Abstract

The invention discloses a fog-resistant aqueous pressure-sensitive adhesive for a polyethylene protection film. The adhesive is prepared by using the manner of seeded emulsion polymerization. According to the invention, seeded emulsion is prepared at first, then pre-emulsion is added into the seeded emulsion drop by drop, the seeded emulsion and the pre-emulsion fully react by replenishing an initiator, cooling and pH value adjusting are carried out, and a discharged material is filtered. The invention also provides a polyethylene protection film containing the fog-resistant aqueous pressure-sensitive adhesive and a preparation method thereof. Through adjusting utilization amount of a cross-linking agent and gelatinizing content, an appropriate peeling strength of the emulsion pressure-sensitive adhesive prepared in the invention can be obtained; the prepared protection film has good fog resistance when applied on sheet materials like steel plates and titanium plates.

Description

technical field [0001] The invention belongs to the field of chemical industry, and in particular relates to a pressure-sensitive adhesive for polyethylene protective film and a polyethylene protective film containing the pressure-sensitive adhesive. Background technique [0002] The protective film is a film-like material used to protect the surface of goods. It is mainly made of polyolefin film as the base material and rubber or acrylate polymer as the pressure-sensitive adhesive, which is coated and dried. Paste it on the surface of various metals, aluminum-plastic panels, plastic sheets, coated steel, stainless steel, titanium plates, aluminum profiles, stone, glass, instruments, furniture, etc. Protects surfaces during processing, storage and use, preventing contamination, scratching and slowing oxidation of product surfaces. The application of protective film can not only improve the appearance quality of products and facilitate material processing, but also improve t...
