    • Infinitely water soluble, storage stable, low molecular weight, amine-modified resins/binders (e.g., phenol-formaldehyde resole resins and binders made therefrom) are used, to produce low odor fiberglass products, such as fiberglass insulation for automobile headliners and room dividers. The cured, bonded fiberglass products have low TMA (trimethylamine) emission because the free formaldehyde in the resin has been scavenged with melamine, which resists thermal decomposition, and because the binder contains a relatively low urea content, which is a TMA contributor. The resole resin production process includes adding two different formaldehyde scavengers (e.g., melamine and urea) to produce a modified phenol-formaldehyde resole resin. This resole resin is produced into a binder by mixing with water, optionally in the presence of a latent acid catalyst (e.g., an ammonium salt of a strong acid). The binder can be applied to a fiberglass base material, dried, stored for an extended time period, and then cured and shaped into a final desired shape.
    • 使用无限水溶性,储存稳定的低分子量胺改性树脂/粘合剂(例如,苯酚甲醛甲阶酚醛树脂和由其制成的粘合剂),以生产低气味玻璃纤维产品,例如用于汽车头饰的玻璃纤维绝缘体和室内分隔器 。 固化的粘合玻璃纤维产品具有低TMA(三甲胺)排放,因为树脂中的游离甲醛已经被三聚氰胺清除,因此耐热分解,并且由于粘合剂含有较低的尿素含量,这是TMA贡献者。 甲阶酚醛树脂的制备方法包括加入两种不同的甲醛清除剂(例如三聚氰胺和尿素)以产生改性的酚醛树脂树脂。 任选地在潜酸催化剂(例如强酸的铵盐)的存在下,将该甲阶酚醛树脂与水混合制成粘合剂。 粘合剂可以应用于玻璃纤维基材,干燥,长时间储存​​,然后固化并成型为最终所需的形状。

    • The invention concerns a process for preparing aqueous aminoplastic resins which are suitable as binders for producing derived timber products. The process is characterized in that: a) 1 mole melamine; b) a concentrated aqueous solution of 0.5 to 5 moles urea and 3 to 6 moles formaldehyde per mole of urea, in which urea and formaldehyde can also be present in the form of their reaction products, c) 0.01 to 0.5 moles phenol or a phenol derivative which can be polycondensed, d) 0 to 9 moles formaldehyde, and e) 0 to 1 mole of a further compound which can be polycondensed are reacted with one another at 50 to 100 DEG C and a pH of 7.5 to 10.0 until the solution attains a viscosity of 10 to 1500 mPa.s, after which this solution is left to cool, and f) is mixed with 0.55 to 0.75 moles urea per mole of the total amount of urea used as components (b) and (f).
