Description

一种添加改性填料的发泡材料
技术领域
本发明涉及一种发泡材料，特别是一种添加改性填料的发泡材料。
背景技术
以聚氯乙烯制备的发泡板材主要用于广告柜、浴室柜的制造，最早从欧洲引进设备和技术，引用的产品标准也是参考了欧洲的标准，板材的密度较大。近几年随着国产设备的发展尤其是助剂的发展，板材的密度有了大幅度降低，可达到0.4~0.45g/cm3之间，从而大大提高了板材的应用空间，且降低了使用成本，但是如何使板材密度进一步降低，且仍然能达到较好的使用性能，是轻质板材研究的一个瓶颈。阻燃发泡材料因其具有质轻、阻燃等性能，被广泛用于各种需要防火的场合。但现有阻燃发泡材料，其阻燃性能仍不是太理想，无法满足某些防火要求较高的场合，在使用上还是受到一些局限。
发明内容
本发明的目的是提供一种添加改性填料的发泡材料，具有阻燃性优异、质轻、回弹性好、隔音、保温等优点。。
为了实现本发明的目的，本发明通过以下方案实施：
一种添加改性填料的发泡材料，由下列重量份的原料制成：线性低密度聚乙烯80-90、SG-5聚氯乙烯12-16、碳酸钙粉20-24、硬脂酸2-3、氧化锌2-3、偶氮二甲酰胺4-5、氯化石蜡5-7、聚对苯二甲酸二乙酯3-5、二氧化钛粉4-6、亚磷酸三苯酯2-3、改性填料6-8；
所述改性填料通过以下方法制备：称取下列重量份的原料：凹凸棒土90-100、硅藻土20-24、秸秆灰烬50-55、十二烷基苯磺酸钠2-3、碳酸氢铵2-3、云母3-4、2-氨基-2-甲基-1-丙醇3-4、阳起石5-6、硫酸镁2-3、纳米二氧化硅1-2、环氧大豆油2-3、偏硅酸钠2-3、亚硒酸钠4-5；制备方法是将凹凸棒土、硅藻土、云母、阳起石放入煅烧炉中，在530-570℃下煅烧4-5小时，取出，与秸秆灰烬、碳酸氢铵混合，研磨至得到300-400目粉末，然后，再加入纳米二氧化硅、偏硅酸钠、2-氨基-2-甲基-1-丙醇、环氧大豆油混合，继续研磨30-45分钟，至充分分散，再加入其它剩余成分，继续研磨30-45分钟后，在1500-1800转/分下搅拌15-30分钟，即得改性填料。
本发明所述添加改性填料的发泡材料，由以下具体步骤制备而成：
（1）将除改性填料、偶氮二甲酰胺之外的其它各物料混合，升温至100-120℃，混炼8-12分钟；
（2）将混炼好的物料加入改性填料、偶氮二甲酰胺在90-100℃进行二次混炼6-10分钟；
（3）将二次混炼好的物料开片、出片，送入成型设备中进行预成型，成型压力为4-6MPa，15-20秒后取出；
（4）将片料加到预热的模具中，于平板硫化机上140-160℃温度下加压至6-7MPa，保压6-12min，去压发泡，冷却至常温即得。
本发明添加改性填料具有十分优异的阻燃效果，还赋予本发明泡沫材料优良的力学性能回弹性好，且具有较强的隔音性能，并同时保持了聚氯乙烯发泡材料的保温、质轻、吸水率低等优点，操作简单易得，成本低。
