Embodiment Construction
[0034] The present disclosure will be further described below in conjunction with the accompanying drawings, and the following implementations are only exemplary, and not all implementations of the technical solutions of the present disclosure.
[0035] like figure 1 , in the first aspect, a self-healing thermal insulation polyester film, comprising a self-healing coating layer 1, a PET base film layer 2, an adhesive layer 3, a first thermal insulation Layer 4, core layer 5 and second heat insulation layer 6, wherein the thickness of the self-healing layer is 1 μm to 10 μm, the thickness of the PET base film layer 2 is 12 μm to 25 μm, and the thickness of the core layer 5 The thickness is 10 μm to 20 μm.
[0036] In this solution, the thicker the self-healing layer, the better the self-healing ability, and the shorter the corresponding self-healing time. However, too thick a self-healing layer may affect the self-healing heat insulation polyester The overall performance of t...

Some embodiments of the invention provide a self-healing thermal-insulation and heat-preservation polyester film. The self-healing thermal-insulation and heat-preservation film comprises a self-healing coating layer, a PET base film layer, an adhesive layer, a first thermal-insulation and heat-preservation layer, a core layer and a second thermal-insulation and heat-preservation layer which are sequentially arranged from top to bottom, wherein the thickness of the self-healing layer ranges from 1 [mu]m to 10 [mu]m, the thickness of the PET base film layer ranges from 12 [mu]m to 25 [mu]m, andthe thickness of the core layer ranges from 10 [mu]m to 20 [mu]m; the first thermal-insulation and heat-preservation layer and the second thermal-insulation and heat-preservation layer enable the self-healing thermal-insulation and heat-preservation polyester film to have the thermal-insulation and heat-preservation capacity, so the performance of the self-healing thermal-insulation and heat-preservation polyester film is greatly optimized. In addition, due to the arrangement of the self-healing coating layer, the self-healing thermal-insulation and heat-preservation polyester film has the self-healing capacity, and the application range of the self-healing thermal-insulation and heat-preservation polyester film is widened.
Description
technical field [0001] The disclosure relates to the field of films, in particular to a self-healing heat-insulating polyester film and a preparation method thereof. Background technique [0002] With the development of the economy, the performance requirements of films in the fields of automotive film, food packaging film, and electronic optical display film are getting higher and higher. The overall aesthetics and visibility of the film are greatly damaged, and the cost of repairing such damage is high and cumbersome, which seriously hinders the further expansion of the application of the film. [0003] The films in the prior art do not have self-healing ability, which seriously restricts the application fields of the films. Contents of the invention [0004] Aiming at the technical problem that the film does not have self-healing ability in the prior art, the present disclosure provides a self-healing thermal insulation polyester film, which has self-healing ability an...
