Description
Technical field
The invention belongs to Material Field, and in particular to a kind of high temperature resistant coil coating for being coated on Kapton surface
And its preparation method and application.
Background technology
Thermal transfer belongs to specialty printing, there is the development advanced by leaps and bounds in recent years, and it is mainly characterized by transferred image color
Color bright-coloured, level enriches, and its effect can compare favourably with printing.It is that thermal transfer is to make heat at high temperature with printing difference
Transfer ink receives heat sublimation, penetrates into body surface, and the beautiful image of color is formed after sublimating.So, thermal transfer product is prolonged
Durable, image will not fall off, is cracked and fade.Thermal transfer coating is a kind of high temperature resistant, and can be various in its surface printing
The special coating of color ink, dedicated for thermal transfer counterdie application.Emerging for thermal transfer coating means that Thermal-printing Technology exists
Application in life will infinitely extensively, coating can directly and simplicity is sprayed in any material, greatly reduce production cost,
Make the more simple and direct facility of production process, no longer by transporting, the factor such as region and material limited, really realize Thermal-printing Technology
Personalized application.
Coil coating is the method by roller coat operation, and coating is coated on the surface of coiled material, is then made pre-coated coil
(Coil Coating Products), have the advantages that specious, paint film is uniform, beautiful in colour, intensity is high, machine-shaping is convenient, and can drop
Low cost, while utilization efficiency of coatings substantially achieves 100%, so as to reduce pollution；Coil coating is to shared ground space
It is required that relatively low, construction investment is low；In most cases, the solvent of coil coating has been incinerated, thus reduce fire and
Toxic hazard, reduces the discharge of VOC.Therefore, coil coating obtains extensive accreditation and applies.
Thermal transfer coating is mainly used in ceramics, stone material, metal material etc., typically has pigment higher, table high
Face tension force, heat resistance is good, but mechanical property is not good, it is impossible to for realizing thermal transfer on thin-film material class coiled material.When
When Kapton is used for packaging material, one layer is coated with high temperature resistant protective action to meet Thermal-printing Technology demand needs
White coil coating.The coating it is also desirable to have temperature tolerance high and higher while possessing coil coating various performances
Surface tension.And when using conventional silicone resin system, the good mechanical properties of film, but surface tension is relatively low, and it is pure
The surface tension of organic siliconresin in 24dyn/cm or so, after being made the coil coating of physics satisfactory mechanical property, open by its surface
Power can only arrive 30dyn/cm or so, and the surface tension range of ink in 30~36dyn/cm, and this just makes the ink cannot be by heat
Transfer technique equably spreads over film coated surface.
Therefore, in the urgent need to coil coating of the exploitation with high temperature resistant, good surface tension force is thin to be coated on polyimides
The coiled material surfaces such as film realize the thermal transfer of coiled material.
The content of the invention
It is an object of the invention to provide a kind of high temperature resistant coil coating for being coated on Kapton surface and its preparation
Methods and applications, solve the problems, such as that conventional coil coating cannot realize that high temperature resistant and thermal transfer and conventional thermal transfer coating cannot
It is applied to the problem of coiled material surface.
To reach above-mentioned purpose, main technical schemes of the invention are as follows：
A kind of high temperature resistant coil coating for being coated on Kapton surface, it includes first component and curing agent, solidification

Preferably, described methylphenylsiloxane is DC-805 or W-1053.
Preferably, the high temperature resistant coil coating for being coated on Kapton surface of the present invention, it includes first component
And curing agent, curing agent accounts for the 0.5~3.0% of first component gross mass；The first component includes 20.0~50.0% aminomethyl phenyls
Organic siliconresin, 10.0~15.0% rutile type titanium whites, 5.0~10.0% blanc fixes, 1.0~3.0% alumina silicate,
1.0~2.0% organo-silicon compound ADP, the mixed liquor of 20.0~63.0% toluene, dimethylbenzene and mixed dibasic acid ester, with matter
Amount percentage meter.
Conventional thermal transfer coating realizes surface by improving the consumption of powder (high temperature resistant filler and constitution filler) merely
The raising of power, but the mechanical performance of paint film can be influenceed；Or surface tension is improved by adding larger amount of organic resin, but
The temperature tolerance of paint film can be influenceed.Creatively be applied in coil coating for alumina silicate, kaolin first by the present invention, Main Function
It is the surface tension for adjusting paint film, it is final to coating surface to realize that thermal transfer plays decisive role.The present invention is using described
Surface tension accelerator can significantly improve the surface tension of paint film in the case where its addition is little, meanwhile, alumina silicate,
Temperature tolerance is good in itself for kaolin, and the heat resistance of paint film will not be also influenceed because addition is excessive.
In the present invention, the effect of described matrix resin is that filming function is mainly played in coating, and for adhering to various solids
Filler, the temperature tolerance to paint film is acted on significantly raising；High temperature resistant filler Main Function in coating is to improve to apply
The temperature tolerance of material and the covering power of increase paint film, while regulation paint liquid status can be played a part of；The constitution filler be
Filling effect is mainly played in coating, and plays a part of reduces cost；The adhesion promoter is that the effect in coating is
Improve the adhesive force of paint film.
