Abstract

An environmentally friendly, bio-based binder system that is useful for the formation of fiberglass insulation, the system includes: A) an aqueous curable binder composition, which includes a carbohydrate and a crosslinking agent; and B) a dedust composition, which includes a blown, stripped plant-based oil and optionally at least one emulsifying agent. The bio-based binder system is typically heated to form a cured binder system.

Claims (24)

1. A bio-based binder system useful for the formation of rotary fiber insulation (for example fiberglass insulation), the system comprising:

A) an aqueous curable binder composition comprising:

(i) at least one carbohydrate;

(ii) at least one crosslinking agent; and

B) a dedust composition comprising:

(i) a blown, stripped plant-based oil having a viscosity of at least 200 cSt at 40° C., a flash point of at least 293° C., and having an acid value less than 5.0 mg KOH/gram,

wherein dedust composition B) comprises an oil-in-water emulsion, wherein a first emulsifier component is mixed into the blown, stripped plant-based oil of (i) and a second emulsifying component comprising carboxymethyl cellulose is mixed into an aqueous solution before the oil-in-water emulsion is formed by mixing the aqueous solution containing the second emulsifying component and the blown, stripped plant-based oil containing the first emulsifier component, and the first emulsifier component is selected from the group consisting of an alkoxylated fatty acid, a primary amine-based emulsifier, a secondary amine-based emulsifier, a tertiary amine-based emulsifier, and mixtures thereof; and

wherein the bio-based binder system comprises 10 part per million sulfur or less based on the weight of components A) and B), excluding water.

2. The bio-based binder system of claim 1 , wherein the emulsifier component comprises an alkoxylated fatty acid.

3. The binder system of claim 1 , wherein the dedust composition has less than 100 part per million sulfur, based on the weight of component B), excluding water.

4. The binder system of claim 3 , wherein the dedust composition has less than 40 part per million sulfur, based on the weight of component B), excluding water.

5. The binder system of claim 4 , wherein dedust composition has less than 20 part per million sulfur, based on the weight of component B), excluding water.

6. The binder composition of claim 5 , wherein the dedust composition has less than 10 part per million sulfur, based on the weight of component B)).

7. The bio-based binder system of claim 1 , wherein the first emulsifier component comprises a primary amine-based emulsifier.

8. The binder composition of claim 1 , wherein the first emulsifying component comprises a secondary amine-based emulsifier.

9. The binder system of claim 1 , wherein the binder system comprises 5 part per million sulfur or less based on the weight of components A) and B), excluding water.

10. The curable binder system of claim 1 , wherein the blown, stripped plant-based oil has a viscosity of at least 250 cSt at 40° C.

11. The binder system of claim 1 , wherein the blown, stripped plant-based oil has an acid value less than 4.0 mg KOH/gram.

12. The binder system of claim 1 , wherein the blown, stripped plant-based oil comprises a blown, stripped, bodied plant-based oil.

13. The binder system of claim 1 , wherein the blown, stripped plant-based oil is made from a blend of corn stillage oil and soybean oil in a weight ratio of corn stillage oil to soybean oil of from 5:95 to 95:5.

14. The binder composition of claim 1 , wherein the first emulsifying component comprises a tertiary amine-based emulsifier.

15. The binder system of claim 1 , wherein the blown, stripped plant-based oil has an hydroxyl number from about 1 mg KOH/gram to about 50 mg KOH/gram.

16. The binder system of claim 1 , wherein the blown, stripped plant-based oil has less than 50 ppm sulfur.

17. The binder system of claim 1 , wherein the weight ratio of binder composition A) to dedust composition B) is from about 100:1 to 100:34.
