Abstract
The invention provides a method for preparing polyurethane hot melting transfer print glue, which relates to transfer print glue and comprises the following steps of: loading polydiethylene butanediol adipate into a container; installing a stirring rod and a condensing pipe after the pressure reduction dewatering; then, placing the container into a water bath pot; adding diphenylmethane-4, 4' diisocyanate and catalysts of di-n-butyltin dilaurate after the polydiethylene butanediol adipate is cooled to the room temperature; carrying out water bath after the stirring; raising the temperature for taking reaction; then, adding small molecular chain expanding agents for continuing the reaction to obtain polyurethane hot melt adhesive solution; regulating the viscosity and the solid content of the prepared polyurethane hot melt adhesive solution; and coating the polyurethane hot melt adhesive solution onto an ink layer of a hot transfer print film. The ink layer becomes the heat transfer print glue film firmly printed onto various materials such as metal, glass, ceramics, plastics, fabrics and the like in a transfer print way after the solvents are volatilized. A good invasive performance with the ink layer of the hot transfer print film is realized, in addition, a good bonding performance with materials such as metal, glass, ceramics, various plastics, fabrics and the like is also realized, the ink layer can be firmly glued onto a printed material, and the polyurethane hot melting transfer print glue belongs the hot melting transfer print glue with wide purposes.
Description
Technical field
The present invention relates to a kind of transfer printing glue, especially relate to a kind of preparation method of polyurethane-hot melt transfer printing glue.
Background technology
Hot transfer technique be earlier with the plastic ink wire mark on a kind of dedicated transfer paper that can peel off, by heat transfer machine the picture and text on the paper are transferred on the daily necessities then.Because therefore advantages such as it has that printing effect is good, strong, durable and lovely luster have been widely used on the label printing of daily necessities.Hot transfer printing adhesive film is meant the picture and text that have sizing agent, under the acting in conjunction of heat and pressure, breaks away from carrier thin film with release layer, and firmly transfer printing is in the specific function print film on stock surface.Hot transfer printing adhesive film generally has four-layer structure, is respectively PET thin-film carrier, release layer, ink lay and adhesive-layer, and wherein the fundamental property of adhesive-layer is with the substrate article surface higher bonding force to be arranged, and guarantees that ink lay and matrix surface are in conjunction with firm.
Thermosol is often referred to and at room temperature is solid-state, and it is liquid that heating and melting becomes, and behind coating, the wetting adherend, through pressing, cooling, in seconds finishes cementitious sizing agent.Thermosol is a material of main part with the thermoplastic resin all, is equipped with other auxiliary materials, is a kind of multicomponent mixture.The major advantage of thermosol has: 1, binding speed is fast, be convenient to serialization, automatic high-speed operation, and cost is lower; 2, solvent-free public hazards are not burnt; 3, do not need drying process, adhesion technique is simple; 4, cohesive strength and snappiness are preferably arranged; 5, gloss and gloss retentivity are good.
Hot transfer printing adhesive film is dissolved in hot melt adhesive in the solvent exactly, is coated on the PET film that scribbles release layer, ink lay, after drying the product of Xing Chenging.But baling and transportation are carried out transfer printing by heat transfer machine during use, and print speed is fast, and be bonding firm, the value-added content of product height.Owing to be transferred the of a great variety of base material material, the plastics kind that caloric transfer printing technology only commonly used prints just has kind more than ten, as polypropylene, and polystyrene, polymethylmethacrylate, polycarbonate etc.It is the leather thermal transfer film of low-melting ink vehicle with the acrylic resin that people such as Zhang Zhenyu disclose a kind of in Chinese patent CN101570102A, but only leather-like materials is had better cementability, does not have versatility.At present, for different base materials,, must be unfavorable for the development of thermal-transfer line industry with different hot transfer printing adhesive films as plastics, metal, leather, timber, fabric and glass etc.
Urethane is the polymkeric substance that contains many multiple carbamate groups on the molecular backbone chain that is formed by polyisocyanates and polymer polyatomic alcohol addition polymerization, and is all better to the cohesive strength of multiple material.By the molecular structure of design urethane, use different material, chainextender and reaction conditions can obtain broad-spectrum polyurethane-hot melt transfer printing glue.
Though the report of general polyurethane hot melt is a lot, do not see the report of relevant preparation polyurethane-hot melt transfer printing glue so far.
Summary of the invention
Purpose of the present invention aims to provide a kind of preparation method of broad-spectrum polyurethane-hot melt transfer printing glue.
The present invention includes following steps:
1) poly adipate succinic acid ester is packed into container, behind the decompression dehydration, load onto stirring rod and prolong, after placing water-bath to treat the poly adipate succinic acid ester cool to room temperature again, add ditan-4,4 ' vulcabond (MDI) and catalyzer di-n-butyltin dilaurate, stir the back water-bath, temperature reaction adds small molecule chain extender again and continues reaction, gets the polyurethane-hot melt sol solution;
2) regulate the viscosity and the solid content of the polyurethane-hot melt sol solution make, be coated on the ink lay of heat transfer film, treat solvent evaporates after, ink lay promptly firmly is needed on the hot transfer printing adhesive film on the multiple materials such as metal, glass, pottery, plastics, fabric.
In step 1), the temperature of described decompression dehydration can be 110～120 ℃; The mass ratio of described poly adipate succinic acid ester, ditan-4,4 ' vulcabond, di-n-butyltin dilaurate and small molecule chain extender can be 50: (8.25～13.5): (0.5～1): (0.45～3.6); Described small molecule chain extender can be selected from 1,4-butyleneglycol or MOCA etc.; The time of described stirring can be 15～45min; The temperature of described temperature reaction can be 70～90 ℃, and the time of described temperature reaction can be 2～4h; The time of described continuation reaction can be 1～2h.
The present invention is a matrix resin with the line style hydroxyl-terminated polyurethane, adopt poly adipate succinic acid ester, ditan-4, the line style hydroxyl-terminated polyurethane hot melt transfer printing glue that 4 ' vulcabond (MDI) and small molecules dibasic alcohol and small molecules diamine are the basic raw material prepared in reaction has certain molecular weight, this polyurethane-hot melt transfer printing glue not only has good wetting property with the ink lay of heat transfer film, and and metal, glass, pottery, multiple plastics, materials such as fabric have advantages of good caking property, can with the ink lay secure bond on stock, be a kind of preparation method of broad-spectrum polyurethane-hot melt transfer printing glue.
The present invention is a kind of method for preparing transfer printing with polyurethane-hot melt transfer printing glue, and this solution is coated on the ink lay equably, treats promptly to obtain required hot transfer printing adhesive film after the solvent seasoning.The polyurethane hot melt that satisfies this application requiring not only will have suitable molecular weight to guarantee that ink lay is had good wetting property, abundant strong polarity carbamate groups can be arranged again and with material adhesive property excellences such as leather, glass, metal, timber, plastics, textiles, thereby with firm being imprinted on these article of printing ink.The viscosity of this polyurethane-hot melt sol solution is suitable on the other hand could guarantee that coating is even and thickness is suitable.
