I claim: 1. a composition suitable for use in the manufacture of construction board comprising: an expanded mineral present at up to about 40% by weight; calcium sulfate present at up to about 60% by weight; and a synthetic binder, said synthetic binder being selected from the group consisting essentially of: (i) a vinyl acetate emulsion comprising a homogenous blend of suspended polyvinyl.
In order to produce a suspension having the desired particle size, the suspension is milled by various techniques such as, for example, conventional comminution and de-agglomeration, grinding in an air-jet mill or impact mill, a ball mill, dry milling, wet milling, colloidal mill, and dyano mill; and micronization and microfluidization.
In this example, first the dry ingredients were combined together and blended until a homogeneous mix was achieved, these dry ingredients being plaster grade expanded perlite with a loose density of 6 to 8 pounds per cubic foot, calcined gypsum stucco, starch, ball mill.
