View Patent ↗Dedusting agents for fiberglass products and methods for making and using the same are provided. The composition can include a binder and a dedusting agent. The dedusting agent can include an emulsion comprising one or more pitches, one or more fatty acids, one or more rosins, or any combination thereof.
1. A composition, comprising:
a binder; and
a dedusting agent comprising an emulsion comprising water, a pitch, a distilled tall oil, and a base compound, wherein the emulsion has a concentration of water ranging from about 30 wt % to about 75 wt %, a concentration of pitch ranging from about 20 wt % to about 50 wt %, and a concentration of distilled tall oil ranging from about 5 wt % to about 20 wt %, based on the combined weight of the water, pitch, and distilled tall oil.
2. The composition of claim 1 , wherein the binder comprises an aldehyde containing polymer, a mixture of Maillard reactants, a copolymer of one or more vinyl aromatic derived units and at least one of maleic anhydride and maleic acid, or any combination thereof.
3. The composition of claim 2 , wherein the mixture of Maillard reactants comprises at least one polycarboxylic acid, at least one of ammonia and an amine, and at least one carbohydrate source.
4. The composition of claim 1 , wherein the binder comprises an aldehyde containing polymer, and wherein the aldehyde containing polymer comprises a urea-formaldehyde polymer, a phenol-formaldehyde polymer, a melamine-formaldehyde polymer, or any combination thereof.
5. The composition of claim 1 , wherein the binder is combined with an extender to form a premix, and wherein the premix is combined with the dedusting agent.
6. The composition of claim 1 , wherein the pitch comprises a tall oil pitch.
7. A composition, comprising:
a binder; and
a dedusting agent comprising an emulsion comprising water, a pitch, a distilled tall oil, and a base compound, wherein the emulsion has a concentration of water ranging from about 30 wt % to about 75 wt %, a concentration of pitch ranging from about 20 wt % to about 50 wt %, a concentration of distilled tall oil ranging from about 5 wt % to about 20 wt %, and a concentration of base compound ranging from about 0.1 wt % to about 5 wt %, based on the combined weight of the water, pitch, distilled tall oil, and base compound.
8. The composition of claim 1 , wherein a source for at least a portion of the pitch comprises crude tall oil.
9. The composition of claim 7 , wherein a source for at least a portion of the pitch is derived from crude tall oil.
10. The composition of claim 1 , wherein the dedusting agent further comprises one or more oils.
11. The composition of claim 10 , wherein the one or more oils is present in an amount ranging from about 1 wt % to about 50 wt %, based on the combined weight of the one or more oils and the emulsion.
12. The composition of claim 1 , wherein the dedusting agent is present in an amount ranging from about 0.1 wt % to about 20 wt %, based on the combined weight of the binder and the dedusting agent.
13. The composition of claim 1 , wherein the dedusting agent further comprises one or more film forming polymers.
14. A fiberglass product, comprising:
a plurality of fibers; and
a composition comprising:
a binder; and
a dedusting agent comprising an emulsion comprising water, a pitch, a distilled tall oil, and a base compound, wherein the emulsion has a concentration of water ranging from about 30 wt % to about 75 wt %, a concentration of pitch ranging from about 20 wt % to about 50 wt %, and a concentration of distilled tall oil ranging from about 5 wt % to about 20 wt %, based on the combined weight of the water, pitch, and distilled tall oil, wherein the composition is at least partially cured.
15. The fiberglass product of claim 14 , wherein at least a portion of the pitch is derived from crude oil.
16. The fiberglass product of claim 14 , wherein the dedusting agent further comprises one or more mineral oils, one or more film forming polymers, or any combination thereof.
17. A process for preparing a fiberglass product, comprising:
contacting a plurality of fibers with a composition, the composition comprising:
binder; and
a dedusting agent comprising an emulsion comprising water, a pitch, a distilled tall oil, and a base compound, wherein the emulsion has a concentration of water ranging from about 30 wt % to about 75 wt %, a concentration of pitch ranging from about 20 wt % to about 50 wt %, and a concentration of distilled tall oil ranging from about 5 wt % to about 20 wt %, based on the combined weight of the water, pitch, and distilled tall oil;
collecting the contacted fibers to form a non-woven mat; and
heating the non-woven mat to at least partially cure the composition.
18. The process of claim 17 , wherein at least a portion of the are pitch is derived from crude oil.
19. The process of claim 17 , wherein the dedusting agent further comprises one or more mineral oils, one or more film forming polymers, or any combination thereof.
20. The composition of claim 1 , wherein the composition dries to a film such that a tack tester located on a surface of the film falls over in less than about 120 seconds when a 300 gram weight is removed after being placed for 5 seconds on a base of the tack tester, according to ASTM 1640-03.
21. The composition of claim 1 , wherein the composition dries to a film that is tack free, according to ASTM 1640-03.
22. The composition of claim 1 , wherein the dedusting agent has a solids concentration of from about 20 wt % to about 50 wt %, based on the weight of the dedusting agent.
23. The composition of claim 22 , wherein the solids in the dedusting agent have an average size of from about 0.1 μm to about 20 μm.
24. The composition of claim 22 , wherein the solids in the dedusting agent have an average size of less than 10 μm.
