Embodiment 1

[0026] Such as figure 1 As shown, a reflective thermal film includes a PE / PET composite film 1, a printing layer 2, a glass bead layer 3, an adhesive layer 4, an electroplating layer 5, and a hot-melt adhesive layer 6, which are laminated sequentially from bottom to top. The thickness of PE / PET composite film 1 is 2.0mm, which plays a protective role before the reflective film is hot pasted; the particle size of the glass beads is 400 mesh, and the diffuse reflection effect of the glass beads under this mesh number is good, which is comparable to that of PE / PET The composite film 1 has a large contact area to make it easy to peel off; the adhesive layer 4 uses polyurethane glue with a thickness of 10 μm; the electroplating layer 5 is an aluminum layer with a thickness of 20 nanometers, which plays a reflective role; the hot-melt adhesive layer 6 is a conventional hot-melt adhesive in the market , Play the role of thermocompression bonding. The components of the printing layer...

Embodiment 2

[0035] A reflective thermal film, comprising a PE / PET composite film 1, a printing layer 2, a glass bead layer 3, an adhesive layer 4, an electroplating layer 5, and a hot-melt adhesive layer 6, which are laminated sequentially from bottom to top. PE / PET composite film 1 has a thickness of 1.0 mm; the particle size of the glass beads is 450 mesh; the adhesive layer 4 uses bright silver glue, which can play a reflective effect; The adhesive layer 6 is a conventional hot melt adhesive in the market. The components of the printing layer 2 are made up of the following raw materials in parts by weight: 10 parts of nano silicon dioxide, 10 parts of superfine calcium carbonate, 10 parts of silane coupling agent, 30 parts of polyvinyl alcohol, 5 parts of boric acid, and 150 parts of ionized water, the average particle size of the nano silicon dioxide is 90 nanometers, the molecular weight of the polyvinyl alcohol is 5000, and the thickness of the printing layer is 20 μm.

Abstract

The invention relates to the technical field of reflective materials, and provides a reflective hot applied film and a preparation method thereof. The reflective hot applied film comprises a PE / PET composite film, a glass bead layer, an adhesive layer, an electroplated layer and a hot melt adhesive layer which are laminated and arranged sequentially from bottom to top, wherein glass beads have a particle size of 200-500-mesh. The defects that in the prior art, a PE / PET composite film on the surface of a reflective film cannot be torn easily, and further printing cannot be performed on the surface of the reflective film in the later stage are overcome.

Description

technical field [0001] The invention relates to the technical field of reflective materials, in particular to a reflective thermal film and a preparation method thereof. Background technique [0002] Reflective thermal film, also known as "hot film", is a layer of hot melt adhesive attached to the back of the adhesive layer with reflective elements. Generally, it is ironed in strips with an electric iron or a hot ironing machine under a certain pressure and temperature. , Its reflective brightness is strong, it is resistant to washing and abrasion, and can be attached to different substrates such as TPU, PVC, PU, ​​cloth, clothing, webbing, shoes, etc., and lettering, trademarks, etc. Under the circumstances, it can play the role of safety warning and has certain aesthetics. [0003] Patent document CN201520400164 discloses a single-layer reflective thermal film, including a PE / PET composite film layer, a glass bead layer, a focusing layer, a coating layer and a hot-melt co...
