Description
Technical field
The invention belongs to macromolecule adhesive technical field, more specifically, the present invention relates to a kind of transferable labels glue and preparation method thereof.
Background technology
Transferable labels is called again environment-friendly type label or labels for N time, employing transferable labels glue makes, and it can not produce vestige when tearing off, can open easily and then be bonded at above another one back of the body subsides thing above a back of the body subsides thing, label stands intact, and can repeatedly use.Current China transferable labels industry is mainly used in the industries such as daily use chemicals industry, electronic enterprises, pharmaceutical industries and logistics.
Transferable labels glue can be divided into the three major types such as hot melt adhesive pressure sensitive adhesive, water-base cement and solvent cement.Hot melt adhesive pressure sensitive adhesive is first heated by the tackiness agent of solid, carries out a kind of tackiness agent be coated with after waiting adhesive melts again, and its advantage is that mobility is strong, and viscosity is high, is applicable to low temperature labeling; The water-sol is by water-soluble for the tackiness agent a kind of tackiness agent carrying out being coated with again, belongs to acrylic tackifier, and its advantage is that stickiness is strong, and the overwhelming majority is environment-protecting asepsis, and the temperature tolerance of the water-sol, hot melt adhesive is strong simultaneously; Solvent cement is that tackiness agent dissolves and carries out a kind of tackiness agent of being coated with by medium with solvent, and its advantage is that stickiness is strong, is not easy excessive glue, high temperature resistant, adapts to outdoor labeling.Along with the proposition of environmental protection, label sticks with glue water-based pressure-sensitive adhesive that agent turns to acrylic ester emulsion to be polymerized by solvent pressure-sensitive adhesive gradually and hot-fusible pressure-sensitive adhesive prepared by synthesis block interpolymers.Relative to water-based pressure-sensitive adhesive, the unit cost of hot-fusible pressure-sensitive adhesive is cheap, excellent performance.
It is many that transferable labels is generally used for the material with polar surface; in the use procedure of transferable labels; often can find that the label of some products has wrinkling, alice, the phenomenon such as come off; sometimes even can produce the phenomenon of vestige when tearing label off, this is all relevant with the performance quality of tackiness agent.
