Abstract

The invention relates to the technical field of film adhesives, in particular to formaldehyde-free impregnated film adhesive and a preparation method thereof. A base material of the film adhesive is soaked in a formaldehyde-free dipping glue solution, and then the dipped base material is taken out and dried so as to obtain the film adhesive. The formaldehyde-free dipping glue solution is prepared from the following raw materials in parts by weight: 30-60 parts of water-based PUA resin, 8-15 parts of an emulsifier, 5-10 parts of a dispersing agent, 5-10 parts of a penetrating agent special for wood, 3-8 parts of a wetting agent and 50-100 parts of water. According to the invention, the base material can be directly dipped in the formaldehyde-free dipping glue solution, the formaldehyde-free dipping glue solution fully permeates the base material, and the prepared film adhesive really does not contain formaldehyde and has good environmental protection property. In addition, due to full dipping of the dipping glue solution, the prepared film adhesive has excellent fullness, luster, hardness, solvent resistance and weather resistance, does not change color or turn yellow during high-temperature baking, and is high in product quality.

Description

technical field [0001] The invention relates to the technical field of film paper, in particular to a formaldehyde-free impregnated film paper and a preparation method thereof. Background technique [0002] China is the world's largest wood-based panel producer and also the largest furniture producer. Currently, the production of wood-based panels exceeds 300 million cubic meters. The wood-based panel furniture needs to be finished. The common ones are melamine formal impregnated paper finish, wood veneer finish, paint finish, etc. Among them, the effect of melamine paper finish is much higher than other finishes, and , low cost and high processing efficiency. [0003] With people's increasing requirements for environmental protection, the production of wood-based panels and the greening of products are becoming more and more popular. More and more wood-based panel manufacturers have begun to produce formaldehyde-free particle boards, multi-layer boards, and fiberboards. ...
