preparation example Construction

[0027] A method for preparing a long-lasting high-brightness reflective sheet, the steps comprising:

[0028] ①Aluminum steaming: evaporate nano-aluminum in an oxygen-free environment at a temperature of 1500°C and attach it to the front of the PVC base layer to form a reflective layer;

[0029] ② Coating: Mix 100 parts of transparent polyester resin, 15-20 parts of luminous microcapsules, 5 parts of anti-settling agent, and 5 parts of diluent at a temperature of 200-220 ° C, and then evenly coat Distributed on the outer surface of the reflective layer, cooled to form a fluorescent layer;

[0030] ③ Coating: A layer of anti-oxidation film is covered on the fluorescent layer as a protective layer.

Embodiment 1

[0033] ① Evaporate nano-aluminum in an oxygen-free environment at a temperature of 1500°C and attach it to the front of the PVC base layer 1 to form a reflective layer 2;

[0034] ②Mix 100 parts by mass of transparent polyester resin, 15 parts by mass of luminous microcapsules 31, 5 parts by mass of anti-settling agent, and 5 parts by mass of diluent at a temperature of 220°C, and then evenly coat it on the outside of the reflective layer 2 The surface is cooled to form a fluorescent layer 3;

[0035] ③ Cover the fluorescent layer 3 with an anti-oxidation film as the protective layer 4 .

[0036] refer to figure 1 The reflective sheet includes a PVC base layer 1, a nano-aluminum reflective layer 2 located on the front of the base layer 1, a fluorescent layer 3 containing luminous microcapsules 31 located on the outer surface of the reflective layer 2, and an anti-oxidation protective layer coated on the outer surface of the fluorescent layer 3 4.

[0037] Since the main com...

Embodiment 2

[0039] ① Paste the pressure-sensitive adhesive 5 with the release paper 6 as the substrate on the back of the PVC base layer 1;

[0040] ② Evaporate nano-aluminum in an oxygen-free environment at a temperature of 1500°C and attach it to the front of the base layer 1 to form a reflective layer 2;

[0041] ③ Mix 100 parts by mass of transparent resin, 20 parts by mass of luminous microcapsules 31, 5 parts by mass of anti-settling agent, and 5 parts by mass of diluent at a temperature of 200°C, and then evenly coat the outer surface of the reflective layer 2, cooling to form the fluorescent layer 3;

[0042] ④ Cover the fluorescent layer 3 with an anti-oxidation film as the protective layer 4 .

[0043] refer to figure 2 , The difference from Example 1 is that the back of the reflective sheet has a pressure-sensitive adhesive 5, and the release paper 6 can be torn off during use to attach the reflective sheet to the surface of the object that needs to be marked, which is conve...

Abstract

The invention discloses a long-acting high-brightness light-reflection sheet and a preparation method thereof. The light-reflection sheet comprises a base layer and a light-reflection layer coating the surface of the base layer. The outer surface of the light-reflection layer is also coated with a fluorescent layer comprising noctilucence microcapsules. The preparation method comprises carrying out aluminium evaporation on the base layer to form the light-reflection layer; coating the surface of the light-reflection layer with transparent resin comprising the noctilucence microcapsules to form the fluorescent layer; and coating an antioxidation film protection layer on the fluorescent layer. Through adding the fluorescent layer to the light-reflection surface, the light-reflection sheet is allowed to store optical energy and can release bright visible light for a period after entering an absolute black environment, and thus the light-reflection sheet is wider in suitable application range.

Description

【Technical field】 [0001] The invention belongs to the technical field of reflective sheets, in particular to a reflective sheet with high reflected light intensity and long lasting effect. 【Background technique】 [0002] Reflective sheet is a kind of marking and warning that uses the principle of light reflection. Its characteristic is that it can convert weak light into bright and visible reflected light, making it easy to observe the marked people or objects and prevent accidents in the dark. [0003] The advantage of the reflective sheet is that it does not need its own light source, but is illuminated by the low light of the environment, which has the effect of energy saving. But if it is in a pure black environment where the power is suddenly cut off, because there is no external light source, the reflective sheet will not work, which limits its application. [0004] Therefore, it is necessary to provide a new long-lasting high-brightness reflector to solve the above p...
