Description
The present invention relates to the adhesive techniques field, specifically special glue for lamination of aluminium foil.
, in the modern life, more and more be widely used with the goods of aluminium foil packing.And the performance issue that is used for the caking agent of aluminium foil also more and more is subject to people's attention.For example, the existing aluminium foil glue that is used for cigarette in packet mainly contains: 1) polyvinyl alcohol formaldehyde, and formaldehyde contains moderate toxicity, and carcinogenesis is arranged; 2) VAE emulsion (being multi-copolymerization emulsion), this external introduction of technology system, its use cost height, equipment is easy cleaning not, and uses this type of glue to need external specific equipment, the complex process introduced; 3) common Vinyl Acetate Copolymer (being white glue with vinyl) gather together to use, and its glued membrane is soft excessively, and creep properties is big, and use temperature is very low, does not have an ability of anti-deformation.
Japan's publication 57167363 (open day October 15 nineteen eighty-two) is a tackiness agent with polyvinyl acetate emulsion; its emulsifying agent is Walocel MT 20.000PV, added the softening agent dibutylester; polyvinyl alcohol with degree of hydrolysis 88% is a protective colloid, and consumption is about 7% of a monomer consumption.Its polyvinyl alcohol consumption still is the conventional formulation consumption; After adding the dibutylester softening agent, cause glued membrane soft excessively, creep properties is big; Walocel MT 20.000PV wherein is difficult for obtaining, and component is complicated.Be tackiness agent also in the disclosed article of " fine chemistry industry " 93 years 4 phases " development of the senior Adhisive for Aluminium Foil Paper of CUA-001 " with polyvinyl acetate emulsion; adopt compound emulsifying agent, composite modifier (the polyvinyl alcohol protective colloid is added the oxy-compound modification); add the softening agent dibutylester, its component has more complicacy.More than two prescriptions all fail the stiffness and the ability of anti-deformation of fine consideration glued membrane.
It is simple to the purpose of this invention is to provide a kind of component, and production method is easy, and cost is low, and can improve thermotolerance and glued membrane hardness, strengthens creep resistance, enlarges the special glue for lamination of aluminium foil of Applicable temperature scope.
The present invention is achieved in that with polyvinyl acetate emulsion be tackiness agent; with OP-10 is emulsifying agent; do not add any plasticizer, adopting the polyvinyl alcohol of super quantity scope is protective colloid and properties-correcting agent, and increases the adhesion curing difficult problem of wetting Agent for Printing Inks solution tackiness agent to equipment unit.
Concrete prescription is: by polyvinyl alcohol 5-8 part, and vinyl acetate between to for plastic 6-14 part, alcohols wetting Agent for Printing Inks 1-2 part, 0.1 part of Ammonium Persulfate 98.5 or Potassium Persulphate, 0.16 part of OP emulsifying agent, sodium bicarbonate is an amount of, and distilled water 40-80 part is formed basic recipe.
Wherein the alcohols wetting Agent for Printing Inks can be used multicomponent alcoholics compounds such as glycerol, propylene glycol, butyleneglycol, b propanol.
In basic recipe, also can add the VAE emulsion that accounts for total amount 15-40%.Applicable to 100-400 rice/minute various import high speed aluminium foil equipment complex.
In basic recipe, also can add food grade bubble enemy as defoamer.
The preparation method of special adhesive of the present invention and the production technique of polyvinyl acetate emulsion are basic identical.
The present invention is described in further detail below in conjunction with embodiment.
Embodiment 1, with 6.5 parts of polyvinyl alcohol, 8.5 parts of vinyl acetate between to for plastics, 0.1 part of Ammonium Persulfate 98.5,0.16 part of OP-10 emulsifying agent, sodium bicarbonate is an amount of, 1 part of alcohols wetting Agent for Printing Inks glycerol, 0.1 part of food grade bubble enemy, 60 parts of compositing formulas of distilled water can be by the production technique preparation of polyvinyl acetate emulsion.
Embodiment 2, with 7.5 parts of polyvinyl alcohol, 7.5 parts of vinyl acetate between to for plastics, 0.1 part of Potassium Persulphate, 0.16 part of OP-10 emulsifying agent, sodium bicarbonate is an amount of, 2 parts of alcohols wetting Agent for Printing Inks propylene glycol, 70 parts of distilled water add the VAE emulsion compositing formula of above-mentioned total amount 15% again, can be by the production technique preparation of polyvinyl acetate emulsion.Import equipment applicable to 100-300 rice/minute speed.
Special glue for lamination of aluminium foil of the present invention does not have following technical characteristic simultaneously except having preferably adhesive property:
1, vast scale uses polyvinyl alcohol, does not add plasticizer, makes the glued membrane after the curing that preferably hardness and anti-be arranged Creep properties strengthens the ability of anti-deformation that has improved the compound dedicated paper of aluminium foil greatly, and the aluminum foil composite paper of producing has Preferably stiffness and flatness, knuckle performance good (being that cigarette package folded edges angle gauge is then neat).
2, the glued membrane after solidifying has preferably heat resistance, has avoided that aluminium appears in the electrical heating position in the cigarette packer Paper tinsel bubbles even separates with paper. Also can avoid because environment temperature causes glued membrane to soften aluminum foil composite paper being rolled up easily Bent distortion.
3, the glued membrane after the curing has relatively poor resistance to water. Like this for substandard products and waste product aluminum foil composite paper can with Paper and aluminium foil are separated, and process respectively.
4, adding NMF makes special glue for lamination of aluminium foil that long normal temperature under shed digestion time be arranged. Namely at normal temperature The drying of lower adhesive, to solidify the required time longer, can not drying solidify to guarantee the glue on the smoothing roller. Because: 1. have one deck glue on the smoothing roller, the part that can be with aluminium foil be coated onto glue during by application roll is given Give and filling; 2. can be because not forming the planarization of uneven destruction aluminium foil surface behind the glue dry solidification on the smoothing roller.
5, adding NMF makes special glue for lamination of aluminium foil machinery equipment after use be easy to clean. With common gluing The agent meeting makes the many positions of equipment speckle with colloidal condensate, has a strong impact on the quality of production and be difficult to remove, and have to use Blade is scraped, sand paper is beaten, even scalds with boiling water, not only hinders very much equipment, and also difficulty accomplishes to remove fully totally, uses Behind the present invention, but only need with wet towel gently easily with regard to scrub, because could drying become after the polymer dehydration Film, and the hygroscopicity that glycerine has has blocked the formation of glued membrane and has solidified drying. And the glue after solidifying drying Exist in the film and have hydrophily and hygroscopic polyvinyl alcohol and glycerine.
6, the adding defoamer has successfully solved in the use of aluminium foil glue and has asked because of the foam of application roll rotation stirring generation (when revolving rubber roll and being stained with foam, the aluminium foil that is passed through can not be executed gluing at corresponding site to topic; Meeting that foam is many in addition Flow on the paper below the lacquer disk(-sc) and cause paper break).
Special glue for lamination of aluminium foil of the present invention is compared with prior art reaching product performance and is guaranteeing under the product quality premise, has accomplished to obtain raw material and the simplest production technique and equipment and make production with minimum, the most cheap, the easiest.And component is simple, and cost is low, can adapt to different type of machines and satisfy the requirement of apparatus processing speed up to 400 meters/minute.
