Abstract
The invention relates to the chemical product field, in particular to a method for producing thermal transfer hot-stamping adhesive. Based on the weight ratio, the raw material comprises 10-30 portions of acrylic resin, 25-40 portions of additive resin, 30-60 portions of hot-melt pressure sensitive adhesive and the residual is solvent; the solvent is firstly put into a reaction kettle, the additive resin is put into the reaction kettle in one time while stirring; the stirring process is 1-2 hours; the hot-melt pressure sensitive adhesive and the acrylic resin are mixed evenly and then put into the reaction kettle; when all the solids are melted and mixed evenly, the stirring process stops; and then the reaction kettle is stirred slowly for 0.5 hour; the mixture in the kettle is cooled, weighed and packaged. The thermal transfer hot-stamping adhesive has advantages of good adhesive force towards the preprocessed and unprocessed paper and various complex surfaces, wide application range, adjusting the adhesive force and the definition in large range easily according to different hot-stamped materials, clear details and non-splashing; the temperature range for the application of the adhesive is wide and is uneasy to be layered after long term storage.
Description
Technical field
The present invention relates to the organic high molecular compound field, a kind of specifically heat that is used for electrochemical aluminium shifts hot stamping glue and preparation method thereof.
Background technology
Blanching seal technology is meant utilizes special-purpose metal printing plate through heating, pressing mode electrochemical aluminum foil to be transferred to the printable fabric surface.This technology can be carried out three-dimensional thermoprint, and the picture and text that thermoprint is processed into have tangible three-dimensional level, forms anaglyph at printed matter surface, and produces the intensive visual impact, is widely used in high-grade printing packaging fields such as tobacco and wine.Have plurality of advantages just because of blanching seal technology, received users and human consumer's favor.But the performance of electrochemical aluminum foil has restricted the development of this technology, and the performance that therefore improves electrochemical aluminum foil is imperative.Yet one of them principal element that influences alumite thermoprinting foil performance and quality is that heat shifts hot stamping glue.
Electrochemical aluminum foil is to be basement membrane with the polyester film; Be coated with the novel material that has the coated coating of different chemical character with various; Concrete coating is: the first layer is a carrier thin film, and the second layer is a release layer, and the 3rd layer is color layers; The 4th layer is the vapor deposition layer, and layer 5 is an adhesive layer: make orange cold foil and product at high temperature form the key coat of sticking power.Huge to this kind electrochemical aluminum foil demand both at home and abroad at present; For abroad, the tackiness agent development trend of electrochemical aluminum foil is more single-minded, but price is higher; And that the development of the tackiness agent of domestic electrochemical aluminum foil is partial to is universal, and cost is lower.But, therefore, restricted the development of electrochemical aluminum paint industry greatly because stability, solidified nature, the thermotolerance of raw materials such as the employed parting agent of domestic existing electrochemical aluminium product, tinting material, sticker are all not ideal enough.Bonding coat particularly; Homemade adhesive layer exist thermoprint firkin, scumming, upward scald property bad, can not the thermoprint plastic sheet as filing arrangement, thermoprint sticking power is undesirable and the not high shortcoming of glossiness; Product performance are not as good as imported product, so this market is captured by external product basically.But the adhesive layer price of import is higher, therefore, presses for a kind of high performance gold stamping glue of development and comes substituting import one glue.Patent CN 1944558A is that several kinds of resins mix in solvent, and this patent making method ratio is easier to, and the adhesive layer of gained is used relatively good on certain base material, but the scope of application is narrower.
To above-mentioned situation, utilize hot-fusible pressure-sensitive adhesive and acrylate pressure sensitive adhesive advantage separately, the two is combined; Again carry out molecular designing, and the method for chemosynthesis, prepare heat and shift the hot stamping glue product; Like this, can help the raising of adhesive layer use range and other performances.
Summary of the invention
Technical problem to be solved by this invention is in order to overcome the deficiency of above-mentioned prior art, to provide a kind of heat that is used for electrochemical aluminium to shift hot stamping glue and preparation method thereof.
The technical scheme that the present invention solves the problems of the technologies described above employing is: a kind of heat that is used for electrochemical aluminium shifts hot stamping glue; It is characterized in that; Raw material is formed by weight percentage, comprises vinyl resin 10～30, additive resin 25～40, hot-fusible pressure-sensitive adhesive 30～60, and surplus is a solvent.
A kind of heat of producing electrochemical aluminium shifts the method for hot stamping glue, may further comprise the steps:
Step 1: vinyl resin synthetic
Propenoate and ETHYLE ACETATE are stirred in reaction flask, and logical nitrogen when being heated to 70 ℃, is incubated 2 hours, and then adds 1.5% Lucidol toluene solution, at insulation under this temperature about 3 hours, cooling discharge;
Step 2: hot-fusible pressure-sensitive adhesive synthetic
Vinylbenzene, propenoate and initiator Diisopropyl azodicarboxylate are added in the reaction flask by a certain percentage, be heated to 145 ℃, be incubated 1 hour, under this temperature, reacted discharging while hot 2 hours;
Step 3: batch mixing
By weight percentage, raw material comprises vinyl resin 10～30, additive resin 25～40, hot-fusible pressure-sensitive adhesive 30～60, and surplus is a solvent;
(1) earlier solvent is dropped in the reaction kettle, stir and additive resin is once dropped in the reaction kettle, stirred 1～2 hour;
(2) hot-fusible pressure-sensitive adhesive and the vinyl resin after will mixing slowly drops in the previous reaction still;
(3) after all solids dissolving and mixing, stop to stir;
(4) slowly stirred 0.5 hour cooling, weighing and bagging again.
The present invention also can realize through following measure:
Described solvent is one or more in butanone, toluene, ETHYLE ACETATE, the pimelinketone.
Described additive resin is a kind of in terpene phenolic resin, staybelite resin, petroleum resin, the α-Pai Xishuzhi.
Described propenoate is one or more in Isooctyl acrylate monomer, Bing Xisuandingzhi, vinyl-acetic ester, TEB 3K, the ethyl propenoate.
Initiator can also be the Lucidol toluene solution.
The invention has the beneficial effects as follows: this tackiness agent all has outstanding bonding force for pre-treatment and untreated paper and various compound surface; The scope of application is extensive, to different by the thermoprint base material, than the bonding force and the sharpness that are easier to reconcile significantly tackiness agent; Details is clear, no firkin; The wider range that this tackiness agent uses, the long-time placement is difficult for layering.
