Technical Field
[0001] This invention relates to the technical field of emergency lighting, and more specifically, to a method for applying luminescent coating to emergency tunnel passages. Background Technology
[0002] In the event of an emergency inside the tunnel, passengers can evacuate to the opposite lane or escape route via the tunnel's emergency exit, which can better help those stranded inside the tunnel to evacuate in a timely manner.
[0003] After long-term operation, the fireproof coating of the tunnel emergency passage has peeled off and corroded. In addition, the original coating does not have a self-luminous effect after the tunnel loses power, which will be detrimental to emergency evacuation in the event of an emergency.
[0004] In existing technologies, in emergency situations such as fires or tunnel power outages, there are problems with the lack of lighting or insufficient brightness and uniformity of lighting in tunnel emergency passages, which affect the safety of escape. To solve the above problems, emergency lights are generally installed in tunnel emergency passages. However, due to the humid environment in the tunnel, emergency lights are prone to dust accumulation, aging, and may fall off the wall. In addition, when the power is off, the brightness of emergency lights is insufficient, the uniformity of illumination is poor, and the duration is short. Summary of the Invention

Then, two coats of luminescent material undercoat are applied to the primer layer, and the layer is left to stand for a set time until it dries. Finally, two coats of luminescent material topcoat are applied to the undercoat layer.
[0015] Optionally, in construction step 3), before applying the luminescent material primer, the luminescent material primer is stirred evenly using a hand-held electric mixer; before applying the luminescent material undercoat, the luminescent material undercoat is stirred evenly using a hand-held electric mixer; before applying the luminescent material topcoat, the luminescent material topcoat is stirred evenly using a hand-held electric mixer.

The multiple stirring strips are arranged at intervals along the circumference of the rotating shaft. The upper end of the stirring strip is connected to the rotating shaft, and the lower end of the stirring strip is bent downward off the rotating shaft and connected to the rotating ring.
[0018] The machine body is equipped with a motor that drives the rotating shaft to rotate and a controller. The motor and the controller are electrically connected. The machine body is equipped with control buttons, which are used to control the motor drive.
[0019] Optionally, before the primer for the luminescent material is stirred evenly using a handheld electric mixer, the luminescent device is wrapped with a protective film to prevent the primer, the undercoat, and the topcoat from splashing onto the outer surface of the luminescent device during the stirring process; after the construction is completed, the protective film is removed.

For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.
[0034] Reference Figure 1-4 The image shows a preferred embodiment of the present invention.
[0035] The method for applying luminescent coating to emergency tunnel passages provided by this invention includes the following construction steps:
[0036] 1) The tunnel emergency passage is formed on both sides of the tunnel. The outer side of the tunnel emergency passage has an enclosure wall 101, on which light-emitting devices 110 are installed. The bottom of the tunnel emergency passage has a bottom wall 102 for pedestrians to walk on. The surface of the enclosure wall 101 has a fireproof coating, and the inside of the enclosure wall 101 has a concrete surface. The fireproof coating is removed using cleaning equipment to expose the concrete surface.
[0037] 2) Level the concrete surface with cement mortar to form a mortar layer that covers the entire concrete surface; then apply putty over the mortar layer to form a putty layer that covers the entire mortar layer.
[0038] 3) Apply a luminescent material primer to the putty layer to form a primer layer, which completely covers the putty layer; apply a luminescent material undercoat to the primer layer to form a lower layer, which completely covers the primer layer; apply a luminescent material topcoat to the lower layer to form a top layer, which completely covers the lower layer.
[0039] The above-mentioned method for applying luminescent coating to tunnel emergency passages involves illuminating the upper layer with light through the luminescent device 110. The light energy is stored in the upper layer, lower layer, and primer layer. In case of an emergency, when the luminescent device 110 fails, the entire wall surface emits light, which is uniform and lasts for a long time, ensuring effective illumination and improving the safety of emergency evacuation.
[0040] Specifically, the primer layer is white and is used to improve the brightness of the light and the adhesion of the luminescent coating to the substrate.
[0041] The luminescent material primer, luminescent material undercoat, and luminescent material topcoat are mainly prepared using rare earth and nanomaterials through a formula. They can be Zhongyi Sunshine's multifunctional energy storage luminescent coating, which has multiple functions such as fire resistance and non-combustibility, brightening and gloss enhancement, delayed luminescence, stain resistance, corrosion resistance, acid and alkali resistance, self-cleaning, antibacterial and mildew prevention, antistatic properties, no sparks generated by heavy object impact, release of negative oxygen ions, increased smoke penetration and visibility, non-toxic, harmless and environmentally friendly, and long service life. It is a green building material with no restrictions on its application scope.
[0042] In step 1), after the fireproof coating is removed using cleaning equipment, multiple cracks are found on the concrete surface. These cracks are then repaired and filled. Since a pneumatic impact drill is used to scrape off the fireproof coating quickly and completely, concrete should be used to repair the cracks to ensure the smoothness and adhesion of the primer layer.
[0043] In step 2), before applying cement mortar to the concrete surface for leveling, the concrete surface is cleaned using a cleaning tool. After the concrete surface dries, cement mortar is applied for leveling. Applying cement mortar makes the surface of the work surface smooth, ensuring that various coatings can adhere evenly in subsequent processes.
[0044] Specifically, in step 3), a primer, a lower luminescent material, and an upper luminescent material are applied by brushing; the amount of primer used is 0.4 kg / m². 2 ~0.45kg / m 2 The amount of luminescent material used in the fabric is 0.3 kg / m². 2 ~0.35kg / m 2 The amount of luminescent material used on the top layer is 0.1 kg / m². 2 ~0.15kg / m 2 .
[0045] In step 3), two coats of luminescent material primer are applied to the putty layer using a brush to form a primer layer; two coats of luminescent material undercoat are applied to the primer layer using a brush to form a lower layer; and two coats of luminescent material topcoat are applied to the lower layer using a brush to form a upper layer. This two-coat application ensures uniform coating and consistent luminous brightness.
[0046] In step 3), after applying two coats of luminescent material primer to the putty layer, allow it to stand for a set time until the primer layer is dry. Then, apply two coats of luminescent material undercoat to the primer layer, allow it to stand for a set time until the undercoat layer is dry, and then apply two coats of luminescent material topcoat to the undercoat layer. This avoids mixing and reaction between the coating layers, which could significantly reduce the luminescent effect and cause uneven luminescence intensity.
[0047] In construction step 3), before applying the luminescent material primer, the luminescent material primer is stirred evenly using a hand-held electric mixer; before applying the luminescent material undercoat, the luminescent material undercoat is stirred evenly using a hand-held electric mixer; before applying the luminescent material topcoat, the luminescent material topcoat is stirred evenly using a hand-held electric mixer.
[0048] The handheld electric mixer includes a body with handles on both sides for workers to hold. The lower end of the body has a rotating shaft 210 extending vertically downwards. A horizontally arranged connecting shaft 211 is fixedly connected to the lower end of the rotating shaft 210. The middle part of the connecting shaft 211 is fixedly connected to the rotating shaft 210. A horizontally arranged rotating ring 212 is provided on the outer periphery of the connecting shaft 211. The two ends of the connecting shaft 211 are respectively fixedly connected to the inner periphery of the rotating ring 212.
[0049] Multiple stirring strips 213 are connected to the outer periphery of the lower part of the rotating shaft 210. The multiple stirring strips 213 are arranged at intervals along the circumference of the rotating shaft 210. The upper end of the stirring strip 213 is connected to the rotating shaft 210, and the lower end of the stirring strip 213 is bent downward off the rotating shaft 210 and connected to the rotating ring 212.
[0050] The machine body contains a motor that drives the rotating shaft 210 to rotate and a controller. The motor and controller are electrically connected, and the machine body is equipped with control buttons to control the motor drive. In this way, after the motor drives the rotating shaft 210 to rotate, it drives the rotating ring 212 and the stirring bar 213 to rotate. Since the stirring bar 213 is bent and extended in multiple ways, it greatly increases the stirring area during rotation, ensuring uniform stirring.
[0051] Before thoroughly mixing the primer for the luminescent material using a handheld electric mixer, wrap the luminescent device 110 with a protective film to prevent the primer, undercoat, and topcoat of the luminescent material from splashing onto the outer surface of the luminescent device 110 during the mixing process. After the application is complete, remove the protective film. This prevents paint from splashing onto the luminescent device 110 during mixing, which would otherwise be difficult to clean.
[0052] In this embodiment, in construction step 3), the luminescent material primer, the luminescent material undercoat, and the luminescent material topcoat are respectively installed in an independent stirring drum 300; the stirring drum 300 has a liquid storage chamber that extends through the top of the stirring drum 300 and forms a top opening at the top of the stirring drum 300; the bottom of the liquid storage chamber has two downward-facing recessed embedding holes 301; and the two handles are respectively provided with downward-facing screw holes.
[0053] A positioning pin 220 is connected to the handle. The upper end of the positioning pin 220 has a threaded section that mates with a screw hole, and the lower end of the positioning pin 220 has an inserting section that is embedded in the inserting hole 301. The threaded section is screwed into the screw hole to fix the positioning pin 220 to the machine body. The positioning pin 220 and the rotating shaft 210 are arranged in parallel.
[0054] In construction step 3), when the rotating shaft 210 is placed in the mixing drum 300 and the embedded section is movably positioned in the embedded hole 301, there is a rotational gap between the rotating ring 212 and the bottom of the liquid outlet chamber. The motor is controlled by the control button to drive the rotating shaft 210 to rotate. In this way, during the mixing process of the hand-held electric mixer, the stirring bar is prone to touching the drum wall, causing panic among the construction personnel, and ultimately resulting in a large amount of paint liquid splashing. The construction personnel need to be very careful. The above-mentioned design of the positioning column 220 allows the positioning column 220 to be embedded in the embedded hole 301 before starting the motor to drive the rotating shaft 210 to rotate. At the same time, this can relatively press and fix the mixing drum 300, which is more labor-saving and avoids displacement of the mixing drum 300.
[0055] In this embodiment, the bottom of the embedding hole 301 is provided with an upwardly protruding elastic body 310, and the bottom of the elastic body 310 is fixedly connected to the bottom of the embedding hole 301; the bottom of the embedding section has a downwardly arranged abutment surface, and the abutment surface is recessed upward to form a positioning hole 221; the outer periphery of the embedding section has a plurality of elastic rings 320, the plurality of elastic rings 320 are arranged at intervals along the axial direction of the embedding section, and the elastic rings 320 are arranged around the circumference of the embedding section.
[0056] In construction step 3), after the embedded section is movably embedded in the embedded hole 301, the elastic body 310 is movably embedded from bottom to top into the positioning hole 221, the elastic ring 320 is placed in the embedded hole 301, and the elastic ring 320 abuts against the inner sidewall of the embedded hole 301.
[0057] As the rotating shaft 210 rotates, manually pressing the handle drives the machine body to move up and down elastically. During this up-and-down elastic movement, the elastic body 310 also moves up and down elastically. As the elastic body 310 moves up and down, the elastic ring 320 deforms elastically, causing the machine body to move horizontally elastically. Elastic positioning is achieved through the cooperation between the elastic body 310 and the positioning hole 221. When the operator presses on the elastic body 310, they can feel the elastic buffering force, confirming successful positioning. Simultaneously, during the up-and-down movement of the elastic body 310, a slight oblique driving force causes the elastic ring 320 to deform elastically within the insertion hole 301, causing the machine body to swing slightly left and right. The well-designed dimensions effectively prevent collisions while still allowing for wide-range mixing.
[0058] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
