IMPROVED AMINO RESIN PERFORMANCE WITH SULFONATED LIGNIN
20230132358 · 2023-04-27 · ·

A resin system and methods of making resin system wherein lignosulfonate is added to urea-formaldehyde and melamine-urea-formaldehyde adhesives. Lignosulfonate is added to the resins which improves the performance characteristics of the adhesive while reducing environmental impact by consuming byproducts from other industrial processes. The resin system includes a urea-formaldehyde (UF) resin or melamine-urea-formaldehyde (MUF), prepared in at least two stages wherein the UF resin or MUF resin has a molar ratio (MR) of total moles formaldehyde to total moles urea plus, if present, the one or more melamine compounds of from about 0.25:1 to about 2.50:1, and wherein one or more lignosulfonate compounds are included in an amount of from about 0.1-30 wt. %, based on a total weight of the resin system, and wherein the resin system has a buffer capacity of 2-400 mL of 0.1 N HCl by the ATV Method for a period of time of at least about 20 days at 25° C.

HIGH ACID ACRYLIC STYRENE ACRYLIC AND ACRYLIC EMULSION COPOLYMER MODIFIED UREA FORMALDEHYDE BINDERS FOR MINERAL FIBERS
20230174771 · 2023-06-08 ·

The present invention provides modified urea formaldehyde (UF) resin binder compositions and mineral fiber mats having an emulsion polymer modifier comprising, in copolymerized form, from 5 to 25 wt. % of co polymerized carboxylic acid functional monomers. The emulsion polymers have a measured glass transition temperature (DSC) ranging from −40° C. to 70° C. and a large average particle size. Further, the emulsion polymers comprise less than 30% of the copolymerized acid in neutralized form and do not excessively thicken aqueous compositions containing them. The modified UF resin binder compositions enable good dilution stability in use and high tensile strength in products containing them.
