Description
Technical field
The present invention relates to a kind of preparation method of thermal transfer paint for papers, belong to technical field of polymer materials.
Background technology
Thermal transfer is an emerging typography, incoming by foreign countries.Thermal transfer is also referred to as heat sublimation, is by portrait, wind
Any images such as scape are added using thermal transfer ink printed on heat-transferring printing paper, then by corresponding thermal transfer equipment in several minutes
Heat arrives certain temperature, is transferred in the materials such as porcelain cup, porcelain dish, porcelain plate, clothes, metal the image color on paper is true to nature
A kind of special process.Heat-transferring printing paper is the carrier of transferred image, and he is in bright gay color degree, the image fidelity after the transfer of image
It is most important.
Influence of the quality of thermal dye sublimation transfer printing paper to product printing quality plays direct effect.The ink of paper absorbs
Uniform type, the speed degree for absorbing ink determines the print quality of heat sublimation printing paper, and good print quality is to ensure production
The basis of product printing quality, excellent transfer performance, it is desirable to which thermal dye sublimation transfer printing paper has larger tightness, control dyestuff is heated to be risen
Will not be from the back side diffusion of page when magnificent.Meanwhile, thermal dye sublimation transfer printing paper will also have preferable page stability, otherwise be become by heat
Shape, causes the ghost image of image smudgy.However, the inferior quality of current heat-transferring printing paper body paper, is mainly shown as that body paper is needed
Carry out the coating of special coating, the absorbency of coating is bad, ink droplet infiltration rate is slow, and image has obvious heap ink when printing is finished
And color bleeding phenomenon.
In summary, a kind of coating of research invention, the coating ink absorption that it is formed is good, and ink absorption speed is existing soon
There is the most important thing that technical staff studies.
The content of the invention
The technical problems to be solved by the invention：Need to carry out the coating of special coating, the suction of coating for current body paper
Ink is bad, ink droplet infiltration rate slow, and there is provided a kind of heat for the problem of image has obvious heap ink and color bleeding phenomenon when printing is finished
Transfer the preparation method of paint for papers.
In order to solve the above technical problems, the present invention is using technical scheme as described below：
（1）Take guar gum, castor oil polyoxyethylene ether, ammonium hydrogen carbonate and aqueous solution of propylene glycol to be put into reactor, use nitrogen
Protection, reuses sodium hydroxide solution regulation pH to 8.5~9.0, adds sodium metasilicate, preheated at 35~40 DEG C；
（2）After preheating terminates, dibutyl tin laurate is added, 45~50 DEG C are warming up to, and ammonium chloride solution is added dropwise, it is quiet
Put, then heating, add monoxone, stirring reaction；
（3）After the completion of reaction, room temperature is cooled to, discharges, collects out material, and is distilled to going out material, distillation is collected surplus
Excess, is washed to distillation residue using ethanol solution, collects washings, washings is dried, collect dried object；
（4）Count by weight, take 50~60 parts of dried objects, 30~35 parts of water, 12~15 parts of n-hexanes, 10~15 parts of acryloyls
Amine, 7~10 parts of MethacryloyloxyethylTrimethyl Trimethyl Ammonium Chlorides and 1~2 part of ammonium persulfate, are put into reactor, use nitrogen
Protection, is reacted at 70~75 DEG C, and reactant mixture is collected in discharging, you can obtain thermal transfer paint for papers.
The step（1）Middle guar gum, castor oil polyoxyethylene ether, the mass ratio of ammonium hydrogen carbonate and propylene glycol solution are 4
~5:0.4~0.8:1:7~9.
The step（1）The addition of middle sodium metasilicate is the 20~25% of guar gum quality.
The step（2）The addition of middle dibutyl tin laurate is guar gum quality 0.6~0.9%, and ammonium chloride is molten
The dripping quantity of liquid is guar gum quality 30~35%, and chloroacetic addition is guar gum quality 30~35%.
The present invention is compared with other method, and advantageous effects are：
The present invention in the presence of catalyst dibutyltin dilaurylate, passes through chlorination using the guar gum of low viscosity as matrix
Ammonium and monoxone are modified to guar gum, are obtained the guar gum of anionic property, are made modified guar gum have high electric charge close
Degree, can rest on paper surface rather than penetrate into inside paper fibre, prevent ink from oozing using electrostatic repulsion
Enter in paper fibre, improve transferring rate, while in modifying process, using sodium metasilicate as raw material, forming Bio-sil, being modified
Guar gum is wrapped up, and improves space therein, and then adds the adsorption efficiency to ink, then with acrylamide, metering system
Acyloxyethyl trimethyl ammonium chloride is as raw material, and the space in silica gel and modified guar is polymerize, in increase space
Cations, further improve the adsorption capacity to ink, also increase the rate of drying of ink, are carried while adding n-hexane
Height volatilization efficiency, and the present invention is degradable from the guar gum in natural gum, it is environmentally safe.
Embodiment

Reference examples：The thermal transfer paint for papers of Dongguan City new material Co., Ltd production.
Example and the thermal transfer paint for papers of reference examples are applied in thermal transfer, and it tested, concrete application
And test as follows：
Concrete application is as follows：Example and the coating of reference examples are coated on heat-transferring printing paper using airblade coating mode（Zhejiang Jinchang
The production of speciality paper limited company）On, control quantification of 95g/m2, after end to be coated, it is dried, applied
There is the heat-transferring printing paper of coating.
Specific test is as follows：
（1）The absorbability of ink is determined：Using the dirty test method(s) of ink, excessive heat sublimation ink is coated on above-mentioned scribble
The heat-transferring printing paper surface of material, and kept for the regular hour, then unnecessary ink wiping is fallen with soft cloth, dirty area is determined respectively
Domain and the paper reflectivity of white space, the absorbability of ink is represented with K＆N values, and calculation formula is as follows：
R in formula∞For the reflectivity of sufficiently thick white space（%）；RFMean the reflectivity in the dirty region of ink.
（2）Drying time determines：Designed pattern is printed to using piezoelectric type digital-code printer and heat sublimation ink
On the above-mentioned heat-transferring printing paper for scribbling coating, its drying time is determined.
Specific testing result such as table 1.
Table 1
As shown in Table 1, the oil absorbency of the coating for the thermal transfer paint for papers formation that prepared by the present invention is good, when printing is finished
Image is less prone to heap ink and color bleeding phenomenon, while required drying time is short, shows ink penetration in the speed of coating, and
Guar gum is degradable, environmentally safe.
