Abstract
The present invention relates to a water-resistant adhesive for labels, which is prepared from 5 wt% to 30 wt% of starch, 3 wt% to 20 wt% of casein and other various additives. The present invention has the characteristics of high solid content, strong initial adhesion, strong cementing power, good flowability, low cost, etc. After being soaked in ice water for more than 20 hours, the label still keeps unwounded performance and is suitable for high-speed equipment for sticking the labels.
Description
The present invention relates to the tackiness agent prepared with starch, casein and other additive, particularly relate to a kind of preparation of water-proof adhesive for label.
In recent years, brewing industry obtains develop rapidly, and the sticking mark speed of mechanize is also more and more faster, and is also more and more higher to the requirement of adhesive for label.Because improving constantly of living standards of the people, people consume grade and also improve thereupon.To the beverage of glass bottle, often all to be placed in the frozen water as fruit syrup, soft drink and beer and to carry out " icing ", make it refrigerant more good to eat; Thereby beer label glue not only need have the solid content height, tack is big, cohesive force is strong, good fluidity, to adapt to the requirement of high speed machine adhesive label, but also it is good to have a water resistance, and satisfying people when beverage carries out " icing ", label remains intact the requirement do not fallen.Price is also cheap simultaneously.What generally use at present both at home and abroad is casein, dextrin amylan and PVA glue, and characteristics such as wherein to have a tack big for casein, and cohesive force is strong, and water resistance is good are particularly suitable for the high speed machine adhesive label, but owing to involving great expense, are difficult to generally apply; With yellow starch gum, white dextrin is the tackiness agent of raw material manufacturing, because the paste degree is big, dried solid fast, inexpensive, also can be used for mechanical decals, and shortcoming is that the dried solid back of glued membrane fragility is big, falls to mark easily; And the at present domestic PVA machinery decals glue that generally uses because its tack is little, leaks subsides rate height, and the label after the stickup is done solid slower, and label is easy to displacement, often causes not meeting national standard, and is unable to undergo frozen water and soaks.The tackiness agent that U.S.4464202 adopts treated starch to make, performance is not poor, but can not be water-fast.CN1059352A adopts starch and organic polymer synthetic label glue also not to have water resistance, the label glue that J.P5-230433 adopts casein and organic polymer to form had both adapted to the requirement of mechanical decals, water tolerance is arranged again, but cost too costliness be not suitable for China's national situation.
The objective of the invention is to overcome above-mentioned tackiness agent shortcoming, be developed into a kind of tack and anti-outlet capacity of making every effort to improve tackiness agent, reach the solid content height, tack is big, cohesive force is strong, good fluidity, cost are low, can waterproof, the water-resistant adhesive for label of easily removing under proper condition again.
The present invention is to be matrix with starch and casein, with alkaline substance, flowing agent, water repellent agent, linking agent, shape-intensifying agent, sanitas, a kind of new mechanical adhesive label tackiness agent that auxiliary such as mould inhibitor and tensio-active agent is made, because adhesive components is selected for use appropriately, it is suitable to create conditions, and makes water-resistant adhesive of the present invention have the solid content height, tack is big, cohesive force is strong, good fluidity, the label ability of pasting is the frozen water immersion more than 20 hours, can clean easily under proper condition again, characteristics such as cheap, this tackiness agent can use under original labeling technique and the returnable bottle cleaning situation not changing, having improved decals qualification rate and anti-outlet capacity greatly, is a kind of ideal adhesive for label.
The used starch of water-resistant adhesive for label of the present invention can be various natural plant starch, Sumstar 190 preferably, and treated starches such as cationic quaternary amine starch ethers and hydroxypropyl Sumstar 190 ether, its weight content in component is 5～30%.
The used casein resin of the present invention does not have special restriction, rough or purified casein glue all can, its weight content in component is 3～20%.The present invention adopts following compound method can obviously improve water resistance, promptly adds Ca (OH) when casein dissolves

2, CuSO
4, ZnSO
4, ZnAc
2, in the water-proofing agent such as ZnO one or both, weight content is 0.5～10%.
In order to improve the flowability of tackiness agent, need to add flowing agent, one or both in urea of the present invention, Dyhard RU 100, thiocyanic acid amine, the ammonium nitrate, the weight content in component are 5～30%.
For the cohesive force that increases tackiness agent also need add linking agent, linking agent can be selected boric acid, borax, formaldehyde, oxalic acid, oxalic dialdehyde etc. for use, and the weight content in component is 0.1～5%.
Need add suitable softening agent, sanitas, mould inhibitor, viscosity stabilizer, defoamer, tensio-active agent, deodorant essence etc. in addition.This is not had special requirement, and those of ordinary skill in the art all can handle.
The manufacturing of water-resistant adhesive for label of the present invention is not particularly limited, and starch and other auxiliary can be added in the caseic aqueous solution that is prefabricated into by alkaline substance, stirs, heats, and reaction forms.This tackiness agent is suitable for the label of sticking glass beverage bottle, is particularly suitable for pasting the label of Beer Bottle.
The solid content of water-resistant adhesive for label of the present invention is 20～60%, be preferably 30～50%, requirement on different decals mechanical speeds and producer is decided, by the requirement of high speed machine adhesive label, under the barbola work temperature condition, tackiness agent viscosity is generally 5000～100000mPas, is preferably 20000～70000mPas.
