Problems solved by technology

[0002] At present, the laser cutting protective film for stainless steel plate in my country's domestic market mainly relies on imported products, which are mainly monopolized by France's Novasell, Germany's Polyfim and Japan's Nitto, especially the stainless steel coil grinding wire has a fast drawing speed. High efficiency, the temperature of the stainless steel film is about 50 degrees, the technical requirements for the protective film are extremely high, and there is an urgent need for a protective film that can solve the focusing and reflection problems of fiber laser cutting

Abstract

The invention belongs to the technical field of laser cutting protective films, and discloses a stainless steel roll-grinding hot-pasting laser cutting protective film which is prepared from the following raw materials in percentage by weight: 30%-40% of low-density polyethylene, 35%-40% of linear polyethylene, 10% of metallocene, 5%-10% of high-density polyethylene and 10% of special coloring master batch. The glue is prepared from the following raw materials in percentage by weight: 4% of acrylic acid, 25% of butyl acrylate, 50% of 2-ethylhexyl acrylate, 11% of vinyl acetate, 5% of methyl methacrylate and 5% of hydroxyethyl acrylate, and the preparation process comprises the following steps: (1) producing a PE base material in a blow molding manner;, (2) producing the glue; (3) coating in a net wire roller transfer coating manner; (4) carrying out high-temperature curing in a curing chamber for 48 hours; and (5) cutting. The problems of focusing and reflection in fiber laser cutting can be solved, the technology that a stainless steel plate is thermally pasted with a fiber laser cutting protective film is broken through, the actual application requirement can be met, and the application range is wide.
