Description

Repeatedly usable's reflective membrane

The technical field is as follows:

the utility model belongs to the technical field of reflective materials, and particularly relates to a reusable reflective film.

Background art:

PMM or PVC is used as a surface layer of a reflective film used on a passenger car, and the glass microsphere reflective pressure-sensitive reflective material after metal coating is used. When the reflective material is used, the incident light is reflected back by utilizing the reflective property of the reflective material, so that the reflective material is widely applied to the fields of traffic, fire fighting, railways and the like, and the existence of a wearer is highlighted through the reflective property of the reflective material so as to improve the safety.

At present, the reflective membrane that uses the acrylic acid pressure sensitive adhesive as the reflective membrane of basic unit on using the most common passenger train, but single acrylic acid pressure sensitive adhesive, difficult accomplish to tear out again and do not remain the pressure sensitive adhesive on the passenger train automobile body after pasting in the surface of passenger train automobile body, because the contact of pressure sensitive adhesive two sides all is aluminium metal, and polarity is close, leads to the pressure sensitive adhesive both sides all to have remaining possibility. Therefore, when the reflective film on the passenger car is replaced at every time, the residual adhesive needs to be removed with great manpower and energy, the operation is very inconvenient, and meanwhile, the paint on the car body is damaged.

The utility model content is as follows:

the utility model aims to provide a reusable reflective film which can be easily torn off from a passenger car body, does not leave residual glue and effectively protects car paint.

The utility model is realized by the following steps:

the utility model provides a repeatedly usable's reflective membrane, includes surface course, cloth pearl layer, focusing layer, aluminize layer, polyurethane layer and the pressure sensitive adhesive layer that from top to bottom sets gradually, be provided with the glass microballon between cloth pearl layer, the focusing layer, the setting of glass microballon tiling, the surface course is the PMMA layer.

In the reusable reflective membrane, the release paper is arranged on the bottom surface of the pressure-sensitive adhesive layer.

In the reusable reflective film, the refractive index of the glass beads is 1.9-1.95.

In the above reusable light reflecting film, the diameter of the glass beads is 30 μm to 100 μm.

In one of the above reusable retroreflective sheeting, the thickness of the polyurethane layer is 20 to 25 μm.

In one of the above reusable retroreflective sheeting, the thickness of the top layer is 40 μm to 60 μm.

In the above reusable light reflecting film, the thickness of the bead layer is 26 μm to 30 μm.

In the above reusable light reflecting film, the thickness of the focusing layer is 18 μm to 20 μm.

In the reusable reflective film, the thickness of the pressure-sensitive adhesive layer is 40 to 60 μm.

Compared with the prior art, the utility model has the outstanding advantages that:

1. the polyurethane layer is arranged between the aluminum-plated layer and the pressure-sensitive adhesive layer, and the polyurethane layer can change the polarity of the two bonding surfaces of the pressure-sensitive adhesive, so that the affinity of the pressure-sensitive adhesive to the reflective film is greater than that of the car body, the pressure-sensitive adhesive can be easily torn off from the car body of the passenger car, no adhesive residue is left, and the car paint is effectively protected;

2. the utility model can be repeatedly used, reduces the difficulty of film pasting, can be torn and pasted again, ensures the surface smoothness, does not wrinkle and reduces the use cost;

3. the utility model has wide application range, can be suitable for various car stickers, and can also be used as license plate stickers and the like.

Description of the drawings:

fig. 1 is a schematic cross-sectional view of the present invention.

In the figure: 1. a surface layer; 2. a layer of cloth beads; 3. a focusing layer; 4. plating an aluminum layer; 5. a polyurethane layer; 6. a pressure sensitive adhesive layer; 7. glass beads; 8. and (4) release paper.

The specific implementation mode is as follows:

the utility model is further described below in specific embodiments, with reference to fig. 1:

the utility model provides a reusable reflective membrane, which comprises a surface layer 1, a cloth bead layer 2, a focusing layer 3, an aluminum-plated layer 4, a polyurethane layer 5 and a pressure-sensitive adhesive layer 6 which are sequentially arranged from top to bottom, wherein the cloth bead layer 2 is made of an acrylic resin material, glass beads 7 are arranged between the cloth bead layer 2 and the focusing layer 3, the glass beads 7 are flatly laid, and the surface layer 1 is a PMMA layer.

Because the pressure-sensitive adhesive layer is suitable for being attached to bodies of buses or buses and the like, and the pressure-sensitive adhesive layer 6 has certain viscosity, when the pressure-sensitive adhesive layer is not used, the release paper 8 is arranged on the bottom surface of the pressure-sensitive adhesive layer 6. When pasting, the release paper 8 is torn off.

According to the utility model, the polyurethane layer 5 is arranged between the aluminum coating layer 4 and the pressure-sensitive adhesive layer 6, and the polyurethane layer 5 can change the polarity of the two sides bonded by the pressure-sensitive adhesive, so that the affinity of the pressure-sensitive adhesive to the reflective film is greater than that of the car body, and the pressure-sensitive adhesive can be easily torn off from the car body of the passenger car without residual adhesive.

Specifically, the refractive index of the glass beads 7 is 1.9-1.95. The diameter of the glass beads 7 is 30-100 μm. The thickness of the polyurethane layer 5 is 20-25 μm.
