The heat radiation prevention layer is an infrared radiation prevention adhesive layer 2 and is used for absorbing the infrared rays with a wider wave band, preferably the infrared rays with the wave band above 780nm, and can block the heat radiation to the greatest extent.
In the embodiment, the infrared-proof adhesive layer 2 is composed of infrared-proof pressure-sensitive adhesive liquid, the thickness of the infrared-proof adhesive layer 2 is 50um, the infrared-proof pressure-sensitive adhesive liquid is coated on the first substrate layer 3 through a coating machine, the infrared-proof pressure-sensitive adhesive layer adopts polyacrylate pressure-sensitive adhesive capable of absorbing a wave band above 780nm, the infrared blocking rate is more than 90%, and the glass transition temperature (Tg) value is-90 ℃ to-20 ℃; the thickness is 50um; the peeling force was 500gf/25mm. In other embodiments, the material of the infrared-proof pressure-sensitive adhesive layer is not limited, and the thickness is 5-100um, and the peeling force is 300-5000gf/25mm.

The first substrate layer 3 is arranged as an intermediate support layer between the heat radiation protection layer and the antiglare layer. Because the heat radiation preventing layer and the anti-glare layer are softer in texture, the first substrate layer 3 can make the whole film have better ductility and hardness under the condition that the middle is supported, and if the first substrate layer 3 is removed, the heat insulation effect is not affected, but the ductility and the adhesion of the whole film are poor, so that the construction difficulty is increased and the re-workability is reduced.
