Magneto-thermal visbreaking type double faced adhesive tape

Abstract

A magneto-thermal visbreaking type double faced adhesive tape comprises a base film, adhesive layers are arranged on the front face and the back face of the base film respectively, and release films are arranged on the outer sides of the two adhesive layers respectively. The adhesive layer comprises heat-reducing adhesive and ultraviolet-cured resin, magnetic particles capable of generating heat under the action of an alternating magnetic field are mixed in the ultraviolet-cured resin, the particle size of the magnetic particles is 100-200nm, and the magnetic particles account for 20%-30% of the total mass of the ultraviolet-cured resin and the magnetic particles. The magnetic particles in the ultraviolet curing resin 4 generate heat through a small alternating magnetic field generator under the conditions of no heating and no UV irradiation, the heat is transferred from the ultraviolet curing resin 4 to the thermal visbreaking adhesive 3, and the thermal expansion microspheres in thethermal visbreaking adhesive 3 are heated and expanded, so that a gap is generated between the adhesive and a bonded object, and the bonding area is reduced, so that the viscosity reduction effect isachieved. After an object is pasted, no glue mark is left on the surface of the object, and the surface of the bonded object is not damaged.

Description

technical field [0001] The invention relates to a double-sided adhesive tape. Background technique [0002] In recent years, ordinary adhesive tape and double-sided adhesive tape have become common items in daily life. No matter it is an ordinary family or a company, they will use them as the best choice for quickly pasting items, which promotes the introduction of such easy-to-paste products on the market. There are a wide variety of things in eyes, and the more they are made, the more diversified they are for consumers to choose according to their own needs. However, the current double-sided adhesive tape is prone to residue after pasting the articles, pollutes or even damages the pasted articles. If there can be a colloid that can reduce viscosity and have no glue residue when peeling off, this type of problem can be solved. [0003] At present, the adhesives on the market are mainly heat-reducing adhesives and UV adhesives. When they are used as double-sided adhesives,...

AI Technical Summary

Problems solved by technology

[0003] At present, the adhesives on the market are mainly heat-reducing adhesives and UV adhesives. When they are used as double-sided adhesives, since the adhered items are opaque and the adhered items cannot be removed and heated, it is difficult to reduce the viscosity. Glue has been greatly restricted in the application of double-sided tape
