Description
Technical field
The present invention relates to a kind of emerging printing technologies --- thermal transfer technology more particularly to a kind of thermal transfer coating and its
Application in heat sublimation technique.
Background technique
Thermal transfer be it is a kind of it is economical, efficiently, the printing technology of high-quality, can be widely applied to textile, plastics, ceramics,
The picture on surface of the material products such as metal is printed.Different from traditional mode of printing, the technology point of thermal transfer technology is to turn
The dyestuff on printing paper surface is penetrated into body surface, forms image beautiful in colour, that high definition is true to nature after sublimating by heat sublimation.Its figure
Case without feel, do not fall off, be cracked, it is durable, have efficiently, environmental protection, technique flexibly, operate the skills such as convenient, image individuation
Art feature.
Thermal dye sublimation transfer printing is a kind of water-free dyeing technique, environmental protection effect with higher, the high energy advocated current country
Consuming industry energy-saving emission reduction improvement project has important value, has become research hotspot at present.The principle of thermal dye sublimation transfer printing is in height
Under temperature (usually 220 DEG C or more), the disperse dyes on thermal dye sublimation transfer printing medium are sublimed up on chemical fiber plus material and directly by fabric
Fiber is fixed, and the chemical fiber plus material printed and dyed can be with Non-water washing.It is believed that thermal dye sublimation transfer printing technique, especially digital heat sublimation
Transfer printing process is a kind of high in environmental protection and practical reliable technique, is hopeful to substitute traditional dyeing and finishing technique.
Thermal dye sublimation transfer printing medium is the technological core place of entire technique, especially coating formula technology.Firstly, the coating
Recipe requirements can receive ink well and form fine and smooth pattern, can discharge disperse dyes when heated, rise it sufficiently
China forms the higher heat sublimation rate of transform.But due to the limitation of current technology, existing product applies during heating
Layer is easy to not played high temperature due to resistance to and dizzy opened.
Chinese patent 201610301625.0 discloses a kind of thermal transfer coating, contains the following parts by weight：
Wherein, the modified epoxy is polyphenol type modified epoxy, and molecular structure is as follows：
Wherein, the integer that n is 1 to 7.
Advantage of the invention is that：1, the coating of moderate gel time and curing time, generation have excellent inherence
The removing of quality, transfer paper is easier, and the clean mark of the pattern transferred.2, the coating vitrifying with higher generated
Temperature Tg, crosslink density is high, can play a part of to protect pattern in large temperature range, have long-effective corrosion effect.Additionally
Sundries adherency, deposition can be prevented, daily maintenance cleaning is reduced.3, the coating generated is fine and close, tough and tensile, wear-resisting, has good
Impact resistance, flexibility and cohesive force, the external force that can be resisted in construction was destroyed, with 10 years or more service life.4, described
The production craft step of coating is simple, low in cost, high production efficiency.But in the invention, the temperature of thermal transfer is 190 DEG C, temperature
Degree is higher, and energy consumption is higher.
Chinese invention patent 201710349948.1 discloses a kind of polyester-type thermal transfer coatings for aluminum coil, it is characterised in that：
It comprises the following components in parts by weight：
The minimum film formation temperature of the polyester-type thermal transfer coatings for aluminum coil is 200 DEG C.Polyester-type thermal transfer volume of the invention
The image color of aluminium paint transfer is bright-coloured, level is abundant, and transferring effect can compare favourably with printing, be with the difference of printing technology
Thermal transfer is to make ink by heat sublimation at high temperature, and energy multicolor patterns once at figure, are not necessarily to chromatography, it is bright to form color after sublimating
Beautiful pattern, and the inside of coating can be penetrated into, so thermal transfer product is durable, transfer pattern will not fall off, be cracked and
It fades, the original glossiness of product, wearability, weatherability, resistance to acid and alkali will not be changed because of thermal transfer processing, and after coating
It is easy to remove with thermal sublimation pattern, is applicable to various colors and gloss coating.In the invention, heat sublimation temperature is higher, energy consumption compared with
Height, pattern penetrate into coat inside by heat sublimation, and the combination of pattern and coating is not secured enough.
Therefore need one kind that can also dyestuff be made sufficiently to distil at a lower temperature, obtained pattern is more firm, and it is prominent, no
It is easy to fall, thus the further development to promote heat sublimation technique.
Summary of the invention
The present invention provides a kind of thermal transfer coatings, it can also can make dyestuff sufficiently distil, obtain at a lower temperature
