[0003] As a new type of tape, load-bearing tape has been widely concerned in various packaging and transportation industries. At present, the base materials used in domestically produced tapes are mostly ordinary BOPP, PE, PET, and PVC. These tapes have low tensile strength and low elongation.

Abstract

The invention relates to a bearing adhesive tape which comprises an acrylic acid modified hot-melt pressure-sensitive adhesive layer and an unilateral stretching film layer, which are fixedly connected with each other; the bearing adhesive tape is high in tensile strength, and low in elongation, can bear a heaviest weight of 10 kg/cm<2>, is high in bearing performance, and low in hardness, cannot cut operators, is low in requirements on used ambient temperature, can be used at the temperature of -20-40 DEG C, and is convenient to use; the acrylic acid modified hot-melt pressure-sensitive adhesive layer is high in cohesion, adhesion force, ageing resistance, and adhesive force on a substrate, has an excellent adhesion stress on polar materials and non-polar materials, is wide in application range, contains no solvent, has no pollution to an environment, does not need to be used with a tackifying primer, is convenient to use, and reduces the use cost. A preparation method of the bearing adhesive tape is simple in process, easy to operate, high in production efficiency, high in coating precision, and high in qualified rate, and can be used for producing adhesive tapes with any widths and any lengths.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to a load-bearing adhesive tape and a preparation method thereof. Background technique [0002] Load-bearing tape is a type of tape that is attached to an object and used as a handle. [0003] As a new type of tape, load-bearing tape has been widely concerned in various packaging and transportation industries. At present, the base materials used in domestically produced tapes are mostly ordinary BOPP, PE, PET, and PVC. These tapes have low tensile strength and low elongation. Tall, not suitable for bearing heavier substances. Although the tape made of PET film with a very thick base material can meet the requirements of load-bearing tape, its hardness is high and it is easy to cut the operator, so its application is also limited accordingly. Existing adhesive tapes have higher requirements on ambient temperature, and cannot be used below 0°C, which is inconvenient to use. ...
