Abstract

The invention relates to an antibacterial varnish for color plates and a production process for color plates. The antibacterial varnish contains the following components in mass fractions: polyester resin 15-40%, methanol-modified melamine formaldehyde resin 10-30%, propylene glycol methyl ether acetate 0~15%, 2-methyl propanol acetate 0~15%, solvent naphtha 0~10%, cyclohexanone 0~5%, xylene 0~5%, octanol 1~10% and Nano silver-loaded silicone 1-2%; color plate production process includes the following steps: S1. Material preparation (including S1-1 substrate uncoiling and S1-2 primer, back paint, intermediate paint, ink and antibacterial varnish preparation); S2. Substrate pretreatment; S3. Primer coating; S4. Back paint coating; S5. Intermediate coating; S6. Ink printing; S7. Varnish coating. The antibacterial varnish prepared by the invention has good antibacterial performance, so that the colored steel plate prepared by using the antibacterial varnish has good antibacterial performance.

Description

technical field [0001] The invention relates to the technical field of film coating on the surface of steel plates, in particular to an antibacterial varnish for color plates and a production process for color plates. Background technique [0002] Colored steel plate, also known as color coated steel plate, is a product made of cold-rolled steel plate, electro-galvanized steel plate, hot-dip galvanized steel plate or galvanized steel plate as the substrate after various surface treatment processes and then baked. [0003] The traditional method of producing colored steel plates is usually to perform pretreatment such as degreasing on the substrate before passivation treatment. After the passivation film is formed on the surface of the substrate, the substrate is sprayed with primer, dried, sprayed with topcoat, and dried in sequence. , color ink printing or color film lamination and other processes to prepare color steel plates that meet production standards. Color steel pl...
