Abstract
The present invention relates to an adhesive for sticking a paper label onto a plastic bottle, which is characterized in that the plastic bottle is mainly made from non-polar materials; the label paper is made from polar materials; an emulsifier is added to polyethylene wax as the non-polar material and polyvinyl alcohol as the polar material to carry out emulsification so as to form a water emulsion according to the absorption theory of the adhesive. Practice shows that the emulsion has favorable adhesiveness to the plastic bottle and the paper label. The present invention has the advantages of good initial adhesiveness and great adhesion strength, and the label can be firmly stuck and is not easy to fall off. The present invention uses water as a solvent, and thereby, the present invention has the advantages of no toxicity, no taste and no environment pollution. The present invention has good storage stability and can still be used after being stored for two years. The present invention also has the advantages of cheap price, convenient use and broad application, and can 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 packing plastic bottle as medical drugs, beverage, daily cosmetics, chemical reagent etc.Plastic Bottle light weight, difficult fragmentation, exotic shape, long service life, recovery, easy to use easily.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, and it is to be subjected to heat sensitive characteristic according to plastics film, meets thermal contraction, the plastics film label is strapped on the Plastic Bottle tightly, as beverage bottles such as Coca-Cola, Jilibao, Sprite, Gao Cheng; 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 type.The former bonding strength is big, and adhesive effect is good, but because contain organic 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 label on some Plastic Bottle used is acrylate pressure sensitive adhesive (being non-setting adhesive), and its bonding strength is big, and sticking 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 CN4040607A 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.
Principle of the present invention 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.According to the adsorption theory of similar mix principle and tackiness agent, the present invention selects the material of nonpolar polyethylene wax as bonding plastics for use, selects the material of polar polyvinyl alcohol as adhesive labels paper for use, uses sodium stearate as emulsifying agent.Above-mentioned two kinds of materials are emulsified into emulsion.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 be applicable to paper label is pasted on the Plastic Bottle, also can paste paper label on other plastics (as plastic tank, plastics kettle, plastics casing, Polywoven Bag), otherwise, also can paste 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, and difficult drop-off: its stability in storage is good, places and still can continue after 2 years to use; It is cheap, and is easy to use, and applied range both can use by machinery, can paste by hand again.
