Abstract: PURPOSE: A hull board emitting far-infrared ray and a producing method thereof are provided to use resource effectively for producing a value added product and to be used in a house for enhancing health of people. CONSTITUTION: A hull board of intermediate density is produced by using MDI(Diphenylmethane Diisocyanate) resin at a temperature of 171°C, amount of resin of 12%, and pressurizing time of 7 minutes or by using urea resin or tannin resin at a temperature of 171°C, amount of resin of 18%, and pressurizing time of 5 minutes. Also, a hull-wood mixed board is produced by mixing the hull and the wood in the ratio of 25: 75 while crushing the hull for 1 minute at a crushing pressure of 25kgf/cm¬2. Therefore, the emitting rate of far-infrared ray is 89.5-96.1% at the wavelength of 6-18 micrometers.

Abstract: PURPOSE: Provided is a method for producing an adhesive formed by combining a blood plasma of slaughtered livestock and phenol synthetic resin for production of ligneous materials. CONSTITUTION: The method comprises the steps of: (i) precipitating a centrifuged supernatant of blood of slaughtered livestock with TCA(trichloroacetic acid, final concentration 2%) or HCl(final concentration 0.6 N), (ii) combining the precipitated blood plasma with high-alkaline phenol formaldehyde(PF) resin(for example, PF 15-20% NVC 100 g, TCA/HCl precipitated plasma BNVC 15-20 g), and replacing 60% or more of phenol resin with the precipitated plasma to form an inexpensive and eco-friendly PF-plasma combined resin for production of ligneous material.
