| titleOfInvention | Production method of Water soluble double sided coated tape, one sided coated tape and label |
| abstract | (1) The technical field to which the invention belongs:n n n Process for preparing water-soluble adhesives having oil properties and emulsion adhesives and properties equal or highern n n (2) Purpose of the invention:n n n The present invention is a pressure-sensitive adhesive for water-soluble double-sided tape, single-sided tape, labels, oil and emulsion adhesives used in the conventional OPP film and crepe paper tape is insoluble in water, so it is impossible to recycle, so as to compensate for this defect, By dissolving easily in alkali, the purpose is to overcome environmental pollution and to be 100% recycled.n n n (3) Composition of inventionn n n In the present invention, some of the cardyl group (-COOH) is left in the pressure-sensitive adhesive prepared using acrylic resin, ester rosin, polyol, and the like, which can be solubilized therein calcium hydroxide (KOH), lithium hydroxide (LIOH), sodium hydroxide (NAOH) Neutralization), while the existing product was neutralized with an amine-based light to obtain a water-insoluble coating, whereas a water-soluble coating was prepared to form a cured coating using an acid catalyst.n n n In the present invention, the acrylic resin has a molecular weight of 10,000-80,000 and is methyl methacrylate (MMA), butyl methacrylate (BAM), 2-ethylhexyl acrylate (2-EHA), styrene (SM), glycidyl meta 3 of acrylate (GMA), maleic acid (MALEIC ANHYDRIDE), fumaric acid (FUMARIC ACID), normal methacrylamide (NMAM), 2-hydroxyethyl acrylate (2-HEA), itaconic acid (ITACONIC ACID) It is a polymer obtained by using more than two and using an initiator in an alcohol solvent. The acid value is 10-50, and the solid content is 30-60%. As the initiator used herein, benzoyl peroxide (BENZOYLPEROXIDE), dietary reviewer peroxide (DI-TECT-BUTYLPEROXIDE), azoisobutyronitrile (AZOISOBUTYRONITRILE) and the like were used.n n n In addition, as a solvent, at least one of METANOL, ETANOL, BUTANOL, isopropyl alcohol (IPA) and isobutanol (ISOBUTANOL) was used, and the polymerization temperature was 60-100.n n n Polymerized in Figure C. The glass transition temperature (TG) of this acrylic resin was adjusted to between -50 and 30 degrees C.n n n It was.n n n An ester resin rosin having an acid value of 20-200 was used in the acrylic resin polymer obtained as described above. Thus, glycerin (GLYCERINE), propylene glycol (P.G.), PEG-200, PEG-400, CO-10,n n n The final acid value is 10-50 using one or more of POLYOL, such as SS-2046 and SS-205. Lithium hydroxide (LIOH), calcium hydroxide (KOH), sodium hydroxide (NAOH) for re-solubility of dried coatings After using one of these, the acid catalyst formic acid (FORMIC ACID), phosphoric acidn n n (PHOSPHRIC ACID), 1 sheet of paratoluene sulfic acid (PTSA) was used to form the final cured coating film.n n n (4) effects of the inventionn n n The present invention is the first water-soluble, pollution-free adhesive in Korea, and it is possible to recycle 100% of this waste tape at about 3,500 tons per year for only 3,500 tons of single-sided tape that is currently not recycled at all. Get savingsn n n In addition, by using 100% domestic raw materials, only double-sided tapes imported from domestic paper companies can obtain import substitution effect of about KRW 7.4 billion per year. Currently, only 3 companies, including 3M in the US, TESA in Germany, and NITO in Japan, produce only water-soluble double-coated tape products and supply them to the world. The present invention is the first in the world to produce and apply a water-soluble adhesive to labels.n n n This invention is equivalent to or superior in product power, but can be produced at half the level of foreign production in terms of price, resulting in superior international competitiveness in terms of price competitiveness. Specifically, December 31, 1994, the EU (European Union), which established the Directive on Packaging and Packaging Waste, and Japan, which is enacting the Container Packaging Recycling Act, and Japan and other countries aiming to improve the environment. It is expected to contribute greatly.n n n In addition, in case of existing tape, after waste box and waste sticker collection, air pollution and odor are generated when incineration and disposal of malignant waste due to inability to recycle OPP tape and release paper, which causes environmental pollution. And sticker on the siden n n By applying a water-soluble adhesive, 100% regeneration is possible, and thus an environmentally friendly effect can be expected without any pollution problem. |
