Problems solved by technology

Among them, the foam tape is made of a special glue and glue, which has good adhesion at room temperature. After heating to a suitable temperature, the glue surface expands and sticks to the urban area. It is used for fixing and protecting parts in the electronic industry. , to avoid scratches and damage to products in processing engineering, application number: CN 201610763090.9 Although it discloses a foam tape with a high removal rate that is easy to detach, which improves the sticky adhesion and can also improve the regularity of curling, but the foam tape The foaming effect is poor, so that when the temperature rises, the viscosity decay is still slow, and due to the material problem of the foam tape itself, the foam tape is easy to resist peeling when it is easily attacked by acid and alkali or water from the outside world. , for this reason, it is necessary to develop and improve

Abstract

The invention discloses an easily-released and high-removal-rate foam adhesive tape. The easily-released and high-removal-rate foam adhesive tape comprises an adhesive tape base layer, an upper adhesive film layer and a lower adhesive film layer, wherein the upper adhesive film layer and the lower adhesive film layer are arranged on the upper surface and the lower surface of the adhesive tape baselayer respectively, above the upper adhesive film layer is coated with a protective layer, and under the lower adhesive film layer is stuck with a foam layer. The foam layer, the lower adhesive filmlayer and the adhesive tape base layer are provided with a plurality of spot through holes distributed in a matrix and communicated with one another and are then hot pressed. By means of the spot through holes, after the easily-released and high-removal-rate foam adhesive tape is heated, heat can infiltrate more easily via the spot through hole to accelerate the heating speed as well as the viscosity reduction speed, so that eh inside of the easily-released and high-removal-rate foam adhesive tape can be more thorough in foaming.

Description

technical field [0001] The invention relates to the technical field of adhesive tapes, in particular to a foam adhesive tape that is easy to detach and has a high removal rate. Background technique [0002] Adhesive tape is composed of two parts, base material and adhesive, and two or more unconnected objects are connected together by bonding. Its surface is coated with a layer of adhesive. The earliest adhesives came from animals and plants. In the nineteenth century, rubber was the main component of adhesives; in modern times, various polymers are widely used. Adhesives can stick to things because of the formation of bonds between their own molecules and the molecules of the objects to be connected, and this bond can firmly bind the molecules together. The composition of the adhesive has various polymers according to different brands and types. Among them, the foam tape is made of a special glue and glue, which has good adhesion at room temperature. After heating to a s...
