Abstract
The invention provides a preparation method of an anti-ultraviolet card protecting film, and belongs to the technical field of anti-ultraviolet mechanisms. The preparation method of the anti-ultraviolet protective card film comprises the following steps: S1, preparing raw materials for preparing the anti-ultraviolet protective card film; S2, mixing the raw materials subjected to load bearing together; S3, carrying out melt extrusion on the raw materials; S4, rapidly cooling the extruded raw materials; s7, the tidy thin film is cut; and S8, the cut sheet-shaped thin film is packaged. When the card protecting film is used, the film is cut into the sheet-shaped film in a specified shape through the cutting machine, the sheet-shaped film is moved into the packaging machine through the grabbing mechanism, packaging of the sheet-shaped film is achieved, the card protecting film is higher in ultraviolet resistance, meanwhile, the card protecting film has the advantages of being resistant to tension, waterproof, fireproof, insulated, resistant to corrosion and the like, and the service life of the card protecting film is prolonged.
Description
technical field [0001] The invention relates to the field of anti-ultraviolet mechanism, in particular to a preparation method of an anti-ultraviolet protective card film. Background technique [0002] Card protection film, also known as over film, is widely used in the sealing and protection of various sheet materials such as ID cards, cultural and historical materials, photos, pictures, credit cards, licenses, business licenses, precious letters, securities, passes, representative cards, etc. The plastic-encapsulated sheet material has excellent characteristics such as waterproof, anti-alteration, moisture-proof, moth-proof, mildew-proof, corrosion-resistant, etc., and it is crisp and beautiful, and the transparency is improved. [0003] At present, the existing methods for preparing anti-ultraviolet card protection film, the prepared card protection film has weak anti-ultraviolet ability, and its properties such as tensile resistance, waterproof, fire prevention, insulati...
