Abstract
The invention belongs to the technology application field of adhesive and particularly relates to a preparation method of a waterproof label adhesive. The preparation method comprises the following steps: mixing a certain amount of polyvinyl alcohol, emulsified silicon oil and water to fully stir, heating and dissolving to obtain polyvinyl alcohol solution, adding initiator; mixing a certain amount of acrylic acid, butyl acrylate, styrene, acrylamide, ammonium persulfate and water, emulsifying to obtain emulsion; then slowly adding the emulsion in the polyvinyl alcohol solution, heating, keeping the temperature, then cooling to the room temperature; and finally adding zinc oxide and sodium hydroxide, fully stirring, adjusting the pH value to 6-7 and adding defoaming agent and preservative to obtain homogeneous paste, namely the label adhesive. The adhesive has the advantages of ice water resistance, low cost and the like.
Description
Technical field
The present invention relates to a kind of preparation method of watertight label adhesive.The invention belongs to the adhesive technology Application Areas.
Background technology
The trade mark adhesive that the glass bottle packing of product of China is at present used has starch based, polyvinyl formal class, casein glue etc.Along with the development of domestic beer industry, starch based in the past and polyvinyl formal class trade mark tackiness agent exist bonding strength low, easily go mouldy, water tolerance is bad, be not suitable for refrigerator-freezer deficiency such as deposits.
In addition, beer line production rate also requires label glue to have good tack and high speed operation, and starch based and polyvinyl alcohol tackiness agent all do not adapt to the requirement of high-speed production, so beer producer turns to use casein type tackiness agent gradually both at home and abroad.Casein type tackiness agent has good tack, water tolerance and neutralizing treatment, but its cost is high always, adds to lack relevant production technology, and domestic high speed beer production line and use tinsel are done the producer of label glue, depend on import mostly.
Therefore develop the adhesive for labels product that not only meets production requirement but also can reduce production costs, become the focus of current research.The preparation of modified water-tolerant polyvinyl alcohol adhesive for labels not only initial cohesiveness good, have excellent water-resistance, and environmental protection, cost is lower, can meet the requirement of beer production producer.
Summary of the invention
The preparation method who the purpose of this invention is to provide a kind of watertight label adhesive.
Technical scheme of the present invention is: earlier a certain amount of polyvinyl alcohol, silicone emulsion, water are mixed, after fully stirring, slowly be heated to 80-90 ℃ of insulation 30min, be cooled to 70 ℃ then, obtain polyvinyl alcohol water solution, add initiator ammonium persulfate.Simultaneously a certain amount of vinylformic acid, butyl acrylate, vinylbenzene, acrylamide, ammonium persulphate, silicone emulsion, water mixing and emulsifying 30min are got emulsion.Again emulsion slowly being added in the polyvinyl alcohol water solution, be warming up to 80-90 ℃. insulation 1-2h. reduces to room temperature.Add zinc oxide and sodium hydroxide at last, fully stir 15min, transfer pH to 6-7, it is adhesive for labels that adding defoamer and sanitas obtain the homogeneous soup compound.
In the said process, each weight percent of forming is that polyvinyl alcohol 10.7%-12.1%, silicone emulsion 0.3%-0.4%, vinylformic acid 2%-3%, butyl acrylate 0.3%-0.4%, vinylbenzene 0.7%-1.2%, acrylamide 0.85%-1%, ammonium persulphate 0.07%-0.08%, water 70%-85%, zinc oxide 0.3%-0.5%, sodium hydroxide are transferred pH to 6-7 in right amount.Defoamer is a propyl carbinol, and weight percent is 0.02%-0.2%, and sanitas is a Sodium Benzoate, and weight percent is 0.01%-0.1%.
Embodiment
Following example will specify working method of the present invention, but can not be as limitation of the invention.
Example one
Earlier polyvinyl alcohol 100g-150g, silicone emulsion 2-3mL, water 1000g are mixed, after the stirring, slowly be heated to 80-90 ℃ of insulation 30min, be cooled to 70 ℃ then, obtain polyvinyl alcohol water solution, add initiator ammonium persulfate 0.3g-0.5g.Simultaneously vinylformic acid 30g-35g, butyl acrylate 5g, vinylbenzene 10g-15g, acrylamide 12g, ammonium persulphate 0.5g, silicone emulsion 2mL, water 20-30mL mixing and emulsifying 30min are got emulsion.Again emulsion slowly being added in the polyvinyl alcohol water solution, be warming up to 80-90 ℃. insulation 1-2h. reduces to room temperature.Add zinc oxide 4g-6g at last, fully stir 15min, sodium hydroxide is transferred pH to 6-7, adds defoamer 0.3mL-3mL, sanitas 0.15g-1.5g, and obtaining the homogeneous soup compound is adhesive for labels.
