Problems solved by technology

[0004] Inorganic antibacterial agents such as silver-containing antibacterial agents, although the antibacterial effect is obvious, are obviously difficult to obtain in terms of cost and dispersion in water-based systems.
ZnO nanomaterials are also difficult to disperse in aqueous systems, and the antibacterial effect is not significant
Organic antibacterial agents such as allicin and other natural antibacterial agents, although they have excellent antibacterial properties, often have a pungent smell, and may remain on the surface of the food after prolonged contact with food, thus affecting the flavor of the food
The organic antibacterial agent with medicinal effect has a strong antibacterial purpose, but as a medicinal ingredient, it is not suitable for use in food packaging.

Embodiment 1

[0038] The water-based antifouling and antibacterial matrix resin is prepared as follows:

[0039] Take 100g of a mixed solvent of n-butanol and tert-butanol (mass ratio: 2:1), put it in a flask, heat it to 100°C while stirring, and start adding the mixture of reaction monomer, capsaicin-structure organic antibacterial agent and initiator dropwise solution. The reaction monomer is composed of 70g of methyl methacrylate, 34g of butyl acrylate, 12g of hydroxyethyl acrylate, 22g of acrylic acid, 22g of organic silicon monomer, 40g of organic antibacterial agent with capsaicin structure, and the initiator is 3g of azobisisobutyronitrile . Control the drop rate of the mixed reaction monomer and initiator so that the dropwise addition is completed within 4 hours. After the dropwise addition, keep warm for 2h, add 0.3g initiator, keep warm for another 2h. When the temperature is lowered to 60°C-70°C. Add 24g of amine stabilizer dimethylethanolamine and stir for 1h. Add 100 g of ...

Embodiment 2

[0043] The water-based antifouling and antibacterial matrix resin is prepared as follows:

[0044] Take 100g of a mixed solvent of n-butanol and isopropanol (mass ratio 4:1), put it in a flask, heat it to 90°C while stirring, and start adding the mixture of reaction monomer, capsaicin-structure organic antibacterial agent and initiator dropwise solution. The reaction monomer is composed of 60g of methyl methacrylate, 40g of butyl acrylate, 15g of hydroxyethyl acrylate, 21g of acrylic acid, 24g of organic silicon monomer, 40g of organic antibacterial agent with capsaicin structure, and the initiator is azobisisoheptanonitrile 1.5 g. Control the drop rate of the mixed reaction monomer and initiator so that the dropwise addition is completed within 4.5 hours. After the dropwise addition, keep warm for 2 hours, add 0.2 g of initiator, and keep warm for another 2 hours. When the temperature is lowered to 60°C-70°C. Add 20g of amine stabilizer ethanolamine and stir for 1h. Add ...

Abstract

The invention discloses waterborne ink with an antifouling antibacterial function and a preparation method thereof. The waterborne ink is prepared from 45 to 65 percent of waterborne antifouling antibacterial matrix resin, 10 to 25 percent of deionized water, 7 to 13 percent of co-solvent, 10 to 20 percent of pigments and fillers, 1 to 4 percent of diffusion agents, 0.2 to 0.8 percent of defoamingagents, 0.2 to 0.5 percent of pH stabilizer, and 0.6 to 2 percent of rheological functional aids. The antibacterial agent used in the ink of the invention is organic antibacterial agent with a natural capsaicine derivative structure, and has bionic characteristics. The antibacterial agent also has excellent antifouling antibacterial performance of the natural capsaicine, and is nontoxic and harmless to creatures and the environment like the natural capsaicine.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a water-based ink. Background technique [0002] At present, the vast majority of printing water-based inks for food packaging with antibacterial functions focus on the selection and use of antibacterial agents. The antibacterial agent is mainly added to the water-based ink formula by using a simple physical mixing method to endow the ink with an antibacterial function. [0003] In terms of antibacterial agents, some patents choose to use inorganic antibacterial agents such as silver-containing antibacterial agents and ZnO nanomaterials, and there are also patents to use organic antibacterial agents such as natural allicin, penicillin with drug effects, sulfadimethoxine, and so on. [0004] Inorganic antibacterial agents, such as silver-containing antibacterial agents, although the antibacterial effect is obvious, are obviously difficult to obtain in terms of cost and dispersion in ...
