Description
Technical field
The present invention relates to a kind of production method of label glue, relate in particular to a kind of production method of modified casein label adhesive.
Background technology
Adhesive for label is the important link of packing of product image appearance, particularly the decals of bottled product requires higher, as developing rapidly of China's brewing industry, annual beer production reaches more than 2,000 ten thousand tons, each beer production producer is in order to enlarge output and to improve product specification, what have is transformed homemade trade mark Labelling Machine, the external advanced packaging production line of the introduction that has, not only the decals machine speed by original per hour several thousand bottles bring up to several ten thousand bottles, and adopt aluminium foil and tinfoil paper one after another as sealing and the trade mark label, requirement to label glue is also more and more higher, and initial bonding strength is eager to excel, it is high that viscosity is wanted, the strong label glue of over-all properties such as rate of drying is fast more and more are subjected to people's attention.
At present, the used label glue of mechanize decals cementing agent of China's drinks and beverage mainly contains several starch, modified starch adhesive, mainly comprises the dextrin glue stick, starch adhesive, modified starch tackiness agent; Polyvinyl alcohol (PVA) formal and modified PVA formal glue stick; The synthetic macromolecule tackiness agent mainly comprises the acrylate copolymer emulsion tackiness agent, polyvinyl alcohol and modified polyvinyl formal tackiness agent and polyacrylonitrile hydrolyzed thing tackiness agent; Polyamide binder, polyvinyl acetate adhesive, carboxymethyl cellulose gum stick are also arranged; Label glue such as casein glue A.
The shortcomings such as requirement of growing, easily go mouldy, can not satisfy high-speed labeling machine the set time on bottle owing to common treated starch label glue have influence on the shelf-time and the image appearance of commodity, so its suitability more and more is restricted; Polyvinyl alcohol label glue (development [J] of the military .PVF type of Chen Yuan high speed adhesive for labelling. Chinese tackiness agent, 1998,4 (7): 17-18.), its initial bonding strength is too little, the displacement of trade mark is serious, not only can not satisfy the requirement of high-speed labeling machine, and in the phenomenon that occurs than cold weather label glue easy freezing using; Then because over-all properties is poor, and rate of drying is slow, the storage time is short for the tackiness agent of polyamide binder, polyvinyl acetate adhesive, carboxymethyl cellulose class, and difficulty or ease adapt to the requirement of modern high-speed labeling machine.
Because all there are the shortcomings such as demand that poor water resistance, rate of drying are slow, can not satisfy industrialized high speed labelling machine in above-mentioned label glue, therefore people's direct production casein type glue arranged also.Casein glue is a kind of novel environment-friendly polymer binder, and is nontoxic, tasteless, odorless, have higher tack, curing speed is fast, and cohesive force is strong, have good anti-frozen water and moisture resistance, be suitable for the high speed price labeling, but the cost of casein glue A is then too high aspect industrial applications.Simultaneously, the glue on the existing market mostly contains the poisonous ion of heavy metal, and as lead sulfate, the poisonous easy pollution substance of plumbous class such as plumbic acetate easily pollutes environment.
Summary of the invention
Technical problem to be solved by this invention provides the production method of the modified casein label adhesive that a kind of cost is low, initial bonding strength is strong, the shelf lives is long, rate of drying is fast, refrigeration property is good.
For addressing the above problem, the production method of a kind of modified casein label adhesive of the present invention may further comprise the steps:
(1) polyvinyl alcohol is dissolved in water under 90～95 ℃ temperature, behind insulation 50～60min, is cooled to 70～75 ℃, obtain polyvinyl alcohol solution;
