Production process of antibacterial wear-resistant decorative paper

Abstract

The invention discloses a production process of antibacterial wear-resistant decorative paper, comprising the following steps: 1) preparation of urea-formaldehyde glue; 2) preparation of modified triamine glue; 3) unwinding of base paper; 4) pre-wetting; 5) dipping; 6) drying , spraying; 7) drying, coating; 8) cutting, inspection and warehousing; the production process adopted in the present invention is simple, the operation and control are convenient, and the prepared low molar ratio glue is used to form a composite polymer material with white corundum. After a special drying curve, high gloss, wear resistance, and high definition are achieved, and the formaldehyde emission of the decorative paper is ≤0.5, while other properties of the decorative paper remain unchanged; the decorative paper produced according to the process of the present invention is a functional material. After the decorative paper is pressed into the floor, the nano-material will form a thin layer of ozone on the surface of the floor to inhibit or kill bacteria. At the same time, the other functions of the floor must not be affected, especially suitable for kindergartens, hospitals and other public places.

Description

technical field [0001] The invention relates to a production process of antibacterial wear-resistant decorative paper. Background technique [0002] After the veneer paper is impregnated with melamine glue and some additives, it is melamine decorative paper. And boards (density board, particle board, plywood), after hot pressing of steel plates in hot presses, they become decorative boards. The national standard GB / T28995 requires that the formaldehyde emission of decorative paper is 1.5mg / L for grade A and 3.0mg / L for grade B. [0003] At present, the decorative paper has good decorative performance after dipping and gluing, but its formaldehyde release is large, which is not environmentally friendly and healthy; and its wear resistance is not high enough, and the surface is not bright enough, which shortens the life of the decorative paper. The clarity is not high enough, and the production process is relatively complicated; in addition, the existing decorative paper nee...

Problems solved by technology

[0003] At present, the decorative paper has good decorative performance after dipping and gluing, but its formaldehyde release is large, which is not environmentally friendly and healthy; and its wear resistance is not high enough, and the surface is not bright enough, which shortens the life of the decorative paper. The clarity is not high enough, and the production process is relatively complicated; in addition, the existing decorative paper needs to prepare qualified glue before impregnation, and the preparation of glue is the key to the impregnation of the entire decorative paper. The constant temperature storage system restricts the use of glue in winter and summer. The glue is not viscous enough in winter and the temperature of glue is high in summer, which is not conducive to the use in the impregnation process, which affects the production of decorative paper.
