Problems solved by technology

The service life of the PMMA surface reflective film is generally longer, which can reach more than 10 years. However, the original PMMA film used is mostly purchased from foreign products, such as Japan Kanka Chemical, Germany Evonik, etc. The price is very high, which seriously raises the price of the reflective film. overall manufacturing cost of

Embodiment 1

[0027] as attached Figure 1~3 As shown, this embodiment provides a kind of aging-resistant reflective film, which is a microcrystalline cubic structure, specifically an equilateral triangular pyramid structure, the side length of the equilateral triangle at the bottom is L1=L2=L3=110 microns, and the height H=50 microns , The angles between the sides 6, 7, and 8 of the cubic structure and the bottom surface are all 59°, and the angles between the three sides of the triangular pyramid are 90°. The reflective film includes an aging-resistant coating 1 , a prism reflective layer 2 , an air capsule support layer 3 , an adhesive layer 4 and a release layer 5 from outside to inside in sequence.

[0028] Specifically, the preparation method of the reflective film includes the following steps:

[0029] S1, coating acrylic resin coating B on the polyester film A (PET film A) of 50 micron thickness, after oven drying, form aging-resistant coating 1, then carry out winding; Wherein, ac...

Embodiment 2

[0036] as attached Figure 1~3 As shown, this embodiment provides a kind of aging-resistant reflective film, which is a microcrystalline cubic structure, specifically an equilateral triangular pyramid structure, and the side length of the equilateral triangle at the bottom is L1=L2=150 microns, L3=165 microns, height H =72 microns, the side 6 of the cubic structure, the angle between the side 7 and the bottom surface is 59°, the angle between the side 8 and the bottom surface is 54°, and the angle between the three sides of the triangular pyramid is 90°.

Abstract

The invention is applicable to the technical field of road traffic safety, and provides an anti-aging reflective film and a preparation method and application thereof, the reflective film is of a micro-crystalline cubic structure, and sequentially comprises an anti-aging coating, a prism reflective layer, an air capsule support layer, a gum layer and a release layer; the anti-aging coating is prepared from the following components: methyl methacrylate, 2-aminoethyl methacrylate, ethyl acetate, an initiator, an ultraviolet light absorber and a light stabilizer; and the prism reflective layer ismade of polycarbonate resin or polyvinyl chloride resin. The reflective film provided by the invention is of a micro-crystalline cubic structure, and a resin material with a relatively low refractiveindex is used for replacing glass beads with a high refractive index, so that the reflective film has more excellent retro-reflection performance. In addition, the reflective film adopts the anti-aging coating with a special formula, so that the anti-aging effect of the reflective film can be ensured to reach 7 years or more, and the production cost can be greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of road traffic safety, and in particular relates to an anti-aging reflective film and a preparation method and application thereof. Background technique [0002] The reflective film is a functional material that uses its specific structure to realize the return of the incident light after it enters it. In principle, reflective film is divided into two categories: glass bead type and micro prism type. The glass bead type is divided into lens embedded type and sealed capsule type. These two types of glass bead-type reflective film have poor reflective effect, complex production process, high energy consumption, and environmental pollution problems, and are currently being gradually eliminated. The micro-prism type reflective film has good reflective effect and less production process steps, and is becoming the mainstream product in the market. Especially developed countries in Europe and the United States ...
