NOVEL HYBRID BINDER WITH NATURAL COMPOUNDS FOR LOW EMISSION PRODUCTS |
摘要 |
Resin compositions (A) and (B) are described: wherein resin composition (A) comprises a naturally occurring component or derivative thereof comprising protein, an aromatic hydroxyl compound-aldehyde resin and an amino resin, wherein the naturally occurring component or derivative thereof is chemically bound to the aromatic hydroxyl compound-aldehyde resin to form an ncPF resin and the naturally occurring component or derivative thereof is optionally chemically bound to the amino resin; wherein resin composition (B) comprises a condensation product of a naturally occurring component or derivative thereof, an aromatic hydroxyl compound-aldehyde resin and at least 20 wt% of urea based on the total mass of the resin composition, wherein at least 50wt% of the naturally occurring component or derivative thereof is chemically bound directly or indirectly to the aromatic hydroxyl compound-aldehyde resin (ncPF), and wherein the naturally occurring component or derivative thereof comprises protein. The resin compositions can be used as a binder for lignocellulosic or cellulosic materials which have an excellent combination of low formaldehyde emissions and high strength. Also described are low formaldehyde emissions wood products comprising unique binder combinations. |
