Embodiment 1-3 and comparative example 1-2

[0038] A method for preparing an anti-aging and flame-resistant decorative board with impregnated film paper finish,

[0039] Step 1) Laying adhesive film, medium-density stickers, adhesive film and decorative plates on the substrate layer in sequence to form a blank;

[0040] Step 2) After the blank assembly is completed, put it into a hot press machine for hot pressing. The conditions for hot pressing are: the hot pressing temperature is 130-150°C, the hot pressing time is 5 minutes to 7 minutes, and the hot pressing pressure is 12- 15 kg / cm²;

[0041] The adhesive film is made of kraft paper with a gram weight of 40-60 g / dm2 after being impregnated with phenolic resin, and then dried and formed. The amount of kraft paper impregnated with glue is 180%-250%;

[0042] The medium-density sticker is made of kraft paper with a gram weight of 210-240 grams per square decimeter, which is impregnated with phenolic resin and dried to form a membrane paper. The amount of kraft paper ...

Abstract

The present invention provides a novel ageing-resistant and combustion-resistant wood-based panel with an immersion film paper veneer and a preparation method thereof. The method comprises the following steps: (1) sequentially paving an adhesive film, a medium density decal, an adhesive film and a decorative sheet on a substrate layer and assembling; 2) after assembling is completed, placing in a thermocompressor for hot pressing, wherein the adhesive film is film paper which is obtained by soaking kraft paper with gram weight of 40-60 grams / square decimeter by using phenolic resin and then drying and molding, the adhesive dipping amount of the kraft paper is 180%-250%, the medium density decal is film paper which is obtained by soaking kraft paper with gram weight of 210-2400 grams / square decimeter by using phenolic resin, and the adhesive dipping amount of the kraft paper is 30%-35%; and 3) cropping and trimming an ageing-resistant and combustion-resistant decorative panel. The decorative panel provided by the present invention has low formaldehyde emission and good ageing-resistant and combustion-resistant properties.

Description

technical field [0001] The invention relates to a wood-based panel decorative building material, in particular to an anti-aging and flame-resistant decorative panel with low formaldehyde emission and a preparation method thereof. Background technique [0002] Wood-based panels are made of wood, wood chips, scraps, shavings and their processing residues as raw materials, including plywood, medium density fiberboard, particleboard, hard fiberboard, etc. With the development of wood-based panel secondary processing technology and the continuous improvement of people's quality of life, the demand for high-quality decorative wood-based panels is also increasing. Wood-based panels are widely used in the furniture industry. For example, the cabinet industry mainly uses medium-density fiberboard and particleboard as the base material. After simple finishing or surface paint treatment, decorative and practical values ​​are realized. With the improvement of decoration engineering tec...
