  • Patent number: 8748557
    Abstract: The present invention relates to an extreme low formaldehyde emission UF resin with a novel structure, and a process for its preparation. This UF resin is produced from formaldehyde, urea, a long chain multi-aldehyde prepolymer, and some modifiers. Its process follows three steps: weak caustic, weak acid and weak caustic. By using this prepolymer, the modified UF resin has stable alkyl ether structure, and the residual aldehyde groups on the UF polymer chain could accelerate cross-linking instead of dissociative formaldehyde. The UF resin made from this invention has extreme low dissociative formaldehyde and simple technology. The boards produced from this resin have good physical performance and water resistance. Moreover, the formaldehyde emission of the boards is extreme low, achieving Japan F???? grade, the average emission value ?0.3 mg/L.

  • Patent number: 6034201
    Abstract: A method of forming a urea formaldehyde resin includes the step of heating solid paraformaldehyde to a temperature of 60 to 120.degree. C. Urea is added to the heated paraformaldehyde to form a urea mixture, which is dry mixed and heated until a temperature of 80 to 110.degree. C. has been reached. After this, a methanolic quanine base is added to the urea mixture to form a quanine-urea-formaldehyde mixture, which is heated until the quanine-urea-formaldehyde mixture is liquefied and cooled to 65.degree. C. Then, the quanine-urea-formaldehyde mixture is heated until it boils, at which point it is condensed for a period of 30 to 100 minutes. After this, additional urea is added to the liquified urea mixture to form a urea enriched mixture. The urea enriched mixture is condensed for 90 to 180 minutes. After condensation, the urea enriched mixture is buffered with lactic acid to form a buffered mixture. This buffered mixture is cooled.
