Abstract

The preparation method comprises the following preparation processes: (1) taking a PET (Polyethylene Terephthalate) film, and carrying out double-sided corona treatment; (2) coating polyurethane resin on the inner surface of the PET film to form an adhesive layer; compounding with a PVDF (Polyvinylidene Fluoride) film; (3) coating the outer surface of the PET film with polyurethane resin to form an adhesive layer, and performing corona treatment; and compounding with a metal plate to obtain the fluorine film plate. A component with low temperature resistance is introduced into the polyurethane resin, the low temperature resistance of a prepared adhesive layer can be effectively improved, a fluorine film for metal plate film coating is obtained in cooperation with a corona-treated PET film formed through two-way stretching and an ultra-low-temperature-resistant PVDF film, the fluorine film is compounded with a metal plate, and the fluorine film is excellent in multiple environment resistance and good in anti-corrosion performance. And the fluorine film plate has high adhesive force and high flexibility at low temperature, the outer layer of the prepared fluorine film plate is prevented from cracking, the fluorine film plate has good low-temperature adaptability and stability in a warm environment, and the problem that a metal plate film is poor at low temperature is avoided.

Description

technical field [0001] The invention relates to the technical field of metal plate coating, in particular to an ultra-low temperature resistant fluorine film and a preparation method thereof. Background technique [0002] When the metal plate is used as a building material, it is widely used in the walls of large public buildings, public workshops, integrated houses, etc.; in practical application, the metal plate is the substrate, and the surface is covered with film. Existing metal-coated panels are often used in low-temperature freezing and some low-temperature conditions such as minus tens of degrees below zero in some cold areas. It causes problems such as construction difficulties and increased labor costs during replacement. Therefore, we propose an ultra-low temperature resistant fluorine film and its preparation method. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide an ultra-low temperature resistant fluorine film and a prep...
