Skin-touch and scratch-resistant film and preparation method of skin-touch and scratch-resistant surface film

Abstract

The invention discloses a skin-touch and scratch-resistant film and a preparation method of a skin-touch and scratch-resistant surface film and belongs to the field of functional films. The preparation method is simple in process and high in safety, and is capable of reducing cost and preparing the skin-touch and scratch-resistant film with high ductility. The skin-touch and scratch-resistant filmcomprises a nano coating, a skin-touch and scratch-resistant surface film, a water-based ink layer and a PVC printing bottom film which are successively arranged from top to bottom; the skin-touch and scratch-resistant surface film takes a delustering sheet as a substrate; an adhesion layer, a transparent layer and a skin-touch layer are successively arranged on the surface of the substrate frombottom to top; a coating of the transparent layer is prepared from the following component in percentage by mass: 10-15% of reactive diluent, 40-80% of soft component, 10-30% of hard component, 2-5% of photoinitiator and 0.1-0.5% of flatting agent; a coating of the skin-touch layer is prepared from 3-5% by mass of elastic fluff powder. The preparation method of the skin-touch and scratch-resistantsurface film comprises the following steps: coating a mixed coating on the substrate by using a micro-gravure precise coating method, drying by using a suspended drying box, and finally carrying outoxygen-free ultraviolet curing to obtain the skin-touch and scratch-resistant surface film.

Description

technical field [0001] The invention belongs to the field of functional films, and in particular relates to a skin-feeling scratch-resistant film and a preparation method thereof. Background technique [0002] The coating film on the surface of automobiles, furniture and other objects is astringent during production and feels uncomfortable, which seriously affects the texture and appearance of the coating film. Therefore, the scratch resistance of the skin feeling has become an important index to measure the performance of the coating film. Good skin feel and scratch resistance means that the coating film can make the surface of the material have a very comfortable feel and gloss, and make the decorative material last longer. [0003] At present, the hand feeling of the coating film is mainly improved by water-based polymer coating film. Due to the low hardness of the water-based coating film, the scratch resistance and solvent resistance of the coating film are poor. In thi...

Problems solved by technology

[0003] At present, the hand feeling of the coating film is mainly improved through the water-based polymer coating film. Due to the low hardness of the water-based coating film, the scratch resistance and solvent resistance of the coating film are poor. In this way, the water-based polymer coating film is used to improve the hand feeling of the coating film. The scope of application of the coating is limited, and the preparation process is complex, with high requirements for equipment and low safety factor
