Abstract

The invention discloses an easy-to-peel backing-paper-free cold laminating protective film. The adhesive tape comprises a base material layer, a release layer and an adhesive layer, wherein the two sides of the base material layer are coated with a release layer and an adhesive layer respectively. The adhesive layer is obtained by coating a glue solution on the base material layer and drying; theglue solution is prepared from the following components in parts by weight: n-butyl methacrylate, styrene, dodecyl methacrylate, acrylamide, hydroxyethyl acrylate, acrylic acid, 3,4-dimethylbenzophenone, glyceryl monocaprylate, triethylene tetramine, ethyl acetate, 4-hydroxybenzenesulfonic acid, sodium cocoyl hydroxyethyl sulfonate, diisobutyl methanol and sodium hydroxide. The cold laminating film has the advantages that the transferability is improved and no adhesive is remained during stripping; when the cold laminating film is laminated on photos, pictures and the like for a long time as aprotective layer, the cold laminating film is easy to damage or age after being used for a long time, and at this time, the protective film is convenient to replace, and does not have the problems ofadhesive residue, difficulty in stripping and the like.

Description

technical field [0001] The invention belongs to the technical field of adhesive tapes, in particular to an easy-peelable bottomless paper cold lamination protective film. Background technique [0002] Cold lamination film is a protective material that is laminated on photos and pictures by hand or automatic cold lamination machine. The traditional cold lamination film will have a layer of release paper. In the process of rolling, problems such as indentation, wrinkles, and air bubbles will occur due to the unevenness of the backing paper, and the backing paper will consume natural resources of trees and cause a load on the environment. It also increases the manufacturing cost and cleaning burden of the factory. Therefore, the cold lamination film without liner is promoted, and at the same time, the cold lamination film without liner has a good hand feeling, certain extensibility, and a wider range of use. However, the cold lamination film without liner still has the follow...
