Embodiment 1

[0102] Example 1. Preparation of a paper coating material comprising polyvinyl alcohol and copolymerized therein to obtain a copolymer emulsion of a silicon-based polymer and an acrylic polymer

[0103] While maintaining the temperature of the reactor containing 120 g of deionized water at 60° C., 40 g of methyl methacrylate, 44 g of butyl acrylate, 1.0 g of methacrylic acid and 1.0 g of hydroxyethyl methacrylate were added to the reactor. Blended acrylic monomer mixture. To this was added 0.2 g ammonium persulfate, 0.4 g dibutyltin dilaurate (DBTDL), 1.0 g octylphenol ethoxylate (OP), 0.8 g sodium dodecyl sulfate (SDS) and 0.2 g Na 2 CO 3 .

[0104] When the temperature of the reactor reached 80°C, ammonium persulfate was added. After 10 minutes, the silicon-based monomer was introduced into the reactor at a uniform rate over 2 hours. The amount of the silicon-based monomer is controlled so that the weight ratio of the acrylic polymer to the silicon-based polymer in the c...

Embodiment 2

[0107] Embodiment 2. The preparation of coating material and the coating of base paper for cups

[0108] Packaging paper was coated with the paper coating material prepared according to the preparation method of Example 1. Base paper for cups manufactured by Hansol Paper Co., Ltd. (trade name: FAB350, basis weight: 350g / m 2 ). Using a water-soluble coating solution in which 35.0% by weight of the paper coating material of the present invention, 0.2% by weight of silicon dioxide, and 64.8% by weight of water were mixed, the coating was carried out at 9.5 g / m using an air knife coating device. 2 One side coating is performed.

Embodiment 3

[0109] Example 3. Coating of Base Paper for Cups

[0110] Using the same cup base paper and coating solution as in Example 2, using a rod coating device at 8.5g / m 2 One side coating is performed.

Abstract

Provided are a paper coating material having environment-friendly, water-proof, and oil-proof properties, and a method of manufacturing the same. The paper coating material includes a copolymer emulsion in which a silicon-based polymer and an acryl-based polymer are copolymerized, the copolymer emulsion having the weight average molecular weight of 100,000 to 200,000, and a colloidal aqueous solution of gelatinized polyvinyl alcohol to be mixed with the copolymer emulsion. The environment-friendly paper coated with the environment-friendly coating material according to the present invention isexcellent in water-proof, oil-proof and heat sealing properties, harmless to the human body when used for packaging food, and recyclable as a raw material for making paper. It is also biodegradable and therefore, environment-friendly.

Description

technical field [0001] The present invention relates to a paper coating material and a preparation method thereof, more particularly, to a paper coating material which is recyclable, thus environmentally friendly, and has moisture-proof, water-proof and oil-proof properties and a preparation method thereof. Background technique [0002] In 1907, Houg Moor from the United States invented paper cups and declared that only disposable cups can protect humans from bacteria. Since then, people have used paper cups for more than 100 years because of their hygiene and convenience. [0003] Paper food containers such as paper cups should be waterproof due to their basic function of holding water and beverages in them. Currently, most paper cups are manufactured by coating or laminating polyethylene (PE) on paper. Paper or paper cups coated with polyethylene have excellent waterproof properties and are conducive to mass production. [0004] Actually, however, there are many problem...
