摘要
介绍了以苯酚、尿素、三聚氰胺、甲醛、糠醇为原料,经一步缩聚反应、中和水洗、减压脱水等工序制备新型铸造用酚醛树脂粘结剂的生产技术,讨论了工艺参数及操作对产品质量的影响。
Using phenol, urea, melamine, formaldehyde and furfuryl alcohol as raw materials, a new type of phenolic resn adhesive for casting is prepared by condensation polymerization, meutralization and vacuum dehydration. The technological parameters and influencing factors on product qualiry are discussed.
