Problems solved by technology

[0004] At present, domestic pressure-sensitive adhesives for walls generally have problems such as low bonding strength between the pressure-sensitive adhesive and the wall substrate, easy to fall off, and easy to break during stretching.
The existence of such problems has brought great inconvenience to the application of back glue for the wall, and has also restricted the development and application of the back glue for the wall, and it is easy to cause waste of materials and unnecessary waste in practical applications. Economic losses

Abstract

The invention relates to a method for preparing anti-breakage gum for a wall. The method comprises the following steps: coating a printing paper layer with an ink absorption coating, coating a release layer with an anti-breakage acrylate pressure sensitive adhesive layer, drying, and compounding, thereby obtaining the anti-breakage gum for the wall, wherein the anti-breakage acrylate pressure sensitive adhesive used in the anti-breakage acrylate pressure sensitive adhesive layer refers to an anti-breakage acrylate pressure sensitive adhesive for the wall and is mainly formed by copolymerization of a soft monomer, a hard monomer and functional monomers; the functional monomers refer to polytetrahydrofuran acrylate and pyridine-2-acrylic acid; the polytetrahydrofuran acrylate has a long carbon chain of ether bonds and is high in flexibility, and the tensile elongation of the pressure sensitive adhesive can be obviously improve; and the pyridine-2-acrylic acid can form coordination with Fe element in the wall, and the adhesive force with the wall is enhanced. Therefore, the anti-breakage gum for the wall has the advantages of high adhesive strength, high adsorption force, high weather resistance, high peel strength and high elongation at break and can be well applied to adhesion with the wall.

Description

technical field [0001] The invention relates to a method for preparing an anti-fracture adhesive for walls, in particular to a method for preparing acrylate pressure-sensitive adhesives and reducing solvent residues in acrylate pressure-sensitive adhesives. Background technique [0002] As a form of mass media, print advertisements have been pervasive in every aspect of life. Among them, the carrier of print advertisements—adhesive, also called self-adhesive label printing materials, is a kind of advertising consumables used in the field of digital printing made of paper, plastic film, glue and release paper. The front can be spray-painted, and the back has glue, which can be pasted on display boards, walls, and KT boards. [0003] The key material in the adhesive is the choice of the glue used, that is, the pressure-sensitive adhesive used in it. Acrylate pressure-sensitive adhesives are a large category of pressure-sensitive adhesives. Their polymers have excellent weath...
