Embodiment 1

[0068] Such as figure 1 , figure 2 As shown, a diaphragm with dual effects of reflection and transmission includes a reflective layer 1, a pressure-sensitive adhesive layer 3, and a release layer 4. The lower surface of the pressure-sensitive adhesive layer 3 is bonded to the upper surface of the release layer 4. Then, it also includes a transmissive layer 2, the upper surface of the transmissive layer 2 is bonded to the lower surface of the reflective layer 1, the lower surface of the transmissive layer 2 is bonded to the upper surface of the pressure-sensitive adhesive layer 3, and the transmissive layer 2 is provided with fine particles 21 .

[0069] Preferably, the reflective layer 1 includes a highly transparent weather-resistant layer 11 and a microstructure reflective layer 12, the upper surface of the microstructure reflective layer 12 is bonded to the lower surface of the highly transparent weather-resistant layer 11, and the microstructure reflective layer The low...

Embodiment 2

[0087] In the step (b), take the binder, the fine particles 21, the dispersant, the wetting agent, the light stabilizer, the ultraviolet absorber and place all the components in a closed container with a stirring device and a cooling jacket. In the container, after high-speed stirring, all components are dispersed and mixed uniformly to prepare a mixture, and then the mixture is made into a film with a thickness of 70um to form the transmission layer 2 .

[0088] Other implementations are the same as in Example 1.

Embodiment 3

[0090] In the step (b), take the binder, the fine particles 21, the dispersant, the wetting agent, the light stabilizer, the ultraviolet absorber and place all the components in a closed container with a stirring device and a cooling jacket. In the container, after high-speed stirring, all components are dispersed and mixed uniformly to prepare a mixture, and then the mixture is made into a film with a thickness of 40um to form the transmission layer 2 .

[0091] Other implementations are the same as in Example 1.

Abstract

The invention discloses a diaphragm with dual-effects of reflecting and transmission and a manufacturing method thereof. The diaphragm comprises a reflecting layer, a pressure-sensitive adhesive layerand a release layer, and the pressure-sensitive adhesive layer is adhered with the release layer; the diaphragm further comprises a transmission layer adhered with the reflecting layer and adhered with the pressure-sensitive adhesive layer, and fine particles are arranged in the transmission layer. The transmission layer is arranged at a lower surface of the reflecting layer, the light intensityattenuation when irradiation light ray of an external lighting source irradiating from an upper surface of the reflecting layer penetrates the transmission layer arranged at the upper surface of the reflecting layer in the prior art is fundamentally solved, and the defect that the product is short in service life since the transmission layer on the upper surface of the reflecting layer quickly ages after being influenced by the light, the moisture, the temperature change and like external environment factors in the prior art is effectively solved; the reflected light intensity of the product is greatly improved, the service life of the product is effectively prolonged when the reflecting performance, the caution and identification effects of the product are effectively improved.

Description

technical field [0001] The invention relates to a diaphragm for road traffic signs, in particular to a diaphragm with dual functions of reflection and transmission and a manufacturing method thereof. Background technique [0002] Traditional road traffic signs are usually made by pasting the reflective film on a rigid substrate, because the unique internal structure of the reflective film allows the light to reflect back to the light source along the incident direction. At night or in a dark environment, as long as there is When illuminated by the light source, the strong retroreflective light of the reflective film can make the vehicle drivers and passengers clearly identify the content of the sign, and play a very good role in safety warning and indication. However, the passive reflective feature of reflective film has also exposed some disadvantages in today's society where traffic participants are more and more extensive, participation behaviors are becoming more and mor...
