Abstract

The invention relates to a paint-free decorative overlay fitment board, in particular to a formaldehyde purification inflaming retarding oriented strand board and a manufacturing method thereof, and belongs to the wood processing industry. The formaldehyde purification inflaming retarding oriented strand board comprises a base material layer, an upper surface layer decorative film adhesive layer and a lower surface layer decorative film adhesive layer. The upper surface layer decorative film adhesive layer and / or the lower surface layer decorative film adhesive layer are immersed with an amino resin adhesive solution and a formaldehyde decomposition adhesive solution, the base material layer is an oriented strand board layer, the oriented strand board layer comprises an upper surface layer, a lower surface layer and a core layer shaving layer, wherein the glue mixing wood shavings on the upper and lower surface layers are longitudinally arranged in the fiber direction, the glue mixing wood shavings on the core layer shaving layer are transversely arranged in the fiber direction, an inflaming retarding layer is arranged between the lower surface shaving layer and the core layer shaving layer, and an inflaming retarding layer is arranged between the upper surface shaving layer and the core layer shaving layer. The manufacturing method of the paint-free decorative overlay fitment board comprises the steps of base material sanding, formaldehyde decomposition adhesive solution preparation, decorative film adhesive manufacturing, assembling and pressing and sticking. The formaldehyde purification inflaming retarding oriented strand board is realistic in effect, low in cost and good in 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...
