Embodiment 1

[0023] Weigh 10 parts of main agent, 2.5 parts of hardener and 3 parts of methyl ethyl ketone, and mix and stir for 25 minutes. The mixed mixture is coated with a 180-mesh screen roller at a coating temperature of 135 degrees Celsius, and then the semi-finished product is placed in 50 degrees Celsius The finished product can be obtained in the curing room for 120 hours.

Embodiment 2

[0025] Weigh 11 parts of main agent, 2 parts of hardener and 3 parts of methyl ethyl ketone. The mixed mixture is coated with a 180-mesh screen roller at a coating temperature of 150 degrees Celsius, and then the semi-finished product is placed in a 55 degrees Celsius curing room for 120 hours. You can get the finished product.

Embodiment 3

[0027] Weigh 9 parts of main agent, 3 parts of hardener and 4 parts of methyl ethyl ketone. The mixed mixture is coated with a 175-mesh screen roller at a coating temperature of 120 degrees Celsius, and then the semi-finished product is placed in a 45 degrees Celsius curing room for 120 hours. You can get the finished product.

[0028] Example Description:

[0029] The main agent used in Examples 1-3 is a thermosetting resin, the solid content of the main agent is 35%, the solid content of the hardener is 50%, and the viscosity of the main agent and the hardener are both 800-1200CPS.

[0030] After long-term practice, Example 1 is the best example, which has the best matte effect and good adhesion at low temperature or normal temperature. However, it should be pointed out that Example 2 and Example 3 have excellent performance in specific environments, and those of ordinary skill in the art can also simply modify the formulations or preparation methods of Examples 1-3 accordi...

Abstract

The invention relates to a heat transfer printing film, and in particular, relates to a smooth high-matte film, wherein the smooth high-matte film consists of the following components in parts by weight: 8-12 parts of a main agent, 1-3 parts of a hardener and 2-4 parts of butanone. A preparation method comprises the steps: weighing the main agent, the hardener and butanone respectively, and mixingand stirring for 20-30 minutes; and coating the mixture after mixing with a 175-180-mesh mesh roller at the coating temperature of 120-150 DEG C, then putting the semi-finished product into a 45-55 DEG C curing room for 120 hours, and thus obtaining the finished product. The low temperature matte effect of a coating film is good; the smooth high-matte film has good compatibility and adhesion witha PET film, and is suitable for matte face treatment of the PET transparent film.

Description

technical field [0001] The invention relates to a thermal transfer film, especially a glossy high-grade film. Background technique [0002] In the existing heat transfer film with matte effect, the matte material is generally attached to the film material regionally. For example, a Chinese patent discloses a carrier film, patent No. zl200520119732.9. The carrier film includes a transparent polyester film and a matt material layer, and the matt material layer is regionally attached to the polyester film to make the polyester film The surface of the ester film has matt and non-matt regions that reflect light to different degrees. [0003] The hotspot of the prior art is that its attachment requires the use of a carrier, and it cannot be directly used on a PET film. It lacks compatible adhesion to PET film. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention provides a film body with good matt effect and compatible adhesion...
