Abstract
Dedust compositions suitable for use as dedust oil for mineral wool applications comprise a) from 95 percent by weight to 99.99 percent by weight of a triacyl glyceride sourced from a plant or animal oil, the triacyl glyceride having an IV of from 45 to 70, a viscosity at 30 C of from 30 mPa·s to 80 mPa·s, and a Solid Fat Content of 15% w/w or less at 10 C; and b) from 100 ppm to 2,500 ppm of an antioxidant. The dedust composition exhibits a flash point of at least 280 C. In aspects, the dedust composition is liquid at 23 C. In aspects, the triacyl glyceride is palm super olein.
Claims19
A method of making a bonded mineral fiber-containing product comprising
- mixing a dedust composition exhibiting a flash point of at least 280° C. with a binder composition to form a binder/dedust mixture, wherein the dedust composition comprises:
- a) from 95 percent by weight to 99.99 percent by weight of a triacyl glyceride sourced from a plant or animal oil, the triacyl glyceride having an IV of from 45 to 70, the triacyl glyceride has an Oxidation Induction Time (OIT) of at least 22 minutes at 130 C, a viscosity at 30° C. of from 30 mPas to 80 mPas, and a Solid Fat Content of 15% w/w or less at 10° C., wherein the triacyl glyceride has not been chemically reacted to form a modified chemical compound per se;
- and
- b) from 100 ppm to 2,500 ppm of an antioxidant;
- applying the binder/dedust mixture to mineral fibers;
- collecting and compressing the mineral fibers in the shape of the desired product;
- and
- curing the binder, thereby forming the bonded mineral fiber-containing product.
