Abstract

The invention relates to a preparation method of an ylate emulsion plant glue used for a reflective membrane, which comprises the steps of pre-emulsion preparation, initiator aqueous solution preparation, reaction and the like. According to the invention, the ylate emulsion plant glue replaces a solvent type plant glue for reducing 40% of production cost; the aqueous plant glue and the base material enable excellent bonding performance, after the bonding, the membrane surface is flat and smooth, no leakage is generated, no capillary is generated; the technology is simple, the operation is convenient, the plant glue is easy to clean; the performance of the ylate emulsion plant glue is better than the performance of solvent type plant glue, and the plant glue of the invention has the advantages of small scent, low VOC content, health, safety, environmental protection, saved energy consumption and the like.

Description

technical field [0001] The invention relates to a preparation method of polyacrylate emulsion, in particular to a preparation method of polyacrylate emulsion plant glue for reflective film. Background technique [0002] Reflective film is a PVC film with a special structure that uses optical principles to retroreflect light back to the light source. It consists of a film layer with good weather resistance, a tiny glass bead layer, a focusing layer, a reflective layer, an adhesive layer and a peeling layer. Reflective film is mainly used for guide signs and signs of various roads and railways, safety signs of mines and airports, stage scenery, trademarks, place names, license plates, etc. [0003] The existing bead-planting adhesives for reflective films are all solvent-based polyacrylic resins, which are coated with PET or PVC as the base material by a high-precision coating machine, and the acrylic resin is baked and cured to ensure that the glass beads It can be firmly e...
