Zusammenfassung:	DESCRIBED IN THE PRESENT INVENTION IS A PROCESS FOR THE PREPARATION OF AN ADHESIVE FOR A LIGNOCELLULOSE PRESSED BOARD, WHICH COMPRISES INJECTING A FIRST STREAM FORMED OF (A) AN ORGANIC ISOCYANATE COMPOUND AND A SECOND STREAM FORMED OF (B) A REACTIVE EMULSIFIER AND (C) AN EMULSIFYING MEDIUM AND OPTIONALLY A MOLD RELEASE AGENT INTO A MIXING CHAMBER UNDER A HIGH PRESSURE OF 40 TO 300 KG/CM2 AND THEN MIXING THEM. ACCORDING TO THIS INVENTION, A PREPARATION PROCESS OF AN ADHESIVE OPTIMUM FOR THE CONTINUOUS PROCESS SUITED FOR THE INDUSTRIAL PRODUCTION IS PROVIDED. OWING TO GOOD RELEASABILITY OF THE INVENTION ADHESIVE AT THE TIME OF HOT PRESSING, THIS ADHESIVE IS SUITED FOR THE INDUSTRIAL PRODUCTION OF A HIGH-QUALITY AND INEXPENSIVE LIGNOCELLULOSE PRESSED BOARD WITH GOOD PRODUCTIVITY.(FIG. 1)
