Abstract
Binder compositions for fiberglass are disclosed, comprising a polycarboxylic acid such as polyacrylic acid and a crosslinking agent. The crosslinking agent comprises a polyhydroxy component formed from a reaction of an epoxidized plant oil with an amine and optionally with a phenolic compound. The molar ratio of the amine to the epoxidized plant oil at the beginning of said reaction may be greater than 1:1. Methods of making the binders and fiber-containing composites made with said binders are also described.

A binder composition for fiberglass, comprising a polycarboxylic acid and a crosslinking agent, wherein the crosslinking agent comprises a polyhydroxy component derived from epoxidized plant oil, the polyhydroxy component formed from a reaction of an epoxidized plant oil with an amine and optionally with a phenolic compound.
A binder composition for fiberglass, comprising a formaldehyde-based binder and a crosslinking agent, wherein the crosslinking agent comprises a polyhydroxy component derived from epoxidized plant oil, wherein the polyhydroxy component is formed from a reaction of an epoxidized plant oil with an amine and optionally with a phenolic compound.
A binder composition for fiberglass, comprising a formaldehyde-free binder and a crosslinking agent, wherein the crosslinking agent comprises a polyhydroxy component derived from epoxidized plant oil, wherein the polyhydroxy component is formed from a reaction of an epoxidized plant oil with an amine and optionally with a phenolic compound
A method of forming a binder composition for fiberglass, comprising:
- reacting an epoxidized plant oil with an amine optionally in the presence of a catalyst to form a polyhydroxy crosslinking agent, wherein the molar ratio of the amine to the epoxidized plant oil at the beginning of said reacting step is greater than 0.5:1;
- and
- mixing said polyhydroxy crosslinking agent with a polycarboxylic acid to form the binder composition.
A cured binder composition for fiberglass, comprising:
- (i) a crosslinked polycarboxylic acid, and (ii) a dedusting agent, wherein the dedusting agent comprises a polyhydroxy component formed from a reaction of an epoxidized plant oil with an amine, wherein the molar ratio of the amine to the epoxidized plant oil at the beginning of said reaction is greater than 0.5:1.
A fiber-containing composite, comprising:
- (a) woven or non-woven fibers;
- and
- (b) a cured binder that holds the fibers together, wherein the binder comprises a polycarboxylic acid crosslinked by a crosslinking agent, wherein the crosslinking agent comprises a polyhydroxy component formed from a reaction of an epoxidized plant oil with an amine, wherein the molar ratio of the amine to the epoxidized plant oil at the beginning of said reaction is greater than 0.5:1.
