Description

Technical Field

[0001] The utility model relates to the technical field of adhesive tapes, in particular to a high-toughness masking tape. Background Art

[0002] Masking tape is a roll of adhesive tape made of masking paper and pressure-sensitive glue as the main raw materials. The pressure-sensitive adhesive is coated on the masking paper, and the other side is coated with anti-sticking material. It has the characteristics of high temperature resistance, good resistance to chemical solvents, high adhesion, easy to tear, soft and adherent, and no residual adhesive left after tearing. The industry generally calls it masking pressure-sensitive adhesive tape.

[0003] The Chinese patent with the authorization announcement number CN215250583U discloses a high-toughness masking tape, which relates to the technical field of paper tapes, including a base layer, a glue layer, a high-temperature resistant layer and a masking paper layer, wherein the top of the base layer is movably connected to the bottom of the glue layer, the top of the glue layer is fixedly bonded to the bottom of the high-temperature resistant layer, and the top of the high-temperature resistant layer is fixedly bonded to the bottom of the masking paper layer. According to the utility model, when the masking tape needs to be used, the masking tape and the position to be bonded can be determined first, and then the masking paper layer can be gently pressed. After the wrapping layer is squeezed, it will be broken due to the action of external force, so that the solvent flows out from the inside of the wrapping layer to the surface of the bonded object, and then the masking tape and the surface of the object are bonded, thereby avoiding the damage to the bonded object surface when the masking tape is torn due to the dislocation of the bonded object, and the waste caused by the wrong bonding of the masking tape when the masking tape is swung. At the same time, the drying of the solvent of the masking tape is slowed down, and the storage life of the masking tape is extended.

[0004] However, in the implementation of relevant technologies, it was found that the above-mentioned high-toughness masking tape design has the following problems: when the masking paper layer is gently pressed, the wrapping layer will be squeezed and ruptured due to external force, causing the solvent to flow out from the inside of the wrapping layer to the surface of the bonded object, and then the masking tape and the surface of the object are bonded, thereby avoiding the masking tape from being misaligned and damaging the surface of the bonded object when being torn. However, when the wrapping layer is ruptured, the main body will explode in all directions, affecting the contact area between the tape and the adhered object, thereby affecting the bonding effect.

In addition, in actual production, the three-dimensional dimensions of length, width and depth should be included.

[0025] Reference Figure 1 - Figure 3 , which is an embodiment of the utility model, provides a high-toughness masking tape, including a tape unit 100, a separation unit 200 and an adhesive unit 300;

[0026] The tape unit 100 includes a masking tape 101 and a wrinkle texture layer 102 matched with the masking tape 101. The wrinkle texture layer 102 is located on the outer wall of the masking tape 101 to increase friction and facilitate taking the masking tape 101.

[0027] The bonding unit 300 includes a mounting cavity 301 opened at the bottom of the masking tape 101. The number of mounting cavities 301 is several and evenly distributed. A wrapping layer 302 is fixedly installed at the top of the mounting cavity 301. Connecting blocks 303 are symmetrically installed on both sides of the mounting cavity 301. A cutting block 305 is fixedly installed at the bottom of the connecting block 303, and the cutting block 305 is located above the bottom of the wrapping layer 302. The inner cavity annular array of the mounting cavity 301 is provided with a guide groove 304, which can be used to first place the masking tape 101. After the tape 101 and the position to be bonded are determined, the masking tape 101 is gently pressed. After the masking tape 101 is squeezed, it will drive the cut piece 305 to move downward, so that the outer surface of the wrapping layer 302 is broken, and the sol flows out from the inside of the wrapping layer 302 to the surface of the bonding object, and then the masking tape 101 and the surface of the object are bonded, and the wrapping layer 302 is restricted in the installation cavity 301, which avoids the rupture of the wrapping layer 302 itself, reduces the contact area, and causes the bonding effect to decrease.

[0028] One end of the guide groove 304 is connected to the installation cavity 301, and the other end of the guide groove 304 passes through the bottom end of the masking tape 101. The sol can enter the surface of the object through the guide groove 304 to increase the bonding speed.

[0029] The separation unit 200 includes tearing openings 201 opened on opposite sides of the two sets of masking tapes 101 , and the tearing openings 201 are symmetrically arranged to facilitate tearing apart two adjacent masking tapes 101 .

[0030] The opposite surfaces of the two sets of masking tapes 101 are respectively fixedly mounted with a Velcro sub-surface sticker 202 and a Velcro mother-surface sticker 203 , and are located at the tearing opening 201 , for connecting the two masking tapes 101 .

[0031] A plastic tape 103 is disposed at the top of the masking tape 101 , and an anti-ultraviolet layer 104 is disposed at the top of the plastic tape 103 . The plastic tape 103 reinforces the edge of the masking tape 101 , and the anti-ultraviolet layer 104 is anti-ultraviolet.

[0032] A protective layer 105 is provided between the anti-ultraviolet layer 104 and the wrinkle texture layer 102 . The protective layer 105 is made of a PRF release film to prevent adhesion between the adhesive tapes.

[0033] During use, two adjacent masking tapes 101 are torn apart through the tearing mouth 201 to separate the Velcro sub-surface sticker 202 from the Velcro mother-surface sticker 203. The masking tape 101 and the position to be bonded are first determined, and then the masking tape 101 is gently pressed. After the masking tape 101 is squeezed, it will drive the cut piece 305 to move downward, causing the outer surface of the wrapping layer 302 to rupture, allowing the sol to flow out from the inside of the wrapping layer 302 to the surface of the bonding object, and then the masking tape 101 and the surface of the object are bonded. At the same time, the sol can enter the surface of the object through the guide groove 304, increasing the bonding speed. The wrapping layer 302 is confined in the installation cavity 301, which avoids the rupture of the wrapping layer 302 itself, affecting the contact area between the masking tape 101 and the object, resulting in a decrease in the bonding effect.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
