摘　　要：以酚醛树脂和脲醛树脂为主要原料制备了可降解的插花泥，考察了影响其吸水性和保水性的一些因素。最佳的制备条件为：100份酚醛树脂，30份脲醛树脂，6份表面活性剂，10份发泡剂，20份固化剂；对甲苯磺酸-磷酸为固化剂，戊烷为发泡剂，发泡温度为50～55％；在优化条件下制得的花泥其吸水率可达38．4倍，5d后的保水率仍为80．2％。Using phenol formaldehyde resin and urea-formaldehyde resin as raw materials, pentane as foaming agent, paratoluene sulfonic acid and phosphaoril acid as curing agent, the multiplex degradable flower mud was prepared at a foaming temperature of 50-55℃. Some factors influencing water absorption rate and retention rate were investigated.The optimal recipe was as follows：surfactant 6g,foaming agent 10g, curing agent 20g were employed in the mixture of 100 g phenol formaldehyde resin and 30g urea-formaldehyde resin.Under the optimum conditions,the water absorption rate of flower mud is up to 38.4 times and the retention rate is still 80.2% after 5d.
