Abstract

The invention discloses PE (polyurethane) protective film glue and a preparation method thereof. The PE protective film glue consists of the following components in parts by weight: monomers: 20-60 parts of butyl acrylate, 25-45 parts of methyl methacrylate, 12-32 parts of methyl acrylate, 5-15 parts of acrylic acid, 10-24 parts of hydroxyethyl acrylate, 120-140 parts of enthyl hexyl acrylate; emulsifying agents: 0.5-1.5 parts of polyoxyethylene octyl phenyl ether, 0.5-1.5 parts of sodium dodecyl sulphate, 0.5-1.5 parts of sodium dodecyl benzene sulfonate; a solvent: 280-350 parts of deionized water; and an initiating agent: 0.6-1.5 parts of ammonium persulfate. The PE protective film glue provided by the invention is the water-based adhesive and has the advantages of environment friendliness, no pollution, strong adhesive force and adhesive strength, and short drying time. A PE protective film coated with the PE protective film glue provided by the invention can be used for a vehicleprotective film, the protective films of all home appliances and so on. The effects of non-degumming and no residue glue can be realized.

Description

Technical field [0001] The invention relates to the field of chemistry and chemical engineering, in particular to a PE protective film glue and a preparation method thereof. Background technique [0002] Protective film is a film-like material with protective function on the surface of other materials. It is mainly made of polyolefin film as substrate, rubber or acrylate polymer as adhesive, and processed by coating and drying methods. The product is mainly used for surface protection of various products with high requirements on surface conditions, such as car protective film, protective film for all home appliances, etc., to prevent surface scratches, pollution and wear during handling, processing, storage and installation. Etc., so as to keep the good appearance of the article, and improve the grade and yield of the product, so the market for protective film is very huge. [0003] The biggest feature of the protective film, especially the surface protective film for outdoor use...
