Description
Technical field
The present invention relates to trademark adhesives, more particularly to the trademark adhesive being attached on vial.
Background technology
As beverage in recent years, brewing industry rapidly develop, beverage, beer production line speed of production be increased to 4~6
Ten thousand bottles/hour, this requires trademark adhesive has, solid content is high, initial bonding strength is big, adhesive strength is high, the performance of good fluidity, with suitable
Answer the requirement of high speed machine adhesive label.Since living standards of the people are continuously improved, consumer taste also improves therewith, and people are to glass
The bottled beverage of glass, if fruit syrup, soft drink and beer will often be placed in ice water progress " iced ", make its it is more refrigerant can
Mouthful, thus trademark adhesive is also needed to preferable water resistance, a couple of days can be kept not fall mark in water.In addition, packing for convenience
Bottle recycles, and de- mark is also required to be easy.
Generally use casein, amylan and routine PVA glue both at home and abroad at present.Casein has initial bonding strength big, glues
The features such as relay is strong, and water resistance is good, but due to involving great expense, it is difficult to it promotes and applies.Amylan due to paste degree is big, fast drying,
Cheap, although can be used for mechanical labeling, brittleness is big after glued membrane drying, is easy mark, poor water resistance.It is usually used
Conventional PVA glue tack it is poor, leakage patch rate is high, poor water resistance.
Invention content
The purpose of the present invention is to provide a kind of low production cost, tack is big, water-tolerant, takes off the easy label of mark
Glue product.
The purpose of the present invention is what is realized by following measures：

Change one in copper, calcium acetate, zirconium carbonate ammonium, zirconium acetate, zirconium chloride, copper acetate, zinc acetate, zinc sulfate, zinc chloride, aluminum sulfate
Kind is a variety of.
In order to improve film forming, the flexibility of glue, above-mentioned trademark adhesive also includes dispersant, and the dispersant is urea, gathers
One or more in acrylamide, dicyandiamide, rhodanate, dispersant is with carboxylic vinyl alcohol system polymer weight ratio
0/10~20/10.
The pH value of above-mentioned trademark adhesive is adjusted to 7~10.
Above-mentioned trademark adhesive, can also add viscosity stabiliser, vinyl alcohol system polymer, antifoaming agent, preservative, plasticizer,
PH adjusting agent, rheology control agent etc..Each component can be added by random order.
Trademark adhesive made of the present invention is used for the stickup of glass bottle label, is preferably used in the stickup of beer bottle label.
Advantageous effect
