METHOD FOR ENHANCING SURFACE FRICTIONAL FORCE OF TILE AND SURFACE FRICTIONAL FORCE ENHANCER COMPOSITION

摘要

PURPOSE: To obtain a surface frictional force enhancer compsn. capable of preventing slippage on a tile and to provide a method for enhancing the surface frictional force of the tile by forming micropores of certain size in the surface of the tile to suppress the formation of a water film on the surface of the tile. ;CONSTITUTION: This surface frictional force enhancer compsn. comprises 2-10 pts.wt. hydrofluoric acid or 3-15 pts.wt. ammonium fluoride, 1-20 pts.wt. etching relaxant and 1-20 pts.wt. dispersant. The surface of a tile is coated with a mixture of 2-40 parts of the compsn. and 60-98 pats water, allowed to stand at ordinary temp. for 3-10 min and washed with water. Micropores of about 10-900 μm size are uniformly formed in the surface of the tile, the lubricating action of a water film is inhibited and slippage is effectively prevented.;COPYRIGHT: (C)1994,JPO
