Abstract

The invention provides a high-performance formaldehyde-free impregnating glue for woodgrained paper. The impregnating glue comprises the following components, in parts by mass: 50-70 parts of a water-based 3-hydroxy acrylic emulsion, 3-5 parts of water-based epoxy resin, 10-20 parts of water-based amino resin, 3-5 parts of a water-based isocyanate cross-linking agent, 1-2 parts of a water-based zirconium oxide dispersion liquid, 1-2 parts of a water-based polytetrafluoroethylene dispersion liquid, 3-5 parts of a medium-molecular-weight methylsiloxane dispersion liquid, and 20-30 parts of deionized water. The impregnating glue provided by the invention eliminates formaldehyde emission and formaldehyde residues of a final product of traditional melamine-urea-formaldehyde impregnated bond paper in the glue impregnation process; and at the same time, the product has improved comprehensive performance such as bending resistance, abrasion resistance, scratch resistance and high and low temperature resistance, and the quality and production efficiency of the product are 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...
