METHOD OF PREPARING FIRE-RETARDANT WOOD

摘要

PURPOSE: A method for manufacturing impregnated flame resistance wood is provided to manufacture wood according to a flame resistance property stand by maintaining a temperature and humidity control function. CONSTITUTION: A dried wood is transferred to a vacuum chamber(S1). The vacuum chamber is maintained in a vacuum state by reducing the pressure of the vacuum chamber. Wood impregnation resin is injected into the vacuum chamber(S2). The wood impregnation resin is impregnated in wood by compressing the vacuum chamber(S3). The wood impregnation resin includes water, a water-soluble frame resistance material, and water-soluble ethylene glycol. The impregnated wood is dried(S4).
