摘要
以尿素、间苯二酚为改性剂，在碱性条件下制备中温固化酚醛树脂。利用Design-Expert软件建立数学模型，以胶合强度为响应值，优化酚醛树脂的原料配比。结果表明，中温固化酚醛树脂原料的最佳配比为：甲醛与苯酚摩尔比为2？32，氢氧化钠与苯酚摩尔比0？56，尿素加量为苯酚质量的20？03％，间苯二酚加量为苯酚质量的9？98％。在此条件下制备的酚醛树脂可以在105～115℃下固化。
Urea and resorcinol were used as modifiers to prepare mid-temperature curing phenol-formaldehyde resin （PF） in alkaline condition, and the response surface methodology was used to optimize the effects of raw materials ratio on bond-ing strength. The optimal raw materials ratio of PF were determined as follows：molar ratios of formaldehyde and alkali to phenol were 2？32 and 0？56, respectively;and the mass of urea and resorcinol to phenol were 20.03%and 9？98%, respec-tively. Under these raw materials ratio, the curing temperature of the PF was in the range of 105-115℃.
