Problems solved by technology

At present, most retort-resistant inks in China are made of harmful solvents (such as benzene), and their volatile substances will remain on the surface of the packaging, and will penetrate into the other side of the packaging, that is, the food layer during cooking, so serious affect food quality
In addition, the stability of the existing ink also needs to be further improved

Embodiment 1

[0016] A retort-resistant environmental protection ink, which consists of: 25 parts (weight) of silicone modified polyamide resin (number average molecular weight is about 200,000), 10 parts of acrylic resin (number average molecular weight 5000), 20 parts of organic red pigment, 15 parts of absolute ethanol, 12 parts of n-propyl acetate; 8 parts of propylene glycol; 1 part of citric acid, 3 parts of dispersant (modified polysiloxane), 3 parts of leveling agent (polydimethylsiloxane), 1 part wax.

[0017] The above ink is prepared by the following method: according to the formula, mix absolute ethanol and propylene glycol in proportion, add silicone modified polyamide resin, acrylic resin and organic red pigment while stirring, stir at high speed for 15 to 30 minutes, and then sand mill Machine grinding and dispersion, when the fineness reaches below 5 microns, add the remaining components and stir to obtain the ink product.

Embodiment 2

[0019] A retort-resistant environmental protection ink, which consists of: 30 parts (weight) of silicone modified polyamide resin (about 300,000 number average molecular weight), 8 parts (weight) of acrylic resin (number average molecular weight 10000), 20 parts of organic yellow pigment, no 12 parts of water ethanol, 12 parts of n-propyl acetate; 11 parts of propylene glycol; 1 part of citric acid, 3 parts of dispersant (modified polysiloxane), 3 parts of leveling agent (polyacrylate copolymer).

[0020] The ink of this example can be prepared according to the same method as Example 1.

Embodiment 3

[0022] A retort-resistant environmental protection ink, which consists of: 34 parts (weight) of silicone modified polyamide resin (about 400,000 number average molecular weight), 8 parts of acrylic resin (number average molecular weight 10000), 20 parts of organic phthalocyanine blue pigment , 12 parts of absolute ethanol, 10 parts of n-propyl acetate; 10 parts of propylene glycol; 1 part of citric acid, 2 parts of dispersant (polycarboxylate amine salt), 3 parts of leveling agent (polyacrylate copolymer).

[0023] The ink of this example can be prepared according to the same method as Example 1.

Abstract

The invention relates to a steam-resistant environment-friendly ink, wherein the aqueous ink comprises following components by weight proportion: 25-35 parts of organic silicon modified polyamide resin, 8-12 parts of acrylic resin, 20-35 parts of paint, 10-20 parts of absolute ethyl alcohol, 10-15 parts of n-propyl acetate, 8-12 parts of propanediol and 0.8-1.2 parts of citric acid. The ink of the invention can satisfy the process of being boiled at the temperature of 100 DEG C for 45min and at the temperature of 121 DEG C for 30min, is suitable for the requirements of heat preservation and sterilization of the beverage package and can be used for compound boiling and also surface printing of PET and NY; the ink has excellent solvent releasing property and low residue without odor; in addition, the ink has strong adhesive force and good anti-freezing performance, heat resistance and stability.

Description

technical field [0001] The invention belongs to the field of inks, in particular to a retort-resistant ink. Background technique [0002] Inks used in food packaging are usually required to be environmentally friendly and non-toxic. In addition to being environmentally friendly and non-toxic, inks used in food packaging such as sausages and hams are also required to meet the requirements of boiling and steaming. At present, most retort-resistant inks in China are made of harmful solvents (such as benzene), and their volatile substances will remain on the surface of the packaging, and will penetrate into the other side of the packaging, that is, the food layer during cooking, so serious affected food quality. In addition, the stability of the existing ink also needs to be further improved. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a retort-resistant environmental protection ink in order to overcome the def...
