Description

一种闭孔剂的制备方法及所得产物
技术领域
本发明属于多孔材料领域，具体涉及一种制备泡沫树脂所用的闭孔剂。
背景技术
近几年市场出现的三聚氰胺海绵又称密胺海绵，是由碱性三聚氰胺甲醛树脂进过特殊工艺微波发泡制成的纳米级三维网状交联结构的软质热固性泡沫塑料。密胺海绵属于完全开孔型泡沫，其开孔率高达99.9％阻燃性能高，烟密度低，是较好的保温、隔热、隔音、轻质材料。在建筑装饰、交通车辆、水上船舶、航空航天、机电设备、工业吸音保温等领域中获得广泛使用(王东卫等，密胺泡沫的制备改性及性能研究，功能材料，2012年24期)。
密胺海绵在我国是一项新兴产业，其市场需求量巨大。根据海绵上开孔类型，分为闭孔(孔眼与孔眼之间互不相通)、开孔(孔眼与孔眼相互之间未被孔壁完全隔开，具有一定程度的连同性)和混合孔(兼有开孔和闭孔两种结构)三种。密胺海绵泡沫的开孔结构吸水率极高达到350％，吸水后的的泡沫重量增加，保温隔热隔音性能急剧下降，更容易在空洞中滋生细菌产生霉变，开孔结构空气产生对流导热保温性能有限在保温隔热方面应用受到限制。
当前市场上还没有专门针对密胺海绵的闭孔剂。
发明内容
针对本领域存在的不足之处，本发明的目的是提出一种闭孔剂的制备方法。
本发明的另一目的是提出所述制备方法制得的闭孔剂。
本发明的第三个目的是提出所述闭孔剂的应用
为实现本发明的上述目的的技术方案为：
一种闭孔剂的制备方法，包括步骤：
1)向甲苯-2,4-二异氰酸酯中加入苯酐，常温下搅拌反应；甲苯2,4二异氰酸酯和苯酐的体积质量比为100mL：4～8g；
2)向反应体系中加入聚乙二醇200，反应温度为65～75℃，聚乙二醇加入后保持温度65～75℃继续反应30～40分钟得到闭孔剂。
其中，所述甲苯二异氰酸酯为甲苯-2,4-二异氰酸酯和/或甲苯-2,6-二异氰酸酯。通常市购的甲苯二异氰酸酯为甲苯-2,4-二异氰酸酯和/和甲苯-2,6-二异氰酸酯的混合物。但是发明人在试验中发现，高含量的甲苯-2,6-二异氰酸酯加入后反应极剧烈，无法控制反应进程，用含有80％的甲苯-2,4-二异氰酸酯效果最好。
其中，所述步骤1)还加入增韧剂A-60(深圳金大全科技有限公司生产)，增韧剂和甲苯-2,4-二异氰酸酯的体积比为10～20：100。
其中，所述步骤2)中，聚乙二醇和甲苯-2,4-二异氰酸酯的体积比为40～60：100。
其中，所述步骤2)中，用滴加聚乙二醇的速度控制反应温度在68～72℃。
本发明所述的制备方法制备得到的闭孔剂。
所述闭孔剂在制备密胺泡沫中的应用。
应用所述闭孔剂制备密胺泡沫的方法，包括步骤：按照质量份，取可发型密胺树脂(市购可得)100份，加入闭孔剂30～40份，闭孔辅助剂4～6份，表面活性剂1～3份，固化剂2～3份，发泡剂1～2份，经高速搅拌均匀，置于模具中微波发泡。
其中，所述固化剂为草酸、甲酸、磷酸、对甲苯磺酸、三聚催化剂、氯化铵、硫酸镁中的一种或几种，所述表面活性剂为十二烷基磺酸钠、硅油、硬脂酸、氨基酸、聚三梨醇、脂肪酸甘油酯中的一种或几种，所述发泡剂为戊烷、丁烷、乙烷、庚烷，二氯乙烷、三氯氟甲烷、二氯二氟甲烷中的一种或几种。
优选地，所述闭孔辅助剂为乳化硅油、苯酐聚酯多元醇、异氰酸酯质量比1：1：0.3的混合物。
本发明的有益效果在于：
本发明针对现有密胺海绵泡沫开孔或部分开孔，导致材料脆性大的问题，提出新型的闭孔剂的制备方法。
制备闭孔剂时加入苯酐和助剂，用活性的聚氨酯解决密胺泡沫的开孔问题。制得的闭孔剂不仅能有效减少密胺海绵开孔率，而且提高了海绵的韧性，使产品品质提高、应用扩大。
