[0005] However, the above-mentioned PE protective film has the following defects: since the PE protective film is formed by melt co-extrusion and blowing of three layers of PE film layers, the PE film layer and the adhesive layer will gradually separate during long-term use. The PE film layer will fall off easily

Abstract
The invention relates to a high-adhesion PE protective film and a preparation method thereof, comprising a PE film layer and an adhesive layer, the inner layer of the PE film layer comprising 35-40 parts of HDPE, 5-15 parts of LLDPE, 10-10 parts of SEBS 20 parts, 5~10 parts of toughening filler, 1~5 parts of sodium carboxymethyl cellulose, 3~5 parts of tea saponin, 1~3 parts of heat stabilizer and 1~2 parts of antioxidant, peroxide exchange 1-3 parts of joint agent; the adhesive layer includes 30-35 parts of acrylic acid, 50-60 parts of acrylates, 10-15 parts of methyl vinyl silicone rubber, 5-10 parts of thickening filler, tea saponin ‑1-5 parts of acrylate-based wetting agent, 1-3 parts of silane coupling agent and 1-3 parts of cross-linking agent; the inner layer and adhesive layer, PE film layer and adhesive layer prepared by the above formula The adhesion between them is strong, so as to prevent the PE film layer from falling off easily.
Description
technical field [0001] The invention relates to the technical field of PE protective films, in particular to a high-adhesion PE protective film and a preparation method thereof. Background technique [0002] In recent years, the demand for aluminum alloy profiles has been increasing, and many industries have launched plans to "replace steel with aluminum" or "replace wood with aluminum". The reasons why aluminum alloy profiles are widely used are: 1) The content of aluminum elements is very rich , and the difficulty of mining is small; 2) aluminum alloy is easy to process and shape; 3) aluminum alloy is easy to surface treatment; 4) aluminum alloy has good heat dissipation; in the process of using aluminum alloy profiles, PE protective film is usually pasted on the surface of aluminum alloy profiles, PE protective film mainly has milk white type and black and white type, which can meet the needs of different fields. [0003] The PE protective film includes a PE film layer a...
