Abstract
A method for dedusting a fibrous insulation product using an epoxidized vegetable oil, such as epoxidized soybean oil, having a iodine value less than 10 cg I2 per gram and an oxidation exotherm by pressure differential scanning calorimeter of less than 500 joules/gram at an oven temperature of 130° C. and an oxygen inlet pressure of 500 PSIG. The fibrous insulation product typically is made with a binder composition that is applied to mineral fibers in addition to the epoxidized vegetable oil prior to the binder composition being cured.
Claims42
A method for making a fibrous insulation product, the method comprising:
- forming a plurality of randomly oriented mineral fibers;
- applying a binder composition to the mineral fibers to form a fibrous insulation blanket;
- applying a dedust composition comprising epoxidized soybean oil to the mineral fibers or the fibrous insulation blanket;
- and
- heating the fibrous insulation blanket to form the fibrous insulation product, wherein the epoxidized soybean oil has (i) a viscosity of from 120 to 250 cSt at 40° C., (ii) an AV of less than 1 mg KOH/g, (iii) a Cleveland Open Cup Flash point of at least 280° C., (iv) an iodine value of less than 10 cg I2 per gram, (v) an oxirane content of at least 4.5 wt %, and (vi) an oxidation exotherm by pressure differential scanning calorimeter of less than 500 joules/gram at an oven temperature of 130° C. and an oxygen inlet pressure of 500 PSIG.
