Antibacterial transfer film and preparation method thereof

Abstract

The invention relates to the technical field of a transfer film, specifically to an antibacterial transfer film and a preparation method thereof. The antibacterial transfer film comprises a basic film layer, an antibacterial release layer, an UV protective layer and a printing ink pattern layer which are laminated from up to down in sequence. The antibacterial release layer is made from antibacterial release gloss oil, which comprises, by weight part, 20-25 parts of an acrylic resin, 1.0-1.5 parts of an antibacterial finishing agent, 1.0-1.5 parts of a photocatalyst, 6-8 parts of a film forming agent, 0.5-1.0 part of a leveling agent, and 49.0-71.5 parts of a solvent. The antibacterial transfer film can transfer patterns to the surface of a decoration material, has an antibacterial function, and doesn't require secondary processing. The antibacterial transfer film can well adhere to a substrate, is stable in performance and not prone to fade, and can be directly used for transfer bonding of materials. According to the antibacterial transfer film and preparation method thereof, the equipment cost and labor cost are greatly reduced, the production efficiency is improved, and the production cost is reduced.

Description

technical field [0001] The invention relates to the technical field of transfer film, in particular to an antibacterial transfer film and a preparation method thereof. Background technique [0002] Thermal transfer film is a kind of medium material for thermal transfer process. The thermal transfer decoration process is a process of transferring the decorative pattern on the thermal transfer film to the surface of the decorated building material through one-time heating of the thermal transfer film to form a high-quality decorative film. During the thermal transfer process, the protective layer and the pattern layer are separated from the polyester substrate by the combined action of heat and pressure, and the hot melt adhesive makes the entire decorative layer and the substrate permanently bonded. By heating the high-temperature silicon roller, temperature and pressure are applied to the transfer foil, so that the transfer layer composed of decorative wood grain printing l...

AI Technical Summary

Problems solved by technology

At present, there is no direct antibacterial transfer film product on the market, and most of them are cleaned and sterilized on a regular basis, but this method has the following disadvantages: 1. It cannot be continuously antibacterial through regular cleaning and sterilization; 2. Regular cleaning and sterilization Bacteria require labor and cause environmental pollution

There are still patterns on the market first and then secondary processing dipping and spraying anti-bacterial coating for protection. This method is troublesome and affects the aesthetics of the surface pattern of the decorative material.
