[0028] In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more than two. In addition, the terms "first", "second" are only used to distinguish in the description, and have no special meaning.

[0029] In one embodiment of the present utility model, as shown in Figures 1-5 A markable fluorescent adhesive tape is provided, comprising: a reel 1 and an adhesive tape body 2. The adhesive tape body 2 is spirally attached to the outer periphery of the reel 1, and the adhesive tape body 2 is composed of a protective outer layer 3, a thermal buffer layer 4, a thermal induction layer 5, a fluorescent enhancement layer 6 and an adhesive layer 7, and the adhesive tape body 2 is used for marking and emitting fluorescence.

[0030] The present utility model provides a fluorescent adhesive tape easy to mark, which protects the internal structure through the protective outer layer 3, maintains the integrity of the appearance and the stability of the function of the adhesive tape; through the thermal buffer layer 4, the influence of the environmental temperature can be avoided, and the accidental touch of other heat sources can be prevented; through the thermal induction layer 5, the heat transmitted by hand pressing can be sensed, and when the heat temperature reaches the triggering temperature interval of the thermal induction layer 5, color development can be achieved; through the fluorescent enhancement layer 6, the thermal induction layer 5 is cooperated with the thermal induction layer 5, and the fluorescent enhancement layer 6 is excited synchronously when the thermal induction layer 5 develops color, so that the mark can be highlighted in strong light or dark light environment, and the visibility and the recognition degree of the mark are strengthened; through the adhesive layer 7, the adhesive tape can be pasted with various materials.

[0031] Under normal conditions, the fluorescent enhancement layer 6 can emit fluorescence in bright and dark states, but the fluorescence is not obvious in bright state and is obvious in dark state, but when the thermal induction layer 5 is cooperated, the fluorescence emission of the fluorescent enhancement layer 6 is enhanced after the thermal induction layer 5 develops color.

[0032] Preferably, the protective outer layer 3 can be selected from a biaxially stretched polyimide film, and further, the surface of the protective outer layer 3 can be coated with an anti-reflection coating, the anti-reflection coating can adopt a nano-sized magnesium fluoride material, the optical transmittance is enhanced, the color development mark of the thermal induction layer 5 is better observed, and the fluorescence observation clarity is improved.

[0033] Preferably, the surface of the protective outer layer 3 is plated with an anti-ultraviolet coating 8, and the anti-ultraviolet coating 8 is used to enhance the anti-ultraviolet ability.

[0034] Preferably, the heat-sensitive layer 5 can be based on a thermochromic liquid crystal copolymer, with the addition of a thermoplastic polyurethane to extend the color development time, silica nanoparticles to improve color stability, and rare earth europium complexes to enhance color sensitivity and fluorescence performance. During marking, the temperature of the adhesive tape body 2 can be raised by repeatedly pressing and rubbing with the hand, causing the heat-sensitive layer 5 to change color reversibly from transparent colorless to bright orange-red.

[0035] Specifically, the fluorescence enhancement layer 6 can use quantum dot fluorescent materials such as cadmium sulfide / cadmium selenide core-shell structures, uniformly dispersed in a transparent epoxy resin matrix. The quantum dots are specially surface-modified to improve stability and fluorescence efficiency, and are adapted to the color-changing temperature of the heat-sensitive layer 5. They emit bright green fluorescence and form a sharp contrast with the red color of the heat-sensitive layer 5 after color development, improving the visibility of the marking.

[0036] Preferably, the adhesive layer 7 can be based on silicone-modified acrylate copolymer with the addition of nano-aluminum oxide to enhance cohesive strength and heat resistance.

[0037] Preferably, the heat buffer layer 4 includes a heat-insulating inner layer 9, a heat-conducting flexible middle layer 10, and an elastic outer layer 11. The heat-insulating inner layer 9 is used to block external temperature, the heat-conducting flexible middle layer 10 is used to disperse local heat and buffer external force, and the elastic outer layer 11 is used to assist in heat insulation and protect the inside. Specifically, the heat-insulating inner layer 9 is 2.5-3.5 mm, the heat-conducting flexible middle layer 10 is 0.8-1.2 mm, and the elastic outer layer 11 is 0.6-1.0 mm.

[0038] By setting the heat-insulating inner layer 9, the heat-conducting flexible middle layer 10, and the elastic outer layer 11, a "sandwich" three-layer structure is constructed. It effectively blocks the heat of the environment, stabilizes the base temperature of the heat-sensitive layer 5, and ensures that the heat-sensitive layer 5 can only develop color when pressed by the hand, avoiding false triggering.

[0039] Specifically, the heat-insulating inner layer 9 can be a 2.5 mm thick aerogel felt that effectively blocks the heat of the external environment, so that the adhesive tape can only develop color when it receives enough heat from the hand pressing, and will not produce false markings due to small fluctuations in internal temperature.

[0040] Further, the heat-conducting flexible middle layer body 10 can be a 0.8mm thick flexible graphite sheet, preventing local overheating from triggering false color development. In the use scenarios of the tape, various heat disturbances may be encountered. When the tape body 2 is close to some heat sources, or under direct sunlight, the local temperature may rise. The graphite sheet can disperse heat, preventing the heat-sensitive layer 5 from triggering color development due to local overheating, which may produce false markings, ensuring that color development only occurs when needed (e.g. when the hand is pressed). The graphite sheet ensures that the heat-sensitive layer 5 is uniformly heated, and when color development is triggered by hand pressing, the graphite sheet can evenly distribute the heat generated by hand pressing to the heat-sensitive layer 5 below, allowing the entire heat-sensitive layer 5 to develop color synchronously at the triggering temperature, ensuring the quality and consistency of the markings.

[0041] Further, the elastic outer layer body 11 is a 0.6mm thick thermoplastic polyurethane elastomer, which has elasticity, wear resistance and aging resistance, and can assist in heat insulation and protection of the interior.

[0042] The easy-to-mark fluorescent tape also includes an anti-sticking coating on the outer surface of the roll 1. The anti-sticking coating prevents the tape body 2 from sticking to the roll 1. The anti-sticking coating can be a silicone coating, which prevents the tape body 2 from sticking to the roll 1 when in contact for a long time, without affecting the friction between the tape and the roll 1.

[0043] The easy-to-mark fluorescent tape also includes a cutting tool 12 on the roll 1. The cutting tool 12 is used to cut the tape body 2, making it easy for users to cut the tape body 2 from the roll 1, and also allowing users to obtain the appropriate length of the tape body 2 for marking according to actual needs.

[0044] Specifically, the surface of the cutting tool body of the cutting tool 12 is provided with a hardening layer 13, which is used to improve the surface hardness of the cutting tool body. The cutting tool 12 can be made of plastic, and the surface of the cutting tool body of the cutting tool 12 can be coated to improve its wear resistance and corrosion resistance. For example, titanium nitride can be used as the hardening layer 13.

In the use process of the adhesive tape reel 1, various external forces may be acted, such as bumping in the carrying process, pulling in use and the like. The close cooperation of the limiting block 17 and the clamping slot 18 can effectively prevent the cutting tool 12 from shaking or shifting in the installation slot 16.

[0048] The limiting block 17 in the installation slot 16 can be integrally formed with the reel 1.

[0049] Preferably, the installation slot 16 can be a closed ring, and the shape of the cutting tool 12 is matched with the shape of the installation slot 16. When the limiting block 17 and the clamping slot 18 are not arranged, the cutting tool 12 can be directly clamped into the installation slot 16, and the flexibility of the cutting tool 12 is facilitated.
