Problems solved by technology

[0013] 1. The mechanical properties of the self-adhesive material are poor, and it is easy to be torn or broken, resulting in damage or loss of information printed on the surface of the self-adhesive material;
[0014] 2. After the self-adhesive material is pasted, it is inconvenient to remove, and it takes a lot of effort, and it is easy to tear the self-adhesive material, resulting in damage and loss of information printed on the surface of the self-adhesive material, which cannot meet the requirements of the removable label material requirements;
[0015] 3. After the self-adhesive material is pasted and removed, a large amount of residual glue will be left on the surface of the pasted object, which will affect the appearance and use of the pasted object

Abstract

The invention discloses a self-adhesive material which is convenient to remove, which comprises a surface material layer, an adhesive layer and a release paper base material layer arranged in sequence; the surface material layer and the release paper base material layer pass through The adhesive layer is bonded and can be peeled off from each other; the surface material layer is made of the following raw materials in parts by weight: 60-70 parts of polyethylene, 30-45 parts of styrene-ethylene-propylene-styrene copolymer, 2-3.5 parts of antioxidant, 3-6 parts of flame retardant, 2-5 parts of processing aid. The easy-to-remove self-adhesive material of the present invention is easy to remove after pasting, requires little effort, is not easy to tear the self-adhesive material, and ensures the existence of information printed on the surface of the self-adhesive material. It is suitable as a removable Removable label material is used; after the self-adhesive material is pasted and removed, the amount of residual glue left on the surface of the pasted object is very small, which will not affect the appearance and use of the pasted object.

Description

technical field [0001] The invention relates to the technical field of self-adhesive materials, in particular to a self-adhesive material that is easy to remove. Background technique [0002] Self-adhesive materials are divided into five categories: [0003] 1. According to the characteristics of the adhesive, it can be divided into permanent self-adhesive materials and removable self-adhesive materials; [0004] 2. According to the classification of adhesive coating technology, it can be divided into hot-melt self-adhesive materials, solvent-based self-adhesive materials and emulsion-type self-adhesive materials; [0005] 3. According to the classification of adhesive and chemical properties, it is divided into two kinds of self-adhesive materials: rubber base and acrylic; [0006] 4. According to the characteristics of the backing paper, it is divided into three kinds of self-adhesive materials: opaque backing paper, translucent backing paper and transparent backing pape...
