Embodiment 1

[0023] The preparation method of resin coating film comprises following steps:

[0024] 1) Add methyl methacrylate, butyl acrylate, acrylic acid and hydroxyethyl acrylate to the reaction kettle, and polymerize to obtain a mixed monomer solution for later use;

[0025] 2) Add azobisisobutyronitrile and diacetone acrylamide to the mixed monomer solution obtained in step 1), and stir at a temperature of 25°C at a speed of 350-500r / min for 20min to obtain a primary solution for later use;

[0026] 3) Take a flask, add oxyethylene ether, polyoxyethylene glycol alkyl ester, propylene glycol methyl ether acetate and dimethylformamide into the flask, mix to obtain a solvent solution, heat to 75~90°C, and then Add the primary solution obtained in the step 2) to the solvent liquid at a constant speed, the dropping time is controlled at 2h~4h, the reaction temperature during the dropping is controlled at 75~90°C, and the temperature is kept at 80~90°C after the dropping is completed , s...

Abstract

The invention discloses a preparation method for a resin coating film. The preparation method includes the steps of: (1) adding methyl methacrylate, butyl acrylate, acrylic acid and hydroxyethyl acrylate into a reaction kettle to carry out polymerization to prepare a mixture monomer solution; (2) adding azodiisobutyronitrile and diacetone acrylamide to the mixture monomer solution with stirring to obtain a primary solution; (3) adding propylene glycol monomethyl ether acetate, dimethylformamide and the like to a flask, and mixing the components to obtain a solvent, and then dropwise adding the primary solution to the solvent at constant speed and allowing the solution to stand, thus preparing a crude product; (4) adding triethylamine, ammonia water, distilled water and a pH regulator to the crude product and uniformly mixing the mixture to form aqueous acrylic resin; (5) preparing a clean polyfluortetraethylene plate; and (6) coating the polyfluortetraethylene plate with a proper amount of the aqueous acrylic resin to form the film. The resin coating film has convenience in test on performances such as water absorption, crosslinking degree, hardness and the like of the aqueous acrylic resin, thereby obtaining accurate data.

Description

technical field [0001] The invention relates to the technical field of ink, in particular to a preparation method of a resin coating film. Background technique [0002] With the increasing awareness of environmental protection, especially in the fields of food, children's toys and medical packaging, water-based inks will eventually replace solvent-based inks. However, the solvent water of water-based ink is a polar material, and it is usually difficult to wet the surface of plastic films such as PP, PE, OPP, PO, etc. with low polarity. In order to improve the adhesion on the plastic film, it is necessary to consider the bonding force between the binder and the plastic film when configuring water-based ink. Due to the advantages of light color, high transparency and good weather resistance, water-based acrylate resin is widely used in the field of product packaging. At present, water-based acrylic resins usually use high-temperature cross-linking and curing to improve the a...
