摘要
采用正交实验研究了摩尔比(A)、木质素用量(B)、催化剂量(C)等3个因素对木质素改性酚醛树脂性能的影响,以木质素改性酚醛树脂为基体制备了模塑料并对其性能进行了测试。正交实验结果表明:木质素用量对聚速、游离酚、废水酚和苯酚反应率具有最主要影响,催化剂用量是黏度和软化点的最主要影响因素。在本研究范围内,制备模塑料用的木质素改性酚醛树脂的优选实验方案为:摩尔配比为0.84、木质素用量为10%、催化剂用量为0.9%,采用木质素改性酚醛树脂制备的模塑料具有更好的机械性能和耐热性能。
The effects of the molar ratio of the raw materials,quantity of lignin,amount of catalyst on the properties of the modified phenolic resin were studied by orthogonal test.The phenolic moulding compounds was prepared based on lignin modified phenolic resin and its properties were tested.The orthogonal results showed that the amount of lignin was the key influencing factor of the curing time,free phenol of resin and waste water,the response rate of phenol.While the quantity of catalyst was the key influencing factor of the viscosity and soften point.For this research,the optimum synthetic parameters of lignin modified phenolic resin suitable for composite were as follows:the molar ratio was 0.84,the amount of lignin was 10%,the quantity of catalyst was 0.9%.The moulding compounds based on lignin modified phenolic resin had better physical performance and thermotolerant performance.
