Abstract
The invention provides an environment-friendly laser aluminized transfer coating with high aluminum layer adhesion, which is characterized in that the coating comprises the following components by weight percentage: 4-25% of acrylic resin, 4-20% of cellulose ester, and 60-85% of organic solvent or aqueous solution of the organic solvent. The coating has the advantages that 1, the coating has the higher aluminum layer adhesion and the problem of dealuminzation in a subsequent stripping procedure is solved, and 2, the coating has better wear resistance, contamination resistance and brightness, and the brightness and wear resistance of obtained presswork are improved to some extent.
Description
Technical field
The present invention relates to the high aluminium lamination sticking power of a kind of environment-friendly type laser aluminized transfer coating.
Background technology
The environment-friendly laser aluminium plating transfer paper is as a kind of new packaging material, because it is in the absolute predominance of environmental protection, the aspect such as false proof, at present be widely used on the packing of the social fast-moving consumer goods such as tobacco, wine, makeup and tealeaves, and have wide market outlook.
But the performance of laser aluminized transfer coating has directly affected the laser molding performance of final packaging material, high temperature resistant, high humidity and post-production performance etc.The main transfer coatings that uses is the solvent-borne type transfer coatings in the market, and main solvent wherein is mainly the solvent of ester class, ketone and ethers.Because this kind solvent type transfer coatings has a large amount of solvent evaporates out when coating is dry, the existence of these solvents not only can endanger execute-in-place workman's physical and mental health to some extent, and can cause certain pollution to bad border; In addition, using in the transfer aluminum plated paper that this class transfer coatings production obtains still can more residual solvent, and this also will endanger human consumer's physical and mental health to some extent.For the consideration to human body and environmental hazard, State Tobacco Monopoly Bureau has formulated the limit index of volatile organic compounds in tobacco shred and the box packaging paper (VOCS), and all cigarette-brands must the strict composition of controlling objectionable impurities.
For reducing the use of poisonous organic solvent, the manufacturer of the transfer coatings of lot of domestic and international begins diversion to aqueous transfer coating, begin one after another to research and develop transfer coatings and the relevant raw materials of water-based, for example, put down in writing a kind of environmental-protection aqueous transfer coating in the Chinese patent application 201110183179.5, wherein adopt aqueous acrylic emulsion, aqueous polyurethane emulsion or modified aqueous polyurethane emulsion as film-forming resin, with ethanol, Virahol etc. as solubility promoter.Although also have at present other some research and reports about aqueous transfer coating, but owing to be subjected to the restriction of existing water-based base mateiral, aqueous transfer coating can't really be broken through the series of key techniques such as temperature tolerance, snappiness laser molding and brightness of transfer coatings at present all the time, so, aqueous transfer coating still fail at present to replace the solvent-borne type transfer coatings the position and by application in batches.So develop the emphasis that the work of the solvent-borne type transfer coatings of various modifications is still the work of present transfer coatings field.
Aluminizing of employed wrapped product shifted class coating in the market, no matter is in product performance, or on coating process defectives of various degrees all.The problems such as being mainly manifested in use when raw and auxiliary material slightly has when improper, and printed matter surface will occur that aluminium lamination be full of cracks, tack are poor, printing ink adheres to bad, the quick-fried look in cross cutting folding line place, the existence of this defective has restricted the development of transfer coatings industry greatly.Material only presents good sticking power, just can not occur the phenomenons such as anti-sticking, mill flower in following process, guarantee printed patterns complete.
Summary of the invention
The object of the invention is to overcome the defective that prior art exists, provide that a kind of aluminium lamination sticking power is good, the high laser aluminized transfer coating of the simple environment-friendly type of painting process.
In order to achieve the above object, technical scheme of the present invention provides the high aluminium lamination sticking power of a kind of environment-friendly type laser aluminized transfer coating, it is characterized in that, by acrylic resin 4%～25% by weight percentage, cellulose ester 4%～20% and organic solvent or its aqueous solution 60%～85% form.
Preferably, the second-order transition temperature of described acrylic resin is 45～80 ℃, and acid number is 3～8mgKOH/g.
Preferably, described cellulose ester is at least a in cellulose acetate ester, cellulose acetate propionate ester, cellulose acetate butyrate ester and the carboxymethyl cellulose acetate butyrate ester, and its second-order transition temperature is 120～160 ℃, and the mass content of hydroxyl is 1～8%.
Preferably, described organic solvent is at least a in ethyl acetate, n-propyl acetate, butylacetate, acetone, butanone, ethanol, butanols and the propylene glycol monomethyl ether.
The invention has the advantages that: have higher aluminium lamination sticking power, avoided the dealuminzation problem in follow-up stripping process, having solved aluminizes in the market shifts that class coating aluminium lamination easily chaps, tack is poor, printing ink adheres to bad, the quick-fried look in cross cutting folding line place, the problems such as anti-sticking, that mill is spent appear in following process, simultaneously biodegradable, the easy processing of this kind coating meets the requirement of environmental protection.
