Abstract
The adhesive for sticking labels mechanically is made up of water-soluble polymer, catalyst and viscosity regulater through heating and mixing in reactor, and features stable, high and adjustable viscosity, high initial adhesion, and resisting mechanical shear force. It is especially suitable for high speed sticking label machine to stick labels on beer bottle.
Description
The invention belongs to a kind of novel mechanical adhesive for sticking labels, particularly a kind of is matrix with the macromolecular material, is viscosity modifier with the thickening material, is the tackiness agent and the making method of additive with the mineral filler.
The production of the bottled beer of brew-house generally all adopts Labelling Machine realization mechanize to label.Along with the production-scale continuous expansion of brew-house, the decals speed of Labelling Machine also improves constantly.The general use of Labelling Machine has than the ram pump of big shearing force or the adhesive for labelling of toothed gear pump transfer of highly viscous.So then require tackiness agent storing the variation that its viscosity during the course should be not by a relatively large margin, thereby be convenient to the conveying of tackiness agent.Require tackiness agent in use not because of the shear action viscosity of pump descends significantly simultaneously, thereby make tackiness agent have bigger tack and enough resin addeds reach higher decals qualification rate.At present bottled beer with the mechanize adhesive for labelling from being divided into the serial two big classes of starch series and synthetic macromolecule substantially.The starch based tackiness agent is made the higher tackiness agent of viscosity easily, raises but exist the storage process medium viscosity, and the use medium viscosity descends and the shortcoming of easy moldy metamorphism significantly.Common high score subclass tackiness agent generally is difficult for making the higher tackiness agent of viscosity, in use exists the wire drawing phenomenon simultaneously.The appearance of above-mentioned certain situation all can influence the qualification rate and cause Labelling Machine to have to run slowly of labelling.
The purpose of this invention is to provide a kind of is matrix with the macromolecular material, is viscosity modifier with the thickening material, is the novel mechanical adhesive for sticking labels of additive with the mineral filler.It is higher and can regulate that the tackiness agent that adopts the inventive method to make has viscosity, good fluidity, and tack is big, characteristics such as anti-mechanical shear stress.Can change between the 20000mPas to 100000mPas by the viscosity that the consumption of thickening material is regulated tackiness agent, using with the Labelling Machine that adapts to different model.Can the use by mineral filler increase tackiness agent solids content, shorten the time of drying of the glue behind the decals and reduce cost.For Labelling Machine, also can not use mineral filler than lower velocity.
Macromolecular material in the adhesive for mechanized labelling of the present invention is to be that medium is to carry out condensation reaction under the effect of catalyzer to make with the mineral acid with water with polyvinyl alcohol and formaldehyde.This macromolecular material condensation material weight content in tackiness agent is formed is 6%～25%, and the thickening viscosity modifier that is adopted is a carboxymethyl cellulose.Different model according to the height and the Labelling Machine of the viscosity of carboxymethyl cellulose own, the weight content of the consumption of thickening material in the composition of tackiness agent is 1%-10%, general with use by carboxymethyl cellulose, arrive the viscosity adjustment of tackiness agent between the 40000mPas to 80000mPas comparatively general.Mineral filler can be selected for use such as talcum powder, wollastonite powder, various pH values such as kaolin are near the lower powdery mineral filler of neutral price, the consumption of mineral filler can reach according to the decals speed of Labelling Machine the requirement of time of drying is suitably selected for use, and the weight content of the consumption of general mineral filler in tackiness agent is formed is 0-25%.
Adhesive for mechanized labelling of the present invention is to make in the conversion unit that has heating and whipping appts.
The fs of preparation process is to add a certain amount of water in equipment, adds polyvinyl alcohol then and start to stir and be warming up to make polyvinyl alcohol dissolving fully in water more than 85 ℃.Subordinate phase is a condensation course, and a certain amount of mineral acid of adding and formaldehyde carry out condensation reaction and makes polyvinyl formal solution in polyvinyl alcohol water solution, and condensation temp should remain on more than 70 ℃, so that condensation reaction is carried out smoothly.Phase III is a N-process, neutralizes with alkaloids, regulates pH value between the 5-8.The quadravalence section is the viscosity adjustment process, by adding a certain amount of carboxymethyl cellulose and mineral filler, makes tackiness agent reach needed viscosity requirement.Just can obtain the higher liquid of vicidity of a kind of viscosity by above-mentioned technological process, be the present invention's tackiness agent.
The embodiment of invention:
Fetch water 400 kilograms, 45 kilograms of polyvinyl alcohol are put in the conversion unit, start to stir and heat to 95 ℃ to make it to dissolve fully.Treat that polyvinyl alcohol dissolves the back fully and adds 8 kilograms of hydrochloric acid and 10 kilograms of formaldehyde, under 90 ℃ temperature, carry out condensation reaction 60 minutes.Add 3 kilograms of caustic soda then and regulate pH values to 7, add 20 kilograms of carboxymethyl celluloses at last and add 30 kilograms of talcum powder, treat that carboxymethyl cellulose dissolves fully after, promptly make the present invention's tackiness agent.
