DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0020] See also Figure 1-3 A high-temperature resistant Mara tape in this embodiment includes a tape body 1 and a reel 2. A heat-resistant component 11 is provided on the tape body 1. The heat-resistant component 11 includes an anti-stretching layer 12, a high-temperature resistant layer 13, a flame retardant layer 14, and an anti-aging layer 15, and the four are distributed in sequence from the inside to the outside. At least two positioning grooves 10 are provided at the end of the reel 2, and a positioning block 8 is provided in the positioning groove 10. A rubber sleeve 7 is provided on the positioning block 8 and abuts against the positioning groove 10.
[0021] During actual use, the Mara tape can effectively withstand high temperatures under the action of the heat-resistant component 11 to prevent the tape from deforming or melting. Under the action of the heat-resistant component 11, the tape will not deform. At the same time, after the tape is cut, the positioning block 8 can be placed in the positioning groove 10 near the torn end of the tape to indicate the torn end of the tape, making it more convenient to find the torn end of the tape.
[0022] Furthermore, the anti-stretching layer 12 is a nylon film layer, and the high temperature resistant layer 13 is a polytetrafluoroethylene layer.
[0023] Furthermore, the flame retardant layer 14 is a halogen-free flame retardant PC film, and the anti-aging layer 15 is an acrylic rubber layer.
[0024] It should be noted that the heat-resistant component 11 composed of the anti-stretching layer 12, the high-temperature resistant layer 13, the flame-retardant layer 14, and the anti-aging layer 15 can effectively improve the high-temperature resistance of the tape body 1; the anti-aging layer 15 is composed of acrylic rubber, which can make the tape body 1 have good UV resistance and anti-aging properties, effectively prevent the tape body 1 from aging, thereby increasing the service life of the tape body 1; the high-temperature resistant layer 13 is composed of a polytetrafluoroethylene layer, which has excellent heat and cold resistance, and can be used at a working temperature of 250 degrees Celsius, so that the tape body 1 has good high-temperature resistance, thereby avoiding the tape from being damaged by In the case of deformation due to high temperature, the stretch-resistant layer 12 is composed of a nylon film layer. The nylon film layer has high tensile strength and tensile strength, and also has good heat resistance. The nylon film layer further enhances the high temperature resistance of the tape body 1, and improves its stretch resistance, thereby reducing the possibility of deformation of the tape body 1, thereby making it more convenient to find the tearing end of the tape. The flame-retardant layer 14 is composed of a halogen-free flame-retardant PC film. The halogen-free flame-retardant PC film gives the tape body 1 a flame-retardant effect and improves the functionality of the tape. The halogen-free flame-retardant PC film has excellent flame-retardant properties, can effectively suppress the spread of flames, and reduce the risk of fire occurrence and spread.
[0025] Furthermore, at least two positioning grooves 10 are equidistantly distributed on the reel 2 in a circumferential manner.
[0026] Specifically, after the adhesive tape body 1 is cut, by placing the positioning block 8 in the positioning groove 10 closest to the torn end of the adhesive tape, the position of the torn end of the adhesive tape can be indicated for the next use of the adhesive tape.
[0027] In a specific embodiment, the tape body 1 is fixed on the reel 2 , the positioning groove 10 is provided at the top of the reel 2 , and the heat-resistant component 11 is fixed on the outer side of the tape body 1 .
[0028] See also Figure 3In this embodiment, a groove 9 is provided in the reel 2, an inner ring block 4 is provided in the groove 9, at least two support blocks 5 are provided in the inner ring block 4, and the same connecting block 3 is provided on the side of at least two support blocks 5 away from the inner ring block 4, and an articulated seat 6 is provided on the connecting block 3 corresponding to the positioning block 8, and the positioning block 8 is arranged in the articulated seat 6.
[0029] During actual use, the connection block 3 is held by hand, and the positioning block 8 is separated from the positioning groove 10. As the adhesive tape is used, the connection block 3 can be held by hand to allow the adhesive tape to rotate, thereby making the adhesive tape more convenient to use.
[0030] Furthermore, the positioning block 8 performs a circular motion with the hinge seat 6 as the center.
[0031] It can be understood that after the positioning block 8 is connected to the positioning groove 10, the torn end of the tape can be indicated, and the connecting block 3 and the inner ring block 4 can be locked at the same time. When the positioning block 8 and the positioning groove 10 are connected, the rubber sleeve 7 can make the connection tighter.
[0032] Furthermore, the inner ring block 4 is rotatably connected inside the groove 9 .
[0033] Specifically, when using the tape, hold the connecting block 3, and the connecting block 3 rotates under the action of the inner ring block 4, so that the tape can be rotated when used, without manually pushing the tape to rotate, making it more convenient to use. Under the action of the connecting block 3, the supporting block 5 and the inner ring block 4, the chance of deformation of the tape can also be avoided.
[0034] The working principle of the above embodiment is:
[0035] (1) When the Mara tape is in use, under the action of the heat-resistant component 11, it can effectively withstand high temperatures to prevent the tape from being deformed or melted. The heat-resistant component 11, which is composed of the anti-stretching layer 12, the high-temperature resistant layer 13, the flame-retardant layer 14, and the anti-aging layer 15, can effectively improve the high-temperature resistance of the tape body 1; the anti-aging layer 15 is composed of acrylic rubber, which can make the tape body 1 have good UV resistance and anti-aging properties, effectively preventing the tape body 1 from aging, thereby increasing the service life of the tape body 1; the high-temperature resistant layer 13 is composed of a polytetrafluoroethylene layer, which has excellent heat and cold resistance and can be used at a working temperature of up to 250 degrees Celsius, so it is The tape body 1 has good high temperature resistance to avoid deformation of the tape due to high temperature. The anti-stretching layer 12 is composed of a nylon film layer. The nylon film layer has high tensile strength and tensile strength, and also has good heat resistance. The nylon film layer further improves the high temperature resistance of the tape body 1 and improves its tensile resistance, reducing the possibility of deformation of the tape body 1, thereby making it more convenient to find the tearing end of the tape. The flame retardant layer 14 is composed of a halogen-free flame retardant PC film. The halogen-free flame retardant PC film gives the tape body 1 a flame retardant effect and improves the functionality of the tape. The halogen-free flame retardant PC film has excellent flame retardant properties, can effectively suppress the spread of flames, and reduce the risk of fire occurrence and spread.
[0036] (2) During the use of the tape, the tear end of the tape can be found quickly and easily according to the indication of the positioning block 8. After finding the tear end of the tape, the positioning block 8 is rotated to separate it from the positioning groove 10 close to the tear end of the tape. The tape can be used by holding the connecting block 3. When holding the connecting block 3, the tape will rotate synchronously with the inner ring block 4. There is no need to manually push the tape to rotate, making the tape more convenient to use.
