Embodiment 1

[0016] Add 100 grams of water into a four-neck flask, raise the temperature to 75°C, weigh 5 grams of K12 and dissolve it in 20 grams of hot water, mix MMA, BA, DAAM and MAA in a ratio of 1:1:0.1:0.1 and weigh 20g Add it into the K12 solution to stir and emulsify, then slowly add the above-mentioned emulsion into the four-necked flask, and at the same time dissolve the initiator APS in an appropriate amount of water, add the initiator to the above solution, and the mass percentage of the initiator APS is the above-mentioned 1~2% of the solution mass; gradually add it dropwise into a four-neck flask, and finish the drop within 40-50 minutes. The reaction is carried out under normal pressure for 1 hour. After the reaction, the liquid becomes transparent and has blue opalescence, then heats up to 85°C ;

[0017] BA, MMA, MAA, DAAM and DDM are mixed and emulsified according to a mass ratio of 1:1:0.1:0.1:0.05, and then 80g is added dropwise to the above-mentioned four-necked flask...

Embodiment 2

[0021] The invention provides a kind of preparation method of water-based OPP packaging film gravure ink connection emulsion, comprising the following steps:

[0022] 1) Add 100 parts by weight of water into a reaction vessel and raise the temperature to 70~80°C as base water;

[0023] 2) Dissolve 5 parts by weight of sodium dodecylsulfonate into 20 parts by weight of hot water at 60-85°C, and mix methyl methacrylate, butyl acrylate, diacetone acrylamide and methacrylic acid according to 1 : 1:0.1:0.1 mass ratio after mixing, weigh 20 parts by weight and add to sodium dodecylsulfurate solution, stir and emulsify; then set aside.

[0024] 3) Slowly add the emulsion in step 2) into the four-necked flask, and at the same time dissolve the initiator ammonium persulfate in water. The mass percent concentration of the ammonium persulfate solution is 10-40%. agent, the mass percentage of the initiator is 1-2% of the above-mentioned solution mass; slowly add it into the above-mention...

Abstract

The invention discloses a preparation method for gravure ink connecting emulsion for a water-based OPP packaging film. The preparation method comprises the following steps: adding water into a reaction container, heating the water as bottoming water, and adding methyl methacrylate, butyl acrylate, diacetone acrylamide and methylacrylic acid into a dodecyl sodium thionate solution to emulsify; then, adding the emulsified solution into the bottoming water, adding an initiator, and heating after reacted liquid is transparent and has blue opalescence; and emulsifying and adding butyl acrylate, methyl methacrylate, methacrylic acid, diacetone acrylamide and dodecanethiol into the reaction container, then, adding the initiator, cooling, adding hydroxyethyl acrylamide, carrying out oxidation and reduction after preserving the heat to remove smell, adding adipic dihydrazide after cooling, and cooling and discharging after reaction is completed, thereby obtaining a semi-transparent emulsion sample with blue light. The obtained emulsion is relatively small in emulsion particle size, is uniform in arrangement, and is circular in surface. The emulsion is prepared into gravure ink for the packaging film, so that drying is quick and sticking resistance is good.

Description

technical field [0001] The invention belongs to the field of chemical industry, and relates to a water-based environment-friendly packaging material, in particular to a method for preparing a water-based OPP packaging film using a gravure ink connection emulsion. Background technique [0002] In my country's food packaging industry, due to the extensive use of oil-based ink printing, a large amount of organic petroleum solvents will be used in the printing process, which will cause serious pollution to the environment, and these solvents will remain on the packaging film, which will cause harm to the human body after contact; foreign countries Developed countries have begun to try to use ink instead of ink for printing to reduce harm to the human body and environmental pollution. Ink uses water as a diluent, which is environmentally friendly without any air pollution. Contents of the invention [0003] Aiming at the above-mentioned technical problems in the prior art, the i...
