COATED PRESSING SURFACES FOR ABRASION RESISTANT LAMINATE AND MAKING LAMINATES THEREFROM

摘要

A PRES PLATE FOR PRODUCING DECORATIVE LAMINATE FROM RSIN IMPREGNATED PAPER, WITH ALUMINA PARTICLES ON ITS PRESSING SURFACE, IS COATED WITH DIBORIDES SELECTED FROM THE GROUP CONSISTING OF HAFNIUM DIBORIDE, MOLYDBENUM DIBORIDE, TANTALUM DIBORIDE, TITANIUM DIBORIDE, TUNGSTEN DIBORIDE, VANADIUM DIBORIDE, OR ZIRCONIUM DIBORIDE OR MIXTURES THEREOF FOR MAKING THE PRESS PLATE RESISTANT IS TO SCRATCHING. THE PREFERRED DIBORIDES ARE TITANIUM AND ZIRCONIUM. THE MOST PREFERRED DIBORIDE IS TTTANIUM. THE COLOR, GLOSS AND SURFACE APPEARANCE OF LAMINATE PRESSED WITH A TITANIUM DOBORUDE COATED PRESS PLATE IS SUBSTANTIALLY THE SAME AS LAMINATE PRESSED WITH THE PRESS PLATE BEFORE COATING.
