Abstract
The present invention provides a binder composition comprising a low molecular weight polycarboxylic acid, such as maleic anhydride, and a low molecular weight poly alcohol, such as polyvinyl alcohol, that exhibits improved cure performance with reduced emissions without sacrificing the performance of the final product or complication the manufacturing process. The binder composition may also incorporate a cure catalyst or accelerant such as sodium hypophosphite.
Claims13
A binder composition comprising:
- a low molecular weight polyalcohol, the polyalcohol comprising an oligomer or polymer of one or more alcohols and having a number average molecular weight of at least 200;
- a low molecular weight polycarboxylic acid;
- and
- water.
A method of manufacturing a bound fiber batt comprising the steps of:
- providing a fiber batt comprising a collection of fibers;
- applying an aqueous binder premix solution to the batt to form a coated batt;
- and
- curing the coated batt under conditions sufficient to bind adjacent fibers with a thermoset resin to form the bound fiber batt;
- wherein the aqueous binder premix solution comprises a low molecular weight poly alcohol and a low molecular weight polycarboxylic acid.
