Abstract
In order to stick paper label as polar material onto bottle of plastic as nonpolar material, the present invention uses polyetylene wax as nonpolar material, polyvinyl alcohol as polar material and emulsifier to prepare aqueous emulsion based on the adsorption theory of adhesive. Practice shows that the emulsion has great adhesion to plastic bottle and paper label, good initial adhesion property and high adhesion strength as well as high storage stability. Using water as solvent makes it non-toxic, smell-less and pollution-less. It has wide use range and may be used mechanically and manually.
Description
The invention belongs to the tackiness agent class.Be exactly specifically paper label is pasted tackiness agent on the Plastic Bottle.
Along with the develop rapidly of plastics industry, it is more and more that packing plastic bottle uses.All used plastic bottle packing as medical drugs, beverage, daily cosmetics, chemical reagent etc.The Plastic Bottle light weight, be difficult for broken, appearance is unique, long service life, reclaim easily, easy to use.Commercial goods labels on these packing plastic bottles, a kind of is to be directly printed onto on the Plastic Bottle, this mainly is various daily cosmetics; Another kind is a plastic label, mainly is heat-shrinkable film, is subjected to heat sensitive characteristic according to plastics film, meets thermal contraction, makes the plastics film label restraint Fu tightly on Plastic Bottle, as big beverage bottle such as Sprite, Gao Cheng, Coca-Cola, Jilibao; Also having a kind of is paper label, and paper label is pasted two types tackiness agent at present on the Plastic Bottle, and a kind of is solvent-borne type, and another kind is water-soluble.The former bonding strength is big, and adhesive effect is good, but because contain noxious solvent such as benzene,toluene,xylene, makes its application be subjected to certain restriction; The latter comprises the plant amylum class, polyvinyl acetate (PVA) (white glue with vinyl) class, polyvinyl alcohol and cellulose family, they are solvent with water, safety non-toxic, but they can only temporarily paste label paper on the Plastic Bottle, will come off voluntarily after the drying, sticking effect is very bad.Often coming off as the label on some chemical reagent bottle and the medical drugs bottle is exactly that this reason causes.At present, what the paper label on some Plastic Bottle used is acrylate pressure sensitive adhesive (being non-setting adhesive), and its bonding strength is big, and adhesive effect is very good, but cost is too high, is tens times of general aqueous binder; Its inconvenient operation, can only be by hand label is attached on the Plastic Bottle one by one, can not mechanized operation, so that its application is subjected to certain restriction.
In recent years, mostly the patent of China's this respect was paper compound (promptly answering film) tackiness agent.Be used for that the tackiness agent of paper label has only CN1040607A on the Plastic Bottle.The present invention is identical with its purposes, but that raw material differs greatly is very big, and principle is different, and technology is also different.
Based on above various reasons, special for this reason proposition the present invention is to solve the problem that present Plastic Bottle usually comes off with paper label.
This bright principle is that the material of Plastic Bottle mainly contains: polyester, high density polyethylene(HDPE), polypropylene, polycarbonate, polystyrene etc., and these materials mainly are non-polar materials, label paper then is a polar material.Adsorption theory and polarity theory according to similar mix principle and tackiness agent, the present invention selects the material of nonpolar polyethylene wax as bonding plastics for use, select the material of polar polyvinyl alcohol for use, as emulsifying agent, above-mentioned two kinds of materials are emulsified into emulsion with sodium stearate as adhesive labels paper.This emulsion all has good adhesive effect to various Plastic Bottles and paper label.
Aqueous glue for sticking paper label onto plastic bottle of the present invention mainly is applicable to paper label is pasted on the Plastic Bottle, also can paste other plastic tank to paper label, the plastics kettle, on plastics casing and various plastics and the Polywoven Bag, otherwise, also can stick on plastic label on the paper product.It is solvent with water, and nontoxic, no burn into does not have any smell, non-environmental-pollution; Its initial bonding strength is good, and bonding strength is big, and sticking is firm, difficult drop-off; Its excellent storage stability is placed and still can be continued after 2 years to use; It is cheap, and is easy to use, and applied range both can mechanically use, and can paste by hand again.
