Problems solved by technology

[0005] Because the battery label is easy to burn, flame retardant treatment is required, and the traditional flame retardant film method is complicated to process and the effect is not ideal
At the same time, because the battery label is too large, it is easy to generate air bubbles, it is not easy to fit, and it is difficult to rework

Abstract

The invention provides an environment-friendly automatic-exhausting battery flame-retardant label and a preparation method thereof. The Environment-friendly automatic-exhausting battery flame-retardant label comprises a common polyester film, a fireproof coating, a waterproof printable resin layer, a flame-retardant acrylic acid pressure-sensitive adhesive layer and release backing paper. The surface of the fireproof coating is coated with the waterproof printable resin layer, the release backing paper is embossing backing paper, and after an acrylic acid pressure-sensitive adhesive is coated,latticed concave and convex points appear. The environment-friendly automatic-exhausting battery flame-retardant label has the technical effects of efficient flame retarding and automatic exhausting.

Description

technical field [0001] The invention belongs to the field of materials, and in particular relates to an environmentally friendly battery flame-retardant label with automatic exhaust and a preparation method thereof. Background technique [0002] Uniaxially oriented rigid polyvinyl chloride (PVC) film is ideal for pressure sensitive battery labels. However, due to the nature of PVC, these films are considered environmentally harmful due to the problems associated with handling PVC films. Therefore, it is desirable to obtain alternative materials. translate [0003] Publication WO2004 / 072930 discloses a shrinkable battery label comprising a polymer base film and a first pressure sensitive adhesive for bonding the label structure to the battery substrate. The polymer base film is preferably a polystyrene film and has a thickness between 0.01 and 0.05 mm. The base film is covered with a transparent polymer top film. The top film is bonded to the base film by a transparent s...
