Problems solved by technology

[0004] At present, domestic back glue for walls generally has the problem that the bonding strength with the wall substrate is not strong, and it is easy to fall off.
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 preparation method of gum for a wall. The preparation method comprises the steps that an ink-receptive coating is coated on a printing paper layer; an acrylate pressure-sensitive adhesive layer is coated on a release layer; drying is performed; and the gum for the wall is obtained by compounding through a dry-type compounding technology. The preparation method is characterized in that an acrylate pressure-sensitive adhesive used by the acrylate pressure-sensitive adhesive layer is an acrylate pressure-sensitive adhesive for the wall, and is mainly made by copolymerization of a soft monomer, a hard monomer and a functional monomer, and the functional monomer at least comprises pyridine-2-acrylic acid. Pyridine-2-acrylic acid can form coordination with a Fe element in the wall to improve the adhesive force with the wall, so that the acrylate pressure-sensitive adhesive for the wall has the advantages of high adhesive strength, adsorption force, peeling strength and elongation at break, and good weather ability, and the gum for the wall obtained by taking the acrylate pressure-sensitive adhesive as the raw material can be applied to adhesion with the wall well.

Description

technical field [0001] The invention relates to a preparation method of back glue, in particular to a preparation method of back glue for walls. 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 weather resistance, UV resistance, heat resistance, water resistance, chemical resistance, transparent color, and good...
