum, it is relatively smooth, and it is not easy to absorb ink. Its printability is very different from that of paper. The adhesion fastness of aluminum film. Therefore, high-quality ink must be used for gravure printing on aluminum-sprayed paper. At the same time, when the commercially available water-based ink is printed, it is very easy to cause the ink layer to have poor film-forming effect, low adhesion and easy to fall off. In view of the ab...
