Abstract
FIELD: glue production. SUBSTANCE: proposed glue contains: ureaformaldehyde binder (as a base), sodium salt of carboxymethylcellulose (as a binder), ureaformaldehyde resin, caprolactam, oxalic acid, alkali and dextrine. Quantity of said components (mass parts) is as follows: 100, 0.3-4.0, 1.0, 0.05-0.7, 0.002-0.015, 0.0025-0.025. 1.0-6.0. Said components are mixed and allowed to stand within 1.0-3.5 h at 45-95 C. Proposed glue is stable within 12 months, creep limit being 28-56 Pa. Said glue may be used for glueing paper with cardboard, glass, metals, polystyrene and polyethylene. EFFECT: improves quality of glue. 3 cl, 2 tbl
Description
Изобретение относится к клеям, которые используют для наклеивания бумажных этикеток к стеклянной, пластмассовой, металлической таре, может использоваться на быстроходных автоматических линиях. The invention relates to adhesives that are used for gluing paper labels to glass, plastic, metal containers, can be used on high-speed automatic lines.
Целью изобретения является повышение стабильности клея и эффективности склеивания. The aim of the invention is to increase the stability of the adhesive and the bonding efficiency.
В качестве связующего используют продукт взаимодействия мочевиноформальдегидной смолы, капролактама, щавелевой кислоты и щелочи в массовом соотношении 1:(0,05-0,7):(0,002-0,015):(0,0025-0,025), который получают следующим образом. The binder used is the product of the interaction of urea-formaldehyde resin, caprolactam, oxalic acid and alkali in a mass ratio of 1: (0.05-0.7) :( 0.002-0.015) :( 0.0025-0.025), which is obtained as follows.
В реактор загружают мочевино-формальдегидную смолу, капролактам, дополняют щавелевую кислоту (рН остается в пределах 5,5-7,5), перемешивают при 20-60оС в течение 0,45-4,0 ч. После этого вводят щелочь.The reactor is charged with a urea-formaldehyde resin, caprolactam, complement oxalic acid (pH remains between 5.5-7.5) was stirred at 20-60 ° C for 0,45-4,0 hours. Thereafter, an alkali is administered.
Далее к готовому продукту взаимодействия добавляют натриевую соль карбоксиметилцеллюлозы и декстрин и выдерживают при 45-95оС и рН 7,5-9,0 в течение 1,0-3,5 ч.Next to the finished reaction product is added the sodium salt of carboxymethylcellulose and dextrin, and kept at 45-95 ° C and pH 7.5-9.0 for 1.0-3.5 hours.
В табл. 1 приведены конкретные примеры составов при различном содержании компонентов в клее и условиях приготовления клея. In the table. 1 shows specific examples of compositions with different components in the adhesive and the conditions for the preparation of the adhesive.
Характерные показатели полученных клеев приведены в табл. 2. Characteristic indicators of the obtained adhesives are given in table. 2.
