Abstract

The utility model relates to the technical field of adhesive films, and discloses an adhesive film with three layers of reinforced reinforcing belts, which comprises a protective layer, wherein a PTU layer is arranged at the bottom of the protective layer, a glue layer is arranged at the bottom of the PTU layer, transverse fiber yarns and longitudinal fiber yarns are arranged in the PTU layer, and the transverse fiber yarns and the longitudinal fiber yarns are distributed in the PTU layer in a staggered manner. This use three-layer reinforcing belt glued membrane is equipped with horizontal cellosilk and vertical cellosilk through PTU in situ, and horizontal cellosilk and vertical cellosilk crisscross distribution in PTU in situ form network structure, promote whole glued membrane tear resistance and tensile strength, but dispersed stress and promote tear resistance, avoid the interlayer fracture that local stress concentration led to, solved traditional glued membrane mechanical properties not enough, the interlayer combine weak, fibre utilization ratio is low and high temperature stability subalternation problem.

Description

Use three-layer reinforcing to strengthen area glued membrane Technical Field The utility model relates to the technical field of adhesive films, in particular to an adhesive film with three layers of reinforced belts. Background Along with the increase of the demand of the clothing field for high-performance adhesive films, the traditional multilayer adhesive films (such as a protective layer-PTU layer-adhesive layer structure) gradually expose the following technical bottlenecks in the aspects of mechanical properties, functional integration, environmental suitability and the like: Conventional adhesive films (such as single TPU or common composite materials) are difficult to meet the extreme working condition requirements due to the limitation of a material system and tear resistance and tensile strength. For example, under dynamic loading or high stress environment, the adhesive film is easy to cause local tearing due to stress concentration, so that the adhesive film is totally failed. In the prior art, although the strength is attempted to be improved by adding inorganic filler (such as nano ceramic) or thickening a matrix, embrittlement or flexibility reduction of the material is easy to be caused, and the strength and the ductility are difficult to be combined. Disclosure of utility model The present utility model is directed to providing a method for applying a three-layer reinforced adhesive tape film to solve the above-mentioned problems in the prior art. In order to achieve the purpose, the technical scheme is that the three-layer reinforced adhesive film comprises a protective layer, wherein a PTU layer is arranged at the bottom of the protective layer, a glue layer is arranged at the bottom of the PTU layer, transverse fiber yarns and longitudinal fiber yarns are arranged in the PTU layer, and the transverse fiber yarns and the longitudinal fiber yarns are distributed in the PTU layer in a staggered manner. As a further improvement of the utility model, the transverse fiber filaments and the longitudinal fiber filaments are provided in a plurality, and the transverse fiber filaments and the longitudinal fiber filaments are uniformly distributed in the PTU layer. As a further improvement of the utility model, the PTU layer is opened and closed with a connecting channel, and the connecting channel communicates the bottom of the protective layer with the top of the glue layer. As a further improvement of the utility model, the top of the connecting channel is provided with a circular groove, and the diameter value of the circular groove is larger than that of the connecting channel. As a further improvement of the utility model, the two sides of the inner cavity of the connecting channel are provided with barb grooves, and a plurality of barb grooves are arranged. Compared with the prior art, the utility model has the beneficial effects that: 1. This use three-layer reinforcing belt glued membrane is equipped with horizontal cellosilk and vertical cellosilk through PTU in situ, and horizontal cellosilk and vertical cellosilk crisscross distribution in PTU in situ form network structure, promote whole glued membrane tear resistance and tensile strength, but dispersed stress and promote tear resistance, avoid the interlayer fracture that local stress concentration led to, solved traditional glued membrane mechanical properties not enough, the interlayer combine weak, fibre utilization ratio is low and high temperature stability subalternation problem. 2. This use three-layer reinforcing belt glued membrane has offered the connecting channel on through the PTU layer, and the connecting channel communicates protective layer and glue layer respectively, is convenient for pour into the glue layer into the connecting channel in, has improved glue layer respectively with PTU layer and protective layer joint strength, makes clothing surface fabric stronger fastness, uses the connection in clothing juncture, replaces sewing technology, is applied to sportswear, jacket, suit and western-style clothes.
