Problems solved by technology

Solvent-based ink needs to be baked at high temperature for a long time, which consumes a lot of energy, and the solvent volatilizes during the baking process, causing serious environmental pollution; if two-color or multi-color printing is required, multiple baking is required, the process is complicated, and the product cycle is long.
Although the decal process can be formed at one time, the cost is high and the yield rate is low, and it takes a long time to bake and consumes a lot of energy

Embodiment 1

[0046] A Add 5.925 kg of isobornyl acrylate, 3.75 kg of dimethylacrylamide, and the rotation speed is 300-500r / min. While stirring, add 4.5 kg of acylphosphine oxide, 0.75 kg of thioxanthone and its derivatives, and Titanium 75g, stir evenly, heat, fully dissolve, make initiator;

[0047] B. At the speed of 600-900r / min, add 30kg of polyester acrylate, 30kg of polyurethane acrylate, 5kg of ethoxylated bisphenol A diacrylate, 2kg of wetting and dispersing agent, and 7kg of pigment to the initiator obtained in step A. 10kg of filler (silicon dioxide powder) is stirred evenly, after being ground on a three-roller machine to below 5μm, then 0.8kg of defoamer and 0.2kg of leveling agent are added, and stirred evenly, the LED used on the surface of the glass bottle is obtained. Cures the ink.

Embodiment 2

[0049] A Add 5kg of isobornyl acrylate, 6.4kg of dimethylacrylamide, and the rotating speed is 300-500r / min. While stirring, add 7.6kg of acylphosphine oxide, 0.6kg of thioxanthone and its derivatives, and titanocene 0.2kg, stir evenly, heat, fully dissolve, and obtain the initiator;

[0050] B At the speed of 600-900r / min, add 35kg of polyester acrylate, 20kg of polyurethane acrylate, 8kg of ethoxylated bisphenol A diacrylate, 4kg of wetting and dispersing agent, and 5kg of pigment to the initiator obtained in step A 1. Filler (talc powder) 7kg, stir evenly, grind to below 5μm on a three-roller machine, then add 0.5kg of defoamer, 0.5kg of leveling agent, stir evenly, and it can be used for LED curing on the surface of glass bottles ink.

Embodiment 3

[0052] A Add 7.875kg of isobornyl acrylate, 7.875kg of dimethylacrylamide, the rotating speed is 300-500r / min, while stirring, add 13.5kg of acylphosphine oxide, 0.15kg of thioxanthone and its derivatives, 0.6kg of titanium, stirred evenly, heated in an oven at 90°C, fully dissolved, and prepared the initiator;

[0053] B At the speed of 600-900r / min, add 38kg of polyester acrylate, 8kg of polyurethane acrylate, 9kg of ethoxylated bisphenol A diacrylate, 5kg of wetting and dispersing agent, and 3kg of pigment to the initiator obtained in step A 1. Stir 5g of filler (talc powder) evenly, grind it to below 5μm on a three-roller machine, then add 1kg of defoamer and 1kg of leveling agent, stir evenly, and then get the LED curable ink for the surface of the glass bottle.

[0054] In the above-mentioned Examples 1-3, the maximum absorption wavelength of the acylphosphine oxide is at 380nm, and there is also absorption at 430nm in the visible light region; the effective absorption p...

Abstract

The invention discloses an LED curing ink used on the surface of a bottle body, a composite ink based on the LED curing ink, a preparation method and a curing method of the LED curing ink. An LED curable ink used on the surface of a bottle body. In terms of weight percentage, the LED curable ink is mainly composed of the following components: 30-40% polyester acrylate, 10-30% polyurethane acrylate, Ethoxylated bisphenol A diacrylate 5‑10%, initiator 15‑30%, dispersant 2‑5%, pigment 3‑8%, filler 5‑10%, defoamer 0.5‑1%, leveling agent 0.2‑1%. The LED curing ink used on the surface of the bottle body provided by the present invention can realize surface curing under the irradiation of the LED light source and exposure, and can carry out continuous two-color or multi-color overprinting, eliminating the need for repeated baking procedures and saving energy. consumption, manpower and time.

Description

technical field [0001] The invention belongs to the field of printing ink, and in particular relates to an LED curable ink used on the surface of a bottle body, a composite ink based on the LED curable ink, a preparation method and a curing method of the LED curable ink. Background technique [0002] At present, in the wine bottle and cosmetics printing industry, most of them use screen to print solvent-based ink or printing on the surface of the bottle (frosted bottle or bare bottle). Solvent-based ink needs to be baked at high temperature for a long time, which consumes a lot of energy, and the solvent volatilizes during the baking process, causing serious environmental pollution; if two-color or multi-color printing is required, multiple baking is required, the process is complicated, and the product cycle is long. . Although the decal process can be formed at one time, the cost is high and the yield rate is low, and it requires a long time to bake and consumes a lot of ...
