Abstract:
A method of preparing a synthetic solid surface material having a simulated burled wood effect in a pattern therethrough comprising the steps of:a. preparing a matrix of isophthalic polyester alumina trihydrate (ATH, iron oxide pigments and pearlescent mica pigments; b. mixing said matrix completely in a vessel; c. catalyzing said material with methyl ethyl ketone peroxide (MEKP) in said vessel; d. placing said vessel containing the catalyzed matrix into a vacuum for removing any tapped air in said matrix; e. removing said catalyzed matrix from said vacuum; f. preparing a burling effect material which comprises polyester resin, ATH, iron oxide pigments, and pearlescent mica pigments wherein said iron oxide and pearlescent pigments are chosen to simulate the color of the grain of a wood to be simulated and are a darker color than said mat and said burling effect material has a specific gravity slightly less than the composition of said matrix; g. catalyzing said burling material with methyl ethyl ketone peroxide (MEKP); h. preparing a mixture of the catalyzed burling effect material and said catalyzed matrix by said catalyzed burling effect material into said catalyzed matrix until a desired contrast occurs between said catalyzed matrix and said catalyzed burling effect material; i. pouring said mixture into a mold; j. curing said mixture into a hardened slab which comprises a top surface and a bottom surface wherein said bottom surface is in contact with said mold; and k. removing said slab from said mold.
