Abstract

The present invention relates to a paint-free decorative furniture plate and particularly relates to a formaldehyde decomposition (purification) function plate and a preparation method thereof. The plate comprises a substrate layer and an upper surface layer decorative film paper layer and a lower surface layer decorative film paper layer which are respectively pressed and glued to the upper surface and the lower surface of the substrate layer. The gram weight of the upper surface layer decorative film paper layer or the lower surface layer decorative film paper layer is 60 to 150 grams per square meter. The upper surface layer decorative film paper layer and / or the lower surface layer decorative film paper layer is decorative paper which is impregnated with an amino resin solution and a formaldehyde decomposition solution, the thickness of the decorative paper is 0.08 to 0.12 mm, the thickness of the substrate layer is 2.5 to 25mm, and the substrate layer is an oriented strand board layer. The preparation method comprises the steps of (a) substrate sanding, (b) formaldehyde decomposition solution modulation, (c) decorative film paper manufacture, (d) assembly and (e) pressing. The formaldehyde purification plate has the advantages of lifelike decoration effect, low cost and good formaldehyde purification effect.

Description

technical field [0001] The invention relates to a paint-free decorative furniture board, in particular to a formaldehyde decomposition (purification) functional 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 Chinese utility model patent with publica...
