Board-like cork material and method for producing same

Abstract

The present invention relates to a method for producing a board-like cork material in which the (ultra) fine powder (particles) remaining in the many metaphysical recesses in a cork surface are not drawn out while at the same time ensuring that there is no damage to the specific functionality of cork when employed in the internal space of a business room or elsewhere. The method according to the present invention comprises the steps of: (a) coating an adhesive onto one surface or both surfaces of a substrate of a board-like cork material and then hot pressure bonding and thereby adhering a cork-patterned paper onto the same, and polishing and brushing the surface of the cork-patterned paper; (b) using air vacuum adsorption to remove the fine cork powder which is present in the plurality of metaphysical recesses formed in the surface of the cork-patterned paper, after having passed through Step (a); (c) removing the fine cork powder which remains in the plurality of metaphysical recesses formed in the surface of the cork-patterned paper, by washing the plurality of metaphysical recesses formed in the surface of the cork-patterned paper after Step (b); and (d) infilling the metaphysical recesses with a colouring composition by compressing and thereby impregnating the same by means of a roller coater and at the same time effecting colouration of a level-surface type or else effecting only colouration of a uniform type by excluding calcium carbonate filler from the colouring composition, and printing or top coating by means of a gravure printing roller or spray and then passing through an embossing roller.

Description

technical field [0001] The invention relates to a cork board and a manufacturing method thereof. Using multifunctional cork is more beneficial to human health and indoor sanitation, and it is suitable for residential, commercial interior spaces and various furniture storage spaces, and not only has diverse and ultra-modern features It can also create a hygienic and healthy living space and storage space for daily necessities. Background technique [0002] Cork is a porous cell formed in the epidermis, cortex, primary phloem, and secondary phloem of the cork oak bark. It forms more than 42 million honeycomb-like porous cells per 1 cm. The chemical composition is almost non-existing in Cellulose in the xylem is a natural substance that contains most of the fatty acids and a small amount of lignin, ash, resin and carbohydrates. The cork composed of porous cells is characterized by impermeable, elastic and soft compartments, and the liquid cannot penetrate the aggregate, even t...
