Abstract

The invention relates to the field of preparation of functional PVC films, and discloses a scratch-resistant PVC film and a preparation method thereof. In the scratch-resistant PVC film provided by the invention, the surface of a PVC film is printed and coated with a functional coating, wherein the functional coating has the thickness of 4-6 microns, and comprises the following components in part by weight: 55-65 parts of polyurethane, 35-45 parts of polymethyl methacrylate and 5-12 parts of aziridine. The production method of the scratch-resistant PVC film provided by the invention comprises the following steps: (1) blending a coating paint; (2) preheating: preheating a PVC surface film at 50-70 DEG C; (3) printing and coating: transferring the preheated PVC surface film into a printing press for coating the coating; (4) drying and cooling: drying the film prepared in step (3) at 50-55 DEG C, cooling and rolling the film to obtain the scratch-resistant PVC film. The process of the invention is simple and easy to operate, low in cost and excellent in effect.

Description

technical field [0001] The invention relates to the field of preparation of functional PVC films, in particular to a scratch-resistant PVC film and a preparation method thereof. Background technique [0002] With the development of thin film technology, there are many kinds of protective films on the market for sticking on the surface of various materials. They are used for surface protection, which can effectively prevent the aging of materials and prolong the quality and service life of materials. Polyvinyl chloride (PVC), as the most produced general-purpose plastic in the world, has also become a pioneer in functional improvement research. [0003] At present, there are many functional PVC films. Most of the preparation methods are to add functional additives to PVC resin and prepare films after blending. In order to improve the impact toughness of materials, people add various rubber elastomers to polypropylene, such as Ethylene-propylene rubber, ethylene-butylene copo...
