First embodiment
Referring to fig. 1 to 4, a first embodiment of the present invention provides a fire hose 100 with a reflective mark, the fire hose 100 includes a first end 101 connected to a hydrant (not shown) and a second end 102 connected to a water gun (not shown). At least one reflection of light sign is attached on the surface of fire hose 100, including the portion of intaking 10 towards the first end and the play water portion 20 towards the second end, promptly when fire hose 100 connects the completion back, the portion of intaking 10 towards the fire hydrant, goes out water portion 20 towards the squirt.
Referring to fig. 2, the water inlet portion 10 and the water outlet portion 20 have different shapes, so that the personnel in the fire scene can determine the outlet of the fire scene according to the reflective marks to guide the direction of the personnel in the fire scene. In this embodiment, the shape of the water inlet part 10 is rectangular, the shape of the water outlet part 20 is triangular, the water inlet part 10 and the water outlet part 20 jointly form an arrow shape, and the arrow direction is the direction of water flow in the fire hose. In other embodiments, the water inlet portion 10 and the water outlet portion 20 may be formed in other shapes.
Referring to fig. 3, the reflective mark is provided with a protective layer 30, a reflective layer 40, an adhesive layer 50 and a peeling layer 60 in order from top to bottom in a thickness direction. The thickness of the reflecting layer 40 is 100-200um, and the reflecting layer comprises a micro prism layer 41 and a plating layer 42, wherein the micro prism layer 41 is used for refracting light rays in multiple angles, the micro prism layer 41 is formed by imprinting after being solidified by a high-light-transmittance UV coating, and the plating layer 42 is an aluminum film sprayed on the surface of the micro prism layer 41 by a magnetron sputtering process.
Referring to fig. 4, the outer surface of the micro prism layer 41 is a concave-convex micro-nano structure (not labeled), the concave-convex micro-nano structure includes a first surface 411, a second surface 412 and a third surface (not shown), the first surface 411, the second surface 412 and the third surface form a conical protrusion, and the plurality of conical protrusions form the concave-convex micro-nano structure. When light rays with the same angle irradiate the micro prism layer 41, the light rays form refracted light rays with different angles after passing through the first surface 411, the second surface 412 and the third surface. Compared with the traditional glass bead reflecting mark, the microprism structure has more obvious brightness and better indication effect.
In this embodiment, the pyramid on the concave-convex micro-nano structure is a triangular pyramid, and includes 3 non-parallel inclined planes. In other embodiments, since the concave-convex micro-nano structure on the micro prism layer 41 is formed by imprinting, the shape and parameters of the concave-convex micro-nano structure can be changed by changing the shape of the mold. The concave-convex micro-nano structure can also be an inward concave surface or a combination of an inward concave surface and an outward convex surface, and the concave-convex micro-nano structure can also not only comprise planes with three angles, such as a quadrangular prism, a hexagonal pyramid and the like.
Cladding material 42 covers at the internal surface of little prism layer 41, and when outside light and sunshine shined into reflector layer 40, shined on cladding material 42 after the multi-angle refraction of little prism layer 41, then reflected back by cladding material 42 for reflection of light sign ability multi-angle reflection light, play the effect of sign.
Referring to fig. 3, the protective layer 30 covers the outer side of the reflective layer 40, and is a transparent injection-molded plate with a thickness of 30-50um, and is made of one of PVC (polyvinyl chloride), PET (polyethylene terephthalate), PP (polypropylene), PC (polycarbonate), or PMMA (polymethyl methacrylate), and a fluorescent agent is further added in the injection molding process, so that the protective layer 30 can also emit fluorescence, and the identification function of the reflective mark is improved. The protective layer 30 is wear-resistant, high-temperature-resistant and waterproof, and reduces the influence of external conditions on the reflective layer 40 in a fire scene.
The adhesive layer 50 covers the inner side of the reflective layer 40, is pressure-sensitive adhesive and has the thickness of 20-50um, and because the normal-temperature pressure-sensitive adhesive is adopted to replace the hot stamping 2, the influence of high temperature on the pasting effect is reduced.
The release layer 60 is a release paper and covers the inside of the adhesive layer 50.
The embodiment also provides a preparation method of the reflective mark, which is used for preparing the reflective mark and comprises the following steps:
step S1, preparing the protective layer 30 by an injection molding process, and adding a fluorescent agent into the transparent plastic particles in the injection molding process;
step S2, preparing a micro prism layer 41, coating UV paint on the inner side of the protective layer 30, and stamping a concave-convex micro-nano structure after radiation curing;
step S3, preparing a plating layer 42, and plating a layer of aluminum on the concave-convex micro-nano structure through magnetron sputtering;
step S4, preparing an adhesive layer 50, coating a pressure-sensitive adhesive layer on the inner side of the reflecting layer 40, and then baking and curing at high temperature;
step S5, covering a layer of release paper on the adhesive layer 50;
and step S6, cutting the reflective marker into an arrow shape.
When the reflective mark is adhered to the fire hose, one surface of the adhesive layer 50 is adhered to the fire hose only after the stripping layer 60 is uncovered.
The fire hose with the reflective mark provided by the embodiment guides people in a fire scene to escape through the reflecting layer 40 capable of reflecting light rays at multiple angles. The shape difference of the reflecting marks towards the two ends of the fire hose helps the personnel in the fire to confirm the direction. The brightness of the reflective mark is improved by adopting the microprism structure to replace glass beads. And hot stamping is replaced by the pressure-sensitive adhesive, so that the influence of high temperature on the pasting effect is reduced.
Second embodiment
Referring to fig. 4, a difference between the fire hose with reflective mark according to the second embodiment of the present invention and the above embodiments is that the concave-convex micro-nano structure of the micro prism layer 41' is a frustum-shaped protrusion.
