Abstract
This is an adhesive, a water-soluble adhesive particularly suitable for sticking trademark posters to plastic products. It utilizes the different properties of natural resin and synthetic resin, and adopts modification treatment to properly control the ratio of water-soluble component and water-insoluble component, and utilizes the property of surfactant to retain emulsified state of solution. The water-soluble adhesive has low cost, no toxicity and harm, does not need to add other solvents when in use, does not dry and shrink and go moldy and go bad after being stored for a long time, has high stability after being bonded, is not easy to fall off at minus 20-45 ℃ or in a humid environment, has good finished product fluidity, is very suitable for mechanical coating, and can realize the desire that people need to directly paste exquisite trademark posters printed by common art paper on an automatic production line onto plastic products.
Description
The present invention relates to a kind of tackiness agent, this is a kind of water-soluble adhesive for labels of plastic bottles and manufacturing process thereof that is specially adapted to the trade mark poster is sticked on surface of plastic products.
Since plastics come out, how to use cheap tackiness agent in its surface and paste exquisite papery trade mark poster, be an extremely headachy difficult problem.General tackiness agent commonly used as starch paste, gelatine, hide glue or water-soluble synthetical glue, as Vinyl Acetate Copolymer, polyvinyl alcohol series tackiness agent, all is helpless.When initial, like the trade mark poster having been sticked on the plastics, and after treating that tackiness agent is done, the trade mark poster just splits away off from plastics voluntarily.Some solvent-borne type synthetical glue, though the trade mark poster can be sticked on the plastics, too high because of cost, need use the harmful solvent that maybe can damage frosting again, so be not widely used.The existing comparatively receptible method of people is the pressure sensitive adhesive (be commonly called as and be non-setting adhesive) of utilization oleic series.Yet its use cost is still very high, compare cost with general halftone paper printing product and want high about five times, and production unit more complicated, extremely inconvenient during use, can only be attached to one by one on the plastics with the trade mark poster that by hand back side is scribbled pressure sensitive adhesive during stickup, can't on automatic production line, use.Produce in enormous quantities for adapting to automatization, also useful directly printing word method of patterning on surface of plastic products can be regrettably, owing to be subjected to the restriction of plastics shape, this method is difficult to generally adopt; And this method can only the printing color dullness simple pattern, be difficult to reach and decorate exquisite purpose.
The objective of the invention is to provide a kind of with low cost, toxicological harmless, easy to use and reliable, the papery trade mark poster of fineness can be sticked on securely the water-soluble plastic bottle tackiness agent on the plastics.
Principle of the present invention, it is the different performance that utilizes natural resin and synthetic resins, they are carried out modification handles, with the sex change of water-fast composition part is water-soluble components, control the ratio of suitable water insoluble composition, make the bond properties of its maintenance, utilize the emulsification of tensio-active agent simultaneously and ooze suitable performance to keep the emulsified state of solution to plastics, increase is to the penetrating power of paper fiber, thereby very high stability is arranged after making it bonding.
This with modified natural resin, synthetic resins and tensio-active agent, add the water-soluble binder that plant amylum and water are made through the heating assembly, be not only applicable on plastics, paste the trade mark poster, and can on the surface of glass, bamboo wood, metal products etc., paste the trade mark poster securely.Employed raw material was the general chemical raw material of more easily buying on the market during it was produced, and price is more cheap; In production process and use, the nonhazardous gas material overflows, to environment and all pollution-free infringement of human body; With water is solvent, and long-term storage can drying shrinkage, can moldy metamorphism; Its finished product non-corrosiveness can directly use and not need to add in addition other solvent, but thin up in the use can not damage plastics; After bonding, very high stability is arranged, equal difficult drop-off in-20～45 ℃ and moist environment; And finished product is an aqueous emulsion, and is mobile fabulous, is adapted to very much mechanical application, and this hope that just can make people directly to paste on the plastics at the trade mark poster of the fineness of on the automatic production line common enamelled paper being printed becomes a reality.
Embodiment of the present invention are:
Described modified natural resin, promptly be through alkaline purification with sylvic acid and pimaric acid [C
19H
(27～33)COOH] be the rosin series resin of major ingredient.Manufacture craft is: earlier rosin series resin and alkali and an amount of water are placed in the reactor, here so-called " in right amount ", be meant that water has just soaked input raw material live for well, make it at the following heating edge stirring reaction of 80～120 ℃ of conditions, about 1-4 of time hour, reaction is to there not being free state alkali, add water phase surfactant mixture again, after stirring, reactor temperature is reduced to 50～80 ℃, add synthetic resins again and continue to stir 1-4 hour, add the plant amylum aqueous solution at last, to be mixedly promptly become finished product after evenly.
It is resin that synthetic resins adopts Vinyl Acetate Copolymer; Tensio-active agent adopts fatty alcohol-polyoxyethylene ether; Alkali can adopt caustic soda, soda ash etc.
Concrete composition of raw materials is (by weight):
Rosin series resin 100-150 part, plant amylum 10-50 part, alkali 4-8 part, Vinyl Acetate Copolymer are resin 10-40 part, fatty alcohol-polyoxyethylene ether 0-30 part, water 500-800 part.
Claims (2)
1, a kind of being particularly suitable for sticks on water-soluble adhesive for labels of plastic bottles on the plastics with the trade mark poster, it is characterized in that: it by through alkaline purification with sylvic acid and pimaric acid [C
19H (
27-33) COOH] for rosin series resin, the Vinyl Acetate Copolymer of major ingredient is that resin, fatty alcohol-polyoxyethylene ether, plant amylum and water assembly are made, each component (weight) is: 100～150 parts of rosin series resins, 10～50 parts of plant amylums, 4～8 parts in alkali, Vinyl Acetate Copolymer are 10～40 parts of resins, 0～30 part of fatty alcohol-polyoxyethylene ether, 500～800 parts in water.
2, a kind of manufacturing process of water-soluble adhesive for labels of plastic bottles, it is characterized in that: earlier rosin series resin and caustic soda or soda ash and an amount of water are placed in the reactor, following heating edge stir abouts of 80～120 ℃ of conditions 1～4 hour, reaction is to there not being free state alkali, add after the fatty alcohol-polyoxyethylene ether aqueous solution stirs again, reactor temperature is reduced to 50～80 ℃, adding Vinyl Acetate Copolymer again is that resin continues to stir 1～4 hour, add the plant amylum aqueous solution at last, mix.
