Problems solved by technology

[0003] The matte film is usually made by adding matting powder to the resin coating to achieve a matte effect. The traditional matte film needs to strictly control the viscosity of the paint and the particle size of the matting powder. , due to the insolubility of the matting powder, it is easy to precipitate in the paint, resulting in uneven matteness of the matte film produced, and at the same time, local paint sags will also occur after the paint is sprayed, which will affect the surface appearance of the matte film

Abstract

The invention discloses a scratch-resistant matte film and a preparation method of a scratch-resistant matte surface film, and belongs to the field of functional films. The preparation method adopts simple process and is high in safety, and the film with scratch resistance, uniform matte degree and flat and smooth surface can be obtained. The scratch-resistant matte film comprises a nano-coating,the scratch-resistant matte surface film, a water-based ink layer and a PVC printed bottom film from top to bottom sequentially, wherein the scratch-resistant matte surface film adopts a matted pieceas a substrate, an adhesion layer and a transparent layer are arranged on the substrate surface from bottom to top sequentially, and the transparent layer is prepared from components in a mass ratio as follows: 10%-15% of a reactive diluent, 30%-50% of a soft component, 30%-50% of a hard component, 2%-3% of a photoinitiator, 5%-10% of matting agent, 0.1%-0.5% of a leveling agent and 0.5%-1% of a wetting dispersant. Mixed paint is applied to the substrate in a micro-concave precise coating way and dried by a suspended drying oven, and finally, the scratch-resistant matte surface film is obtained by oxygen-insulated ultraviolet curing.

Description

technical field [0001] The invention belongs to the field of functional films, and in particular relates to a matte scratch-resistant film and a preparation method thereof. Background technique [0002] The coating film on the surface of automobiles, furniture and other objects is easily damaged by sand, stones, washing or artificial scratches during use, resulting in weakened gloss and obvious scratches, which seriously affect the quality and appearance of the coating film. Therefore, scratch resistance has become a measure of coating quality. An important indicator of membrane performance. High scratch resistance means that the coating film can keep the surface of the material glossy and beautiful for a long time, so that the service life of the decorative material is longer, and now people's quality of life is improved, and the use of cars, furniture and other objects pays attention to texture, while These objects cannot fully meet people's needs when they are manufactur...
