Abstract
The invention discloses a kind of paper printed matter and laminated nontoxic type paper plastic adhesives of plastics film of being used for, the parts by weight scope of each component of prescription of this tackiness agent is: butyl acrylate 95-115; Vinyl acetate 90-110; Vinylformic acid 20-40; Benzoyl peroxide 0.5-1.0; Industrial alcohol 150-1000; Ammonia is an amount of.Because this tackiness agent is only made solvent (no benzene) with industrial alcohol.Safety when so this tackiness agent uses, nontoxic, environmental pollution is very little, and with low cost, its stripping strength, drying property and luminance brightness are good.
Description
The present invention relates to the tackiness agent that a kind of paper printed matter and plastic film laminate adhesive are used.
In printing industry, in order to increase the aesthetic property of printed matter, wear resistance and light, bonding a kind of plastic film on printed matters such as the Front cover of book and periodical of being everlasting, picture album, packing box face.Require bonding firmly, do not come off, smooth, no bubble, do not have and beat, execute this technology of reality and be referred to as multiple film.Its film coating method generally is to use coating machine tackiness agent to be coated on equably on the face of plastic film, plastic film after will being coated with is then sent in 50 ℃-70 ℃ the hot drying tunnel and is made its drying, dilution composition in the tackiness agent is vapored away, roll the coated face of plastic film and printed matter rolled by the hot pressing of coating machine at last and be bonded together.Use Japanese patent application " when the tackiness agent that day special clear 56-26274 makes is used to execute real above-mentioned technological experiment, to find that the viscosity of its tackiness agent is very big.But its force of cohesion is relatively poor.Behind the multiple film, be easy to plastic film is stripped down from printed matter, and at normal temperatures can not be dry behind the glue-line process drying tunnel, the printed matter behind the multiple film is when rewinding or lamination placement, and its edge is sticking mutually to be joined.And this tackiness agent need be made solvent with benzene class (as benzene, dimethylbenzene, toluene), fully dissolved dilution.For tackiness agent is coated on the plastic film uniformly, must use a large amount of solvent cut (solvent accounts for the 60%-80% of binder wt), to increase the wetting property of tackiness agent, advection is so that coating.But this benzene kind solvent toxicity is bigger, and when the hot drying tunnel of several meters long of processes, most of volatilization causes severe contamination to environment in air, bigger to operator's physical impairment.
The objective of the invention is to provide a kind of and make diluting solvent with industrial alcohol (nontoxic), and it is easily dry, and the tackiness agent with very strong stripping strength, it is characterized in that forming the parts by weight of each group of prescription of this tackiness agent and the parts by weight scope of industrial alcohol solvent and be:
Butyl acrylate 95-115
Vinyl acetate 90-110
Vinylformic acid 20-40
Benzoyl peroxide 0.5-1.0
Industrial alcohol 150-1000
Ammonia is an amount of
Each the composition weight umber of tackiness agent optimum formula of the present invention and the parts by weight of industrial alcohol solvent are:
Butyl acrylate 112.5
Vinyl acetate 108
Vinylformic acid 29.5
Benzoyl peroxide 0.8
Industrial alcohol 750
Ammonia is an amount of
Above-mentioned prescription forms tackiness agent of the present invention, compare with the clear 56-26274 patent of day spy, it is very big and at room temperature can not exsiccant vinylformic acid a-ethylhexyl (Tg=-70 ℃) to have left out viscosity in its prescription, increase the content of d ritalinic acid vinyl acetate (Tg=32 ℃), the hardness of the tackiness agent of formation is improved, thereby its force of cohesion is strengthened, at room temperature the glued membrane drying, and have thermoplasticity, improved the stripping strength of tackiness agent to a great extent.Left out methyl propenoic acid glycidyl ether again, and improved acrylic acid content, the acid number of tackiness agent is improved.But it is water-soluble in the ammonification on manufacturing process like this with acquisition.Because in industrial alcohol, contain the moisture of 5%-7%, like this, make tackiness agent in industrial alcohol, be able to sufficient dissolving.Quality problems such as (it is to be noted that it is impracticable that whole waters are cooked solvent, because the rate of volatilization of water is too low, plastic film coating be after during overheated drying tunnel, can't dry water) making again the very easy generation bubble of printed matter after thin or beat.The overall solubility parameter of tackiness agent of the present invention is close with the alcoholic acid solubility parameter, can be dissolved in fully in the industrial alcohol solvent through experiment.
Compare with Japanese " day special clear 56-26274 " patent, paper plastic adhesives of the present invention has following feature: can be dissolved in the industrial alcohol, drying property is good under the normal temperature, and has thermoplasticity.Because the raising of hardness, thereby strengthen the stripping strength of tackiness agent greatly, made it to be applicable to very much the technological process of paper-plastic lamination.When doing the separability test behind the multiple film of paper printed matter, can get off the ink band on the printed matter or, and find no foaming, phenomenon such as beat from the fibrous inside destruction of papery product.
The embodiment of a preparation paper plastic adhesives of the present invention is described below
Embodiment
1. in reactor, add the 200kg industrial alcohol, be warming up to 70 ℃ after, constant temperature.
2. butyl acrylate 112.5kg, vinyl acetate 108kg vinylformic acid 29.5kg benzoyl peroxide 0.8kg are mixed in mixing kettle dissolve each other after, get in the disposable input reactor of its amount of 1/3, open and stir, temperature is controlled at 70 ℃-75 ℃, reacts 3 hours.
3. when stirring, drip the residue 2/3 monomeric mixing thing that dissolves each other, evenly dropwise in 4 hours, temperature is controlled at 70 ℃-75 ℃.
4. after dropwising, continued stirring reaction 12 hours, temperature is controlled at 70 ℃-75 ℃, obtains colourless transparent liquid.Be cooled to 45 ℃ then, when stirring, fed ammonia about 15 minutes from the glue bottom.
5. add remaining 550kg industrial alcohol, continue stirring and can take the dish out of the pot in 30 minutes.
