Abstract

The invention discloses a zero-formaldehyde release water-based wood fragrance board, which comprises a board core, a core board and a surface board, two core boards and a skin board; Bonding of the core and the surface board; the core of the board is plywood or blockboard; and a preparation method thereof. The detection value of the formaldehyde emission of the product is ND, that is, <0.1mg / L, which is a limit that cannot be reached by other similar products on the market. Adding a balanced adhesive film between the facing adhesive film and the slab will increase the elasticity during pressing, reduce surface defects, and improve the bonding strength. The surface pollution is easy to clean, and it is convenient to use. It does not need to be painted, and can be directly used for decoration and furniture manufacturing.

Description

technical field [0001] The invention relates to the technical field of wood processing, in particular to a zero-formaldehyde-releasing water-based wood fragrance board and a preparation method thereof. Background technique [0002] At present, the wood-based panels sold in the market and produced by factories all contain adhesives made of formaldehyde. The content of formaldehyde in the panels is high, and formaldehyde is released in the wood-based panels for a long time. According to literature reports, the longest release time of formaldehyde can reach 14 years. . Now the national standard "GB18580-2008 Formaldehyde Release Limits in Interior Decoration Materials Wood-based Panels and Their Products" stipulates that the minimum release amount is also 1.5mg / L, and there will still be formaldehyde released that is harmful to the human body, especially to children. maximum. [0003] With the emphasis on human health, the requirements for the living environment are getting h...
