Abstract
The invention relates to a polyvinyl butyral (PVB) adhesive and a preparation process thereof. The PVB adhesive and the preparation process are mainly used in the production processes of tipping paper and aluminium-foil paper for cigarettes and outer wrapping paper for cigarette cases. The PVB adhesive is prepared from the following raw materials in parts by weight: PVB, ethanol, cyclopropane, rosin, alcohol soluble phenolic resins, octadecanol, dibutyl phthalate and talc. The invention has the following advantages and beneficial effects: the PVB adhesive has strong adhesion, can not only brighten the films but also further brighten the films during friction, is not easy to change color and has low cost; and the preparation process is simple and convenient to operate and easy to implement.
Description
Technical field
The present invention relates to a kind of tackiness agent, relate in particular to a kind of PVB tackiness agent and preparation technology thereof, be mainly used in the production of cigarette with yew paper, aluminium-foil paper and cigarette case overwrap.
Background technology
At present, along with the continuous development of cigarette technology and improving constantly of living standards of the people, cigarette has been proposed requirements at the higher level with material, wanted bright nondiscoloration as yew paper, color printing even three-dimensional seal should be easier on yew paper; The not shedding of aluminium-foil paper light; Decorate the external packing box burnishing.Satisfy above-mentioned requirements, PVB-6# glue must strong adhesion, the light of filming, not easy to change.And PVB-6# glue of the prior art far can not satisfy above-mentioned characteristic.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, through a large amount of research with constantly explore, provide a kind of PVB tackiness agent, solved PVB-6# glue poor adhesive force in the prior art, brightless, the allochroic problem of filming, and cost is lower.
Another object of the present invention is to provide a kind of preparation technology of the PVB of preparation tackiness agent, and it is simple to operate, easily implements.
Technical scheme of the present invention is as follows:
Count ratio by following raw materials in parts by weight and be prepared from polyvinyl butyral acetal: ethanol: cyclopropane: rosin: pure resite: stearyl alcohol: dibutyl phthalate: talcum powder=180-320: 90-210: 30-80: 4-9: 3-8: 2-6: 1-5: 10-45.
Count ratio by following raw materials in parts by weight and be prepared from polyvinyl butyral acetal: ethanol: cyclopropane: rosin: pure resite: stearyl alcohol: dibutyl phthalate: talcum powder=226: 135: 46: 5: 4: 3: 2: 22.
Described ethanol is 95% ethanolic soln.
Preparation technology of the present invention is as follows:
Stir: in reactor, at first add ethanolic soln by above-mentioned weight ratio, slowly add polyvinyl butyral acetal at normal temperatures, behind the stirring 60-90min, add cyclopropane and stir;
Dissolving: above-mentioned solution is warming up to 50-70 ℃, treats slowly to add at normal temperatures polyvinyl butyral acetal all after the dissolving, reduce temperature in the kettle to normal temperature;
Miscible: rosin and talcum powder by after the above-mentioned weight ratio adding pulverizing after stirring, add pure resite, stearyl alcohol and dibutyl phthalate and carry out miscible;
Filter: the solution after will be above-mentioned miscible filters, must finished product.
Advantage of the present invention and beneficial effect are as follows:
1, improved the sticking power of tackiness agent, its sticking power is strengthened;
2, not only can make the blast of filming, and can make film brighter in when friction;
3, not easy to change, cost is low, and easy and simple to handle, easily implements.
