Description
Technical Field
The invention relates to the field of thermal sublimation transfer printing paper processing technologies, in particular to a high-transfer-rate thermal sublimation transfer printing paper processing technology with an infiltration inhibiting effect.
Background
Most of the common thermal sublimation coatings on the market contain a large amount of porous materials, and ink is absorbed through the porous structures of the materials and the capillary action of the microporous structures formed among the materials, so that the ink is fixed in the coatings. And when the heating rendition, porous structure easily produces the secondary to the dye molecule of coating sublimation and adsorbs, leads to the condition that the sublimation is hindered, therefore produces negative effects to the transfer rate. Meanwhile, due to the phenomenon of reverse sublimation of dye molecules in ink infiltration and transfer during printing, the transfer rate of the transfer printing paper at present has a larger lifting space.
Disclosure of Invention
The invention mainly solves the technical problem of providing a high-transfer-rate thermal sublimation transfer paper processing technology with a permeation inhibition effect, wherein N- (4, 6-diamino-1, 3, 5-triazine-2-yl) ethanesulfonamide with a new micromolecule structure is introduced as a filler material, a first coating with the thickness of 1-5 g/square meter is applied on the front surface of base paper, after the base paper is completely dried by an oven, a second coating with the thickness of 1-7 g/square meter is coated on the first coating, after the base paper is dried by a plurality of ovens, the base paper enters a drying cylinder, and finally the base paper is rolled to obtain the finished transfer paper. The obtained product has high transfer rate and permeability resistance.
In order to solve the technical problems, the invention adopts a technical scheme that: the processing technology of the high-transfer-rate thermal sublimation transfer printing paper with the permeation inhibition effect comprises the following steps:

All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Before the process of the invention is implemented, the inventors of the present application have conducted various investigations to find out that: most of the common thermal sublimation coatings on the market at present contain a large amount of porous materials, and ink is absorbed through the porous structures of the materials and the capillary action of the microporous structures formed among the materials, so that the ink is fixed in the coatings. And when the heating rendition, porous structure easily produces the secondary to the dye molecule of coating sublimation and adsorbs, leads to the condition that the sublimation is hindered, therefore produces negative effects to the transfer rate.
In order to solve the technical problems of the above investigation results, the embodiment of the present invention introduces a processing technology of a high transfer rate thermal sublimation transfer paper with a permeation inhibition effect, including the following steps:
the method comprises the following steps: preparing a first coating glue solution: preparing 24 parts by weight of polyvinyl alcohol, 33 parts by weight of carboxyl butyl benzene latex, 41 parts by weight of carboxymethyl cellulose and 8 parts by weight of film-forming additive, weighing and mixing to prepare glue solution with solid content of about 20%, and stirring at room temperature for 60min for later use;
step two: preparing a second coating glue solution: preparing 36 parts by weight of film forming agent and 3 parts by weight of dispersing agent, weighing and mixing, adding water at room temperature, and stirring uniformly. Preparing 58 parts by weight of (N- (4, 6-diamino-1, 3, 5-triazine-2-yl) ethanesulfonamide, 3 parts by weight of talcum powder, 3 parts by weight of bamboo wood powder and 8 parts by weight of magnesium oxide, weighing and mixing, finishing feeding in three times under a stirring state to prepare glue solution with the solid content of about 23%, and continuously stirring for 60min at room temperature after feeding;
wherein, the film-forming additive in the step one is selected from 6 parts of glycol and 6 parts of dodecyl alcohol ester; the film forming agent in the second step is selected from 6 parts of sodium carboxymethylcellulose, 6 parts of polyethyl acrylate, 6 parts of guar gum, 6 parts of polyvinyl acetate emulsion, 6 parts of rosin emulsion and 6 parts of carboxyl butyl benzene latex; the dispersant in the second step is selected from 3 parts of Guerban;
step three: applying the first coating glue solution prepared in the first step on the surface of a base paper base with the thickness of 50 grams per square meter at the speed of 120m/min, controlling the glue application amount to be 3 grams per square meter, and then sending the base paper base into 3 drying ovens for drying treatment, wherein the temperature of the drying ovens is set to be 80 oC；
Step four: applying the second coating glue solution prepared in the second step on the surface of the product obtained in the third step, controlling the glue application amount to be 6 g/square meter, and then sending the product into 5 drying ovens for drying treatment, wherein the temperature of the drying ovens is set to be 80oC；
Step five: feeding into 1 drying cylinder for complete drying treatment, wherein the temperature of the drying cylinder is set to 100oAnd C, rolling to obtain finished paper.
Wherein, the preparation process of the (N- (4, 6-diamino-1, 3, 5-triazine-2-yl) ethanesulfonamide comprises the following two steps:
step 1: ethylsulfonic acid (2 g, 1.0 equiv.) was added to 20mL of dichloromethane, and 2 drops of N, N-dimethylformamide were added dropwise. Stirring for 10 min, cooling to 0 deg.C, and slowly adding thionyl chloride SOCl dropwise2(2.3 g, 1.05 equiv.) and the reaction stirred for 1 hour. After the reaction is finished, the solvent and excessive thionyl chloride SOCl are removed by rotary evaporation2To obtain ethylsulfonyl chloride for later use.
Step 2: 1,3, 5-triazine-2, 4, 6-triamine (2.29 g, 1 equiv.) was added to 25 mL of 1-methylimidazole, the temperature was reduced to 0 ℃ and ethylsulfonyl chloride (2.34 g, 1 equiv.) was added dropwise with stirring. After the dropwise addition, the reaction solution is warmed to room temperature for 2 hours. After completion of the reaction, the reaction mixture was washed with saturated aqueous sodium bicarbonate, extracted with ethyl acetate, and the organic layer was taken out and spin-dried to obtain the objective compound N- (4, 6-diamino-1, 3, 5-triazin-2-yl) ethanesulfonamide (1.5 g, 37.87%).
The compound (N- (4, 6-diamino-1, 3, 5-triazin-2-yl) ethanesulfonamide) thus obtained has the structural formula
Therefore, the second coating glue solution can be used for replacing a porous material in a traditional coating by selecting a small-molecular material N- (4, 6-diamino-1, 3, 5-triazine-2-yl) ethanesulfonamide, so that the technical problem can be solved. Namely, the N- (4, 6-diamino-1, 3, 5-triazine-2-yl) ethanesulfonamide is a novel efficient thermal sublimation functional material. The material and dye molecules can quickly generate interaction, so that the dye molecules are fixed, the dye molecule infiltration is slowed down, and the thermal sublimation performance of the coating material can be greatly improved. The material has a simple structure, and has efficient release property to dye molecules at high temperature, so that the thermal sublimation transfer rate of the coating material is effectively improved. On the other hand, the first coating glue solution is a high-molecular coating with high density, and the coating can effectively prevent ink from seeping downwards and effectively reduce the number of dye molecules seeping into the paper fiber layer. Meanwhile, in the transfer printing process, the coating can play a certain role in blocking dye molecules which are sublimated reversely, and can promote more dye molecules to be effectively sublimated.
Based on the above principle, the inventors of the present application have taken further performance test experiments to demonstrate the above view:
experiment one, permeability resistance test:
transfer paper produced by coating only the second coating layer on the same base paper is used as a reference. Two kinds of transfer paper at the temperature of 25 deg.coC, cyan (C), magenta (M), yellow (Y), and black (K) were printed in an ink ejection amount of 400 under an indoor environment with a humidity of 55%. 80oAnd C, drying for 2 minutes. The method comprises measuring the color difference of front and back sides of transfer paper with NR10QC type color difference meter of 3nh manufacturer, and determining the penetration property of the paper with formula = CInverse direction/CIs justThe smaller the size, the better the permeability resistance of the paper. The data of permeability of the thermal sublimation transfer paper of the present invention versus the transfer paper produced by applying only the second coating layer are shown in fig. 1. Data show that the permeation effect of each color is remarkably reduced by adding the first coating isolation layer, which shows that the first coating isolation layer can effectively reduce the ink infiltration. Selecting a polyester fiber fabric as a printing stock, and carrying out hot pressing for 30s at 220 ℃ for transfer printing. Measuring the color difference of the transfer paper before and after transfer by using a color difference meter and obtaining the formula etac1=（C0-C1）/C0The four color transfer rates were calculated and the data pairs are shown in fig. 2. Test results show that after the first coating isolation layer is added to the transfer printing paper, the transfer rates of all colors are obviously improved to different degrees. The reason is that the added isolation layer can effectively reduce the situation that the ink permeates into the paper fiber layer to be fixed, and simultaneously provides a certain blocking effect for the reverse sublimation situation in the transfer printing process.
Experiment two, transfer rate test:
selecting inorganic porous filler such as silicon dioxide to substitute N- (4, 6-diamino-1, 3, 5-triazine-2-yl) ethanesulfonamide in the formula to prepare a coating material as a reference substance, coating the coating material on the same base paper, and producing the thermal sublimation transfer paper at the temperature of 25 DEG CoC, under the indoor environment with the humidity of 55%, selecting the ink jet amount of 400 to print cyan (C) and cyan (C) respectively,Magenta (M), yellow (Y), black (K). 80oDrying for 2 minutes under the condition C, selecting a polyester fiber fabric as a printing stock, and drying at 220 DEGoAnd C, hot pressing for 30s for transfer printing. The color difference of the transfer paper before and after transfer was measured using a model NR10QC color difference meter from a 3nh manufacturer and was calculated according to the formula etac1=（C0-C1）/C0The four color transfer rates were calculated and the data pairs are shown in fig. 3. The test results show that the transfer rates of various colors of the coating using the novel organic small molecule N- (4, 6-diamino-1, 3, 5-triazine-2-yl) ethanesulfonamide are improved to different degrees compared with the transfer rates of various colors of the coating using the inorganic porous filler.
