Problems solved by technology

[0003] 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 pressure-sensitive adhesives for walls, and has also restricted the development and application of pressure-sensitive adhesives for walls, and it is easy to cause waste of materials and unnecessary necessary economic loss

Abstract

The invention provides an anti-break acrylate pressure-sensitive adhesive for walls and a preparation method thereof. The anti-break acrylate pressure-sensitive adhesive for walls is mainly formed by copolymerization of soft monomers, hard monomers and functional monomers. The functional monomers are polytetrahydrofuryl acrylate and pyridine-2-acrylic acid. Polytetrahydrofuryl acrylate has a long carbon chain of ether linkage, which is relatively flexible and can significantly improve the tensile elongation of pressure-sensitive adhesives. Pyridine-2-acrylic acid can It forms coordination with the Fe element in the wall to enhance the adhesion with the wall. Therefore, the break-resistant acrylate pressure-sensitive adhesive for the wall has high adhesive strength, strong adsorption, good weather resistance, and peel strength. The advantages of high and high elongation at break can be well applied to the bonding with the wall.

Description

technical field [0001] The invention relates to an acrylate pressure-sensitive agent and a preparation method thereof, in particular to a break-resistant acrylate pressure-sensitive adhesive for walls and a preparation method thereof. Background technique [0002] Pressure-sensitive adhesive is an adhesive that is sensitive to pressure, does not require heating, and does not require high pressure. It can be bonded with only finger pressure. Its characteristics are that it is easy to stick, not difficult to remove, and it is not damaged when peeled off. The adhesive layer will not dry up for a long time, so the pressure-sensitive adhesive is also called self-adhesive. At present, pressure-sensitive adhesive products are widely used in various fields. Among them, 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, tra...
