Description

一种改性三聚氰胺硬质发泡材料及其制备方法
技术领域
本发明属于高分子材料技术领域，尤其涉及一种改性三聚氰胺硬质发泡材料及其制备方法。
背景技术
三聚氰胺硬质发泡材料是近年来发展起来的外墙外保温领域的一种新型材料，与聚氨酯、聚苯乙烯、酚醛树脂等其它硬质保温材料相比，在不添加其它阻燃剂的情况下即能达到阻燃效果，具有导热系数低、质轻、低烟、环保等特性；但三聚氰胺树脂合成及发泡过程中各种组分、参数控制要求比较严格，组分复杂、条件多变造成产品品质稳定性不是很好，而三聚氰胺所固有的三嗪环结构使得发泡材料易脆、掉粉率高、与基体粘结强度不够，同时也不能满足对使用强度要求较高的场所。
发明内容
本发明的目的是提供一种改性三聚氰胺硬质发泡材料及其制备方法，制备得到的三聚氰胺硬质发泡材料具有掉粉率低、闭孔率高、高强度、韧性好、后加工处理与基体粘结强度大的特点。
为达到上述目的，本发明采用的技术方案是：
一种改性三聚氰胺硬质发泡材料，由以下重量份数的原料组成:三聚氰胺30～60份，多聚甲醛15～40份，水10～35份，异丁醇5～20份，苯并噁嗪3～10份，聚乙烯醇缩丁醛5～15份。
一种改性三聚氰胺硬质发泡材料的制备方法，包括以下步骤：
(1)依次向反应釜中加入水、多聚甲醛、三聚氰胺，升温至85℃～90℃，反应0.5～1.0h，生成多羟基化三聚氰胺；
(2)将苯并噁嗪、聚乙烯醇缩丁醛在异丁醇中溶解后加入到步骤(1)所述的反应釜中，降温至70℃～80℃，反应1.0～2.0h生成预聚体树脂溶液；
(3)将预聚体树脂溶液与固化剂、发泡剂、乳化剂、调节剂等混合均匀后进行微波发泡，熟化后得到改性三聚氰胺硬质发泡材料。
进一步的，所述步骤(1)中的pH值为8.0～9.0，pH调节剂为三乙醇胺。
进一步的，所述步骤(2)中的pH值为6.5～7.5，pH调节剂为1%的盐酸溶液。
进一步的，所述步骤(3)中固化剂为甲酸、乙酸、乙二酸、氨基磺酸、羟基乙酸、乙二胺四乙酸中的至少一种；发泡剂为正戊烷、异己烷、二氯甲烷、三氯三氟甲烷、三氯三氟乙烷中的至少一种；乳化剂为十二烷基苯磺酸钠、十二烷基硫酸钠、脂肪醇聚氧乙烯醚硫酸钠中的至少一种；调节剂为四氟乙基四氟丙基醚、四氟乙基甲基醚、七氟异丙甲醚中的至少一种。
进一步的，所述步骤(3)中固化剂、发泡剂、乳化剂、调节剂的加入量均为预聚体树脂溶液质量的2～15%。
进一步的，所述固化剂的加入量为预聚体树脂溶液的4～10%；所述发泡剂的加入量为预聚体树脂溶液的3～12%；所述乳化剂的加入量为预聚体树脂溶液的5～8%；所述调节剂的加入量为预聚体树脂溶液的2～7%。
进一步的，所述步骤（3）中微波发泡功率为1500～2500W，发泡时间为3～5min；熟化温度为50～90℃，熟化时间为8～24h。
本发明具有的优点是：
1.本发明在改性过程中引入苯并噁嗪，使其先进行开环反应，后参与三维网状缩合反应，苯并噁嗪的氮氧六元噁嗪环结构使得三聚氰胺硬质发泡材料的强度进一步的提高；
2.本发明在改性过程中加入聚乙烯醇缩丁醛，聚乙烯醇缩丁醛优良的柔韧性及较好的粘结强度使得三聚氰胺硬质发泡材料韧性好、与基体粘结强度大，同时能够抑制掉粉现象；
3.本发明使用异丁醇预先溶解苯并噁嗪及聚乙烯醇缩丁醛，避免了苯并噁嗪与聚乙烯醇缩丁醛在水性环境中溶解度低的问题，同时异丁醇的沸点为107℃，与水较为接近，而又高于发泡剂的沸点，不会打破发泡过程各发泡助剂之间的平衡关系；
4.本发明在三维网状缩合反应阶段，温度降低，有利于控制反应速率，使得聚合物分子量分布均匀，降低树脂交联固化速度快进而凝结的风险；
5.本发明在发泡过程中引入氟醚类调节剂，能有效调节发泡材料的孔洞，使得闭孔率提高，材料质感强，吸水率低。
