Emulsion pressure-sensitive adhesive and PE protection film prepared from same

Abstract

The invention discloses an emulsion pressure-sensitive adhesive and a PE protection film prepared from the same, and aims at providing the PE protection film prepared from the emulsion pressure-sensitive adhesive. The emulsion pressure-sensitive adhesive is prepared from 40-60 parts of acrylate monomers, 0.1-10 parts of functional monomers, 0.1-5 parts of epoxy group containing organosilicone, 0.1-2.0 parts of emulgator, 0.1-0.5 part of initiator and 40-60 parts of water. The surface of bright and clean metal or a coating is covered with the PE protection film prepared from the emulsion pressure-sensitive adhesive, and water stains or ghost patterns or spots or other bad phenomena cannot be left on the surface.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to an emulsion pressure-sensitive adhesive and a PE protective film prepared by using the pressure-sensitive adhesive. Background technique [0002] As a product widely used in industrial production, protective film is usually used to temporarily protect the surface of products or parts to avoid scratches or contamination of the surface during processing, so the protective film came into being , which is mainly used to protect the surface of the product, but will eventually be removed from the surface of the product. Therefore, in general, the protective film needs to have the following characteristics: 1. The protective film needs to be easily attached to the surface of the product to be protected; 2. When the protective film needs to be removed, it can be peeled off from the surface of the protected object with an appropriate peeling force; 3. The surface of the protected object c...

[0002] As a product widely used in industrial production, protective film is usually used to temporarily protect the surface of products or parts to avoid scratches or contamination of the surface during processing, so the protective film came into being , which is mainly used to protect the surface of the product, but will eventually be removed from the surface of the product. Therefore, in general, the protective film needs to have the following characteristics: 1. The protective film needs to be easily attached to the surface of the product to be protected; 2. When the protective film needs to be removed, it can be peeled off from the surface of the protected object with an appropriate peeling force; 3. The surface of the protected object cannot be polluted by the protective film; at present, a Chinese patent with a publication number of 102964512A discloses a An emulsion-type acrylate pressure-sensitive adhesive and a preparation method thereof, comprising methyl methacrylate and vinyl acetate as raw materials to prepare a prepolymer, adding an acrylic diluent for dilution, and simultaneously adding 2-hydroxyethyl methacrylate Carry out modification, adjust its PH value, and finally prepare emulsion-type acrylic pressure-sensitive adhesive. May leave watermarks, mottling or "ghosting" on the surface of the product. "Ghosting" is generally due to a light haze that remains on the surface of the product when the protective film is removed, but this substance is not It is residual glue, which is generally considered to be the result of the migration of low molecular weight substances in the protective film adhesive from the protective film adhesive layer to the pasted surface
