Problems solved by technology

PE protective film is generally made of plain weave film, which is characterized by high transparency and good adhesion to the surface of the article, but the coating amount of the plain weave film is large, and it is easy to form bubbles when it is attached to the surface of the article. Wrinkles on the surface affect the appearance and use of the item

Abstract

The invention discloses a solvent-based reticulated pressure-sensitive adhesive for a polyethylene protective film and a preparation method thereof. The solvent-based reticulated pressure-sensitive adhesive comprises the following components in parts by weight: 42-45 parts of acrylate pressure-sensitive adhesive, 0.3-0.5 part of curing agent, 0.1-0.2 part of catalyst and 54-57% of solvent. The solvent-based reticulated pressure-sensitive adhesive disclosed by the invention has good adhesion to a polyethylene protective film and can realize good balance among Initial adhesion, peel strength and cohesion.

Description

technical field [0001] The invention relates to a solvent-type reticulated pressure-sensitive adhesive and a preparation method thereof, more specifically, the invention relates to a solvent-type reticulated pressure-sensitive adhesive for polyethylene protective film and a preparation method thereof. Background technique [0002] The protective film is a surface protection material used to protect the surface of an article. It is pasted on the surface of metal products, coated metal products, plastic products, automotive products, electronic products, signage products, profile products, and The surface of other products, so that it can protect the surface of the article during manufacturing, transportation, processing, storage and use, prevent the article from being polluted, scratched and slow down the oxidation of the article surface, so that the pasted article can be protected during transportation, processing, storage and use. Avoid contamination, corrosion, scratches, ...
