Problems solved by technology

[0003] At present, the stain resistance of the coating film is mainly improved by adding fluorine-modified polymers, but such a one-sided increase in the use of fluorine-modified polymers results in high costs, environmental pollution, and complicated process requirements, which greatly limits the application of coatings. scope

Abstract

The invention discloses a self-cleaning scratch-resistant film and a preparation method of its surface film, which belong to the field of a functional film. The preparation method has the advantages of simple process, high safety, environmental friendliness and cost saving, and the obtained coating film is scratch-resistant and has a self-cleaning function. The film of the invention comprises a nano-coating, a self-cleaning scratch-resistant surface film, an aqueous ink layer and a PVC printing base film from top to bottom; the self-cleaning scratch-resistant surface film takes PVC sheet as abase material, and the surface of the base material is an adhesion layer and a transparent layer from bottom to top; the transparent layer paint comprises the following components by mass ratio: 10% to 20% of a reactive diluent, 5% to 20% of a soft component, 50% to 80% of a hard component, 2% to 5% of a light-induced agent, and 0.1% to 0.5% a defoamer; a mixed paint is applied on the substrate bya micro-concave precision coating method, and then is dried by a suspension oven, and finally, oxygen-blocking ultraviolet curing is carried out to obtain the self-cleaning scratch-resistant surfacefilm.

Description

technical field [0001] The invention belongs to the field of functional films, and in particular relates to a self-cleaning scratch-resistant film and a preparation method of the mask. Background technique [0002] The coating film on the surface of automobiles, furniture and other objects is easily damaged by oil stains, dust or human scratches during use, resulting in weakened gloss, obvious scratches, and oily surfaces, which seriously affect the quality and appearance of the coating film. Therefore, self-cleaning has become a measure An important indicator of coating film performance. Having a certain self-cleaning property means that the coating film can keep the surface of the material glossy and beautiful for a long time, and at the same time have a certain self-cleaning property, which makes the decorative material have a longer service life and is easier to clean and care. [0003] At present, the stain resistance of the coating film is mainly improved by adding fl...
