Embodiment 1

[0027] A method for manufacturing a formaldehyde-free resin-impregnated decorative paper veneer wood-based panel that absorbs carbon dioxide, comprising the following steps:

[0028] S1. Preparation of nanocellulose that absorbs carbon dioxide:

[0029] First, prepare nanocellulose by chemical method (mix the pulp with 60% sulfuric acid solution 1:10 (weight ratio), and mechanically stir the reaction in a constant temperature water bath at 45°C for 80 minutes; after the reaction, add A certain amount of distilled water was stirred at a constant speed to terminate the reaction; after standing for 5 hours, the supernatant was removed, and the precipitated part was centrifuged at high speed for 5 times (centrifugation speed 21000 r / min, centrifugation time 10 min), and the remaining turbid solution was transferred to dialysis bag, dialyzed in flowing distilled water until the mixture becomes neutral, that is, nanocellulose is obtained); then the nanocellulose suspension with a ma...

Embodiment 2

[0039] A method for manufacturing a formaldehyde-free resin-impregnated decorative paper veneer wood-based panel that absorbs carbon dioxide, comprising the following steps:

[0040] S1. Preparation of nanocellulose that absorbs carbon dioxide:

[0041] First, prepare nanocellulose by chemical method (mix the pulp with 60% sulfuric acid solution 1:10 (weight ratio), and mechanically stir the reaction in a constant temperature water bath at 45°C for 80 minutes; after the reaction, add A certain amount of distilled water was stirred at a constant speed to terminate the reaction; after standing for 5 hours, the supernatant was removed, and the precipitated part was centrifuged at high speed for 4 times (centrifugation speed 21000 r / min, centrifugation time 10 min), and the remaining turbid solution was transferred to dialysis bag, dialyzed in flowing distilled water until the mixture becomes neutral, that is, nanocellulose is obtained); then the nanocellulose suspension with a ma...

Embodiment 3

[0051] A method for manufacturing a formaldehyde-free resin-impregnated decorative paper veneer wood-based panel that absorbs carbon dioxide, comprising the following steps:

[0052] S1. Preparation of nanocellulose that absorbs carbon dioxide:

[0053] First, prepare nanocellulose by chemical method (mix the pulp with 60% sulfuric acid solution 1:10 (weight ratio), and mechanically stir the reaction in a constant temperature water bath at 45°C for 80 minutes; after the reaction, add A certain amount of distilled water was stirred at a constant speed to terminate the reaction; after standing for 5 hours, the supernatant was removed, and the precipitated part was centrifuged at high speed for 5 times (centrifugation speed 21000 r / min, centrifugation time 10 min), and the remaining turbid solution was transferred to dialysis bag, dialyzed in flowing distilled water until the mixture becomes neutral, that is, nanocellulose is obtained); then the nanocellulose suspension with a ma...

Abstract

The invention discloses a manufacture method of a veneered wood-based panel with formaldehyde-free resin impregnated decorative paper capable of adsorbing carbon dioxide. The manufacturing method comprises preparing nano-cellulose capable of adsorbing the carbon dioxide, regulating acrylic resin capable of adsorbing the carbon dioxide, preparing acrylic resin impregnated decorative paper capable of adsorbing the carbon dioxide, and compounding the acrylic resin impregnated decorative paper capable of adsorbing the carbon dioxide with a wood-based panel. The manufacturing method has the advantages that the acrylic resin is free of free formaldehyde; the wood-based panel is selected from products produced from isocyanate or formaldehyde-free adhesive such as formaldehyde-free soybean glue, such as shaving boards, plywood and fiberboards; the nano-cellulose capable of adsorbing the carbon dioxide is added into the formaldehyde-free acrylic resin; therefore, the veneered wood-based panel with the formaldehyde-free resin impregnated decorative paper can have a carbon dioxide adsorption function and can serve as an indoor household material, the indoor carbon dioxide content is favorablyreduced, the free formaldehyde is eliminated, and indoor air quality is favorably improved.

Description

technical field [0001] The invention belongs to the technical field of wood-based panel processing, and in particular relates to a method for manufacturing a carbon dioxide-absorbing formaldehyde-free resin-impregnated decorative paper-faced wood-based panel. Background technique [0002] Due to the dull surface color of particleboard and fiberboard, the complete solid wood pattern cannot be seen. The plywood produced with inferior logs or fast-growing tree species as raw materials has monotonous surface patterns. Partial defects on the surface of the board improve the use value. At present, melamine resin-impregnated decorative paper is mainly used for decorative paper veneer wood-based panels, which has been widely used in indoor household materials. This kind of melamine resin-impregnated decorative paper contains a small amount of formaldehyde, and excessive use will pose a hazard of free formaldehyde. Contents of the invention [0003] The invention provides a method...
