Problems solved by technology

However, the disadvantage of this kind of ink is that it is expensive, the production is not easy to control, and the yield rate is not high, resulting in waste of cost
Moreover, after the ink is printed, it must be cured in an oven, which increases the complexity of the subsequent process.

Embodiment 1

[0015] Mix 30g of self-crosslinking single-component water-based polyurethane, 10g of pigment, and 2g of additives (including wear-resistant agent and water-repellent agent), and shear at high speed through the two-roller machine described in CN1693381A to a fineness of less than 5 μm, and add n-propylene Alcohol 25g, then make up to 100g with ethanol, until the mixture is completely dissolved to obtain ink.

Embodiment 2

[0017] Mix 20g of self-crosslinking single-component water-based polyurethane, 15g of pigment, and 2g of additives, and shear at high speed through the two-roller machine described in CN1693381A until the fineness is less than 5 μm, add 15g of n-propanol, and then make up to 100g with ethanol, After the mixture is completely dissolved, the ink is obtained.

Embodiment 3

[0019] Mix 35g of self-crosslinking single-component water-based polyurethane, 15g of pigment, and 5g of additives, and shear at high speed through the two-roller machine described in CN1693381A until the fineness is less than 5 μm, add 30g of n-propanol, and then make up to 100g with ethanol, After the mixture is completely dissolved, the ink is obtained.

Abstract

The invention relates to a low-temperature water-resistant ink for printing a PE (Poly Ethylene) shrink film. The low-temperature water-resistant ink is prepared from the following components in parts by weight: 20 to 35 parts of self-crosslinked monocomponent waterborne polyurethane, 10 to 20 parts of pigment, 15 to 30 parts of normal propyl alcohol, 2 to 5 parts of addition agent and the balance of ethyl alcohol. Aiming at the defects of the existing ink for printing the PE shrink film, the low-temperature water-resistant ink which is more suitable for printing the PE shrink film is obtained by adjusting ink components through a specific processing technology. When the low-temperature water-resistant ink is used for performing the printing, the ink curing performed by a drying room is not required, and the ink can be rapidly dried only under normal temperature, so that the production efficiency is improved. In addition, the low-temperature water-resistant ink is excellent in water resistance and abrasion resistance. Thus, the low-temperature water-resistant ink is suitable for popularization.

Description

technical field [0001] The invention relates to a low-temperature water-resistant ink used for printing PE shrink film, which belongs to the field of packaging printing. Background technique [0002] PE shrink film, also known as PE stretch film, is an industrial film product with high tensile strength, high elongation, good self-adhesiveness, and high transparency. It can be used for both manual stretching film and machine stretching film, and can be widely used in centralized packaging of various goods. PE stretch film is mainly composed of several different grades of polyethylene resin mixed and extruded. It has puncture resistance, super strength and high performance. It wraps the goods stacked on the pallet to make the package more stable, tidy and stronger. Waterproof, widely used in foreign trade export, papermaking, hardware, plastic chemical industry, building materials, food and medicine industries. [0003] However, the existing polyurethane inks have poor adhes...
