Antibacterial liquid decorative paper production process

Abstract

The invention discloses an antibacterial liquid decorative paper production process, comprising the steps of 1) preparing urea formaldehyde adhesive; 2) preparing modified melamine adhesive; 3) uncoiling raw paper; 4) pre-wetting; 5) soaking; 6) drying, and spraying; 7), drying, and coating; 8) cutting, and inspecting before storage. The production flow herein is simple, and the production process is convenient to control; the prepared adhesives of low molar ratio and white corundum form composite macromolecular material; through a special drying curve, high brightness, good wear resistance and high vividness are achieved; the decorative paper has formaldehyde release of </=0.5, with other properties kept unchanged; the decorative paper produced according to the process is a functional material; after the decorative paper is compacted into a floor, the nano material may form a trace ozone thin layer on the surface of the floor to inhibit or kill bacteria; meanwhile, the other properties of the floor are unaffected; the floor is particularly suitable for kindergartens, hospitals and other public places.

Description

technical field [0001] The invention relates to an antibacterial liquid decorative paper production process. 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 needs to prep...

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 limits 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; secondly, the production of decorative paper The last process is inspection and warehousing. Usually, the decorative paper for inspection and warehousing is directly placed horizontally on the horizontal pallet. However, when it is placed in the automatic press, the manipulator is used to automatically grab the decorative paper. When forming blanks, due to the presence of decorative paper Different degrees of warped edges lead to the failure of the photoelectric detection of the automatic press, misoperation, and the inability to complete the blank assembly; moreover, the existing decorative paper is cut first, and after cutting, it is manually arranged one by one, usually a dozen decorative papers Stacks of paper are placed on a horizontal square tray, which not only complicates the work procedure and is labor-intensive, but also is not conducive to the orderly sorting of decorative papers, which is prone to errors, and the stacks of decorative papers are calculated during the sorting process. The amount is large, which greatly increases the labor cost, and at the same time, due to the existence of warped edges, it affects the subsequent operation and use; and when the general fiber paper is sorted one by one, there is no equipment that can be directly used for finishing, resulting in decoration. Stacks of paper are limited
