Description

一种缓释型复合气相防锈纸的制备方法
技术领域
本发明涉及防锈纸技术领域，尤其涉及一种缓释型复合气相防锈纸的制备方法。
背景技术
气相防锈纸是含浸或者涂布不同组方的特殊物质-气相缓蚀剂（VCI），并经一系列后加工而成的特种防锈包装材料。气相防锈纸在常温下能挥发出特殊气体的包装材料，其挥发出来的气体能附着在金属表面形成保护膜，使金属表面钝化或使活性点失活，从而达到防锈效果。目前，气相防锈纸可以用于金属材料、零器件、电子元器件、军事装备、仪器等的包装，用途十分广泛。
CN104005304A将埃洛石纳米管-气相防锈剂复合物与聚合物乳液、改性淀粉等复配，并涂覆在纸张表面，经干燥、压光，得到具有缓释功能的气相防锈纸。该方法通过涂覆将气相防锈剂负载于纸张上，气相防锈剂与纸张结合不牢固，容易脱落，影响防锈功能。因此，需要作出改进。
发明内容
本发明目的就是为了弥补已有技术的缺陷，提供一种防锈效果持久、性能稳定的缓释型复合气相防锈纸的制备方法。
本发明是通过以下技术方案实现的：
一种缓释型复合气相防锈纸的制备方法，包括以下步骤：
（1）先将0.5-1重量份苯并三氮唑溶解于10-15重量份无水乙醇，然后加入5-10重量份纳米沸石粉搅拌混合均匀，之后放入真空箱中低压处理2-4h，将乙醇蒸干后研磨均匀，得到改性沸石粉；
（2）将0.5-1重量份壳聚糖加入80-100重量份醋酸溶液中充分溶解，然后加入5-10重量份步骤（1）得到的改性沸石粉搅拌均匀，经过喷雾干燥得到壳聚糖-改性沸石复合物；
（3）将4-8重量份步骤（2）得到的壳聚糖-改性沸石复合物、2-4重量份丙烯酰胺、0.3-0.5重量份聚山梨酯-80加入100-150重量份水中混合均匀并将pH调至7-8，然后加入0.05-0.1重量份引发剂，在氮气保护条件下于70-80℃搅拌反应2-4h，冷却后得到壳聚糖-改性沸石-聚丙烯酰胺复合溶胶；
（4）向纸浆中加入步骤（3）得到的壳聚糖-改性沸石-聚丙烯酰胺复合溶胶，抄造得到缓释型复合气相防锈纸，所述壳聚糖-改性沸石-聚丙烯酰胺复合溶胶的添加量为纸浆绝干浆质量的10-20%。
所述步骤（1）中低压处理条件为40-50kPa。
所述醋酸溶液的质量分数为1-1.5%。
所述步骤（2）中喷雾干燥条件为：进风温度100-105℃。
所述引发剂为过硫酸钾。
（1）本发明先通过负压浸渍法将防锈剂苯并三氮唑负载到纳米沸石粉上，然后喷雾干燥使壳聚糖包覆在纳米沸石粉表面，得到壳聚糖-改性沸石复合物，最后丙烯酰胺进行接枝共聚得到壳聚糖-改性沸石-聚丙烯酰胺复合溶胶，加入纸浆中抄造得到缓释型复合气相防锈纸，一方面通过多层包覆处理达到防锈剂缓释的目的，使防锈效果持久，另一方面防锈剂与纸张纤维的结合牢固，保证稳定的防锈性能。
（2）本发明在纸张的成型抄造加工过程加入防锈有效成分制备防锈纸，与涂覆法相比，既能减少涂层脱落带来的损失，又能减少工序，提高效率。
具体实施方式
一种缓释型复合气相防锈纸的制备方法，包括以下步骤：
（1）先将0.5kg苯并三氮唑溶解于10kg无水乙醇，然后加入5kg纳米沸石粉搅拌混合均匀，之后放入真空箱中低压处理2h，将乙醇蒸干后研磨均匀，得到改性沸石粉；
（2）将0.5kg壳聚糖加入80kg醋酸溶液中充分溶解，然后加入5kg步骤（1）得到的改性沸石粉搅拌均匀，经过喷雾干燥得到壳聚糖-改性沸石复合物；
（3）将4kg步骤（2）得到的壳聚糖-改性沸石复合物、2kg丙烯酰胺、0.3kg聚山梨酯-80加入100kg水中混合均匀并将pH调至7，然后加入0.05kg引发剂，在氮气保护条件下于70℃搅拌反应2h，冷却后得到壳聚糖-改性沸石-聚丙烯酰胺复合溶胶；
（4）向纸浆中加入步骤（3）得到的壳聚糖-改性沸石-聚丙烯酰胺复合溶胶，抄造得到缓释型复合气相防锈纸，所述壳聚糖-改性沸石-聚丙烯酰胺复合溶胶的添加量为纸浆绝干浆质量的10%。
所述步骤（1）中低压处理条件为40kPa。
所述醋酸溶液的质量分数为1%。
所述步骤（2）中喷雾干燥条件为：进风温度100℃。
所述引发剂为过硫酸钾。
