Embodiment 1

[0029] 1) Put 40 parts of deionized water in a container, heat it in a constant temperature water bath, add 30 parts of gum arabic and 10 parts of maltodextrin into the container in turn, stir to make them fully dissolve, and prepare the wall material;

[0030] 3) Add 20 parts of floral essence to the wall material that has been stirred evenly, stir to make it fully dissolve, and shear at a high speed with a high-pressure homogenizer to form an oil-in-water emulsion; the speed of the high-speed homogenizer is 8000 / min, and the The cutting time is 15 minutes, and the homogeneous pressure is 1000bar.

[0031] 4) The oil-in-water emulsion is spray-dried, the feed rate is 5 / min, the air inlet temperature is 190°C, and the air outlet temperature is 90°C. That is, rose essence-starch-based microcapsules are obtained.

[0032] 5) Completely immerse the decorative base paper in the formaldehyde-free adhesive reported in patent ZL 202010394935.8 for 30s, and dry it at 80°C. The amount...

Abstract

The invention discloses a fragrance-releasing facing artificial board and a preparation method thereof. The preparation method comprises the steps that decorative raw paper is completely soaked in a formaldehyde-free adhesive for 30-60 s and dried at the temperature of 80-110 DEG C till no redundant glue solution exists on the paper surface and the paper surface is not sticky to hands, wherein the gluing amount of dry glue in the step is 30-50% of the quantitative amount of the raw paper; after the raw paper is dried, sizing is conducted in the mode that surface coating and back coating are separated, wherein back glue is formaldehyde-free adhesive, and the total sizing amount is 20-50% of the quantitative amount of the raw paper; the surface glue is a formaldehyde-free adhesive added with essence sustained-release microcapsules, a multi-time ultra-thin coating mode is adopted, the thickness of each dry coating is 1-2 microns, and the total gluing amount of the surface glue is 20-30% of the quantitative amount of the body paper; complete drying is performed at 90-110 DEG C; and the impregnated bond paper is hot-pressed on the formaldehyde-free artificial board for 0.5-2 minutes at the pressure of 4-6 Mpa and the temperature of 140-220 DEG C to obtain the formaldehyde-free artificial board. The prepared fragrance-releasing veneer artificial board has the effects of being free of formaldehyde, beneficial to fragrance release and capable of meeting the requirement for the physical strength of the veneer.

Description

technical field [0001] The invention relates to a fragrance-releasing type decorative wood-based panel and a preparation method thereof, belonging to the technical field of wood-based panel processing. Background technique [0002] With the improvement of people's living standards and environmental protection awareness and the society's attention to the air quality of the living room environment, people have begun to pay attention to the smell of home decoration wood materials and their products. Wood-based panels are the main material for interior decoration and furniture, and usually emit odors. As the degree of home improvement and the amount of furniture owned gradually increase, the indoor odor problem becomes more serious. According to market research, in recent years, up to 1% of interior decoration and furniture companies have been complained by customers because of odor, and it is on the rise. Aromatic smells often bring people a pleasant mood, because many spices ...
