Abstract

The invention discloses a formaldehyde-free paint-free water-based fiberboard. The fiberboard is characterized by being of a multi-layer plywood structure, and is provided with a central layer 1, longmiddle plate layers 2, short middle plate layers 3, balance buffer layers 4 and decorative paper layers 5, wherein the long middle plate layers 2, the short middle plate layers 3, the balance bufferlayers 4 and the decorative paper layers 5 are sequentially laminated from the central layer 1 to outer layers; the center layer 1 is a radiata pine integrally-spliced long middle plate with the thickness of 7 mm; and the thickness of the formaldehyde-free paint-free water-based fiberboard of the multi-layer plywood structure is 17.0mm + / - 0.1 mm, and formaldehyde content is 0. According to the formaldehyde-free paint-free water-based fiberboard and the preparation process thereof, special material selection and a special processing technology are adopted, so that a novel formaldehyde-free paint-free water-based fiberboard of the multi-layer plywood structure is provided, and therefore the purpose of reducing cost is achieved on the premise that product quality is guaranteed not to be reduced.

Description

technical field

[0001] The invention relates to the technical field of wood-based panel production, in particular to an aldehyde-free, paint-free water-based woody board and a preparation process thereof. Background technique

[0002] Formaldehyde-free paint-free water-based wood fragrance board is a new product derived from water-based formaldehyde-free glue applied to plywood and blockboard paint-free ecological boards. Wood-based panel products for decoration and furniture. Such products are produced by using expensive water-based formaldehyde-free adhesives instead of cheap aldehyde-containing adhesives. The more glue layers are used in the material assembly, the higher the production cost of the product will be. Therefore, in order to reduce the number of adhesive layers when the product is assembled and control the production cost, the thin plate products (thickness 5mm, 7mm, 9mm) of the aldehyde-free paint-free water-based wood fragrance board adopt the plywood-like ...
