Abstract

The invention provides a high-performance formaldehyde-free wood grain paper impregnating glue, comprising the following components in parts by mass: 50-70 parts of water-based 3-hydroxy acrylic emulsion, 3-5 parts of water-based epoxy resin, and 10-10 parts of water-based amino resin. 20 parts, 3-5 parts of water-based isocyanate cross-linking agent, 1-2 parts of water-based zirconia dispersion, 1-2 parts of water-based polytetrafluoroethylene dispersion, 3-5 parts of medium molecular weight methylsiloxane dispersion, remove 20 to 30 parts of ionized water. It eliminates the formaldehyde emission of traditional melamine-impregnated adhesive film paper during the dipping process and the formaldehyde residue in the final product. The product quality and production efficiency have been improved.

Description

technical field [0001] The invention relates to the technical field of wood grain paper production, in particular to a high-performance formaldehyde-free wood grain paper impregnated glue and a preparation method. Background technique [0002] Wood grain sticker, also known as melamine impregnated film paper, is a kind of plain base paper or printed decorative paper impregnated with amino resin (melamine formaldehyde resin and urea-formaldehyde resin) and dried to a certain extent, with a certain resin content and volatile matter content. , can be glued to each other or to wood-based panel substrates after hot pressing, and are widely used in surface cladding and appearance decoration in furniture, door industry, cabinets, home decoration and other fields. The current dipping glue is a mixed solution of melamine-formaldehyde resin or urea-formaldehyde resin and related functional additives. Formaldehyde is one of the effective components of this type of resin. Formaldehyde m...
