Technical Field

[0001] The utility model relates to the technical field of heat transfer films, in particular to a high temperature resistant heat transfer film. Background Art

[0002] Heat printing is a traditional Chinese art that uses a hot iron to iron out marks on objects to achieve the purpose of painting. Currently, heat printing is commonly seen on clothing. Heat printing is printed on clothing through a heat printing machine to beautify the clothing. When heat printing, the heat printing film on the clothing is indispensable.

[0003] The current heat transfer film has a simple structure. When exposed to high temperatures and sunlight, the heat transfer film is prone to fall off. When clothes are washed and stirred, the heat transfer film is rubbed and folded, which will damage its structure and eventually cause fading or bubbling, affecting its service life.

After the heat transfer is completed, an upper thermal insulation layer 1 and an upper thermal insulation layer 2 are fixedly connected to the upper surface of the heat transfer layer by bonding to perform double-layer thermal insulation, thereby reducing the influence of external high-temperature exposure heat on the base layer and the heat transfer layer. A protective film is connected to the upper surface of the upper thermal insulation layer 2, the thickness of the base layer is greater than the thickness of the lower thermal insulation layer, the elastic layer being arranged can increase the elasticity of the entire film body, can quickly recover after deformation, and avoid adverse effects of long-term deformation on the film body, and the upper thermal insulation layer 2 and the upper thermal insulation layer 1 are transparent.

The aramid fiber 1 and aramid fiber 2 of the upper insulation layer 1 and the upper insulation layer 2 are woven in different ways to make the double-layer insulation effect better.

[0007] As a preferred technical solution of the utility model, the elastic layer is composed of two layers of elastic material and a silicone sphere layer. The diameter of the silicone spheres in the silicone sphere layer for the membrane is between 0.1 and 0.15 mm. The upper and lower parts of the silicone sphere layer are fixedly connected with elastic materials. The lower elastic material is connected to the second upper insulation layer, and the upper elastic material is connected to the lower surface of the protective film. Since the silicone sphere layer is used in the elastic layer, it can play a certain insulation role. Secondly, the silicone sphere layer and the elastic material have good elasticity. When the membrane is deformed, the elastic layer can effectively recover.

[0008] As a preferred technical solution of the utility model, the elastic material is a polyester layer, and a number of penetrating empty groove areas are evenly distributed on the polyester layer, which has a certain air permeability.

[0009] The beneficial effects of the utility model are as follows: by arranging a double-layer heat-insulating structure consisting of an upper heat-insulating layer 2 and an upper heat-insulating layer 1 above the heat-insulating layer, the high-temperature resistance of the film body is improved, and when the film body is exposed to high temperature from the outside, the influence of the exposure on the heat-insulating layer is reduced; the elastic layer and the lower heat-insulating layer can reduce the influence of the high-temperature exposure on the sol layer to avoid falling off; at the same time, the arrangement of the elastic layer can increase the overall elasticity of the film body, and when the film body is deformed under the action of external force, it can recover in time to avoid cracking, thereby reducing the overall service life of the film body and facilitating the long-term use of the film body.
