A kind of preparation method of super weather-resistant and anti-corrosion fluorine film plate

Abstract

The invention discloses a preparation method of a super-weather-resistant and anti-corrosion fluorine membrane plate, which comprises a Baosteel plate, a PVDF super-weather-resistant and anti-corrosion composite film, a laminating machine and a secondary control board. The two layers of the polymer film are fixed and welded with a PVDF super weather-resistant and corrosion-resistant composite film away from the outer surface of the Baosteel plate. The surface of one side of the antibacterial layer is fixed with an anti-ultraviolet layer, and one side of the polymer film is fixed to contain a PET film, and the interior of the polymer film is located on the other side of the PET film to contain an EVA polymer film. Both surfaces of the Baosteel plate are fixed and evenly provided with surface expansion grooves, a contact switch is fixedly installed at the inner bottom of the secondary control panel, and a movable pressing plate is movably installed on the upper surface of the return spring inside the secondary control panel. The present invention has the characteristics of increasing the outdoor weather resistance, increasing the service life and avoiding the waste of raw materials in the production process.

Description

technical field [0001] The invention relates to the technical field of diaphragm production, in particular to a method for preparing a super weather-resistant and anti-corrosion fluorine diaphragm. Background technique [0002] Green building materials have been strongly encouraged and assisted by the state in recent years. Due to the deteriorating environmental and weather conditions, the state has promulgated and implemented a series of air control programs to strictly limit VOC emissions. Under the guidance, the production and application of traditional color-coated plates (color steel plates) are increasingly restricted. Since adhesives and solvents are not used in lamination processing, it does not contain formaldehyde, and the plastic film can be beautified and decorated, antibacterial, anti- Dyeing and other treatments ensure the safety and health of the human body, and at the same time play a role in environmental protection. The laminated board used in the canning i...

Problems solved by technology

[0003] At present, fluorocarbon (PVDF) resin color-coated panels are commonly used in the steel structure workshop panel market, represented by Baosteel, which adopts a three-coating and two-baking process. The outdoor weather resistance is about 15 years, and the service life is too short, resulting in excessive scrapping of materials. Faster, the number of raw materials scrapped is large; in addition, in the existing working process of the film-coated board, due to the gap between the two boards, the film will rotate additionally, resulting in waste of film raw materials
