Abstract
The invention relates to the field of the high milecular polymerization emulsion type glue water, in particular to a method for preparing water-soluble hot melt adhesive glue water, The method for preparing the water-soluble hot melt adhesive glue water is characterized in that filling materials and water with calculated amount are added into a blending pan; a stirring motor is started to performrapid stirring; auxiliary agents are added into the blending pan, such as an anti-foaming agent, an anti-mildew agent, an emulsifying agent, a dispersing agent, etc.; after being stirred for a periodof time, the stirring speed is slowed down, EVA emulsion is added; then an anchoring agent is added; and the water-soluble hot melt adhesive glue water is prepared through even stirring. Compared with the prior art, the method has the advantages of simple process and low cost, and the study keeps the development direction of the domestic international high milecular polymerization on track, is market oriented, fills the gap in our country, meets the urgent requirements of the market, can conform to the requirement of the production process in the industrialization, can produce novel hot melt adhesive glue water which is free of environmental pollution, three-waste pollution and aquosity, does not contain organic solvent, is nontoxic and non-explosive and has no danger for combustion, therefore, the study is worthy of popularization and application.
Description
[technical field]
The present invention relates to technology high molecular polymerization emulsion-type glue field, specifically provide a kind of preparation method of water-soluble hot-melt adhesive glue.
[background technology]
Along with China's medicine equipment and foodstuffs industry fast development, very needing a kind of is the emulsion-type heat-sealing chewing-gum water that base-material is further processed with the ethylene-vinyl acetate copolymer resins.Disposable medical treatment product were to pass through strict sterilising packaging before syringe, transfusion device, hospital gauze, sterilization cotton etc. are in arriving medical personnel's hand.This wrapping material, one side is transparent plastics film or composite membrane, another side is to be printed on name of product, the paper of comments such as specification brand, this paper is easily with pulling brokenly.
Plastics film is PVC or PE composite membrane normally, make paper and PE composite membrane bonding, and this paper will pass through special processing treatment in advance, normally is coated with one deck hot-melt adhesive glue.This glue is domestic, and what oneself can produce preparation is to be solvent with toluene, heating for dissolving EVA hot-melt resin, add petroleum resin, Microcrystalline Wax, terpine resin again, rosin etc. are composite to form, because of there being a large amount of toluene to exist, so be non-environmental type glue, do not welcome by the direct labor, do not accepted by external businessman yet.
[summary of the invention]
Purpose of the present invention overcomes the defective of prior art, and a kind of preparation method of novel aqueous hot-melt adhesive glue is provided, and viscosity height, thermally melting are strong, fill a hole in the market, and satisfy enterprise demand.
For achieving the above object, design a kind of preparation method of water-soluble hot-melt adhesive glue, it is characterized in that in ingredients pot, add the filler and the water of calculated amount, start stirring motor, stir fast, add auxiliary agents such as defoamer, mould inhibitor, emulsifying agent and dispersion agent, wait to stir after for some time, stirring velocity slows down, add the EVA emulsion, and then add tackifier, stir and make.
Mould inhibitor adopts organosilicon quaternary ammonium salt as mould inhibitor, described organosilicon quaternary ammonium salt preparation is in there-necked flask, load onto thermometer, reflux condensing tube and stirring motor, the trichlorosilane that adds specified amount, chlorallylene and catalyzer back flow reaction, finish until reaction, distillation then, collect the intermediates trichlorosilane, then allyltrichlorosilane is carried out alcoholysis reaction and make the allyl group trialkoxy silane, again the allyl group trialkoxy silane is dropped in the there-necked flask, and long chain alkyl dimethyl amine and solvent are added in the there-necked flask, load onto thermometer, stirring motor and reflux condensing tube, heating, the stirring and refluxing reaction finishes until reaction, promptly make the organosilicon mould inhibitor, the consumption of organosilicon mould inhibitor is between the 1-10000ppm.
Defoamer adopts silicone antifoam agent as defoamer, described silicone antifoam agent can prepare as follows, with hydrogeneous cyclotetrasiloxane, octamethylcyclotetrasiloxane, hexamethyldisiloxane and appropriate amount of catalysts, drop in the there-necked flask, load onto thermometer, stirring motor and prolong, condensation reaction is carried out in heating, after reaction finishes, remove catalyzer and by product, obtain Methyl Hydrogen Polysiloxane Fluid, again Methyl Hydrogen Polysiloxane Fluid is dropped in the reaction flask, and back flow reaction in polyoxyethylene mono allyl ether that will make in advance and the catalyzer input reaction flask, make the silicone antifoam agent product, the silicone antifoam agent consumption is 10-100000ppm.
The present invention compare with prior art have that technology is simple, cost is low, advantage, and this research high molecular polymerization developing direction both at home and abroad that links closely, market-oriented, fill up China's blank, satisfy market in urgent need, can meet the invested in plant manufacturing technique requirent, can produce environment-friendly type, the no three wastes, water-based, do not contain organic solvent, nontoxic, the new type hot-melt adhesive glue that do not have blast, no danger of combustion, be worthy of popularization.
