Abstract

The invention provides flame-retardant single-sided adhesive tape. The adhesive tape comprises a basic film layer, a printing layer, an adhesive layer and an isolation layer, the basic film layer is of a flaky film-shaped structure, the printing layer is made of printing ink coated on the basic film layer, and the adhesive layer is attached to the printing layer and comprises two layers. The first layer is viscosity increasing adhesive film attached to the surface of the printing layer, the viscosity increasing adhesive film is EVA resin adhesive film containing stearic acid modified magnesium hydrate, and the mass percentage of stearic acid in stearic acid modified magnesium hydrate is 5.5-6.5%. The second layer is viscosity increasing resin containing magnesium hydrate grinding particles and coated on the surface of the first layer, the viscosity increasing resin is one of rosin resin, terpene-phenolic resin or rubber, and the particle size of the magnesium hydrate grinding particles is 500-2000 micrometers. The isolation layer is of a film-shaped structure and attached to the surface of the adhesive layer. The flame-retardant single-sided adhesive tape prepared through the corresponding method is excellent in flame retardance and high in adhesion, and tensile strength and breaking strength can be effectively improved.
