Embodiment 1

[0052] a. Substrate sanding: Use a three-sand frame sander to sand the surface of 18mm ordinary poplar plywood, and the third sanding belt is 180 mesh. Measure its thickness error, the maximum error is 0.11mm. Observe its surface finish, the surface is smooth and clean, without wavy lines;

[0053] b. Formaldehyde decomposition glue preparation: fully mix the formaldehyde decomposition active ingredients and amino resin and stir evenly to obtain the formaldehyde decomposition glue; the mass ratio of the formaldehyde decomposition active ingredients to the formaldehyde decomposition glue is 5%, and the stirring time is 5min; the formaldehyde decomposition is effective The ingredients include chitin, nano-silicon chips and tourmaline powder; tourmaline powder accounts for 1wt% of the mass of formaldehyde-decomposing active ingredients;

[0054] c. Manufacture of decorative adhesive film paper: pass the decorative paper through amino resin glue and formaldehyde decomposition glue ...

Embodiment 2

[0061] a. Substrate sanding or applying veneer: Use a three-sand frame sanding machine to sand the surface of the 16.5mm blockboard core, and the third sanding belt is 200 mesh. Measure its thickness error, the maximum error is 0.22mm. Observe its surface finish, the surface is rough. Cover the surface with a layer of poplar veneer with a thickness of 0.5mm, and the moisture content of the veneer is 10%. and sanded to a smooth surface;

[0062] b. Formaldehyde decomposition glue preparation: fully mix the formaldehyde decomposition active ingredients and amino resin and stir evenly to obtain formaldehyde decomposition glue; the mass ratio of formaldehyde decomposition active ingredients to formaldehyde decomposition glue is 10%, and the stirring time is 10min; formaldehyde decomposition is effective The ingredients include chitin, nano-silicon chips and tourmaline powder; tourmaline powder accounts for 3wt% of the mass of formaldehyde-decomposing active ingredients;

Embodiment 3

[0070] a. Substrate sanding: the substrate is blockboard core or plywood; if the surface finish of blockboard core or ordinary plywood substrate is poor or the thickness error exceeds 0.15mm, the surface needs to be covered with a layer of thickness 0.7mm, containing water The whole veneer with a content rate ≤ 5%, the veneer is usually poplar veneer or reconstituted decorative veneer;

[0071] b. Formaldehyde decomposition glue preparation: fully mix the formaldehyde decomposition active ingredients and amino resin and stir evenly to obtain the formaldehyde decomposition glue; the mass ratio of the formaldehyde decomposition active ingredients to the formaldehyde decomposition glue is 6%, and the stirring time is 8 minutes; the formaldehyde decomposition is effective The ingredients include chitin, nano-silicon flakes and tourmaline powder; tourmaline powder accounts for 5wt% of the mass of formaldehyde-decomposing active ingredients; the mass ratio of chitin, nano-silicon fla...

Abstract

The invention relates to a paint-veneer-free furniture plate, especially relates to a formaldehyde decomposing (purifying) functional biological plate, and a manufacturing method of the biological plate, and belongs to wood processing industry. The biological plate comprises a substrate layer, an upper surface decorative film adhesive paper layer pressed and adhered to an upper surface of the substrate layer, and a lower surface decorative film adhesive paper layer pressed and adhered to a lower surface of the substrate layer. The upper surface decorative film adhesive paper layer or the lower surface decorative film adhesive paper layer has the weight of 60-150 g / m2; the upper surface decorative film adhesive paper layer and / or the lower surface decorative film adhesive paper layer is decorative paper impregnated with an amino resin glue solution and a formaldehyde decomposing glue solution; the decorative paper impregnated with an amino resin glue solution and a formaldehyde decomposing glue solution has the thickness of 0.08-0.12 mm; and the substrate layer has the thickness of 2.5-25 mm. The manufacturing method comprises the following steps: a, substrate sanding; b, adjustment of the formaldehyde decomposing glue solution; c, manufacturing of decorative film adhesive paper; d, assembly; and press adhesion. The formaldehyde purifying biological plate is authentic in decorative effect, low in cost, and good in formaldehyde purifying effect.

Description

technical field [0001] The invention relates to a paint-free decorative furniture board, in particular to a formaldehyde decomposition (purification) functional ecological board and a manufacturing method thereof, belonging to the wood processing industry. Background technique [0002] The status quo of indoor air quality is a focus of social attention. Excessive concentrations of formaldehyde, TVOC, and bacteria seriously affect people's physical and mental health. Ordinary wood-based panel furniture panels use formaldehyde and urea-based adhesives to achieve bonding effects. Although the bonding performance is excellent, the free formaldehyde in them will deteriorate the indoor air quality and cause health risks to the elderly, the infirm or pregnant women. Therefore, functional panels that can absorb and decompose formaldehyde in the air are people's health needs, and they are also the development direction of furniture panels. [0003] The ecological board is based on b...
