[0026] Preparation of charcoal plates

[0027] Fine charcoal from high-quality oak (Quercus variabilis BL) from Wonju-shi, Kangwon-do (Korea) was used to prepare charcoal plates made of porous carbonaceous materials.

[0028] Comprising 7% by weight of charcoal particles with a particle size of 6 to 12 mesh, 14% by weight of charcoal particles with a particle size of 12 to 18 mesh, 43% by weight of charcoal particles with a particle size of 18 to 40 mesh, 23% by weight of Charcoal particles having a particle size of 40 to 60 mesh, 9% by weight of charcoal particles having a particle size of 60 to 100 mesh, and 4% by weight of charcoal particles having a particle size of 100 mesh or less A binder of polyvinyl acetate resin latex (non-volatile: 42%) by weight and isocyanate resin was mixed in an amount of 5% by weight. Mixture at 30kgf / cm 2 Go through the primary hot pressing step for 1 minute under pressure at 10kgf / cm 2 Go through the secondary hot pressing step for 1 min...

[0032] Preparation of charcoal sheet plies with chemical fiber nonwovens

[0033] After the method of Example 1, a mixed charcoal board (fine charcoal board) was prepared and a polypropylene nonwoven was adhered thereto. The non-woven fabric has 30g / m 2 The basis weight, the thickness of 0.12mm and the porosity of 39.3%. The binder is polyvinyl acetate resin latex (non-volatile: 42%) and is used at 80 g / m 2 amount of coating. The sheet passes through the heating temperature at 100°C and 10kg / cm 2 Prepared by autoclaving at a pressure of 2 min. product in figure 2 shown in .

Abstract

Disclosed herein is a method for preparing a functional charcoal board laminate comprising a thin paper with a printed pattern or a non-woven fabric of chemical fibers on a side of a charcoal board which has superior appearance while maintaining properties of charcoal such as dehumidification, moisturization, ventilation, adsorption and the like, thereby providing air purification effect by adsorbing offensive odor and harmful gas, emitting far-infrared rays and anions, preventing noise, blocking electromagnetic and harmful waves, promoting blood circulation and metabolism and stabilizing mental and physical conditions.

Description

technical field [0001] The present invention relates to a method of preparing a functional charcoal board by pasting printed tissue paper or chemical fiber non-woven fabric on one side of the charcoal board, which retains the characteristics of charcoal to provide aesthetic effects without losing the function of charcoal . Background technique [0002] Generally speaking, charcoal has the characteristics of humidification, ventilation, adsorption, heat storage, and can purify the air by absorbing unpleasant odors and toxic gases, emitting far infrared rays and anions, preventing noise and shielding electromagnetic waves and harmful waves. Also, it is used as a material that promotes blood circulation and metabolism and stabilizes mental and physical conditions. So, lately, a lot of homes are using charcoal, and putting some charcoal briquettes in a container, near computers and TVs or in closets and in the corners of living rooms, they don't look pleasing to the eye. The m...
