Description
Technical field
The present invention relates to adhesive area, particularly relate to a kind of Water-soluble wet-type paper-plastic lamination adhesive for paper-plastic lamination and preparation method thereof.
Background technology
Paper-plastic lamination tackiness agent (being called for short multiple film glue) is the key factor of paper-plastic lamination technique.At present, commercially available multiple film glue mainly contains oiliness and the large class of water-based (water-soluble) two.The multiple film glue of oiliness generally adopts inexpensive poisonous benzene,toluene,xylene and volatile gasoline, vinyl acetate makees solvent, this not only produces the health of operator and poisons, and also severe contamination is caused to environment, and it is inflammable, explosive, be not easy to work in storage and transport, therefore prospect of the application is pessimistic.And aqueous laminating adhesive take water as medium, use safety, pollution-free, cost is low, complete environmental protection, and therefore the multiple film glue of use replaces the multiple film glue of oiliness has been trend of the times in multiple film industry.Aqueous laminating adhesive mainly contains dry type composite film glue and multiple film glue two class of wet type.The main drawback of the multiple film glue of existing water-based wet type is: initial bonding strength is low, cohesive strength is little, affect colored ink color and luster, water resistance is not so good, have the deficiencies such as foaming or delamination.
Summary of the invention
The object of the invention is to for above-mentioned existing problems and deficiency; there is provided a kind of and there is fabulous coating performance; there is tasteless, nontoxic, full-bodied feature simultaneously; and can place for a long time after mounting film, the foaming that do not turn yellow, not burst, the ink that can play protection product newly gorgeous, prevent paper to be subject to moist environment-friendly water-soluble wet type paper-plastic lamination adhesive and preparation method thereof.
Technical scheme of the present invention is achieved in that
Water-soluble wet-type paper-plastic lamination adhesive of the present invention, is characterized in by weight percentage, is made up of following composition:
VAE resin emulsion 70-89,
As the dibutyl phthalate of softening agent or dioctyl phthalate (DOP) 10-25,
As thickening dispersion agent acrylate copolymer 0.5-2,
As permeate agent fatty alcohol-polyoxyethylene ether 0.01-0.1,
As defoamer glycerine polyethenoxy ether 0.02-0.2,
Wax 0-1,
Water or water and ammoniacal liquor 0-10.
The component proportion optimization scheme of above-mentioned Water-soluble wet-type paper-plastic lamination adhesive is:
VAE resin emulsion 80-85,
Dibutyl phthalate or dioctyl phthalate (DOP) 10-18,
Acrylate copolymer 0.5-1,
Fatty alcohol-polyoxyethylene ether 0.05-0.1,
Glycerine polyethenoxy ether 0.05-0.1,
Wax 0.2-1,
Water or water and ammoniacal liquor 0-7.
In the present invention, VAE resin emulsion generally selects Ethylene mass to be the VAE emulsion of 10-30%.The viscosity of VAE resin emulsion preferably can not lower than 500 mPa.s, otherwise can cause stripping strength low, and impact uses.Be not higher than 900 mPa.s, otherwise other auxiliary addition agent can be affected be difficult to add and affect its use properties yet.The preferred version of the viscosity of VAE resin emulsion is 600-700 mPa.s.
Above-mentioned dibutyl phthalate is called for short DBP, and dioctyl phthalate (DOP) is called for short DDP.Above-mentioned thickening dispersion agent acrylate copolymer, can be acrylate, vinylformic acid and methyl acrylate, ethyl propenoate or multi-component copolymer acrylate etc.Above-mentioned wax adopts polyethylene wax or whiteruss.The object adding wax has in the present invention been synergistic function, further to improve glossiness and the water tolerance of glued membrane.
The preparation method of Water-soluble wet-type paper-plastic lamination glue of the present invention, comprises the following steps:
The VAE resin emulsion taken by said ratio, softening agent, thickening dispersion agent, permeate agent and defoamer, wax are placed in reactor and stir, viscosity and the pH value of mixed solution is regulated with water or water and ammoniacal liquor, pH value controls as 6.0-8.0, at the temperature of 20-30 degree, stir discharging after 30-60 minute again, the mixture of gained is described Water-soluble wet-type paper-plastic lamination adhesive.The viscosity of described Water-soluble wet-type paper-plastic lamination adhesive is generally 800-1000mPa.s.Preferable ph is 6.5-7.0.
The present invention is owing to adopting with VAE resin emulsion as main raw material, also introduce the raw material such as softening agent and thickening dispersion agent simultaneously and make multiple abdomen glue, thus make use of VAE resin emulsion fully there is excellent in toughness, elasticity and there is certain rigidity, shock resistance is with transparent feature and make use of the feature that softening agent can improve multiple film glue physicals, both effectively increased the toughness of glued membrane and improve the shock-resistance of glued membrane, vibration resistance and lower temperature resistance, multiple film glue is made to have high viscosity, big area dust can be eliminated, non-foaming, unburstable feature, and again because the effect of thickening dispersion agent can make the denseness of glue improve, the unit of glue softens.And also add the permeate agent of the strengthened glue stripping strength of suitable proportioning due to the present invention and emulsion foam can be eliminated, suppress the raw material such as defoamer of emulsion foam regeneration, further ensure that the quality of multiple film glue.Because the present invention also adds wax in formula, further improve glossiness and the water tolerance of glued membrane.In addition multiple film glue of the present invention also can have tasteless, nontoxic water to regulate the concentration of glue as thinner by apparatus according to the requirement of user, therefore easy to use, environmental protection.Add and use this product without the need to heating, saved electric power resource.Multiple film glue of the present invention has tasteless, nontoxic, high viscosity, can eliminate the feature of big area dust; and can place for a long time after mounting film, the foaming that do not turn yellow, not burst; can play protection product ink newly gorgeous, prevent paper to be subject to humidity, belong to novel environment friendly product.Import and the multiple abdomen machinery of domestic various water-based can be widely used in, easy to clean, pollution-free.
