Abstract
The present invention is a kind of adhesive for mechanized labelling, mainly is made of compositions such as starch, catalyzer, tackifier, linking agent and water.Above-mentioned substance is placed conversion unit, and heating and stirring make it become the toughness material.The advantage of tackiness agent of the present invention is the solids content height, tack is big, bonding strength is high, raw material sources are easy, the label of returnable bottle is easy to clean and remove, and has free of contamination characteristics in nontoxic, free from extraneous odour, the production process.
Description
The invention belongs to a kind of novel mechanicalization card label and stick with glue agent, particularly a kind of is matrix with the chemically modified starch, is the tackiness agent and the making method of additive with tackifier and linking agent.
The production of beer and similar bottled drink generally all need be adopted Labelling Machine to carry out mechanize and label.Along with the production-scale continuous expansion of brew-house, the decals speed of Labelling Machine also improves constantly.And the tackiness agent of labelling that uses at present mostly adopts the starch paste that adds a small amount of caustic soda or adopts the dextrin of single-component to make.Because of leaking label displacement behind the higher and decals of decals rate in the poster process that uses at present, thereby the phenomenon that causes not meeting the decals position of national Specification takes place.
The purpose of this invention is to provide a kind of is matrix with the chemically modified starch, is the novel mechanical adhesive for sticking labels of additive with tackifier, linking agent and sanitas.Because the suitable selection of catalyzer and the use of additive in the starch conversion process, adhesive for mechanized labelling of the present invention has the solids content height, tack is big, bonding strength is high and the characteristics of good fluidity.This tackiness agent can be under the situation that does not change original labeling technique and returnable bottle cleaning, bigger raising the qualification rate and finishing preferably of decals label technological process as figure.
Adhesive for mechanized labelling of the present invention is to be matrix with the chemically modified starch.Its starch can be various natural plant starch, and the weight content of starch in composition is 20～80%.Add tackifier in the dissolution process of technology, tackifier can be polyacrylic acid, polyacrylamide, its tackify effectively to contain the weight content of thing in composition admittedly be 0.01～1%.Add acid catalyst and starch in the chemical modification of starch process of technology, acid catalyst can be commercial acids such as hydrochloric acid, oxalic acid, nitric acid, phosphoric acid.The weight content of its acid catalyst in composition is 0.1～5%.Add linking agent in the cross-linking process of technology, linking agent can be borax, boric acid, and the weight content of its linking agent in composition is 1～10%.What special requirement sanitas is not had, and as using or accumulating lower season in temperature, adding preservative agent is not to reduce production costs.
It is to make in the equipment that has heating and stir that mechanize glue label of the present invention sticks with glue agent.
The fs of preparation process is under 0 ℃～140 ℃ temperature, adds a certain amount of water and tackifier in equipment, starts stirring, makes the tackifier dissolving; Subordinate phase is to add acid catalyst and starch, make starch under the acid catalyst effect in tackifier solution hydrolysis and with the tackifier blend.Its temperature of reaction is 30 ℃～140 ℃, and this stage is the chemical modification stage of starch.And after starch expands, reconcile pH value to neutral with alkaloids, to end the hydrolysis of starch.Phase III is to add linking agent and above-mentioned treated starch to carry out crosslinkedly, and finally makes liquid of vicidity, is this tackiness agent.As using or accumulating higher season, can add sanitas simultaneously in the preparation phase III in temperature.
The present invention's embodiment:
Fetch water 100 kilograms, 0.7 kilogram of powdered polypropylene acid amides starts stirring under 80 ℃ of temperature, make the polyacrylamide amine solvent.After treating fully dissolving, add 90 kilograms of 2 kilograms of hydrochloric acid and starch, be warming up to 90 ℃, make starch under the hydrochloric acid catalyst effect hydrolysis and with the polyacrylamide solution blend.About 60 minutes of its process.Add then caustic soda neutralize and regulate pH value for neutral to stop the hydrolysis of starch.Add at last 4 kilograms of 4 kilograms of linking agent boraxs and boric acid carry out crosslinked, about 20 minutes of this cross-linking process.Crosslinking process promptly makes this tackiness agent after finishing.
Claims (4)
