Problems solved by technology

[0003] However, the current use of retroreflective products is mostly to add retroreflective materials into the paint, and to achieve the reflective effect by painting and other construction techniques on the surface where it needs to be used. This cumbersome construction process has limited its use in more Many commercial or industrial applications

Embodiment Construction

[0018] In order to make the technical means, creation features, achievement goals and effects of the present invention easy to understand and understand, the following description will be further elaborated with reference to the specific figures.

[0019] like figure 1 , figure 2 shown,

[0020] A sticker type retroreflective film is composed of a four-layer structure. The four-layer structure is, from top to bottom, a protective layer 1, a retroreflective layer 2, an adhesive layer 3, and a base material layer 4. The base material layer 4 It is composed of three parts: base material 5, adhesive 6 and isolation film 7.

[0021] Preferably, the protective layer 1 is a layer of transparent material, which is a composite of one or more of polyethylene film, polypropylene film, polystyrene film, polyvinyl chloride film, polyester film and polyamide film. to make.

[0022] Preferably, the retroreflective layer 2 is composed of several retroreflective microstructures.

Abstract

The invention relates to a sticking type retroreflective film, successively comprising four layers from top to bottom: a protection layer, a retroreflective layer, a sticking layer and a substrate layer, wherein the substrate layer is composed of a base material, an adhesive and an isolating film. A preparation method comprises: first, uniformly spraying the sticking layer on the surface of the substrate layer to form a stable structure; secondly, before complete solidification of the sticking layer, uniformly spraying the retroreflective film on the surface of the sticking layer; and finally, covering the transparent sticking layer on the surface of the retroreflective film to form the sticking type retroreflective film. The sticking type retroreflective film is prepared by employing four layer composite technology, and is simple and convenient to use; through a retroreflective microstructure, the sticking type retroreflective film possesses excellent retroreflective effects; an outer layer is covered by the protection layer, thereby prolonging the service life; meanwhile, preparation processes are simple, and raw materials are easy to obtain, thereby facilitating processing line production.

Description

technical field [0001] The invention belongs to the technical field of optics, and particularly relates to a sticker type retroreflective film and a preparation method thereof. Background technique [0002] Retroreflective film has been widely used in traffic safety facilities, personal safety, billboards and other fields. Among them, it has broad application prospects in traffic facilities, such as warning signs on vehicles, warning signs and instructions on roads, navigation signs, etc., which provides a strong guarantee for people to travel safely. With the maturity of reflective film technology, the effect of warning and eye-catching effects has also been vigorously promoted in other related fields. For example, adding reflective film to billboards can enhance visual effects, and adding reflective film to factory signs can be ordered. management, etc. [0003] However, most of the current retro-reflective products are used to add retro-reflective materials to the paint...
