Description
Technical field
The invention belongs to hot transfer technique field, more particularly, the present invention relates to a kind of thermal dye sublimation transfer printing and useCoating is starched and is used this coating slurry to carry out the method for thermal dye sublimation transfer printing.
Background technology
In recent years, decorate too single problem, people in order to solve the product surfaces such as glass, pottery, metalStart to apply hot transfer technique, adopt the method for direct transfer printing to carry out pattern decoration to the goods of above material,But because the product surface of above material is smooth, polarity is larger, the adhesive linkage of general transfer film cannotCombine closely with the surface of the goods of above material, therefore, after transfer printing, picture and text are very easy to come off, and decorate effectFruit is unsatisfactory. For this reason, ZL200710033041 discloses a kind of solid, so that printing figure message is close toThe product surface of above material.
Although this patent has solved the picture and text of the product surfaces such as glass after hot transfer printing, pottery, metal and has been very easy toThe problem coming off, but pattern texture after transfer printing is very not clear, color fastness is very not high, and glossiness is good not,Can not meet the requirement that people are more and more higher to transfer printing effect.
Traditional thermal dye sublimation transfer printing refers to by printing thermal dye sublimation transfer printing ink printing to paper, by printed figurePaper and the fabric of literary composition overlap heating, pressurization or reduce pressure, the dyestuff on paper just becomes gas phase state to distil to turnMove on on fabric.
In recent years, the application of thermal dye sublimation transfer printing is more and more extensive, at present, adopts thermal dye sublimation transfer printing method canChromatic image is transferred to textile, glass, porcelain cup, porcelain dish, porcelain plate, plank, slabstone, gold realisticallyOn goods in the materials such as genus, concrete operation method is: the picture and text such as portrait, landscape, word are used and are equipped withThe ink-jet printer of thermal dye sublimation transfer printing ink is printed on thermal dye sublimation transfer printing with in ink jet paper in mirror image mode, then warpOverheated transfer apparatus is heated to 200 DEG C of left and right, makes the hot transfer ink distillation on heat sublimation paper penetrate into stockCan. But the goods of the materials such as glass, porcelain cup, porcelain dish, porcelain plate, plank, slabstone, metal are at heat literBefore China's transfer printing, must, through coating processing, could realize thermal dye sublimation transfer printing. Therefore, the exploitation of coating extremelyClose important.
For example, but at present conventional thermal dye sublimation transfer printing is wideless by coating slurry applicability, only can be applicable to weavingProduct or only can be applicable to ceramic etc., and pattern texture after transfer printing is very not clear, and color fastness is not veryHeight, glossiness is good not, still can not meet the requirement that people are more and more higher to transfer printing effect completely.
Summary of the invention
One of object of the present invention is: for the deficiencies in the prior art, and provide a kind of thermal dye sublimation transfer printing to useCoating slurry, that this coating slurry has is applied widely, pattern texture after transfer printing is clear, and color fastness is high, glossDegree advantages of higher.
In order to achieve the above object, the present invention adopts following technical scheme:
Thermal dye sublimation transfer printing is starched by coating, by mass percentage, comprises following component:
Aforementioned each constituent mass percentage sum is 100%;
Wherein, described hydroxyl telechelic polyester is acrylic resin modified admittedly containing 60 ± 2%, acid number 3-5mgKOH/g; ShouldThe acrylic resin modified characteristic that combines mylar and acrylic resin of hydroxyl telechelic polyester, in reactionIn the characteristics such as activity, adherence, salt spray resistance, have very large modification, and have splendid adherence, pliability,Salt fog resistance and recoatability, it can be used for metal substrate, magnadure, glass and slabstone etc. that difficulty is adhered to;
Described methyl etherified Lauxite or butyl etherificate Lauxite contain 75 ± 2% admittedly, acid number < 1mgKOH/g;Methyl etherified Lauxite or butyl etherificate Lauxite good stability, have high solids content, high rigidity, heightGlossiness, high activity, quick-drying, rapid curing, low VOC and good compatibility;
Acrylic resin modified and the methyl etherified Lauxite of this esters of acrylic acid levelling agent and hydroxyl telechelic polyester orThe compatibility of butyl etherificate Lauxite is comparatively desirable, thereby can form new boundary layer at coating surface,Play the effect of levelling. And this esters of acrylic acid levelling agent also has the effect of froth breaking. Better in order to realizeLevelling effect, in the present invention, the number-average molecular weight of esters of acrylic acid levelling agent is controlled at 6000～20000Between, molecular weight distribution is narrow, and vitrification point is controlled at below-20 DEG C, and surface tension is controlled at 25～Below 26mN/m;
Described diluent is the mixture of butyl acetate and DAA, and the mass ratio of the two is (1～10): 1.The effect of diluent is to reduce the viscosity of resin so that further processing, above two kinds of diluents withThermosetting acrylic resin and amino resins all have good compatibility.
Described coating slurry also comprises that mass percent is 3～20% thermosetting epoxy resin, thermoset epoxy treeFat has splendid adherence, resistance to xanthochromia, hardness, and glossiness is high.
With respect to prior art, the present invention adopts acrylic resin modified, the methyl etherified urea aldehyde of hydroxyl telechelic polyesterResin or butyl etherificate Lauxite, esters of acrylic acid levelling agent and diluent (butyl acetate and DAAMixture) composition mixture starch by coating as thermal dye sublimation transfer printing, due to hydroxyl telechelic polyester modification thirdOlefin(e) acid resin, is coated with so the thermal dye sublimation transfer printing making is used the main absworption peak of light outside solar spectrum scopeLayer has excellent light resistance and anti-outdoor aging performance, has higher sun-proof grade. By coating of the present inventionSlurry be coated in stock surface, while then it being carried out to heated baking, hydroxyl telechelic polyester acrylic resin modified withThere is cross-linking reaction in methyl etherified Lauxite or butyl etherificate Lauxite (and thermosetting epoxy resin)Form network structure, the ink on thermal dye sublimation transfer printing ticker tape distils through gas phase, penetrates into cancellated paintRete, the imaging of sublimating after cooling, makes the pattern texture after transfer printing more clear, saturated, and color fastness is high, holdColour-fast for a long time, and glossiness is high.
In addition, there is splendid adherence and pliability because hydroxyl telechelic polyester is acrylic resin modified, therefore,When coating slurry of the present invention is coated in to stock surface, coating can be attached to the surface of stock securely,Thereby make the pattern after transfer printing can not come off, chap.
Thermal dye sublimation transfer printing of the present invention with coating slurry can be used for by pattern transfer to metal, glass, acrylic board,On the goods of the various material such as slabstone, plank, pottery and cotton, the scope of application is very extensive.
Experiment shows, coating slurry of the present invention is coated in after stock surface and oven dry, and its adhesive force can reachTo 0～1 grade, hardness reaches 2H～3H level, and glossiness reaches 86 °～92 °, and sun-proof grade reaches 5 grades.
